Fix write endianness/size problem for fast tracepoint enabled flag
I am sending this fix on behalf of Par Olsson, as a follow-up of this
one:
https://www.sourceware.org/ml/gdb-patches/2015-10/msg00196.html
This problem is exposed when enabling/disabling fast tracepoints on big
endian machines. The flag is defined as an int8_t, but is written from
gdbserver as an integer (usually 32 bits). When the agent code reads it
as an int8_t, it only considers the most significant byte, which is
always 0.
Also, we were writing 32 bits in an 8 bits field, so the write would
overflow, but since the following bytes are padding (the next field is
an uint64_t), it luckily didn't cause any issue on little endian
systems.
The fix was originally tested on ARM big endian systems, but I don't
have access to such a system. However, thanks to Marcin's PowerPC fast
tracepoint patches and gcc110 (big endian Power7) on the gcc compile
farm, I was able to reproduce the problem, test the fix and write a
test (the following patch).

Deliver signal in hardware single step
GDBserver doesn't deliver signal when stepping over a breakpoint even
hardware single step is used. When GDBserver started to step over
(thread creation) breakpoint for mutlit-threaded debugging in 2002 [1],
GDBserver behaves this way.
This behavior gets trouble on conditional breakpoints on branch to
self instruction like this,
0x00000000004005b6 <+29>: jmp 0x4005b6 <main+29>
and I set breakpoint
$(gdb) break branch-to-self.c:43 if counter > 3
and the variable counter will be set to 5 in SIGALRM signal handler.
Since GDBserver keeps stepping over breakpoint, the SIGALRM can never
be dequeued and delivered to the inferior, so the program can't stop.
The test can be found in gdb.base/branch-to-self.exp.
GDBserver didn't deliver signal when stepping over a breakpoint because
a tracepoint is collected twice if GDBserver does so in the following
scenario, which can be reproduced by gdb.trace/signal.exp.
- program stops at tracepoint, and tracepoint is collected,
- gdbserver starts a step-over,
- a signal arrives, step-over is canceled, and signal should be passed,
- gdbserver starts a new step-over again, pass the signal as well,
- program stops at the entry of signal handler, step-over finished,
- gdbserver proceeds,
- program returns from the signal handler, again to the tracepoint,
and thus is collected again.
The spurious collection isn't that harmful, IMO, so it should be OK
to let GDBserver deliver signal when stepping over a breakpoint.

Add target descriptions for AVX + MPX
The current MPX target descriptions assume that MPX is always combined
with AVX, however that's not correct. We can have machines with MPX
and without AVX; or machines with AVX and without MPX.
This patch adds new target descriptions for machines that support
both MPX and AVX, as duplicates of the existing MPX descriptions.
The following commit will remove AVX from the MPX-only descriptions.

Fix PR gdb/19250: ptrace prototype is not detected properly in C++ mode
The ptrace args/return types detection doesn't work properly in C++
mode, on non-GNU/Linux hosts. For example, on gcc70 (NetBSD 5.1),
where the prototype is:
int ptrace(int, __pid_t, void*, int);
configure misdetects it as:
$ grep PTRACE_TYPE config.h
#define PTRACE_TYPE_ARG1 int
#define PTRACE_TYPE_ARG3 int *
#define PTRACE_TYPE_ARG4 int
/* #undef PTRACE_TYPE_ARG5 */
#define PTRACE_TYPE_RET int
resulting in:
../../src/gdb/amd64bsd-nat.c: In function 'void amd64bsd_fetch_inferior_registers(target_ops*, regcache*, int)':
../../src/gdb/amd64bsd-nat.c:56: warning: dereferencing type-punned pointer will break strict-aliasing rules
../../src/gdb/amd64bsd-nat.c: In function 'void amd64bsd_store_inferior_registers(target_ops*, regcache*, int)':
../../src/gdb/amd64bsd-nat.c:104: warning: dereferencing type-punned pointer will break strict-aliasing rules
../../src/gdb/amd64bsd-nat.c:110: warning: dereferencing type-punned pointer will break strict-aliasing rules
We could address this [1], however despite ptrace.m4's claim:
# Needs to be tested in C++ mode, to detect whether we need to cast
# the first argument to enum __ptrace_request.
it appears that there's actually no need to test in C++ mode. Always
running the ptrace tests in C mode works just the same on GNU/Linux.
I remember experimenting with several different ways to handle the
original issue back then, and maybe that was needed in some other
attempt and then I didn't realize it ended up not really necessary.
Confirmed that this fixes the NetBSD 5.1 C++ build, and confirmed that
C and C++ builds on Fedora 23 are unaffected.

Make ftrace tests work with remote targets
When we build a shared library for testing, it is built differently
whether it is meant for the local system or a remote one. When it is
for the local system, the library is built with no SONAME. So when the
executable is built, roughly in this way:
$ gcc testfile.c /path/to/library.so
the executable will contain an absolute reference to the library. For
example:
$ readelf -a testsuite/gdb.python/py-shared | grep NEEDED
0x0000000000000001 (NEEDED) Shared library: [/home/emaisin/build/binutils-gdb/gdb/testsuite/gdb.python/py-shared-sl.sl]
When testing is done remotely, the absolute path obviously doesn't work.
Therefore, we build the library with an SONAME:
$ readelf -a testsuite/gdb.python/py-shared-sl.sl | grep SONAME
0x000000000000000e (SONAME) Library soname: [py-shared-sl.sl]
which ends up in the executable's NEEDED field:
$ readelf -a testsuite/gdb.python/py-shared | grep NEEDED
0x0000000000000001 (NEEDED) Shared library: [py-shared-sl.sl]
The executable and the library are then uploaded side-by-side on the
remote system. To allow the dynamic linker to find the shared library,
we have to add the special RPATH value $ORIGIN, which tells it to search
in the executable's directory:
$ readelf -a testsuite/gdb.python/py-shared | grep ORIGIN
0x000000000000000f (RPATH) Library rpath: [$ORIGIN]
The problem with the IPA library is that it doesn't have an SONAME,
making it very difficult to do testing on a remote board. When a
test executable is linked with it, it contains an absolute reference to
the library path. Therefore, unless the paths on the target are the
same as on the build system, it won't work.
To make it possible for tests using the IPA library to run test on
remote boards, I suggest adding an SONAME to libinproctrace.so. I don't
think it should be a big problem for users. All the libraries installed
on my system have an SONAME, so it should be fine if libinproctrace.so
does too.
As a consequence, native testing does not work anymore, since
executables do not contain the absolute path to the library anymore. To
keep them working, we can have gdb_load_shlibs copy the library to the
test directory when testing natively. That's done by modifying
gdb_load_shlibs. We also have to add RPATH=$ORIGIN to executables, even
when testing natively.
I think it's a good change in general, as it reduces the differences
between testing a native and a remote target. To further reduce those
differences, we can also always build test shared libraries with an
SONAME.
ftrace.exp and ftrace-lock.exp need to be modified slightly. The code
checks that the IPA library is loaded using the absolute path on the
build machine. That obviously doesn't work if the test is done
remotely, as the path will be different. I changed the tests to only
search for the library basename (e.g. libinproctrace.so).
gdb/gdbserver/ChangeLog:
* Makefile.in ($(IPA_LIB)): Set SONAME of the IPA lib.
gdb/testsuite/ChangeLog:
* gdb.trace/ftrace-lock.exp: Check for IPA basename instead of
absolute.
* gdb.trace/ftrace.exp: Likewise.
* lib/gdb.exp (gdb_compile): Set rpath $ORIGIN for non-remote
targets as well.
(gdb_compile_shlib): Set SONAME for non-remote targets as well.
(gdb_load_shlibs): Copy libraries to test directory when testing
natively. Only set solib-search-path if testing remotely.
* lib/mi-support.exp (mi_load_shlibs): Likewise.

gdbserver: Handle 'v' packet while processing qSymbol.
On powerpc64, qSymbol query may require gdb to read a function
descriptor, sending a vFile packet to gdbserver. Thus, we need
to handle 'v' packet in look_up_one_symbol.
vFile replies may be quite long, and require reallocating own_buf.
Since handle_v_requests assumes the buffer is the static global own_buf
from server.c and reallocates it, we need to make own_buf global and
use it from look_up_one_symbol instead of using our own auto variable.
I've also done the same change in relocate_instruction, just in case.
On gdb side, in remote_check_symbols, rs->buf may be clobbered by vFile
handling, yet we need its contents for the reply (the symbol name is
stored there). Allocate a new buffer instead.
This broke fast tracepoints on powerpc64, due to errors in reading IPA
symbols.
gdb/ChangeLog:
* remote.c (remote_check_symbols): Allocate own buffer for reply.
gdbserver/ChangeLog:
* remote-utils.c (look_up_one_symbol): Remove own_buf, handle 'v'
packets.
(relocate_instruction): Remove own_buf.
* server.c (own_buf): Make global.
(handle_v_requests): Make global.
* server.h (own_buf): New declaration.
(handle_v_requests): New prototype.

Set signal to 0 after enqueue_pending_signal
Today, we enqueue signal in linux_resume_one_lwp_throw, but set
variable 'signal' many lines below with the comment
/* Postpone any pending signal. It was enqueued above. */
signal = 0;
I feel difficult to associate code across many lines, and we should
move the code close to enqueue_pending_signal call. This is what
this patch does in general. After this change, variable 'signal'
is set to zero very early, so the 'signal' value in the following
debugging message makes no sense, so I remove it from the debugging
message. The function returns early if lwp->status_pending_p is
true, so 'signal' value in the debugging message doesn't matter,
AFAICS. Also, I move one debugging message several lines below to
make it close the real ptrace call,
if (debug_threads)
debug_printf ("Resuming lwp %ld (%s, signal %d, stop %s)\n",
lwpid_of (thread), step ? "step" : "continue", signal,
lwp->stop_expected ? "expected" : "not expected");
so that the debugging message can reflect what GDBserver does. This
is a code refactor and only debugging messages are affected.

when GDBserver steps over a thread, other threads have been suspended,
the "stepping" thread may create new thread, but GDBserver doesn't set
it suspend count to 1. When GDBserver unsuspend threads, the child's
suspend count goes to -1, and the assert is triggered. In fact, GDBserver
has already taken care of suspend count of new thread when GDBserver is
suspending all threads except the one GDBserver wants to step over by
https://sourceware.org/ml/gdb-patches/2015-07/msg00946.html
+ /* If we're suspending all threads, leave this one suspended
+ too. */
+ if (stopping_threads == STOPPING_AND_SUSPENDING_THREADS)
+ {
+ if (debug_threads)
+ debug_printf ("HEW: leaving child suspended\n");
+ child_lwp->suspended = 1;
+ }
but that is not enough, because new thread is still can be spawned in
the thread which is being stepped over. This patch extends the
condition that GDBserver set child's suspend count to one if it is
suspending threads or stepping over the thread.

gdbserver/s390: Enable high GPRs, VX, TDB with 31-bit gdbserver.
Currently, 31-bit gdbserver doesn't support collecting/supplying high
GPRs, VX registers, and TDB data. This is not much of a problem now,
since machines that have them usually have a 64-bit gdbserver that can
be used to debug 31-bit targets just fine. However, with fast
tracepoints, it's not possible to use a 64-bit gdbserver with a 31-bit
IPA (and thus a 31-bit target), so 31-bit gdbserver has to be used
for 31-bit targets. Thus, this patch is needed to allow collecting
high GPRs and VX registers on 31-bit targets via fast tracepoints.

[PR gdb/13808] gdb.trace: Pass tdesc selected in gdbserver to IPA.
If gdbserver and IPA are using different tdesc, they will disagree
about 'R' trace packet size. This results in mangled traces.
To make sure they pick the same tdesc, gdbserver pokes the tdesc
(specified as an index in a target-specific list) into a global
variable in IPA. In theory, IPA could find out the tdesc on its
own, but that may be complex (in particular, I don't know how to
tell whether we have LAST_BREAK on s390 without messing with ptrace),
and we'd have to duplicate the logic.
Tested on i386 and x86_64. On i386, it fixes two FAILs in ftrace.exp.
On x86_64, these failures have been KFAILed - one of them works now,
but the other now fails due to an unrelated reason (ugh).

[ARM] Fixup PC in software single step
When I exercise GDBserver software single step, I see the following
error, which has been already handled by GDB properly.
In GDBserver log, we can see, GDBserver tries to single step instruction
on 0xb6e0a6e4, and destination address is 0xffff0fe0,
stop pc is 0xb6e0a6e4
Writing f001f0e7 to 0xffff0fe0 in process 7132
Failed to insert breakpoint at 0xffff0fe0 (Input/output error).
Failed to insert breakpoint at 0xffff0fe0 (-1).
(gdb) disassemble __aeabi_read_tp,+8
Dump of assembler code from 0xb6e0a6e0 to 0xb6e0a6e8:
0xb6e0a6e0 <__aeabi_read_tp+0>: mvn r0, #61440 ; 0xf000
0xb6e0a6e4 <__aeabi_read_tp+4>: sub pc, r0, #31
however, it fails inserting breakpoint there. This problem has already
fixed by GDB, see comments in arm-linux-tdep.c:arm_linux_software_single_step
/* The Linux kernel offers some user-mode helpers in a high page. We can
not read this page (as of 2.6.23), and even if we could then we
couldn't set breakpoints in it, and even if we could then the atomic
operations would fail when interrupted. They are all called as
functions and return to the address in LR, so step to there
instead. */
so we need to do the same thing in GDB side as well. This patch adds
a new field fixup in arm_get_next_pcs_ops, so that we can fix up PC
for arm-linux target. In this way, both GDB and GDBserver can single
step instructions going to kernel helpers.

gdbserver: Remove tracepoint_action ops.
This patch removes 'ops' in tracepoint, and uses helper functions to
call action handler instead.
The object layout of tracepoint_action may differ in gdbserver and
inferior depend on the alignment rule of target ABI, so gdbserver cannot
simply copy the object from its memory to inferior memory.
For example,
struct collect_memory_action
{
struct tracepoint_action base;
{
#ifndef IN_PROCESS_AGENT
const struct tracepoint_action_ops *ops;
#if
- char type;
| }
| ULONGEST addr;
| ULONGEST len;
- int32_t basereg;
};
and on PowerPC,
Wihtout ops with ops
0 1 2 3 0 1 2 3
0 |type| PADDING... 0 |ops-------------|
4 ................. 4 |type|PADDING....|
8 |addr------------ 8 |addr-------------
c ----------------| c -----------------|
10 |len------------- 10 |len--------------
14 ----------------| 14 -----------------|
18 |basereg--------| 18 |basereg---------|
so we cannot directly copy the object.
In this patch, 'ops' is removed in order to make the objects identical.

[GDBserver] Check input interrupt after reading in a packet
GDBserver may read some packet together with '\003' in one go. We've
already checked '\003' first when reading packet by my patch,
Check input interrupt first when reading packet
https://sourceware.org/ml/gdb-patches/2016-01/msg00057.html
but if we don't check '\003' *after* each packet, the interrupt will
be processed next time GDBserver reads from the buffer, so that the
interrupt isn't processed in time. For example, GDB sends vCont;c and
interrupt (see gdb.base/interrupt-noterm.exp), we'll resume the
inferior and wait once packet vCont;c is seen. If we don't check the
interrupt character after vCont;c packet, interrupt character will stay
in the buffer unattended until GDBserver returns from the wait, which
may take a while. Note that since we've read '\003' from file
descriptor, SIGIO signal handler input_interrupt doesn't help either.
This issue can be exposed by hacking the end of getpkt like
@@ -1041,6 +1050,9 @@ getpkt (char *buf)
}
}
+ if (readchar_bufcnt > 0)
+ gdb_assert (*readchar_bufp != '\003');
+
return bp - buf;
}
and this can trigger internal error,

in my test setting, program is compiled in arm mode, but the glibc
is built in thumb mode, so when we do 'step' to step over syscall
instruction svc for SIGRETURN, GDB should set breakpoint for arm mode
in the program, even though the current program in glibc is in thumb
mode. Current GDB doesn't consider the case that the mode of program
SIGRETURN goes to can be different from current program mode.
In fact, GDB has taken care of this arm/thumb mode changes already,
see
/* Copy the value of next pc of sigreturn and rt_sigrturn into PC,
return 1. In addition, set IS_THUMB depending on whether we
will return to ARM or Thumb code. Return 0 if it is not a

the IS_THUMB setting is lost, so it is a regression.

Replace some $ARCH_{get,set}_pc with linux_{get,set}_pc_64bit
This patch is the follow-up of
https://sourceware.org/ml/gdb-patches/2016-01/msg00164.html to provide
linux_{get,set}_pc_64bit functions.
Rebuild GDBserver with tilegx-linux-gcc. Not tested.
I think about pc in Tile-GX a little bit. Looks current Tile-GX
supports debugging 32-bit program (multi-arch), but PC is always
64-bit. See this thread
https://sourceware.org/ml/gdb-patches/2013-02/msg00113.html
and GDBserver reads PC as 64-bit through ptrace. However, if
the inferior is 32-bit, the PC in the target description and
regcache is 32-bit, so only 32-bit contents are sent back GDB.
Anyway, Tile-GX GDBserver may have some problems here, but this
patch doesn't change anything.

Replace some $ARCH_{get,set}_pc with linux_{get,set}_pc_32bit
This patch adds a pair of new functions linux_get_pc_32bit and
linux_set_pc_32bit which get and set 32-bit register "pc" from
regcache. This function can be used some targets and these own
$ARCH_{get,set}_pc are replaced by linux_{get,set}_pc_32bit
respectively.
This patch touches many targets, but I only have arm board to
test and no regression. I also rebuilt nios2-linux GDBserver.
If it is right to go, I'll post the 64-bit counterpart later.

[ARM] Make thumb2_breakpoint static again
This patch makes thumb2_breakpoint static. When writing this patch,
I find the only reason we keep thumb2_breakpoint extern is that it
is used as an argument passed to arm_gdbserver_get_next_pcs. However,
field arm_thumb2_breakpoint is only used in a null check in
thumb_get_next_pcs_raw, so I wonder why do need to pass thumb2_breakpoint
to arm_gdbserver_get_next_pcs.
thumb2_breakpoint was added by Daniel Jacobowitz in order to support
single-step IT block
https://sourceware.org/ml/gdb-patches/2010-01/msg00624.html the logic
there was if we have 32-bit thumb-2 breakpoint defined, we can safely
single-step IT block, otherwise, we can't. Daniel didn't want to use
16-bit thumb BKPT instruction, because it triggers even on instruction
which should be executed. Secondly, using 16-bit thumb illegal
instruction on top of 32-bit thumb instruction may break the meaning of
original IT blocks, because the other 16-bit can be regarded as an
instruction. See more explanations from Daniel's kernel patch
http://www.spinics.net/lists/arm-kernel/msg80476.html
Let us back to this patch, GDB/GDBserver can safely single step
IT block if thumb2_breakpoint is defined, but the single step logic
doesn't have to know the thumb-2 breakpoint instruction. Only
breakpoint insertion mechanism decides to use which breakpoint
instruction. In the software single step code, instead of pass
thumb2_breakpoint, we can pass a boolean variable
has_thumb2_breakpoint indicate whether the target has thumb-2
breakpoint defined, which is equivalent to the original code.
Regression tested on arm-linux. No regression.

Check input interrupt first when reading packet
Hi,
I see timeout in one of several runs of random-signal.exp like this,
$ (set -e; while true; do make check RUNTESTFLAGS="--target_board=native-gdbserver random-signal.exp"; done)
In about every five runs, we can see a fail,
PASS: gdb.base/random-signal.exp: continue
^CFAIL: gdb.base/random-signal.exp: stop with control-c (timeout)
after some investigation, I find '\003' may be discarded by GDBserver when
it is expecting '$'. In GDB side, both normal packets and '\003' are sent
via function send, but GDBserver may receive them at any time, that is to
say, in the receive buffer in GDBserver, '\003' may appear before or after
normal packet. However, current GDBserver doesn't handle this case.
With this patch applied, I don't see this fail in multiple runs.
Although there is still timeout fail, that is a different problem, the
next patch will fix it.

[lynxos] gdbserver hangs when killing inferior from GDB
With any program under GDBserver control on LynxOS, killing
the program from the debugger (using the "kill" command) causes
GDBserver to properly kill the inferior but GDBserver then hangs.
This change of behavior occured after the following change was
applied:
commit f0ea042932e6922c90df3fd0001497d287b97677
Date: Mon Nov 30 16:05:27 2015 +0000
Subject: gdbserver: don't exit until GDB disconnects
One of the changes introduced by the commit above is that
process_serial_event no longer calls exit after handling
the vKill packet. Instead, what happens is that we wait
until captured_main finds that we no longer have any inferior
to debug, at which point it throws_quit. This (normal) exception
is then expected to propagate all the way to the exception handle
in function "main", which calls exit.
However, before the exception gets propagated, the cleanups
are first executed, and one of the cleanups in question is
detach_or_kill_for_exit_cleanup, which was put in place by
captured_main. detach_or_kill_for_exit_cleanup is basically
a wrapper around detach_or_kill_for_exit, which iterates
over all inferiors, and kills them all.
In our case, we have only one inferior, which we have already
killed during the handling for the "vKill" packet. Unfortunately,
we did not properly clean our internal data for that inferior up,
and so detach_or_kill_for_exit thinks that we still have one inferior,
and therefore tries to kill it. This results in lynx_kill being
called, doing the following:
lynx_ptrace (PTRACE_KILL, ptid, 0, 0, 0);
lynx_wait (ptid, &status, 0);
the_target->mourn (process);
The hang is caused by the call to lynx_wait, which waits for
an event from a process which does not exist...
This patch fixes the issue by enhancing lynx_mourn to clean
the threads and process list up.

* lynx-low.c (lynx_delete_thread_callback): New function.

Support software single step on ARM in GDBServer
This patch teaches GDBServer how to software single step on ARM
linux by sharing code with GDB.
The arm_get_next_pcs function in GDB is now shared with GDBServer. So
that GDBServer can use the function to return the possible addresses of
the next PC.
A proper shared context was also needed so that we could share the code,
this context is described in the arm_get_next_pcs structure.

Support Z0 packet in AArch64 multi-arch debugging
In commit 6085d6f6, Z0 packet is disabled in aarch64 GDBserver if
the inferior is 32-bit or there may be multiple inferiors, because
Z0 packet isn't supported for arm then. Recently, Z0 packet
is supported in arm target, so we don't have such limitation in
aarch64 GDBserver, that is to say, aarch64 GDBserver can use Z0
packet in multi-arch/multi-inferior debugging when the inferior's
arch is arm.
Part of this patch is to revert 6085d6f6, and the rest of the patch
is to move some breakpoint related arm_* functions into
linux-aarch32-low.c in order to share them between arm and aarch64.
This patch is regression tested on aarch64-linux for debugging both
aarch64 programs and arm programs respectively.

Remove too simple breakpoint_reinsert_addr implementations.
This patch removes too simple implementations of the breakpoint_reinsert_addr
operation.
The only reason to keep them around was to support thread events when
PTRACE_EVENT_CLONE was not present but this support has been removed in a
previous patch.
No regressions, tested on ubuntu 14.04 ARMv7 and x86.
With gdbserver-{native,extended} / { -marm -mthumb }
Also compilation was tested on aarch64, bfin, cris, crisv32,
m32r, mips, nios2, ppc, s390, sparc, tic6x, tile, xtensa.

Remove support for thread events without PTRACE_EVENT_CLONE in GDBServer.
This patch removes support for thread events if PTRACE_EVENT_CLONE is not
supported in GDBServer.
Before, on systems that did not support PTRACE_EVENT_CLONE, both GDB and
GDBServer coordinated with libthread_db.so to insert breakpoints at magic
locations in libpthread.so, in order to break at thread creation and thread
death.
Simple software single stepping support was implemented to step over these
breakpoints in case there was no hardware single stepping support. However,
these simple software single stepping implementations were not fit for any other
use as discussed in :
https://sourceware.org/ml/gdb-patches/2015-04/msg01110.html
These too simple implementations conflict with ongoing work to make proper
implementations of software single stepping in GDBServer.
The problem is that if some implementations are correct and others are not and
only there for the thread magic breakpoint, we can't enable features based
solely software single step support since some would be broken.
To keep the incorrect implementations and allow the new proper ones at the same
time we would need to implement fallback code and it quickly becomes ugly and
confusing with multiple checks for legacy software single step or proper
software single step.
However, PTRACE_EVENT_CLONE was first introduced in Linux 2.5.46,
released in November 2002.
So I think it's reasonable to just remove support for kernels that don't support
PTRACE_EVENT_CLONE, and sidestep the libthread_db breakpoints issues entirely.
This thread on the mailling list discusses the issue :

Refactor queries for hardware and software single stepping support in GDBServer.
Before this patch there was only one call: can_hardware_single_step. Its
implementation was a check on breakpoint_reinsert_addr if NULL it assumed
that the target could hardware single step.
This patch prepares for the case where this is not true anymore.
In order to improve software single stepping in GDBServer the
breakpoint_reinsert_addr operation of targets that had a very simple
software implementation used only for stepping over thread creation events
will be removed.
This will create a case where a target does not support hardware single
step and has the operation breakpoint_reinsert_addr set to NULL, thus
can_hardware_single_step needs to be implemented another way.
A new target operation supports_hardware_single_step is introduced and is
to return true if the target does support such a feature, support for the
feature is manually hardcoded.
Note that the hardware single step support was enabled as per the current
behavior, I did not check if tile for example really has ptrace singlestep
support but since the current implementation assumed it had, I kept it
that way.

Fix instruction skipping when using software single step in GDBServer
Without this patch, when doing a software single step, with for example
a conditional breakpoint, gdbserver would wrongly avance the pc of
breakpoint_len and skips an instruction.
This is due to gdbserver assuming that it's hardware single stepping.
When it resumes from the breakpoint address it expects the trap to be
caused by ptrace and if it's rather caused by a software breakpoint
it assumes this is a permanent breakpoint and that it needs to skip
over it.
However when software single stepping, this breakpoint is legitimate as
it's the reinsert breakpoint gdbserver has put in place to break at
the next instruction. Thus gdbserver wrongly advances the pc and skips
an instruction.
This patch fixes this behavior so that gdbserver checks if it is a
reinsert breakpoint from software single stepping. If it is it won't
advance the pc. And if there's no reinsert breakpoint there we assume
then that it's a permanent breakpoint and advance the pc.
Here's a commented log of what would happen before and after the fix on
gdbserver :
/* Here there is a conditional breakpoint at 0x10428 that needs to be
stepped over. */
Need step over [LWP 11204]? yes, found breakpoint at 0x10428
...
/* e7f001f0 is a breakpoint instruction on arm
Here gdbserver writes the software breakpoint we would like to hit
*/
Writing e7f001f0 to 0x0001042c in process 11204
...
Resuming lwp 11220 (continue, signal 0, stop not expected)
pending reinsert at 0x10428
stop pc is 00010428
continue from pc 0x10428
...
/* Here gdbserver hit the software breakpoint that was in place
for the step over */
stop pc is 0001042c
pc is 0x1042c
step-over for LWP 11220.11220 executed software breakpoint
Finished step over.
Could not find fast tracepoint jump at 0x10428 in list (reinserting).
/* Here gdbserver writes back the original instruction */
Writing e50b3008 to 0x0001042c in process 11220
Step-over finished.
Need step over [LWP 11220]? No
/* Here because gdbserver assumes this is a permenant breakpoint it advances
the pc of breakpoint_len, in this case 4 bytes, so we have just skipped
the instruction that was written back here :
Writing e50b3008 to 0x0001042c in process 11220
*/
stop pc is 00010430
pc is 0x10430
Need step over [LWP 11220]? No, no breakpoint found at 0x10430
Proceeding, no step-over needed
proceed_one_lwp: lwp 11220
stop pc is 00010430
This patch fixes this situation and we get the right behavior :
Writing e50b3008 to 0x0001042c in process 11245
Hit a gdbserver breakpoint.
Hit a gdbserver breakpoint.
Step-over finished.
proceeding all threads.
Need step over [LWP 11245]? No
stop pc is 0001042c
pc is 0x1042c
Need step over [LWP 11245]? No, no breakpoint found at 0x1042c
Proceeding, no step-over needed
proceed_one_lwp: lwp 11245
stop pc is 0001042c
pc is 0x1042c
Resuming lwp 11245 (continue, signal 0, stop not expected)
stop pc is 0001042c
continue from pc 0x1042c
It also works if the value at 0x0001042c is a permanent breakpoint.
If so gdbserver will finish the step over, remove the reinserted breakpoint,
resume at that location and on the next SIGTRAP gdbserver will trigger
the advance PC condition as reinsert_breakpoint_inserted_here will be false.
I also tested this against bp-permanent.exp on arm (with a work in progress
software single step patchset) without any regressions.
It's also tested against x86 bp-permanent.exp without any regression.
So both software and hardware single step are tested.
No regressions on Ubuntu 14.04 on ARMv7 and x86.

Remote thread create/exit events
When testing with "maint set target-non-stop on", a few
threading-related tests expose an issue that requires new RSP packets.
Say there are 3 threads running, 1-3. If GDB tries to stop thread 1,
2 and 3, and then waits for their stops, but meanwhile say, thread 2
exits, GDB hangs forever waiting for a stop for thread 2 that won't
ever happen.
This patch fixes the issue by adding support for thread exit events to
the protocol. However, we don't want these always enabled, as they're
useless most of the time, and would slow down remote debugging. So I
made it so that GDB can enable/disable them, and then made gdb do that
around the cases that need it, which currently is only
infrun.c:stop_all_threads.
In turn, if we have thread exit events, then the extra "thread x
exited" traffic slows down attach-many-short-lived-threads.exp enough
that gdb has trouble keeping up with new threads that are spawned
while gdb tries to stop existing ones. To fix that I added support
for the counterpart thread created events too. Enabling those when we
try to stop threads ensures that new threads never get a chance to
themselves start new threads, killing the race.

gdbserver resume_stop handling bug
Running attach-many-short-lived-threads.exp with the extended-remote
board with "maint set target-non-stop on" times out -- the attach
never completes. Enabling infrun debug logs, we see that GDB is stuck
stopping all threads:
infrun: target_wait (-1.0.0, status) =
infrun: 1639.22213.0 [Thread 1639.22213],
infrun: status->kind = stopped, signal = GDB_SIGNAL_0

infrun: Thread 1639.22219 not executing
infrun: Thread 1639.1639 not executing
** HANG HERE **
GDB is waiting for the stop replies of any of those "already stopping"
threads. Take 22253 for example. On the gdbserver logs we see:
...
resume_stop request for LWP 22253
stopping LWP 22253
Sending sigstop to lwp 22253
linux_resume done
...
and:
my_waitpid (-1, 0x40000001)
my_waitpid (-1, 0x80000001): status(3057f), 22253
LWFE: waitpid(-1, ...) returned 22253, ERRNO-OK
LLW: waitpid 22253 received Trace/breakpoint trap (stopped)
pc is 0x3615ef4ce1
HEW: Got clone event from LWP 22253, new child is LWP 22259
but from here on, we never see any other event for LWP 22253. In
particular, we never see the expected SIGSTOP (from "Sending sigstop"
above). The issue is that linux_resume_stopped_resumed_lwps never
re-resumes the 22253 after the clone event.

[LynxOS] GDBserver crash debugging threaded program
This crash is observable by debugging a threaded program on LynxOS.
On the GDB side, this is what we would see:
% gdb q
(gdb) target remote machine:4444
(gdb) break q.adb:6
(gdb) cont
[gdb hits breakpoint]
(gdb) cont
Remote connection closed <<<--- expected: [Inferior 1 (Remote target) exited normally]
On the gdbserver side, which was launched as usual:
% gdbserver --once :4444 q
Segmentation fault (core dumped)
Ooops!
The problem happens while GDB is trying to handle the thread termination
event of the thread that hit the breakpoint. It started happening after
the following change was made:
commit 96e7a1eb6d09fda9e22e112e35e7d0085a8f4fd0
Date: Fri Oct 16 11:08:38 2015 -0400
Subject: gdbserver: Reset current_thread when the thread is removed.
Reset current_thread and make sure 'remove_process' is used
after all associated threads have been removed first.
More precisely:
. GDBserver receives the execution-resume order;
. lynx-low resumes it succesfully, and then relies on lynx_wait_1
to wait for the next event;
. We quickly receive one, which lynx_wait_1 analyzes to be
a "thread exit" event, and therefore does...
case SIGTHREADEXIT:
remove_thread (find_thread_ptid (new_ptid));
lynx_continue (new_ptid);
goto retry;
=> remove_thread causes current_thread to be set to NULL...
(that's the recent change mentioned above)
=> ... which causes problems during lynx_continue, because
it calls lynx_resume, which calls regcache_invalidate,
which unfortunately assumes that CURRENT_THREAD is not NULL:
void
regcache_invalidate (void)
{
/* Only update the threads of the current process. */
SEGV!--> int pid = ptid_get_pid (current_thread->entry.id);
find_inferior (&all_threads, regcache_invalidate_one, &pid);
}
Since the problem at hand is caused by trying to figure out which
inferior to reset the regcache for, and since lynx_resume actually
had that info, this patch fixes the problem by introducing a new
routine called regcache_invalidate_pid, which invalidates the cache
of the given pid; and then modifies lynx_resume use that new routine
rather than relying on regcache_invalidate to invalidate the regcache
of the expected inferior.
gdb/gdbserver/ChangeLog:
* regcache.h (regcache_invalidate_pid): Add declaration.
* regcache.c (regcache_invalidate_pid): New function, extracted
from regcache_invalidate.
(regcache_invalidate): Reimplement using regcache_invalidate_pid.
Add trivial documentation comment.
* lynx-low.c: Use regcache_invalidate_pid instead of
regcache_invalidate.

gdbserver: Fix qSupported:xmlRegisters=i386;UnknownFeature+ handling
The target_process_qsupported method is called for each qSupported
feature that the common code does not recognize. The only current
implementation, for x86 Linux (x86_linux_process_qsupported), assumes
that it either is called with the "xmlRegisters=i386" feature, or that
it is isn't called at all, indicating the connected GDB predates x86
XML descriptions.
That's a bad assumption however. If GDB sends in a new/unknown (to
core gdbserver) feature after "xmlRegisters=i386", say, something like
qSupported:xmlRegisters=i386;UnknownFeature+, then when
target_process_qsupported is called for "UnknownFeature+",
x86_linux_process_qsupported clears the 'use_xml' global and calls
x86_linux_update_xmltarget, and gdbserver ends up _not_ reporting a
XML description...
This commit changes the target_process_qsupported API to instead pass
down a vector of unprocessed qSupported features in one go.
(There's an early call to target_process_qsupported(NULL) that
indicates "starting qSupported processing". There's no matching call
to mark the end of processing, though. I first fixed this by passing
(char *)-1 to indicate that, and adjusted the x86 backend to only
clear 'use_xml' when qSupported processing starts, and then only call
x86_linux_update_xmltarget() when (char *)-1 was passed. However, I
wasn't that happy with the hack and came up this alternative version.)

Add the target_ops needed for software breakpoints in GDBServer.
This patch is in preparation for software breakpoints on ARM linux. It
refactors breakpoint and breakpoint_len into breakpoint_kind_from_pc and
sw_breakpoint_from kind to prepare the case where we have multiple types of
breakpoints.
Kind is the type of breakpoint (hardware or software) to be inserted, usually it
is the lenght of the software breakpoint but can be something else depending on
the target.
This patch introduces the linux_target_ops breakpoint_kind_from_pc and
sw_breakpoint_from_kind.
breakpoint_kind_from_pc returns the breakpoint kind and adjusts the PC to the
real memory location in case a flag was present in the PC. E.g the instruction
mode on ARM.
sw_breakpoint_from_kind returns the software breakpoint for this kind as a
string of bytes, the length of the breakpoint is adjusted for the breakpoint's
size in memory.
For targets that have only one kind of breakpoint, the default value 0 is
returned by linux_breakpoint_kind_from_pc so that not all targets need to
implement the breakpoint_kind_from_pc operation.
No regressions, tested on Ubuntu 14.04 on ARMv7 and x86
With gdbserver-{native,extended} / { -marm -mthumb }
Also since the target_ops have been changed compilation was tested on
affected archs namely : aarch64, arm, bfin, cris, crisv32, m32r,
m68k, mips, nios2, ppc, s390, sparc, tic6x, tile, x86, steins.

aarch64 multi-arch part 6: HW breakpoint on unaligned address
Nowadays, both aarch64 GDB and linux kernel assumes that address for
setting breakpoint should be 4-byte aligned. However that is not true
after we support multi-arch, because thumb instruction can be at 2-byte
aligned address. Patch http://lists.infradead.org/pipermail/linux-arm-kernel/2015-October/375141.html
to linux kernel is to teach kernel to handle 2-byte aligned address for
HW breakpoint, while this patch is to teach aarch64 GDB handle 2-byte
aligned address.
First of all, we call gdbarch_breakpoint_from_pc to get the instruction
length rather than using hard-coded 4. Secondly, in GDBserver, we set
length back to 2 if it is 3, because GDB encode 3 in it to indicate it
is a 32-bit thumb breakpoint. Then we relax the address alignment
check from 4-byte aligned to 2-byte aligned.
This patch enables some tests (such as gdb.base/break-idempotent.exp,
gdb.base/cond-eval-mode.exp, gdb.base/watchpoint-reuse-slot.exp,) and
fixes many fails (such as gdb.base/hbreak2.exp) when the program is
compiled in thumb mode on aarch64.
Regression tested on aarch64-linux, both native and gdbserver. This
is the last patch of multi-arch work.

Support displaced stepping in aarch64-linux
This patch is to support displaced stepping in aarch64-linux. A
visitor is implemented for displaced stepping, and used to record
information to fixup pc after displaced stepping if needed. Some
emit_* functions are converted to macros, and moved to
arch/aarch64-insn.{c,h} so that they can be shared.

Add some more casts (1/2)
Note: I needed to split this patch in two, otherwise it's too big for
the mailing list.
This patch adds explicit casts to situations where a void pointer is
assigned to a pointer to the "real" type. Building in C++ mode requires
those assignments to use an explicit cast. This includes, for example:
- callback arguments (cleanups, comparison functions, ...)
- data attached to some object (objfile, program space, etc) in the form
of a void pointer
- "user data" passed to some function
This patch comes from the commit "(mostly) auto-generated patch to insert
casts needed for C++", taken from Pedro's C++ branch.
Only files built on x86 with --enable-targets=all are modified, so the
native files for other arches will need to be dealt with separately.
I built-tested this with --enable-targets=all and reg-tested. To my
surprise, a test case (selftest.exp) had to be adjusted.
Here's the ChangeLog entry. Again, this was relatively quick to make
despite the length, thanks to David Malcom's script, although I don't
believe it's very useful information in that particular case...

Implement target_emit_ops
This patch implements compiling agent expressions to native code for
AArch64. This allows us to compile conditions set on fast tracepoints.
The compiled function has the following prologue:
High *------------------------------------------------------*
| LR |
| FP | <- FP
| x1 (ULONGEST *value) |
| x0 (unsigned char *regs) |
Low *------------------------------------------------------*
We save the function's argument on the stack as well as the return
address and the frame pointer. We then set the current frame pointer to
point to the previous one.
The generated code for the expression will freely update the stack
pointer so we use the frame pointer to refer to `*value' and `*regs'.
`*value' needs to be accessed in the epilogue of the function, in order
to set it to whatever is on top of the stack. `*regs' needs to be passed
down to the `gdb_agent_get_raw_reg' function with the `reg' operation.

Add support for fast tracepoints
This patch adds support for fast tracepoints for aarch64-linux. With this
implementation, a tracepoint can only be placed in a +/- 128MB range of
the jump pad. This is due to the unconditional branch instruction
being limited to a (26 bit << 2) offset from the current PC.
Three target operations are implemented:
- target_install_fast_tracepoint_jump_pad
Building the jump pad the biggest change of this patch. We need to add
functions to emit all instructions needed to save and restore the
current state when the tracepoint is hit. As well as implementing a
lock and creating a collecting_t object identifying the current thread.
Steps performed by the jump pad:
* Save the current state on the stack.
* Push a collecting_t object on the stack. We read the special
tpidr_el0 system register to get the thread ID.
* Spin-lock on the shared memory location of all tracing threads. We
write the address of our collecting_t object there once we have the
lock.
* Call gdb_collect.
* Release the lock.
* Restore the state.
* Execute the replaced instruction which will have been relocated.
* Jump back to the program.
- target_get_thread_area
As implemented in ps_get_thread_area, target_get_thread_area uses ptrace
to fetch the NT_ARM_TLS register. At the architecture level, NT_ARM_TLS
represents the tpidr_el0 system register.
So this ptrace call (if lwpid is the current thread):
~~~
ptrace (PTRACE_GETREGSET, lwpid, NT_ARM_TLS, &iovec);
~~~
Is equivalent to the following instruction:
~~~
msr x0, tpidr_el0
~~~
This instruction is used when creating the collecting_t object that
GDBserver can read to know if a given thread is currently tracing.
So target_get_thread_area must get the same thread IDs as what the jump
pad writes into its collecting_t object.
- target_get_min_fast_tracepoint_insn_len
This just returns 4.

Support single step by arch or target
Nowadays, GDB only knows whether architecture supports hardware single
step or software single step (through gdbarch hook software_single_step),
and for a given instruction or instruction sequence, GDB knows how to
do single step (hardware or software). However, GDB doesn't know whether
the target supports hardware single step. It is possible that the
architecture doesn't support hardware single step, such as arm, but
the target supports, such as simulator. This was discussed in this
thread https://www.sourceware.org/ml/gdb/2009-12/msg00033.html before.
I encounter this problem for aarch64 multi-arch support. When aarch64
debugs arm program, gdbarch is arm, so software single step is still
used. However, the underneath linux kernel does support hardware
single step, so IWBN to use it.
This patch is to add a new target_ops hook to_can_do_single_step, and
only use it in arm_linux_software_single_step to decide whether or not
to use hardware single step. On the native aarch64 linux target, 1 is
returned. On other targets, -1 is returned. On the remote target, if
the target supports s and S actions in the vCont? reply, then target
can do single step. However, old GDBserver will send s and S in the
reply to vCont?, which will confuse new GDB. For example, old GDBserver
on arm-linux will send s and S in the reply to vCont?, but it doesn't
support hardware single step. On the other hand, new GDBserver, on
arm-linux for example, will not send s and S in the reply to vCont?,
but old GDB thinks it doesn't support vCont packet at all. In order
to address this problem, I add a new qSupported feature vContSupported,
which indicates GDB wants to know the supported actions in the reply
to vCont?, and qSupported response contains vContSupported if the
stub is able tell supported vCont actions in the reply of vCont?.
If the patched GDB talks with patched GDBserver on x86, the RSP traffic
is like this:
-> $qSupported:...+;vContSupported+
<- ...+;vContSupported+
...
-> $vCont?
<- vCont;c;C;t;s;S;r
then, GDB knows the stub can do single step, and may stop using software
single step even the architecture doesn't support hardware single step.
If the patched GDB talks with patched GDBserver on arm, the last vCont?
reply will become:
<- vCont;c;C;t
GDB thinks the target doesn't support single step, so it will use software
single step.
If the patched GDB talks with unpatched GDBserver, the RSP traffic is like
this:
-> $qSupported:...+;vContSupported+
<- ...+
...
-> $vCont?
<- vCont;c;C;t;s;S;r
although GDBserver returns s and S, GDB still thinks GDBserver may not
support single step because it doesn't support vContSupported.
If the unpatched GDB talks with patched GDBserver on x86, the RSP traffic
is like:
-> $qSupported:...+;
<- ...+;vContSupported+
...
-> $vCont?
<- vCont;c;C;t;s;S;r
Since GDB doesn't sent vContSupported in the qSupported feature, GDBserver
sends s and S regardless of the support of hardware single step.

aarch64 multi-arch support (part 2): siginfo fixup
This patch is to fixup the siginfo_t when aarch64 gdb or gdbserver
read from or write to the arm inferior. It is to convert the
"struct siginfo_t" between aarch64 and arm, which is quite mechanical.

Extended-remote follow-exec
This patch implements support for exec events on extended-remote Linux
targets. Follow-exec-mode and rerun behave as expected. Catchpoints and
test updates are implemented in subsequent patches.
This patch was derived from a patch posted last October:
https://sourceware.org/ml/gdb-patches/2014-10/msg00877.html.
It was originally based on some work done by Luis Machado in 2013.
IMPLEMENTATION
----------------
Exec events are enabled via ptrace options.
When an exec event is detected by gdbserver, the existing process
data, along with all its associated lwp and thread data, is deleted
and replaced by data for a new single-threaded process. The new
process data is initialized with the appropriate parts of the state
of the execing process. This approach takes care of several potential
pitfalls, including:
* deleting the data for an execing non-leader thread before any
wait/sigsuspend occurs
* correctly initializing the architecture of the execed process
We then report the exec event using a new RSP stop reason, "exec".
When GDB receives an "exec" event, it saves the status in the event
structure's target_waitstatus field, like what is done for remote fork
events. Because the original and execed programs may have different
architectures, we skip parsing the section of the stop reply packet
that contains register data. The register data will be retrieved
later after the inferior's architecture has been set up by
infrun.c:follow_exec.
At that point the exec event is handled by the existing event handling
in GDB. However, a few changes were necessary so that
infrun.c:follow_exec could accommodate the remote target.
* Where follow-exec-mode "new" is handled, we now call
add_inferior_with_spaces instead of add_inferior with separate calls
to set up the program and address spaces. The motivation for this
is that add_inferior_with_spaces also sets up the initial architecture
for the inferior, which is needed later by target_find_description
when it calls target_gdbarch.
* We call a new target function, target_follow_exec. This function
allows us to store the execd_pathname in the inferior, instead of
using the static string remote_exec_file from remote.c. The static
string didn't work for follow-exec-mode "new", since once you switched
to the execed program, the original remote exec-file was lost. The
execd_pathname is now stored in the inferior's program space as a
REGISTRY field. All of the requisite mechanisms for this are
defined in remote.c.

[aarch64] Check region OK for HW watchpoint in GDBserver
Nowadays, if user requests HW watchpoint to monitor a large memory area
or unaligned area, aarch64 GDB will split into multiple aligned areas,
and use multiple debugging registers to watch them. However, the
registers are not updated in a transaction way. GDBserver doesn't revert
updates in previous iterations if some debugging registers fail to update
due to some reason, like no free debugging registers available, in the
latter iteration. For example, if we have a char buf[34], and watch buf
in gdb,
(gdb) watch buf
Hardware watchpoint 2: buf
(gdb) c

four debugging registers can not monitor 34-byte long area, so the last
iteration of updating debugging register state fails but previous
iterations succeed. This makes GDB think no HW watchpoint is inserted
but some debugging registers are used.
This problem was exposed by "watch buf" gdb.base/watchpoint.exp with
aarch64 GDBserver debugging arm 32-bit program. The buf is 30-byte long
but 4-byte aligned, and four debugging registers can't cover 34-byte
(extend 4 bytes to be 8-byte aligned) area. However, this problem
does exist on non-multi-arch debugging scenario as well.
This patch moves code in aarch64_linux_region_ok_for_hw_watchpoint to
aarch64_linux_region_ok_for_watchpoint in nat/aarch64-linux-hw-point.c.
Then, checks with aarch64_linux_region_ok_for_watchpoint, like what we
are doing in GDB. If the region is OK, call aarch64_handle_watchpoint.
Regression tested on aarch64 with both 64-bit program and 32-bit
program. Some fails in gdb.base/watchpoint.exp are fixed.

Replace some xmalloc-family functions with XNEW-family ones
This patch is part of the make-gdb-buildable-in-C++ effort. The idea is
to change some calls to the xmalloc family of functions to calls to the
equivalents in the XNEW family. This avoids adding an explicit cast, so
it keeps the code a bit more readable. Some of them also map relatively
well to a C++ equivalent (XNEW (struct foo) -> new foo), so it will be
possible to do scripted replacements if needed.
I only changed calls that were obviously allocating memory for one or
multiple "objects". Allocation of variable sizes (such as strings or
buffer handling) will be for later (and won't use XNEW).
- xmalloc (sizeof (struct foo)) -> XNEW (struct foo)
- xmalloc (num * sizeof (struct foo)) -> XNEWVEC (struct foo, num)
- xcalloc (1, sizeof (struct foo)) -> XCNEW (struct foo)
- xcalloc (num, sizeof (struct foo)) -> XCNEWVEC (struct foo, num)
- xrealloc (p, num * sizeof (struct foo) -> XRESIZEVEC (struct foo, p, num)
- obstack_alloc (ob, sizeof (struct foo)) -> XOBNEW (ob, struct foo)
- obstack_alloc (ob, num * sizeof (struct foo)) -> XOBNEWVEC (ob, struct foo, num)
- alloca (sizeof (struct foo)) -> XALLOCA (struct foo)
- alloca (num * sizeof (struct foo)) -> XALLOCAVEC (struct foo, num)
Some instances of xmalloc followed by memset to zero the buffer were
replaced by XCNEW or XCNEWVEC.
I regtested on x86-64, Ubuntu 14.04, but the patch touches many
architecture-specific files. For those I'll have to rely on the
buildbot or people complaining that I broke their gdb.

* ax.c (gdb_parse_agent_expr): Replace xmalloc-family function with
|
|
|
|
|
the XNEW-family equivalent.
|
Replace some xmalloc-family functions with XNEW-family ones
This patch is part of the make-gdb-buildable-in-C++ effort. The idea is
to change some calls to the xmalloc family of functions to calls to the
equivalents in the XNEW family. This avoids adding an explicit cast, so
it keeps the code a bit more readable. Some of them also map relatively
well to a C++ equivalent (XNEW (struct foo) -> new foo), so it will be
possible to do scripted replacements if needed.
I only changed calls that were obviously allocating memory for one or
multiple "objects". Allocation of variable sizes (such as strings or
buffer handling) will be for later (and won't use XNEW).
- xmalloc (sizeof (struct foo)) -> XNEW (struct foo)
- xmalloc (num * sizeof (struct foo)) -> XNEWVEC (struct foo, num)
- xcalloc (1, sizeof (struct foo)) -> XCNEW (struct foo)
- xcalloc (num, sizeof (struct foo)) -> XCNEWVEC (struct foo, num)
- xrealloc (p, num * sizeof (struct foo) -> XRESIZEVEC (struct foo, p, num)
- obstack_alloc (ob, sizeof (struct foo)) -> XOBNEW (ob, struct foo)
- obstack_alloc (ob, num * sizeof (struct foo)) -> XOBNEWVEC (ob, struct foo, num)
- alloca (sizeof (struct foo)) -> XALLOCA (struct foo)
- alloca (num * sizeof (struct foo)) -> XALLOCAVEC (struct foo, num)
Some instances of xmalloc followed by memset to zero the buffer were
replaced by XCNEW or XCNEWVEC.
I regtested on x86-64, Ubuntu 14.04, but the patch touches many
architecture-specific files. For those I'll have to rely on the
buildbot or people complaining that I broke their gdb.

Clearly this means that a thread pushed a stop reply in the event
queue, and then before GDB confused the event, the whole process died,
along with its thread. But the pending thread event was left
dangling. When GDB fetched that event, gdbserver looked up the
corresponding thread, but found NULL; not expecting this, gdbserver
crashes when it tries to read this thread's registers.

gdbserver: don't pick a random thread if the current thread dies
In all-stop mode, if the current thread disappears while stopping all
threads, gdbserver calls set_desired_thread(0) ['0' means "I want the
continue thread"] which just picks the first thread in the list.
This looks like a dangerous thing to do. GDBserver continues
processing whatever it was doing, but to the wrong thread. If
debugging more than one process, we may even pick the wrong process.
Instead, GDBserver should detect the situation and bail out of
whatever is was doing.
The backends used to pay attention to the set 'cont_thread' (the Hc
thread, used in the old way to resume threads, before vCont), but all
such 'cont_thread' checks have been eliminated meanwhile. The
remaining implicit dependencies that I found on there being a selected
thread in the backends are in the Ctrl-C handling, which some backends
use as thread to send a signal to. Even that seems to me to be better
handled by always using the first thread in the list or by using the
signal_pid PID.
In order to make this a systematic approach, I'm making
set_desired_thread never fallback to a random thread, and instead end
up with current_thread == NULL, like already done in non-stop mode.
Then I updated all callers to handle the situation.
I stumbled on this while fixing other bugs exposed by
gdb.threads/fork-plus-threads.exp test. The problems I saw were fixed
in a different way, but in any case, I think the potential for
problems is more or less obvious, and the resulting code looks a bit
less magical to me.
Tested on x86-64 Fedora 20, w/ native-extended-gdbserver board.

gdbserver: Fix non-stop / fork / step-over issues
Ref: https://sourceware.org/ml/gdb-patches/2015-07/msg00868.html
This adds a test that has a multithreaded program have several threads
continuously fork, while another thread continuously steps over a
breakpoint.
This exposes several intertwined issues, which this patch addresses:
- When we're stopping and suspending threads, some thread may fork,
and we missed setting its suspend count to 1, like we do when a new
clone/thread is detected. When we next unsuspend threads, the fork
child's suspend count goes below 0, which is bogus and fails an
assertion.
- If a step-over is cancelled because a signal arrives, but then gdb
is not interested in the signal, we pass the signal straight back
to the inferior. However, we miss that we need to re-increment the
suspend counts of all other threads that had been paused for the
step-over. As a result, other threads indefinitely end up stuck
stopped.
- If a detach request comes in just while gdbserver is handling a
step-over (in the test at hand, this is GDB detaching the fork
child), gdbserver internal errors in stabilize_thread's helpers,
which assert that all thread's suspend counts are 0 (otherwise we
wouldn't be able to move threads out of the jump pads). The
suspend counts aren't 0 while a step-over is in progress, because
all threads but the one stepping past the breakpoint must remain
paused until the step-over finishes and the breakpoint can be
reinserted.
- Occasionally, we see "BAD - reinserting but not stepping." being
output (from within linux_resume_one_lwp_throw). That was because
GDB pokes memory while gdbserver is busy with a step-over, and that
suspends threads, and then re-resumes them with proceed_one_lwp,
which missed another reason to tell linux_resume_one_lwp that the
thread should be set back to stepping.
- In a couple places, we were resuming threads that are meant to be
suspended. E.g., when a vCont;c/s request for thread B comes in
just while gdbserver is stepping thread A past a breakpoint. The
resume for thread B must be deferred until the step-over finishes.
- The test runs with both "set detach-on-fork" on and off. When off,
it exercises the case of GDB detaching the fork child explicitly.
When on, it exercises the case of gdb resuming the child
explicitly. In the "off" case, gdb seems to exponentially become
slower as new inferiors are created. This is _very_ noticeable as
with only 100 inferiors gdb is crawling already, which makes the
test take quite a bit to run. For that reason, I've disabled the
"off" variant for now.

Disable Z0 packet on aarch64 on multi-arch debugging
In multi-arch debugging, if GDB sends Z0 packet, GDBserver should be
able to do several things below:
- choose the right breakpoint instruction to insert according to the
information available, such as 'kind' in Z0 packet and address,
- choose the right breakpoint instruction to check memory writes and
validate inserted memory breakpoint
- be aware of different breakpoint instructions in $ARCH_breakpoint_at.
unfortunately GDBserver can't do them now. Although x86 GDBserver
supports multi-arch, it doesn't need to support them above because
breakpoint instruction on i686 and x86_64 is the same. However,
breakpoint instructions on aarch64 and arm (arm mode, thumb1, and thumb2)
are different.
I tried to teach aarch64 GDBserver backend to be really
multi-arch-capable in the following ways,
- linux_low_target return the right breakpoint instruction according to
the 'kind' in Z0 packet, and insert_memory_breakpoint can do the right
thing.
- once breakpoint is inserted, the breakpoint data and length is recorded
in each breakpoint object, so that validate_breakpoint and
check_mem_write can get the right breakpoint instruction from each
breakpoint object, rather than from global variable breakpoint_data.
- linux_low_target needs another hook function for pc increment after
hitting a breakpoint.
- let set_breakpoint_at, which is widely used for tracepoint, use the
'default' breakpoint instruction. We can always use aarch64 breakpoint
instruction since arm doesn't support tracepoint yet.
looks it is not a small piece of work, so I decide to disable Z0 packet
on multi-arch, which means aarch64 GDBserver only supports Z0 packet
if it is started to debug only one process (extended protocol is not
used) and process target description is 64-bit.

C++: dlsym casts in gdb/linux-thread-db.c and gdb/gdbserver/thread-db.c
Implicit void * -> function pointer conversion doesn't work in C++, so
in C++, we need to cast the result of dlsym. This adds a few typedefs
and macros that make this easy. GDBserver's version already had the
CHK macro, so I added it to GDB too.
Tested on x86_64 Fedora 20, native and gdbserver.

C++: handle glibc's ptrace(enum __ptrace_request, ...)
Building in C++ mode issues ~40 warnings like this:
../../src/gdb/linux-nat.c: In function ‘int linux_handle_extended_wait(lwp_info*, int, int)’:
../../src/gdb/linux-nat.c:2016:51: warning: invalid conversion from ‘int’ to ‘__ptrace_request’ [-fpermissive]
ptrace (PTRACE_GETEVENTMSG, pid, 0, &new_pid);
The issue is that in glibc, ptrace's first parameter is an enum.
That's not a problem if we pick the PTRACE_XXX requests from
sys/ptrace.h, as those will be values of the corresponding enum.
However, we have fallback definitions for PTRACE_XXX symbols when the
system headers miss them (such as PTRACE_GETEVENTMSG above), and those
are plain integer constants. E.g., nat/linux-ptrace.h:
#define PTRACE_GETEVENTMSG 0x4201
One idea would be to fix this by defining those fallbacks like:
-#define PTRACE_GETEVENTMSG 0x4201
+#define PTRACE_GETEVENTMSG ((enum __ptrace_request) 0x4201)
However, while glibc's ptrace uses enum __ptrace_request for first
parameter:
extern long int ptrace (enum __ptrace_request __request, ...) __THROW;
other libc's, like e.g., Android's bionic do not -- in that case, the
first parameter is int:
long ptrace(int request, pid_t pid, void * addr, void * data);
So the fix I came up is to make configure/ptrace.m4 also detect the
type of the ptrace's first parameter and defin PTRACE_TYPE_ARG1, as
already does the for parameters 3-4, and then simply wrap ptrace with
a macro that casts the first argument to the detected type. (I'm
leaving adding a nicer wrapper for when we drop building in C).
While this adds the wrapper, GNU/Linux files won't use it until the
next patch, which makes all native GNU/Linux files include
gdb_ptrace.h.

Initialise target descrption after skipping extra traps for --wrapper
Nowadays, when --wrapper is used, GDBserver skips extra traps/stops
in the wrapper program, and stops at the first instruction of the
program to be debugged. However, GDBserver created target description
in the first stop of inferior, and the executable of the inferior
is the wrapper program rather than the program to be debugged. In
this way, the target description can be wrong if the architectures
of wrapper program and program to be debugged are different. This
is shown by some fails in gdb.server/wrapper.exp on buildbot.
We are testing i686-linux GDB (Fedora-i686) on an x86_64-linux box
(fedora-x86-64-4) in buildbot, such configuration causes fails in
gdb.server/wrapper.exp like this:
spawn /home/gdb-buildbot-2/fedora-x86-64-4/fedora-i686/build/gdb/testsuite/../../gdb/gdbserver/gdbserver --once --wrapper env TEST=1 -- :2346 /home/gdb-buildbot-2/fedora-x86-64-4/fedora-i686/build/gdb/testsuite/outputs/gdb.server/wrapper/wrapper
Process /home/gdb-buildbot-2/fedora-x86-64-4/fedora-i686/build/gdb/testsuite/outputs/gdb.server/wrapper/wrapper created; pid = 8795
Can't debug 64-bit process with 32-bit GDBserver
Exiting
target remote localhost:2346
localhost:2346: Connection timed out.
(gdb) FAIL: gdb.server/wrapper.exp: setting breakpoint at marker
See https://sourceware.org/ml/gdb-testers/2015-q3/msg01541.html
In this case, program to be debugged ("wrapper") is 32-bit but wrapper
program ("/usr/bin/env") is 64-bit, so GDBserver gets the 64-bit
target description instead of 32-bit.
The root cause of this problem is that GDBserver creates target
description too early, and the rationale of fix could be creating
target description once the GDBserver skips extra traps and inferior
stops at the first instruction of the program we want to debug. IOW,
when GDBserver skips extra traps, the inferior's tdesc is NULL, and
mywait and its callees shouldn't use inferior's tdesc, so in this
patch, we skip code that requires register access, see changes in
linux_resume_one_lwp_throw and need_step_over_p.
In linux_low_filter_event, if target description isn't initialised and
GDBserver attached the process, we create target description immediately,
because GDBserver don't have to skip extra traps for attach, IOW, it
makes no sense to use --attach and --wrapper together. Otherwise, the
process is launched by GDBserver, we keep the status pending, and return.
After GDBserver skipped extra traps in start_inferior, we call a
target_ops hook arch_setup to initialise target description there.

Move common aarch64 HW breakpoint/watchpoint code to nat/
When I look at test fails related to watchpoint on aarch64-linux,
I find there are some code duplicates between GDB and GDBserver.
This patch is to move some of them to a nat/aarch64-linux-hw-point.{h,c}.
The only change I do is about the dr_changed_t typedef, which was
ULONGEST in GDB and 'unsigned long long' in GDBserver. Each bit
of dr_changed_t represents a status of each HW breakpoint or
watchpoint register, and the max number of HW breakpoint or watchpoint
registers is 16, so the width of 'unsigned long long' is sufficient.

The following patch...

|
| libthread_db.so calls symbols in the client (GDB), through the
| proc-service interface. These routines must have extern "C" linkage
| so their symbol names are not mangled when GDB is built as a C++
| program. On the GDBserver side, we were missing fallback declarations for
| all these symbols.

... added a number of declarations which do not compile when cross-
compiling GDBserver on arm-android. The problem comes from type
prfpregset_t not being declared:
/[...]/gdbserver/gdb_proc_service.h:98:47:
error: unknown type name 'prfpregset_t'
After searching through the includes of the install we have,
I could not find that type being declared anywhere. So I did
the same as for prgregset_t, and created the typedef if the
type isn't declared.

Arch-specific remote follow fork
This patch implements the architecture-specific pieces of follow-fork
for remote and extended-remote Linux targets, which in the current
implementation copyies the parent's debug register state into the new
child's data structures. This is required for x86, arm, aarch64, and
mips.
This follows the native implementation as closely as possible by
implementing a new linux_target_ops function 'new_fork', which is
analogous to 'linux_nat_new_fork' in linux-nat.c. In gdbserver, the debug
registers are stored in the process list, instead of an
architecture-specific list, so the function arguments are process_info
pointers instead of an lwp_info and a pid as in the native implementation.
In the MIPS implementation the debug register mirror is stored differently
from x86, ARM, and aarch64, so instead of doing a simple structure assignment
I had to clone the list of watchpoint structures.
Tested using gdb.threads/watchpoint-fork.exp on x86, and ran manual tests
on a MIPS board and an ARM board. Aarch64 hasn't been tested.
gdb/gdbserver/ChangeLog:
* linux-aarch64-low.c (aarch64_linux_new_fork): New function.
(the_low_target) <new_fork>: Initialize new member.

Extended-remote Linux follow fork
This patch implements basic support for follow-fork and detach-on-fork on
extended-remote Linux targets. Only 'fork' is supported in this patch;
'vfork' support is added n a subsequent patch. This patch depends on
the previous patches in the patch series.
Sufficient extended-remote functionality has been implemented here to pass
gdb.base/multi-forks.exp, as well as gdb.base/foll-fork.exp with the
catchpoint tests commented out. Some other fork tests fail with this
patch because it doesn't provide the architecture support needed for
watchpoint inheritance or fork catchpoints.
The implementation follows the same general structure as for the native
implementation as much as possible.
This implementation includes:
* enabling fork events in linux-low.c in initialize_low and
linux_enable_extended_features
* handling fork events in gdbserver/linux-low.c:handle_extended_wait
- when a fork event occurs in gdbserver, we must do the full creation
of the new process, thread, lwp, and breakpoint lists. This is
required whether or not the new child is destined to be
detached-on-fork, because GDB will make target calls that require all
the structures. In particular we need the breakpoint lists in order
to remove the breakpoints from a detaching child. If we are not
detaching the child we will need all these structures anyway.
- as part of this event handling we store the target_waitstatus in a new
member of the parent lwp_info structure, 'waitstatus'. This
is used to store extended event information for reporting to GDB.
- handle_extended_wait is given a return value, denoting whether the
handled event should be reported to GDB. Previously it had only
handled clone events, which were never reported.
* using a new predicate in gdbserver to control handling of the fork event
(and eventually all extended events) in linux_wait_1. The predicate,
extended_event_reported, checks a target_waitstatus.kind for an
extended ptrace event.
* implementing a new RSP 'T' Stop Reply Packet stop reason: "fork", in
gdbserver/remote-utils.c and remote.c.
* implementing new target and RSP support for target_follow_fork with
target extended-remote. (The RSP components were actually defined in
patch 1, but they see their first use here).
- remote target routine remote_follow_fork, which just sends the 'D;pid'
detach packet to detach the new fork child cleanly. We can't just
call target_detach because the data structures for the forked child
have not been allocated on the host side.
Tested on x64 Ubuntu Lucid, native, remote, extended-remote.

Identify remote fork event support
This patch implements a mechanism for GDB to determine whether fork
events are supported in gdbserver. This is a preparatory patch for
remote fork and exec event support.
Two new RSP packets are defined to represent fork and vfork event
support. These packets are used just like PACKET_multiprocess_feature
to denote whether the corresponding event is supported. GDB sends
fork-events+ and vfork-events+ to gdbserver to inquire about fork
event support. If the response enables these packets, then GDB
knows that gdbserver supports the corresponding events and will
enable them.
Target functions used to query for support are included along with
each new packet.
In order for gdbserver to know whether the events are supported at the
point where the qSupported packet arrives, the code in nat/linux-ptrace.c
had to be reorganized. Previously it would test for fork/exec event
support, then enable the events using the pid of the inferior. When the
qSupported packet arrives there may not be an inferior. So the mechanism
was split into two parts: a function that checks whether the events are
supported, called when gdbserver starts up, and another that enables the
events when the inferior stops for the first time.
Another gdbserver change was to add some global variables similar to
multi_process, one per new packet. These are used to control whether
the corresponding fork events are enabled. If GDB does not inquire
about the event support in the qSupported packet, then gdbserver will
not set these "report the event" flags. If the flags are not set, the
events are ignored like they were in the past. Thus, gdbserver will
never send fork event notification to an older GDB that doesn't
recognize fork events.
Tested on Ubuntu x64, native/remote/extended-remote, and as part of
subsequent patches in the series.

[gdbserver] Disable conditional breakpoints on no-hardware-single-step targets
GDBserver steps over breakpoint if the condition is false, but if target
doesn't support hardware single step, the step over is very simple, if
not incorrect, in linux-arm-low.c:
/* We only place breakpoints in empty marker functions, and thread locking
is outside of the function. So rather than importing software single-step,
we can just run until exit. */
static CORE_ADDR
arm_reinsert_addr (void)
{
struct regcache *regcache = get_thread_regcache (current_thread, 1);
unsigned long pc;
collect_register_by_name (regcache, "lr", &pc);
return pc;
}
and linux-mips-low.c does the same. GDBserver sets a breakpoint at the
return address of the current function, resume and wait the program hits
the breakpoint in order to achieve "breakpoint step over". What if
program hits other user breakponits during this "step over"?
It is worse if the arm/thumb interworking is considered. Nowadays,
GDBserver arm backend unconditionally inserts arm breakpoint,
/* Define an ARM-mode breakpoint; we only set breakpoints in the C
library, which is most likely to be ARM. If the kernel supports
clone events, we will never insert a breakpoint, so even a Thumb
C library will work; so will mixing EABI/non-EABI gdbserver and
application. */
(const unsigned char *) &arm_breakpoint,
(const unsigned char *) &arm_eabi_breakpoint,
note that the comments are no longer valid as C library can be compiled
in thumb mode.
When GDBserver steps over a breakpoint in arm mode function, which
returns to thumb mode, GDBserver will insert arm mode breakpoint by
mistake and the program will crash. GDBserver alone is unable to
determine the arm/thumb mode given a PC address. See how GDB does
it in arm-tdep.c:arm_pc_is_thumb.
After thinking about how to teach GDBserver inserting right breakpoint
(arm or thumb) for a while, I reconsider it from a different direction
that it may be unreasonable to run target-side conditional breakpoint for
targets without hardware single step. Pedro also pointed this out here
https://sourceware.org/ml/gdb-patches/2015-04/msg00337.html
This patch is to add a new target_ops hook
supports_conditional_breakpoints, and only reply
";ConditionalBreakpoints+" if it is true. On linux targets,
supports_conditional_breakpoints returns true if target has hardware
single step, on other targets, (win32, lynx, nto, spu), set it to NULL,
because conditional breakpoint is a linux-specific feature.

gdbserver gnu/linux: stepping over breakpoint
Hi,
I see the following error on arm linux gdbserver,
continue^M
Continuing.^M
../../../binutils-gdb/gdb/gdbserver/linux-arm-low.c:458: A problem internal to GDBserver has been detected.^M
raw_bkpt_type_to_arm_hwbp_type: unhandled raw type^M

(gdb) FAIL: gdb.base/cond-eval-mode.exp: hbreak: continue
After we make GDBserver handling Zx/zx packet idempotent,
[PATCH 3/3] [GDBserver] Make Zx/zx packet handling idempotent.
https://sourceware.org/ml/gdb-patches/2014-04/msg00480.html
> Now removal/insertion of all kinds of breakpoints/watchpoints, either
> internal, or from GDB, always go through the target methods.
GDBserver handles all kinds of breakpoints/watchpoints through target
methods. However, some target backends, such as arm, don't support Z0
packet but need software breakpoint to do breakpoint stepping over in
linux-low.c:start_step_over,
if (can_hardware_single_step ())
{
step = 1;
}
else
{
CORE_ADDR raddr = (*the_low_target.breakpoint_reinsert_addr) ();
set_reinsert_breakpoint (raddr);
step = 0;
}
a software breakpoint is requested to the backend, and the error is
triggered. This problem should affect targets having
breakpoint_reinsert_addr hooked.
Instead of handling memory breakpoint in these affected linux backend,
this patch handles memory breakpoint in linux_{insert,remove}_point,
that, if memory breakpoint is requested, call
{insert,remove}_memory_breakpoint respectively. Then, it becomes
unnecessary to handle memory breakpoint for linux x86 backend, so
this patch removes the code there.
This patch is tested with GDBserver on x86_64-linux and arm-linux
(-marm, -mthumb). Note that there are still some fails in
gdb.base/cond-eval-mode.exp with -mthumb, because GDBserver doesn't
know how to select the correct breakpoint instruction according to
the arm-or-thumb-mode of requested address. This is a separate
issue, anyway.

GDBServer: give more complete usage information
--attach/--multi are currently only mentioned on the usage info first
lines, the meaning of PROG is completely absent and the COMM text does
not mention '-/stdio'.
A few options are missing:
. --disable-randomization / --no-disable-randomization is not mentioned.
Although the manual has a comment saying these are superceded by
QDisableRandomization, that only makes sense for "run" in
extended-remote mode. When we start gdbserver passing it a PROG,
--disable-randomization / --no-disable-randomization do take effect.
So I think we should document these.
. We show --debug / --remote-debug, so might as well show --disable-packet too.
GDB's --help has this "For more information, consult the GDB manual"
blurb that is missing in GDBserver's --help.
Then shuffle things around a bit into "Operating modes", "Other
options" and "Debug options" sections, similarly to GDB's --help
structure.
Before:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
$ ./gdbserver/gdbserver --help
Usage: gdbserver [OPTIONS] COMM PROG [ARGS ...]
gdbserver [OPTIONS] --attach COMM PID
gdbserver [OPTIONS] --multi COMM
COMM may either be a tty device (for serial debugging), or
HOST:PORT to listen for a TCP connection.
Options:
--debug Enable general debugging output.
--debug-format=opt1[,opt2,...]
Specify extra content in debugging output.
Options:
all
none
timestamp
--remote-debug Enable remote protocol debugging output.
--version Display version information and exit.
--wrapper WRAPPER -- Run WRAPPER to start new programs.
--once Exit after the first connection has closed.
Report bugs to "<http://www.gnu.org/software/gdb/bugs/>".
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
After:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
$ ./gdbserver/gdbserver --help
Usage: gdbserver [OPTIONS] COMM PROG [ARGS ...]
gdbserver [OPTIONS] --attach COMM PID
gdbserver [OPTIONS] --multi COMM
COMM may either be a tty device (for serial debugging),
HOST:PORT to listen for a TCP connection, or '-' or 'stdio' to use
stdin/stdout of gdbserver.
PROG is the executable program. ARGS are arguments passed to inferior.
PID is the process ID to attach to, when --attach is specified.
Operating modes:
--attach Attach to running process PID.
--multi Start server without a specific program, and
only quit when explicitly commanded.
--once Exit after the first connection has closed.
--help Print this message and then exit.
--version Display version information and exit.
Other options:
--wrapper WRAPPER -- Run WRAPPER to start new programs.
--disable-randomization
Run PROG with address space randomization disabled.
--no-disable-randomization
Don't disable address space randomization when
starting PROG.
Debug options:
--debug Enable general debugging output.
--debug-format=opt1[,opt2,...]
Specify extra content in debugging output.
Options:
all
none
timestamp
--remote-debug Enable remote protocol debugging output.
--disable-packet=opt1[,opt2,...]
Disable support for RSP packets or features.
Options:
vCont, Tthread, qC, qfThreadInfo and
threads (disable all threading packets).
For more information, consult the GDB manual (available as on-line
info or a printed manual).
Report bugs to "<http://www.gnu.org/software/gdb/bugs/>".

Fix race exposed by gdb.threads/killed.exp
On GNU/Linux, this test sometimes FAILs like this:
(gdb) run
Starting program: /home/pedro/gdb/mygit/build/gdb/testsuite/gdb.threads/killed
[Thread debugging using libthread_db enabled]
Using host libthread_db library "/lib64/libthread_db.so.1".
ptrace: No such process.
(gdb)
Program terminated with signal SIGKILL, Killed.
The program no longer exists.
FAIL: gdb.threads/killed.exp: run program to completion (timeout)
Note the suspicious "No such process" line (that's errno==ESRCH).
Adding debug output we see:

Program terminated with signal SIGKILL, Killed.
The program no longer exists.
infrun: stop_waiting
FAIL: gdb.threads/killed.exp: run program to completion (timeout)
The issue is that here:
RSRL: resuming stopped-resumed LWP LWP 18465 at 0x3b36af4b51: step=0
RSRL: resuming stopped-resumed LWP LWP 18461 at 0x3b36af4b51: step=0
The first line shows we had just resumed LWP 18465, which does:
void *
child_func (void *dummy)
{
kill (pid, SIGKILL);
exit (1);
}
So if the kernel manages to schedule that thread fast enough, the
process may be killed before GDB has a chance to resume LWP 18461.
GDBserver has code at the tail end of linux_resume_one_lwp to cope
with this:
~~~
ptrace (step ? PTRACE_SINGLESTEP : PTRACE_CONT, lwpid_of (thread),
(PTRACE_TYPE_ARG3) 0,
/* Coerce to a uintptr_t first to avoid potential gcc warning
of coercing an 8 byte integer to a 4 byte pointer. */
(PTRACE_TYPE_ARG4) (uintptr_t) signal);
current_thread = saved_thread;
if (errno)
{
/* ESRCH from ptrace either means that the thread was already
running (an error) or that it is gone (a race condition). If
it's gone, we will get a notification the next time we wait,
so we can ignore the error. We could differentiate these
two, but it's tricky without waiting; the thread still exists
as a zombie, so sending it signal 0 would succeed. So just
ignore ESRCH. */
if (errno == ESRCH)
return;
perror_with_name ("ptrace");
}
~~~
However, that's not a complete fix, because between starting to handle
the resume request and getting that PTRACE_CONTINUE, we run other
ptrace calls that can also fail with ESRCH, and that end up throwing
an error (with perror_with_name).
In the case above, I indeed sometimes see resume_stopped_resumed_lwps
fail in the registers read:
resume_stopped_resumed_lwps (struct lwp_info *lp, void *data)
{
...
CORE_ADDR pc = regcache_read_pc (regcache);
Or e.g., in 32-bit mode, i386_linux_resume has several calls that can
throw too.
Whether to ignore ptrace errors or not depends on context that is only
available somewhere up the call chain. So the fix is to let ptrace
errors throw as they do today, and wrap the resume request in a
TRY/CATCH that swallows it iff the lwp that we were trying to resume
is no longer ptrace-stopped.

gdbserver/Linux: unbreak thread event randomization
Wanting to make sure the new continue-pending-status.exp test tests
both cases of threads 2 and 3 reporting an event, I added counters to
the test, to make it FAIL if events for both threads aren't seen.
Assuming a well behaved backend, and given a reasonable number of
iterations, it should PASS.
However, running that against GNU/Linux gdbserver, I found that
surprisingly, that FAILed. GDBserver always reported the breakpoint
hit for the same thread.
Turns out that I broke gdbserver's thread event randomization
recently, with git commit 582511be ([gdbserver] linux-low.c: better
starvation avoidance, handle non-stop mode too). In that commit I
missed that the thread structure also has a status_pending_p field...
The end result was that count_events_callback always returns 0, and
then if no thread is stepping, select_event_lwp always returns the
event thread. IOW, no randomization is happening at all. Quite
curious how all the other changes in that patch were sufficient to fix
non-stop-fair-events.exp anyway even with that broken.
Tested on x86_64 Fedora 20, native and gdbserver.

Fix struct sockaddr/sockaddr_in/sockaddr_un strict aliasing violations
Building gdbserver in C++ mode shows:
gdb/gdbserver/tracepoint.c: In function ‘void* gdb_agent_helper_thread(void*)’:
gdb/gdbserver/tracepoint.c:7190:47: error: cannot convert ‘sockaddr_un*’ to ‘sockaddr*’ for argument ‘2’ to ‘int accept(int, sockaddr*, socklen_t*)’
fd = accept (listen_fd, &sockaddr, &tmp);
A few places in the tree already have an explicit cast to struct
sockaddr *, but that's a strict aliasing violation. Instead of
propagating invalid code, fix this by using a union instead.

Split TRY_CATCH into TRY + CATCH
This patch splits the TRY_CATCH macro into three, so that we go from
this:
~~~
volatile gdb_exception ex;
TRY_CATCH (ex, RETURN_MASK_ERROR)
{
}
if (ex.reason < 0)
{
}
~~~
to this:
~~~
TRY
{
}
CATCH (ex, RETURN_MASK_ERROR)
{
}
END_CATCH
~~~
Thus, we'll be getting rid of the local volatile exception object, and
declaring the caught exception in the catch block.
This allows reimplementing TRY/CATCH in terms of C++ exceptions when
building in C++ mode, while still allowing to build GDB in C mode
(using setjmp/longjmp), as a transition step.
TBC, after this patch, is it _not_ valid to have code between the TRY
and the CATCH blocks, like:
TRY
{
}
// some code here.
CATCH (ex, RETURN_MASK_ERROR)
{
}
END_CATCH
Just like it isn't valid to do that with C++'s native try/catch.
By switching to creating the exception object inside the CATCH block
scope, we can get rid of all the explicitly allocated volatile
exception objects all over the tree, and map the CATCH block more
directly to C++'s catch blocks.
The majority of the TRY_CATCH -> TRY+CATCH+END_CATCH conversion was
done with a script, rerun from scratch at every rebase, no manual
editing involved. After the mechanical conversion, a few places
needed manual intervention, to fix preexisting cases where we were
using the exception object outside of the TRY_CATCH block, and cases
where we were using "else" after a 'if (ex.reason) < 0)' [a CATCH
after this patch]. The result was folded into this patch so that GDB
still builds at each incremental step.
END_CATCH is necessary for two reasons:
First, because we name the exception object in the CATCH block, which
requires creating a scope, which in turn must be closed somewhere.
Declaring the exception variable in the initializer field of a for
block, like:
#define CATCH(EXCEPTION, mask) \
for (struct gdb_exception EXCEPTION; \
exceptions_state_mc_catch (&EXCEPTION, MASK); \
EXCEPTION = exception_none)
would avoid needing END_CATCH, but alas, in C mode, we build with C90,
which doesn't allow mixed declarations and code.
Second, because when TRY/CATCH are wired to real C++ try/catch, as
long as we need to handle cleanup chains, even if there's no CATCH
block that wants to catch the exception, we need for stop at every
frame in the unwind chain and run cleanups, then rethrow. That will
be done in END_CATCH.
After we require C++, we'll still need TRY/CATCH/END_CATCH until
cleanups are completely phased out -- TRY/CATCH in C++ mode will
save/restore the current cleanup chain, like in C mode, and END_CATCH
catches otherwise uncaugh exceptions, runs cleanups and rethrows, so
that C++ cleanups and exceptions can coexist.
IMO, this still makes the TRY/CATCH code look a bit more like a
newcomer would expect, so IMO worth it even if we weren't considering
C++.

proc-service, extern "C"
libthread_db.so calls symbols in the client (GDB), through the
proc-service interface. These routines must have extern "C" linkage
so their symbol names are not mangled when GDB is built as a C++
program. On the GDBserver side, we were missing fallback declarations for
all these symbols.

Make functions and variables exported by the IPA be extern "C"
Functions and variables that are exported by the IPA DSO (that
GDBserver needs to look up) should have "C" mangling, thus be declared
with extern "C".
Function and variable declarations need the extern "C" marker, but
variable definitions can't be marked extern, so the patch splits
IP_AGENT_EXPORT into three.
Building in C++ mode revealed that a few variables were missing
IP_AGENT_EXPORT, thus the IPA has been broken when stripped, even in C
mode... So this ends being a bug fix as well.

Add --enable-build-with-cxx configure switch
This new option, disabled by default for now, allows specifying
whether to build GDB, GDBserver, and friends with a C++ (98/03)
compiler.
The name of the switch should be familiar to those who followed GCC's
own C++ conversion process.
. Adding -fpermissive to COMPILER in C++ mode (see the new
build-with-cxx.m4 file) makes errors like these be warnings instead:
gdb/infrun.c:6597:1: error: initializing argument 1 of ‘void sig_print_info(gdb_signal)’ [-fpermissive]
sig_print_info (enum gdb_signal oursig)
^
gdb/infrun.c: In function ‘void do_restore_infcall_suspend_state_cleanup(void*)’:
gdb/infrun.c:7164:39: error: invalid conversion from ‘void*’ to ‘infcall_suspend_state*’ [-fpermissive]
restore_infcall_suspend_state (state);
^
so that the compiler carries on compiling the file. -Werror still
catches the warnings, so nothing is lost, only our lifes are made
easier by concentrating on getting other more important things out of
the way first.
There's no way to quiet those warnings. Until they're all fixed, when
building in C++ mode, -Werror is disabled by default.
. Adding -Wno-narrowing suppresses thousands of instances of this warning:
gdb/arm-linux-tdep.c:439:1: error: narrowing conversion of ‘-1’ from ‘int’ to ‘ULONGEST {aka long unsigned int}’ inside { } is ill-formed in C++11 [-Werror=narrowing]
gdb/arm-linux-tdep.c:439:1: error: narrowing conversion of ‘-1l’ from ‘LONGEST {aka long int}’ to ‘ULONGEST {aka long unsigned int}’ inside { } is ill-formed in C++11 [-Werror=narrowing]
gdb/arm-linux-tdep.c:450:1: error: narrowing conversion of ‘-1’ from ‘int’ to ‘ULONGEST {aka long unsigned int}’ inside { } is ill-formed in C++11 [-Werror=narrowing]
We can defer handling those until we target C++11.
. Adding -Wno-sign-compare suppresses thousands of instances of this warning:
gdb/linux-record.c:1763:32: warning: comparison between signed and unsigned integer expressions [-Wsign-compare]
if (tmpulongest == tdep->fcntl_F_GETLK64)
^
. Adding -Wno-write-strings suppresses thousands of instances of this warning:
gdb/mi/mi-cmd-var.c: In function ‘void mi_cmd_var_show_attributes(char*, char**, int)’:
gdb/mi/mi-cmd-var.c:514:12: warning: deprecated conversion from string constant to ‘char*’ [-Wwrite-strings]
attstr = "editable";
^
gdb/mi/mi-cmd-var.c:516:12: warning: deprecated conversion from string constant to ‘char*’ [-Wwrite-strings]
attstr = "noneditable";
^
For now, it's best to hide these warnings from view until we're
'-fpermissive'-clean, and can thus start building with -Werror.
The C compiler has always managed to build working GDBs with these
issues in the code, so a C++ compiler should too.

Create libiberty.m4, have GDB and GDBserver use it
Converting GDB to be a C++ program, I stumbled on 'basename' issues,
like:
src/gdb/../include/ansidecl.h:169:64: error: new declaration ‘char* basename(const char*)’
/usr/include/string.h:597:26: error: ambiguates old declaration ‘const char* basename(const char*)’
which I believe led to this bit in gold's configure.ac:
dnl We have to check these in C, not C++, because autoconf generates
dnl tests which have no type information, and current glibc provides
dnl multiple declarations of functions like basename when compiling
dnl with C++.
AC_CHECK_DECLS([basename, ffs, asprintf, vasprintf, snprintf, vsnprintf, strverscmp])
These checks IIUC intend to generate all the HAVE_DECL_FOO symbols
that libiberty.h and ansidecl.h check.
GDB is missing these checks currently, which results in the conflict
shown above.
This adds an m4 file that both GDB and GDBserver's configury use to
pull in the autoconf checks that libiberty clients needs done in order
to use these libiberty.h/ansidecl.h.

gdbserver: 64-bit kernel / 32-inferior, syscall restarting
$ make check RUNTESTFLAGS="--target_board=native-gdbserver/-m32 clone-thread_db.exp"
gdb.log shows:
Running target native-gdbserver/-m32
...
clone-thread_db: src/gdb/testsuite/gdb.threads/clone-thread_db.c:57: thread_fn: Assertion `res != -1' failed.
...
(gdb) FAIL: gdb.threads/clone-thread_db.exp: continue to end
That was waitpid returning -1 / EINTR. We don't see that when testing
with unix/-m32 (native debugging). Turns out to be that when
debugging a 32-bit inferior, a 64-bit GDBserver is reading/writing
$orig_eax from/to the wrong ptrace register buffer offset. When
gdbserver is 64-bit, the ptrace register buffer is in 64-bit layout,
so the register is found at "ORIG_EAX * 8", not at "ORIG_EAX * 4".
Fixes these with --target_board=native-gdbserver/-m32 on x86_64 Fedora 20:

GNU/Linux: Stop using libthread_db/td_ta_thr_iter
TL;DR - GDB can hang if something refreshes the thread list out of the
target while the target is running. GDB hangs inside td_ta_thr_iter.
The fix is to not use that libthread_db function anymore.
Long version:
Running the testsuite against my all-stop-on-top-of-non-stop series is
still exposing latent non-stop bugs.
I was originally seeing this with the multi-create.exp test, back when
we were still using libthread_db thread event breakpoints. The
all-stop-on-top-of-non-stop series forces a thread list refresh each
time GDB needs to start stepping over a breakpoint (to pause all
threads). That test hits the thread event breakpoint often, resulting
in a bunch of step-over operations, thus a bunch of thread list
refreshes while some threads in the target are running.
The commit adds a real non-stop mode test that triggers the issue,
based on multi-create.exp, that does an explicit "info threads" when a
breakpoint is hit. IOW, it does the same things the as-ns series was
doing when testing multi-create.exp.
The bug is a race, so it unfortunately takes several runs for the test
to trigger it. In fact, even when setting the test running in a loop,
it sometimes takes several minutes for it to trigger for me.
The race is related to libthread_db's td_ta_thr_iter. This is
libthread_db's entry point for walking the thread list of the
inferior.
Sometimes, when GDB refreshes the thread list from the target,
libthread_db's td_ta_thr_iter can somehow see glibc's thread list as a
cycle, and get stuck in an infinite loop.
The issue is that when a thread exits, its thread control structure in
glibc is moved from a "used" list to a "cache" list. These lists are
simply circular linked lists where the "next/prev" pointers are
embedded in the thread control structure itself. The "next" pointer
of the last element of the list points back to the list's sentinel
"head". There's only one set of "next/prev" pointers for both lists;
thus a thread can only be in one of the lists at a time, not in both
simultaneously.
So when thread C exits, simplifying, the following happens. A-C are
threads. stack_used and stack_cache are the list's heads.
Before:
stack_used -> A -> B -> C -> (&stack_used)
stack_cache -> (&stack_cache)
After:
stack_used -> A -> B -> (&stack_used)
stack_cache -> C -> (&stack_cache)
td_ta_thr_iter starts by iterating at the list's head's next, and
iterates until it sees a thread whose next pointer points to the
list's head again. Thus in the before case above, C's next points to
stack_used, indicating end of list. In the same case, the stack_cache
list is empty.
For each thread being iterated, td_ta_thr_iter reads the whole thread
object out of the inferior. This includes the thread's "next"
pointer.
In the scenario above, it may happen that td_ta_thr_iter is iterating
thread B and has already read B's thread structure just before thread
C exits and its control structure moves to the cached list.
Now, recall that td_ta_thr_iter is running in the context of GDB, and
there's no locking between GDB and the inferior. From it's local copy
of B, td_ta_thr_iter believes that the next thread after B is thread
C, so it happilly continues iterating to C, a thread that has already
exited, and is now in the stack cache list.
After iterating C, td_ta_thr_iter finds the stack_cache head, which
because it is not stack_used, td_ta_thr_iter assumes it's just another
thread. After this, unless the reverse race triggers, GDB gets stuck
in td_ta_thr_iter forever walking the stack_cache list, as no thread
in thatlist has a next pointer that points back to stack_used (the
terminating condition).
Before fully understanding the issue, I tried adding cycle detection
to GDB's td_ta_thr_iter callback. However, td_ta_thr_iter skips
calling the callback in some cases, which means that it's possible
that the callback isn't called at all, making it impossible for GDB to
break the loop. I did manage to get GDB stuck in that state more than
once.
Fortunately, we can avoid the issue altogether. We don't really need
td_ta_thr_iter for live debugging nowadays, given PTRACE_EVENT_CLONE.
We already know how to map and lwp id to a thread id without iterating
(thread_from_lwp), so use that more.

fix gdbserver/linux-low'c's pending status handling
Another fix I'm working made schedlock.exp fail with gdbserver
frequently. Looking deeper, it turns out to be a pre-existing bug.
status_pending_p_callback is filtering out LWPs incorrectly. The
result is that that sometimes status_pending_p_callback returns a
pending event for an LWP that isn't expected, and then GDBserver gets
very confused.
E.g,. when doing a step-over, linux_wait_for_event is called with a
particular LWP's ptid, meaning events for all other LWPs should be
left pending, but here we see it retuning an event for some other LWP:
linux_wait_1: [<all threads>]
step_over_bkpt set [LWP 29577.29577], doing a blocking wait <--------
my_waitpid (-1, 0x40000001)
my_waitpid (-1, 0x80000001): status(57f), 0
LWFE: waitpid(-1, ...) returned 0, ERRNO-OK
pc is 0x4007a0

libthread_db: Skip attaching to terminated and joined threads
I wrote a test that attaches to a program that constantly spawns
short-lived threads, which exposed several issues. This is one of
them.
On GNU/Linux, attaching to a multi-threaded program sometimes prints
out warnings like:
...
[New LWP 20700]
warning: unable to open /proc file '/proc/-1/status'
[New LWP 20850]
[New LWP 21019]
...
That happens because when a thread exits, and is joined, glibc does:
nptl/pthread_join.c:
pthread_join ()
{
...
if (__glibc_likely (result == 0))
{
/* We mark the thread as terminated and as joined. */
pd->tid = -1;
...
/* Free the TCB. */
__free_tcb (pd);
}
So if we attach or interrupt the program (which does an implicit "info
threads") at just the right (or rather, wrong) time, we can find and
return threads in the libthread_db/pthreads thread list with kernel
thread ID -1. I've filed glibc PR nptl/17707 for this. You'll find
more info there.
This patch handles this as a special case in GDB.
This is actually more than just a cosmetic issue. lin_lwp_attach_lwp
will think that this -1 is an LWP we're not attached to yet, and after
failing to attach will try to check we were already attached to the
process, using a waitpid call, which in this case ends up being
"waitpid (-1, ...", which obviously results in GDB potentially
discarding an event when it shouldn't...
Tested on x86_64 Fedora 20, native and gdbserver.

Linux: on attach, attach to lwps listed under /proc/$pid/task/
... instead of relying on libthread_db.
I wrote a test that attaches to a program that constantly spawns
short-lived threads, which exposed several issues. This is one of
them.
On Linux, we need to attach to all threads of a process (thread group)
individually. We currently rely on libthread_db to list the threads,
but that is problematic, because libthread_db relies on reading data
structures out of the inferior (which may well be corrupted). If
threads are being created or exiting just while we try to attach, we
may trip on inconsistencies in the inferior's thread list. To work
around that, when we see a seemingly corrupt list, we currently retry
a few times:
static void
thread_db_find_new_threads_2 (ptid_t ptid, int until_no_new)
{
...
if (until_no_new)
{
/* Require 4 successive iterations which do not find any new threads.
The 4 is a heuristic: there is an inherent race here, and I have
seen that 2 iterations in a row are not always sufficient to
"capture" all threads. */
...
That heuristic may well fail, and when it does, we end up with threads
in the program that aren't under GDB's control. That's obviously bad
and results in quite mistifying failures, like e.g., the process dying
for seeminly no reason when a thread that wasn't attached trips on a
breakpoint.
There's really no reason to rely on libthread_db for this nowadays
when we have /proc mounted. In that case, which is the usual case, we
can list the LWPs from /proc/PID/task/. In fact, GDBserver is already
doing this. The patch factors out that code that knows to walk the
task/ directory out of GDBserver, and makes GDB use it too.
Like GDBserver, the patch makes GDB attach to LWPs and _not_ wait for
them to stop immediately. Instead, we just tag the LWP as having an
expected stop. Because we can only set the ptrace options when the
thread stops, we need a new flag in the lwp structure to keep track of
whether we've already set the ptrace options, just like in GDBserver.
Note that nothing issues any ptrace command to the threads between the
PTRACE_ATTACH and the stop, so this is safe (unlike one scenario
described in gdbserver's linux-low.c).
When we attach to a program that has threads exiting while we attach,
it's easy to race with a thread just exiting as we try to attach to
it, like:
#1 - get current list of threads
#2 - attach to each listed thread
#3 - ooops, attach failed, thread is already gone
As this is pretty normal, we shouldn't be issuing a scary warning in
step #3.
When #3 happens, PTRACE_ATTACH usually fails with ESRCH, but sometimes
we'll see EPERM as well. That happens when the kernel still has the
thread in its task list, but the thread is marked as dead.
Unfortunately, EPERM is ambiguous and we'll get it also on other
scenarios where the thread isn't dead, and in those cases, it's useful
to get a warning. To distiguish the cases, when we get an EPERM
failure, we open /proc/PID/status, and check the thread's state -- if
the /proc file no longer exists, or the state is "Z (Zombie)" or "X
(Dead)", we ignore the EPERM error silently; otherwise, we'll warn.
Unfortunately, there seems to be a kernel race here. Sometimes I get
EPERM, and then the /proc state still indicates "R (Running)"... If
we wait a bit and retry, we do end up seeing X or Z state, or get an
ESRCH. I thought of making GDB retry the attach a few times, but even
with a 500ms wait and 4 retries, I still see the warning sometimes. I
haven't been able to identify the kernel path that causes this yet,
but in any case, it looks like a kernel bug to me. As this just
results failure to suppress a warning that we've been printing since
about forever anyway, I'm just making the test cope with it, and issue
an XFAIL.

Use PTRACE_SINGLESTEP_ONE when single-stepping one thread.
Currently, when we receive a request to single-step one single thread
(Eg, when single-stepping out of a breakpoint), we use the
PTRACE_SINGLESTEP pthread request, which does single-step
the corresponding thread, but also resumes execution of all
other threads in the inferior.
This causes problems when debugging programs where another thread
receives multiple debug events while trying to single-step a specific
thread out of a breakpoint (with infrun traces turned on):
(gdb) continue
Continuing.

What happens is that GDB keeps sending requests to resume one specific
thread, and keeps receiving debugging events for other threads.
Things break down when the one of the other threads receives a debug
event for the second time (thread 146 in the example above).
This patch fixes the problem by making sure that only one thread
gets resumed, thus preventing the other threads from generating
an unexpected event.

[gdbserver/lynx] spurious failure to write in inferior memory
We noticed the following error on ppc-lynx178, using just about
any program:
(gdb) tar remote mytarget:4444
Remote debugging using mytarget:4444
0x000100c8 in _start ()
(gdb) b try
Breakpoint 1 at 0x10844: file try.adb, line 11.
(gdb) cont
Continuing.
!!!-> Cannot remove breakpoints because program is no longer writable.
!!!-> Further execution is probably impossible.
Breakpoint 1, try () at try.adb:11
11 Local : Integer := 18;
And, of course, trying to continue yielded the expected outcome:
(gdb) c
Continuing.
warning: Error removing breakpoint 1
Cannot remove breakpoints because program is no longer writable.
Further execution is probably impossible.
It turns out that the problem is caused by an intentional test
against a variable with an undefined value. After GDB receives
notification of the inferior stopping, it tries to remove the
breakpoint by sending a memory-write packet ("X10844,4:9 ").
This leads us to lynx_write_memory, where it tries to split
the memory-write into chunks of 4 bytes. And, in order to handle
writes which are not aligned on word boundaries, we have the
following code:
if (skip > 0 || truncate > 0)
/* We need to read the memory at this address in order to preserve
the data that we are not overwriting. */
lynx_read_memory (addr, (unsigned char *) &buf, xfer_size);
if (errno)
return errno;
(the comment explains what the code is about).
Unfortunately, the not-so-glaring error that we've made here is
that we're checking ERRNO regardless of whether we've called
lynx_read_memory. In our case, because we are writing 4 bytes
aligned on a word boundary, we do not call lynx_read_memory and
therefore test an ERRNO with an undefined value.

* lynx-low.c (lynx_write_memory): Put lynx_read_memory and

GDBserver: don't resume all threads if the Hc thread disapears
There's code in linux_wait_1 that resumes all threads if the Hc thread
disappears. It's the wrong thing to do, as GDB has told GDBserver to
resume only one thread, because e.g., the user has scheduler-locking
enabled, or because GDB was stepping the program over a breakpoint.
Resuming all threads behind GDB's back can't be good in either case.
The right thing to do is to detect that that the (only) resumed thread
is gone, and let GDB know about it. The Linux backend is already
doing that nowadays, since:
commit fa96cb382c12b099675c5cc238aaa7352a3fd3d7
Author: Pedro Alves <palves@redhat.com>
AuthorDate: Thu Feb 27 14:30:08 2014 +0000
Teach GDBserver's Linux backend about no unwaited-for children (TARGET_WAITKIND_NO_RESUMED).
The backend detects that all resumed threads have disappeared, and
returns TARGET_WAITKIND_NO_RESUMED to the core of GDBserver, which
then reports an error to GDB.
There's no need to frob the passed in ptid to wait for the continue
thread either -- linux_wait_for_event only returns events for resumed
threads.
The badness (of resuming threads) can actually be observed in the
testsuite, if we force-disable vCont support in GDBserver -- before
the patch, gdb.threads/no-unwaited-for-left.exp hangs if we disable
vCont:
(gdb) continue
Continuing.
FAIL: gdb.threads/no-unwaited-for-left.exp: continue to breakpoint: break-here (timeout)
... more cascading timeouts ....
After the patch, gdb.threads/no-unwaited-for-left.exp behaves the same
with or without vCont support:
(gdb) continue
Continuing.

Overall, this is also good for getting rid of a RSP detail from the backend.

gdbserver/win32: Rewrite debug registers handling
Don't use debug_reg_state for both:
* "intent" - what we want the debug registers to look like
* "reality" - what/which were the contents of the DR registers when
the event triggered
Reserve it for the former only, like in the GNU/Linux port.
Otherwise the core x86 debug registers code can get confused if the
inferior itself changes the debug registers since GDB last set them.
This is also a requirement for being able to set watchpoints while the
target is running, if/when we get to it on Windows. See the big
comment in x86_dr_stopped_data_address.
Seems to me this may also fixes propagating watchpoints to all threads
-- continue_one_thread only calls win32_set_thread_context (what
copies the DR registers to the thread), if something already fetched
the thread's context before. Something else may be masking this
issue, I haven't checked.
Smoke tested by running gdbserver under Wine, connecting to it from
GNU/Linux, and checking that I could trigger a watchpoint as expected.
Joel tested it on x86-windows using AdaCore's testsuite.

Honour SIGILL and SIGSEGV in cancel breakpoint and event lwp selection
I see the following fail on arm-none-linux-gnueabi testing,
(gdb) continue^M
Continuing.^M
^M
Program received signal SIGILL, Illegal instruction.^M
[Switching to Thread 1003]^M
handler (signo=10) at

33 tgkill (getpid (), gettid (), SIGUSR1); /* step-2 */^M
(gdb) FAIL: gdb.threads/sigstep-threads.exp: continue
the cause is that GDBserver doesn't cancel the breakpoint if the stop
signal is SIGILL. The kernel used here is a little old, 2.6.x, and
doesn't translate SIGILL to SIGTRAP when program hits breakpoint
instruction (which is an illegal instruction actually). GDB and
GDBserver can translate SIGILL to SIGTRAP under certain circumstance,
so it is not a problem here. See gdbserver/linux-low.c:linux_wait_1
/* If this event was not handled before, and is not a SIGTRAP, we
report it. SIGILL and SIGSEGV are also treated as traps in case
a breakpoint is inserted at the current PC. If this target does
not support internal breakpoints at all, we also report the
SIGTRAP without further processing; it's of no concern to us. */
maybe_internal_trap
= (supports_breakpoints ()
&& (WSTOPSIG (w) == SIGTRAP
|| ((WSTOPSIG (w) == SIGILL
|| WSTOPSIG (w) == SIGSEGV)
&& (*the_low_target.breakpoint_at) (event_child->stop_pc))));
However, SIGILL and SIGSEGV is not considered when cancelling
breakpoint, which causes the fail above. That is, when GDB is doing
software single step on address ADDR, both thread A and thread B hits the
software single step breakpoint, and get SIGILL. GDB selects the event
from thread A, removes the software single step breakpoint, and resume
the program. The event (SIGILL) from thread B is reported to GDB, but
GDB doesn't regard this SIGILL as SIGTRAP, because the breakpoint on
address ADDR was removed, so GDB reports "Program received signal
SIGILL".
The patch is to allow calling cancel_breakpoint if the signal is
SIGILL and SIGSEGV. This patch fixes the fail above. Likewise, event
lwp selection should honour SIGILL and SIGSEGV too.

Rename 32- and 64-bit Intel files from "i386" to "x86"
This commit renames nine files that contain code used by both 32- and
64-bit Intel ports such that their names are prefixed with "x86"
rather than "i386". All types, functions and variables within these
files are likewise renamed such that their names are prefixed with
"x86" rather than "i386". This makes GDB follow the convention used
by gdbserver such that 32-bit Intel code lives in files called
"i386-*", 64-bit Intel code lives in files called "amd64-*", and code
for both 32- and 64-bit Intel lives in files called "x86-*".
This commit only renames OS-independent files. The Linux ports of
both GDB and gdbserver now follow the i386/amd64/x86 convention fully.
Some ports still use the old convention where "i386" in file/function/
type/variable names can mean "32-bit only" or "32- and 64-bit" but I
don't want to touch ports I can't fully test except where absolutely
necessary.

The problem is that linux_wait_for_event deletes lwps that have exited
(even those not passed in as lwps of interest), while the lwp/thread
list is being walked on with find_inferior. find_inferior can handle
the current iterated inferior being deleted, but not others.
When killing lwps, we don't really care about any of the pending
status handling of linux_wait_for_event. We can just waitpid the lwps
directly, which is also what GDB does (see
linux-nat.c:kill_wait_callback). This way the lwps are not deleted
while we're walking the list. They'll be deleted by linux_mourn
afterwards.
This crash triggers several times when running the testsuite against
GDBserver with the native-gdbserver board (target remote), but as GDB
can't distinguish between GDBserver crashing and "kill" being
sucessful, as in both cases the connection is closed (the 'k' packet
doesn't require a reply), and the inferior is gone, that results in no
FAIL.
The patch adds a generic test that catches the issue with
extended-remote mode (and works fine with native testing too). Here's
how it fails with the native-extended-gdbserver board without the fix:

x86 Linux watchpoints: Couldn't write debug register: Invalid argument.
This patch fixes this on x86 Linux:
(gdb) watch *buf@2
Hardware watchpoint 8: *buf@2
(gdb) si
0x00000000004005a7 34 for (i = 0; i < 100000; i++); /* stepi line */
(gdb) del
Delete all breakpoints? (y or n) y
(gdb) watch *(buf+1)@1
Hardware watchpoint 9: *(buf+1)@1
(gdb) si
0x00000000004005a7 in main () at ../../../src/gdb/testsuite/gdb.base/watchpoint-reuse-slot.c:34
34 for (i = 0; i < 100000; i++); /* stepi line */
Couldn't write debug register: Invalid argument.
(gdb)
In the example above the debug registers are being switched from this
state:
CONTROL (DR7): 0000000000050101 STATUS (DR6): 0000000000000000
DR0: addr=0x0000000000601040, ref.count=1 DR1: addr=0x0000000000000000, ref.count=0
DR2: addr=0x0000000000000000, ref.count=0 DR3: addr=0x0000000000000000, ref.count=0
to this:
CONTROL (DR7): 0000000000010101 STATUS (DR6): 0000000000000000
DR0: addr=0x0000000000601041, ref.count=1 DR1: addr=0x0000000000000000, ref.count=0
DR2: addr=0x0000000000000000, ref.count=0 DR3: addr=0x0000000000000000, ref.count=0
That is, before, DR7 was setup for watching a 2 byte region starting
at what's in DR0 (0x601040).
And after, DR7 is setup for watching a 1 byte region starting at
what's in DR0 (0x601041).
We always write DR0..DR3 before DR7, because if we enable a slot's
bits in DR7, you need to have already written the corresponding
DR0..DR3 registers -- the kernel rejects the DR7 write with EINVAL
otherwise.
The error shown above is the opposite scenario. When we try to write
0x601041 to DR0, DR7's bits still indicate intent of watching a 2-byte
region. That DR0/DR7 combination is invalid, because 0x601041 is
unaligned. To watch two bytes, we'd have to use two slots. So the
kernel errors out with EINVAL.
Fix this by always first clearing DR7, then writing DR0..DR3, and then
setting DR7's bits.
A little optimization -- if we're disabling the last watchpoint, then
we can clear DR7 just once. The changes to nat/i386-dregs.c make that
easier to detect, and as bonus, they make it a little easier to make
sense of DR7 in the debug logs, as we no longer need to remember we're
seeing stale bits.
Tested on x86_64 Fedora 20, native and GDBserver.
This adds an exhaustive test that switches between many different
combinations of watchpoint types and addresses and widths.

Make it easy to make --disable-werror the default for both binutils and gdb
The goal of this patch is to provide an easy way to make
--disable-werror the default when building binutils, or the parts
of binutils that need to get built when building GDB. In development
mode, we want to continue making -Werror the default with GCC.
But, when making releases, I think we want to make it as easy as
possible for regular users to successfully build from sources.
GDB already has this kind of feature to turn -Werror as well as
the use of the libmcheck library. As GDB Release Manager, I take
advantage of it to turn those off after having cut the branch.
I'd like to be able to do the same for the binutils bits. And
perhaps Tristan will want to do the same for his releases too
(not sure, binutils builders might be a little savvier than GDB
builders).
This patch introduces a new file, called development.sh, which
just sets a variable called $development. In our development branches
(Eg. "master"), it's set to true. But setting it to false would allow
us to change the default behavior of various development-related
features to be turned off; in this case, it turns off the use of
-Werror by default (use --enable-werror to turn it back on).
bfd/ChangeLog:
* development.sh: New file.
* warning.m4 (AM_BINUTILS_WARNINGS): Source bfd/development.sh.
Make -Werror the default with GCC only if DEVELOPMENT is true.
* Makefile.am (CONFIG_STATUS_DEPENDENCIES): Add
$(srcdir)/development.sh.
* Makefile.in, configure: Regenerate.

* Makefile.am (CONFIG_STATUS_DEPENDENCIES): Add dependency on
bfd's development.sh.

* Makefile.in (config.status): Adjust dependency on development.sh.
* configure.ac: Adjust development.sh source call.
* configure: Regenerate.
gdb/gdbserver/ChangeLog:
* configure.ac: Adjust development.sh source call.
* Makefile.in (config.status): Adjust dependency on development.sh.
* configure: Regenerate.
Tested on x86_64-linux by building two ways: One with DEVELOPMENT
set to true, and one with DEVELOPMENT set to false. In the first
case, I could see the use of -Werror, while it disappeared in
the second case.

gdbserver: on GDB breakpoint reinsertion, also delete the breakpoint's commands.
If GDB decides to change the breakpoint's conditions or commands,
it'll reinsert the same breakpoint again, with the new options
attached, without deleting the previous breakpoint. E.g.,
(gdb) set breakpoint always-inserted on
(gdb) b main if 0
Breakpoint 1 at 0x400594: file foo.c, line 21.
Sending packet: $Z0,400594,1;X3,220027#68...Packet received: OK
(gdb) b main
Breakpoint 15 at 0x400594: file foo.c, line 21.
Sending packet: $Z0,400594,1#49...Packet received: OK
GDBserver understands this and deletes the breakpoint's previous
conditions. But, it forgets to delete the previous commands.

[GDBserver] Make Zx/zx packet handling idempotent.
This patch fixes hardware breakpoint regressions exposed by my fix for
"PR breakpoints/7143 - Watchpoint does not trigger when first set", at
https://sourceware.org/ml/gdb-patches/2014-03/msg00167.html
The testsuite caught them on Linux/x86_64, at least. gdb.sum:
gdb.sum:
FAIL: gdb.base/hbreak2.exp: next over recursive call
FAIL: gdb.base/hbreak2.exp: backtrace from factorial(5.1)
FAIL: gdb.base/hbreak2.exp: continue until exit at recursive next test
gdb.log:
(gdb) next
Program received signal SIGTRAP, Trace/breakpoint trap.
factorial (value=4) at ../../../src/gdb/testsuite/gdb.base/break.c:113
113 if (value > 1) { /* set breakpoint 7 here */
(gdb) FAIL: gdb.base/hbreak2.exp: next over recursive call
Actually, that patch just exposed a latent issue to "breakpoints
always-inserted off" mode, not really caused it. After that patch,
GDB no longer removes breakpoints at each internal event, thus making
some scenarios behave like breakpoint always-inserted on. The bug is
easy to trigger with always-inserted on.
The issue is that since the target-side breakpoint conditions support,
if the stub/server supports evaluating breakpoint conditions on the
target side, then GDB is sending duplicate Zx packets to the target
without removing them before, and GDBserver is not really expecting
that for Z packets other than Z0/z0. E.g., with "set breakpoint
always-inserted on" and "set debug remote 1":
(gdb) b main
Sending packet: $m410943,1#ff...Packet received: 48
Breakpoint 4 at 0x410943: file ../../../src/gdb/gdbserver/server.c, line 3028.
Sending packet: $Z0,410943,1#48...Packet received: OK
^^^^^^^^^^^^
(gdb) b main
Note: breakpoint 4 also set at pc 0x410943.
Sending packet: $m410943,1#ff...Packet received: 48
Breakpoint 5 at 0x410943: file ../../../src/gdb/gdbserver/server.c, line 3028.

^^^^^^^^^^^^
(gdb) b main
Note: breakpoints 4 and 5 also set at pc 0x410943.
Sending packet: $m410943,1#ff...Packet received: 48
Breakpoint 6 at 0x410943: file ../../../src/gdb/gdbserver/server.c, line 3028.
Sending packet: $Z0,410943,1#48...Packet received: OK
^^^^^^^^^^^^
(gdb) del

Sending packet: $Z0,410943,1#48...Packet received: OK
Sending packet: $Z0,410943,1#48...Packet received: OK
Sending packet: $z0,410943,1#68...Packet received: OK
And for Z1, similarly:
(gdb) hbreak main
Sending packet: $m410943,1#ff...Packet received: 48
Hardware assisted breakpoint 4 at 0x410943: file ../../../src/gdb/gdbserver/server.c, line 3028.
Sending packet: $Z1,410943,1#49...Packet received: OK
^^^^^^^^^^^^
Packet Z1 (hardware-breakpoint) is supported
(gdb) hbreak main
Note: breakpoint 4 also set at pc 0x410943.
Sending packet: $m410943,1#ff...Packet received: 48
Hardware assisted breakpoint 5 at 0x410943: file ../../../src/gdb/gdbserver/server.c, line 3028.
Sending packet: $Z1,410943,1#49...Packet received: OK
^^^^^^^^^^^^
(gdb) hbreak main
Note: breakpoints 4 and 5 also set at pc 0x410943.
Sending packet: $m410943,1#ff...Packet received: 48
Hardware assisted breakpoint 6 at 0x410943: file ../../../src/gdb/gdbserver/server.c, line 3028.
Sending packet: $Z1,410943,1#49...Packet received: OK
^^^^^^^^^^^^
(gdb) del
Delete all breakpoints? (y or n) y
Sending packet: $Z1,410943,1#49...Packet received: OK
^^^^^^^^^^^^
Sending packet: $Z1,410943,1#49...Packet received: OK
^^^^^^^^^^^^
Sending packet: $z1,410943,1#69...Packet received: OK
^^^^^^^^^^^^
So GDB sent a bunch of Z1 packets, and then when finally removing the
breakpoint, only one z1 packet was sent. On the GDBserver side (with
monitor set debug-hw-points 1), in the Z1 case, we see:
$ ./gdbserver :9999 ./gdbserver

DR2: addr=0x0, ref.count=0 DR3: addr=0x0, ref.count=0
That's one insert_watchpoint call for each Z1 packet, and then one
remove_watchpoint call for the z1 packet. Notice how ref.count
increased for each insert_watchpoint call, and then in the end, after
GDB told GDBserver to forget about the hardware breakpoint, GDBserver
ends with the the first debug register still with ref.count=4! IOW,
the hardware breakpoint is left armed on the target, while on the GDB
end it's gone. If the program happens to execute 0x410943 afterwards,
then the CPU traps, GDBserver reports the trap to GDB, and GDB not
having a breakpoint set at that address anymore, reports to the user a
spurious SIGTRAP.
This is exactly what is happening in the hbreak2.exp test, though in
that case, it's a shared library event that triggers a
breakpoint_re_set, when breakpoints are still inserted (because
nowadays GDB doesn't remove breakpoints while handling internal
events), and that recreates breakpoint locations, which likewise
forces breakpoint reinsertion and Zx packet resends...
That is a lot of bogus Zx duplication that should possibly be
addressed on the GDB side. GDB resends Zx packets because the way to
change the target-side condition, is to resend the breakpoint to the
server with the new condition. (That's an option in the packet: e.g.,
"Z1,410943,1;X3,220027" for "hbreak main if 0". The packets in the
examples above are shorter because the breakpoints don't have
conditions attached). GDB doesn't remove the breakpoint first before
reinserting it because that'd be bad for non-stop, as it'd open a
window where the inferior could miss the breakpoint. The conditions
actually haven't changed between the resends, but GDB isn't smart
enough to realize that.
(TBC, if the target doesn't support target-side conditions, then GDB
doesn't trigger these resends (init_bp_location calls
mark_breakpoint_location_modified, and that does nothing if condition
evaluation is on the host side. The resends are caused by the
'loc->condition_changed = condition_modified.' line.)
But, even if GDB was made smarter, GDBserver should really still
handle the resends anyway. So target-side conditions also aren't
really to blame. The documentation of the Z/z packets says:
"To avoid potential problems with duplicate packets, the operations
should be implemented in an idempotent way."
As such, we may want to fix GDB, but we should definitely fix
GDBserver. The fix is a prerequisite for target-side conditions on
hardware breakpoints anyway (and while at it, on watchpoints too).
GDBserver indeed already treats duplicate Z0 packets in an idempotent
way. mem-break.c has the concept of high-level and low-level
breakpoints, somewhat similar to GDB's split of breakpoints vs
breakpoint locations, and keeps track of multiple breakpoints
referencing the same address/location, for the case of an internal
GDBserver breakpoint or a tracepoint being set at the same address as
a GDB breakpoint. But, it only allows GDB to ever contribute one
reference to a software breakpoint location. IOW, if gdbserver sees a
Z0 packet for the same address where it already had a GDB breakpoint
set, then GDBserver won't create another high-level GDB breakpoint.
However, mem-break.c only tracks GDB Z0 breakpoints. The same logic
should apply to all kinds of Zx packets. Currently, gdbserver passes
down each duplicate Zx (other than Z0) request directly to the
target->insert_point routine. The x86 watchpoint support itself
refcounts watchpoint / hw breakpoint requests, to handle overlapping
watchpoints, and save debug registers. But that code doesn't (and
really shouldn't) handle the duplicate requests, assuming that for
each insert there will be a corresponding remove.
So the fix is to generalize mem-break.c to track all kinds of Zx
breakpoints, and filter out duplicates. As mentioned, this ends up
adding support for target-side conditions on hardware breakpoints and
watchpoints too (though GDB itself doesn't support the latter yet).
Probably the least obvious change in the patch is that it kind of
turns the breakpoint insert/remove APIs inside out. Before, the
target methods were only called for GDB breakpoints. The internal
breakpoint set/delete methods inserted memory breakpoints directly
bypassing the insert/remove target methods. That's not good when the
target should use a debug API to set software breakpoints, instead of
relying on GDBserver patching memory with breakpoint instructions, as
is the case of NTO.
Now removal/insertion of all kinds of breakpoints/watchpoints, either
internal, or from GDB, always go through the target methods. The
insert_point/remove_point methods no longer get passed a Z packet
type, but an internal/raw breakpoint type. They're also passed a
pointer to the raw breakpoint itself (note that's still opaque outside
mem-break.c), so that insert_memory_breakpoint /
remove_memory_breakpoint have access to the breakpoint's shadow
buffer. I first tried passing down a new structure based on GDB's
"struct bp_target_info" (actually with that name exactly), but then
decided against it as unnecessary complication.
As software/memory breakpoints work by poking at memory, when setting
a GDB Z0 breakpoint (but not internal breakpoints, as those can assume
the conditions are already right), we need to tell the target to
prepare to access memory (which on Linux means stop threads). If that
operation fails, we need to return error to GDB. Seeing an error, if
this is the first breakpoint of that type that GDB tries to insert,
GDB would then assume the breakpoint type is supported, but it may
actually not be. So we need to check whether the type is supported at
all before preparing to access memory. And to solve that, the patch
adds a new target->supports_z_point_type method that is called before
actually trying to insert the breakpoint.
Other than that, hopefully the change is more or less obvious.
New test added that exercises the hbreak2.exp regression in a more
direct way, without relying on a breakpoint re-set happening before
main is reached.

[GDBserver] Move Z packet defines and type convertion routines to shared code.
The Aarch64, MIPS and x86 Linux backends all have Z packet number
defines and corresponding protocol number to internal type convertion
routines. Factor them all out to gdbserver's core code, so we only
have one shared copy.
Tested on x86_64 Fedora 20, and also cross built for aarch64-linux-gnu
and mips-linux-gnu.

Add AVX512 registers support to GDB and GDBserver.
This patch adds support for the Intel(R) Advanced Vector
Extensions 512 (Intel(R) AVX-512) registers. Native and remote
debugging are covered by this patch.
Intel(R) AVX-512 is an extension to AVX to support 512-bit wide
SIMD registers in 64-bit mode (XMM0-XMM31, YMM0-YMM31, ZMM0-ZMM31).
The number of available registers in 32-bit mode is still 8
(XMM0-7, YMM0-7, ZMM0-7). The lower 256-bits of the ZMM registers
are aliased to the respective 256-bit YMM registers. The lower
128-bits are aliased to the respective 128-bit XMM registers.
There are also 8 new, dedicated mask registers (K0-K7) in both 32-bit
mode and 64-bit mode.

Conditional Z1 breakpoint hangs GDBserver.
While trying to fix hbreak2.exp against GDBserver I noticed this...
(gdb) hbreak main if 1
Sending packet: $m400580,40#2e...Packet received: e8d2ffffff5dc3554889e54883ec10c745fc00000000eb0eb800000000e8c1ffffff8345fc01817dfce70300007ee9b800000000c9c3662e0f1f840000000000
Sending packet: $m40058f,1#31...Packet received: c7
Hardware assisted breakpoint 1 at 0x40058f: file ../../../src/gdb/testsuite/gdb.base/break-idempotent.c, line 46.
Sending packet: $Z1,40058f,1;X3,220127#9b...
*hangs forever*
The issue is that nothing advances the packet pointer if
add_breakpoint_condition either fails to parse the agent expression,
or fails to find the breakpoint, resulting in an infinite loop in
process_point_options. The latter case should really be fixed by
GDBserver tracking GDB Z1 breakpoints in its breakpoint structures
like Z0 breakpoints are, but the latter case still needs handling.
add_breakpoint_commands has the same issue, though at present I don't
know any way to trigger it other than sending a manually cooked
packet.
Unbelievably, it doesn't look like we have any test that tries setting
a conditional hardware breakpoint. Looking at cond-eval-mode.exp, it
looks like the file was meant to actually test something, but it's
mostly empty today. This patch adds tests that tries all sorts of
conditional breakpoints and watchpoints. The test hangs/fails without
the GDBserver fix.
Tested on x86_64 Fedora 17.

Teach GDBserver's Linux backend about no unwaited-for children (TARGET_WAITKIND_NO_RESUMED).
GDBserver currently hangs forever in waitpid if the leader thread
exits before other threads, or if all resumed threads exit - e.g.,
next over a thread exit with sched-locking on. This is exposed by
leader-exit.exp. leader-exit.exp is part of a series of tests for a
set of related problems. See
<http://www.sourceware.org/ml/gdb-patches/2011-10/msg00704.html>:
"
To recap, on the Linux kernel, ptrace/waitpid don't allow reaping the
leader thread until all other threads in the group are reaped. When
the leader exits, it goes zombie, but waitpid will not return an exit
status until the other threads are gone. This is presently exercised
by the gdb.threads/leader-exit.exp test. The fix for that test, in
linux-nat.c:wait_lwp, handles the case where we see the leader gone
when we're stopping all threads to report an event to some other
thread to the core.
(...)
The latter bit about not blocking if there no resumed threads in the
process also applies to some other thread exiting, not just the main
thread. E.g., this test starts a thread, and runs to a breakpoint in
that thread:
...
(gdb) c
Continuing.

This patch fixes the issues by implementing TARGET_WAITKIND_NO_RESUMED
on GDBserver, similarly to what the patch above did for native
Linux GDB.
gdb.threads/leader-exit.exp now passes.
gdb.threads/no-unwaited-for-left.exp now at least errors out instead
of hanging:
continue
Continuing.
warning: Remote failure reply: E.No unwaited-for children left.

(gdb) FAIL: gdb.threads/no-unwaited-for-left.exp: continue stops when the main thread exits
The gdb.threads/non-ldr-exc-*.exp tests are skipped because GDBserver
unfortunately doesn't support fork/exec yet, but I'm confident this
fixes the related issues.
I'm leaving modeling TARGET_WAITKIND_NO_RESUMED in the RSP for a
separate pass.
(BTW, in case of error in response to a vCont, it would be better for
GDB to query the target for the current thread, or re-select one,
instead of assuming current inferior_ptid is still the selected
thread.)
This implementation is a little different from GDB's, because I'm
avoiding bringing in more of this broken use of waitpid(PID) into
GDBserver. Specifically, this avoids waitpid(PID) when stopping all
threads. There's really no need for wait_for_sigstop to wait for each
LWP in turn. Instead, with some refactoring, we make it reuse
linux_wait_for_event.

move some rsp bits into rsp-low.h
This moves various low-level remote serial protocol bits into
common/rsp-low.[ch].
This is as close to a pure move as possible. There are some
redundancies remaining but those will be dealt with in a subsequent
patch.
Note that the two variants of remote_escape_output disagreed on the
treatment of "*". On the theory that quoting cannot hurt but the
absence possibly can, I chose the gdbserver variant to be the
canonical one.

[remote/gdbserver] Don't lose signals when reconnecting.
Currently, when GDB connects in all-stop mode, GDBserver always
responds to the status packet with a GDB_SIGNAL_TRAP, even if the
program is actually stopped for some other signal.
(gdb) tar rem ...
...
(gdb) c
Program received signal SIGUSR1, User defined signal 1.
(gdb) disconnect
(gdb) tar rem ...
(gdb) c
(Or a GDB crash instead of an explicit disconnect.)
This results in the program losing that signal on that last continue,
because gdb will tell the target to resume with no signal (to suppress
the GDB_SIGNAL_TRAP, due to 'handle SISGTRAP nopass'), and that will
actually suppress the real signal the program had stopped for
(SIGUSR1). To fix that, I think we should make GDBserver report the
real signal the thread had stopped for in response to the status
packet:
@item ?
@cindex @samp{?} packet
Indicate the reason the target halted. The reply is the same as for
step and continue.
But, that raises the question -- which thread are we reporting the
status for? Due to how the RSP in all-stop works, we can only report
one status. The status packet's response is a stop reply packet, so
it includes the thread identifier, so it's not a problem packet-wise.
However, GDBserver is currently always reporting the status for first
thread in the thread list, even though that may well not be the thread
that got the signal that caused the program to stop. So the next
logical step would be to report the status for the
last_ptid/last_status thread (the last event reported to gdb), if it's
still around; and if not, fallback to some other thread.
There's an issue on the GDB side with that, though...
GDB currently always adds the thread reported in response to the
status query as the first thread in its list. That means that if we
start with e.g.,
(gdb) info threads
3 Thread 1003 ...
* 2 Thread 1002 ...
1 Thread 1001 ...
And reconnect:
(gdb) disconnect
(gdb) tar rem ...
We end up with:
(gdb) info threads
3 Thread 1003 ...
2 Thread 1001 ...
* 1 Thread 1002 ...
Not a real big issue, but it's reasonably fixable, by having GDB
fetch/sync the thread list before fetching the status/'?', and then
using the status to select the right thread as current on the GDB
side. Holes in the thread numbers are squashed before/after
reconnection (e.g., 2,3,5 becomes 1,2,3), but the order is preserved,
which I think is both good, and good enough.
However (yes, there's more...), the previous GDB that was connected
might have had gdbserver running in non-stop mode, or could have left
gdbserver doing disconnected tracing (which also forces non-stop), and
if the new gdb/connection is in all-stop mode, we can end up with more
than one thread with a signal to report back to gdb. As we can only
report one thread/status (in the all-stop RSP variant; the non-stop
variant doesn't have this issue), we get to do what we do at every
other place we have this situation -- leave events we can't report
right now as pending, so that the next resume picks them up.
Note all this ammounts to a QoI change, within the existing framework.
There's really no RSP change here.
The only user visible change (other than that the signal is program is
stopped at isn't lost / is passed to the program), is in "info
program", that now can show the signal the program stopped for. Of
course, the next resume will respect the pass/nopass setting for the
signal in question. It'd be reasonable to have the initial connection
tell the user the program was stopped with a signal, similar to when
we load a core to debug, but I'm leaving that out for a future change.
I think we'll need to either change how handle_inferior_event & co
handle stop_soon, or maybe bypass them completely (like
fork-child.c:startup_inferior) for that.
Tested on x86_64 Fedora 17.

On mainline/development, also link GDBserver with -lmcheck.
This factors --enable-libmcheck related bits from GDB's configure.ac
and makes GDBserver use them too. Specifically, the 'development'
global is moved to a separate script to it can be sourced by both GDB
and GDBserver, and the --enable-libmcheck/--disable-libmcheck bits
proper are moved to a new m4 file.
I started out by defining 'development' in the m4 file, but in the end
decided against it, as a separate script has the advantage that
changing it in release branches does not require regenerating
configure, unlike today.
I had also started out by making the new GDB_AC_LIBMCHECK itself
handle the yes/no default fallback depending on release/developement,
but since I had split out 'development' to a separate script, and, GDB
needs the python checks anyway (hence we'd need to do the python
checks in gdb's configure.ac, and pass in a 'default lmcheck yes/no'
parameter to GDB_AC_LIBMCHECK anyway), I ended up keeping
GDB_AC_LIBMCHECK isolated from the 'development' global. IOW, it's
the caller's business to handle it.
Tested on x86_64 Fedora 17. Built GDB and GDBserver with and without
--enable-libmcheck, and observed --enable-libmcheck overrides the
disablement of -lmcheck caused by python supporting threads, and that
GDBserver links with -lmcheck when expected. Also observed that
changing the 'development' global, and issuing "make" triggers a
relink, and '-lmcheck' is included or not from the link accordingly.

don't keep a gdb-specific date
Right now there are two nightly commits to update a file in the tree
with the current date. One commit is for BFD, one is for gdb.
It seems unnecessary to me to do this twice. We can make do with a
single such commit.
This patch changes gdb in a minimal way to reuse the BFD date -- it
extracts it from bfd/version.h and changes version.in to use the
placeholder string "DATE" for those times when a date is wanted.
I propose removing the cron job that updates the version on trunk, and
then check in this patch.
For release branches, we can keep the cron job, but just tell it to
rewrite bfd/version.h. I believe this is a simple change in the
crontab -- the script will work just fine on this file.
This also moves version.in and version.h into common/, to reflect
their shared status; and updates gdbserver to use version.h besides.

[GDBserver] Multi-process + multi-arch
This patch makes GDBserver support multi-process + biarch.
Currently, if you're debugging more than one process at once with a
single gdbserver (in extended-remote mode), then all processes must
have the same architecture (e.g., 64-bit vs 32-bit). Otherwise, you
see this:

... etc, etc ...
Even though the process was running a 32-bit program, GDBserver sent
back to GDB a register set in 64-bit layout.
A patch (http://sourceware.org/ml/gdb-patches/2012-11/msg00228.html) a
while ago made GDB track a target_gdbarch per inferior, and as
consequence, fetch a target description per-inferior. This patch is
the GDBserver counterpart, that makes GDBserver keep track of each
process'es XML target description and register layout. So in the
example above, GDBserver will send the correct register set in 32-bit
layout to GDB.
A new "struct target_desc" object (tdesc for short) is added, that
holds the target description and register layout information about
each process. Each `struct process_info' holds a pointer to a target
description. The regcache also gains a pointer to a target
description, mainly for convenience, and parallel with GDB (and
possible future support for programs that flip processor modes).
The low target's arch_setup routines are responsible for setting the
process'es correct tdesc. This isn't that much different to how
things were done before, except that instead of detecting the inferior
process'es architecture and calling the corresponding
init_registers_FOO routine, which would change the regcache layout
globals and recreate the threads' regcaches, the regcache.c globals
are gone, and the init_registers_$BAR routines now each initialize a
separate global struct target_desc object (one for each arch variant
GDBserver supports), and so all the init_registers_$BAR routines that
are built into GDBserver are called early at GDBserver startup time
(similarly to how GDB handles its built-in target descriptions), and
then the arch_setup routine is responsible for making
process_info->tdesc point to one of these target description globals.
The regcache module is all parameterized to get the regcache's layout
from the tdesc object instead of the old register_bytes, etc. globals.
The threads' regcaches are now created lazily. The old scheme where
we created each of them when we added a new thread doesn't work
anymore, because we add the main thread/lwp before we see it stop for
the first time, and it is only when we see the thread stop for the
first time that we have a chance of determining the inferior's
architecture (through the_low_target.arch_setup). Therefore when we
add the main thread we don't know which architecture/tdesc its
regcache should have.
This patch makes the gdb.multi/multi-arch.exp test now pass against
(extended-remote) GDBserver. It currently fails, without this patch.
The IPA also uses the regcache, so it gains a new global struct
target_desc pointer, which points at the description of the process it
is loaded in.
Re. the linux-low.c & friends changes. Since the register map
etc. may differ between processes (64-bit vs 32-bit) etc., the
linux_target_ops num_regs, regmap and regset_bitmap data fields are no
longer sufficient. A new method is added in their place that returns
a pointer to a new struct that includes all info linux-low.c needs to
access registers of the current inferior.
The patch/discussion that originally introduced
linux-low.c:disabled_regsets mentions that the disabled_regsets set
may be different per mode (in a biarch setup), and indeed that is
cleared whenever we start a new (first) inferior, so that global is
moved as well behind the new `struct regs_info'.
On the x86 side:
I simply replaced the i387-fp.c:num_xmm_registers global with a check
for 64-bit or 32-bit process, which is equivalent to how the global
was set. This avoided coming up with some more general mechanism that
would work for all targets that use this module (GNU/Linux, Windows,
etc.).

[GDBserver] Multi-process + multi-arch
This patch makes GDBserver support multi-process + biarch.
Currently, if you're debugging more than one process at once with a
single gdbserver (in extended-remote mode), then all processes must
have the same architecture (e.g., 64-bit vs 32-bit). Otherwise, you
see this:
Added inferior 2

... etc, etc ...
Even though the process was running a 32-bit program, GDBserver sent
back to GDB a register set in 64-bit layout.
A patch (http://sourceware.org/ml/gdb-patches/2012-11/msg00228.html) a
while ago made GDB track a target_gdbarch per inferior, and as
consequence, fetch a target description per-inferior. This patch is
the GDBserver counterpart, that makes GDBserver keep track of each
process'es XML target description and register layout. So in the
example above, GDBserver will send the correct register set in 32-bit
layout to GDB.
A new "struct target_desc" object (tdesc for short) is added, that
holds the target description and register layout information about
each process. Each `struct process_info' holds a pointer to a target
description. The regcache also gains a pointer to a target
description, mainly for convenience, and parallel with GDB (and
possible future support for programs that flip processor modes).
The low target's arch_setup routines are responsible for setting the
process'es correct tdesc. This isn't that much different to how
things were done before, except that instead of detecting the inferior
process'es architecture and calling the corresponding
init_registers_FOO routine, which would change the regcache layout
globals and recreate the threads' regcaches, the regcache.c globals
are gone, and the init_registers_$BAR routines now each initialize a
separate global struct target_desc object (one for each arch variant
GDBserver supports), and so all the init_registers_$BAR routines that
are built into GDBserver are called early at GDBserver startup time
(similarly to how GDB handles its built-in target descriptions), and
then the arch_setup routine is responsible for making
process_info->tdesc point to one of these target description globals.
The regcache module is all parameterized to get the regcache's layout
from the tdesc object instead of the old register_bytes, etc. globals.
The threads' regcaches are now created lazily. The old scheme where
we created each of them when we added a new thread doesn't work
anymore, because we add the main thread/lwp before we see it stop for
the first time, and it is only when we see the thread stop for the
first time that we have a chance of determining the inferior's
architecture (through the_low_target.arch_setup). Therefore when we
add the main thread we don't know which architecture/tdesc its
regcache should have.
This patch makes the gdb.multi/multi-arch.exp test now pass against
(extended-remote) GDBserver. It currently fails, without this patch.
The IPA also uses the regcache, so it gains a new global struct
target_desc pointer, which points at the description of the process it
is loaded in.
Re. the linux-low.c & friends changes. Since the register map
etc. may differ between processes (64-bit vs 32-bit) etc., the
linux_target_ops num_regs, regmap and regset_bitmap data fields are no
longer sufficient. A new method is added in their place that returns
a pointer to a new struct that includes all info linux-low.c needs to
access registers of the current inferior.
The patch/discussion that originally introduced
linux-low.c:disabled_regsets mentions that the disabled_regsets set
may be different per mode (in a biarch setup), and indeed that is
cleared whenever we start a new (first) inferior, so that global is
moved as well behind the new `struct regs_info'.
On the x86 side:
I simply replaced the i387-fp.c:num_xmm_registers global with a check
for 64-bit or 32-bit process, which is equivalent to how the global
was set. This avoided coming up with some more general mechanism that
would work for all targets that use this module (GNU/Linux, Windows,
etc.).

[GDBserver] Multi-process + multi-arch
This patch makes GDBserver support multi-process + biarch.
Currently, if you're debugging more than one process at once with a
single gdbserver (in extended-remote mode), then all processes must
have the same architecture (e.g., 64-bit vs 32-bit). Otherwise, you
see this:

... etc, etc ...
Even though the process was running a 32-bit program, GDBserver sent
back to GDB a register set in 64-bit layout.
A patch (http://sourceware.org/ml/gdb-patches/2012-11/msg00228.html) a
while ago made GDB track a target_gdbarch per inferior, and as
consequence, fetch a target description per-inferior. This patch is
the GDBserver counterpart, that makes GDBserver keep track of each
process'es XML target description and register layout. So in the
example above, GDBserver will send the correct register set in 32-bit
layout to GDB.
A new "struct target_desc" object (tdesc for short) is added, that
holds the target description and register layout information about
each process. Each `struct process_info' holds a pointer to a target
description. The regcache also gains a pointer to a target
description, mainly for convenience, and parallel with GDB (and
possible future support for programs that flip processor modes).
The low target's arch_setup routines are responsible for setting the
process'es correct tdesc. This isn't that much different to how
things were done before, except that instead of detecting the inferior
process'es architecture and calling the corresponding
init_registers_FOO routine, which would change the regcache layout
globals and recreate the threads' regcaches, the regcache.c globals
are gone, and the init_registers_$BAR routines now each initialize a
separate global struct target_desc object (one for each arch variant
GDBserver supports), and so all the init_registers_$BAR routines that
are built into GDBserver are called early at GDBserver startup time
(similarly to how GDB handles its built-in target descriptions), and
then the arch_setup routine is responsible for making
process_info->tdesc point to one of these target description globals.
The regcache module is all parameterized to get the regcache's layout
from the tdesc object instead of the old register_bytes, etc. globals.
The threads' regcaches are now created lazily. The old scheme where
we created each of them when we added a new thread doesn't work
anymore, because we add the main thread/lwp before we see it stop for
the first time, and it is only when we see the thread stop for the
first time that we have a chance of determining the inferior's
architecture (through the_low_target.arch_setup). Therefore when we
add the main thread we don't know which architecture/tdesc its
regcache should have.
This patch makes the gdb.multi/multi-arch.exp test now pass against
(extended-remote) GDBserver. It currently fails, without this patch.
The IPA also uses the regcache, so it gains a new global struct
target_desc pointer, which points at the description of the process it
is loaded in.
Re. the linux-low.c & friends changes. Since the register map
etc. may differ between processes (64-bit vs 32-bit) etc., the
linux_target_ops num_regs, regmap and regset_bitmap data fields are no
longer sufficient. A new method is added in their place that returns
a pointer to a new struct that includes all info linux-low.c needs to
access registers of the current inferior.
The patch/discussion that originally introduced
linux-low.c:disabled_regsets mentions that the disabled_regsets set
may be different per mode (in a biarch setup), and indeed that is
cleared whenever we start a new (first) inferior, so that global is
moved as well behind the new `struct regs_info'.
On the x86 side:
I simply replaced the i387-fp.c:num_xmm_registers global with a check
for 64-bit or 32-bit process, which is equivalent to how the global
was set. This avoided coming up with some more general mechanism that
would work for all targets that use this module (GNU/Linux, Windows,
etc.).

gdbserver/lynx178: spurious SIG61 signal when resuming inferior.
On ppc-lynx178, resuming the execution of a program after hitting
a breakpoint sometimes triggers a spurious SIG61 event:
(gdb) cont
Continuing.
Program received signal SIG61, Real-time event 61.
[Switching to Thread 39]
0x10002324 in a_test.task1 (<_task>=0x3ffff774) at a_test.adb:30
30 select -- Task 1
From this point on, continuing again lets the signal kill the program.
Using "signal 0" or configuring GDB to discard the signal does not
help either, as the program immediately reports the same signal again.
What happens is the following:
- GDB sends a single-step order to gdbserver: $vCont;s:31
This tells GDBserver to do a step using thread 0x31=49.
GDBserver does the step, and thread 49 receives the SIGTRAP
indicating that the step has finished.
- GDB then sends a "continue", but this time does not specify
which thread to continue: $vCont;c
GDBserver uses an arbitrary thread's ptid to resume the program's
execution (the current_inferior's ptid was chosen for that).
See lynx-low.c:lynx_resume:
if (ptid_equal (ptid, minus_one_ptid))
ptid = thread_to_gdb_id (current_inferior);
So far on all LynxOS platforms, this has been good enough. But
not so on LynxOS 178. If the ptid used to resume the execution
is not the same as the thread that did the step, we get the weird
signal.
This patch fixes the problem by saving the ptid of the thread
that last caused an event, received during a call to waitpid.
The ptid is saved in per-process private data.

* lynx-low.c (struct process_info_private): New type.
(lynx_add_process): New function.
(lynx_create_inferior, lynx_attach): Replace calls to

has been inlined in lynx_mourn;
(lynx_wait_1): Save the ptid in the process's private data.

Linux: No need to set ptrace event options in fork/clone children.
Oleg Nesterov told me that the Linux kernel copies the parent's ptrace
options to fork/clone children, so there's no need for GDB to do that
manually.
I was actually a bit surprised, since I thought the ptracer had to
always set the ptrace options itself, and GDB is indeed calling
PTRACE_SETOPTIONS for each new fork child, if it'll stay attached.
Looking at the history of that code, I found that is was actually I
who added that set-ptrace-options-in-children bit, back in
http://sourceware.org/ml/gdb-patches/2009-05/msg00656.html. But,
honestly, I don't recall why I needed that. I think I may have just
blindly believed it was necessary.
I then looked back at the history of all the PTRACE_SETOPTIONS code we
have, and found that gdb never did copy the ptrace options before my
patch. But, when gdbserver learnt to use PTRACE_EVENT_CLONE, at
http://sourceware.org/ml/gdb-patches/2007-10/msg00547.html, it was
made to do 'ptrace (PTRACE_SETOPTIONS, new_pid, 0,
PTRACE_O_TRACECLONE)' for all new clones. Hmmm. But, GDB itself
never did that, so it can't really ever have been necessary, I
believe, otherwise GDB should have been doing it too.
(GDBserver doesn't support following forks, and so naturally doesn't
do any PTRACE_SETOPTIONS on fork children.)
So this patch removes the -I believe- unnecessary ptrace syscalls.
Tested on x86_64 Fedora 17, native/gdbserver, and on x86_64 RHEL5
native/gdbserver (Linux 2.6.18, I think a ptrace-on-utrace kernel).
No regressions.

[gdbserver] Fix watchpoint support on Windows
Watchpoint support doesn't work anymore when using gdbserver on Windows.
They just never trigger.
The problem comes from the fact that we always set the debug registers
to zero, no matter what. This in turn comes from the fact that we
use i386_low_insert_watchpoint to compute the DR values:
return i386_low_insert_watchpoint (&debug_reg_state,
type, addr, len);
This function saves the new values in debug_reg_state. However,
the values we actually use when setting the DR registers are
taken from two different globals:
static unsigned dr_status_mirror;
static unsigned dr_control_mirror;
These are really never actually changed (their value is set from
the DR values read from the inferior, but since we never change
them, in practice, they never change).
The fix is to use the values provided by debug_reg_state, and
to eliminate the two dr_[...] globals.
gdb/gdbserver/ChangeLog:
* win32-i386-low.c (dr_status_mirror, dr_control_mirror): Delete.
(i386_dr_low_get_control, i386_dr_low_get_status): Use
dr_status_mirror and dr_control_mirror from debug_reg_state.

(i386_get_thread_context, i386_set_thread_context,
i386_thread_added): Use dr_status_mirror and dr_control_mirror
from debug_reg_state.

[LynxOS] Include sys/ptrace.h instead of ptrace.h.
This is one of the changes needed in order to build gdbserver on
LynxOS 5.x.
Really interesting: On LynxOS 4.x, there is a #warning when sys/ptrace.h
is used (explaining that ptrace.h will be used instead), whereas this
file was removed from LynxOS 5.x. The contents of sys/ptrace.h on 4.x
(or at least the meat of it):
#if defined(__GNUC__) || defined(__GNUG__)
#if !defined(__NO_INCLUDE_WARN__)
#warning Using <ptrace.h> instead of <sys/ptrace.h>
#endif /* defined(__NO_INCLUDE_WARN__) */
#endif /* defined(__GNUC__) || defined(__GNUG__) */
#include <ptrace.h>
The fix I went for, for now, is to just include <sys/ptrace.h>
unconditionally. I could have done some configury, but we already
have to build with -D__NO_INCLUDE_WARN__ to avoid the warnings
anyway, and that's unvoidable, due to system includes themselves
including the "wrong" header file.
Since <sys/ptrace.h> seems to be the choice that was made for LynxOS,
and since it works to include it on LynxOS 4.x, I think that's the simplest
solution.

[gdbserver] Move malloc.h include to server.h.
This patch moves all includes of malloc.h, which were introduced
purely to get access to alloca's declaration, to server.h, next
to the include of alloca.h.
There is one exception: gdbreplay.c, which does not include server.h.
In this case, the include of alloca.h was simply moved up a bit, next
to the include of malloc.h.
gdb/gdbserver/ChangeLog:
* gdbreplay.c: Move include of alloca.h up, next to include of
malloc.h.
* server.h: Add include of malloc.h.
* mem-break.c: Remove include of malloc.h.
* server.c, tracepoint.c, utils.c, win32-low.c: Likewise.

[PATCH] Unexpected EOF read from connection with GDB after inferior exits.
This is on GNU/Linux.
GDBserver does not exit properly when the inferior exits, as demonstrated
with any program using the procedure below:
% gdbserver-head :4444 simple_main
Process simple_main created; pid = 25681
Listening on port 4444
Then, in another terminal, start GDB, connect to GDBserver, and run
the program to completion:
% gdb-head simple_main
(gdb) tar rem :4444
(gdb) cont
Continuing.
Program exited normally.
Going back to the terminal where GDBserver is running, we see the following
output:
Child exited with status 0
readchar: Got EOF
Remote side has terminated connection. GDBserver will reopen the connection.
Listening on port 4444
The problem is that we're missing a call to mourn_inferior. As a result,
after we've handled the vCont packet, we fail to notice that there are
no process left to debug (target_running() returns true), and thus try
to continue reading from the remote socket. However, since GDB just
disconnected after having received the "exit with status 0" reply to the
vCont request, the read triggers the EOF exception.
gdb/gdbserver/ChangeLog:
* server.c (handle_v_cont): Call mourn_inferior if process
just exited.
(myresume): Likewise.
