Tom Tromey 0120846339 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.

	* common/create-version.sh: New file.
	* Makefile.in (version.c): Use bfd/version.h, common/version.in,
	create-version.sh.
	(HFILES_NO_SRCDIR): Use common/version.h.

The multi-arch patch made GDBserver do the the wrong siginfo layout
conversion, because most uses of `linux_is_elf64' were removed, and it
ended up never set.  A global really is the wrong thing to use as
elf64-ness is a per-process property; `linux_is_elf64' was just
accidentally left behind.

Tested on x86_64 Fedora 17.

Pedro Alves 030031eed5 Lazily allocate 'struct regsets_info'::disabled_regsets.
There's no need for every arch to pre-allocate disabled_regsets.
Chances are the array won't be used.

(I have a hunch that with some more work we could dispense with
initialize_regsets_info.)

Pedro Alves 5da6eb0a10 Fix regression from multi-arch patch.
This fixes the regression reported at
<http://sourceware.org/ml/gdb-patches/2013-06/msg00185.html>.

GDBserver was reaching:

static int
regsets_fetch_inferior_registers (struct regsets_info *regsets_info,
				  struct regcache *regcache)
{
  struct regset_info *regset;
  int saw_general_regs = 0;
  int pid;
  struct iovec iov;

  regset = regsets_info->regsets;

  pid = lwpid_of (get_thread_lwp (current_inferior));
  while (regset->size >= 0)
    {
      void *buf, *data;
      int nt_type, res;

      if (regset->size == 0
	  || regsets_info->disabled_regsets[regset - regsets_info->regsets])
	{
>>>>>>>	  regset ++;      <<<<<<<  HERE
	  continue;
	}

Because info->disabled_regsets[] was not being initialized, and that
causes all sorts of wrong.

Pedro Alves 3aee891821 [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.).

Pedro Alves 6740dc9c3e [gdbserver] Don't assume vCont;r ADDR1,ADDR2 comes with a ptid attached.
This bit:

+	  p1 = strchr (p, ':');
+	  decode_address (&resume_info[i].step_range_end, p, p1 - p);

should not expect the ':' to be there.  An action without a ptid is
valid:

 "If an action is specified with no thread-id, then it is applied to any
 threads that don't have a specific action specified"

This is handled further below:

      if (p[0] == 0)
	{
	  resume_info[i].thread = minus_one_ptid;
	  default_action = resume_info[i];

	  /* Note: we don't increment i here, we'll overwrite this entry
	     the next time through.  */
	}
      else if (p[0] == ':')

A stub that doesn't support and report to gdb thread ids at all (like
metal metal targets) only will always only see a single default action
with no ptid.

Use unpack_varlen_hex instead of decode_address.  The former doesn't
need to be told where the hex number ends, and it actually returns
that info instead, which we can use for validation.

Tested on x86_64 Fedora 17.

Pedro Alves c2d6af84da range stepping: gdbserver (x86 GNU/Linux)
This patch adds support for range stepping to GDBserver, teaching it
about vCont;r.

It'd be easy to enable this for all hardware single-step targets
without needing the linux_target_ops hook, however, at least PPC needs
special care, due to the fact that PPC atomic sequences can't be
hardware single-stepped through, a thing which GDBserver doesn't know
about.  So this leaves the support limited to x86/x86_64.

        * lynx-low.c (lynx_resume): Fix null_ptid/minus_one_ptid
        confusion in comment.
2013-05-17 06:53:53 +00:00
Joel Brobecker d631c5a779 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.

Pedro Alves 04f5fe89ae Fix remaining GDBserver issues with !HAVE_THREAD_DB_H.
The previous patches are still not sufficient to build gdbserver with
our copy of thread_db.h.

../../../src/gdb/gdbserver/thread-db.c:316:6: error: ‘struct lwp_info’ has no member named ‘th’

make: *** [thread-db.o] Error 1

First, linux-low.h is including <thread_db.h> directly instead of our
gdb_thread_db.h, although thread-db.c includes the latter.  Then the
'th' field of struct lwp_info is only defined if HAVE_THREAD_DB_H is
defined, which is not true if we're using our replacement copy of
thread_db.h.  We have a USE_THREAD_DB symbol defined if we're building
thread-db.c that's ideal for this, however, it's currently only
defined when compiling linux-low.c (through a Makefile rule).  The
patch makes it defined when compiling any file.

Pedro Alves 3e74e146f2 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.

Pedro Alves f0ae6fc35c PR gdb/15236: gdbserver write to linux memory with zero length corrupts stack
PROBLEM:

The function linux_write_memory () in linux-low.c allocates a buffer
on the stack to hold a copy of the data to be written.

  register PTRACE_XFER_TYPE *buffer = (PTRACE_XFER_TYPE *)
    alloca (count * sizeof (PTRACE_XFER_TYPE));

"count" is the number of bytes to be written, rounded up to the
nearest multiple of sizeof (PTRACE_XFER_TYPE) and allowing for not
being an aligned address. The function later uses

  buffer[0] = ptrace (PTRACE_PEEKTEXT, pid,
                      (PTRACE_ARG3_TYPE) (uintptr_t) addr, 0);

The problem is that this function can be called to write zero bytes on
an aligned address, for example when receiving an X packet of length 0
(used to test if 8-bit write is supported). Under these circumstances,
count can be zero.

Since in this case, buffer[0] may never have been allocated, the stack
is corrupted and gdbserver may crash.

SOLUTION:

Writing zero bytes should always succeed. The patch below returns
successfully early if the length is zero, so avoiding the stack
corruption.

Verified on the ARC GDB 7.5.1 port.

Pedro Alves aca2255198 gdbserver:server.c - use unpack_varlen_hex to extract hex numbers.
Addresses, as most numbers in the RSP are hex encoded, with variable
length (that just means the width isn't specified, and there's no top
cap.  So they should be extracted with unpack_varlen_hex.

A couple spots in server.c are using strto(u)l, which doesn't work on
LLP64 targets.

This patch fixes it.

Tested on x86_64 Fedora 17.

Pedro Alves 0b1afbb37b Consistent use of (C) after "Copyright".
While writing the previous patch, I noticed that we're not consistent
with the (C) in the copyright header.  The maintainers manual prefers
having it, though also says it's optional.  We have over 10x more
files with (C) than without in gdb's code, so I spent a few minutes
grepping and fixing.  Funny enough, the testsuite has it backwards.
I'll leave that for another time.

Joel Brobecker 3f6e77ef16 LynxOS: Resume the same thread when receiving a thread create/exit event.
Before this patch, the ptid passed to lynx_resume was completely
ignored, and we used the current_inferior. This resulted in trying
to resume the inferior execution using the wrong ptid after having
received a thread create/exit event, because the inferior_ptid
was still set to the ptid prior to receiving the signal.

gdb/gdbserver/ChangeLog:

        * lynx-low.c (lynx_resume): Use the resume_info parameter
        to determine the ptid for the lynx_ptrace call, unless
        it is equal to minus_one_ptid, in which case we use the
        ptid of the current_inferior.
        (lynx_wait_1): After having received a thread create/exit
        event, resume the inferior's execution using the signaling
        thread's ptid, rather than the old ptid.
