Pedro Alves 1a3d890bcc [GDBserver]: Silence exits if GDB is connected through stdio.
If we make gdbserver gdb_continue_to_end actually expect a process
exit with GDBserver, we get many testsuite failures with the remote
stdio board:

-PASS: gdb.arch/amd64-disp-step.exp: continue until exit at amd64-disp-step
+FAIL: gdb.arch/amd64-disp-step.exp: continue until exit at amd64-disp-step (the program exited)
-PASS: gdb.base/break.exp: continue until exit at recursive next test
+FAIL: gdb.base/break.exp: continue until exit at recursive next test (the program exited)
-PASS: gdb.base/chng-syms.exp: continue until exit at breakpoint first time through
+FAIL: gdb.base/chng-syms.exp: continue until exit at breakpoint first time through (the program exited)
... etc. ...

This is what the log shows for all of them:

 (gdb) continue
 Continuing.

 Child exited with status 0
 GDBserver exiting
 [Inferior 1 (process 22721) exited normally]
 (gdb) FAIL: gdb.arch/amd64-disp-step.exp: continue until exit (the program exited)

The problem is the whole "Child exited ... GDBserver exiting" output,
that comes out of GDBserver, and that the testsuite is not expecting.

I pondered somehow making the testsuite adjust to this.  But,
testsuite aside, I think GDBserver should not be outputting this at
all when GDB is connected through stdio.  GDBserver will be printing
this in GDB's console, but the user can already tell from the regular
output that the inferior is gone.

Again, manually:

 (gdb) tar remote | ./gdbserver/gdbserver - program
 Remote debugging using | ./gdbserver/gdbserver - program
 Process program created; pid = 22486
 stdin/stdout redirected
 Remote debugging using stdio
 done.
 Loaded symbols for /lib64/ld-linux-x86-64.so.2
 0x000000323d001530 in _start () from /lib64/ld-linux-x86-64.so.2
 (gdb) c
 Continuing.
 Child exited with status 1
 ^^^^^^^^^^^^^^^^^^^^^^^^^^
 GDBserver exiting
 ^^^^^^^^^^^^^^^^^
 [Inferior 1 (process 22486) exited with code 01]
 (gdb)

Suppressing those two lines makes the output be exactly like when
debugging against a remote tcp gdbserver:

 (gdb) c
 Continuing.
 [Inferior 1 (process 22914) exited with code 01]
 (gdb)

	* server.c (process_serial_event): Don't output "GDBserver
	exiting" if GDB is connected through stdio.
	* target.c (mywait): Likewise, be silent if GDB is connected
	through stdio.

Joel Brobecker 97ad458125 [gdbserver/LynxOS]: Incomplete thread list after --attach
The current implementation is forgetting to populate the thread list
when attaching to the process. This results in an incomplete list of
threads when debugging a threaded program.

Unfortunately, as the added comments hints, there appears to be
no way of getting the list of threads via ptrace, other than by
spawning the "ps" command, and parsing its output. Not great,
but it appears to be the best we can do.

gdb/gdbserver/ChangeLog:

        * lynx-low.c (lynx_add_threads_after_attach): New function.
        (lynx_attach): Remove call to add_thread.  Add call to
        lynx_add_threads_after_attach instead.

Mike Frysinger 5b4e221c82 gdb: btrace: fix build errors on older glibc builds
It is possible to have a build of glibc where SYS_perf_event_open is not
defined (because when the glibc was compiled, the syscall did not exist),
but have newer kernel headers installed so that linux/perf_event.h is
available.  In this setup, you get a build failure:

./common/linux-btrace.c: In function 'kernel_supports_btrace':
./common/linux-btrace.c:316:23: error: 'SYS_perf_event_open' undeclared (first use in this function)

Update the ifdef check to also see if the syscall is available.

Pedro Alves 3aafd2ffb6 [gdbserver] Fix trace-buffer-size.exp FAILs.
I'm seeing trace-buffer-size.exp failing (with gdbserver):

  (gdb) PASS: gdb.trace/trace-buffer-size.exp: tstatus check 2
  show trace-buffer-size 4
  Requested size of trace buffer is 4.
  (gdb) PASS: gdb.trace/trace-buffer-size.exp: show trace buffer size
  set trace-buffer-size -1
  memory clobbered past end of allocated block
  Remote connection closed
  (gdb) FAIL: gdb.trace/trace-buffer-size.exp: set trace buffer size 2
  set trace-buffer-size unlimited
  (gdb) PASS: gdb.trace/trace-buffer-size.exp: set trace-buffer-size unlimited

That "memory clobbered past end of allocated block" is mcheck triggering.

Valgrind shows:

  ==23624== Invalid write of size 1
  ==23624==    at 0x418DD8: clear_trace_buffer (tracepoint.c:1443)
  ==23624==    by 0x418F3A: init_trace_buffer (tracepoint.c:1497)
  ==23624==    by 0x41D95B: cmd_bigqtbuffer_size (tracepoint.c:4061)
  ==23624==    by 0x41DEEC: handle_tracepoint_general_set (tracepoint.c:4193)

clear_trace_buffer does:

  static void
  clear_trace_buffer (void)
  {
    trace_buffer_start = trace_buffer_lo;
    trace_buffer_free = trace_buffer_lo;
    trace_buffer_end_free = trace_buffer_hi;
    trace_buffer_wrap = trace_buffer_hi;
    /* A traceframe with zeroed fields marks the end of trace data.  */
    ((struct traceframe *) trace_buffer_free)->tpnum = 0;
    ((struct traceframe *) trace_buffer_free)->data_size = 0;
    traceframe_read_count = traceframe_write_count = 0;
    traceframes_created = 0;
  }

And the tpnum+data_size fields are over 4 bytes...  This fixes it by
ensuring we allocate space at least for an EOB.  We have code
elsewhere that relies on the EOB being present (like e.g.,
find_traceframe), so this seems simplest.

Pedro Alves 9a13b2fa01 server.c:gdb_read_memory: Fix error return.
When I added gdb_read_memory, with bits factored out from elsewhere, I
missed adjusting this error return.  gdb_read_memory has an interface
similar to Like GDB's xfer_partial:

> /* Read trace frame or inferior memory.  Returns the number of bytes
>   actually read, zero when no further transfer is possible, and -1 on
>   error.  Return of a positive value smaller than LEN does not
>   indicate there's no more to be read, only the end of the transfer.

Returning EIO, a positive value, is obviously bogus, for the caller
will confuse it with a successful partial transfer.

Found by inspection.

Pedro Alves 17ef446eed 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.

Pedro Alves d5749ee715 [GDBserver] hostio.c: Fallback to packet buffer size if PATH_MAX is not available.
PATH_MAX is not defined on systems which have no limit on filename
length, such as GNU/Hurd.  As designed, the hostio RSP packets carry
the paths as parameters in the request/reply packets, which themselves
have an upper size limit, so lifting the filename limit completely
would require a redesign with new hostio packets.  While that doesn't
happen, we can at least support filename lengths as long as the packet
buffer can fit.

Pedro Alves d8d2a3ee47 Normalize on PATH_MAX instead of MAXPATHLEN throughout.
With the pathmax gnulib module in place, we can use PATH_MAX
consistently throughout, instead of the current mixbag of PATH_MAX and
MAXPATHLEN uses.  It's no longer necessary to include sys/param.h
(supposedly, I can't check all ports touched here) for MAXPATHLEN.

Don't remove sys/param.h from GDB's configure.ac, as later tests in
the file use HAVE_SYS_PARAM_H checks.

Tested on x86_64 Fedora 17.

Pedro Alves bc7dea8de9 Rely on gnulib's unistd.h replacement.
With gnulib's unistd module, we can assume unistd.h is always present, and that
STDIN_FILENO, STDOUT_FILENO, STDERR_FILENO are always defined.

Don't remove unistd.h from GDB's configure.ac, as later tests in the
file use HAVE_UNISTD_H checks.

Mircea Gherzan 257b6bec77 gdbserver: fix the standalone build
When directly invoking gdb/gdbserver/configure && make, the build will
fail because the $(host_alias) is empty and thus create-version.sh does
not get enough parameters.

The output of gdbserver --version without this patch (built like above):

  [...]
  This gdbserver was configured as ""

After applying this patch:

  [...]
  This gdbserver was configured as "x86_64-unknown-linux-gnu"

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.
	* version.in: Move to ...
	* common/version.in: ... here.  Replace date with "DATE".
	* version.h: Move to ...
	* common/version.h: ... here.

	* Makefile.in (version.c): Use bfd/version.h, common/version.in,
	create-version.sh.
	(version.o): Remove.

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.
