remove gdb_string.h
This removes gdb_string.h. This patch is purely mechanical. I
created it by running the two commands:
git rm common/gdb_string.h
perl -pi -e's/"gdb_string.h"/<string.h>/;' *.[chyl] */*.[chyl]

nameless LOAD_DLL_DEBUG_EVENT causes ntdll.dll to be missing
We observed on Windows 2012 that we were unable to unwind past
exception handlers. For instance, with any Ada program raising
an exception that does not get handled:
% gnatmake -g a -bargs -shared
% gdb a
(gdb) start
(gdb) catch exception unhandled
Catchpoint 2: unhandled Ada exceptions
(gdb) c
Catchpoint 2, unhandled CONSTRAINT_ERROR at <__gnat_unhandled_exception> (
e=0x645ff820 <constraint_error>) at s-excdeb.adb:53
53 s-excdeb.adb: No such file or directory.
At this point, we can already see that something went wrong, since
the frame selected by the debugger corresponds to a runtime function
rather than the function in the user code that caused the exception
to be raised (in our case procedure A).
This is further confirmed by the fact that we are unable to unwind
all the way to procedure A:
(gdb) bt
#0 <__gnat_unhandled_exception> (e=0x645ff820 <constraint_error>)
at s-excdeb.adb:53

#5 0x000007fad3879f4d in ?? ()
Backtrace stopped: previous frame inner to this frame (corrupt stack?)
It turns out that the unwinder has been doing its job flawlessly
up until frame #5. The address in frame #5 is correct, but GDB
is not able to associate it with any symbol or unwind record.
And this is because this address is inside ntdll.dll, and when
we received the LOAD_DLL_DEBUG_EVENT for that DLL, the system
was not able to tell us the name of the library, thus causing us
to silently ignoring the event. Because GDB does not know about
ntdll.dll, it is unable to access the unwind information from it.
And because the function at that address does not use a frame
pointer, the unwinding becomes impossible.
This patch helps recovering ntdll.dll at the end of the "run/attach"
phase, simply by trying to locate that specific DLL again.
In terms of our medium to long term planning, it seems to me that
we should be able to simplify the code by ignoring LOAD_DLL_DEBUG_EVENT
during the startup phase, and modify windows_ensure_ntdll_loaded
to then detect and report all shared libraries after we've finished
inferior creation. But for a change just before 7.7 branch creation,
I thought it was safest to just handle ntdll.dll specifically. This
is less intrusive, and ntdll is the only DLL affected by the problem
I know so far.
gdb/ChangeLog:
* windows-nat.c (handle_load_dll): Add comments.
(windows_ensure_ntdll_loaded): New function.
(do_initial_windows_stuff): Use windows_ensure_ntdll_loaded.

FIXME: brobecker/2013-12-10:
|
|
|
|
|
It seems odd to be going through this search if the DLL name could
|
|
|
|
|
simply be extracted via "event->lpImageName". Moreover, some
|
|
|
|
|
experimentation with various versions of Windows seem to indicate
|
|
|
|
|
that it might still be too early for this DLL to be listed when
|
|
|
|
|
querying the system about the current list of modules, thus making
|
|
|
|
|
this attempt pointless.
|
|
|
|
|
|
|
|
|
|
This code can therefore probably be removed. But at the time of
|
|
|
|
|
this writing, we are too close to creating the GDB 7.7 branch
|
|
|
|
|
for us to make such a change. We are therefore defering it. */

/* If the user presses Ctrl-c while the debugger is waiting

for an event, he expects the debugger to interrupt his program

|
|
|
|
|
|
|
|
|
- The debugger and the program do not share the console, in
|
|
|
|
|
which case the Ctrl-c event only reached the debugger.
|
|
|
|
|
In that case, the ctrl_c handler will take care of interrupting
|
2011-01-12 01:23:29 +00:00
|
|
|
the inferior. Note that this case is working starting with
|
|
|
|
|
Windows XP. For Windows 2000, Ctrl-C should be pressed in the
|
2009-03-22 21:43:56 +00:00
|
|
|
inferior console.
|
|
|
|
|
|
|
|
|
|
- The debugger and the program share the same console, in which
|
|
|
|
|
case both debugger and inferior will receive the Ctrl-c event.
|
|
|
|
|
In that case the ctrl_c handler will ignore the event, as the
|
|
|
|
|
Ctrl-c event generated inside the inferior will trigger the
|
|
|
|
|
expected debug event.

FIXME: brobecker/2008-05-20: If the inferior receives the
|
|
|
|
|
signal first and the delay until GDB receives that signal
|
|
|
|
|
is sufficiently long, GDB can sometimes receive the SIGINT
|
|
|
|
|
after we have unblocked the CTRL+C handler. This would
|
|
|
|
|
lead to the debugger stopping prematurely while handling
|
|
|
|
|
the new-thread event that comes with the handling of the SIGINT
|
|
|
|
|
inside the inferior, and then stop again immediately when
|
|
|
|
|
the user tries to resume the execution in the inferior.
|
|
|
|
|
This is a classic race that we should try to fix one day. */

nameless LOAD_DLL_DEBUG_EVENT causes ntdll.dll to be missing
We observed on Windows 2012 that we were unable to unwind past
exception handlers. For instance, with any Ada program raising
an exception that does not get handled:
% gnatmake -g a -bargs -shared
% gdb a
(gdb) start
(gdb) catch exception unhandled
Catchpoint 2: unhandled Ada exceptions
(gdb) c
Catchpoint 2, unhandled CONSTRAINT_ERROR at <__gnat_unhandled_exception> (
e=0x645ff820 <constraint_error>) at s-excdeb.adb:53
53 s-excdeb.adb: No such file or directory.
At this point, we can already see that something went wrong, since
the frame selected by the debugger corresponds to a runtime function
rather than the function in the user code that caused the exception
to be raised (in our case procedure A).
This is further confirmed by the fact that we are unable to unwind
all the way to procedure A:
(gdb) bt
#0 <__gnat_unhandled_exception> (e=0x645ff820 <constraint_error>)
at s-excdeb.adb:53

from C:\[...]\libgnat-7.3.dll
#5 0x000007fad3879f4d in ?? ()
Backtrace stopped: previous frame inner to this frame (corrupt stack?)
It turns out that the unwinder has been doing its job flawlessly
up until frame #5. The address in frame #5 is correct, but GDB
is not able to associate it with any symbol or unwind record.
And this is because this address is inside ntdll.dll, and when
we received the LOAD_DLL_DEBUG_EVENT for that DLL, the system
was not able to tell us the name of the library, thus causing us
to silently ignoring the event. Because GDB does not know about
ntdll.dll, it is unable to access the unwind information from it.
And because the function at that address does not use a frame
pointer, the unwinding becomes impossible.
This patch helps recovering ntdll.dll at the end of the "run/attach"
phase, simply by trying to locate that specific DLL again.
In terms of our medium to long term planning, it seems to me that
we should be able to simplify the code by ignoring LOAD_DLL_DEBUG_EVENT
during the startup phase, and modify windows_ensure_ntdll_loaded
to then detect and report all shared libraries after we've finished
inferior creation. But for a change just before 7.7 branch creation,
I thought it was safest to just handle ntdll.dll specifically. This
is less intrusive, and ntdll is the only DLL affected by the problem
I know so far.

* windows-nat.c (handle_load_dll): Add comments.
(windows_ensure_ntdll_loaded): New function.
(do_initial_windows_stuff): Use windows_ensure_ntdll_loaded.

/* On certain versions of Windows, the information about ntdll.dll
|
|
|
|
|
is not available yet at the time we get the LOAD_DLL_DEBUG_EVENT,
|
|
|

thus preventing us from reporting this DLL as an SO. This has been
|
|
|
|
|
witnessed on Windows 8.1, for instance. A possible explanation
|
|
|
|
|
is that ntdll.dll might be mapped before the SO info gets created

|
|
by the Windows system -- ntdll.dll is the first DLL to be reported

that problem.

rather than the function in the user code that caused the exception
to be raised (in our case procedure A).
This is further confirmed by the fact that we are unable to unwind
all the way to procedure A:

Backtrace stopped: previous frame inner to this frame (corrupt stack?)
It turns out that the unwinder has been doing its job flawlessly
up until frame #5. The address in frame #5 is correct, but GDB
is not able to associate it with any symbol or unwind record.
And this is because this address is inside ntdll.dll, and when
we received the LOAD_DLL_DEBUG_EVENT for that DLL, the system
was not able to tell us the name of the library, thus causing us
to silently ignoring the event. Because GDB does not know about
ntdll.dll, it is unable to access the unwind information from it.
And because the function at that address does not use a frame
pointer, the unwinding becomes impossible.
This patch helps recovering ntdll.dll at the end of the "run/attach"
phase, simply by trying to locate that specific DLL again.
In terms of our medium to long term planning, it seems to me that
we should be able to simplify the code by ignoring LOAD_DLL_DEBUG_EVENT
during the startup phase, and modify windows_ensure_ntdll_loaded
to then detect and report all shared libraries after we've finished
inferior creation. But for a change just before 7.7 branch creation,
I thought it was safest to just handle ntdll.dll specifically. This
is less intrusive, and ntdll is the only DLL affected by the problem
I know so far.
gdb/ChangeLog:
* windows-nat.c (handle_load_dll): Add comments.
(windows_ensure_ntdll_loaded): New function.

nameless LOAD_DLL_DEBUG_EVENT causes ntdll.dll to be missing
We observed on Windows 2012 that we were unable to unwind past
exception handlers. For instance, with any Ada program raising
an exception that does not get handled:
% gnatmake -g a -bargs -shared
% gdb a
(gdb) start
(gdb) catch exception unhandled
Catchpoint 2: unhandled Ada exceptions
(gdb) c
Catchpoint 2, unhandled CONSTRAINT_ERROR at <__gnat_unhandled_exception> (

nameless LOAD_DLL_DEBUG_EVENT causes ntdll.dll to be missing
We observed on Windows 2012 that we were unable to unwind past
exception handlers. For instance, with any Ada program raising
an exception that does not get handled:
% gnatmake -g a -bargs -shared
% gdb a
(gdb) start
(gdb) catch exception unhandled
Catchpoint 2: unhandled Ada exceptions
(gdb) c
Catchpoint 2, unhandled CONSTRAINT_ERROR at <__gnat_unhandled_exception> (
e=0x645ff820 <constraint_error>) at s-excdeb.adb:53
53 s-excdeb.adb: No such file or directory.
At this point, we can already see that something went wrong, since
the frame selected by the debugger corresponds to a runtime function
rather than the function in the user code that caused the exception
to be raised (in our case procedure A).
This is further confirmed by the fact that we are unable to unwind
all the way to procedure A:
(gdb) bt
#0 <__gnat_unhandled_exception> (e=0x645ff820 <constraint_error>)

#5 0x000007fad3879f4d in ?? ()
Backtrace stopped: previous frame inner to this frame (corrupt stack?)
It turns out that the unwinder has been doing its job flawlessly
up until frame #5. The address in frame #5 is correct, but GDB
is not able to associate it with any symbol or unwind record.
And this is because this address is inside ntdll.dll, and when
we received the LOAD_DLL_DEBUG_EVENT for that DLL, the system
was not able to tell us the name of the library, thus causing us
to silently ignoring the event. Because GDB does not know about
ntdll.dll, it is unable to access the unwind information from it.
And because the function at that address does not use a frame
pointer, the unwinding becomes impossible.
This patch helps recovering ntdll.dll at the end of the "run/attach"
phase, simply by trying to locate that specific DLL again.
In terms of our medium to long term planning, it seems to me that
we should be able to simplify the code by ignoring LOAD_DLL_DEBUG_EVENT
during the startup phase, and modify windows_ensure_ntdll_loaded
to then detect and report all shared libraries after we've finished
inferior creation. But for a change just before 7.7 branch creation,
I thought it was safest to just handle ntdll.dll specifically. This
is less intrusive, and ntdll is the only DLL affected by the problem
I know so far.
gdb/ChangeLog:
* windows-nat.c (handle_load_dll): Add comments.
(windows_ensure_ntdll_loaded): New function.
(do_initial_windows_stuff): Use windows_ensure_ntdll_loaded.
Add FIXME comment.

/* FIXME: brobecker/2013-12-10: We should try another approach where
|
|
|
|
|
we first ignore all DLL load/unload events up until this point,
|
|
|
|
|
and then iterate over all modules to create the associated shared
|
|
|
|
|
objects. This is a fairly significant change, however, and we are
|
|
|
|
|
close to creating a release branch, so we are delaying it a bit,

after the branch is created. */

constify to_detach
This patch constifies the target_ops method to_detach.
This is a small cleanup, but also, I think, a bug-prevention fix,
since gdb already acts as if the "args" argument here was const.
In particular, top.c:quit_force calls kill_or_detach via
iterate_over_inferiors. kill_or_detach calls target_detach, passing
the same argument each time. So, if one of these methods was not
const-correct, then kill_or_detach would change its behavior in a
strange way.
I could not build every target I modified in this patch. I've
inspected them all by hand, though. Many targets do not use the
"args" parameter; a couple pass it to atoi; and a few pass it on to
the to_detach method of the target beneath. The only code that
required a real change was in linux-nat.c, and that only needed the
introduction of a temporary variable for const-correctness.

[native x86 GNU/Linux] Access debug register mirror from the corresponding process.

A natural fix would be to make xxx_get_debug_reg_state take an
inferior argument, but that doesn't work because of the case where we
detach breakpoints/watchpoints from the child fork, at a time there's
no inferior for the child fork at all. We do a nasty hack in
i386_inferior_data_get, but that relies on all callers pointing the
current inferior to the correct inferior, which isn't actually being
done by all callers, and I don't think we want to enforce that -- deep
in the bowls of linux-nat.c, there are many cases we resume lwps
behind the scenes, and it's be better to not have that code rely on
global state (as it doesn't today).
The fix is to decouple the watchpoints code from inferiors, making it
track target processes instead. This way, we can freely keep track of
the watchpoint mirrors for these processes behind the core's back.
Checkpoints also play dirty tricks with swapping the process behind
the inferior, so they get special treatment too in the patch (which
just amounts to calling a new hook). Instead of the old hack in
i386_inferior_data_get, where we returned a copy of the current
inferior's debug registers mirror, as soon as we detect a fork in the
target, we copy the debug register mirror from the parent to the child
process.
I don't have an old kernel handy to test, but I stepped through gdb doing
the watchpoint removal in the fork child in the watchpoint-fork test
seeing that the debug registers end up cleared in the child.
I didn't find the need for linux_nat_iterate_watchpoint_lwps. If
we use plain iterate_over_lwps instead, what happens is that
when removing watchpoints, that iterate_over_lwps doesn't actually
iterate over anything, since the fork child is not added to the
lwp list until later, at detach time, in linux_child_follow_fork.
And if we don't iterate over that lwp, we don't mark its debug
registers as needing update. But linux_child_follow_fork takes
care of doing that explicitly:
child_lp = add_lwp (inferior_ptid);
child_lp->stopped = 1;
child_lp->last_resume_kind = resume_stop;
make_cleanup (delete_lwp_cleanup, child_lp);
/* CHILD_LP has new PID, therefore linux_nat_new_thread is not called for it.
See i386_inferior_data_get for the Linux kernel specifics.
Ensure linux_nat_prepare_to_resume will reset the hardware debug
registers. It is done by the linux_nat_new_thread call, which is
being skipped in add_lwp above for the first lwp of a pid. */
gdb_assert (num_lwps (GET_PID (child_lp->ptid)) == 1);
if (linux_nat_new_thread != NULL)
linux_nat_new_thread (child_lp);
if (linux_nat_prepare_to_resume != NULL)
linux_nat_prepare_to_resume (child_lp);
ptrace (PTRACE_DETACH, child_pid, 0, 0);
so unless I'm missing something (quite possible) it ends up all
the same. But, the !detach-on-fork, and the "follow-fork child" paths
should also call linux_nat_new_thread, and they don't presently. It
seems to me in those cases we're not clearing debug regs correctly
when that's needed. Instead of copying that bit that works around
add_lwp bypassing the linux_nat_new_thread call, I thought it'd
be better to add an add_initial_lwp call to be used in the case we
really need to bypass linux_nat_new_thread, and make
add_lwp always call linux_nat_new_thread.
i386_cleanup_dregs is rewritten to forget about the current process
debug mirrors, which takes cares of other i386 ports. Only a couple
of extra tweaks here and there were needed, as some targets wheren't
actually calling i386_cleanup_dregs.
Tested on Fedora 17 x86_64 -m64/-m32.
GDBserver already fetches the i386_debug_reg_state from the right
process, and, it doesn't handle forks at all, so no fix is needed over
there.
