Subject: [patch or FYI] testsuite: Fix prelink.exp on system w/unprelinked system libs
Hi,
this is a more conservative variant superseded by:
[patch 4/6] testsuite: Unify to lib/prelink-support.exp
http://sourceware.org/ml/gdb-patches/2010-03/msg01002.html
where gdb.base/prelink.exp is reworked on generic lib/prelink-support.exp.
I prefer the [patch 4/6] over this patch but this mail can serve also as an
illustration of the current problem.
------------------------------------------------------------------------------
If your system for some reason currently does not have all the libraries
prelinked gdb.base/prelink.exp will get UNRESOLVED randomly also affecting
testsuite results diff.
Apparently the testcase already tried to avoid any system libraries
dependencies by "-nodefaultlibs". But currently it does has not worked that
way.
"-lm" is contained already even in dejagnu's default_target_compile (not just
in gdb/testsuite/lib/ada.exp). But I do not know why it is there and which
systems would get broken by some global gdb/testsuite/ "-lm" removal.
Thanks,
Jan
2010-03-29 Jan Kratochvil <jan.kratochvil@redhat.com>

Subject: [patch 03/15] PIE: breakpoint_address_match gdbarch_addr_bit workaround
Hi,
there are already multiple cases of CORE_ADDR being masked by the width of
gdbarch_addr_bit. This specific new case was required the PIE support.
Please read the C comment in attached patch.
Checked that CORE_ADDR math operations are present on 6000+ lines of code of
GDB sources which makes it impossible to do some general fix by replacing all
a->addr < b->addr
by
addr_less_than (a->addr, b->addr)
etc.
Even with this patch I think there are still many bugs left in the operation
of x86_64 gdb debugging i386 targets. Do you find the C++ way as a viable
one?
Thanks,
Jan

http://sourceware.org/ml/gdb-patches/2010-02/msg00625.html
Subject: RFC: fix bug with std::terminate handler
I would appreciate comments on this patch.
This comes from an automatically-reported bug in the Red Hat bugzilla:
https://bugzilla.redhat.com/show_bug.cgi?id=562975
call_function_by_hand installs a momentary breakpoint on std::terminate,
and then deletes it later. However, this can cause a double deletion of
the breakpoint. In the bug, the called function is dlopen, which causes
gdb to enter solib_add, which calls breakpoint_re_set, deleting the
momentary breakpoint.
This fix works by creating the momentary breakpoint with an internal
breakpoint number, and then trying to delete the breakpoint by number.
This bug does not always manifest in a crash. In fact, I couldn't make
it crash here, but I could observe the problem under valgrind.
Built and regtested on x86-64 (compile farm). I also manually verified
it using valgrind.
I think this patch is mildly ugly, due to the introduction of
set_momentary_breakpoint_at_pc_with_number. However, in the absence of
comments, I plan to check it in after a reasonable waiting period.

Subject: [patch] Fix dangling displays in separate debug
[ Backported. ]
Hi,
gdb.base/solib-display.exp using _separate_ debug info:
3: c_global = gdbtypes.c:1369: internal-error: check_typedef: Assertion `type' failed.
A problem internal to GDB has been detected,
This problem was fixed before by:
[patch 1/8] Types GC [unloading observer]
http://sourceware.org/ml/gdb-patches/2009-05/msg00544.html
Re: [patch 3/8] Types GC [display_uses_solib_p to exp_iterate]
http://sourceware.org/ml/gdb-patches/2009-07/msg00054.html
but as that patchset is still not in providing this temporary fixup instead.
One may only address that gdb.base/solib-display.exp was testing symbol
in-objfile while now it tests only symbol in-sepdebug-objfile and no longer
the in-objfile case. I find the in-sepdebug-objfile as a superset of
in-objfile test but I can rework it if anyones addresses this test change.
No regressions on {x86_64,x86_64-m32,i686}-fedora12-linux-gnu.
Thanks,
Jan

Subject: [patch] Fix crash on NULL function's TYPE_FIELD_TYPE
Hi,
seen one possibility of a crash.
#0 c_print_type (type=0x0, ...)
#1 in c_type_print_args (type=0xfceb890,
(The real reason of a reported GDB crash was different, though.)
Thanks,
Jan
gdb/
2010-03-30 Jan Kratochvil <jan.kratochvil@redhat.com>
Fix crash on reading wrong function declaration DWARF.
* dwarf2read.c (read_subroutine_type): New variable void_type.
Pre-fill all TYPE_FIELD_TYPEs. Move nparams and iparams initialization
more close to their use.

@cindex active targets
@cindex multiple targets
-There are three classes of targets: processes, core files, and
-executable files. @value{GDBN} can work concurrently on up to three
-active targets, one in each class. This allows you to (for example)
-start a process and inspect its activity without abandoning your work on
-a core file.
-
-For example, if you execute @samp{gdb a.out}, then the executable file
-@code{a.out} is the only active target. If you designate a core file as
-well---presumably from a prior run that crashed and coredumped---then
-@value{GDBN} has two active targets and uses them in tandem, looking
-first in the corefile target, then in the executable file, to satisfy
-requests for memory addresses. (Typically, these two classes of target
-are complementary, since core files contain only a program's
-read-write memory---variables and so on---plus machine status, while
-executable files contain only the program text and initialized data.)
-
-When you type @code{run}, your executable file becomes an active process
-target as well. When a process target is active, all @value{GDBN}
-commands requesting memory addresses refer to that target; addresses in
-an active core file or executable file target are obscured while the
-process target is active.
-
-Use the @code{core-file} and @code{exec-file} commands to select a new
-core file or executable target (@pxref{Files, ,Commands to Specify
-Files}). To specify as a target a process that is already running, use
-the @code{attach} command (@pxref{Attach, ,Debugging an Already-running
-Process}).
+There are multiple classes of targets such as: processes, executable files or
+recording sessions. Core files belong to the process class, there can be
+active only one of a core or a running process. Otherwise @value{GDBN} can
+work concurrently on multiple active targets, one in each class. This allows
+you to (for example) start a process and inspect its activity while still
+having access to the executable file after the process finishes. Or if you
+start process recording (@pxref{Reverse Execution}) and @code{reverse-step}
+there you are presented a virtual layer of the recording target while the
+process target remains stopped at the chronologically last point of the process
+execution.
+
+Use the @code{core-file} and @code{exec-file} commands to select a new core
+file or executable target (@pxref{Files, ,Commands to Specify Files}). To
+specify as a target a process that is already running, use the @code{attach}

Subject: [patch] infcall: Remove gdb_assert ($sp overflow)
Hi,
set $sp=0
call something()
->
../../gdb/infcall.c:521: internal-error: call_function_by_hand: Assertion
`(gdbarch_inner_than (gdbarch, 1, 2) && sp <= old_sp) || (gdbarch_inner_than
(gdbarch, 2, 1) && sp >= old_sp)' failed.
as $sp - frame == 0xffffsmth which is not lower than $sp.
It must not be gdb_assert(). It can be an error() but I left it just to do:
(gdb) set $sp=0
(gdb) call doubleit (1)
Cannot access memory at address 0xffffffffffffff78
(gdb) set $sp=-1
(gdb) call doubleit (1)
Cannot access memory at address 0xffffffffffffff68
Unaware how inconvenient is an intentional crash of the testcase on some
embedded/non-MMU systems.
No regressions on {x86_64,x86_64-m32,i686}-fedora12-linux-gnu.
Thanks,
Jan

Subject: [patch 1/6]: PIE: Attach binary even after re-prelinked underneath
Hi,
there is a regression (against previous unreleased commits) by:
Re: RFC: Verify AT_ENTRY before using it
http://sourceware.org/ml/gdb-patches/2010-03/msg00395.html
for loading PIE executables which have changed on the disk since started.
There are in fact 3 different addresses one has to properly deal with.
This patch uses explicit "file" so it is not dependent on pending:
[patch] Attach to running but deleted executable
http://sourceware.org/ml/gdb-patches/2010-03/msg00950.html
The two copy-pasted blocks for elf32 and elf64 are "not nice" but this is the
current style in GDB.
No regressions on {x86_64,x86_64-m32,i686}-fedora12-linux-gnu for the whole
patch series together.
Thanks,
Jan

* gdb.base/break-interp.exp: Run $binpie with new value "ATTACH", new
code for it. New variable relink_args.
(prelinkYES): Call prelinkNO.
(test_attach): Accept new parameter relink_args. Re-prelink the binary
in such case. Move the core code to ...
(test_attach_gdb): ... a new function. Send GDB command "file".

Subject: [patch 2/6] PIE: Attach binary even after ld.so re-prelinked underneath
Hi,
when I have seen the PIE-binary-changed-sice-start tested also
ld.so-changed-since-start and it did not work.
There is questionable when to print and when to not to print non-fatal memory
read errors. Similar change I requested in
Re: [RFC/ia64] memory error when reading wrong core file
http://sourceware.org/ml/gdb-patches/2010-02/msg00001.html
so that GDB prints at least as a warning
Cannot access memory at address ...
when some unexpected error happens.
Contrary to it there is not such warning present in the code below as in the
case of non-valgrind PIE with re-prelinked ld.so the memory read error happens
there. Some GDB code rework could probably avoid it.
Just for example all the memory read errors in read_program_header or even
- primarily - scan_dyntag are currently IMO-incorrectly silent and others.
Therefore posted the patch this way, making all these warnings printed and
possibly fixing code attempting incorrect reads along the way could be done by
a different patch.
No regressions on {x86_64,x86_64-m32,i686}-fedora12-linux-gnu for the whole
patch series together.

Subject: [patch 3/6] PIE: Fix occasional error attaching i686 binary
[ Testcase diff backported. ]
Hi,
this is the real bugreport which started this patch series.
gdb "Cannot access memory" on a running process
https://bugzilla.redhat.com/show_bug.cgi?id=576742
Offsets on i686 cause that while attaching to an unprelinked running PIE
scan_dyntag will incorrectly get a successful read in scan_dyntag from DT_DEBUG
it expects is from the mani executable but in fact it is from some ld.so or
libc.so (located low for --exec-shield). Another issue is that scan_dyntag
could verify more that the target memory matches the .dynamic section it is
reading from exec_bfd. It could also complain when the read failed (as always
failed so for for PIE attaches first, succeeded later so nobody has noticed
anything).
The successful read reads a bogus DT_DEBUG value and GDB errors on it later.
This is again a non-fatal error after the patch by Joel Brobecker above but it
was not so before and it is incorrect anyway.
The svr4_relocate_main_executable call in svr4_special_symbol_handling was
there before delayed that way for svr4_static_exec_displacement.
But svr4_static_exec_displacement has been removed in the meantime by:
Re: RFC: Verify AT_ENTRY before using it
http://sourceware.org/ml/gdb-patches/2010-03/msg00030.html
So it can be simplified + corrected now. Moreover GDB will now finally print
exactly "Using PIE (Position Independent Executable) displacement" exactly
once.
The reproducer depends on various offsets which may be distro dependent but it
was made so that it is hopefully reproducible everywhere. Reproduced + fixed
on Fedora 12 x86_64 and i686.
No regressions on {x86_64,x86_64-m32,i686}-fedora12-linux-gnu for the whole
patch series together.

The first part has caused the regression for PIE on native x86* GNU/Linux host.
As I believe for Daniel J.'s seen regression of `qOffsets' the second already
checked-in part is sufficient - I would like to remove the first part.
OK to check it in?
No regressions on {x86_64,x86_64-m32,i686}-fedora12-linux-gnu.
(I do not think one needs to think about 7.1-branch as it is not a regression
against any FSF GDB release.)

Subject: [gdb FYI-patch] callback-mode readline-6.0 regression
Hi Chet,
FSF GDB currently ships bundled with readline-5.2 which works fine.
But using --with-system-readline and readline-6.0-patchlevel4 has
a regression:
readline-5.2: Run `gdb -nx -q' and type CTRL-C:
(gdb) Quit
(gdb) _
readline-6.0: Run `gdb -nx -q' and type CTRL-C:
(gdb) _
= nothing happens (it gets buffered and executed later)
(It does also FAIL on gdb.gdb/selftest.exp.)
It is because GDB waits in its own poll() mainloop and readline uses via
rl_callback_handler_install and rl_callback_handler_remove. This way the
readline internal variable _rl_interrupt_immediately remains 0 and CTRL-C gets
only stored to _rl_caught_signal but not executed.
Seen in rl_signal_handler even if _rl_interrupt_immediately is set and
_rl_handle_signal is called then the signal is still stored to
_rl_caught_signal. In the _rl_interrupt_immediately case it should not be
stored when it was already processed.
rl_signal_handler does `_rl_interrupt_immediately = 0;' - while I am not aware
of its meaning it breaks the nest-counting of other routines which do
`_rl_interrupt_immediately++;' and `_rl_interrupt_immediately--;' possibly
creating problematic `_rl_interrupt_immediately == -1'.
`_rl_interrupt_immediately' is an internal variable, how it could be accessed
by a readline application? (OK, maybe it should not be used.)
Attaching a current GDB-side patch but it must access readline internal
variable _rl_caught_signal and it is generally just a workaround. Could you
please include support for signals in this asynchronous mode in readline-6.1?
I find it would be enough to make RL_CHECK_SIGNALS public?
GDB: No regressions on {x86_64,x86_64-m32,i686}-fedora12-linux-gnu.
But this is not a patch intended to be accepted.
Thanks,
Jan

Watchpoint 4 deleted because the program has left the block in
which its expression is valid.
There is already automatic deletion of RELATED_BREAKPOINT in
map_breakpoint_numbers but "delete breakpoints" (for all the breakpoints)
calls delete_breakpoint from delete_command directly without calling
map_breakpoint_numbers and it does not delete the associated
bp_watchpoint_scope.
I find the attached patch is right for delete_breakpoint itself as such
function should not leave stale references in the leftover data structures.
How well could be other code cleaned up with this patch in place I have not
targeted by this patch.
The existing code expects accessibility of freed memory and discusses the
current stale references problem:
void
delete_breakpoint (struct breakpoint *bpt)
[...]
/* Has this bp already been deleted? This can happen because multiple
lists can hold pointers to bp's. bpstat lists are especial culprits.
One example of this happening is a watchpoint's scope bp. When the
scope bp triggers, we notice that the watchpoint is out of scope, and
delete it. We also delete its scope bp. But the scope bp is marked
"auto-deleting", and is already on a bpstat. That bpstat is then
checked for auto-deleting bp's, which are deleted.
A real solution to this problem might involve reference counts in bp's,
and/or giving them pointers back to their referencing bpstat's, and
teaching delete_breakpoint to only free a bp's storage when no more
references were extent. A cheaper bandaid was chosen. */
if (bpt->type == bp_none)
return;
[...]
bpt->type = bp_none;
xfree (bpt);
}
While fixing this part may be difficult I find the attached patch easy enough
fixing the IMO currently most common crash due to it.
No regressions on {x86_64,x86_64-m32,i686}-fedora12-linux-gnu.
Thanks,
Jan

commit f8ca03e0097ae49c66cf33a50e3247bccd3a4a33
Author: Tom Tromey <tromey@redhat.com>
Date: Wed Apr 28 14:17:38 2010 -0600
Reimplement infrun parts of next-over-throw.
Previously, we reset the step-resume breakpoint.
However, this can do the wrong thing if an exception
is thrown and caught beneath the nexting frame.
The new approach is to have a separate exception-resume
breakpoint.
