Subject: [patch 3/3] attach-fail-reasons: SELinux deny_ptrace
Hi,
and here is the last bit for new SELinux 'deny_ptrace':
https://bugzilla.redhat.com/show_bug.cgi?id=786878
As even PTRACE_TRACEME fails in such case it needs to install hook for even
that event.
Thanks,
Jan
gdb/
2012-03-06 Jan Kratochvil <jan.kratochvil@redhat.com>
* common/linux-ptrace.c [HAVE_SELINUX_SELINUX_H]: include
selinux/selinux.h.
(linux_ptrace_attach_warnings): Call linux_ptrace_create_warnings.
(linux_ptrace_create_warnings): New.
* common/linux-ptrace.h (linux_ptrace_create_warnings): New declaration.
* config.in: Regenerate.
* configure: Regenerate.
* configure.ac: Check selinux/selinux.h and the selinux library.
* inf-ptrace.c (inf_ptrace_me): Check the ptrace result.
* linux-nat.c (linux_nat_create_inferior): New variable ex. Wrap
to_create_inferior into TRY_CATCH, call linux_ptrace_create_warnings.
gdb/gdbserver/
* config.in: Regenerate.
* configure: Regenerate.
* configure.ac: Check selinux/selinux.h and the selinux library.
* linux-low.c (linux_traceme): New function.
(linux_create_inferior, linux_tracefork_child): Call it instead of
direct ptrace.

Subject: [patch 2/3] case insensitive: re_comp->regcomp
Hi,
re_comp cannot be passed REG_ICASE. Therefore change the code. The should
have no functionality impact.
The new boolean field `preg_p' could be maybe replaced by a conditional
`preg.buffer != NULL' which would work with libiberty regcomp implementation
but I do not see it guaranteed anywhere. GDB is always using static libiberty
implementation which I do not see why in the case it is running on glibc.
But if it gets fixed one day and it starts to use externally linked
regcomp/regexec I would find the `preg.buffer != NULL' conditional dangerous.
Thanks,
Jan

* symtab.c (struct search_symbols_data): New fields preg, preg_p.
(search_symbols_name_matches): Use them, use regexec.
(search_symbols): New variable retval_chain, adjust the use of
old_chain against it. Replace re_comp by regcomp. Use the new struct
search_symbols_data fields, use regexec instead of re_exec.

Subject: [patch] testsuite: Test readline-6.2 "ask" regression
Hi,
this problem does not affect default FSF GDB build as it is using bundled
readline-5.1. But with system readline-6.2 and build using:
--with-system-readline use installed readline library
GDB will no longer ask about displaying too many symbols and dumps them all
immediately.
PASS:
$ gdb gdb
(gdb) p <tab><tab>
Display all 21482 possibilities? (y or n)_
FAIL:
$ gdb gdb
(gdb) p <tab><tab>
Display all 22129 possibilities? (y or n)
../../bfd/aout-target.h cs_to_section
../../bfd/aout32.c ctime
<screens and screens of dumps without any question>
This regression will soon start affecting distros:
FSF GDB HEAD - PASS - using bundled readline-5.1
fedora-15 - FAIL - using system readline-6.2
fedora-14 - PASS - using system readline-6.1
debian-6.0 - PASS - using system readline-6.1
kubuntu-10.10 - PASS - using system readline-6.1
I have asked about it on readline ml:
Re: [Bug-readline] callback mode pager disable status
https://lists.gnu.org/archive/html/bug-readline/2011-04/msg00012.html
The suggested workaround (in fact the readline-5.1 code state) going to patch
into the proposed FSF GDB bundled readline-6.2. Distros then can stop using
--with-system-readline to still feature recent and system matching readline
until readline-7.0 gets released.
This regression has been so far caught only with system debug infos installed:
-PASS: gdb.base/completion.exp: complete (2) 'p no_var_named_this-'
-PASS: gdb.base/completion.exp: complete 'p values[0].a'
-PASS: gdb.base/completion.exp: complete 'p values[0] . a'
-PASS: gdb.base/completion.exp: complete 'p &values[0] -> a'
-PASS: gdb.base/completion.exp: copmletion of field in anonymous union
+FAIL: gdb.base/completion.exp: (timeout) complete (2) 'p no_var_named_this-'
+FAIL: gdb.base/completion.exp: (timeout) complete 'p values[0].a' 2
+FAIL: gdb.base/completion.exp: (timeout) complete 'p values[0] . a' 2
+FAIL: gdb.base/completion.exp: (timeout) complete 'p &values[0] -> a' 2
+FAIL: gdb.base/completion.exp: copmletion of field in anonymous union
I will check it in with no comments.

Hi,
this is mostly unrelated. But after the patch 2/3 it will still FAIL:
Loaded symbols for /lib64/ld-linux-x86-64.so.2
Cannot find new threads: debugger service failed
(gdb) FAIL: gdb.threads/gcore-thread.exp: re-load generated corefile
as it is a common bug I dislike for years I have fixed it here:
Loaded symbols for /lib64/ld-linux-x86-64.so.2
Cannot find new threads: debugger service failed
Core was generated by `.../gdb/testsuite/gdb.threads/gcore-thread'.
Program terminated with signal 5, Trace/breakpoint trap.

Is there a reason for it? With recent Fedora 17 update
https://bugzilla.redhat.com/show_bug.cgi?id=635651
dejagnu has started to support 'find_gfortran'. But it still does not support
'find_go_linker'. This has resulted in regression failing to compile any
gdb.go/*.exp files.

For example `break error' does not work for debugging GDB with gcc-4.6.x.
As gcc-4.6.0 and now even 4.6.1 still has this bug and I have seen a user(s?)
on non-Fedora platform asking about this bug and as there may be enough
binaries out there (although it affects only -O0 -g compilation) coded it
properly I have coded the workaround properly this time.
It does not solve overlays well, but the code just does not work for overlays,
it has no other negative effect.
I will update the code after FSF gcc gets fixed to minimize the workaround.
No regressions on {x86_64,x86_64-m32,i686}-fedora16pre-linux-gnu.
I would welcome a comment whether it is suitable for FSF GDB.
Thanks,
Jan

Subject: [patch] Workaround buggy GCC PR 47510 produced code
Hi,
GCC PR debug/47510 is already fixed and GDB has the proper support for it:
RFC: update for GCC PR 47510
http://sourceware.org/ml/gdb-patches/2011-03/msg00916.html
Still FSF GDB HEAD will crash on a binary produced by older/buggy GCC:
Reading symbols from .../gcc46.o...dwarf2read.c:9329: internal-error: could not find partial DIE 0x9a in cache [from module .../gcc46.o]
Which may not give much clue to the user.
The proposed patch could make false warnings if any code out there has
DW_TAG_typedef with children, it does not check for specific GCC versions.
Still such DWARF is invalid, although in such case complaint() would be more
appropriate than warning(). Does it make sense to differentiate it?
No regressions on {x86_64,x86_64-m32,i686}-fedora15-linux-gnu.
Thanks,
Jan

Subject: [RFA] Fix inconsistency in blockvector addrmap vs non-addrmap handling
Hi.
I was seeing the assert in dw2_find_pc_sect_psymtab trigger
and traced it to the fact that when pending_addrmap_interesting gets
set blockvector.map is used instead of blockvector.block.
The difference is that blockvector.block contains entries for the global
and static blocks whereas pending_addrmap doesn't.
This patch fixes this by making them consistent.
I suspect more work is necessary (e.g. can symtabs "overlap" even though
the individual pieces do not?).
But I first want to fix the regression introduced by the change
to dw2_find_pc_sect_psymtab: There is more code in a symtab than is
documented by function and lexical block pc ranges (e.g. C++ method thunks).
Regression tested on amd64-linux, and by verifying the assert no longer
triggers in the testcase I was using.
Ok to commit?
Note that this obviates the need for the patch in:

Subject: [RFA/commit 1/3] Revert "Search global symbols from the expression's block objfile first."
The search order used in this patch breaks global symbol lookups
for certain symbols when copy-relocation is used. A slightly different
search order will be implemented later.
gdb/ChangeLog:
Revert the following patch:
* findvar.c (default_read_var_value): For LOC_UNRESOLVED symbols,
try locating the symbol in the symbol's own objfile first, before
extending the search to all objfiles.
* symtab.c (lookup_symbol_aux_objfile): New function, extracted
out of lookup_symbol_aux_symtabs.
(lookup_symbol_aux_symtabs): Add new parameter "exclude_objfile".
Replace extracted-out code by call to lookup_symbol_aux_objfile.
Do not search EXCLUDE_OBJFILE.
(lookup_static_symbol_aux): Update call to lookup_symbol_aux_symtabs.
(lookup_symbol_global): Search for matches in the block's objfile
first, before searching all other objfiles.
Will commit if patches #2 & #3 are OK.

So far GDB expected all such displacements will be always PAGE_SIZE aligned.
This applies for example for re-prelinking of an already prelinked file.
But it does not apply for prelinking of an unprelinked file or unprelinking of
a prelinked file, there can be arbitrary displacement.
It affects i386 (=i686, prelink doc reports also ARM and MIPS) which uses REL.
x86_64 always uses RELA, therefore I have not noticed it so far. i386 still
has to be supported.
This affects both attachment to a PID and core file loads.
This applies in real world if you transfer a core file between hosts and try to
backtrace them, libraries of both hosts may differ whether they are / are not
prelinked.
I could implement some (displacement-forgiving and prelink-modifications
forgiving) comparison of both DYNAMIC segments found. But I do not think it is
useful, if the DYNAMIC address from linkmap vs. bfd do not match it is still a
better chance to try a displacement to make them match. Keeping the file
relocation cannot work anyway when the DYNAMIC address is verified as wrong.
No regressions on {x86_64,x86_64-m32,i686}-fedora15-linux-gnu.
Mostly do you agree the DYNAMIC content does not have to be verifed?
Do you have any comments on the in-code long comments?
Thanks,
Jan

The correct way would be:
make check//unix RUNTESTFLAGS='CC_FOR_TARGET=gcc\ -fPIC\ -pie CXX_FOR_TARGET=g++\ -fPIC\ -pie solib-display.exp'
But there is a problem with testsuite.unix non-unique subdir name and also
a problem with make -j parallelization of the testsuite.

Subject: [downstream patch FYI] workaround stale frame_info * (PR 13866)
Hi,
I did not look at which commit caused this regression but apparently it was
introduced at least with multi-inferiors.
I understand this fix is not right fix of the crash; but in most GDB cases one
does not use multi-inferior so why to regress single-inferior by it.
Some more simple solutions still fix the single-inferior mode but they
regressed the multi-inferior mode
gdb.threads/no-unwaited-for-left.exp
gdb.multi/base.exp
so I had to put there that sorting magic.
With proper C++ sanity check of stale live frame_info references the testcase
would be simple without the "frame_garbage_collection" reproducer below.
It is also reproducible just with valgrind but regularly running the whole
testsuite under valgrind I did not find feasible.
No regressions on {x86_64,x86_64-m32,i686}-fedora17-linux-gnu.
Thanks,
Jan

Subject: [commit 2/2] testsuite: code_elim.exp: Fix false FAIL
Hi,
with Fedora 18 x86_64 (Rawhide) there is a false FAIl since:
2167931cf70f91206efb8b01e848a55d82a347ce is the first bad commit
Author: Tom Tromey <tromey@redhat.com>
Date: Fri May 18 15:31:39 2012 +0000
http://sourceware.org/bugzilla/show_bug.cgi?id=13907
print &my_global_symbol
-$1 = (int *) 0x804a004
-(gdb) PASS: gdb.base/code_elim.exp: get address of my_global_symbol
+$1 = (int *) 0x804a004 <completed.5732>
+(gdb) FAIL: gdb.base/code_elim.exp: get address of my_global_symbol
Nothing really changed, just GDB now prints <completed.5732> and the testcase
expects either none or <my_global_symbol> suffix.
This is because the two symbol files (their sections .data/.bss) have
overlapped so GDB chooses randomly which symbol to display. And since
Fedora 18 GCC puts there that "completed.5732" symbol.
This may be because add-symbol-file FILE ADDR relocates to ADDR on the .text
section and leaves other sections at their original place, which is IMO a bit
unexpected; it is a FAQ people expect more ADDR to be relocation displacement
(and not relative to .text and not limited to .text). But this is really
outside of the scope of this testcase false FAIL.
Checked in.
Thanks,
Jan

Subject: [patch 1/2] Fix gdb.cp/gdb2495.exp regression with gcc-4.7 #5
Hi,
posted as a new thread.
As described in
cancel: [patch] Fix gdb.cp/gdb2495.exp regression with gcc-4.7 #4 [Re: [revert] Regression on PowerPC]
http://sourceware.org/ml/gdb-patches/2012-03/msg00322.html
just ON_STACK had some regressions.
The expectations in that mail were wrong (at least that cleanup/fix is not
required for gdb.cp/gdb2495.exp).
The problem is that the inferior call return pad breakpoint instruction is
never removed even after inferior call finishes. It is even still visible in
"maintenance info breakpoints". This does not matter much for AT_ENTRY_POINT
but for ON_STACK it just corrupts stack.
No regressions on
{x86_64,x86_64-m32,i686}-fedora(15-rawhide)/rhel(5-6)-linux-gnu and for
gdbsever non-extended mode.
Thanks,
Jan

Subject: [patch 2/2] Fix gdb.cp/gdb2495.exp regression with gcc-4.7 #5
Hi,
here is the ON_STACK code again, with fixed alignment for i386 SSE.
It is generalized for all OSes on i386/amd64. I can move it to
{i386,amd64)-linux-tdep.c but I find this code much more lightweight than
i386_push_dummy_call which is already present in i386-tdep.
No regressions on
{x86_64,x86_64-m32,i686}-fedora(15-rawhide)/rhel(5-6)-linux-gnu and for
gdbsever non-extended mode.
For x86_64-fedora17-linux-gnu it fixes:
-FAIL: gdb.cp/gdb2495.exp: Call a function that raises an exception without a handler.
-FAIL: gdb.cp/gdb2495.exp: bt after returning from a popped frame
+PASS: gdb.cp/gdb2495.exp: Call a function that raises an exception without a handler.
+PASS: gdb.cp/gdb2495.exp: bt after returning from a popped frame
