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this is a more conservative variant superseded by: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

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.

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.

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

Fix crash on reading wrong function declaration DWARF.

Pre-fill all TYPE_FIELD_TYPEs. Move nparams and iparams initialization
more close to their use.

commit 96c23bfd2863bcca7388653a7bc4c9f8a64a03be
Author: Ulrich Weigand <uweigand@de.ibm.com>
Date: Fri Feb 26 12:48:17 2010 +0000
* dwarf2loc.c (struct piece_closure): Remove ARCH member,
add ADDR_SIZE member.
(allocate_piece_closure): Update.
(copy_pieced_value_closure): Likewise.
(dwarf2_evaluate_loc_desc): Likewise.
(read_pieced_value): Use DWARF address size instead of
GDB's gdbarch_addr_bit as size of values on the DWARF stack.

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,

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

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.)

Fix re-run of PIE executable.
* solib-svr4.c (svr4_relocate_main_executable) <symfile_objfile>: Remove
the part of pre-set SYMFILE_OBJFILE->SECTION_OFFSETS.

Fix re-run of PIE executable.
* gdb.base/break-interp.exp (test_ld): Turn off "disable-randomization".
Remove $displacement_main to match the solib-svr4.c change. New "kill"
and re-"run" of the inferior.
