[gdb] Fix data race in bitfield
Data race between:
...
Write of size 4 at 0x7b8009b483f0 by thread T2:
#0 set_type_align(type*, unsigned long) /home/vries/gdb_versions/devel/src/gdb/gdbtypes.c:3751 (gdb+0x961e08)
...
and:
...
Previous read of size 1 at 0x7b8009b483f1 by thread T4:
#0 type::instance_flags() const /home/vries/gdb_versions/devel/src/gdb/gdbtypes.h:1092 (gdb+0x59e74b)
...
corresponding to:
...
unsigned align_log2 : TYPE_ALIGN_BITS;
unsigned m_instance_flags : 9;
...
Fix this by wrapping them using "struct { ... };".
For now, don't worry about size increase, we might have to address this later
using packed.
Still, is this a correct fix? Maybe the problem is modifying a type from
different thread. If so, having this patch for now may expose that problem.

For now, just do a malloc in get_print_cell to work around the data race.

and "set debug dwarf-read 1" (dumped into a log file, see V), I noticed:
...

[dwarf-read] process_queue: Expanding symtabs of objfile cc1, queue size: 1 ...

[dwarf-read] process_queue: Expanding symtabs of objfile cc1, queue size: 172 ...
...
that the queue processed by process_queue can be large, and is processed
sequentially, and I wondered if doing this in parallel might speed things up.
This might also be useful for -readnow, but that might require additional
changes to active this, I haven't checked that yet.
II. Correctness results.
The running example runs without thread sanitizer issues.
Running the testsuite with thread sanitizer revealed issues during
cpexprs-debug-types.exp.
III. Performance results.
I did a performance experiment using:
...
$ for n in $(seq 1 10); do \
time gdb -q -batch ~/firefox/libxul.so-93.0-1.1.x86_64.debug \
2>&1 \
| grep "real:"; \
done
...
and observed the following results for master:
...
real: 4.09
real: 4.03
real: 4.64
real: 4.04
real: 4.18
real: 4.73
real: 4.63
real: 4.02
real: 4.04
real: 4.03
...
and with this branch:
...
real: 4.04
real: 4.06
real: 3.97
real: 4.59
real: 4.39
real: 4.03
real: 4.03
real: 3.96
real: 3.97
real: 4.54
...
which looks roughtly comparable, so we don't seem to have slowed down the
common case (where we don't excercise process_queue yet).
Then with the running example:
...
$ for n in $(seq 1 10); do \
time gdb -q -batch ./lto/cc1 -ex "b do_rpo_vn" 2>&1 | grep "real:"; \
done
...
with master:
...
real: 4.19
real: 4.40
real: 4.30
real: 4.29
real: 4.20
real: 4.25
real: 4.28
real: 4.22
real: 4.31
real: 4.32
...
and this branch:
...
real: 4.79
real: 4.83
real: 4.81
real: 4.74
real: 4.93
real: 4.92
real: 4.72
real: 4.82
real: 4.77
real: 4.79
...
So, there's a noticable slowdown.
Doing the break after "maint set worker-threads 0" (to force the parallel for
in process_queue to run sequentially) gives us:
...
real: 4.56
real: 4.50
real: 4.57
real: 4.57
real: 4.61
real: 4.58
real: 4.52
real: 4.62
real: 4.52
real: 4.58
...
IV. Analysis.
The slowdown is probably caused by excessive locking. This could be solved by
tracking more things in a thread_local way, but probably at the cost of more
memory.
We could implement a statistics_mutex that dumps the lock/unlock statistics
upon destroying to find out what the problematic locks are (I suspect at least
the die_type ones).
A possibility is that we're not getting the full benefit because we only start
processing in parallel once process_queue is called. A possible fix
would be to have the main thread filling the queue and a dispatcher thread
reading it and dispatching items to worker threads.
Another possibility is that we're not getting the full benefit because we
fairly distribute a number of CUs, but CUs will not be of equal size (this
might hold equally for the cooked index btw). This could be mitigated
somewhat by taking into account the size of the CUs when doing the
distribution. Another solution would be to add a parallel_for_each_dynamic or
some such that dispatches to workers that are idle. [ Presumably the
dispatcher thread mentioned above would behave similarly. ]
[ I've proposed a patch "[gdbsupport] Use task size in parallel_for_each" for
trunk that deals with this issue for the parallel for in
dwarf2_build_psymtabs_hard. Included in this branch before the cover letter. ]
[ A last minute addition "[gdb/symtab] Use task size in parallel for in
process_queue" did not improve the result. ]

[gdbsupport] Use task size in parallel_for_each
Ensuring a fair distribution over the worker threads and main thread in terms
of number of CUs might not be the most efficient way, given that CUs can vary
in size.
Fix this by:
- adding a task_size_ptr parameter to parallel_for_each,
defaulting to nullptr,
- using per_cu->get_length () as the task size in the parallel_for_each
in dwarf2_build_psymtabs_hard, and
- using the task size in parallel_for_each to distribute similarly-sized tasks
to the threads.
I've used this experiment to verify the performance impact:
...
$ for n in $(seq 1 10); do \
time gdb -q -batch ~/firefox/libxul.so-93.0-1.1.x86_64.debug \
2>&1 \
| grep "real:"; \
done
...
and without the patch got:
...
real: 4.71
real: 4.88
real: 4.29
real: 4.30
real: 4.65
real: 4.27
real: 4.27
real: 4.27
real: 4.75
real: 4.41
...
and with the patch:
...
real: 3.68
real: 3.81
real: 3.80
real: 3.68
real: 3.75
real: 3.69
real: 3.69
real: 3.74
real: 3.67
real: 3.74
...
so that seems a reasonable improvement.
With parallel_for_each_debug set to true, we get some more detail about
the difference in behaviour. Without the patch we have:
...
Parallel for: n_elements: 2818
Parallel for: minimum elements per thread: 1
Parallel for: elts_per_thread: 704
Parallel for: elements on worker thread 0 : 705
Parallel for: elements on worker thread 1 : 705
Parallel for: elements on worker thread 2 : 704
Parallel for: elements on worker thread 3 : 0
Parallel for: elements on main thread : 704
...
and with the patch:
...
Parallel for: n_elements: 2818
Parallel for: total_size: 1483674865
Parallel for: size_per_thread: 370918716
Parallel for: elements on worker thread 0 : 752 (size: 371811790)
Parallel for: elements on worker thread 1 : 360 (size: 371509370)
Parallel for: elements on worker thread 2 : 1130 (size: 372681710)
Parallel for: elements on worker thread 3 : 0 (size: 0)

[gdb/symtab] Fix bad compile unit index complaint
I noticed this code in dw2_debug_names_iterator::next:
...
case DW_IDX_compile_unit:
/* Don't crash on bad data. */
if (ull >= per_bfd->all_comp_units.size ())
{
complaint (_(".debug_names entry has bad CU index %s"
" [in module %s]"),
pulongest (ull),
objfile_name (objfile));
continue;
}
per_cu = per_bfd->get_cu (ull);
break;
...
This code used to DTRT, before we started keeping both CUs and TUs in
all_comp_units.
Fix by using "per_bfd->all_comp_units.size () - per_bfd->tu_stats.nr_tus"
instead.
It's hard to produce a test-case for this, but let's try at least to trigger
the complaint somehow. We start out by creating an exec with .debug_types and
.debug_names:
...
$ gcc -g ~/hello.c -fdebug-types-section
$ gdb-add-index -dwarf-5 a.out
...
and verify that we don't see any complaints:
...
$ gdb -q -batch -iex "set complaints 100" ./a.out
...
We look at the CU and TU table using readelf -w and conclude that we have
nr_cus == 6 and nr_tus == 1.
Now override ull in dw2_debug_names_iterator::next for the DW_IDX_compile_unit
case to 6, and we have:
...
$ gdb -q -batch -iex "set complaints 100" ./a.out
During symbol reading: .debug_names entry has bad CU index 6 [in module a.out]
...
After this, it still crashes because this code in
dw2_debug_names_iterator::next:
...
/* Skip if already read in. */
if (m_per_objfile->symtab_set_p (per_cu))
goto again;
...
is called with per_cu == nullptr.
Fix this by skipping the entry if per_cu == nullptr.
Now revert the fix and observe that the complaint disappears, so we've
confirmed that the fix is required.
A somewhat similar issue for .gdb_index in dw2_symtab_iter_next has been filed
as PR29367.
Tested on x86_64-linux, with native and target board cc-with-debug-names.

PR29370, infinite loop in display_debug_abbrev
The PR29370 testcase is a fuzzed object file with multiple .trace_abbrev sections. Multiple .trace_abbrev or .debug_abbrev sections are not a violation of the DWARF standard. The DWARF5 standard even gives an example of multiple .debug_abbrev sections contained in groups. Caching and lookup of processed abbrevs thus needs to be done by section and offset rather than base and offset. (Why base anyway?) Or, since section contents are kept, by a pointer into the contents. PR 29370 * dwarf.c (struct abbrev_list): Replace abbrev_base and abbrev_offset with raw field.

binutils/dwarf.c: abbrev caching
I'm inclined to think that abbrev caching is counter-productive. The time taken to search the list of abbrevs converted to internal form is non-zero, and it's easy to decode the raw abbrevs. It's especially silly to cache empty lists of decoded abbrevs (happens with zero padding in .debug_abbrev), or abbrevs as they are displayed when there is no further use of those abbrevs. This patch stops caching in those cases. * dwarf.c (record_abbrev_list_for_cu): Add free_list param.

Handle Python 3.11 deprecation of PySys_SetPath and Py_SetProgramName
Python 3.11 deprecates PySys_SetPath and Py_SetProgramName. The
PyConfig API replaces these and other functions. This commit uses the
PyConfig API to provide equivalent functionality while also preserving
support for older versions of Python, i.e. those before Python 3.8.
A beta version of Python 3.11 is available in Fedora Rawhide. Both
Fedora 35 and Fedora 36 use Python 3.10, while Fedora 34 still used
Python 3.9. I've tested these changes on Fedora 34, Fedora 36, and
rawhide, though complete testing was not possible on rawhide due to
a kernel bug. That being the case, I decided to enable the newer
PyConfig API by testing PY_VERSION_HEX against 0x030a0000. This
corresponds to Python 3.10.
We could try to use the PyConfig API for Python versions as early as 3.8,
but I'm reluctant to do this as there may have been PyConfig related
bugs in earlier versions which have since been fixed. Recent linux
distributions should have support for Python 3.10. This should be
more than adequate for testing the new Python initialization code in
GDB.
Information about the PyConfig API as well as the motivation behind
deprecating the old interface can be found at these links:
https://github.com/python/cpython/issues/88279
https://peps.python.org/pep-0587/
https://docs.python.org/3.11/c-api/init_config.html
The v2 commit also addresses several problems that Simon found in
the v1 version.
In v1, I had used Py_DontWriteBytecodeFlag in the new initialization
code, but Simon pointed out that this global configuration variable
will be deprecated in Python 3.12. This version of the patch no longer
uses Py_DontWriteBytecodeFlag in the new initialization code.
Additionally, both Py_DontWriteBytecodeFlag and Py_IgnoreEnvironmentFlag
will no longer be used when building GDB against Python 3.10 or higher.
While it's true that both of these global configuration variables are
deprecated in Python 3.12, it makes sense to disable their use for
gdb builds against 3.10 and higher since those are the versions for
which the PyConfig API is now being used by GDB. (The PyConfig API
includes different mechanisms for making the same settings afforded
by use of the soon-to-be deprecated global configuration variables.)
Simon also noted that PyConfig_Clear() would not have be called for
one of the failure paths. I've fixed that problem and also made the
rest of the "bail out" code more direct. In particular,
PyConfig_Clear() will always be called, both for success and failure.
The v3 patch addresses some rebase conflicts related to module
initialization . Commit

Don't stop all threads prematurely after first step of "step N"
In all-stop mode, when the target is itself in non-stop mode (like
GNU/Linux), if you use the "step N" (or "stepi/next/nexti N") to step
a thread a number of times:
(gdb) help step
step, s
Step program until it reaches a different source line.
Usage: step [N]
Argument N means step N times (or till program stops for another reason).
... GDB prematurely stops all threads after the first step, and
doesn't re-resume them for the subsequent N-1 steps. It's as if for
the 2nd and subsequent steps, the command was running with
scheduler-locking enabled.
This can be observed with the testcase added by this commit, which
looks like this:
static pthread_barrier_t barrier;
static void *
thread_func (void *arg)
{
pthread_barrier_wait (&barrier);
return NULL;
}
int
main ()
{
pthread_t thread;
int ret;
pthread_barrier_init (&barrier, NULL, 2);
/* We run to this line below, and then issue "next 3". That should
step over the 3 lines below and land on the return statement. If
GDB prematurely stops the thread_func thread after the first of
the 3 nexts (and never resumes it again), then the join won't
ever return. */
pthread_create (&thread, NULL, thread_func, NULL); /* set break here */
pthread_barrier_wait (&barrier);
pthread_join (thread, NULL);
return 0;
}
The test hangs and times out without the GDB fix:
(gdb) next 3
[New Thread 0x7ffff7d89700 (LWP 525772)]
FAIL: gdb.threads/step-N-all-progress.exp: non-stop=off: target-non-stop=on: next 3 (timeout)
The problem is a core gdb bug.
When you do "step/stepi/next/nexti N", GDB internally creates a
thread_fsm object and associates it with the stepping thread. For the
stepping commands, the FSM's class is step_command_fsm. That object
is what keeps track of how many steps are left to make. When one step
finishes, handle_inferior_event calls stop_waiting and returns, and
then fetch_inferior_event calls the "should_stop" method of the event
thread's FSM. The implementation of that method decrements the
steps-left counter. If the counter is 0, it returns true and we
proceed to presenting the stop to the user. If it isn't 0 yet, then
the method returns false, indicating to fetch_inferior_event to "keep
going".
Focusing now on when the first step finishes -- we're in "all-stop"
mode, with the target in non-stop mode. When a step finishes,
handle_inferior_event calls stop_waiting, which itself calls
stop_all_threads to stop everything. I.e., after the first step
completes, all threads are stopped, before handle_inferior_event
returns. And after that, now in fetch_inferior_event, we consult the
thread's thread_fsm::should_stop, which as we've seen, for the first
step returns false -- i.e., we need to keep_going for another step.
However, since the target is in non-stop mode, keep_going resumes
_only_ the current thread. All the other threads remain stopped,
inadvertently.
If the target is in non-stop mode, we don't actually need to stop all
threads right after each step finishes, and then re-resume them again.
We can instead defer stopping all threads until all the steps are
completed.
So fix this by delaying the stopping of all threads until after we
called the FSM's "should_stop" method. I.e., move it from
stop_waiting, to handle_inferior_events's callers,
fetch_inferior_event and wait_for_inferior.
New test included. Tested on x86-64 GNU/Linux native and gdbserver.

gas/symbols: introduce md_resolve_symbol
Assuming GMSD is a special operand, marked as O_md1, the code:
.set VREG, GMSD
.set REG, VREG
extsw REG, 2
...fails upon attempts to resolve the value of the symbol. This happens
since machine-dependent values are not handled in the giant op switch.
We introduce a custom md_resolve_symbol macro; the ports can use this
macro to customize the behavior when resolve_symbol_value hits O_md
operand.

x86: Disallow invalid relocations against protected symbols
Since glibc 2.36 will issue warnings for copy relocation against protected symbols and non-canonical reference to canonical protected functions, change the linker to always disallow such relocations. bfd/ * elf32-i386.c (elf_i386_scan_relocs): Remove check for elf_has_indirect_extern_access. * elf64-x86-64.c (elf_x86_64_scan_relocs): Likewise. (elf_x86_64_relocate_section): Remove check for elf_has_no_copy_on_protected. * elfxx-x86.c (elf_x86_allocate_dynrelocs): Check for building executable instead of elf_has_no_copy_on_protected. (_bfd_x86_elf_adjust_dynamic_symbol): Disallow copy relocation against non-copyable protected symbol. * elfxx-x86.h (SYMBOL_NO_COPYRELOC): Remove check for elf_has_no_copy_on_protected. ld/ * testsuite/ld-i386/i386.exp: Expect linker error for PR ld/17709 test. * testsuite/ld-i386/pr17709.rd: Removed. * testsuite/ld-i386/pr17709.err: New file. * testsuite/ld-x86-64/pr17709.rd: Removed. * testsuite/ld-x86-64/pr17709.err: New file. * testsuite/ld-x86-64/pr28875-func.err: Updated. * testsuite/ld-x86-64/x86-64.exp: Expect linker error for PR ld/17709 test. Add tests for function pointer against protected function. |

x86: Make protected symbols local for -shared
Call _bfd_elf_symbol_refs_local_p with local_protected==true. This has
2 noticeable effects for -shared:
* GOT-generating relocations referencing a protected data symbol no
longer lead to a GLOB_DAT (similar to a hidden symbol).
* Direct access relocations (e.g. R_X86_64_PC32) no longer has the
confusing diagnostic below.
__attribute__((visibility("protected"))) void *foo() {
return (void *)foo;
}
// gcc -fpic -shared -fuse-ld=bfd
relocation R_X86_64_PC32 against protected symbol `foo' can not be used when making a shared object
The new behavior matches arm, aarch64 (commit

[AArch64] MTE corefile support
Teach GDB how to dump memory tags for AArch64 when using the gcore command and how to read memory tag data back from a core file generated by GDB (via gcore) or by the Linux kernel. The format is documented in the Linux Kernel documentation [1]. Each tagged memory range (listed in /proc/<pid>/smaps) gets dumped to its own PT_AARCH64_MEMTAG_MTE segment. A section named ".memtag" is created for each of those segments when reading the core file back. To save a little bit of space, given MTE tags only take 4 bits, the memory tags are stored packed as 2 tags per byte. When reading the data back, the tags are unpacked. I've added a new testcase to exercise the feature. Build-tested with --enable-targets=all and regression tested on aarch64-linux Ubuntu 20.04.

[AArch64] Support AArch64 MTE memory tag dumps in core files
The Linux kernel can dump memory tag segments to a core file, one segment per mapped range. The format and documentation can be found in the Linux kernel tree [1]. The following patch adjusts bfd and binutils so they can handle this new segment type and display it accordingly. It also adds code required so GDB can properly read/dump core file data containing memory tags. Upon reading, each segment that contains memory tags gets mapped to a section named "memtag". These sections will be used by GDB to lookup the tag data. There can be multiple such sections with the same name, and they are not numbered to simplify GDB's handling and lookup. There is another patch for GDB that enables both reading and dumping of memory tag segments. Tested on aarch64-linux Ubuntu 20.04.

Add gdb.free_objfile event registry
Currently, Python code can use event registries to detect when gdb loads a new objfile, and when gdb clears the objfile list. However, there's no way to detect the removal of an objfile, say when the inferior calls dlclose. This patch adds a gdb.free_objfile event registry and arranges for an event to be emitted in this case. |

Put gdb.base/bt-on-fatal-signal.exp GDB cores in output dir
I noticed that gdb.base/bt-on-fatal-signal.exp was contributing four core files to the count of unexpected core files: $ make check TESTS="gdb.base/bt-on-fatal-signal.exp" === gdb Summary === # of unexpected core files 4 # of expected passes 21 These are GDB core dumps. They are expected, however, because the whole point of the testcase is to crash GDB with a signal. Make GDB change its current directory to the output dir just before crashing, so that the core files end up there. The result is now: === gdb Summary === # of expected passes 25 and: $ find . -name "core.*" ./testsuite/outputs/gdb.base/bt-on-fatal-signal/core.gdb.1676506.nelson.1657727692 ./testsuite/outputs/gdb.base/bt-on-fatal-signal/core.gdb.1672585.nelson.1657727671 ./testsuite/outputs/gdb.base/bt-on-fatal-signal/core.gdb.1674833.nelson.1657727683 ./testsuite/outputs/gdb.base/bt-on-fatal-signal/core.gdb.1673709.nelson.1657727676 (Note the test is skipped at the top if on a remote host.)

Remove array typedef assumption for Ada
Currently the Ada code assumes that it can distinguish between a multi-dimensional array and an array of arrays by looking for an intervening typedef -- that is, for an array of arrays, there will be a typedef wrapping the innermost array type. A recent compiler change removes this typedef, which causes a gdb failure in the internal AdaCore test suite. This patch handles this case by checking whether the array type in question has a name. |
