Subject: [PATCH] Avoid buffer overflow in ada_decode
A bug report pointed out a buffer overflow in ada_decode, which Keith
helpfully analyzed. ada_decode had a logic error when the input was
all digits. While this isn't valid -- and would probably only appear
in fuzzer tests -- it still should be handled properly.
This patch adds a missing bounds check. Tested with the self-tests in
an asan build.

Subject: [PATCH] Verify COFF symbol stringtab offset
This patch addresses an issue with malformed/fuzzed debug information that
was recently reported in gdb/30639. That bug specifically deals with
an ASAN issue, but the reproducer provided by the reporter causes a
another failure outside of ASAN:

---------------------
A fatal error internal to GDB has been detected, further
debugging is not possible. GDB will now terminate.
This is a bug, please report it. For instructions, see:
<https://www.gnu.org/software/gdb/bugs/>.
Segmentation fault (core dumped)
The issue here is that the COFF offset for the fuzzed symbol's
name is outside the string table. That is, the offset is greater
than the actual string table size.
coffread.c:getsymname actually contains a FIXME about this, and that's
what I've chosen to address to fix this issue, following what is done
in the DWARF reader:
$ ./gdb --data-directory data-directory -nx -q UAF_2
Reading symbols from /home/keiths/UAF_2...
COFF Error: string table offset (256) outside string table (length 0)
(gdb)
Unfortunately, I haven't any idea how else to test this patch since
COFF is not very common anymore. GCC removed support for it five
years ago with GCC 8.

Subject: [PATCH] gdb: warn unused result for bfd IO functions
Reference:https://sourceware.org/bugzilla/show_bug.cgi?id=30641
Conflict:in gdb/coff-pe-read.c gdb/coffread.c gdb/dbxread.c gdb/xcoffread.c:
caused by commit:
98badbfdc (Use gdb_bfd_ref_ptr in objfile):
The type of the 'obfd' member in struct 'objfile' is changed from
'bfd *' to 'gdb_bfd_ref_ptr', needs to get the 'obfd' pointer by
using the get() method.
226f9f4fa (Rename bfd_bread and bfd_bwrite):
Only rename bfd_bread and bfd_bwrite to bfd_read and bfd_write.
6cb06a8cd (Unify gdb printf functions):
unify the printf family of functions by using gdb_printf.
We still using fprintf_unfiltered here.
This fixes the compilation warnings introduced by my bfdio.c patch.
The removed bfd_seeks in coff_symfile_read date back to 1994, commit
7f4c859520, prior to which the file used stdio rather than bfd to read
symbols. Since it now uses bfd to read the file there should be no
need to synchronise to bfd's idea of the file position. I also fixed
a potential uninitialised memory access.

Subject: [PATCH] Fix gdb/coffread.c build on 32bit architectures
Reference:https://sourceware.org/git/?p=binutils-gdb.git;a=commit;h=91df9a6f810bca02883dae9275715b4960ea02f0
Conflict:NA
The getsymname function tries to emit an error using %ld for an
uintptr_t argument. Use PRIxPTR instead. Which works on any architecture
for uintptr_t.

From FEDORA_PATCHES Mon Sep 17 00:00:00 2001

Subject: gdb-6.5-sharedlibrary-path.patch
;; Fix TLS symbols resolving for shared libraries with a relative pathname.
;; The testsuite needs `gdb-6.5-tls-of-separate-debuginfo.patch'.
;;=fedoratest: One should recheck if it is really fixed upstream.
If you provided some relative path to the shared library, such as with
export LD_LIBRARY_PATH=.
then gdb would fail to match the shared library name during the TLS lookup.
Dropped the workaround/fix for gdb-6.8.50.20081128 - is it still needed?
The testsuite needs `gdb-6.3-bz146810-solib_absolute_prefix_is_empty.patch'.
The testsuite needs `gdb-6.5-tls-of-separate-debuginfo.patch'.
2006-09-01 Jan Kratochvil <jan.kratochvil@redhat.com>
* solib-svr4.c (svr4_fetch_objfile_link_map): Match even absolute
requested pathnames to the internal loaded relative pathnames.
2007-10-16 Jan Kratochvil <jan.kratochvil@redhat.com>
Port to GDB-6.7.

From eb6d8345fb21aa4eba9b02289645f3265c02175b Mon Sep 17 00:00:00 2001

Subject: [PATCH] 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 3acd9a692dd ("Make 'import gdb.events' work")
uses PyImport_ExtendInittab instead of PyImport_AppendInittab. That
commit also initializes a struct for each module to import. Both the
initialization and the call to were moved ahead of the ifdefs to avoid
having to replicate (at least some of) the code three times in various
portions of the ifdefs.

Subject: [PATCH] Make 'import gdb.events' work
Pierre-Marie noticed that, while gdb.events is a Python module, it
can't be imported. This patch changes how this module is created, so
that it can be imported, while also ensuring that the module is always
visible, just as it was in the past.
This new approach required one non-obvious change -- when running
gdb.base/warning.exp, where --data-directory is intentionally not
found, the event registries can now be nullptr. Consequently, this
patch probably also requires

Subject: gdb-fortran-frame-string.patch
;; Display Fortran strings in backtraces.
;;=fedoratest
http://sourceware.org/ml/gdb-patches/2014-07/msg00709.html
Hi,
for Fortran it fixes displaying normal strings also in frames/backtraces:
(gdb) frame
->
The patch is simple and I do not see why it should not be this way.
For C/C++ TYPE_CODE_STRING is not used. I am not aware of Pascal but that
language is currently not really much supported in GDB anyway.
This was a part of my archer/jankratochvil/vla branch but it is not a part of
the Intel VLA patchset as it in fact is completely unrelated to "VLA".
No regressions on {x86_64,x86_64-m32,i686}-fedora22pre-linux-gnu.
Thanks,
Jan

*** Makeinfo is too old. Info documentation will not be built.
then I checked the version of makeinfo, it said,
======
$ makeinfo --version
texi2any (GNU texinfo) 7.0.1

======
After digging a little bit, it became quite obvious that a dot is
missing in regexp that makes it impossible to match versions higher than
7.0, and here's the solution:
- | egrep 'texinfo[^0-9]*(6\.[3-9]|[7-9][0-9])' >/dev/null 2>&1; then
+ | egrep 'texinfo[^0-9]*(6\.[3-9]|[7-9]\.[0-9])' >/dev/null 2>&1; then
However, Eli pointed out that the solution above has another problem: it
will stop working when Texinfo 10.1 will be released. Meanwhile, he
suggested to solve this problem permanently. That is, we don't care
about the minor version for Texinfo > 6.9, we only care about the major
version.
In this way, the problem will be resolved permanently, thanks to Eli.
libctf/ChangeLog:
* configure: Regenerated.
* configure.ac: Update regexp to match versions higher than 7.0.

Subject: gdb-rhbz-2232086-cpp-ify-mapped-symtab.patch
;; Back-port upstream commit acc117b57f7 as part of a fix for
;; non-deterministic gdb-index generation (RH BZ 2232086).
gdb: C++-ify mapped_symtab from dwarf2/index-write.c
Make static the functions add_index_entry, find_slot, and hash_expand,
member functions of the mapped_symtab class.
Fold an additional snippet of code from write_gdbindex into
mapped_symtab::minimize, this code relates to minimisation, so this
seems like a good home for it.
Make the n_elements, data, and m_string_obstack member variables of
mapped_symtab private. Provide a new obstack() member function to
provide access to the obstack when needed, and also add member
functions begin(), end(), cbegin(), and cend() so that the
mapped_symtab class can be treated like a contained and iterated
over.
I've also taken this opportunity to split out the logic for whether
the hash table (m_data) needs expanding, this is the new function
hash_needs_expanding. This will be useful in a later commit.
There should be no user visible changes after this commit.

;; non-deterministic gdb-index generation (RH BZ 2232086).
gdb: generate dwarf-5 index identically as worker-thread count changes
Similar to the previous commit, this commit ensures that the dwarf-5
index files are generated identically as the number of worker-threads
changes.
Building the dwarf-5 index makes use of a closed hash table, the
bucket_hash local within debug_names::build(). Entries are added to
bucket_hash from m_name_to_value_set, which, in turn, is populated
by calls to debug_names::insert() in write_debug_names. The insert
calls are ordered based on the entries within the cooked_index, and
the ordering within cooked_index depends on the number of worker
threads that GDB is using.
My proposal is to sort each chain within the bucket_hash closed hash
table prior to using this to build the dwarf-5 index.
The buckets within bucket_hash will always have the same ordering (for
a given GDB build with a given executable), and by sorting the chains
within each bucket, we can be sure that GDB will see each entry in a
deterministic order.
I've extended the index creation test to cover this case.

Subject: gdb-rhbz-2232086-generate-gdb-index-consistently.patch
;; Back-port upstream commit aff250145af as part of a fix for
;; non-deterministic gdb-index generation (RH BZ 2232086).
gdb: generate gdb-index identically regardless of work thread count
It was observed that changing the number of worker threads that GDB
uses (maintenance set worker-threads NUM) would have an impact on the
layout of the generated gdb-index.
The cause seems to be how the CU are distributed between threads, and
then symbols that appear in multiple CU can be encountered earlier or
later depending on whether a particular CU moves between threads.
I certainly found this behaviour was reproducible when generating an
index for GDB itself, like:
gdb -q -nx -nh -batch \
-eiex 'maint set worker-threads NUM' \
-ex 'save gdb-index /tmp/'
And then setting different values for NUM will change the generated
index.
Now, the question is: does this matter?
I would like to suggest that yes, this does matter. At Red Hat we
generate a gdb-index as part of the build process, and we would
ideally like to have reproducible builds: for the same source,
compiled with the same tool-chain, we should get the exact same output
binary. And we do .... except for the index.
Now we could simply force GDB to only use a single worker thread when
we build the index, but, I don't think the idea of reproducible builds
is that strange, so I think we should ensure that our generated
indexes are always reproducible.
To achieve this, I propose that we add an extra step when building the
gdb-index file. After constructing the initial symbol hash table
contents, we will pull all the symbols out of the hash, sort them,
then re-insert them in sorted order. This will ensure that the
structure of the generated hash will remain consistent (given the same
set of symbols).
I've extended the existing index-file test to check that the generated
index doesn't change if we adjust the number of worker threads used.
Given that this test is already rather slow, I've only made one change
to the worker-thread count. Maybe this test should be changed to use
a smaller binary, which is quicker to load, and for which we could
then try many different worker thread counts.

gdb: reduce size of generated gdb-index file
I noticed in passing that out algorithm for generating the gdb-index
file is incorrect. When building the hash table in add_index_entry we
count every incoming entry rehash when the number of entries gets too
large. However, some of the incoming entries will be duplicates,
which don't actually result in new items being added to the hash
table.
As a result, we grow the gdb-index hash table far too often.
With an unmodified GDB, generating a gdb-index for GDB, I see a file
size of 90M, with a hash usage (in the generated index file) of just
2.6%.
With a patched GDB, generating a gdb-index for the _same_ GDB binary,
I now see a gdb-index file size of 30M, with a hash usage of 41.9%.
This is a 67% reduction in gdb-index file size.
Obviously, not every gdb-index file is going to see such big savings,
however, the larger a program, and the more symbols that are
duplicated between compilation units, the more GDB would over count,
and so, over-grow the index.
The gdb-index hash table we create has a minimum size of 1024, and
then we grow the hash when it is 75% full, doubling the hash table at
that time. Given this, then we expect that either:
a. The hash table is size 1024, and less than 75% full, or
b. The hash table is between 37.5% and 75% full.
I've include a test that checks some of these constraints -- I've not
bothered to check the upper limit, and over full hash table isn't
really a problem here, but if the fill percentage is less than 37.5%
then this indicates that we've done something wrong (obviously, I also
check for the 1024 minimum size).

;; description: 'C++ (and objc): Internal error on unqualified name
;; re-set', PR 11657] (RH BZ 1186476).
;;=fedoratest
Comments from Sergio Durigan Junior:
The "proper" fix for this whole problem would be to backport the
"ambiguous linespec" patch series. However, it is really not
recommended to do that for RHEL GDB, because the patch series is too
big and could introduce unwanted regressions. Instead, what we
chose to do was to replace the gdb_assert call by a warning (which
allows the user to continue the debugging session), and tell the
user that, although more than one location was found for his/her
breakpoint, only one will be used.

;; Back-port upstream commit 1f0fab7ff86 as part of a fix for
;; non-deterministic gdb-index generation (RH BZ 2232086).
gdb/testsuite: small refactor in selftest-support.exp
Split out the code that makes a copy of the GDB executable ready for
self testing into a new proc. A later commit in this series wants to
load the GDB executable into GDB (for creating an on-disk debug
index), but doesn't need to make use of the full do_self_tests proc.
There should be no changes in what is tested after this commit.

Subject: gdb-rhbz2250652-avoid-PyOS_ReadlineTState.patch
gdb/python: avoid use of _PyOS_ReadlineTState
In python/py-gdb-readline.c we make use of _PyOS_ReadlineTState,
however, this variable is no longer public in Python 3.13, and so GDB
no longer builds.
We are making use of _PyOS_ReadlineTState in order to re-acquire the
Python Global Interpreter Lock (GIL). The _PyOS_ReadlineTState
variable is set in Python's outer readline code prior to calling the
user (GDB) supplied readline callback function, which for us is
gdbpy_readline_wrapper. The gdbpy_readline_wrapper function is called
without the GIL held.
Instead of using _PyOS_ReadlineTState, I propose that we switch to
calling PyGILState_Ensure() and PyGILState_Release(). These functions
will acquire the GIL based on the current thread. I think this should
be sufficient; I can't imagine why we'd be running
gdbpy_readline_wrapper on one thread on behalf of a different Python
thread.... that would be unexpected I think.

From FEDORA_PATCHES Mon Sep 17 00:00:00 2001

Subject: gdb-rhbz2257562-cp-namespace-null-ptr-check.patch
;; Backport potential fix for RH BZ 2257562.
Fix printing of global variable stubs if no inferior is running
Since 3c45e9f915ae4aeab7312d6fc55a947859057572 gdb crashes when trying
to print a global variable stub without a running inferior, because of
a missing nullptr-check (the block_scope function took care of that
check before it was converted to a method).
With this check it works again:
```
(gdb) print s
$1 = <incomplete type>
```

;; Hack for proper PIE run of the testsuite.
;;=fedoratest
make check//unix/-fPIE/-pie RUNTESTFLAGS=solib-display.exp
gcc -fpic -c -fPIE -pie -o x.o x.c
/usr/lib/gcc/x86_64-redhat-linux/4.6.1/../../../../lib64/Scrt1.o: In function `_start':
(.text+0x20): undefined reference to `main'
=> Change the order for overrides.
One has to also use -fPIC rather than -fPIE, -fPIC is stronger.
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.
