Stefan Liebler	cc1b91eabd	S390: Fix building with --disable-mutli-arch [BZ #31196 ] Starting with commits - `7ea510127e` string: Add libc_hidden_proto for strchrnul - `22999b2f0f` string: Add libc_hidden_proto for memrchr building glibc on s390x with --disable-multi-arch fails if only the C-variant of strchrnul / memrchr is used. This is the case if gcc uses -march < z13. The build fails with: ../sysdeps/s390/strchrnul-c.c:28:49: error: ‘__strchrnul_c’ undeclared here (not in a function); did you mean ‘__strchrnul’? 28 \| __hidden_ver1 (__strchrnul_c, __GI___strchrnul, __strchrnul_c); With --disable-multi-arch, __strchrnul_c is not available as string/strchrnul.c is just included without defining STRCHRNUL and thus we also don't have to create the internal hidden symbol.

Siddhesh Poyarekar	443c10018c	Update advisory format and introduce some automation Simplify the advisory format by dropping the -Backport tags and instead stick to using just the -Commit tags. To identify backports, put a substring of git-describe into the release version in the brackets next to the commit ref. This way, it not only identifies that the fix (or regression) is on the release/2.YY/master branch, it also disambiguates regressions/fixes in the branch from those in the tarball. Add a README to make it easier for consumers to understand the format. Additionally, the Release wiki needs to be updated to inform the release manager to: 1. Generate a NEWS snipped from the advisories directory AND 2. on release/2.YY/master, replace the advisories directory with a text file pointing to the advisories directory in master so that we don't have to update multiple locations.

Arjun Shankar	7e5a0c286d	syslog: Fix heap buffer overflow in __vsyslog_internal (CVE-2023-6779) __vsyslog_internal used the return value of snprintf/vsnprintf to calculate buffer sizes for memory allocation. If these functions (for any reason) failed and returned -1, the resulting buffer would be too small to hold output. This commit fixes that.

Xi Ruoyao	dfa3394a60	qsort: Fix a typo causing unnecessary malloc/free (BZ 31276) In qsort_r we allocate a buffer sized QSORT_STACK_SIZE (1024) on stack and we intend to use it if all elements can fit into it. But there is a typo: if (total_size < sizeof buf) buf = tmp; else /* allocate a buffer on heap and use it ... */ Here "buf" is a pointer, thus sizeof buf is just 4 or 8, instead of 1024. There is also a minor issue that we should use "<=" instead of "<". This bug is detected debugging some strange heap corruption running the Ruby-3.3.0 test suite (on an experimental Linux From Scratch build using Binutils-2.41.90 and Glibc trunk, and also Fedora Rawhide [1]). It seems Ruby is doing some wild "optimization" by jumping into somewhere in qsort_r instead of calling it normally, resulting in a double free of buf if we allocate it on heap. The issue can be reproduced deterministically with: LD_PRELOAD=/usr/lib/libc_malloc_debug.so MALLOC_CHECK_=3 \ LD_LIBRARY_PATH=. ./ruby test/runner.rb test/ruby/test_enum.rb in Ruby-3.3.0 tree after building it. This change would hide the issue for Ruby, but Ruby is likely still buggy (if using this "optimization" sorting larger arrays).

Joseph Myers	b86cb494f9	Further build-many-glibcs.py fixes for utcnow() deprecation It turns out that the replacement of datetime.datetime.utcnow(), for a warning produced early in running build-many-glibcs.py with Python 3.12, (a) wasn't complete (there were other uses elsewhere in the script also needing updating) and (b) broke reading of build-time from build-state.json, because an aware datetime was written out including +00:00 for the timezone, which was not expected by the strptime call. Fix the first by making the change to datetime.datetime.now(datetime.timezone.utc) for all the remaining utcnow() calls. Fix the second by using strftime with an explicit format instead of just str() when formatting build times for build-state.json and and email subjects, and then setting the timezone explicitly when reading from build-state.json. (Other uses, in particular messages output by the bot, continue to use str() as the precise format should not matter in those cases; it shouldn't actually matter for email subjects either but it seems a good idea to keep those short.) Tested with a bot-cycle run and checking the format of times in build-state.json afterwards.	2 years ago

Daniel Cederman	7bd06985c0	sparc: Remove unwind information from signal return stubs [BZ #31244 ] The functions were previously written in C, but were not compiled with unwind information. The ENTRY/END macros includes .cfi_startproc and .cfi_endproc which adds unwind information. This caused the tests cleanup-8 and cleanup-10 in the GCC testsuite to fail. This patch adds a version of the ENTRY/END macros without the CFI instructions that can be used instead. sigaction registers a restorer address that is located two instructions before the stub function. This patch adds a two instruction padding to avoid that the unwinder accesses the unwind information from the function that the linker has placed right before it in memory. This fixes an issue with pthread_cancel that caused tst-mutex8-static (and other tests) to fail.

Adhemerval Zanella	709fbd3ec3	stdlib: Reinstate stable mergesort implementation on qsort The mergesort removal from qsort implementation (commit `03bf8357e8`) had the side-effect of making sorting nonstable. Although neither POSIX nor C standard specify that qsort should be stable, it seems that it has become an instance of Hyrum's law where multiple programs expect it. Also, the resulting introsort implementation is not faster than the previous mergesort (which makes the change even less appealing). This patch restores the previous mergesort implementation, with the exception of machinery that checks the resulting allocation against the _SC_PHYS_PAGES (it only adds complexity and the heuristic not always make sense depending on the system configuration and load). The alloca usage was replaced with a fixed-size buffer. For the fallback mechanism, the implementation uses heapsort. It is simpler than quicksort, and it does not suffer from adversarial inputs. With memory overcommit, it should be rarely triggered. The drawback is mergesort requires O(n) extra space, and since it is allocated with malloc the function is AS-signal-unsafe. It should be feasible to change it to use mmap, although I am not sure how urgent it is. The heapsort is also nonstable, so programs that require a stable sort would still be subject to this latent issue. The tst-qsort5 is removed since it will not create quicksort adversarial inputs with the current qsort_r implementation. Checked on x86_64-linux-gnu and aarch64-linux-gnu.
