This was added in 233399bce2e79e5af3b344782e9943d5f1a9cdcb just for warn_if_unused warnings rather than anything substantial. Now that we have a proper configure argument for F_S (--enable-fortify-source), just drop this entirely, to avoid conflicting with e.g. detected --enable-fortify-source finding F_S=3, then nscd's Makefile setting F_S=2, resulting in a build-failure because of the redefinition.

2023-07-19Fix getting return address in elf/tst-audit28.c.Stefan Liebler
Starting with commit 1bcfe0f732066ae5336b252295591ebe7e51c301, the test was enhanced and the object for __builtin_return_address (0) is searched with _dl_find_object. Unfortunately on e.g. s390 (31bit), a postprocessing step is needed as the highest bit has to be masked out. This can be done with __builtin_extract_return_addr. Without this postprocessing, _dl_find_object returns with -1 and the content of dlfo is invalid, which may lead to segfaults in basename. Therefore those checks are now only done on success.

2023-07-18[PATCH v1] x86: Use `3/4*sizeof(per-thread-L3)` as low bound for NT threshold.Noah Goldstein
On some machines we end up with incomplete cache information. This can make the new calculation of `sizeof(total-L3)/custom-divisor` end up lower than intended (and lower than the prior value). So reintroduce the old bound as a lower bound to avoid potentially regressing code where we don't have complete information to make the decision. Reviewed-by: DJ Delorie <dj@redhat.com>

Previously we added `core` even if `threads_l2` was invalid, and only used `threads_l2` to divide `core` if it was present. The changed version only included `core` if `threads_l2` was valid.

2023-07-12sparc: Fix la_symbind for bind-now (BZ 23734)Adhemerval Zanella
The sparc ABI has multiple cases on how to handle JMP_SLOT relocations, (sparc_fixup_plt/sparc64_fixup_plt). For BINDNOW, _dl_audit_symbind will be responsible to setup the final relocation value; while for lazy binding _dl_fixup/_dl_profile_fixup will call the audit callback and tail cail elf_machine_fixup_plt (which will call sparc64_fixup_plt). This patch fixes by issuing the SPARC specific routine on bindnow and forwarding the audit value to elf_machine_fixup_plt for lazy resolution. It fixes the la_symbind for bind-now tests on sparc64 and sparcv9: elf/tst-audit24a elf/tst-audit24b elf/tst-audit24c elf/tst-audit24d Checked on sparc64-linux-gnu and sparcv9-linux-gnu.

2023-07-06realloc: Limit chunk reuse to only growing requests [BZ #30579]Siddhesh Poyarekar
The trim_threshold is too aggressive a heuristic to decide if chunk reuse is OK for reallocated memory; for repeated small, shrinking allocations it leads to internal fragmentation and for repeated larger allocations that fragmentation may blow up even worse due to the dynamic nature of the threshold. Limit reuse only when it is within the alignment padding, which is 2 * size_t for heap allocations and a page size for mmapped allocations. There's the added wrinkle of THP, but this fix ignores it for now, pessimizing that case in favor of keeping fragmentation low. This resolves BZ #30579.
