* hurd: statvfs: __f_type -> f_typeнаб2023-08-081-2/+2
| | | | | | | | | No further changes needed ([f]statvfs() just cast to struct statfs * and call [f]statfs()).

* htl: Initialize ___pthread_self earlySamuel Thibault2023-08-083-17/+15
| | | | | | | | | | When using jemalloc, malloc() needs to use TSD, while libpthread initialization needs malloc(). Having ___pthread_self set early to some static storage allows TSD to work early, thus allowing jemalloc and libpthread to initialize together. This incidentaly simplifies __pthread_enable/disable_asynccancel and __pthread_self, now that ___pthread_self is always initialized.
* htl: Add support for static TSD dataSamuel Thibault2023-08-087-18/+97
| | | | | | When using jemalloc, malloc() needs to use TSD, while libpthread initialization needs malloc(). Supporting a static TSD area allows jemalloc and libpthread to initialize together.
* x86: Fix for cache computation on AMD legacy cpus.Sajan Karumanchi2023-08-061-27/+199
| | | | | | | | | | | Some legacy AMD CPUs and hypervisors have the _cpuid_ '0x8000_001D' set to Zero, thus resulting in zeroed-out computed cache values. This patch reintroduces the old way of cache computation as a fail-safe option to handle these exceptions. Fixed 'level4_cache_size' value through handle_amd().

* hurd: Rework generating errno.hSamuel Thibault2023-08-063-41/+19
| | | | | We only need to give to gawk the headers that actually define error numbers, so let's rather filter out the other included headers early.
* powerpc longjmp: Fix build after chk hidden builtin fixSamuel Thibault2023-08-041-0/+3
| | | | | | | | | | 04bf7d2d8a79 ("chk: Add and fix hidden builtin definitions for *_chk") added an #undef for longjmp and siglongjmp to compensate for the definition in include/setjmp.h, but missed doing so for the powerpc version too. Fixes: 04bf7d2d8a79 ("chk: Add and fix hidden builtin definitions for *_chk")
* LoongArch: Fix static PIE condition for toolchain bootstrapping.Yang Yujie2023-08-042-2/+2
| | | | | | This patch allows the static PIE startfile rcrt1.o to be built without requiring libgcc_s.so from GCC, which depends on libc in the first place.
* chk: Add and fix hidden builtin definitions for *_chkSamuel Thibault2023-08-036-0/+15
| | | | | | | Otherwise on gnu-i686 there are unwanted PLT entries in libc.so when fortification is enabled. Tested for i686-gnu, x86_64-gnu, i686-linux-gnu and x86_64-linux-gnu
* tst-realpath-toolong: return "unsupported" when PATH_MAX is undefinedSamuel Thibault2023-08-031-4/+5
| | | | | When PATH_MAX is undefined, realpath cannot ever ENAMETOOLONG, so this test is unsupported.
* Subject: hurd: Make __realpath return EINVAL on NULL bufSamuel Thibault2023-08-031-1/+10
| | | | | As Posix and stdlib/test-canon.c expects it, and rather than letting pathconf crash.
* tst-*glob*: Do not check d_name sizeSamuel Thibault2023-08-032-2/+2
| | | | | | | Posix says that d_name is of unspecified size, and sizeof(d_name) should not be used. It is indeed only 1-byte long in bits/dirent.h. We can instead explictly provide the actual allocated size to __strcpy_chk.
* hurd: Do not include full <stdarg.h> in <hurd.h>Florian Weimer2023-08-031-2/+2

| | | | | | | Commit 91927b7c76 ("Rewrite iconv option parsing [BZ #19519]") changed the iconv program to call __gconv_open directly instead of the iconv_open wrapper, but the former does not set errno. Update the caller to interpret the return codes like iconv_open does.

| | | | | | | | | This patch updates the kernel version in the tests tst-mman-consts.py, tst-mount-consts.py and tst-pidfd-consts.py to 6.4. (There are no new constants covered by these tests in 6.4 that need any other header changes.) Tested with build-many-glibcs.py.
* PowerPC: Influence cpu/arch hwcap features via GLIBC_TUNABLESMahesh Bodapati2023-08-0113-74/+414
| | | | | | | | | | | This patch enables the option to influence hwcaps used by PowerPC. The environment variable, GLIBC_TUNABLES=glibc.cpu.hwcaps=-xxx,yyy,-zzz...., can be used to enable CPU/ARCH feature yyy, disable CPU/ARCH feature xxx and zzz, where the feature name is case-sensitive and has to match the ones mentioned in the file{sysdeps/powerpc/dl-procinfo.c}.
