Fix conditionals on mtrace-based tests (bug 31892)

2024-07-01T15:20:30Z

The conditionals for several mtrace-based tests in catgets, elf, libio, malloc, misc, nptl, posix, and stdio-common were incorrect leading to test failures when bootstrapping glibc without perl. The correct conditional for mtrace-based tests requires three checks: first checking for run-built-tests, then build-shared, and lastly that PERL is not equal to "no" (missing perl).

Revert "Test fscanf of long double without "

2024-05-24T23:24:49Z

This reverts commit 30a745450e01e4c6f484dc691c16a54a6ea72288. On ppc64le, without , vfscanf is used and with __isoc23_vfscanfieee128 is used. I am reverting this since it doesn't work on all targets.

posix: Sync tempname with gnulib

2024-04-10T17:53:39Z

The gnulib version contains an important change (9ce573cde), which fixes some problems with multithreading, entropy loss, and ASLR leak nfo. It also fixes an issue where getrandom is not being used on some new files generation (only for __GT_NOCREATE on first try). The 044bf893ac removed __path_search, which is now moved to another gnulib shared files (stdio-common/tmpdir.{c,h}). Tthis patch also fixes direxists to use __stat64_time64 instead of __xstat64, and move the include of pathmax.h for !_LIBC (since it is not used by glibc). The license is also changed from GPL 3.0 to 2.1, with permission from the authors (Bruno Haible and Paul Eggert). The sync also removed the clock fallback, since clock_gettime with CLOCK_REALTIME is expected to always succeed. It syncs with gnulib commit 323834962817af7b115187e8c9a833437f8d20ec.

Rename c2x / gnu2x tests to c23 / gnu23

2024-02-01T17:55:57Z

Complete the internal renaming from "C2X" and related names in GCC by renaming *-c2x and *-gnu2x tests to *-c23 and *-gnu23. Tested for x86_64, and with build-many-glibcs.py for powerpc64le.

Refer to C23 in place of C2X in glibc

2024-02-01T11:02:01Z

WG14 decided to use the name C23 as the informal name of the next revision of the C standard (notwithstanding the publication date in 2024). Update references to C2X in glibc to use the C23 name. This is intended to update everything *except* where it involves renaming files (the changes involving renaming tests are intended to be done separately). In the case of the _ISOC2X_SOURCE feature test macro - the only user-visible interface involved - support for that macro is kept for backwards compatibility, while adding _ISOC23_SOURCE. Tested for x86_64.

elf: Fix _dl_debug_vdprintf to work before self-relocation

2023-11-21T19:15:42Z

The strlen might trigger and invalid GOT entry if it used before the process is self-relocated (for instance on dl-tunables if any error occurs). For i386, _dl_writev with PIE requires to use the old 'int $0x80' syscall mode because the calling the TLS register (gs) is not yet initialized. Checked on x86_64-linux-gnu.

crypt: Remove libcrypt support

2023-10-30T16:03:59Z

All the crypt related functions, cryptographic algorithms, and make requirements are removed, with only the exception of md5 implementation which is moved to locale folder since it is required by localedef for integrity protection (libc's locale-reading code does not check these, but localedef does generate them). Besides thec code itself, both internal documentation and the manual is also adjusted. This allows to remove both --enable-crypt and --enable-nss-crypt configure options. Checked with a build for all affected ABIs. Co-authored-by: Zack Weinberg Reviewed-by: Carlos O'Donell
