Linux: Make __rseq_size useful for feature detection (bug 31965)

2024-07-09T17:33:37Z

The __rseq_size value is now the active area of struct rseq (so 20 initially), not the full struct size including padding at the end (32 initially). Update misc/tst-rseq to print some additional diagnostics. Reviewed-by: Michael Jeanson Reviewed-by: Mathieu Desnoyers

manual: add syscalls

2024-07-09T09:54:29Z

The purpose of this patch is to add some system calls that (1) aren't otherwise documented, and (2) are merely redirected to the kernel, so can refer to their documentation; and define a standard way of doing so in the future. A more detailed explaination of how system calls are wrapped is added along with reference to the Linux Man-Pages project. Default version of man-pages is in configure.ac but can be overridden by --with-man-pages=X.Y Reviewed-by: Alejandro Colomar

manual: Recommendations for dynamic linker hardening

2024-07-03T17:26:14Z

This new section in the manual provides recommendations for use of glibc in environments with higher integrity requirements. It's reflecting both current implementation shortcomings, and challenges we inherit from ELF and psABI requirements. Reviewed-by: Jonathan Wakely

Add --disable-static-c++-tests option [BZ #31797]

2024-07-02T07:51:34Z

By default, if the C++ toolchain lacks support for static linking, configure fails to find the C++ header files and the glibc build fails. The --disable-static-c++-link-check option allows the glibc build to finish, but static C++ tests will fail if the C++ toolchain doesn't have the necessary static C++ libraries which may not be easily installed. Add --disable-static-c++-tests option to skip the static C++ link check and tests. This fixes BZ #31797. Signed-off-by: H.J. Lu

Add --disable-static-c++-link-check option [BZ #31412]

2024-07-02T07:51:34Z

The current minimum GCC version of glibc build is GCC 6.2 or newer. But building i686 glibc with GCC 6.4 on Fedora 40 failed since the C++ header files couldn't be found which was caused by the static C++ link check failure due to missing __divmoddi4 which was referenced in i686 libc.a and added to GCC 7. Add --disable-static-c++-link-check configure option to disable the static C++ link test. The newly built i686 libc.a can be used by GCC 6.4 to create static C++ tests. This fixes BZ #31412.

Fix strnlen doc re array size

2024-06-26T15:16:05Z

* manual/string.texi: For strnlen (s, maxlen), do not say that s must be of size maxlen, as it can be smaller if it is null-terminated. This should help avoid confusion such as seen in . Mention that strnlen and wcsnlen have been in POSIX since POSIX.1-2008.
