* Annotate additional APIs with GCC attribute access.Martin Sebor2021-05-061-4/+6
| | | | | | | | | | | | | | | | This change continues the improvements to compile-time out of bounds checking by decorating more APIs with either attribute access, or by explicitly providing the array bound in APIs such as tmpnam() that expect arrays of some minimum size as arguments. (The latter feature is new in GCC 11.) The only effects of the attribute and/or the array bound is to check and diagnose calls to the functions that fail to provide a sufficient number of elements, and the definitions of the functions that access elements outside the specified bounds. (There is no interplay with _FORTIFY_SOURCE here yet.) Tested with GCC 7 through 11 on x86_64-linux.
* Update STATX_ATTR_DAX value from Linux 5.10.Joseph Myers2021-01-111-1/+1
| | | | | | | | This patch updates the value of STATX_ATTR_DAX in bits/statx-generic.h for a change made in Linux 5.10. (As with previous such changes, this only does anything if glibc is being used with old kernel headers.) Tested for x86_64.
* Update copyright dates with scripts/update-copyrightsPaul Eggert2021-01-026-6/+6
| | | | | | | | | | | | | | | | I used these shell commands: ../glibc/scripts/update-copyrights $PWD/../gnulib/build-aux/update-copyright (cd ../glibc && git commit -am"[this commit message]") and then ignored the output, which consisted lines saying "FOO: warning: copyright statement not found" for each of 6694 files FOO. I then removed trailing white space from benchtests/bench-pthread-locks.c and iconvdata/tst-iconv-big5-hkscs-to-2ucs4.c, to work around this diagnostic from Savannah: remote: *** pre-commit check failed ... remote: *** error: lines with trailing whitespace found remote: error: hook declined to update refs/heads/master
* nonstring: Enable __FORTIFY_LEVEL=3Siddhesh Poyarekar2020-12-311-8/+10
| | | | | Use __builtin_dynamic_object_size in the remaining functions that don't have compiler builtins as is the case for string functions.
* Add new STATX_* constants from Linux 5.8 to bits/statx-generic.h.Joseph Myers2020-08-191-0/+3
| | | | | | | | | | | | This patch adds the new STATX_MNT_ID, STATX_ATTR_MOUNT_ROOT and STATX_ATTR_DAX macros from Linux 5.8 to glibc's bits/statx-generic.h. (As with previous such changes, this only does anything if glibc is being used with old kernel headers.) A comment in the Linux kernel headers indicates that STATX_ALL is deliberately not being changed. Tested for x86_64.
* Add STATX_ATTR_VERITY from Linux 5.5 to bits/statx-generic.h.Joseph Myers2020-02-131-0/+1
| | | | | | | | This patch adds the new STATX_ATTR_VERITY macro from Linux 5.5 to glibc's bits/statx-generic.h. (This only does anything if glibc is being used with old kernel headers.) Tested for x86_64.

* <sys/stat.h>: Use Linux UAPI header for statx if available and usefulFlorian Weimer2019-06-124-69/+152

* linux: open and openat ignore 'mode' with O_TMPFILE in flagsEric Rannaud2015-02-241-9/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Both open and openat load their last argument 'mode' lazily, using va_arg() only if O_CREAT is found in oflag. This is wrong, mode is also necessary if O_TMPFILE is in oflag. By chance on x86_64, the problem wasn't evident when using O_TMPFILE with open, as the 3rd argument of open, even when not loaded with va_arg, is left untouched in RDX, where the syscall expects it. However, openat was not so lucky, and O_TMPFILE couldn't be used: mode is the 4th argument, in RCX, but the syscall expects its 4th argument in a different register than the glibc wrapper, in R10. Introduce a macro __OPEN_NEEDS_MODE (oflag) to test if either O_CREAT or O_TMPFILE is set in oflag. Tested on Linux x86_64.
