* fchmodat: AT_SYMLINK_NOFOLLOW fix for non-symlinksPaul Eggert2020-02-071-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fix lchmod, and fchmodat with AT_SYMLINK_NOFOLLOW, so that they act like chmod on non-symlinks. * NEWS: * doc/glibc-functions/lchmod.texi (lchmod): * doc/posix-functions/fchmodat.texi (fchmodat): Mention this. * lib/fchmodat.c: Define __need_system_sys_stat_h before including config.h, and undef it after including sys/stat.h the first time. Include fcntl.h, stdio.h, unistd.h, intprops.h, and include sys/stat.h a second time after defining orig_fchmodat. (orig_fchmodat) [HAVE_FCHMODAT]: New function. (fchmodat) [HAVE_FCHMODAT]: Work around the AT_SYMLINK_NOFOLLOW bug. * lib/lchmod.c: New file. * lib/sys_stat.in.h (fchmodat, lchmod): Support replacing these functions. * m4/fchmodat.m4 (gl_FUNC_FCHMODAT): If fchmodat exists, test that AT_SYMLINK_NOFOLLOW works on non-symlinks. * m4/lchmod.m4 (gl_FUNC_LCHMOD): Check for lstat. Test that lchmod works on non-symlinks. * m4/sys_stat_h.m4 (gl_SYS_STAT_H_DEFAULTS): Default REPLACE_FCHMODAT and REPLACE_LCHMOD to 0. * modules/fchmodat (Depends-on): Add fstatat, intprops, lchmod, unistd. (Depends-on, configure.ac): Check REPLACE_FCHMODAT too. * modules/lchmod (Files): Add lib/lchmod.c. (Depends-on): Add errno, fcntl-h, fchmodat, intprops, lstat, unistd. (configure.ac): Compile lchmod.c if needed. (lib_SOURCES): Add lchmod.c. * modules/sys_stat (sys/stat.h): Substitute REPLACE_FCHMODAT and REPLACE_LCHMOD. * tests/test-fchmodat.c: Include fcntl.h, sys/stat.h. (main): Test fchmodat with AT_SYMLINK_NOFOLLOW on non-symlinks.
