storage/posix: perform chmod after chown.
Problem: When a replica brick is added to a volume, set-user-ID and set-group-ID permission bits of files are not set correctly in the new brick. The issue is in the posix_setattr() call where we do a chmod followed by a chown. But according to the man pages for chown: When the owner or group of an executable file are changed by an unprivileged user the S_ISUID and S_ISGID mode bits are cleared. POSIX does not specify whether this also should happen when root does the chown(). Fix: Swap the chmod and chown calls in posix_setattr() Change-Id: I094e47a995c210d2fdbc23ae7a5718286e7a9cf8 BUG: 1058797 Signed-off-by: Ravishankar N <> Reviewed-on: Tested-by: Gluster Build System <> Reviewed-by: Pranith Kumar Karampuri <> Reviewed-by: Anand Avati <>
