Subject: audit: add fchmodat2() to change attributes class
X-Git-Tag: ceph-for-7.0-rc4~352^2~4
X-Git-Url: http://git-server-git.apps.pok.os.sepia.ceph.com/?a=commitdiff_plain;h=4f493a6079b588cf1f04ce5ed6cdad45ab0d53dc;p=ceph-client.git

audit: add fchmodat2() to change attributes class

fchmodat2(), introduced in version 6.6 is currently not in the change
attribute class of audit. Calling fchmodat2() to change a file
attribute in the same fashion than chmod() or fchmodat() will bypass
audit rules such as:

-w /tmp/test -p rwa -k test_rwa

The current patch adds fchmodat2() to the change attributes class.
