Subject: [PATCH 6/6] file capabilities: remove needless (?) bprm_clear_caps calls
Date: Fri, 26 Sep 2008 22:27:51 -0400	[thread overview]
Message-ID: <1222482472-12847-2-git-send-email-serue@us.ibm.com> (raw)
In-Reply-To: <d57038cdc6b35c2522771e8ed5d5d59ce991a6e1.1222451103.git.serue@us.ibm.com>

Andrew Morgan, if you have a moment, please do take a close look
and make sure I'm not doing anything stupid/wrong in the cleanups!
However ltp shows no difference with and without the patchset.

Following are the kernel sizes after some of the patches.

original, pre-patch, with file capabilities compiled out:
   text    data     bss     dec     hex filename
4188468  234432  316472 4739372  48512c vmlinux

original, pre-patch, with file capabilities compiled in:
4189356  234432  316472 4740260  4854a4 vmlinux

plain with fcaps always-on:
4189392  234456  316472 4740320  4854e0 vmlinux

with non-inline cap_safe_nice:
4189112  234456  316472 4740040  4853c8 vmlinux

with cleaned-up setcap:
4189120  234456  316472 4740048  4853d0 vmlinux

with needless check for target!=current removed from cap_capset:
4189104  234456  316472 4740032  4853c0 vmlinux

with needless(?) bprm_clear_caps calls removed:
4189088  234456  316472 4740016  4853b0 vmlinux


thanks,
-serge
