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
