SECURITY: selinux, fix update_rlimit_cpu parameter
Jiri Slaby [Fri, 28 Aug 2009 08:47:16 +0000 (10:47 +0200)]
Don't pass current RLIMIT_RTTIME to update_rlimit_cpu() in
selinux_bprm_committing_creds, since update_rlimit_cpu expects
RLIMIT_CPU limit.

Use proper rlim[RLIMIT_CPU].rlim_cur instead to fix that.
