Subject: [PATCH v3 01/27] SECURITY: selinux, fix update_rlimit_cpu parameter
Date: Sat, 28 Nov 2009 00:05:41 +0100 [thread overview]
Message-ID: <1259363167-9347-1-git-send-email-jslaby@suse.cz> (raw)
From: Jiri Slaby <jirislaby@gmail.com>
Don't pass rlim_cur member of RLIM_NLIMITS-1=RLIMIT_RTTIME limit
to update_rlimit_cpu() in selinux_bprm_committing_creds.
Use proper rlim[RLIMIT_CPU].rlim_cur instead.
