Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jmorris/selinux-2.6
* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jmorris/selinux-2.6: security: compile capabilities by default selinux: make selinux_set_mnt_opts() static SELinux: Add warning messages on network denial due to error SELinux: Add network ingress and egress control permission checks NetLabel: Add auditing to the static labeling mechanism NetLabel: Introduce static network labels for unlabeled connections SELinux: Allow NetLabel to directly cache SIDs SELinux: Enable dynamic enable/disable of the network access checks SELinux: Better integration between peer labeling subsystems SELinux: Add a new peer class and permissions to the Flask definitions SELinux: Add a capabilities bitmap to SELinux policy version 22 SELinux: Add a network node caching mechanism similar to the sel_netif_*() functions SELinux: Only store the network interface's ifindex SELinux: Convert the netif code to use ifindex values NetLabel: Add IP address family information to the netlbl_skbuff_getattr() function NetLabel: Add secid token support to the NetLabel secattr struct NetLabel: Consolidate the LSM domain mapping/hashing locks NetLabel: Cleanup the LSM domain hash functions NetLabel: Remove unneeded RCU read locks
