Merge branch 'next' of git://git.kernel.org/pub/scm/linux/kernel/git/jmorris/linux-security
Pull security subsystem updates from James Morris: "New notable features: - The seccomp work from Will Drewry - PR_{GET,SET}_NO_NEW_PRIVS from Andy Lutomirski - Longer security labels for Smack from Casey Schaufler - Additional ptrace restriction modes for Yama by Kees Cook" Fix up trivial context conflicts in arch/x86/Kconfig and include/linux/filter.h * 'next' of git://git.kernel.org/pub/scm/linux/kernel/git/jmorris/linux-security: (65 commits) apparmor: fix long path failure due to disconnected path apparmor: fix profile lookup for unconfined ima: fix filename hint to reflect script interpreter name KEYS: Don't check for NULL key pointer in key_validate() Smack: allow for significantly longer Smack labels v4 gfp flags for security_inode_alloc()? Smack: recursive tramsmute Yama: replace capable() with ns_capable() TOMOYO: Accept manager programs which do not start with / . KEYS: Add invalidation support KEYS: Do LRU discard in full keyrings KEYS: Permit in-place link replacement in keyring list KEYS: Perform RCU synchronisation on keys prior to key destruction KEYS: Announce key type (un)registration KEYS: Reorganise keys Makefile KEYS: Move the key config into security/keys/Kconfig KEYS: Use the compat keyctl() syscall wrapper on Sparc64 for Sparc32 compat Yama: remove an unused variable samples/seccomp: fix dependencies on arch macros Yama: add additional ptrace scopes ...
