Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jmorris/linux-security
Pull security subsystem updates from James Morris: "In this update, Smack learns to love IPv6 and to mount a filesystem with a transmutable hierarchy (i.e. security labels are inherited from parent directory upon creation rather than creating process). The rest of the changes are maintenance" * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jmorris/linux-security: (37 commits) tpm/tpm_i2c_infineon: Remove unused header file tpm: tpm_i2c_infinion: Don't modify i2c_client->driver evm: audit integrity metadata failures integrity: move integrity_audit_msg() evm: calculate HMAC after initializing posix acl on tmpfs maintainers: add Dmitry Kasatkin Smack: Fix the bug smackcipso can't set CIPSO correctly Smack: Fix possible NULL pointer dereference at smk_netlbl_mls() Smack: Add smkfstransmute mount option Smack: Improve access check performance Smack: Local IPv6 port based controls tpm: fix regression caused by section type conflict of tpm_dev_release() in ppc builds maintainers: Remove Kent from maintainers tpm: move TPM_DIGEST_SIZE defintion tpm_tis: missing platform_driver_unregister() on error in init_tis() security: clarify cap_inode_getsecctx description apparmor: no need to delay vfree() apparmor: fix fully qualified name parsing apparmor: fix setprocattr arg processing for onexec apparmor: localize getting the security context to a few macros ...
