Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jmorris/linux-security
Pull security subsystem updates from James Morris: "Apart from reordering the SELinux mmap code to ensure DAC is called before MAC, these are minor maintenance updates" * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jmorris/linux-security: (23 commits) selinux: correctly label /proc inodes in use before the policy is loaded selinux: put the mmap() DAC controls before the MAC controls selinux: fix the output of ./scripts/get_maintainer.pl for SELinux evm: enable key retention service automatically ima: skip memory allocation for empty files evm: EVM does not use MD5 ima: return d_name.name if d_path fails integrity: fix checkpatch errors ima: fix erroneous removal of security.ima xattr security: integrity: Use a more current logging style MAINTAINERS: email updates and other misc. changes ima: reduce memory usage when a template containing the n field is used ima: restore the original behavior for sending data with ima template Integrity: Pass commname via get_task_comm() fs: move i_readcount ima: use static const char array definitions security: have cap_dentry_init_security return error ima: new helper: file_inode(file) kernel: Mark function as static in kernel/seccomp.c capability: Use current logging styles ...
