Merge branch 'next-integrity' of git://git.kernel.org/pub/scm/linux/kernel/git/jmorris/linux-security
Pull security subsystem integrity updates from James Morris: "There is a mixture of bug fixes, code cleanup, preparatory code for new functionality and new functionality. Commit 26ddabfe96bb ("evm: enable EVM when X509 certificate is loaded") enabled EVM without loading a symmetric key, but was limited to defining the x509 certificate pathname at build. Included in this set of patches is the ability of enabling EVM, without loading the EVM symmetric key, from userspace. New is the ability to prevent the loading of an EVM symmetric key." * 'next-integrity' of git://git.kernel.org/pub/scm/linux/kernel/git/jmorris/linux-security: ima: Remove redundant conditional operator ima: Fix bool initialization/comparison ima: check signature enforcement against cmdline param instead of CONFIG module: export module signature enforcement status ima: fix hash algorithm initialization EVM: Only complain about a missing HMAC key once EVM: Allow userspace to signal an RSA key has been loaded EVM: Include security.apparmor in EVM measurements ima: call ima_file_free() prior to calling fasync integrity: use kernel_read_file_from_path() to read x509 certs ima: always measure and audit files in policy ima: don't remove the securityfs policy file vfs: fix mounting a filesystem with i_version
