Merge branch 'next' of git://git.kernel.org/pub/scm/linux/kernel/git/jmorris/linux-security
Pull security subsystem updates from James Morris: "Highlights: - PKCS#7 support added to support signed kexec, also utilized for module signing. See comments in 3f1e1bea. ** NOTE: this requires linking against the OpenSSL library, which must be installed, e.g. the openssl-devel on Fedora ** - Smack - add IPv6 host labeling; ignore labels on kernel threads - support smack labeling mounts which use binary mount data - SELinux: - add ioctl whitelisting (see http://kernsec.org/files/lss2015/vanderstoep.pdf) - fix mprotect PROT_EXEC regression caused by mm change - Seccomp: - add ptrace options for suspend/resume" * 'next' of git://git.kernel.org/pub/scm/linux/kernel/git/jmorris/linux-security: (57 commits) PKCS#7: Add OIDs for sha224, sha284 and sha512 hash algos and use them Documentation/Changes: Now need OpenSSL devel packages for module signing scripts: add extract-cert and sign-file to .gitignore modsign: Handle signing key in source tree modsign: Use if_changed rule for extracting cert from module signing key Move certificate handling to its own directory sign-file: Fix warning about BIO_reset() return value PKCS#7: Add MODULE_LICENSE() to test module Smack - Fix build error with bringup unconfigured sign-file: Document dependency on OpenSSL devel libraries PKCS#7: Appropriately restrict authenticated attributes and content type KEYS: Add a name for PKEY_ID_PKCS7 PKCS#7: Improve and export the X.509 ASN.1 time object decoder modsign: Use extract-cert to process CONFIG_SYSTEM_TRUSTED_KEYS extract-cert: Cope with multiple X.509 certificates in a single file sign-file: Generate CMS message as signature instead of PKCS#7 PKCS#7: Support CMS messages also [RFC5652] X.509: Change recorded SKID & AKID to not include Subject or Issuer PKCS#7: Check content type and versions MAINTAINERS: The keyrings mailing list has moved ...
