22:54:12 2018 -0700 # # Merge branch 'next-integrity' of git://git.kernel.org/pub/scm/linux/kernel/git/jmorris/linux-security # # Pull integrity updates from James Morris: # "This adds support for EVM signatures based on larger digests, contains # a new audit record AUDIT_INTEGRITY_POLICY_RULE to differentiate the # IMA policy rules from the IMA-audit messages, addresses two deadlocks # due to either loading or searching for crypto algorithms, and cleans # up the audit messages" # # * 'next-integrity' of git://git.kernel.org/pub/scm/linux/kernel/git/jmorris/linux-security: # EVM: fix return value check in evm_write_xattrs() # integrity: prevent deadlock during digsig verification. # evm: Allow non-SHA1 digital signatures # evm: Don't deadlock if a crypto algorithm is unavailable # integrity: silence warning when CONFIG_SECURITYFS is not enabled # ima: Differentiate auditing policy rules from "audit" actions # ima: Do not audit if CONFIG_INTEGRITY_AUDIT is not set # ima: Use audit_log_format() rather than audit_log_string() # ima: Call audit_log_string() rather than logging it untrusted # < /opt/cross/kisskb/gcc-4.6.3-nolibc/x86_64-linux/bin/x86_64-linux-gcc --version # <
