Pull security subsystem updates from James Morris: "The main change in this kernel is Casey's generalized LSM stacking work, which removes the hard-coding of Capabilities and Yama stacking, allowing multiple arbitrary "small" LSMs to be stacked with a default monolithic module (e.g. SELinux, Smack, AppArmor). See https://lwn.net/Articles/636056/ This will allow smaller, simpler LSMs to be incorporated into the mainline kernel and arbitrarily stacked by users. Also, this is a useful cleanup of the LSM code in its own right" * 'next' of git://git.kernel.org/pub/scm/linux/kernel/git/jmorris/linux-security: (38 commits) tpm, tpm_crb: fix le64_to_cpu conversions in crb_acpi_add() vTPM: set virtual device before passing to ibmvtpm_reset_crq tpm_ibmvtpm: remove unneccessary message level. ima: update builtin policies ima: extend "mask" policy matching support ima: add support for new "euid" policy condition ima: fix ima_show_template_data_ascii() Smack: freeing an error pointer in smk_write_revoke_subj() selinux: fix setting of security labels on NFS selinux: Remove unused permission definitions selinux: enable genfscon labeling for sysfs and pstore files selinux: enable per-file labeling for debugfs files. selinux: update netlink socket classes signals: don't abuse __flush_signals() in selinux_bprm_committed_creds() selinux: Print 'sclass' as string when unrecognized netlink message occurs Smack: allow multiple labels in onlycap Smack: fix seq operations in smackfs ima: pass iint to ima_add_violation() ima: wrap event related data to the new ima_event_data structure integrity: add validity checks for 'path' parameter ...
