Hi Linus,
Here are the security subsystem updates for 4.14. Highlights:
AppArmor:
- Add mediation of mountpoints and signals
- Add support for absolute root view based labels
- add base infastructure for socket mediation
LSM:
- Remove unused security_task_create() hook
TPM:
- Some constification and minor updates.
IMA:
- A new integrity_read file operation method, avoids races when
calculating file hashes
SELinux:
- from Paul Moore:
"A relatively quiet period for SELinux, 11 patches with only two/three
having any substantive changes. These noteworthy changes include
another tweak to the NNP/nosuid handling, per-file labeling for
cgroups, and an object class fix for AF_UNIX/SOCK_RAW sockets; the rest
of the changes are minor tweaks or administrative updates (Stephen's
email update explains the file explosion in the diffstat)."
Seccomp:
- from Kees Cook:
"Major additions:
- sysctl and seccomp operation to discover available actions. (tyhicks)
- new per-filter configurable logging infrastructure and sysctl. (tyhicks)
- SECCOMP_RET_LOG to log allowed syscalls. (tyhicks)
- SECCOMP_RET_KILL_PROCESS as the new strictest possible action.
- self-tests for new behaviors."
And nothing for Smack, for the first time perhaps.
Please pull.
