Pull general security subsystem updates from James Morris:
"TPM (from Jarkko):
- essential clean up for tpm_crb so that ARM64 and x86 versions do
not distract each other as much as before
- /dev/tpm0 rejects now too short writes (shorter buffer than
specified in the command header
- use DMA-safe buffer in tpm_tis_spi
- otherwise mostly minor fixes.
Smack:
- base support for overlafs
Capabilities:
- BPRM_FCAPS fixes, from Richard Guy Briggs:
The audit subsystem is adding a BPRM_FCAPS record when auditing
setuid application execution (SYSCALL execve). This is not expected
as it was supposed to be limited to when the file system actually
had capabilities in an extended attribute. It lists all
capabilities making the event really ugly to parse what is
happening. The PATH record correctly records the setuid bit and
owner. Suppress the BPRM_FCAPS record on set*id.
TOMOYO:
- Y2038 timestamping fixes"
