Hi Linus,
Two IMA changes, one EVM change, a use after free bug fix, and a code cleanup to
address "-Wflex-array-member-not-at-end" warnings:
- The existing IMA {ascii, binary}_runtime_measurements lists include a hard
coded SHA1 hash. To address this limitation, define per TPM enabled hash
algorithm {ascii, binary}_runtime_measurements lists.
- Close an IMA integrity init_module syscall measurement gap by defining a new
critical-data record.
- Enable (partial) EVM support on stacked filesystems (overlayfs). Only EVM
portable & immutable file signatures are copied up, since they do not contain
filesystem specific metadata.
thanks,
Mimi
