Subject: [GIT PULL] linux-integrity patches for Linux 4.17
Date: Sun, 25 Mar 2018 13:46:25 -0400 [thread overview]
Message-ID: <1521999985.3541.32.camel@linux.vnet.ibm.com> (raw)
Hi James,
This pull request contains a mixture of bug fixes, code cleanup, and
continues to close IMA-measurement, IMA-appraisal, and IMA-audit gaps.
Closing measurement, appraisal, and audit gaps:
- A new LSM hook named security_cred_getsecid is defined in order to
validate a file's integrity based on the credentials of the process
going to being executed, not of the existing process.
- Fuse filesystems are inherently untrusted. Instead of always re-
evaluating files, this pull request differentiates between privileged
and unprivileged mounts, and defines a new builtin policy to fail file
signature verification even on privileged mounted filesystems.
Code cleanup:
- Support for verifying a file's integrity based on an appended
signature (scripts/sign-file) is coming along really nicely. This
pull request includes some of the cleanup patches from the appended
signature patch series.
thanks,
Mimi
