While you're at it... I did some work on proof-of-concept LSM patches for
kdbus some time ago, see [1][2].  Currently, these are completely of date.

 [1] https://github.com/lmctl/linux/commits/kdbus-lsm-v4.for-systemd-v212
 [2] https://github.com/lmctl/kdbus/commit/aa0885489d19be92fa41c6f0a71df28763228a40

May I ask if you guys have your own plan for LSM or maybe it would be
worth to resurrect [1]?

Cheers,
