This is the fourth revision of the LSM initialization rework patchset. The number of changes between this revision and the last are limited to a rework of the lsm_read() function and the replacement of my IMA/EVM patch with one from Roberto; relatively minor things given the scope of the patchset.
I've run the v4 patchset through some basic testing today and everything looks okay to me; I'll continue to play with it, but I wanted to get this out onto the list sooner rather than later. Assuming Mimi is okay with Roberto's patch, and no other issues are found, I would expect this to go into the LSM tree after the upcoming merge window closes. For those of you having problems pulling this patchset into your own local trees for review/testing, this patchset can be found in the working-lsm_init_rework branch of the main LSM tree: https://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/lsm.git/log/?h=working-lsm_init_rework The RFC/v3 patchset: https://lore.kernel.org/linux-security-module/20250814225159.275901-36-p...@paul-moore.com/ The RFC/v2 patchset: https://lore.kernel.org/linux-security-module/20250721232142.77224-36-p...@paul-moore.com/ The RFC/v1 patchset is below, the cover letter provides some background and motivation for this series which still applies: https://lore.kernel.org/linux-security-module/20250409185019.238841-31-p...@paul-moore.com/ CHANGELOG v4: -
