From: Florent Revest <redacted> This allows other parts of the kernel (perhaps a stacked LSM allowing system monitoring, eg. the proposed KRSI LSM [1]) to retrieve the hash of a given file from IMA if it's present in the iint cache. It's true that the existence of the hash means that it's also in the audit logs or in /sys/kernel/security/ima/ascii_runtime_measurements, but it can be difficult to pull that information out for every subsequent exec. This is especially true if a given host has been up for a long time and the file was first measured a long time ago. This is based on Peter Moody's patch: https://sourceforge.net/p/linux-ima/mailman/message/33036180/ [1] https://lkml.org/lkml/2019/9/10/393 Signed-off-by: Florent Revest <redacted>Thanks for adding this Florent! Reviewed-by: KP Singh <redacted>Thanks, this patch is now queued in next-integrity-testing.
Good to hear Mimi! Thank you. I would just like to make sure that you queued the v3 of this patch though...? (this thread is for the v2 :) ) The v3 includes a couple of comments you asked for.
