LSM: SafeSetID: add setgroups() testing to selftest (2022-07-15
18:24:42 +0000)


This pull request contains one commit that touches common kernel code,

one that adds functionality internal to the SafeSetID LSM code, and a

few other commits that only modify the SafeSetID LSM selftest.

The commit that touches common kernel code simply adds an LSM hook in

the setgroups() syscall that mirrors what is done for the existing LSM

hooks in the setuid() and setgid() syscalls. This commit combined with

the SafeSetID-specific one allow the LSM to filter setgroups() calls

according to configured rule sets in the same way that is already done

for setuid() and setgid().

The changes are based on v5.19-rc6 and have been in -next.
