The first patch might be a bit controversial, but the second is a rather straightforward fix; more on both below. The first fix from Casey addresses a problem that should have been caught during the ~16 month (?) review cycle, but sadly was not. The good news is that Dmitry caught it very quickly once Linux v6.8 was released. The core issue is the use of size_t parameters to pass buffer sizes back and forth in the syscall; while we could have solved this with a compat syscall definition, given the newness of the syscalls I wanted to attempt to just redefine the size_t parameters as u32 types and avoid the work associated with a set of compat syscalls. However, this is technically a change in the syscall's signature/API so I can understand if you're opposed to this, even if the syscalls are less than a week old. [ Fingers crossed nobody even notices - Linus ] The second fix is a rather trivial fix to allow userspace to call into the lsm_get_self_attr() syscall with a NULL buffer to quickly determine a minimum required size for the buffer. We do have kselftests for this very case, I'm not sure why I didn't notice the failure; I'm going to guess stupidity, tired eyes, I dunno. My apologies we didn't catch this earlier" * tag 'lsm-pr-20240314' of git://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/lsm: lsm: handle the NULL buffer case in lsm_fill_user_ctx() lsm: use 32-bit compatible data types in LSM syscalls |
