Re: [PATCH 1/1] signal: Adjust error codes according to restore_user_sigmask()

by Eric Wong

It's been 2 weeks and this fix hasn't appeared in mmots / mmotm. I also noticed it's missing Cc: for stable@ (below) Deepa Dinamani <deepa.kernel(a)gmail.com> wrote: > For all the syscalls that receive a sigmask from the userland, > the user sigmask is to be in effect through the syscall execution. > At the end of syscall, sigmask of the current process is restored > to what it was before the switch over to user sigmask. > But, for this to be true in practice, the sigmask should be restored > only at the the point we change the saved_sigmask.

It will be too difficult to backport this patch to stable trees, so the Fixes: tag should just be removed. I will resubmit this series without it. Steve

The issue is very similar to the fix in commit 6b0868c820ff ("mm/compaction.c: correct zone boundary handling when resetting pageblock skip hints"). When isolating free pages around a target pageblock, the boundary handling is off by one and can stray into the next pageblock. Triggering the syzbot error requires that the end of pageblock is section or zone aligned, and that the next section is unpopulated. A more subtle consequence of the bug is that pageblocks were being improperly used as migration targets which potentially hurts fragmentation avoidance in the long-term one page at a time. A debugging patch revealed that it's definitely possible to stray outside of a pageblock which is not intended. While syzbot cannot be used to verify this patch, it was confirmed that the debugging warning no longer triggers with this patch applied. It has also been confirmed that the THP allocation stress tests are not degraded by this patch.
