[PATCH 0/5] Handle seccomp notification preemption

[PATCH 1/5] seccomp: Refactor notification handler to prepare for new semantics

This refactors the user notification code to have a do / while loop around the completion condition. This has a small change in semantic, in that previously we ignored addfd calls upon wakeup if the notification had been responded to, but instead with the new change we check for an outstanding addf

[PATCH 2/5] seccomp: Add wait_killable semantic to seccomp user notifier

The user notifier feature allows for filtering of seccomp notifications in userspace. While the user notifier is handling the syscall, the notifying process can be preempted, thus ending the notification. This has become a growing problem, as Golang has adopted signal based async preemption[1]. In

[PATCH 3/5] selftests/seccomp: Add test for wait killable notifier

This adds a test for the positive case of the wait killable notifier, in testing that when the feature is activated the process acts as expected -- in not terminating on a non-fatal signal, and instead queueing it up. There is already a test case for normal handlers and preemption. Signed-off-by:
