The branch stable/14 has been updated by markj: URL: https://cgit.FreeBSD.org/src/commit/?id=1763deb84ba988d36546cbb6222f08a71d1a1bb0 commit 1763deb84ba988d36546cbb6222f08a71d1a1bb0 Author: Kyle Evans <kevans@FreeBSD.org> AuthorDate: 2026-06-25 17:02:47 +0000 Commit: Mark Johnston <markj@FreeBSD.org> CommitDate: 2026-06-30 17:00:22 +0000 kern: fix auditing of ptrace(2) syscall requests `error` here is the return value of syscall_thread_enter() rather than the syscall itself, so the committed audit records do not reflect reality. This is less harmful than them recording an error when the operation actually succeeded, but it could still possibly be used to throw off IDS techniques with things like bsmtrace.
