The branch releng/15.0 has been updated by markj: URL: https://cgit.FreeBSD.org/src/commit/?id=f887a2c04c9ec09c468f6bb0dd510588bf5b1225 commit f887a2c04c9ec09c468f6bb0dd510588bf5b1225 Author: Kyle Evans <kevans@FreeBSD.org> AuthorDate: 2026-06-25 17:02:47 +0000 Commit: Mark Johnston <markj@FreeBSD.org> CommitDate: 2026-06-30 02:32:58 +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.
