commit 5d58f58b0d612913fd280a6acaf174019bd465ba Author: Ryan Moeller <[email protected]> AuthorDate: 2021-01-27 19:27:46 +0000 Commit: Ryan Moeller <[email protected]> CommitDate: 2021-01-29 00:36:46 +0000 sbin/sysctl: Fix CTLFLAG_SKIP for adjacent nodes The OID is saved when we encounter CTLFLAG_SKIP so that descendants can be skipped as well. We then must not update the skip OID until we are out of the node. This was achieved by resetting the skip OID once the prefix no longer matches, but the case where the OID we reset on has CTLFLAG_SKIP was not accounted for.
