Probably will want to merge #134 and rebase this before merging. |
Resolve a race condition in the PeerRemovalQueue where a removal job could be processed after a node had reconnected and its public key changed. The queue now stores the peer's public key at enqueue time and validates it against the current key before invoking RemovePeer. If the keys differ, the stale removal is skipped and a warning is logged. Added a new removalJob struct to carry the key, updated the queue logic, and introduced comprehensive unit tests (TestPeerRemovalQueueStaleRemovalSkipped and TestPeerRemovalQueueConcurrentEnqueue) to verify correct behavior. This improves reliability of WireGuard peer management during rapid reconnect scenarios. Signed-off-by: Devon Bautista <17506592+synackd@users.noreply.github.com>

Description
This PR addresses a race condition in the
PeerRemovalQueuewhere a removal job could be processed after a node had re‑connected and its public key changed. The queue now stores the peer's public key at enqueue time and validates it against the current key before invokingRemovePeer. If the keys differ, the stale removal is skipped and a warning is logged. Added a newremovalJobstruct to carry the key, updated the queue logic, and introduced comprehensive unit tests (TestPeerRemovalQueueStaleRemovalSkippedandTestPeerRemovalQueueConcurrentEnqueue) to verify correct behavior. This improves reliability of WireGuard peer management during rapid reconnect scenarios.Fixes #128 (comment)
