Oliver Hartkopp 540dff311c can: isotp: fix error path in isotp_sendmsg() to unlock wait queue ... commit 8375dfac4f upstream. Commit 43a08c3bda ("can: isotp: isotp_sendmsg(): fix TX buffer concurrent access in isotp_sendmsg()") introduced a new locking scheme that may render the userspace application in a locking state when an error is detected. This issue shows up under high load on simultaneously running isotp channels with identical configuration which is against the ISO specification and therefore breaks any reasonable PDU communication anyway.
