Race on mutex switching for NetVConnections in UnixNetVConnection::mainEvent
----------------------------------------------------------------------------
Key: TS-1158
URL: https://issues.apache.org/jira/browse/TS-1158
Project: Traffic Server
Issue Type: Bug
Components: Core
Affects Versions: 3.0.3
Environment: ALL
Reporter: John Plevyak
Assignee: John Plevyak
Fix For: 3.1.4
Because of the way session management works, the vio.mutex must be re-verified
to be identical to the one the lock was taken on after the lock is acquired.
Otherwise there is a race when the mutex is switched allowing such that the old
lock is held while the new lock is in not held.
