Susan Hinrichs created TS-4663: ---------------------------------- Summary: ASAN crash due to scheduled event triggering after ClientSession has completed Key: TS-4663 URL: https://issues.apache.org/jira/browse/TS-4663 Project: Traffic Server Issue Type: Bug Reporter: Susan Hinrichs
Found while tracking TS-4507 and original fix combined with that fix. In ProxyClientSession::state_api_callout we schedule_in 10ms in the future if the plugin lock is not acquired. Saw ASAN use-after-free crashes when the Http2ClientSession is deleted but the schedule event remains and is triggered. Added a schedule_event member to track this case and cancel any outstanding schedule events on free. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
