https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=230619 Bug ID: 230619 Summary: pf: tables use non SMP-friendly counters Product: Base System Version: 11.2-RELEASE Hardware: Any OS: Any Status: New Severity: Affects Some People Priority: --- Component: kern Assignee: bugs@FreeBSD.org Reporter: vegeta@tuxpowered.net Created attachment 196197 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=196197&action=edit Use counter(9) in pf tables. Counters of pf tables are updated out of rule lock. That means state updates might overwrite eachother. Furthermore there is allocation and freing counters happening in lockless manner too. Proposed patch modifies table counters behaviour. counter(9) facility is used and table element counters are always allocated so that race conditions are impossible now. -- You are receiving this mail because: You are the assignee for the bug.
