https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D230619 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=3D196197&action= =3Dedit 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 count= ers happening in lockless manner too. Proposed patch modifies table counters behaviour. counter(9) facility is us= ed and table element counters are always allocated so that race conditions are impossible now. --=20 You are receiving this mail because: You are the assignee for the bug.=
