https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=260499 Bug ID: 260499 Summary: [carp] Carp unable recover after demotion by send error Product: Base System Version: CURRENT Hardware: Any OS: Any Status: New Severity: Affects Only Me Priority: --- Component: kern Assignee: bugs@FreeBSD.org Reporter: marius.halden@modirum.com Created attachment 230203 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=230203&action=edit testcase.sh When carp is demoted due to send errors it will never recover as the code path which will decrement the demotion counter appears to be dead. Expected output from test case when working: > # sh testcase.sh > Staring jail test1. > ... > carp: 1@epair1b: BACKUP -> MASTER (master timed out) > net.inet.carp.demotion: 0 > > Enabling pf > pf enabled > ... > carp: demoted by 240 to 240 (send error 13 on epair1b) > net.inet.carp.demotion: 240 > > Disabling pf > pf disabled > ....... > carp: demoted by -240 to 0 (send ok on epair1b) > net.inet.carp.demotion: 0 > Cleaning up. Actual output from test case: > # sh testcase.sh > Staring jail test1. > ... > carp: 1@epair0b: BACKUP -> MASTER (master timed out) > net.inet.carp.demotion: 0 > > Enabling pf > pf enabled > ... > carp: demoted by 240 to 240 (send error 13 on epair0b) > net.inet.carp.demotion: 240 > > Disabling pf > pf disabled > ....... > carp: demoted by 240 to 240 (send error 13 on epair0b) > net.inet.carp.demotion: 240 > Cleaning up. Note, the test case uses PF to force ip_output to fail. -- You are receiving this mail because: You are the assignee for the bug.home | help
