https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=268832 Bug ID: 268832 Summary: panics in check_uidgid() for outgoing packets Product: Base System Version: 13.1-RELEASE Hardware: amd64 OS: Any Status: New Severity: Affects Only Me Priority: --- Component: kern Assignee: bugs@FreeBSD.org Reporter: email@example.com Created attachment 239348 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=239348&action=edit kgdb -n last; bt Hi! Several days ago I was update of my FreeBSD from 12.3 to 13.1 and got the next trouble: After boot fully updated OS(with packages), the OS freeze without any comments. I didn't have a chance to get some information about error or safely power off the system. It was fully freezed. OS was binary updated by freebsd-update. Freezing also repeated after switching to 13.1-RELENG kernel, builded from sources. After some time of troubleshooting and help from colleagues, got some idea about the reasons of this error. Presumably, it was some component of ipfw. In attachments is ipfw show output, There a few lines at the beginning of rules is a counts, automatically added by cbsdd. In FreeBSD 12.3 they worked without errors, but after upgrade led to the described problem. When I disabling this cbsdd function, OS working well and dont try to freeze. To be more specific, I will describe the well-reproducing event, where I get an freezing. After compiling kernel with debug options I got a possibility to saw a reason of freeze. With debug kernel system stopped freezing, showed me kernel panic message and rebooted OS. In attachments I will rest backtrace of this event. Sequencing: Booting updated OS (without jails and any VMs, only primitive service apps), starting jail with a postgres (its can stable work a long time) starting jail with a zabbix-server (that start to interact with a postgres jail) after 10-60 seconds after launch of zabbix jail I get kernel panic. I can easily repeat sequencing and get panic again to collect more information, if it needed. -- You are receiving this mail because: You are the assignee for the bug.
