https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=278171 Bug ID: 278171 Summary: Reproducible kernel crash on 14.0-RELEASE and 14.0-STABLE Product: Base System Version: 14.0-RELEASE Hardware: Any OS: Any Status: New Severity: Affects Some People Priority: --- Component: kern Assignee: bugs@FreeBSD.org Reporter: thomas.dreibholz@gmail.com Created attachment 249709 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=249709&action=edit PCAP trace of the SCTP communication I made some tests with rsplib (https://github.com/dreibh/rsplib) on freshly installed FreeBSD VMs (14.0-RELEASE and 14.0-STABLE) under VirtualBox as well as Proxmox. With the following simple steps, I can reproducibly crash all these systems: Build: git clone https://github.com/dreibh/rsplib cd rsplib cmake . -DENABLE_QT=OFF make cd src ./rspregistrar In another shell, or on another machine in the same network: ./rspserver => crash with reboot Background: rspserver finds rspregistrar by its ASAP Announces via UDP. Then, it establishes an SCTP association via SCTP 1-to-many-style socket calls. For the established association to rspregistrar, it calls sctp_peeloff() to get a new socket descriptor. I suspect that something is wrong here with SCTP, leading to the crash. Attachments: * A PCAP trace on another machine, where rspregistrar had been started, in order to get a PCAP trace up to the crash. -- You are receiving this mail because: You are the assignee for the bug.home | help
