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.
