Bug ID: 224218
Summary: Kernel panic in SCTP/IpV6 server mode
Product: Base System
Version: 11.1-RELEASE
Hardware: Any
OS: Any
Status: New
Severity: Affects Only Me
Priority: ---
Component: kern
Assignee: freebsd-bugs@FreeBSD.org
Reporter: hshre...@yahoo.com
If SCTP under IpV6 is used in server mode on FreeBSD and a client connects
in[from an external device - I used linux/Ubuntu), there is a kernel panic and
of course reboot of the FreeBSD host.
Steps to reproduce:
On FreeBSD host: ncat --sctp -l <IpV6 Address of localhost> <port #>
On external machine such as Ubuntu: ncat --sctp <IpV6 address of FreeBSD host>
<port # of listener on FreeBSD above>
Instantly there is a panic on the FreeBSD host.
Running the same in IpV4 mode or reversing the flow i.e. FreeBSD client to
Linux server runs fine.
This does not seem to be the ICMPV6 issue that recently showed up. Also, I have
applied all patches via "freebsd-update fetch".
