The issue is a check which is causing a oops/crash when a send buffer is referenced more than once when calling pskb_expand_head(). As mentioned in comment #18, this seems to be introduced by a series of patches modifying the way fragments are handled.
The networking code is quite complex, so I am not sure whether some detail I found actually is causing this issues (one backport claims to drop some extraneous initialization in ipv6 which was not done in the ipv4 counterpart), but I created a test kernel to see what happens. If someone could give http://people.canonical.com/~smb/lp1824687/ a try and let me know I would highly appreciate. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1824687 Title: 4.4.0-145-generic Kernel Panic ip6_expire_frag_queue To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1824687/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
