Hi tech@, I've been using iked for some weeks to tunnel my laptop to home over 3G. Sunday I upgraded my laptop to the latest snapshot; previous upgrade was about 2 or 3 weeks ago. When I started iked, it crashed randomly, as in one time it runs just fine and completes the handshake, the other it crashes before even sending the first packet.
I ran "ktrace -di /sbin/iked" and kdump'd the resulting file. Of the 5
processes, 4 finished by calling exit(0), one was terminated on a
SIGSEGV. As it is also the only one that do stuff on /var/run/iked.sock,
it is the control process. I repeated the above ktrace 4 times and got
consistent results: SIGSEGV'd control process.
I'll keep the hunt going, but I am not sure how long this will take nor
how much time I'll have to spare, so here is the control process kdump.
Cheers,
--
Vincent
