Sounds like PR 13813 and/or 15953 (personally, they look the same to
me, but those who know more than I think that they're different <shrug>)
I can reproduce this one fairly easily. I just need to use racoon and
# for clients with dynamic IPs
to the config. Then after hitting the machine from about 5 different
IPs (or from the same machine about 5 times), the machine will panic
in a call to key_delsp()
I spent some time figuring out what was going on. Here's the email
that I sent as a result:
Basically, I found that the kernel was dying inside of the LIST_REMOVE()
macro found in key_freesp(). The link list appears to have been stomped.
My best guess was that there's a missing splsoftnet()/splx() somewhere.
