>Description:
When using MAC with lomac security policy and MAC_DEBUG
mac_lomac_load=YES
security.mac.lomac.trust_all_interfaces=1

system panics some time after connecting to internet via user level ppp and
modem. This do not happens every time, but quite offten. I can reproduce it
without major problems. I have never observed this thing in normal (not using
modem connection to internet) use. 

Panic message is:
mac_lomac_dominate_event a->mle_type invalid

Crash dump was never successfully created. System hangs while trying
to do that.

 If you run with DDB compiled into the kernel and a serial console, is it
 possible to capture a stack trace using the "trace" command?
 
 Are you using user-space ppp using the ppp(8) command?  In particular, is
 it safe to assume you're using the tunnel device (if_tun)?

 still not fixed in 5.3-STABLE Feb 9 2005. It can be reproduced nicely
 at any time.
 loader.conf:
 mac_lomac_load=YES
 security.mac.lomac.trust_all_interfaces=1
 
 then start user mode ppp on modem line, panic will follow in 2-5 minutes later.
