Yes. :) It runs on an intranet, but there's a need to encrypt traffic.

Can you do the following (in this order) in kgdb: frame 7 p saidx p *saidx (kgdb) frame 7 #7 0xffffffff809bf779 in ipsec_process_done (m=0xfffffe000c7c7a00, isr=0xfffffe001bf54380) at /data/usr/src/sys/netipsec/ipsec_output.c:170 170 switch (saidx->dst.sa.sa_family) { (kgdb) p saidx No symbol "saidx" in current context. The latest will probably generate an error, as (if you have the exact same ipsec_output.c as I have from HEAD) saidx will probably have an invalid adress. I have the same as in HEAD. [...] 8-STABLE runs fine with the same config. Strange.... I'll review changes in IPsec stack which have been done in STABLE/9 and not backported to STABLE/8..... Oh, sorry, not quite an up-to-date 8-STABLE, it's from Sat May 21 22:05:26 CEST 2011 (csup'd some hours earlier). Should I check with a more recent version? Does that help? Thanks for helping.
