If you take Linus's current BK tree, and apply the patch below, you
can begin trying to use the racoon and other KAME tools that we
'ported' at:
ftp://ftp.inr.ac.ru/ip-routing/ipsec/
I'll be sending this set of changes to him tonight.
Have fun :-)
ChangeSet@1.925.5.1, 2002-11-06 17:20:44-08:00, kuznet@ms2.inr.ac.ru
[IPSEC]: Semantic fixes with help from Maxim Giryaev.
- BSD apps want sin_zero cleared in sys_getname.
- Fix protocol setting in flow descriptor of RAW sockets
- Wildcard protocol is represented differently in policy
than for association.
- Missing update of key manager sequence in xfrm_state entries.
