* fix same-interface-out-as-in and packet gets corrupted bug noted byderaadt1999-09-231-2/+1
| | | | | | | james@oaktree.co.uk by re-working icmp embedded-packet code so that ip_forward() m_copy()-aliased packet can be forwarded to ip_output and icmp_error() safely, because no packet tweaking is needed before calling icmp_error()
* return a ICMP_UNREACH_PROTOCOL for protocols we do not support; discussion with cmetzderaadt1999-06-071-2/+6

* messup, learn to test *all* variants of compile options whenniklas1999-04-201-5/+2
| | | | altering the logic round such.
* Merge MROUTING and IPSEC wrt handling of IP-in-IP tunnelled packets.niklas1999-04-201-2/+5
| | | | | Fix a panic case in the MROUTING code too. Drop M_TUNNEL support, nothing ever uses it.
* netinet merge of NRL stuff. some indent and shrinkage needed; NRL/cmetzderaadt1999-01-111-2/+23

* first step to the setsockopt/getsockopt interface as described inprovos1998-05-181-2/+9
| | | | | | | draft-mcdonald-simple-ipsec-api, kernel notifies (EMT_REQUESTSA) signal userland key management applications when security services are requested. this is only for outgoing connections at the moment, incoming packets are not yet checked against the selected socket policy.

* from netbsd:deraadt1995-12-141-1/+11
| | | | | | | | | make netinet work on systems where pointers and longs are 64 bits (like the alpha). Biggest problem: IP headers were overlayed with structure which included pointers, and which therefore didn't overlay properly on 64-bit machines. Solution: instead of threading pointers through IP header overlays, add a "queue element" structure to do the threading, and point it at the ip headers.
