78cd2f6f78 allow src-routed packetd by default, per host requirements 1997-02-26 04:09:32 +00:00
cjs
8a449a258b Add net.inet.ip.allowsrcrt option which allows/drops all source 
routed packets. This currently defaults to `drop,' but once we
verify  that all applications that rely on determining remote IP
addresses for authentication are dropping the connection when they
see a source route option (not just disabling the source route
option), we can turn this back on and conform with the host
requirements.

9df1988ac8 Implement the IP_RECVIF socket option: supply a datagram packet's incoming 
interface using a sockaddr_dl in a control mbuf.

Implement SO_TIMESTAMP for IP datagrams.

Move packet information option processing into a generic function
so that they work with multicast UDP and raw IP as well as unicast UDP.

08899f4a1b Fix a mbuf leak in ip_output(). 
Scenario: If ip_insertoptions() prepends a new mbuf to the chain, the
bad: label's m_freem(m0) still would free only the original mbuf chain
if the transmission failed for, e.g., no route to host; resulting in
one lost mbuf per failed packet. (The original posting included a
demonstration program).

Original report of this bug was by jinmei@isl.rdc.toshiba.co.jp
(JINMEI Tatuya) on comp.bugs.4bsd.

dfad729a16 make netinet work on systems where pointers and longs are 64 bits

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.
