Are there any known problems in the 4.3 code dealing with IP options?
I can't understand it....
Specifically, in routine ip_dooptoptions, file ip_input.c:
1) Strict source route with record
appears to record an address for the receiving
interface rather than the transmitting one.
2) Record route
appears to route the datagram based on a garbage address,
bouncing an ICMP "source route failed" if this fails or
recording an address for the bogus transmitting interface
if it succeeds.
Are these bugs or have I missed something?
Has anybody fixed them?
Does anybody use IP options anyway?
Do I have an out-of-date RFC?
Thanks in antici... . . . pation,
Reference: RFC 791: IP protocol spec. Sept '81 pp. 20,21
"... address as known in the environment into which
this datagram is being forwarded"
(identical wording in two places)
