mrg 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.

cjs 788bcc9857 Fix bug in sysctl net.inet.ip.forwsrcrt handing: now you can read it
if securelevel > 0. (Thanks, cgd.)

mrg 4c8bfe2630 pseudo-device ipfilter brings in PFIL_HOOKS. 1997-02-18 20:49:32 +00:00
thorpej 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.

mrg 04ce281a19 in pfil_hooks: always reassign ip after calling hook. 1996-12-20 09:08:14 +00:00

thorpej e55c8a9c7e Before concatenating frags, sanity check the length of the packet. If it's
larger than IP_MAXPACKET, discard it.

perry 17fcad6b2c commit fix in pr 2772 -- the IP input code was assuming that the
reserved (must be zero) flag must necessarily be zero. We now define
an IP_RF (by analogy to IP_DF and IP_MF) and mask it out when necessary.

mrg a5f00f16bc move the packet filter hooks in to a saner location. while i'm here, rename
PACKET_FILTER to PFIL_HOOKS.

mycroft 62a6cce9ca Add in_nullhost() and in_hosteq() macros, to hide some protocol

mycroft f5c7d8bcc1 Save 68 bytes of the packet for ICMP, not 64. From Laine Stump, PR 2296. 1996-09-08 15:49:43 +00:00
mrg ae47956db0 add packet filter interface code. see pfil(9) for more details. you
need the PACKET_FILTER option to enable this code.  currently, ipfilter
version 3.1.1-beta has been converted to use this new interface.

thorpej 3ca11aa1ad Fix some DIAGNOSTIC printf() formats; ntohl() provides a 32-bit quantity,
and should be printed with %x, not %lx.
1996-08-14 03:46:44 +00:00
cgd 9764a289cd print result of ntohl/htonl as a long. (makes -Wformat work on the
Alpha.)

thorpej 535abd80a2 Add a net.inet.ip.directed-broadcast sysctl as suggested by
Darren Reed <darrenr@vitruvius.arbld.unimelb.edu.au> in PR #1227.
This change is slightly different than the one submitted by Darren in
that the DIRECTED_BROADCAST compile-time option will behave like it used
to so that existing configurations utilizing it won't have to change.
1996-01-16 04:17:30 +00:00
thorpej 4b359df8c4 Add net.inet.ip.forwsrcrt: if zero, the system will not forward
source-routed packets.  Note this value is protected by kernel security
level; it can only be changed if securelevel < 1.
1996-01-15 21:11:46 +00:00
cgd dfad729a16 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.

mycroft 6897f39ae9 Various cleanup, including:
* Convert several data structures to use queue.h.
* Split in_pcbnotify() into two parts; one for notifying a specific PCB, and
one for notifying all PCBs for a particular foreign address.
