c74236bfc9 Tweaks to allow operation with an interface address of 0.0.0.0
(needed for NFS mountroot using BOOTP to get boot parameters)

a0e791807e Eliminate use of dtom() from the network code, allowing more flexible
use of mbuf external storage and increasing performance (by eliminating
an m_pullup() for clusters in the IP reassembly code).

Changes from Koji Imada <koji@math.human.nagoya-u.ac.jp>, in PR #3628
and #3480, with ever-so-slight integration changes by me.

0659cacda6 Move the mtod calls *after* we've made sure that the packet has passed the
filter successfully. Otherwise it can be NULL if the filter blocked it,
and we die. How did this ever work?

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.

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

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.

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

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.

ae47956db0 add packet filter interface code. see pfil(9) for more details. you

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.

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.

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.
