is 4555777c80 Fix several bugs related to the new ARP code, and ARCnet ARP support.
Among other, add ARPHRD_ARCNET definition, make sure the hardware type is
set on outgoing ARP packets, make sure we dont send out replies as broadcasts.

cgd a8bb00476f ioctl commands are u_longs 1997-03-18 07:14:45 +00:00

is 07b064e02e New ARP system, supports IPv4 over any hardware link.
Some of the stuff (e.g., rarpd, bootpd, dhcpd etc., libsa) still will
only support Ethernet. Tcpdump itself should be ok, but libpcap needs
lot of work.

For the detailed change history, look at the commit log entries for
the is-newarp branch.

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.

so that they work with multicast UDP and raw IP as well as unicast UDP.

is 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.

through IP header overlays, add a "queue element" structure to do
the threading, and point it at the ip headers.

mycroft 87b39add50 As I described this on comp.protocols.tcp-ip:
I've found a problem with the TCP delayed ack algorithm.  If the writer's
buffer becomes full before sending an entire window, the writer will stop
and the ack will be delayed and the transmission will be stalled pending
a timeout on (and transmission of) the delayed ack.

As an experiment, I've applied the following patch to my (NetBSD) kernel,
and it alleviates the problem.

The worst case for this change is that the writer sets the PSH bit on
every outgoing packet, in which case delayed ack is effectively disabled.
This is not an issue of correctness, however, and since most vendors use
the PSH bit a bit more intelligently, it doesn't seem like a serious
problem.

cgd ec3f94cfcd fix from david greenman, davidg@freefall.cdrom.com:
fixed bug where large amounts of unidirectional UDP traffic would fill
the interface output queue and further udp packets would be fragmented
and only partially sent - keeping the output queue full and jamming the
network, but not actually getting any real work done (because you can't
send just 'part' of a udp packet - if you fragment it, you must send
the whole thing). The fix involves adding a check to make sure that the
output queue has sufficient space for all of the fragments.
