e794123006 Fix a rather severe bug in handling of incoming SYNs for peer/port values 
which happen to have a TCB in TIME_WAIT, where an mbuf which had been
advanced past the IP+TCP headers and TCP options would be reused as if
it had not been advanced.  Problem found by Juergen Hannken-Illjes, who
also suggested a work-around on which this fix is based.

e0acb98b94 Fix an old and obscure TCP bug, brought to my attention by Bill Fenner, 
fixed in FreeBSD by John Polstra:

Fix a bug (apparently very old) that can cause a TCP connection to
be dropped when it has an unusual traffic pattern.  For full details
as well as a test case that demonstrates the failure, see the
referenced PR (FreeBSD's kern/3998).

   Under certain circumstances involving the persist state, it is
   possible for the receive side's tp->rcv_nxt to advance beyond its
   tp->rcv_adv.  This causes (tp->rcv_adv - tp->rcv_nxt) to become
   negative.  However, in the code affected by this fix, that difference
   was interpreted as an unsigned number by max().  Since it was
   negative, it was taken as a huge unsigned number.  The effect was
   to cause the receiver to believe that its receive window had negative
   size, thereby rejecting all received segments including ACKs.  As
   the test case shows, this led to fruitless retransmissions and
   eventually to a dropped connection.  Even connections using the
   loopback interface could be dropped.  The fix substitutes the signed
   imax() for the unsigned max() function.

Bill informs me that his research indicates this bug appeared in Reno.

7845ea0d16 Fix an ... interesting bug that resulted from namespace collision. 
Description:

	- A BSD pseudo-device initialization routine is declared as
		void <pseudo-device name>attach __P((int count));
	  in ioconf.c by config(8).  main() calls these functions
	  from a table.

	- IP Filter has functions iplattach() and ipldetach() (or,
	  in the NetBSD case, were erroneously renamed ipfilterattach()
	  and ipfilterdetach()).  These functions are used to establish
	  and disestablish the IP Filter "filter rule check" hook in
	  the IP input/output stream.  They are declared:
		int iplattach __P((void));
		int ipldetach __P((void));
	  ..and are expected to return a value by iplioctl().

	- When main() calls (by sheer coincidence!) iplattach(),
	  the filter hook is established, and the IP Filter machinery
	  labeled as "initialized".  This causes all packets, whether or
	  not the user intents to use filter rules, to be passed to
	  the filter rule checker if "ipfilter" is configured into the
	  kernel.

	- As a result of the above, a kludge existed to default to
	  passing all packets (I can only assume that when this was
	  originally committed, the symptom of the bug was noticed by
	  the integrator, but the bug not actually found/fixed).

	- In iplioctl(), if the SIOCFRENB ioctl is issued with an
	  argument of "enable" (i.e. user executed "ipf -E"), iplattach()
	  will notice that the machinery is already initialized and
	  return EBUSY.

Fix:

	- Rename iplattach()/ipldetach() to ipl_enable() and ipl_disable().

	- Create a pseudo-device entry stub named ipfilterattach()
	  (NetBSD case) or iplattach() (all other).  This is a noop; none
	  of the machinery should be initialized until the caller expicitly
	  enables the filter with ipf -E.  Add a comment to note that.

I noticed a few semi-serious bugs while doing this merge, one of which
has existed for a fairly long time.  Some of them are addressed in this
commit (because they caused the kernel to not compile), and are annoted

a future commit, and, as far as I can tell, affects all operating systems
which IP Filter supports.

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

structure which included pointers, and which therefore didn't overlay

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

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.

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.
