e3e7e1673f Fix the NEXT_IA_WITH_SAME_ADDR macro introduced in 1.27: it was finding 
the first in_ifaddr structure with a different internet address!  Reverse
the sense of the test.  Spotted by and fix from Eric Haszlakiewicz.

3a9ed00799 Document that we are more conservative after doing MTU discovery than the 
suggestion in draft-floyd-incr-init-win-03.  Rather than scaling cwnd back
by the ratio of new segment size to old segment size, we perform a slow start
using the Initial Window, computed with the new segment size.

deac3540de Put original hash function back. It wastes a little bit of space, but is much more even -- think of the case of a web service provider, some of whose customers end up getting 'inferior service' because they're on addresses that happen to be out at the end of a hash chain. With webservers with thousands of addresses, this is a real issue. If the wasted space is a big deal, we could pick a prime number that's slightly _less_ than a power of two... 1998-07-16 06:45:09 +00:00

3a64270ca6 Back out the change from TCP/IP vol 2, in revision 1.7, which removed TH_FIN 
from the output flags for CLOSING state.  There is no harm in retransmitting
the FIN, and this change has unexpected side effects that break simultaneous
close behaviour.

d8b8a41918 The rewrite of if_arp.c to work with the hashed interface address lists 
(1.44) missed a test for the right interface, making some machines answer
to some bogus arp requests (like for WHO-HAS 127.0.0.1).

The quick patch in 1.46-1.47 does not work for so-called "unnumbered"
interfaces, that is, (point-to-point) interfaces that share their local
address with another (e.g., the Ethernet) interface.

We add a macro to in_var.h, to step (in the current implementation) through
the hash chain and fine more entries with the same address, and use that
in if_arp.c to find one which belongs to our interface.

651b44e211 Rework the way kernel include files are installed. In the new method, 
as with user-land programs, include files are installed by each directory
in the tree that has includes to install.  (This allows more flexibility
as to what gets installed, makes 'partial installs' easier, and gives us
more options as to which machines' includes get installed at any given
time.)  The old SYS_INCLUDES={symlinks,copies} behaviours are _both_
still supported, though at least one bug in the 'symlinks' case is
fixed by this change.  Include files can't be build before installation,
so directories that have includes as targets (e.g. dev/pci) have to move
those targets into a different Makefile.

edc01ec330 In addition to the IP flow hash table, put the flows on a list. The table 
is used for fast lookup, the list for traversal of all flows.  Also, use

837a8317b5 Eek, we were wasting almost half of the in_ifaddr hash space by modulo'ing 
with IN_IFADDR_HASH_SIZE.  Instead, AND with the hash mask computed by
hashinit().
