[TCP]: Move sack_ok access to obviously named funcs & cleanup

2007-10-10T23:48:00+00:00

Previously code had IsReno/IsFack defined as macros that were
local to tcp_input.c though sack_ok field has user elsewhere too
for the same purpose. This changes them to static inlines as
preferred according the current coding style and unifies the
access to sack_ok across multiple files. Magic bitops of sack_ok
for FACK and DSACK are also abstracted to functions with
appropriate names.

Note:
- One sack_ok = 1 remains but that's self explanary, i.e., it
  enables sack
- Couple of !IsReno cases are changed to tcp_is_sack
- There were no users for IsDSack => I dropped it

[TCP]: Use LIMIT_NETDEBUG in tcp_retransmit_timer().

2007-06-07T20:40:08+00:00

LIMIT_NETDEBUG allows the admin to disable some warning messages (echo 0
 >/proc/sys/net/core/warnings).

The "TCP: Treason uncloaked!" message can use this facility.

[TCP]: Consolidate checking for tcp orphan count being too big.

2007-05-31T08:23:34+00:00

tcp_out_of_resources() and tcp_close() perform the
same checking of number of orphan sockets. Move this
code into common place.

[TCP]: Abstract out all write queue operations.

2007-04-26T05:24:02+00:00

This allows the write queue implementation to be changed,
for example, to one which allows fast interval searching.

[NET/IPV4/IPV6]: Change some sysctl variables to __read_mostly

2006-09-22T21:55:03+00:00

Change net/core, ipv4 and ipv6 sysctl variables to __read_mostly.

Couldn't actually measure any performance increase while testing (.3%
I consider noise), but seems like the right thing to do.

[ICSK]: Move TCP congestion avoidance members to icsk

2005-08-29T22:56:18+00:00

This changeset basically moves tcp_sk()->{ca_ops,ca_state,etc} to inet_csk(),
minimal renaming/moving done in this changeset to ease review.

Most of it is just changes of struct tcp_sock * to struct sock * parameters.

With this we move to a state closer to two interesting goals:

1. Generalisation of net/ipv4/tcp_diag.c, becoming inet_diag.c, being used
   for any INET transport protocol that has struct inet_hashinfo and are
   derived from struct inet_connection_sock. Keeps the userspace API, that will
   just not display DCCP sockets, while newer versions of tools can support
   DCCP.

2. INET generic transport pluggable Congestion Avoidance infrastructure, using
   the current TCP CA infrastructure with DCCP.
