2005-08-29[INET_DIAG]: Move the tcp_diag interface to the proper placeArnaldo Carvalho de Melo
With this the previous setup is back, i.e. tcp_diag can be built as a module, as dccp_diag and both share the infrastructure available in inet_diag. If one selects CONFIG_INET_DIAG as module CONFIG_INET_TCP_DIAG will also be built as a module, as will CONFIG_INET_DCCP_DIAG, if CONFIG_IP_DCCP was selected static or as a module, if CONFIG_INET_DIAG is y, being statically linked CONFIG_INET_TCP_DIAG will follow suit and CONFIG_INET_DCCP_DIAG will be built in the same manner as CONFIG_IP_DCCP. Now to aim at UDP, converting it to use inet_hashinfo, so that we can use iproute2 for UDP sockets as well. Ah, just to show an example of this new infrastructure working for DCCP :-) [root@qemu ~]# ./ss -dane State Recv-Q Send-Q Local Address:Port Peer Address:Port LISTEN 0 0 *:5001 *:* ino:942 sk:cfd503a0 ESTAB 0 0 127.0.0.1:5001 127.0.0.1:32770 ino:943 sk:cfd50a60 ESTAB 0 0 127.0.0.1:32770 127.0.0.1:5001 ino:947 sk:cfd50700 TIME-WAIT 0 0 127.0.0.1:32769 127.0.0.1:5001 timer:(timewait,3.430ms,0) ino:0 sk:cf209620 Signed-off-by: Arnaldo Carvalho de Melo <acme@mandriva.com> Signed-off-by: David S.

2005-08-29[INET_DIAG]: Rename tcp_diag.[ch] to inet_diag.[ch]Arnaldo Carvalho de Melo
Next changeset will introduce net/ipv4/tcp_diag.c, moving the code that was put transitioanlly in inet_diag.c. Signed-off-by: Arnaldo Carvalho de Melo <acme@mandriva.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2005-08-29[TCPDIAG]: Just rename everything to inet_diagArnaldo Carvalho de Melo
Next changeset will rename tcp_diag.[ch] to inet_diag.[ch]. I'm taking this longer route so as to easy review, making clear the changes made all along the way. Signed-off-by: Arnaldo Carvalho de Melo <acme@mandriva.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2005-08-29[NET]: Just move the inet_connection_sock function from tcp sourcesArnaldo Carvalho de Melo
Completing the previous changeset, this also generalises tcp_v4_synq_add, renaming it to inet_csk_reqsk_queue_hash_add, already geing used in the DCCP tree, which I plan to merge RSN.

2005-08-29[INET]: Generalise the TCP sock ID lookup routinesArnaldo Carvalho de Melo
And also some TIME_WAIT functions. [acme@toy net-2.6.14]$ grep built-in /tmp/before.size /tmp/after.size /tmp/before.size: 282955 13122 9312 305389 4a8ed net/ipv4/built-in.o /tmp/after.size: 281566 13122 9312 304000 4a380 net/ipv4/built-in.o [acme@toy net-2.6.14]$ I kept them still inlined, will uninline at some point to see what would be the performance difference.

2005-08-29[NETFILTER]: Move ipv4 specific code from net/core/netfilter.c to ↵Harald Welte
net/ipv4/netfilter.c Netfilter cleanup - Move ipv4 code from net/core/netfilter.c to net/ipv4/netfilter.c - Move ipv6 netfilter code from net/ipv6/ip6_output.c to net/ipv6/netfilter.c Signed-off-by: Harald Welte <laforge@netfilter.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2005-07-27[NET]: Move in_aton from net/ipv4/utils.c to net/core/utils.cMatt Mackall
Move in_aton to allow netpoll and pktgen to work without the rest of the IPv4 stack. Fix whitespace and add comment for the odd placement.

2005-06-23[TCP]: Add Scalable TCP congestion control module.John Heffner
This patch implements Tom Kelly's Scalable TCP congestion control algorithm for the modular framework. The algorithm has some nice scaling properties, and has been used a fair bit in research, though is known to have significant fairness issues, so it's not really suitable for general purpose use.

2005-06-23[TCP]: Add H-TCP congestion control module.Baruch Even
H-TCP is a congestion control algorithm developed at the Hamilton Institute, by Douglas Leith and Robert Shorten. It is extending the standard Reno algorithm with mode switching is thus a relatively simple modification. H-TCP is defined in a layered manner as it is still a research platform. The basic form includes the modification of beta according to the ratio of maxRTT to min RTT and the alpha=2*factor*(1-beta) relation, where factor is dependant on the time since last congestion. The other layers improve convergence by adding appropriate factors to alpha. The following patch implements the H-TCP algorithm in it's basic form.

2005-06-23[TCP]: Add TCP Hybla congestion control module.Daniele Lacamera
TCP Hybla congestion avoidance. - "In heterogeneous networks, TCP connections that incorporate a terrestrial or satellite radio link are greatly disadvantaged with respect to entirely wired connections, because of their longer round trip times (RTTs). To cope with this problem, a new TCP proposal, the TCP Hybla, is presented and discussed in the paper[1]. It stems from an analytical evaluation of the congestion window dynamics in the TCP standard versions (Tahoe, Reno, NewReno), which suggests the necessary modifications to remove the performance dependence on RTT.[...]"[1] [1]: Carlo Caini, Rosario Firrincieli, "TCP Hybla: a TCP enhancement for heterogeneous networks", International Journal of Satellite Communications and Networking Volume 22, Issue 5 , Pages 547 - 566.

2005-04-16Linux-2.6.12-rc2Linus Torvalds
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
