* [NETFILTER]: Add new iptables "connbytes" matchHarald Welte2005-08-29
| | | | | | | | | This patch ads a new "connbytes" match that utilizes the CONFIG_NF_CT_ACCT per-connection byte and packet counters. Using it you can do things like packet classification on average packet size within a connection. Signed-off-by: Harald Welte <laforge@netfilter.org> Signed-off-by: David S.

* [INET_DIAG]: Move the tcp_diag interface to the proper placeArnaldo Carvalho de Melo2005-08-29
| | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* [INET_DIAG]: Rename tcp_diag.[ch] to inet_diag.[ch]Arnaldo Carvalho de Melo2005-08-29
| | | | | | | | 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>
* [TCPDIAG]: Just rename everything to inet_diagArnaldo Carvalho de Melo2005-08-29
| | | | | | | | | | 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>
* [TCPDIAG]: Introduce inet_diag_{register,unregister}Arnaldo Carvalho de Melo2005-08-29
| | | | | | | | | | Next changeset will rename tcp_diag to inet_diag and move the tcp_diag code out of it and into a new tcp_diag.c, similar to the net/dccp/diag.c introduced in this changeset, completing the transition to a generic inet_diag infrastructure.

* [INET6_HASHTABLES]: Move inet6_lookup functions to net/ipv6/inet6_hashtables.cArnaldo Carvalho de Melo2005-08-29
| | | | | | | | | | | | Doing this we allow tcp_diag to support IPV6 even if tcp_diag is compiled statically and IPV6 is compiled as a module, removing the previous restriction while not building any IPV6 code if it is not selected. Now to work on the tcpdiag_register infrastructure and then to rename the whole thing to inetdiag, reflecting its by then completely generic nature.

* [NET]: Make use of ->private_data in sockfd_lookupBenjamin LaHaise2005-08-29
| | | | | | | | | Please consider the patch below which makes use of file->private_data to store the pointer to the socket, which avoids touching several unused cachelines in the dentry and inode in sockfd_lookup.

* [CCID3]: Ditch USEC_IN_SEC as time.h has USEC_PER_SECArnaldo Carvalho de Melo2005-08-29

* [CCID3]: Separate most of the packet history codeArnaldo Carvalho de Melo2005-08-29
| | | | | | | | | | This also changes the list_for_each_entry_safe_continue behaviour to match its kerneldoc comment, that is, to start after the pos passed. Also adds several helper functions from previously open coded fragments, making the code more clear. Signed-off-by: Arnaldo Carvalho de Melo <acme@mandriva.com>
* [TCPDIAG]: Implement cheapest way of supporting DCCPDIAG_GETSOCKArnaldo Carvalho de Melo2005-08-29
| | | | | | | | | | | | | | | | | | | | With ugly ifdefs, etc, but this actually: 1. keeps the existing ABI, i.e. no need to recompile the iproute2 utilities if not interested in DCCP. 2. Provides all the tcp_diag functionality in DCCP, with just a small patch that makes iproute2 support DCCP. Of course I'll get this cleaned-up in time, but for now I think its OK to be this way to quickly get this functionality. iproute2-ss050808 patch at: http://vger.kernel.org/~acme/iproute2-ss050808.dccp.patch Signed-off-by: Arnaldo Carvalho de Melo <acme@mandriva.com> Signed-off-by: David S.

* [ICSK]: Move TCP congestion avoidance members to icskArnaldo Carvalho de Melo2005-08-29
| | | | | | | | | | | | | | | | | | | | | 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.

* [DCCP]: Finish the TIMEWAIT minisock supportArnaldo Carvalho de Melo2005-08-29
| | | | | | | | | Using most of the infrastructure TCP uses, with a dccp_death_row, etc. As per my current interpretation of the draft what we have with this changeset seems to be all we need (or very close to it 8)).

* [TIMEWAIT]: Introduce inet_timewait_death_rowArnaldo Carvalho de Melo2005-08-29
| | | | | | | | | | | That groups all of the tables and variables associated to the TCP timewait schedulling/recycling/killing code, that now can be isolated from the TCP specific code and used by other transport protocols, such as DCCP. Next changeset will move this code to net/ipv4/inet_timewait_sock.c Signed-off-by: Arnaldo Carvalho de Melo <acme@mandriva.com> Signed-off-by: David S. Miller <davem@davemloft.net>
* [DCCP]: Initialize icsk_rto in dccp_v4_init_sockArnaldo Carvalho de Melo2005-08-29

* [DCCP]: Introduce dccp_write_xmit from code in dccp_sendmsgArnaldo Carvalho de Melo2005-08-29
| | | | | | | | | | This way it gets closer to the TCP flow, where congestion window checks are done, it seems we can map ccid_hc_tx_send_packet in dccp_write_xmit to tcp_snd_wnd_test in tcp_write_xmit, a CCID2 decision should just fit in here as well...

* [NETFILTER]: return ENOMEM when ip_conntrack_alloc() fails.Yasuyuki Kozakai2005-08-29
| | | | | | | | | | | | | This patch fixes the bug which doesn't return ERR_PTR(-ENOMEM) if it failed to allocate memory space from slab cache. This bug leads to erroneously not dropped packets under stress, and wrong statistic counters ('invalid' is incremented instead of 'drop'). It was introduced during the ctnetlink merge in the net-2.6.14 tree, so no stable or mainline releases affected.

* [NETFILTER]: more verbose return codes from nf_{log,queue}Harald Welte2005-08-29
| | | | | | | | | | | This adds EEXIST to distinguish between the following return values: 0: nobody was registered, registration successful EEXIST: the exact same handler was already registered, no registration required EBUSY: somebody else is registered, registration unsuccessful.

* [NETFILTER]: add /proc/net/netfilter interface to nf_queueHarald Welte2005-08-29
| | | | | | | | | | | This patch adds a /proc/net/netfilter/nf_queue file, similar to the recently-added /proc/net/netfilter/nf_log. It indicates which queue handler is registered to which protocol family. This is useful since there are now multiple queue handlers in the treee (ip[6]_queue, nfnetlink_queue).

* [NETFILTER]: add correct bridging support to nfnetlink_{queue,log}Harald Welte2005-08-29
| | | | | | | | | | | | This patch adds support for passing the real 'physical' device ifindex down to userspace via nfnetlink_log and nfnetlink_queue. This feature basically obsoletes net/bridge/netfilter/ebt_ulog.c, and it is likely ebt_ulog.c will die with one of the next couple of patches.

* [NETFILTER]: split net/core/netfilter.c into net/netfilter/*.cHarald Welte2005-08-29
| | | | | | | | | | This patch doesn't introduce any code changes, but merely splits the core netfilter code into four separate files. It also moves it from it's old location in net/core/ to the recently-created net/netfilter/ directory. Signed-off-by: Harald Welte <laforge@netfilter.org> Signed-off-by: David S. Miller <davem@davemloft.net>
* [NETFILTER]: ip{6}_queue: prevent unregistration race with nfnetlink_queueHarald Welte2005-08-29
| | | | | | | | | Since nfnetlink_queue can override ip{6}_queue as queue handlers, we can no longer blindly unregister whoever is registered for PF_INET[6], but only unregister ourselves. Signed-off-by: Harald Welte <laforge@netfilter.org> Signed-off-by: David S. Miller <davem@davemloft.net>

* [NETFILTER]: move conntrack helper buffers from BSS to kmalloc()ed memoryHarald Welte2005-08-29
| | | | | | | | | | | | According to DaveM, it is preferrable to have large data structures be allocated dynamically from the module init() function rather than putting them as static global variables into BSS.
