2005-08-29[DCCP]: Fix the timestamp optionsIan McDonald
This changes timestamp, timestamp echo, and elapsed time to use units of 10 usecs as per DCCP spec. This has been tested to verify that times are correct. Also fixed up length and used hton/ntoh more. Still to add in later patches: - actually use elapsed time to adjust RTT (commented out as was prior to this patch) - send options at times more closely following the spec (content is now correct) Signed-off-by: Ian McDonald <iam4@cs.waikato.ac.nz> Signed-off-by: Arnaldo Carvalho de Melo <acme@mandriva.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2005-08-29[NET]: Implement SKB fast cloning.David S. Miller
Protocols that make extensive use of SKB cloning, for example TCP, eat at least 2 allocations per packet sent as a result. To cut the kmalloc() count in half, we implement a pre-allocation scheme wherein we allocate 2 sk_buff objects in advance, then use a simple reference count to free up the memory at the correct time. Based upon an initial patch by Thomas Graf and suggestions from Herbert Xu. Signed-off-by: David S. Miller <davem@davemloft.net>

2005-08-29[NETLINK]: Use group numbers instead of bitmasks internallyPatrick McHardy
Using the group number allows increasing the number of groups without beeing limited by the size of the bitmask. It introduces one limitation for netlink users: messages can't be broadcasted to multiple groups anymore, however this feature was never used inside the kernel.

2005-08-29[NETFILTER]: Add new iptables "connbytes" matchHarald Welte
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. Miller <davem@davemloft.net>
2005-08-29[NETFILTER]: introduce and use aligned_u64 data typeHarald Welte
As proposed by Andi Kleen, this is required esp. for x86_64 architecture, where 64bit code needs 8byte aligned 64bit data types, but 32bit userspace apps will only align to 4bytes. Signed-off-by: Harald Welte <laforge@netfilter.org> Signed-off-by: David S. Miller <davem@davemloft.net>
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[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[TCPDIAG]: Introduce inet_diag_{register,unregister}Arnaldo Carvalho de Melo
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. Signed-off-by: Arnaldo Carvalho de Melo <acme@mandriva.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2005-08-29[INET6_HASHTABLES]: Move inet6_lookup functions to net/ipv6/inet6_hashtables.cArnaldo Carvalho de Melo
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.

2005-08-29[CCID3]: Separate most of the packet history codeArnaldo Carvalho de Melo
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>
2005-08-29[TCPDIAG]: Implement cheapest way of supporting DCCPDIAG_GETSOCKArnaldo Carvalho de Melo
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.

2005-08-29[ICSK]: Move TCP congestion avoidance members to icskArnaldo Carvalho de Melo
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.

2005-08-29[TIMEWAIT]: Introduce inet_timewait_death_rowArnaldo Carvalho de Melo
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.

2005-08-29[DCCP]: make <linux/dccp.h> include-able from userspaceHarald Welte
The protocol header files in <linux/foo.h> are usually structured in a way to be included by userspace code. The top section consists of general protocol structure definitions, typedefs, enums - followed by an #ifdef __KERNEL__ section. Currently <linux/dccp.h> doesn't follow that convention and can therefore not be used from userspace. However, for example iptables' libipt_dccp.c actually needs various definitions from there.

2005-08-29[NETFILTER]: add /proc/net/netfilter interface to nf_queueHarald Welte
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). Signed-off-by: Harald Welte <laforge@netfilter.org> Signed-off-by: David S.

2005-08-29[NETFILTER]: add correct bridging support to nfnetlink_{queue,log}Harald Welte
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.
