* [NET]: Do not protect sysctl_optmem_max with CONFIG_SYSCTLDavid S. Miller2005-09-051-1/+2

* [IRDA]: IrDA prototype fixesAdrian Bunk2005-09-051-1/+1
| | | | | | | | | | | Every file should #include the header files containing the prototypes of it's global functions.

| * [TCP]: Fix sk_forward_alloc underflow in tcp_sendmsgHerbert Xu2005-09-011-3/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I've finally found a potential cause of the sk_forward_alloc underflows that people have been reporting sporadically. When tcp_sendmsg tacks on extra bits to an existing TCP_PAGE we don't check sk_forward_alloc even though a large amount of time may have elapsed since we allocated the page. In the mean time someone could've come along and liberated packets and reclaimed sk_forward_alloc memory. This patch makes tcp_sendmsg check sk_forward_alloc every time as we do in do_tcp_sendpages.

| * [NET]: Implement SKB fast cloning.David S. Miller2005-08-291-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

| * [INET_DIAG]: Move the tcp_diag interface to the proper placeArnaldo Carvalho de Melo2005-08-291-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| * [INET6_HASHTABLES]: Move inet6_lookup functions to net/ipv6/inet6_hashtables.cArnaldo Carvalho de Melo2005-08-291-1/+105
| | | | | | | | | | | | | | | | | | | | | | | | 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.

| * [ICSK]: Move TCP congestion avoidance members to icskArnaldo Carvalho de Melo2005-08-292-32/+57
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

One thing I'll investigate at some point is to have the inet_hashinfo pointer in sk_prot, so that we get all the hashtable information from the sk pointer, this can lead to some extra indirections that may well hurt performance/code size, we'll see. Ultimate idea would be that sk_prot would provide _all_ the information about a protocol implementation. Signed-off-by: Arnaldo Carvalho de Melo <acme@ghostprotocols.net> Signed-off-by: David S.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This should really be in a inet_connection_sock, but I'm leaving it for a later optimization, when some more fields common to INET transport protocols now in tcp_sk or inet_sk will be chunked out into inet_connection_sock, for now its better to concentrate on getting the changes in the core merged to leave the DCCP tree with only DCCP specific code. Next changesets will take advantage of this move to generalise things like tcp_bind_hash, tcp_put_port, tcp_inherit_port, making the later receive a inet_hashinfo parameter, and even __tcp_tw_hashdance, etc in the future, when tcp_tw_bucket gets transformed into the struct timewait_sock hierarchy. tcp_destroy_sock also is eligible as soon as tcp_orphan_count gets moved to sk_prot.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is to break down the complexity of the series of patches, making it very clear that this one just does: 1. renames tcp_ prefixed hashtable functions and data structures that were already mostly generic to inet_ to share it with DCCP and other INET transport protocols. 2. Removes not used functions (__tb_head & tb_head) 3. Removes some leftover prototypes in the headers (tcp_bucket_unlock & tcp_v4_build_header) Next changesets will move tcp_sk(sk)->bind_hash to inet_sock so that we can make functions such as tcp_inherit_port, __tcp_inherit_port, tcp_v4_get_port, __tcp_put_port, generic and get others like tcp_destroy_sock closer to generic (tcp_orphan_count will go to sk->sk_prot to allow this).

| * [INET]: Move the TCP ehash functions to include/net/inet_hashtables.hArnaldo Carvalho de Melo2005-08-291-0/+40
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | To be shared with DCCP (and others), this is the start of a series of patches that will expose the already generic TCP hash table routines. The few changes noticed when calling gcc -S before/after on a pentium4 were of this type: movl 40(%esp), %edx cmpl %esi, 472(%edx) je .L168 - pushl $291 + pushl $272 pushl $.LC0 pushl $.LC1 pushl $.LC2 [acme@toy net-2.6.14]$ size net/ipv4/tcp_ipv4.before.o net/ipv4/tcp_ipv4.after.o text data bss dec hex filename 17804 516 140 18460 481c net/ipv4/tcp_ipv4.before.o 17804 516 140 18460 481c net/ipv4/tcp_ipv4.after.o Holler if some weird architecture has issues with things like this 8) Signed-off-by: Arnaldo Carvalho de Melo <acme@ghostprotocols.net> Signed-off-by: David S.

| * [INET]: Introduce inet_sk_rebuild_headerArnaldo Carvalho de Melo2005-08-291-2/+0
| | | | | | | | | | | | | | | | | | | | From tcp_v4_rebuild_header, that already was pretty generic, I only needed to use sk->sk_protocol instead of the hardcoded IPPROTO_TCP and establish the requirement that INET transport layer protocols that want to use this function map TCP_SYN_SENT to its equivalent state.

| * [SOCK]: Introduce sk_setup_capsArnaldo Carvalho de Melo2005-08-292-9/+10
| | | | | | | | | | | | | | | | | | From tcp_v4_setup_caps, that always is preceded by a call to __sk_dst_set, so coalesce this sequence into sk_setup_caps, removing one call to a TCP function in the IP layer.
