* [IPSEC]: Document that policy direction is derived from the index.Herbert Xu2005-10-05
| | | | | | | | | | | Here is a patch that adds a helper called xfrm_policy_id2dir to document the fact that the policy direction can be and is derived from the index.

* [INET]: speedup inet (tcp/dccp) lookupsEric Dumazet2005-10-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Arnaldo and I agreed it could be applied now, because I have other pending patches depending on this one (Thank you Arnaldo) (The other important patch moves skc_refcnt in a separate cache line, so that the SMP/NUMA performance doesnt suffer from cache line ping pongs) 1) First some performance data : -------------------------------- tcp_v4_rcv() wastes a *lot* of time in __inet_lookup_established() The most time critical code is : sk_for_each(sk, node, &head->chain) { if (INET_MATCH(sk, acookie, saddr, daddr, ports, dif)) goto hit; /* You sunk my battleship! */ } The sk_for_each() does use prefetch() hints but only the begining of "struct sock" is prefetched. As INET_MATCH first comparison uses inet_sk(__sk)->daddr, wich is far away from the begining of "struct sock", it has to bring into CPU cache cold cache line. Each iteration has to use at least 2 cache lines. This can be problematic if some chains are very long. 2) The goal ----------- The idea I had is to change things so that INET_MATCH() may return FALSE in 99% of cases only using the data already in the CPU cache, using one cache line per iteration. 3) Description of the patch --------------------------- Adds a new 'unsigned int skc_hash' field in 'struct sock_common', filling a 32 bits hole on 64 bits platform. struct sock_common { unsigned short skc_family; volatile unsigned char skc_state; unsigned char skc_reuse; int skc_bound_dev_if; struct hlist_node skc_node; struct hlist_node skc_bind_node; atomic_t skc_refcnt; + unsigned int skc_hash; struct proto *skc_prot; }; Store in this 32 bits field the full hash, not masked by (ehash_size - 1) Using this full hash as the first comparison done in INET_MATCH permits us immediatly skip the element without touching a second cache line in case of a miss. Suppress the sk_hashent/tw_hashent fields since skc_hash (aliased to sk_hash and tw_hash) already contains the slot number if we mask with (ehash_size - 1) File include/net/inet_hashtables.h 64 bits platforms : #define INET_MATCH(__sk, __hash, __cookie, __saddr, __daddr, __ports, __dif)\ (((__sk)->sk_hash == (__hash)) ((*((__u64 *)&(inet_sk(__sk)->daddr)))== (__cookie)) && \ ((*((__u32 *)&(inet_sk(__sk)->dport))) == (__ports)) && \ (!((__sk)->sk_bound_dev_if) || ((__sk)->sk_bound_dev_if == (__dif)))) 32bits platforms: #define TCP_IPV4_MATCH(__sk, __hash, __cookie, __saddr, __daddr, __ports, __dif)\ (((__sk)->sk_hash == (__hash)) && \ (inet_sk(__sk)->daddr == (__saddr)) && \ (inet_sk(__sk)->rcv_saddr == (__daddr)) && \ (!((__sk)->sk_bound_dev_if) || ((__sk)->sk_bound_dev_if == (__dif)))) - Adds a prefetch(head->chain.first) in __inet_lookup_established()/__tcp_v4_check_established() and __inet6_lookup_established()/__tcp_v6_check_established() and __dccp_v4_check_established() to bring into cache the first element of the list, before the {read|write}_lock(&head->lock); Signed-off-by: Eric Dumazet <dada1@cosmosbay.com> Acked-by: Arnaldo Carvalho de Melo <acme@ghostprotocols.net> Signed-off-by: David S.

| | | | | | | | | | | | | | So as to set the newly created sk_buff ->dev member with it, that way we stop using dev_base->next, that is the wrong thing to do, as there may well be several interfaces being used with LLC. This was not such a big problem after all as most of the users of llc_alloc_frame were setting the correct dev, but this way code is reduced.

* [IPVS]: ip_vs_ftp breaks connections using persistenceJulian Anastasov2005-09-15
| | | | | | | | | | | | | | | | | | | | | | | | ip_vs_ftp when loaded can create NAT connections with unknown client port for passive FTP. For such expectations we lookup with cport=0 on incoming packet but it matches the format of the persistence templates causing packets to other persistent virtual servers to be forwarded to real server without creating connection. Later the reply packets are treated as foreign and not SNAT-ed. This patch changes the connection lookup for packets from clients: * introduce IP_VS_CONN_F_TEMPLATE connection flag to mark the connection as template * create new connection lookup function just for templates - ip_vs_ct_in_get * make sure ip_vs_conn_in_get hits only connections with IP_VS_CONN_F_NO_CPORT flag set when s_port is 0. By this way we avoid returning template when looking for cport=0 (ftp) Signed-off-by: Julian Anastasov <ja@ssi.bg> Signed-off-by: David S. Miller <davem@davemloft.net>

* | [NETROM]: Implement G8PZT Circuit reset for NET/ROMRalf Baechle2005-09-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | NET/ROM is lacking a connection reset like TCP's RST flag which at times may result in a connecting having to slowly timing out instead of just being reset. An earlier attempt to reset the connection by sending a NR_CONNACK | NR_CHOKE_FLAG transport was inacceptable as it did result in crashes of BPQ systems. An alternative approach of introducing a new transport type 7 (NR_RESET) has be implemented several years ago in Paula Jayne Dowie G8PZT's Xrouter. Implement NR_RESET for Linux's NET/ROM but like any messing with the state engine consider this experimental for now and thus control it by a sysctl (net.netrom.reset) which for the time being defaults to off.

It was supposed to be the fallback of the WPA API changes, but people seem quite happy about it (especially Jouni), so the patch is rather small. The patch has been fully tested with 2.6.13 and various wireless drivers, and is in its final version. Would you mind pushing that into Linus's kernel so that the driver and the apps can take advantage ot it ? It includes : o iwstat improvement (explicit dBm). This is the result of long discussions with Dan Williams, the authors of NetworkManager. Thanks to him for all the fruitful feedback. o remove pointer from event stream. I was not totally sure if this pointer was 32-64 bits clean, so I'd rather remove it and be at peace with it. o remove linux header from wireless.h. This has long been requested by people writting user space apps, now it's done, and it was not even painful. o final deprecation of spy_offset. You did not like it, it's now gone for good. o Start deprecating dev->get_wireless_stats -> debloat netdev o Add "check" version of event macros for ieee802.11 stack. Jiri Benc doesn't like the current macros, we aim to please ;-) All those changes, except the last one, have been bit-roting on my web pages for a while... Patches for most kernel drivers will follow. Patches for the Orinoco and the HostAP drivers have been sent to their respective maintainers. Have fun...

Now to aim at UDP, converting it to use inet_hashinfo, so that we can use iproute2 for UDP sockets as well.

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.
