* | [TCP]: speed up SACK processingStephen Hemminger2005-11-102-26/+172
| | | | | | | | | | | | | | | | | | Use "hints" to speed up the SACK processing. Various forms of this have been used by TCP developers (Web100, STCP, BIC) to avoid the 2x linear search of outstanding segments.

* | [TCP]: receive buffer growth limiting with mixed MTUJohn Heffner2005-11-101-27/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is a patch for discussion addressing some receive buffer growing issues. This is partially related to the thread "Possible BUG in IPv4 TCP window handling..." last week. Specifically it addresses the problem of an interaction between rcvbuf moderation (receiver autotuning) and rcv_ssthresh. The problem occurs when sending small packets to a receiver with a larger MTU. (A very common case I have is a host with a 1500 byte MTU sending to a host with a 9k MTU.) In such a case, the rcv_ssthresh code is targeting a window size corresponding to filling up the current rcvbuf, not taking into account that the new rcvbuf moderation may increase the rcvbuf size. One hunk makes rcv_ssthresh use tcp_rmem[2] as the size target rather than rcvbuf. The other changes the behavior when it overflows its memory bounds with in-order data so that it tries to grow rcvbuf (the same as with out-of-order data). These changes should help my problem of mixed MTUs, and should also help the case from last week's thread I think. (In both cases though you still need tcp_rmem[2] to be set much larger than the TCP window.) One question is if this is too aggressive at trying to increase rcvbuf if it's under memory stress.

* | [TCP]: Appropriate Byte Count supportStephen Hemminger2005-11-105-11/+37
| | | | | | | | | | | | | | | | | | | | | | | | | | This is an updated version of the RFC3465 ABC patch originally for Linux 2.6.11-rc4 by Yee-Ting Li. ABC is a way of counting bytes ack'd rather than packets when updating congestion control. The orignal ABC described in the RFC applied to a Reno style algorithm.

* | [TCP]: fix congestion window update when using TSO deferalStephen Hemminger2005-11-107-9/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | TCP peformance with TSO over networks with delay is awful. On a 100Mbit link with 150ms delay, we get 4Mbits/sec with TSO and 50Mbits/sec without TSO. The problem is with TSO, we intentionally do not keep the maximum number of packets in flight to fill the window, we hold out to until we can send a MSS chunk. But, we also don't update the congestion window unless we have filled, as per RFC2861. This patch replaces the check for the congestion window being full with something smarter that accounts for TSO.

* | [NET]: Detect hardware rx checksum faults correctlyHerbert Xu2005-11-1016-131/+139
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Here is the patch that introduces the generic skb_checksum_complete which also checks for hardware RX checksum faults. If that happens, it'll call netdev_rx_csum_fault which currently prints out a stack trace with the device name. In future it can turn off RX checksum. I've converted every spot under net/ that does RX checksum checks to use skb_checksum_complete or __skb_checksum_complete with the exceptions of: * Those places where checksums are done bit by bit. These will call netdev_rx_csum_fault directly. * The following have not been completely checked/converted: ipmr ip_vs netfilter dccp This patch is based on patches and suggestions from Stephen Hemminger and David S.

| * | [NETLINK]: Generic netlink familyThomas Graf2005-11-102-1/+580
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The generic netlink family builds on top of netlink and provides simplifies access for the less demanding netlink users. It solves the problem of protocol numbers running out by introducing a so called controller taking care of id management and name resolving. Generic netlink modules register themself after filling out their id card (struct genl_family), after successful registration the modules are able to register callbacks to command numbers by filling out a struct genl_ops and calling genl_register_op(). The registered callbacks are invoked with attributes parsed making life of simple modules a lot easier. Although generic netlink modules can request static identifiers, it is recommended to use GENL_ID_GENERATE and to let the controller assign a unique identifier to the module. Userspace applications will then ask the controller and lookup the idenfier by the module name. Due to the current multicast implementation of netlink, the number of generic netlink modules is restricted to 1024 to avoid wasting memory for the per socket multiacst subscription bitmask.

| * | [NETFILTER]: Add nf_conntrack subsystem.Yasuyuki Kozakai2005-11-0933-62/+8289
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The existing connection tracking subsystem in netfilter can only handle ipv4. There were basically two choices present to add connection tracking support for ipv6. We could either duplicate all of the ipv4 connection tracking code into an ipv6 counterpart, or (the choice taken by these patches) we could design a generic layer that could handle both ipv4 and ipv6 and thus requiring only one sub-protocol (TCP, UDP, etc.) connection tracking helper module to be written. In fact nf_conntrack is capable of working with any layer 3 protocol. The existing ipv4 specific conntrack code could also not deal with the pecularities of doing connection tracking on ipv6, which is also cured here. For example, these issues include: 1) ICMPv6 handling, which is used for neighbour discovery in ipv6 thus some messages such as these should not participate in connection tracking since effectively they are like ARP messages 2) fragmentation must be handled differently in ipv6, because the simplistic "defrag, connection track and NAT, refrag" (which the existing ipv4 connection tracking does) approach simply isn't feasible in ipv6 3) ipv6 extension header parsing must occur at the correct spots before and after connection tracking decisions, and there were no provisions for this in the existing connection tracking design 4) ipv6 has no need for stateful NAT The ipv4 specific conntrack layer is kept around, until all of the ipv4 specific conntrack helpers are ported over to nf_conntrack and it is feature complete. Once that occurs, the old conntrack stuff will get placed into the feature-removal-schedule and we will fully kill it off 6 months later.

|/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | If the call to xprt_transmit() fails due to socket buffer space exhaustion, we do not need to re-encode the RPC message when we loop back through call_transmit. Re-encoding can actually end up triggering the WARN_ON() in call_decode() if we re-encode something like a read() request and auth->au_rslack has changed. It can also cause us to increment the RPCSEC_GSS sequence number beyond the limits of the allowed window.

Unfortunately some callers of lookup_hash don't actually pass this one down. For lookup_one_len() we don't have a struct nameidata to pass down, but as this function is a library function only used by filesystem code this is an acceptable limitation. All other callers should pass down the nameidata, so this patch changes the lookup_hash interface to only take a struct nameidata argument and derives the other two arguments to __lookup_hash from it. All callers already have the nameidata argument available so this is not a problem. At the same time I'd like to deprecate the lookup_hash interface as there are better exported interfaces for filesystem usage. Before it can actually be removed I need to fix up rpc_pipefs.

* | | | | [IPVS]: fix connection leak if expire_nodest_conn=1Julian Anastasov2005-11-081-4/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There was a fix in 2.6.13 that changed the behaviour of ip_vs_conn_expire_now function not to put reference to connection, its callers should hold write lock or connection refcnt. But we forgot to convert one caller, when the real server for connection is unavailable caller should put the connection reference. It happens only when sysctl var expire_nodest_conn is set to 1 and such connections never expire. Thanks to Roberto Nibali who found the problem and tested a 2.4.32-rc2 patch, which is equal to this 2.6 version. Patch for 2.4 is already sent to Marcelo.
