2011-04-06ipv6: Enable RFS sk_rxhash tracking for ipv6 sockets (v2)Neil Horman2-1/+6
properly record sk_rxhash in ipv6 sockets (v2) Noticed while working on another project that flows to sockets which I had open on a test systems weren't getting steered properly when I had RFS enabled. Looking more closely I found that: 1) The affected sockets were all ipv6 2) They weren't getting steered because sk->sk_rxhash was never set from the incomming skbs on that socket. This was occuring because there are several points in the IPv4 tcp and udp code which save the rxhash value when a new connection is established. Those calls to sock_rps_save_rxhash were never added to the corresponding ipv6 code paths. This patch adds those calls. Tested by myself to properly enable RFS functionalty on ipv6.

2011-04-06can: mcp251x: Allow pass IRQ flags through platform data.Enric Balletbo i Serra2-1/+4
When an interrupt occurs, the INT pin is driven low by the MCP251x controller (falling edge) but in some cases the INT pin can be connected to the MPU through a transistor or level translator which inverts this signal. In this case interrupt should be configured in rising edge. This patch adds support to pass the IRQ flags via mcp251x_platform_data.

2011-04-05ethtool: Change ETHTOOL_PHYS_ID implementation to allow dropping RTNLBen Hutchings2-3/+82
The ethtool ETHTOOL_PHYS_ID command runs for an arbitrarily long period of time, holding the RTNL lock. This blocks routing updates, device enumeration, and various important operations that one might want to keep running while hunting for the flashing LED. We need to drop the RTNL lock during this operation, but currently the core implementation is a thin wrapper around a driver operation and drivers may well depend upon holding the lock. Define a new driver operation 'set_phys_id' with an argument that sets the ID indicator on/off/inactive/active (the last optional, for any driver or firmware that prefers to handle blinking asynchronously). When this is defined, the ethtool core drops the lock while waiting and only acquires it around calls to this operation. Deprecate the 'phys_id' operation in favour of this. It can be removed once all in-tree drivers are converted. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com>

2011-04-04net: Allow no-cache copy from user on transmitTom Herbert6-6/+73
This patch uses __copy_from_user_nocache on transmit to bypass data cache for a performance improvement. skb_add_data_nocache and skb_copy_to_page_nocache can be called by sendmsg functions to use this feature, initial support is in tcp_sendmsg. This functionality is configurable per device using ethtool. Presumably, this feature would only be useful when the driver does not touch the data. The feature is turned on by default if a device indicates that it does some form of checksum offload; it is off by default for devices that do no checksum offload or indicate no checksum is necessary. For the former case copy-checksum is probably done anyway, in the latter case the device is likely loopback in which case the no cache copy is probably not beneficial. This patch was tested using 200 instances of netperf TCP_RR with 1400 byte request and one byte reply. Platform is 16 core AMD x86. No-cache copy disabled: 672703 tps, 97.13% utilization 50/90/99% latency:244.31 484.205 1028.41 No-cache copy enabled: 702113 tps, 96.16% utilization, 50/90/99% latency 238.56 467.56 956.955 Using 14000 byte request and response sizes demonstrate the effects more dramatically: No-cache copy disabled: 79571 tps, 34.34 %utlization 50/90/95% latency 1584.46 2319.59 5001.76 No-cache copy enabled: 83856 tps, 34.81% utilization 50/90/95% latency 2508.42 2622.62 2735.88 Note especially the effect on latency tail (95th percentile). This seems to provide a nice performance improvement and is consistent in the tests I ran. Presumably, this would provide the greatest benfits in the presence of an application workload stressing the cache and a lot of transmit data happening.

Note: 1. It does NOT enforce the restriction on the relationship max_age and forward delay or hello time because in existing implementation these are set as independant operations. 2. If STP is disabled, there is no restriction on forward delay 3. No restriction on holding time because users use Linux code to act as hub or be sticky. 4. Although standard allow 0-255, Linux only allows 0-63 for port priority because more bits are reserved for port number.
