2010-02-11ethtool: Use explicit designated initializers for .cmdRoland Dreier1-5/+5
Initialize the .cmd member of various ethtool using a designated struct initializer rather. This makes things a teeny bit more robust, although the chance of a struct layout changing is extremely remote, and also makes the code a little easier to read.

2010-02-11ethtool: Introduce n-tuple filter programming supportPeter P Waskiewicz Jr4-1/+386
This patchset enables the ethtool layer to program n-tuple filters to an underlying device. The idea is to allow capable hardware to have static rules applied that can assist steering flows into appropriate queues. Hardware that is known to support these types of filters today are ixgbe and niu.

2010-02-11sky2: receive checksum refactoringstephen hemminger1-31/+28
Break the largish case for handling receive checksum into a separate function, and if there is a problem use dev_XXX routines to show which hardware is the problem. Turn one corner case into a BUG(). This only happens if the driver is expecting one behavior but the chip does the old behavior; only ever saw this when bringing up a new chip type and driver was buggy.

2010-02-08netfilter: nf_conntrack: fix hash resizing with namespacesPatrick McHardy10-47/+49
As noticed by Jon Masters <jonathan@jonmasters.org>, the conntrack hash size is global and not per namespace, but modifiable at runtime through /sys/module/nf_conntrack/hashsize. Changing the hash size will only resize the hash in the current namespace however, so other namespaces will use an invalid hash size. This can cause crashes when enlarging the hashsize, or false negative lookups when shrinking it. Move the hash size into the per-namespace data and only use the global hash size to initialize the per-namespace value when instanciating a new namespace. Additionally restrict hash resizing to init_net for now as other namespaces are not handled currently. Cc: stable@kernel.org Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S.

2010-02-08netfilter: nf_conntrack: per netns nf_conntrack_cachepEric Dumazet2-16/+25
nf_conntrack_cachep is currently shared by all netns instances, but because of SLAB_DESTROY_BY_RCU special semantics, this is wrong. If we use a shared slab cache, one object can instantly flight between one hash table (netns ONE) to another one (netns TWO), and concurrent reader (doing a lookup in netns ONE, 'finding' an object of netns TWO) can be fooled without notice, because no RCU grace period has to be observed between object freeing and its reuse. We dont have this problem with UDP/TCP slab caches because TCP/UDP hashtables are global to the machine (and each object has a pointer to its netns). If we use per netns conntrack hash tables, we also *must* use per netns conntrack slab caches, to guarantee an object can not escape from one namespace to another one.

2010-02-08netfilter: nf_conntrack: fix memory corruption with multiple namespacesPatrick McHardy1-12/+12
As discovered by Jon Masters <jonathan@jonmasters.org>, the "untracked" conntrack, which is located in the data section, might be accidentally freed when a new namespace is instantiated while the untracked conntrack is attached to a skb because the reference count it re-initialized. The best fix would be to use a seperate untracked conntrack per namespace since it includes a namespace pointer. Unfortunately this is not possible without larger changes since the namespace is not easily available everywhere we need it. For now move the untracked conntrack initialization to the init_net setup function to make sure the reference count is not re-initialized and handle cleanup in the init_net cleanup function to make sure namespaces can exit properly while the untracked conntrack is in use in other namespaces.

2010-02-05packet: Add GSO/csum offload support.Sridhar Samudrala2-11/+177
This patch adds GSO/checksum offload to af_packet sockets using virtio_net_hdr. Based on Rusty's patch to add this support to tun. It allows GSO/checksum offload to be enabled when using raw socket backend with virtio_net. Adds PACKET_VNET_HDR socket option to prepend virtio_net_hdr in the receive path and process/skip virtio_net_hdr in the send path. This option is only allowed with SOCK_RAW sockets attached to ethernet type devices. v2 updates ---------- Michael's Comments - Perform length check in packet_snd() when GSO is off even when vnet_hdr is present. - Check for SKB_GSO_FCOE type and return -EINVAL - don't allow tx/rx ring when vnet_hdr is enabled.
