2013-01-10net: Add support for XPS without sysfs being definedAlexander Duyck
This patch makes it so that we can support transmit packet steering without sysfs needing to be enabled. The reason for making this change is to make it so that a driver can make use of the XPS even while the sysfs portion of the interface is not present.

2013-01-10net: Rewrite netif_set_xps_queues to address several issuesAlexander Duyck
This change is meant to address several issues I found within the netif_set_xps_queues function. If the allocation of one of the maps to be assigned to new_dev_maps failed we could end up with the device map in an inconsistent state since we had already worked through a number of CPUs and removed or added the queue. To address that I split the process into several steps. The first of which is just the allocation of updated maps for CPUs that will need larger maps to store the queue. By doing this we can fail gracefully without actually altering the contents of the current device map. The second issue I found was the fact that we were always allocating a new device map even if we were not adding any queues. I have updated the code so that we only allocate a new device map if we are adding queues, otherwise if we are not adding any queues to CPUs we just skip to the removal process. The last change I made was to reuse the code from remove_xps_queue to remove the queue from the CPU. By making this change we can be consistent in how we go about adding and removing the queues from the CPUs. Signed-off-by: Alexander Duyck <alexander.h.duyck@intel.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2013-01-10net: Rewrite netif_reset_xps_queue to allow for better code reuseAlexander Duyck
This patch does a minor refactor on netif_reset_xps_queue to address a few items I noticed. First is the fact that we are doing removal of queues in both netif_reset_xps_queue and netif_set_xps_queue. Since there is no need to have the code in two places I am pushing it out into a separate function and will come back in another patch and reuse the code in netif_set_xps_queue. The second item this change addresses is the fact that the Tx queues were not getting their numa_node value cleared as a part of the XPS queue reset. This patch resolves that by resetting the numa_node value if the dev_maps value is set. Signed-off-by: Alexander Duyck <alexander.h.duyck@intel.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2013-01-10net: Add functions netif_reset_xps_queue and netif_set_xps_queueAlexander Duyck
This patch adds two functions, netif_reset_xps_queue and netif_set_xps_queue. The main idea behind these two functions is to provide a mechanism through which drivers can update their defaults in regards to XPS. Currently no such mechanism exists and as a result we cannot use XPS for things such as ATR which would require a basic configuration to start in which the Tx queues are mapped to CPUs via a 1:1 mapping. With this change I am making it possible for drivers such as ixgbe to be able to use the XPS feature by controlling the default configuration.

2013-01-10net: Split core bits of netdev_pick_tx into __netdev_pick_txAlexander Duyck

2013-01-10net_sched: more precise pkt_len computationEric Dumazet
One long standing problem with TSO/GSO/GRO packets is that skb->len doesn't represent a precise amount of bytes on wire. Headers are only accounted for the first segment. For TCP, thats typically 66 bytes per 1448 bytes segment missing, an error of 4.5 % for normal MSS value. As consequences : 1) TBF/CBQ/HTB/NETEM/... can send more bytes than the assigned limits. 2) Device stats are slightly under estimated as well. Fix this by taking account of headers in qdisc_skb_cb(skb)->pkt_len computation. Packet schedulers should use qdisc pkt_len instead of skb->len for their bandwidth limitations, and TSO enabled devices drivers could use pkt_len if their statistics are not hardware assisted, and if they don't scratch skb->cb[] first word. Both egress and ingress paths work, thanks to commit fda55eca5a (net: introduce skb_transport_header_was_set()) : If GRO built a GSO packet, it also set the transport header for us.

2013-01-10ipv6: use addrconf_get_prefix_route for prefix route lookup [v2]Romain Kuntz
Replace ip6_route_lookup() with addrconf_get_prefix_route() when looking up for a prefix route. This ensures that the connected prefix is looked up in the main table, and avoids the selection of other matching routes located in different tables as well as blackhole or prohibited entries. In addition, this fixes an Opps introduced by commit 64c6d08e (ipv6: del unreachable route when an addr is deleted on lo), that would occur when a blackhole or prohibited entry is selected by ip6_route_lookup(). Such entries have a NULL rt6i_table argument, which is accessed by __ip6_del_rt() when trying to lock rt6i_table->tb6_lock. The function addrconf_is_prefix_route() is not used anymore and is removed.

2013-01-10Bluetooth: Fix sending incorrect new_settings for mgmt_set_poweredJohan Hedberg
The socket from which a mgmt_set_powered command was received should only receive the command response but no new_settings event. The mgmt_powered() function which is used to handle the situation with the HCI_AUTO_OFF flag tries to check for a pending command to know which socket to skip the event for, but since the pending command hasn't been added this will not happen. This patch fixes the issue by adding the pending command for the HCI_AUTO_OFF case and thereby ensures that mgmt_powered() will skip the right socket when sending the new_settings event, but still send the proper response to the socket where the command came from.

The concept of Class of Device only exists for BR/EDR controllers. The mgmt_set_dev_class command should therefore return a proper "not supported" error if it is attempted for a controller that doesn't support BR/EDR (e.g. a single mode LE-only one).

2013-01-10Bluetooth: Fix checking for valid device class valuesJohan Hedberg
The two lowest bits of the minor device class value are reserved and should be zero, and the three highest bits of the major device class likewise. The management code should therefore test for this and return a proper "invalid params" error if the condition is not met.

In ipv6_recv_error(), addr_offset points to daddr field of the ip header. To get ipv6 header, use container_of() macro instead of substracting magic number (24). Signed-off-by: YOSHIFUJI Hideaki <yoshfuji@linux-ipv6.org> Signed-off-by: David S. Miller <davem@davemloft.net>
