2013-03-31net: add option to enable error queue packets waking selectKeller, Jacob E
Currently, when a socket receives something on the error queue it only wakes up the socket on select if it is in the "read" list, that is the socket has something to read. It is useful also to wake the socket if it is in the error list, which would enable software to wait on error queue packets without waking up for regular data on the socket. The main use case is for receiving timestamped transmit packets which return the timestamp to the socket via the error queue. This enables an application to select on the socket for the error queue only instead of for the regular traffic. -v2- * Added the SO_SELECT_ERR_QUEUE socket option to every architechture specific file * Modified every socket poll function that checks error queue Signed-off-by: Jacob Keller <jacob.e.keller@intel.com> Cc: Jeffrey Kirsher <jeffrey.t.kirsher@intel.com> Cc: Richard Cochran <richardcochran@gmail.com> Cc: Matthew Vick <matthew.vick@intel.com> Signed-off-by: David S.

2013-03-30macvlan: use the right RCU apiEric Dumazet
Make sure we use proper API to fetch dev->rx_handler_data, instead of ugly casts. Rename macvlan_port_get() to macvlan_port_get_rtnl() to document fact that we hold RTNL when needed, with lockdep support. This removes sparse warnings as well (CONFIG_SPARSE_RCU_POINTER=y) CHECK drivers/net/macvlan.c drivers/net/macvlan.c:706:37: warning: cast removes address space of expression drivers/net/macvlan.c:775:16: warning: cast removes address space of expression drivers/net/macvlan.c:924:16: warning: cast removes address space of expression Signed-off-by: Eric Dumazet <edumazet@google.com> Signed-off-by: David S.

2013-03-30net: reorder some fields of net_deviceEric Dumazet
As time passed, some fields were added in net_device, and not at sensible offsets. Lets reorder some fields to reduce number of cache lines in RX path. Fields not used in data path should be moved out of this critical cache line. In particular, move broadcast[] to the end of the rx section, as it is less used, and ethernet uses only the beginning of the 32bytes field. Before patch : offsetof(struct net_device,dev_addr)=0x258 offsetof(struct net_device,rx_handler)=0x2b8 offsetof(struct net_device,ingress_queue)=0x2c8 offsetof(struct net_device,broadcast)=0x278 After : offsetof(struct net_device,dev_addr)=0x280 offsetof(struct net_device,rx_handler)=0x298 offsetof(struct net_device,ingress_queue)=0x2a8 offsetof(struct net_device,broadcast)=0x2b0 Signed-off-by: Eric Dumazet <edumazet@google.com> Signed-off-by: David S.

2013-03-30ip_gre: don't overwrite iflink during net_dev initAntonio Quartulli
iflink is currently set to 0 in __gre_tunnel_init(). This function is invoked in gre_tap_init() and ipgre_tunnel_init() which are both used to initialise the ndo_init field of the respective net_device_ops structs (ipgre.. and gre_tap..) used by GRE interfaces. However, in netdevice_register() iflink is first set to -1, then ndo_init is invoked and then iflink is assigned to a proper value if and only if it still was -1. Assigning 0 to iflink in ndo_init is therefore first preventing netdev_register() to correctly assign it a proper value and then breaking iflink at all since 0 has not correct meaning. Fix this by removing the iflink assignment in __gre_tunnel_init(). Introduced by c54419321455631079c7d6e60bc732dd0c5914c5 ("GRE: Refactor GRE tunneling code.")

2013-03-29qlcnic: VF-PF communication channel implementationRajesh Borundia
o Adapter provides communication channel between VF and PF. Any control commands from the VF driver are sent to the PF driver through this communication channel. PF driver validates the commands before sending them to the adapter. Similarly PF driver forwards any control command responses to the VF driver through this communication channel. Adapter sends message pending event to VF or PF when there is an outstanding response or a command for VF or PF respectively. When a command or a response is sent over a channel VF or PF cannot send another command or a response until adapter sends a channel free event. Adapter allocates 1K area to VF and PF each for this communication. o Commands and responses are encapsulated in a header. Header determines sequence id, number of fragments, fragment number etc. Signed-off-by: Manish Chopra <manish.chopra@qlogic.com> Signed-off-by: Sucheta Chakraborty <sucheta.chakraborty@qlogic.com> Signed-off-by: Rajesh Borundia <rajesh.borundia@qlogic.com> Signed-off-by: David S.

Commit d0418bb7123f44b23d69ac349eec7daf9103472f (net: sh_eth: Add eth support for R8A7779 device) was a failed attempt to add support for one of members of the R-Car SoC family. That's for three reasons: it treated R8A7779 the same as SH7724 except including quite dirty hack adding ECMR_ELB bit to the mask in sh_eth_set_rate() while not removing ECMR_RTM bit (despite it's reserved in R-Car Ether), and it didn't add a new register offset array despite the closest SH_ETH_REG_FAST_SH4 mapping differs by 0x200 to the offsets all the R-Car Ether registers have, and also some of the registers in this old mapping don't exist on R-Car Ether (due to this, SH7724's 'sh_eth_my_cpu_data' structure is not adequeate for R-Car too).

2013-03-28Merge branch 'master' of ↵David S. Miller
git://git.kernel.org/pub/scm/linux/kernel/git/jkirsher/net-next Jeff Kirsher says: ==================== This series contains updates to e1000e, ixgbe and ixgbevf. Majority of the changes are against e1000e (from Bruce Allan). Bruce adds additional error handling on PHY register access, as well as improve slow performance on 82579 when connected to a 10Mbit hub. In addition, fixes LED blink logic for cathode LED design. Most notable is added EEE support which is enabled by default and the added support for LTR on I217/I218. The ixgbe and ixgbevf from Greg Rose changes the VM so that if a user does not assign a MAC address, the MAC address is set to all zeros instead of a random MAC address. This ensures that we always know when we have a random address and udev won't get upset about it. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

2013-03-27e1000e: slow performance between two 82579 connected via 10Mbit hubBruce Allan
Two 82579 LOMs connected via a 10Mb hub experience extraordinarily low performance. This is because 82579 is excessively aggressive on transmit at 10Mb half-duplex and will not provide sufficient time for the link partner to transmit. When the link partner is also 82579, the result is a lot of collisions (and corresponding re-transmits) that cause the poor performance. To work-around this issue, significantly increase the IPG in the MAC to allow enough gap for the link partner to transmit and reduce the Rx latency in the analog PHY to 0 to reduce the number of collisions.

2013-03-27net: fix compile error of implicit declaration of skb_probe_transport_headerYing Xue
The commit 40893fd(net: switch to use skb_probe_transport_header()) involes a new error accidently. When NET_SKBUFF_DATA_USES_OFFSE is not enabled, below compile error happens: CC net/packet/af_packet.o net/packet/af_packet.c: In function ‘packet_sendmsg_spkt’: net/packet/af_packet.c:1516:2: error: implicit declaration of function ‘skb_probe_transport_header’ [-Werror=implicit-function-declaration] cc1: some warnings being treated as errors make[2]: *** [net/packet/af_packet.o] Error 1 make[1]: *** [net/packet] Error 2 make: *** [net] Error 2 As it seems skb_probe_transport_header() is not related to NET_SKBUFF_DATA_USES_OFFSE, we should move the definition of skb_probe_transport_header() out of scope of NET_SKBUFF_DATA_USES_OFFSE macro.
