2015-08-28sfc: Allow driver to cope with a lower number of VIs than it needs for RSSShradha Shah6-28/+72
Previously, the driver would refuse to load if it couldn't secure enough VIs from the MC to fulfill its RSS requirements. This was causing probe to fail on later functions in configurations where we'd run out of VIs, such as having many VFs. This change allows the driver to load with fewer VIs, down to a minimum of 2. A warning will be printed saying that RSS requirements were not met, possibly affecting performance. efx->max_tx_channels needs to be set to avoid going down the failure path in efx_probe_nic() immediately in the loop after the probe() NIC-type function. Also, Set rc=ENOSPC when bombing out of efx_probe_nic due to lack of VIs. Signed-off-by: Shradha Shah <sshah@solarflare.com> Signed-off-by: David S. Miller <davem@davemloft.net>

Forcing uninitialized state allows us to upgrade and reinitialize the adapter. FW_VERSION_T4 = 1.4.0.0 FW_VERSION_T5 = 0.0.0.0 FW_VERSION_T6 = 0.0.0.0 At this point driver supports above and greater than above version.

2015-08-28net: Refactor inetpeer address structDavid Ahern1-16/+19
Move the inetpeer_addr_base union to inetpeer_addr and drop inetpeer_addr_base. Both the a6 and in6_addr overlays are not needed; drop the __be32 version and rename in6 to a6 for consistency with ipv4. Add a new u32 array to the union which removes the need for the typecast in the compare function and the use of a consistent arg for both ipv4 and ipv6 addresses which makes the compare function more readable.

2015-08-28IGMP: Inhibit reports for local multicast groupsPhilip Downey3-1/+33
The range of addresses between 224.0.0.0 and 224.0.0.255 inclusive, is reserved for the use of routing protocols and other low-level topology discovery or maintenance protocols, such as gateway discovery and group membership reporting. Multicast routers should not forward any multicast datagram with destination addresses in this range, regardless of its TTL. Currently, IGMP reports are generated for this reserved range of addresses even though a router will ignore this information since it has no purpose. However, the presence of reserved group addresses in an IGMP membership report uses up network bandwidth and can also obscure addresses of interest when inspecting membership reports using packet inspection or debug messages. Although the RFCs for the various version of IGMP (e.g.RFC 3376 for v3) do not specify that the reserved addresses be excluded from membership reports, it should do no harm in doing so. In particular there should be no adverse effect in any IGMP snooping functionality since 224.0.0.x is specifically excluded as per RFC 4541 (IGMP and MLD Snooping Switches Considerations) section 2.1.2. Data Forwarding Rules: 2) Packets with a destination IP (DIP) address in the 224.0.0.X range which are not IGMP must be forwarded on all ports. IGMP reports for local multicast groups can now be optionally inhibited by means of a system control variable (by setting the value to zero) e.g.: echo 0 > /proc/sys/net/ipv4/igmp_link_local_mcast_reports To retain backwards compatibility the previous behaviour is retained by default on system boot or reverted by setting the value back to non-zero e.g.: echo 1 > /proc/sys/net/ipv4/igmp_link_local_mcast_reports Signed-off-by: Philip Downey <pdowney@brocade.com> Signed-off-by: David S.

2015-08-28r8169: Add software counter for multicast packagesCorinna Vinschen1-5/+4
The multicast hardware counter on 8168/8111 chips is only 32 bit while the statistics in struct rtnl_link_stats64 are 64 bit. Given that statistics are requested on an irregular basis, an overflow of the hardware counter can go unnoticed. To count even very large numbers of multicast packets reliably, add a software counter and remove previously applied code to fill the multicast field requested by @rtl8169_get_stats64 with the values read from the rx_multicast hardware counter.

2015-08-27net: fix IFF_NO_QUEUE for drivers using alloc_netdevPhil Sutter1-1/+1
Printing a warning in alloc_netdev_mqs() if tx_queue_len is zero and IFF_NO_QUEUE not set is not appropriate since drivers may use one of the alloc_netdev* macros instead of alloc_etherdev*, thereby not intentionally leaving tx_queue_len uninitialized. Instead check here if tx_queue_len is zero and set IFF_NO_QUEUE, so the value of tx_queue_len can be ignored in net/sched_generic.c.

2015-08-27sctp: donot reset the overall_error_count in SHUTDOWN_RECEIVE statelucien1-1/+1
Commit f8d960524328 ("sctp: Enforce retransmission limit during shutdown") fixed a problem with excessive retransmissions in the SHUTDOWN_PENDING by not resetting the association overall_error_count. This allowed the association to better enforce assoc.max_retrans limit. However, the same issue still exists when the association is in SHUTDOWN_RECEIVED state. In this state, HB-ACKs will continue to reset the overall_error_count for the association would extend the lifetime of association unnecessarily. This patch solves this by resetting the overall_error_count whenever the current state is small then SCTP_STATE_SHUTDOWN_PENDING. As a small side-effect, we end up also handling SCTP_STATE_SHUTDOWN_ACK_SENT and SCTP_STATE_SHUTDOWN_SENT states, but they are not really impacted because we disable Heartbeats in those states.

While looking into fixing the local entries scalability issue I noticed that the structure is badly arranged because vlan_id would fall in a second cache line while keeping rcu which is used only when deleting in the first, so re-arrange the structure and push rcu to the end so we can get 16 bytes which can be used for other fields (by pushing rcu fully in the second 64 byte chunk).

This enables bridge vlan_protocol to be configured through netlink. When CONFIG_BRIDGE_VLAN_FILTERING is disabled, kernel behaves the same way as this feature is not implemented. Signed-off-by: Toshiaki Makita <makita.toshiaki@lab.ntt.co.jp> Signed-off-by: David S. Miller <davem@davemloft.net>

2015-08-27smsc911x: Ignore error return from device_get_phy_mode()Guenter Roeck1-6/+8
Commit 62ee783bf1f8 ("smsc911x: Fix crash seen if neither ACPI nor OF is configured or used") introduces an error check for the return value from device_get_phy_mode() and bails out if there is an error. Unfortunately, there are configurations where no phy is configured. Those configurations now fail. To fix the problem, accept error returns from device_get_phy_mode(), and use the return value from device_property_read_u32() to determine if there is a suitable firmware interface to read the configuration.

Return -ENXIO if device property array access functions don't find a suitable firmware interface. This lets drivers decide if they should use available platform data instead. Cc: Rafael J.

2015-08-27net: sched: consolidate tc_classify{,_compat}Daniel Borkmann16-47/+40
For classifiers getting invoked via tc_classify(), we always need an extra function call into tc_classify_compat(), as both are being exported as symbols and tc_classify() itself doesn't do much except handling of reclassifications when tp->classify() returned with TC_ACT_RECLASSIFY. CBQ and ATM are the only qdiscs that directly call into tc_classify_compat(), all others use tc_classify(). When tc actions are being configured out in the kernel, tc_classify() effectively does nothing besides delegating. We could spare this layer and consolidate both functions. pktgen on single CPU constantly pushing skbs directly into the netif_receive_skb() path with a dummy classifier on ingress qdisc attached, improves slightly from 22.3Mpps to 23.1Mpps.

2015-08-27sctp: asconf's process should verify address parameter is in the beginninglucien1-0/+7
in sctp_process_asconf(), we get address parameter from the beginning of the addip params. but we never check if it's really there. if the addr param is not there, it still can pass sctp_verify_asconf(), then to be handled by sctp_process_asconf(), it will not be safe. so add a code in sctp_verify_asconf() to check the address parameter is in the beginning, or return false to send abort. note that this can also detect multiple address parameters, and reject it.
