Pull networking fixes from David Miller: "Sorry I let so much accumulate, I was in Buffalo and wanted a few things to cook in my tree for a while before sending to you. Anyways, it's a lot of little things as usual at this stage in the game" 1) Make bonding MAINTAINERS entry reflect reality, from Andy Gospodarek. 2) Fix accidental sock_put() on timewait mini sockets, from Eric Dumazet. 3) Fix crashes in l2tp due to mis-handling of ipv4 mapped ipv6 addresses, from François CACHEREUL. 4) Fix heap overflow in __audit_sockaddr(), from the eagle eyed Dan Carpenter. 5) tcp_shifted_skb() doesn't take handle FINs properly, from Eric Dumazet. 6) SFC driver bug fixes from Ben Hutchings. 7) Fix TX packet scheduling wedge after channel change in ath9k driver, from Felix Fietkau. 8) Fix user after free in BPF JIT code, from Alexei Starovoitov. 9) Source address selection test is reversed in __ip_route_output_key(), fix from Jiri Benc. 10) VLAN and CAN layer mis-size netlink attributes, from Marc Kleine-Budde. 11) Fix permission checks in sysctls to use current_euid() instead of current_uid(). From Eric W Biederman. 12) IPSEC policies can go away while a timer is still pending for them, add appropriate ref-counting to fix, from Steffen Klassert. 13) Fix mis-programming of FDR and RMCR registers on R8A7740 sh_eth chips, from Nguyen Hong Ky and Simon Horman. 14) MLX4 forgets to DMA unmap pages on RX, fix from Amir Vadai. 15) IPV6 GRE tunnel MTU upper limit is miscalculated, from Oussama Ghorbel. 16) Fix typo in fq_change(), we were assigning "initial quantum" to "quantum". From Eric Dumazet. 17) Set a more appropriate sk_pacing_rate for non-TCP sockets, otherwise FQ packet scheduler does not pace those flows properly. Also from Eric Dumazet. 18) rtlwifi miscalculates packet pointers, from Mark Cave-Ayland. 19) l2tp_xmit_skb() can be called from process context, not just softirq context, so we must always make sure to BH disable around it. From Eric Dumazet. 20) On qdisc reset, we forget to purge the RB tree of SKBs in netem packet scheduler. From Stephen Hemminger. 21) Fix info leak in farsync WAN driver ioctl() handler, from Dan Carpenter and Salva Peiró. 22) Fix PHY reset and other issues in dm9000 driver, from Nikita Kiryanov and Michael Abbott. 23) When hardware can do SCTP crc32 checksums, we accidently don't disable the csum offload when IPSEC transformations have been applied. From Fan Du and Vlad Yasevich. 24) Tail loss probing in TCP leaves the socket in the wrong congestion avoidance state. From Yuchung Cheng. 25) In CPSW driver, enable NAPI before interrupts are turned on, from Markus Pargmann. 26) Integer underflow and dual-assignment in YAM hamradio driver, from Dan Carpenter. 27) If we are going to mangle a packet in tcp_set_skb_tso_segs() we must unclone it. This fixes various hard to track down crashes in drivers where the SKBs ->gso_segs was changing right from underneath the driver during TX queueing. From Eric Dumazet. 28) Fix the handling of VLAN IDs, and in particular the special IDs 0 and 4095, in the bridging layer. From Toshiaki Makita. 29) Another info leak, this time in wanxl WAN driver, from Salva Peiró. 30) Fix race in socket credential passing, from Daniel Borkmann. 31) WHen NETLABEL is disabled, we don't validate CIPSO packets properly, from Seif Mazareeb. 32) Fix identification of fragmented frames in ipv4/ipv6 UDP Fragmentation Offload output paths, from Jiri Pirko. 33) Virtual Function fixes in bnx2x driver from Yuval Mintz and Ariel Elior. 34) When we removed the explicit neighbour pointer from ipv6 routes a slight regression was introduced for users such as IPVS, xt_TEE, and raw sockets. We mix up the users requested destination address with the routes assigned nexthop/gateway. From Julian Anastasov and Simon Horman. 35) Fix stack overruns in rt6_probe(), the issue is that can end up doing two full packet xmit paths at the same time when emitting neighbour discovery messages. From Hannes Frederic Sowa. 36) davinci_emac driver doesn't handle IFF_ALLMULTI correctly, from Mariusz Ceier. 37) Make sure to set TCP sk_pacing_rate after the first legitimate RTT sample, from Neal Cardwell. 38) Wrong netlink attribute passed to xfrm_replay_verify_len(), from Steffen Klassert. * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net: (152 commits) ax88179_178a: Add VID:DID for Samsung USB Ethernet Adapter ax88179_178a: Correct the RX error definition in RX header Revert "bridge: only expire the mdb entry when query is received" tcp: initialize passive-side sk_pacing_rate after 3WHS davinci_emac.c: Fix IFF_ALLMULTI setup mac802154: correct a typo in ieee802154_alloc_device() prototype ipv6: probe routes asynchronous in rt6_probe netfilter: nf_conntrack: fix rt6i_gateway checks for H.323 helper ipv6: fill rt6i_gateway with nexthop address ipv6: always prefer rt6i_gateway if present bnx2x: Set NETIF_F_HIGHDMA unconditionally bnx2x: Don't pretend during register dump bnx2x: Lock DMAE when used by statistic flow bnx2x: Prevent null pointer dereference on error flow bnx2x: Fix config when SR-IOV and iSCSI are enabled bnx2x: Fix Coalescing configuration bnx2x: Unlock VF-PF channel on MAC/VLAN config error bnx2x: Prevent an illegal pointer dereference during panic bnx2x: Fix Maximum CoS estimation for VFs drivers: net: cpsw: fix kernel warn during iperf test with interrupt pacing ...

davinci_emac.c: Fix IFF_ALLMULTI setup

2013-10-21T22:56:23Z

When IFF_ALLMULTI flag is set on interface and IFF_PROMISC isn't, emac_dev_mcast_set should only enable RX of multicasts and reset MACHASH registers. It does this, but afterwards it either sets up multicast MACs filtering or disables RX of multicasts and resets MACHASH registers again, rendering IFF_ALLMULTI flag useless. This patch fixes emac_dev_mcast_set, so that multicast MACs filtering and disabling of RX of multicasts are skipped when IFF_ALLMULTI flag is set. Tested with kernel 2.6.37.

bnx2x: Don't pretend during register dump

2013-10-21T22:31:36Z

As part of a register dump, the interface pretends to have the identity of other interfaces of the same physical device in order to perform HW configuration for them - specifically, it needs to prevent attentions from generating on those functions as the register dump accesses registers in common blocks which whose reading might generate an attention. However, such pretension is unsafe - unlike other flows in which the driver uses pretend, during register dump there is no guarantee no other HW access will take place (by other flows). If such access will take place, the HW will be accessed by the wrong interface, and leave both functions in an incorrect state. This patch removes all pretensions from the register dump flow. Instead, it changes initial configuration of attentions such that no fatal attention will be generated for other functions as a result of the register dump (notice however, a debug print claiming an attention from other functions IS possible during the register dump) Signed-off-by: Dmitry Kravkov Signed-off-by: Yuval Mintz Signed-off-by: Ariel Elior Signed-off-by: Eilon Greenstein Signed-off-by: David S.

bnx2x: Lock DMAE when used by statistic flow

2013-10-21T22:31:35Z

bnx2x has several clients to its DMAE machines - all of them with the exception of the statistics flow used the same locking mechanisms to synchronize the DMAE machines' usage. Since statistics (which are periodically entered) use DMAE without taking the locks, they may erase the commands which were previously set - e.g., it may cause a VF to timeout while waiting for a PF answer on the VF-PF channel as that command header would have been overwritten by the statistics' header. This patch makes certain that all flows utilizing DMAE will use the same API, assuring that the locking scheme will be kept by all said flows.

bnx2x: Prevent null pointer dereference on error flow

bnx2x: Fix config when SR-IOV and iSCSI are enabled

2013-10-21T22:31:35Z

Starting with commit b9871bc "bnx2x: VF RSS support - PF side", if a PF will have SR-IOV supported in its PCI configuration space, storage drivers will not work for that interface. This patch fixes the resource calculation to allow such a configuration to properly work. Signed-off-by: Ariel Elior Signed-off-by: Yuval Mintz Signed-off-by: Eilon Greenstein Signed-off-by: David S.

bnx2x: Fix Coalescing configuration

2013-10-21T22:31:35Z

bnx2x drivers configure coalescing incorrectly (e.g., as a result of a call to 'ethtool -c'). Although this is almost invisible to the user (due to NAPI) designated tests will show the configuration is incorrect.
