2013-08-23mac80211: move setting WIPHY_FLAG_SUPPORTS_SCHED_SCAN into driversJohannes Berg
mac80211 currently sets WIPHY_FLAG_SUPPORTS_SCHED_SCAN based on whether the start_sched_scan operation is supported or not, but that will not be correct for all drivers, we're adding scheduled scan to the iwlmvm driver but it depends on firmware support. Therefore, move setting WIPHY_FLAG_SUPPORTS_SCHED_SCAN into the drivers so that they can control it regardless of implementing the operation. This currently only affects the TI drivers since they're the only ones implementing scheduled scan (in a mac80211 driver.)

Pull networking updates from David Miller: "This is a re-do of the net-next pull request for the current merge window. The only difference from the one I made the other day is that this has Eliezer's interface renames and the timeout handling changes made based upon your feedback, as well as a few bug fixes that have trickeled in. Highlights: 1) Low latency device polling, eliminating the cost of interrupt handling and context switches. Allows direct polling of a network device from socket operations, such as recvmsg() and poll(). Currently ixgbe, mlx4, and bnx2x support this feature. Full high level description, performance numbers, and design in commit 0a4db187a999 ("Merge branch 'll_poll'") From Eliezer Tamir. 2) With the routing cache removed, ip_check_mc_rcu() gets exercised more than ever before in the case where we have lots of multicast addresses. Use a hash table instead of a simple linked list, from Eric Dumazet. 3) Add driver for Atheros CQA98xx 802.11ac wireless devices, from Bartosz Markowski, Janusz Dziedzic, Kalle Valo, Marek Kwaczynski, Marek Puzyniak, Michal Kazior, and Sujith Manoharan. 4) Support reporting the TUN device persist flag to userspace, from Pavel Emelyanov. 5) Allow controlling network device VF link state using netlink, from Rony Efraim. 6) Support GRE tunneling in openvswitch, from Pravin B Shelar. 7) Adjust SOCK_MIN_RCVBUF and SOCK_MIN_SNDBUF for modern times, from Daniel Borkmann and Eric Dumazet. 8) Allow controlling of TCP quickack behavior on a per-route basis, from Cong Wang. 9) Several bug fixes and improvements to vxlan from Stephen Hemminger, Pravin B Shelar, and Mike Rapoport. In particular, support receiving on multiple UDP ports. 10) Major cleanups, particular in the area of debugging and cookie lifetime handline, to the SCTP protocol code. From Daniel Borkmann. 11) Allow packets to cross network namespaces when traversing tunnel devices. From Nicolas Dichtel. 12) Allow monitoring netlink traffic via AF_PACKET sockets, in a manner akin to how we monitor real network traffic via ptype_all. From Daniel Borkmann. 13) Several bug fixes and improvements for the new alx device driver, from Johannes Berg. 14) Fix scalability issues in the netem packet scheduler's time queue, by using an rbtree. From Eric Dumazet. 15) Several bug fixes in TCP loss recovery handling, from Yuchung Cheng. 16) Add support for GSO segmentation of MPLS packets, from Simon Horman. 17) Make network notifiers have a real data type for the opaque pointer that's passed into them. Use this to properly handle network device flag changes in arp_netdev_event(). From Jiri Pirko and Timo Teräs. 18) Convert several drivers over to module_pci_driver(), from Peter Huewe. 19) tcp_fixup_rcvbuf() can loop 500 times over loopback, just use a O(1) calculation instead. From Eric Dumazet. 20) Support setting of explicit tunnel peer addresses in ipv6, just like ipv4. From Nicolas Dichtel. 21) Protect x86 BPF JIT against spraying attacks, from Eric Dumazet. 22) Prevent a single high rate flow from overruning an individual cpu during RX packet processing via selective flow shedding. From Willem de Bruijn. 23) Don't use spinlocks in TCP md5 signing fast paths, from Eric Dumazet. 24) Don't just drop GSO packets which are above the TBF scheduler's burst limit, chop them up so they are in-bounds instead. Also from Eric Dumazet. 25) VLAN offloads are missed when configured on top of a bridge, fix from Vlad Yasevich. 26) Support IPV6 in ping sockets. From Lorenzo Colitti. 27) Receive flow steering targets should be updated at poll() time too, from David Majnemer. 28) Fix several corner case regressions in PMTU/redirect handling due to the routing cache removal, from Timo Teräs. 29) We have to be mindful of ipv4 mapped ipv6 sockets in upd_v6_push_pending_frames(). From Hannes Frederic Sowa. 30) Fix L2TP sequence number handling bugs, from James Chapman." * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-next: (1214 commits) drivers/net: caif: fix wrong rtnl_is_locked() usage drivers/net: enic: release rtnl_lock on error-path vhost-net: fix use-after-free in vhost_net_flush net: mv643xx_eth: do not use port number as platform device id net: sctp: confirm route during forward progress virtio_net: fix race in RX VQ processing virtio: support unlocked queue poll net/cadence/macb: fix bug/typo in extracting gem_irq_read_clear bit Documentation: Fix references to defunct linux-net@vger.kernel.org net/fs: change busy poll time accounting net: rename low latency sockets functions to busy poll bridge: fix some kernel warning in multicast timer sfc: Fix memory leak when discarding scattered packets sit: fix tunnel update via netlink dt:net:stmmac: Add dt specific phy reset callback support. dt:net:stmmac: Add support to dwmac version 3.610 and 3.710 dt:net:stmmac: Allocate platform data only if its NULL. net:stmmac: fix memleak in the open method ipv6: rt6_check_neigh should successfully verify neigh if no NUD information are available net: ipv6: fix wrong ping_v6_sendmsg return value ...

2013-06-17wlcore: fix occasional AP TX stop after recoveryVictor Goldenshtein
The fw_status wasn't zeroed during allocation, resulting in uninitialized var usage, and finally causing AP traffic stop after recovery. The wrong value in fw_status_2->counters.tx_lnk_free_pkts led to a bad lnk->allocated_pkts calculation in wlcore_fw_status(), causing wl18xx_lnk_low_prio() to return FALSE (lnk->allocated_pkts > thold). This eventually blocked the link in wlcore_tx_work_locked(), as wl1271_skb_dequeue() continuously returned NULL. Fix it by zeroing wl->fw_status_1/2 during allocation.

2013-06-17wl18xx: FDSP Code RAM Corruption fixIdo Reis
In PG2.0 there is an issue where PHY's FDSP Code RAM sometimes gets corrupted when exiting from ELP mode. This issue is related to FDSP Code RAM clock implementation. PG2.1 introduces a HW fix for this issue that requires the driver to change the FDSP Code Ram clock settings (mux it to ATGP clock instead of its own clock). This workaround uses PHY_FPGA_SPARE_1 register and is relevant to WL8 PG2.1 devices. The fix is also backward compatible with older PG2.0 devices where the register PHY_FPGA_SPARE_1 is not used and not connected. The fix is done in the wl18xx_pre_upload function (must be performed before uploading the FW code) and includes the following steps: 1. Disable FDSP clock 2. Set ATPG clock toward FDSP Code RAM rather than its own clock. 3. Re-enable FDSP clock Signed-off-by: Yair Shapira <yair.shapira@ti.com> Signed-off-by: Ido Reis <idor@ti.com> Signed-off-by: Arik Nemtsov <arik@wizery.com> Signed-off-by: Luciano Coelho <coelho@ti.com>

2013-04-16mac80211: support secondary channel offset in CSAJohannes Berg
Add support for the secondary channel offset IE in channel switch announcements. This is necessary for proper handling of CSA on HT access points. For this to work it is also necessary to convert everything here to use chandef structs instead of just channels. The driver updates aren't really correct though. In particular, the TI wl18xx driver update can't possibly be right since it just ignores the new channel width for lack of firmware API. Signed-off-by: Johannes Berg <johannes.berg@intel.com>

2013-03-25wlcore: consolidate tx_seq handling on recoveryArik Nemtsov
Accumulate the total number of sent packets per-link to find out how far the encryption sequence number has progressed. Use this number as the initial security sequence number after recovery. This consolidates security sequence handling for both chip families, as we no longer have to rely on 12xx specific Tx completion. A fortunate side effect of this is correct management of seq numbers for AP roles and multi-role scenarios. When a link is removed we save the last seq number on a persistent part of the wlvif. This helps the data survive through recoveries/suspends, which also entail changes in the hlid of the link. This functionality is STA only currently.
