      ath10k: enable adaptive CCA · 62f77f09
      Maharaja authored
      European Union has made it mandatory that all devices working in 2.4 GHz
      has to adhere to the ETSI specification (ETSI EN 300 328 V1.9.1)
      beginnig this year. The standard basically speaks about interferences
      in 2.4Ghz band.
      For example, when 802.11 device detects interference, TX must be stopped
      as long as interference is present.
      
      Adaptive CCA is a feature, when enabled the device learns from the
      environment and configures CCA levels adaptively. This will improve
      detecting interferences and the device can stop trasmissions till the
      interference is present eventually leading to good performances in
      varying interference conditions.
      
      The patch includes code for enabling adaptive CCA for 10.2.4 firmware on
      QCA988X.

      ssb: pick PCMCIA host code support from b43 driver · 399500da
      Rafał Miłecki authored
      ssb bus can be found on various "host" devices like PCI/PCMCIA/SDIO.
      Every ssb bus contains cores AKA devices.
      The main idea is to have ssb driver scan/initialize bus and register
      ready-to-use cores. This way ssb drivers can operate on a single core
      mostly ignoring underlaying details.
      
      For some reason PCMCIA support was split between ssb and b43. We got
      PCMCIA host device probing in b43, then bus scanning in ssb and then
      wireless core probing back in b43. The truth is it's very unlikely we
      will ever see PCMCIA ssb device with no 802.11 core but I still don't
      see any advantage of the current architecture.
      
      With proposed change we get the same functionality with a simpler
      architecture, less Kconfig symbols, one killed EXPORT and hopefully
      cleaner b43. Since b43 supports both: ssb & bcma I prefer to keep ssb
      specific code in ssb driver.
      
      This mostly moves code from b43's pcmcia.c to bridge_pcmcia_80211.c. We
      already use similar solution with b43_pci_bridge.c. I didn't use "b43"
      in name of this new file as in theory any driver can operate on wireless
      core.

      mwifiex: toggle carrier state in start_ap/stop_ap. · 0117e78a
      Marty Faltesek authored
      In uap mode the carrier is not enabled until after the first STA joins.
      The carrier triggers the bridge to start its state machine, and if STP
      is enabled, it takes 4 seconds as it transitions from disabled to
      forwarding. During this time the bridge drops all traffic, and the EAPOL
      handshake times out after 3 seconds, preventing stations from joining.
      
      Follow the logic used in mac80211 and start the carrier in start_ap
      and disable it in stop_ap. This has a nice benefit of allowing the
      first station connection time to be reduced by up to 75% when STP is
      in use.

      wcn36xx: introduce per-channel ring buffer locks · 8e8e54c4
      Bob Copeland authored
      wcn36xx implements a ring buffer for transmitted frames for each
      (high and low priority) DMA channel.  The ring buffers are lockless:
      new frames are inserted at the head of the queue, while finished
      packets are reaped from the tail.
      
      Unfortunately, the list manipulations are missing any kind of barriers
      so are susceptible to various races: for example, a TX completion
      handler might read an updated desc->ctrl before the head has actually
      advanced, and then null out the ctl->skb pointer while it is still
      being used in the TX path.
      
      Simplify things here by adding a spin lock when traversing the ring.
      This change increased stability for me without adding any noticeable
      overhead on my platform (xperia z).

      ath9k: fix phyerror codes · 56bae464
      Zefir Kurtisi authored
      Some of the ath9k_phyerr enums were wrong from the
      beginning (and even before). Most of the time the
      codes were used for counters to be displayed over
      debugfs, which made this a non-functional issue.
      
      Some (e.g. ATH9K_PHYERR_FALSE_RADAR_EXT) are used
      for radar detection and require the correct code
      to work as intended.
      
      This patch includes:
      a) fixes
        ATH9K_PHYERR_FALSE_RADAR_EXT:    24 => 36
        ATH9K_PHYERR_CCK_LENGTH_ILLEGAL: 32 => 28
        ATH9K_PHYERR_CCK_POWER_DROP:     33 => 29
        ATH9K_PHYERR_HT_CRC_ERROR:       34 => 32
        ATH9K_PHYERR_HT_LENGTH_ILLEGAL:  35 => 33
        ATH9K_PHYERR_HT_RATE_ILLEGAL:    36 => 34
      
      b) extensions
        ATH9K_PHYERR_CCK_BLOCKER = 24
        ATH9K_PHYERR_HT_ZLF      = 35
        ATH9K_PHYERR_GREEN_FIELD = 37
      
      Aside from the correction and completion made in
      the enum, the patch also extends the display of
      the related counters in the debugfs.

      airo: fix scan after SIOCSIWAP (airo_set_wap) · dae0412d
      Ondrej Zary authored
      SIOCSIWAP (airo_set_wap) affects scan: only the AP specified by
      SIOCSIWAP is present in scan results.
      
      This makes NetworkManager work for the first time but then unable to
      find any other APs.
      
      Clear APList before starting scan and set it back after scan completes
      to work-around the problem.
      
      To avoid losing packets during scan, modify disable_MAC() to omit
      netif_carrier_off() call when lock == 2.

      seccomp, ptrace: add support for dumping seccomp filters · f8e529ed
      Tycho Andersen authored
      This patch adds support for dumping a process' (classic BPF) seccomp
      filters via ptrace.
      
      PTRACE_SECCOMP_GET_FILTER allows the tracer to dump the user's classic BPF
      seccomp filters. addr should be an integer which represents the ith seccomp
      filter (0 is the most recently installed filter). data should be a struct
      sock_filter * with enough room for the ith filter, or NULL, in which case
      the filter is not saved. The return value for this command is the number of
      BPF instructions the program represents, or negative in the case of errors.
      Command specific errors are ENOENT: which indicates that there is no ith
      filter in this seccomp tree, and EMEDIUMTYPE, which indicates that the ith
      filter was not installed as a classic BPF filter.
      
      A caveat with this approach is that there is no way to get explicitly at
      the heirarchy of seccomp filters, and users need to memcmp() filters to
      decide which are inherited. This means that a task which installs two of
      the same filter can potentially confuse users of this interface.
      
      v2: * make save_orig const
          * check that the orig_prog exists (not necessary right now, but when
             grows eBPF support it will be)
          * s/n/filter_off and make it an unsigned long to match ptrace
          * count "down" the tree instead of "up" when passing a filter offset
      
      v3: * don't take the current task's lock for inspecting its seccomp mode
          * use a 0x42** constant for the ptrace command value
      
      v4: * don't copy to userspace while holding spinlocks
      
      v5: * add another condition to WARN_ON
      
      v6: * rebase on net-next

      mpls: reduce memory usage of routes · cf4b24f0
      Robert Shearman authored
      Nexthops for MPLS routes have a via address field sized for the
      largest via address that is expected, which is 32 bytes. This means
      that in the most common case of having ipv4 via addresses, 28 bytes of
      memory more than required are used per nexthop. In the other common
      case of an ipv6 nexthop then 16 bytes more than required are
      used. With large numbers of MPLS routes this extra memory usage could
      start to become significant.
      
      To avoid allocating memory for a maximum length via address when not
      all of it is required and to allow for ease of iterating over
      nexthops, then the via addresses are changed to be stored in the same
      memory block as the route and nexthops, but in an array after the end
      of the array of nexthops. New accessors are provided to retrieve a
      pointer to the via address.
      
      To allow for O(1) access without having to store a pointer or offset
      per nh, the via address for each nexthop is sized according to the
      maximum via address for any nexthop in the route, which is stored in a
      new route field, rt_max_alen, but this is in an existing hole in
      struct mpls_route so it doesn't increase the size of the
      structure. Each via address is ensured to be aligned to VIA_ALEN_ALIGN
      to account for architectures that don't allow unaligned accesses.

      sock: don't enable netstamp for af_unix sockets · 080a270f
      Hannes Frederic Sowa authored
      netstamp_needed is toggled for all socket families if they request
      timestamping. But some protocols don't need the lower-layer timestamping
      code at all. This patch starts disabling it for af-unix.
      
      E.g. systemd enables timestamping during boot-up on the journald af-unix
      sockets, thus causing the system to globally enable timestamping in the
      lower networking stack. Still, it is very probable that timestamping
      gets activated, by e.g. dhclient or various NTP implementations.

      Merge branch 'qed-driver' · 6092db1a
      David S. Miller authored
      Ariel Elior says:
      
      ====================
      Add new drivers: qed & qede
      
      This series implements the driver set for Qlogic's new QL4xxx series.
      These are 10/20/25/40/50/100 Gig capable converged nics, supporting
      ethernet (obviously), iscsi, fcoe, roce and iwarp protocols.
      
      The overall driver design includes a common module ('qed') and protocol
      specific dependent modules for ethernet ('qede'), fcoe ('qedf'),
      iscsi ('qedi') and roce ('qedr').
      The common module contains all of the common logic, e.g. initialization,
      cleanup, infrastructure for interrupt handling, link management, slowpath
      etc. as well as protocol agnostic features, and supplying an abstraction
      layer for other modules.
      The protocol specific modules can be compiled and operated independently
      of each other, with the exception of the rdma modules which are dependent
      on the ethernet module, in accordance with the kernel rdma stack design.
      
      This series only adds the core and ethernet modules, with basic L2
      capabilities. Future series will add the rest of the modules and enhance
      the L2 functionality.
      
      Ths patch series is constructed of the following patches:
      qed:  Add module with basic common support
      qed:  Add basic L2 interface
      qede: Add basic Network driver
      qed:  Add slowpath L2 support
      qede: Add basic network device support
      qede: Add classification configuration
      qed:  Add link support
      qede: Add support for link
      qed:  Add statistics support
      qede: Add basic ethtool support
      
      This project is a team effort, thanks go to Yuval Mintz, Dmitry Kravkov,
      Michal Kalderon, Tomer Tayar, Manish Chopra, Sudarsana Kalluru,
      Rajesh Borundia, Sony Chacko, Artum Zolotushko, Harish Patil, Rasesh Mody,

      Changes from previos version:
      -----------------------------
      
      From Version 7:
        - Various small fixes according to Dave's suggestions; Largest change
          [code-wise] - don't use tabs for indenting function arguments.
      
      From Version 6:
        - Reduced the number of arguments for functions with exceptionally
          high number of parameters.
      
      From Version 5:
        - Style change and fixes [mostly in 1, 4 and 7].
          Thanks go to Francois Romieu, a mere mortal. ;-)
      
      From Version 4:
        - Drop dependency for x86_64.
      
      From Version 3:
        - Limit support of initial submission to x86_64.
        - Fix endian problems appearing via sparse [although no BE support yet].
        - Fix small issues suggested by the kbuild test robot.
      
      From Version 2:
        - Removed U64_{HI,LO}; Using {upper,lower}_32_bits instead.
        - Use regular napi weight definition.
        - [We still use the __le variants for variables, since we didn't get
           a reply regarding the change into non-user API types].
      
      From Version 1:
        - Removed private license file; Instead revised comments at source headers.

      qede: Add support for link · a2ec6172
      Sudarsana Kalluru authored
      This adds basic link functionality to qede - driver still doesn't provide
      users with an API to change any link property, but it does request qed to
      initialize the link using default configuration, and registers a callback
      that allows it to get link notifications.
      
      This patch adds the ability of the driver to set the carrier as active and
      to enable traffic as a result of async. link notifications.
      Following this patch, driver should be capable of running traffic.

      Physical link is handled by the management Firmware.
      This patch lays the infrastructure for attention handling in the driver,
      as link change notifications arrive via async. attentions,
      as well the handling of such notifications.
      
      This patch also extends the API with the protocol drivers by adding
      registered callbacks which the protocol driver passes to qed in order
      to be notified of async. events originating from the FW/HW.

      The Qlogic Everest Driver for Ethernet is the Ethernet specific module for
      QL4xxx ethernet products by Qlogic.
      
      This patch adds a very minimal PCI driver, one that doesn't yet register
      a network device, but one that does interact with qed and does a basic
      initialization of the HW.

      qed: Add basic L2 interface · 25c089d7
      Yuval Mintz authored
      This patch adds a public API for a network driver to work on top of QED.
      The interface itself is very minimal - it's mostly infrastructure, as the
      only content it has after this patch is a query for HW-based information
      required for the creation of a network interface [I.e., no actual
      protocol-specific configurations are supported].

      qed: Add module with basic common support · fe56b9e6
      Yuval Mintz authored
      The Qlogic Everest Driver is the backend module for the QL4xxx ethernet
      products by Qlogic.
      
      This module serves two main purposes:
       1. It's responsible to contain all the common code that will be shared
          between the various drivers that would be used with said line of
          products. Flows such as chip initialization and de-initialization
          fall under this category.
      
       2. It would abstract the protocol-specific HW & FW components, allowing
          the protocol drivers to have a clean APIs which is detached in its
          slowpath configuration from the actual HSI.
      
      This adds a very basic module without any protocol-specific bits.
      I.e., this adds a basic implementation that almost entirely falls under
      the first category.
