      mac80211: flush keys for AP mode on ieee80211_do_stop · 10b68487
      Felix Fietkau authored
      Userspace can add keys to an AP mode interface before start_ap has been
      called. If there have been no calls to start_ap/stop_ap in the mean
      time, the keys will still be around when the interface is brought down.

      mac80211_hwsim: release driver when ieee80211_register_hw fails · 805dbe17
      Junjie Mao authored
      The driver is not released when ieee80211_register_hw fails in
      mac80211_hwsim_create_radio, leading to the access to the unregistered (and
      possibly freed) device in platform_driver_unregister:

      mac80211: minstrels: fix buffer overflow in HT debugfs rc_stats · 11b2357d
      Karl Beldan authored
      ATM an HT rc_stats line is 106 chars.
      Times 8(MCS_GROUP_RATES)*3(SS)*2(GI)*2(BW) + CCK(4), i.e. x100, this is
      well above the current 8192 - sizeof(*ms) currently allocated.
      
      Fix this by squeezing the output as follows (not that we're short on
      memory but this also improves readability and range, the new format adds
      one more digit to *ok/*cum and ok/cum):
      
      - Before (HT) (106 ch):
      type           rate     throughput  ewma prob   this prob  retry   this succ/attempt   success    attempts
      CCK/LP          5.5M           0.0        0.0         0.0      0              0(  0)         0           0
      HT20/LGI ABCDP MCS0            0.0        0.0         0.0      1              0(  0)         0           0
      - After (75 ch):
      type           rate     tpt eprob *prob ret  *ok(*cum)        ok(      cum)
      CCK/LP          5.5M    0.0   0.0   0.0   0    0(   0)         0(        0)
      HT20/LGI ABCDP MCS0     0.0   0.0   0.0   1    0(   0)         0(        0)
      
      - Align non-HT format Before (non-HT) (83 ch):
      rate      throughput  ewma prob  this prob  this succ/attempt   success    attempts
      ABCDP  6         0.0        0.0        0.0             0(  0)         0           0
            54         0.0        0.0        0.0             0(  0)         0           0
      - After (61 ch):
      rate          tpt eprob *prob  *ok(*cum)        ok(      cum)
      ABCDP  1      0.0   0.0   0.0    0(   0)         0(        0)
            54      0.0   0.0   0.0    0(   0)         0(        0)
      
      *This also adds dynamic checks for overflow, lowers the size of the
      non-HT request (allowing > 30 entries) and replaces the buddy-rounded
      allocations (s/sizeof(*ms) + 8192/8192).

      mac80211: fix typo in starting baserate for rts_cts_rate_idx · c7abf25a
      Karl Beldan authored
      It affects non-(V)HT rates and can lead to selecting an rts_cts rate
      that is not a basic rate or way superior to the reference rate (ATM
      rates[0] used for the 1st attempt of the protected frame data).
      
      E.g, assuming drivers register growing (bitrate) sorted tables of
      ieee80211_rate-s, having :
      - rates[0].idx == d'2 and basic_rates == b'10100
      will select rts_cts idx b'10011 & ~d'(BIT(2)-1), i.e. 1, likewise
      - rates[0].idx == d'2 and basic_rates == b'10001
      will select rts_cts idx b'10000
      The first is not a basic rate and the second is > rates[0].
      
      Also, wrt severity of the addressed misbehavior, ATM we only have one
      rts_cts_rate_idx rather than one per rate table entry, so this idx might
      still point to bitrates > rates[1..MAX_RATES].

      nl80211: sanity check the channel switch counter value · 252e07ca
      Luciano Coelho authored
      The nl80211 channel switch count attribute
      (NL80211_ATTR_CH_SWITCH_COUNT) is specified as u32, but the
      specification uses u8 for the counter.  To make sure strange things
      don't happen without informing the user, sanity check the value and
      return -EINVAL if it doesn't fit in u8.

      mac80211: return the vif's chandef in ieee80211_cfg_get_channel() · c12bc488
      Luciano Coelho authored
      The chandef of the channel context a vif is using may be different
      than the chandef of the vif itself.  For instance, the bandwidth used
      by the vif may be narrower than the one configured in the channel
      context.  To avoid confusion, return the vif's chandef in
      ieee80211_cfg_get_channel() instead of the chandef of the channel
      context.

      Pull networking updates from David Miller:
       "Most notable changes in here:
      
         1) By far the biggest accomplishment, thanks to a large range of
            contributors, is the addition of multi-send for transmit.  This is
            the result of discussions back in Chicago, and the hard work of
            several individuals.
      
            Now, when the ->ndo_start_xmit() method of a driver sees
            skb->xmit_more as true, it can choose to defer the doorbell
            telling the driver to start processing the new TX queue entires.
      
            skb->xmit_more means that the generic networking is guaranteed to
            call the driver immediately with another SKB to send.
      
            There is logic added to the qdisc layer to dequeue multiple
            packets at a time, and the handling mis-predicted offloads in
            software is now done with no locks held.
      
            Finally, pktgen is extended to have a "burst" parameter that can
            be used to test a multi-send implementation.
      
            Several drivers have xmit_more support: i40e, igb, ixgbe, mlx4,
            virtio_net
      
            Adding support is almost trivial, so export more drivers to
            support this optimization soon.
      
            I want to thank, in no particular or implied order, Jesper
            Dangaard Brouer, Eric Dumazet, Alexander Duyck, Tom Herbert, Jamal
            Hadi Salim, John Fastabend, Florian Westphal, Daniel Borkmann,
            David Tat, Hannes Frederic Sowa, and Rusty Russell.
      
         2) PTP and timestamping support in bnx2x, from Michal Kalderon.
      
         3) Allow adjusting the rx_copybreak threshold for a driver via
            ethtool, and add rx_copybreak support to enic driver.  From
            Govindarajulu Varadarajan.
      
         4) Significant enhancements to the generic PHY layer and the bcm7xxx
            driver in particular (EEE support, auto power down, etc.) from
            Florian Fainelli.
      
         5) Allow raw buffers to be used for flow dissection, allowing drivers
            to determine the optimal "linear pull" size for devices that DMA
            into pools of pages.  The objective is to get exactly the
            necessary amount of headers into the linear SKB area pre-pulled,
            but no more.  The new interface drivers use is eth_get_headlen().
            From WANG Cong, with driver conversions (several had their own
            by-hand duplicated implementations) by Alexander Duyck and Eric
            Dumazet.
      
         6) Support checksumming more smoothly and efficiently for
            encapsulations, and add "foo over UDP" facility.  From Tom
            Herbert.
      
         7) Add Broadcom SF2 switch driver to DSA layer, from Florian
            Fainelli.
      
         8) eBPF now can load programs via a system call and has an extensive
            testsuite.  Alexei Starovoitov and Daniel Borkmann.
      
         9) Major overhaul of the packet scheduler to use RCU in several major
            areas such as the classifiers and rate estimators.  From John
            Fastabend.
      
        10) Add driver for Intel FM10000 Ethernet Switch, from Alexander
            Duyck.
      
        11) Rearrange TCP_SKB_CB() to reduce cache line misses, from Eric
            Dumazet.
      
        12) Add Datacenter TCP congestion control algorithm support, From
            Florian Westphal.
      
        13) Reorganize sk_buff so that __copy_skb_header() is significantly
            faster.  From Eric Dumazet"

      cxgb4: clean up a type issue · fb5ac0de
      Dan Carpenter authored
      The tx_desc struct holds 8 __be64 values.  The original code in
      ring_tx_db() took a tx_desc pointer then casted it to an int pointer and
      then casted it to a u64 pointer.  It was confusing and triggered some
      static checker warnings.
      
      I have changed the cxgb_pio_copy() function to only take tx_desc
      pointers.  This isn't really a loss of flexibility because anything else
      was buggy to begin with.
      
      I also removed the casting on the destination pointer since that was
      unnecessary and a bit messy.

      r8169:add support for RTL8168EP · 935e2218
      Chun-Hao Lin authored
      RTL8168EP is Realtek PCIe Gigabit Ethernet controller with DASH support.
      It is a successor chip of RTL8168DP.
      
      For RTL8168EP, the read/write ocp register is via eri channel type 2, so I
      move ocp_xxx() related functions under rtl_eri_xxx. And use r8168dp_ocp_xxx()
      for RTL8168DP ocp read/write, r8168ep_ocp_xxx() for RTL8168EP ocp read/write.
      
      The way of checking dash enable is different with RTL8168DP. I use
      r8168dp_check_dash()for RTL8168DP and r8168ep_check_dash() for RTL8168EP,
      to check if dash is enabled.
      
      The driver_start() and driver_stop() of RTL8168EP is also different with
      RTL8168DP. I use rtl8168dp_driver_xxx() for RTL8168DP and
      rtl8168ep_driver_xxx for RTL8168EP.
      
      Right now, RTL8168EP phy mcu did not need firmware code patch, so I did not
      add firmware code for it.
