      emac: Fix EMAC soft reset on 460EX/GT · 23fbb5a8
      Petri Gynther authored
      Fix EMAC soft reset on 460EX/GT to select the right PHY clock source
      before and after the soft reset.
      
      EMAC with PHY should use the clock from PHY during soft reset.
      EMAC without PHY should use the internal clock during soft reset.
      
      PPC460EX/GT Embedded Processor Advanced User's Manual
      section 28.10.1 Mode Register 0 (EMACx_MR0) states:
      Note: The PHY must provide a TX Clk in order to perform a soft reset
      of the EMAC. If none is present, select the internal clock
      (SDR0_ETH_CFG[EMACx_PHY_CLK] = 1).
      After a soft reset, select the external clock.
      
      Without the fix, 460EX/GT-based boards with RGMII PHYs attached to
      EMACs experience EMAC interrupt storm and system watchdog reset when
      issuing "ifconfig eth0 down" + "ifconfig eth0 up" a few times.
      The system enters endless loop of serving emac_irq() with EMACx_ISR
      register stuck at value 0x10000000 (Rx parity error).
      
      With the fix, the above issue is no longer observed.

      3c59x: fix PCI resource management · 4b264a16
      Sergei Shtylyov authored
      The driver wrongly claimed I/O ports at an address returned by pci_iomap() --
      even if it was passed an MMIO address.  Fix this by claiming/releasing all PCI
      resources in the PCI driver's probe()/remove() methods instead and get rid of
      'must_free_region' flag weirdness (why would Cardbus claim anything for us?).

      ipv6: do not clear pinet6 field · f77d6021
      Eric Dumazet authored
      We have seen multiple NULL dereferences in __inet6_lookup_established()
      
      After analysis, I found that inet6_sk() could be NULL while the
      check for sk_family == AF_INET6 was true.
      
      Bug was added in linux-2.6.29 when RCU lookups were introduced in UDP
      and TCP stacks.
      
      Once an IPv6 socket, using SLAB_DESTROY_BY_RCU is inserted in a hash
      table, we no longer can clear pinet6 field.
      
      This patch extends logic used in commit fcbdf09d
      ("net: fix nulls list corruptions in sk_prot_alloc")
      
      TCP/UDP/UDPLite IPv6 protocols provide their own .clear_sk() method
      to make sure we do not clear pinet6 field.
      
      At socket clone phase, we do not really care, as cloning the parent (non
      NULL) pinet6 is not adding a fatal race.

      macvlan: fix passthru mode race between dev removal and rx path · 233c7df0
      Jiri Pirko authored
      Currently, if macvlan in passthru mode is created and data are rxed and
      you remove this device, following panic happens:
      
      NULL pointer dereference at 0000000000000198
      IP: [<ffffffffa0196058>] macvlan_handle_frame+0x153/0x1f7 [macvlan]
      
      I'm using following script to trigger this:
      <script>
      while [ 1 ]
      do
      	ip link add link e1 name macvtap0 type macvtap mode passthru
      	ip link set e1 up
      	ip link set macvtap0 up
      	IFINDEX=`ip link |grep macvtap0 | cut -f 1 -d ':'`
      	cat /dev/tap$IFINDEX  >/dev/null &
      	ip link del dev macvtap0
      done
      </script>
      
      I run this script while "ping -f" is running on another machine to send
      packets to e1 rx.
      
      Reason of the panic is that list_first_entry() is blindly called in
      macvlan_handle_frame() even if the list was empty. vlan is set to
      incorrect pointer which leads to the crash.
      
      I'm fixing this by protecting port->vlans list by rcu and by preventing
      from getting incorrect pointer in case the list is empty.

      net: fec: enable hardware checksum only on imx6q-fec · 48496255

      Commit 4c09eed9 (net: fec: Enable imx6 enet checksum acceleration.)
      enables hardware checksum acceleration unconditionally for all fec
      variants.  This is inappropriate, because some variants like imx5 have
      no such support on hardware.  Consequently, fec is broken on these
      platforms.  Fix it by enabling hardware checksum only on imx6q-fec type
      of controllers.

      o Fix mailbox response poll time to maximum 5 seconds which
        includes mailbox response time as well as time required for
        processing AEN if any.
      o Driver need to read firmware control mailbox register instead
        of host control mailbox register.

      qlcnic: Fix reset recovery after transmit timeout · 536faa61
      Sony Chacko authored
      o When transmit timeout happens, recovery attempt should start with
        adapter soft reset. If soft reset fails to resume traffic, firmware
        dump will be collected and driver will perform a hard reset of the
        adapter. Reset recovery on 83xx was failing after a hard reset.
        This patch fixes that issue.

      ====================
      Here is a batch of fixes intended for the 3.10 stream.
      
      Amitkumar Karwar provides an mwifiex fix to plug a memory leak when
      the driver is unloaded.
      
      Bing Zhao brings an mwifiex fix for some flag handling that leads to
      log spam and an unusable interface.
      
      Daniel Drake offers an mwifiex fix for multicast filter setup, to
      correctly implement wakeup behaviour for multicast WOL.
      
      Felix Fietkau fixes an ath9k problem that produces logspam and keycache
      errors due to a bad return code.
      
      Stanislaw Gruszka produces an fix for a WARNING from ath5k, and an
      iwl4965 workaround to stop advertising a feature that doesn't work with
      the current mac80211 implementation.
      
      Sujith Manoharan gives us an ath9k fix to reprogram the HW beacon timers
      after a TSF update, and an initvals fix for the AR9565 device.
      
      Thommy Jakobsson fixes an rx descriptor underrun on b43.

      Pull trivial pstore update from Tony Luck:
       "Couple of pstore cleanups"
      
      It turns out that the kmemdup() conversion ends up being undone by the
      fact that the memory block also needed the ecc information (see commit
      bd08ec33: "pstore/ram: Restore ecc information block"), so all that
      remains after merging is the error return code change.
