      net: add doc for in6_pton() · 28194fcd
      Amerigo Wang authored
      
      
      It is not easy to use in6_pton() correctly without reading
      its definition, so add some doc for it.

      tcp: resets are misrouted · 4c675258
      Alexey Kuznetsov authored
      After commit e2446eaa
      
       ("tcp_v4_send_reset: binding oif to iif in no
      sock case").. tcp resets are always lost, when routing is asymmetric.
      Yes, backing out that patch will result in misrouting of resets for
      dead connections which used interface binding when were alive, but we
      actually cannot do anything here.  What's died that's died and correct
      handling normal unbound connections is obviously a priority.
      
      Comment to comment:
      > This has few benefits:
      >   1. tcp_v6_send_reset already did that.
      
      It was done to route resets for IPv6 link local addresses. It was a
      mistake to do so for global addresses. The patch fixes this as well.
      
      Actually, the problem appears to be even more serious than guaranteed
      loss of resets.  As reported by Sergey Soloviev <sol@eqv.ru>, those
      misrouted resets create a lot of arp traffic and huge amount of
      unresolved arp entires putting down to knees NAT firewalls which use
      asymmetric routing.

      ====================
      Here is a batch of fixes intended for 3.7...
      
      Amitkumar Karwar provides a couple of mwifiex fixes to correctly
      report some reason codes for certain connection failures.  He also
      provides a fix to cleanup after a scanning failure.  Bing Zhao rounds
      that out with another mwifiex scanning fix.
      
      Daniel Golle gives us a fix for a copy/paste error in rt2x00.
      
      Felix Fietkau brings a couple of ath9k fixes related to suspend/resume,
      and a couple of fixes to prevent memory leaks in ath9k and mac80211.
      
      Ronald Wahl sends a carl9170 fix for a sleep in softirq context.
      
      Thomas Pedersen reorders some code to prevent drv_get_tsf from being
      called while holding a spinlock, now that it can sleep.
      
      Finally, Wei Yongjun prevents a NULL pointer dereference in the
      ath5k driver.
      
      Please let me know if there are problems!

      Pull pwm changes from Thierry Reding:
       "All legacy PWM providers have now been moved to the PWM subsystem.
        The plan for 3.8 is to adapt all board files to provide a lookup table
        for PWM devices in order to get rid of the global namespace.
        Subsequently, users of the legacy pwm_request() and pwm_free()
        functions can be migrated to the new pwm_get() and pwm_put()
        functions.  Once this has been completed, the legacy API and the
        compatibility code in the core can be removed.
      
        In addition to the above, these changes also add support for
        configuring the polarity of a PWM signal (currently only supported on
        ECAP and EHRPWM) and include a much needed rework of the i.MX driver.
        Managed functions to obtain and release a PWM device (devm_pwm_get()
        and devm_pwm_put()) have been added and the pwm-backlight driver has
        been updated to use them.  If the PWM subsystem hasn't been enabled,
        dummy functions are provided that allow the subsystem to safely
        compile out.
      
        Some common checks on input parameters have been moved to the core and
        removed from the drivers.  Finally, a small fix corrects the
        description of the PWM specifier's second cell in the device tree
        representation."

      Pull scsi target updates from Nicholas Bellinger:
       "Things have been calm for the most part with no new fabric drivers in
        flight for v3.7 (we're up to eight now !), so this update is primarily
        focused on addressing a few long-standing items within target-core and
        iscsi-target fabric code.
      
        The highlights include:
      
         - target: Simplify fabric sense data length handling (roland)
         - qla2xxx: Fix endianness of task management response code (roland)
         - target: fix truncation of mode data, support zero allocation length
           (paolo)
         - target: Properly support zero-length commands in normal processing
           path (paolo)
         - iscsi-target: Correctly set 0xffffffff field within ISCSI_OP_REJECT
           PDU (ronnie + nab)
         - iscsi-target: Add explicit set of cache_dynamic_acls=1 for TPG
           demo-mode (ronnie + nab)
         - target/file: Re-enable optional fd_buffered_io=1 operation (nab +
           hch)
         - iscsi-target: Add MaxXmitDataSegmenthLength forr target ->
           initiator MDRSL declaration (nab)
         - target: Add target_submit_cmd_map_sgls for SGL fabric memory
           passthrough (nab + hch)
         - tcm_loop: Convert I/O path to use target_submit_cmd_map_sgls (hch +
           nab)
         - tcm_vhost: Convert I/O path to use target_submit_cmd_map_sgls (nab
           + hch)
      
        The last series for adding a new target_submit_cmd_map_sgls() fabric
        caller (as requested by hch) that accepts pre-allocated SGL memory
        (using existing logic), along with converting tcm_loop + tcm_vhost has
        only been in -next for the last days, but has gotten enough review
        +testing and is clear enough a mechanical change that I think it's
        reasonable to merge for -rc1 code.
      
        Thanks again to everyone who contributed this round! Extra special
        thanks to Roland (PureStorage) for tracking down the qla2xxx target
        TMR response code endian issue, and to Paolo (Redhat) for resolving
        the long standing zero-length CDB issues within target-core between
        virtual and pSCSI backends."
