      MIPS: Fix sched_getaffinity with MT FPAFF enabled · 226302bd
      Felix Fietkau authored
      commit 1d62d737 upstream.
      
      p->thread.user_cpus_allowed is zero-initialized and is only filled on
      the first sched_setaffinity call.
      
      To avoid adding overhead in the task initialization codepath, simply OR
      the returned mask in sched_getaffinity with p->cpus_allowed.

      target: REPORT LUNS should return LUN 0 even for dynamic ACLs · 82371332
      Roland Dreier authored
      commit 9c395170 upstream.
      
      If an initiator doesn't have any real LUNs assigned, we should report
      LUN 0 and a LUN list length of 1.  Some versions of Solaris at least
      go beserk if we report a LUN list length of 0.

      md/raid1: extend spinlock to protect raid1_end_read_request against inconsistencies · 966b20a3
      NeilBrown authored
      commit 423f04d6 upstream.
      
      raid1_end_read_request() assumes that the In_sync bits are consistent
      with the ->degaded count.
      raid1_spare_active updates the In_sync bit before the ->degraded count
      and so exposes an inconsistency, as does error()
      So extend the spinlock in raid1_spare_active() and error() to hide those
      inconsistencies.
      
      This should probably be part of
        Commit: 34cab6f4 ("md/raid1: fix test for 'was read error from
        last working device'.")
      as it addresses the same issue.  It fixes the same bug and should go
      to -stable for same reasons.
      
      Fixes: 76073054 ("md/raid1: clean up read_balance.")

      target/iscsi: Fix double free of a TUR followed by a solicited NOPOUT · 1faeb78f
      Alexei Potashnik authored
      commit 9547308b upstream.
      
      Make sure all non-READ SCSI commands get targ_xfer_tag initialized
      to 0xffffffff, not just WRITEs.
      
      Double-free of a TUR cmd object occurs under the following scenario:
      
      1. TUR received (targ_xfer_tag is uninitialized and left at 0)
      2. TUR status sent
      3. First unsolicited NOPIN is sent to initiator (gets targ_xfer_tag of 0)
      4. NOPOUT for NOPIN (with TTT=0) arrives
       - its ExpStatSN acks TUR status, TUR is queued for removal
       - LIO tries to find NOPIN with TTT=0, but finds the same TUR instead,
         TUR is queued for removal for the 2nd time
      
      (Drop unbalanced conditional bracket usage - nab)

      USB: sierra: add 1199:68AB device ID · 6735cd0e
      Dirk Behme authored
      commit 74472233 upstream.
      
      Add support for the Sierra Wireless AR8550 device with
      USB descriptor 0x1199, 0x68AB.
      
      It is common with MC879x modules 1199:683c/683d which
      also are composite devices with 7 interfaces (0..6)
      and also MDM62xx based as the AR8550.
      
      The major difference are only the interface attributes
      02/02/01 on interfaces 3 and 4 on the AR8550. They are
      vendor specific ff/ff/ff on MC879x modules.

      crypto: ixp4xx - Remove bogus BUG_ON on scattered dst buffer · 1d9fd242
      Herbert Xu authored
      commit f898c522 upstream.
      
      This patch removes a bogus BUG_ON in the ablkcipher path that
      triggers when the destination buffer is different from the source
      buffer and is scattered.

      xen/gntdevt: Fix race condition in gntdev_release() · a9723364
      Marek Marczykowski-Górecki authored
      commit 30b03d05 upstream.
      
      While gntdev_release() is called the MMU notifier is still registered
      and can traverse priv->maps list even if no pages are mapped (which is
      the case -- gntdev_release() is called after all). But
      gntdev_release() will clear that list, so make sure that only one of
      those things happens at the same time.

      Unmapping may require sleeping and we unmap while holding priv->lock, so

      jbd2: protect all log tail updates with j_checkpoint_mutex · 7f63bfd0
      Jan Kara authored
      commit a78bb11d upstream.
      
      There are some log tail updates that are not protected by j_checkpoint_mutex.
      Some of these are harmless because they happen during startup or shutdown but
      updates in jbd2_journal_commit_transaction() and jbd2_journal_flush() can
      really race with other log tail updates (e.g. someone doing
      jbd2_journal_flush() with someone running jbd2_cleanup_journal_tail()). So
      protect all log tail updates with j_checkpoint_mutex.

      pktgen: Require CONFIG_INET due to use of IPv4 checksum function · 516aa86b
      Thomas Graf authored
      commit ffd756b3 upstream.
      
      Unlike for IPv6, the IPv4 checksum functions are only available
      if CONFIG_INET is set.

      ipv6: Fix build failure when CONFIG_INET disabled · a1a1e789
      Ben Hutchings authored
      output_core.c, added in 3.2.66, is only needed and can only be
      compiled when CONFIG_INET is enabled.
      
      The condition in the Makefile is already correct upstream.
