      iwlwifi: mvm: BT Coex - fix a NULL pointer exception · 4cd4b50c
      Emmanuel Grumbach authored
      The commit below introduced an unsafe dereference of
      mvmvif->phy_ctxt. It can be NULL even if we hold the mutex.
      We can be handling a BT Coex notification while the vif has
      already been unassigned. This can happen since the BT Coex
      notification is hanled asynchronuously: we can have started
      to handle the BT Coex notification trying to acquire the
      mutex while the unassign flow already got it. The BT Coex
      notification handling will wait for the mutext. I'll get it
      later, but then mvmvif->phy_ctxt will be NULL.

       1) Missing netlink attribute validation in nft_lookup, from Patrick
          McHardy.
      
       2) Restrict ipv6 partial checksum handling to UDP, since that's the
          only case it works for.  From Vlad Yasevich.
      
       3) Clear out silly device table sentinal macros used by SSB and BCMA
          drivers.  From Joe Perches.
      
       4) Make sure the remote checksum code never creates a situation where
          the remote checksum is applied yet the tunneling metadata describing
          the remote checksum transformation is still present.  Otherwise an
          external entity might see this and apply the checksum again.  From
          Tom Herbert.
      
       5) Use msecs_to_jiffies() where applicable, from Nicholas Mc Guire.
      
       6) Don't explicitly initialize timer struct fields, use setup_timer()
          and mod_timer() instead.  From Vaishali Thakkar.
      
       7) Don't invoke tg3_halt() without the tp->lock held, from Jun'ichi
          Nomura.
      
       8) Missing __percpu annotation in ipvlan driver, from Eric Dumazet.
      
       9) Don't potentially perform skb_get() on shared skbs, also from Eric
          Dumazet.
      
      10) Fix COW'ing of metrics for non-DST_HOST routes in ipv6, from Martin
          KaFai Lau.
      
      11) Fix merge resolution error between the iov_iter changes in vhost and
          some bug fixes that occurred at the same time.  From Jason Wang.
      
      12) If rtnl_configure_link() fails we have to perform a call to
          ->dellink() before unregistering the device.  From WANG Cong.

      md/raid5: Fix livelock when array is both resyncing and degraded. · 26ac1073
      NeilBrown authored
      Commit a7854487:
        md: When RAID5 is dirty, force reconstruct-write instead of read-modify-write.
      
      Causes an RCW cycle to be forced even when the array is degraded.
      A degraded array cannot support RCW as that requires reading all data
      blocks, and one may be missing.
      
      Forcing an RCW when it is not possible causes a live-lock and the code
      spins, repeatedly deciding to do something that cannot succeed.
      
      So change the condition to only force RCW on non-degraded arrays.
