      iwlwifi: mvm: rs: clear per rate stats when aggregation changes · b804eeb6
      Eyal Shapira authored
      
      
      The per rate stats should be cleared when aggregation state changes
      to avoid making rate scale decisions based on throughput figures which
      were collected prior to the aggregation state change and are now stale.
      While at it make sure any clearing of the per rate stats will get logged.

      iwlwifi: mvm: rs: fallback to legacy Tx columns · fd7dbee5
      Eyal Shapira authored
      
      
      Allow switching back to legacy Tx columns so we'll stop doing
      HT/VHT in case we're far from the AP. Stop active aggregation when
      making a deciding to stay in a legacy column.
      Despite having low legacy rates in the LQ table lower entries
      it doesn't help much in case we're doing aggregations as the
      aggregation was being transmitted in the initial rate of the table.
      
      This should help traffic stalls when far from the AP.

      iwlwifi: mvm: rs: reinit rs if no tx for a long time · 87d5e415
      Eyal Shapira authored
      
      
      After being idle for a long time (>5sec) the rs statistics
      will be stale so we prefer to reset rs and start from legacy
      rates again. This gives better results when the attenuation
      increased signficantly (e.g. we got further from the AP) and
      after a while we start Tx
      Note that the first Tx after the idle period will still go out
      in the old modulation and rate but this seemed a simpler approach
      compared to adding a timer or modifying mac80211 for this.
      The negative impact is negligble as we'll recover quickly.

      iwlwifi: mvm: rs: fix and cleanup rs_get_rate_action · e53839eb
      Eyal Shapira authored
      
      
      Change the down/upscale decision logic a bit to be based
      on different success ratio thresholds. This fixes the implementation
      compared to the rate scale algorithm which was planned to yield
      optimal results. Also fix a case where a lower rate wasn't explored
      despite being a potential for better throughput.
      While at it rewrite rs_get_rate_action to be more clear and clean.

      iwlwifi: mvm: delay enabling smart FIFO until after beacon RX · 0229cdaf
      Johannes Berg authored
      If we have no beacon data before association, delay smart FIFO
      enablement until after we have this data.
      
      Not doing so can cause association failures in extremely silent
      environments (usually only a shielded box/room) as beacon RX is
      not sent to the host immediately, and then the association time
      event ends without the host receiving any beacon even though it
      was on the air - it's just stuck on the FIFO.

      sym53c8xx_2: Set DID_REQUEUE return code when aborting squeue · fd1232b2
      Mikulas Patocka authored
      
      
      This patch fixes I/O errors with the sym53c8xx_2 driver when the disk
      returns QUEUE FULL status.
      
      When the controller encounters an error (including QUEUE FULL or BUSY
      status), it aborts all not yet submitted requests in the function
      sym_dequeue_from_squeue.
      
      This function aborts them with DID_SOFT_ERROR.
      
      If the disk has full tag queue, the request that caused the overflow is
      aborted with QUEUE FULL status (and the scsi midlayer properly retries
      it until it is accepted by the disk), but the sym53c8xx_2 driver aborts
      the following requests with DID_SOFT_ERROR --- for them, the midlayer
      does just a few retries and then signals the error up to sd.
      
      The result is that disk returning QUEUE FULL causes request failures.
      
      The error was reproduced on 53c895 with COMPAQ BD03685A24 disk
      (rebranded ST336607LC) with command queue 48 or 64 tags.  The disk has
      64 tags, but under some access patterns it return QUEUE FULL when there
      are less than 64 pending tags.  The SCSI specification allows returning
      QUEUE FULL anytime and it is up to the host to retry.

      powerpc: Don't try to set LPCR unless we're in hypervisor mode · 18aa0da3
      Paul Mackerras authored
      Commit 8f619b54
      
       ("powerpc/ppc64: Do not turn AIL (reloc-on
      interrupts) too early") added code to set the AIL bit in the LPCR
      without checking whether the kernel is running in hypervisor mode.  The
      result is that when the kernel is running as a guest (i.e., under
      PowerKVM or PowerVM), the processor takes a privileged instruction
      interrupt at that point, causing a panic.  The visible result is that
      the kernel hangs after printing "returning from prom_init".
      
      This fixes it by checking for hypervisor mode being available before
      setting LPCR.  If we are not in hypervisor mode, we enable relocation-on
      interrupts later in pSeries_setup_arch using the H_SET_MODE hcall.

       ("futex: avoid race between requeue and

      One was a late fix and the other a consequence of overlooking the whole
      requeuing logic.
      
      The first change caused our documentation to be incorrect, and the
      second made us aware that we need to explicitly add more details to it.

       4) If VLAN untagging fails, we double free the SKB in the bridging
          output path.  From Toshiaki Makita.
      
       5) Several call sites of sk->sk_data_ready() were referencing an SKB
          just added to the socket receive queue in order to calculate the
          second argument via skb->len.  This is dangerous because the moment
          the skb is added to the receive queue it can be consumed in another
          context and freed up.
      
          It turns out also that none of the sk->sk_data_ready()
          implementations even care about this second argument.
      
          So just kill it off and thus fix all these use-after-free bugs as a

      where the reason is that <linux/ceph_debug.h> is included much too late
      for the "pr_fmt()" define.
      
      The include of <linux/ceph_debug.h> needs to be the first include in the
      file, but fs/ceph/ioctl.c had for some reason missed that, and it wasn't
      noticeable until some unrelated header file changes brought in an
      indirect earlier include of <linux/kernel.h>.

      ====================
      tunnels: don't allow to add the same tunnel twice
      
      This series fixes the check of an existing tunnel with the same
      parameters when a new tunnel is added.  I've checked all users of
      ip_tunnel_newlink(): gre, gretap, ipip and vti. The bug exists only
      for gre and vti.

      vti: don't allow to add the same tunnel twice · 8d89dcdf
      Nicolas Dichtel authored
      Before the patch, it was possible to add two times the same tunnel:
      ip l a vti1 type vti remote 10.16.0.121 local 10.16.0.249 key 41
      ip l a vti2 type vti remote 10.16.0.121 local 10.16.0.249 key 41
      
      It was possible, because ip_tunnel_newlink() calls ip_tunnel_find() with the
      argument dev->type, which was set only later (when calling ndo_init handler
      in register_netdevice()). Let's set this type in the setup handler, which is
      called before newlink handler.
      
      Introduced by commit b9959fd3
      
       ("vti: switch to new ip tunnel code").
