      um: virtio: Keep reading on -EAGAIN · 7e607460
      Johannes Berg authored
      When we get an interrupt from the socket getting readable,
      and start reading, there's a possibility for a race. This
      depends on the implementation of the device, but e.g. with
      qemu's libvhost-user, we can see:
      
       device                 virtio_uml
      ---------------------------------------
        write header
                               get interrupt
                               read header
                               read body -> returns -EAGAIN
        write body
      
      The -EAGAIN return is because the socket is non-blocking,
      and then this leads us to abandon this message.
      
      In fact, we've already read the header, so when the get
      another signal/interrupt for the body, we again read it
      as though it's a new message header, and also abandon it
      for the same reason (wrong size etc.)
      
      This essentially breaks things, and if that message was
      one that required a response, it leads to a deadlock as
      the device is waiting for the response but we'll never
      reply.
      
      Fix this by spinning on -EAGAIN as well when we read the
      message body. We need to handle -EAGAIN as "no message"
      while reading the header, since we share an interrupt.
      
      Note that this situation is highly unlikely to occur in
      normal usage, since there will be very few messages and
      only in the startup phase. With the inband call feature
      this does tend to happen (eventually) though.

      um: Don't trace irqflags during shutdown · 5c1f33e2
      Johannes Berg authored
      In the main() code, we eventually enable signals just before
      exec() or exit(), in order to to not have signals pending and
      delivered *after* the exec().
      
      I've observed SIGSEGV loops at this point, and the reason seems
      to be the irqflags tracing; this makes sense as the kernel is
      no longer really functional at this point. Since there's really
      no reason to use unblock_signals_trace() here (I had just done
      a global search & replace), use the plain unblock_signals() in
      this case to avoid going into the no longer functional kernel.

      gfs2: Fix initialisation of args for remount · d5798141
      Andrew Price authored
      When gfs2 was converted to use fs_context, the initialisation of the
      mount args structure to the currently active args was lost with the
      removal of gfs2_remount_fs(), so the checks of the new args on remount
      became checks against the default values instead of the current ones.
      This caused unexpected remount behaviour and test failures (xfstests
      generic/294, generic/306 and generic/452).
      
      Reinstate the args initialisation, this time in gfs2_init_fs_context()
      and conditional upon fc->purpose, as that's the only time we get control
      before the mount args are parsed in the remount process.

      This cures a panic on restart after a kexec operation on 5.3 and 5.4
      kernels.
      
      The underlying state of the iommu registers (iommu->flags &
      VTD_FLAG_TRANS_PRE_ENABLED) on a restart results in a domain being marked as
      "DEFER_DEVICE_DOMAIN_INFO" that produces an Oops in identity_mapping().

      virtio_ring: fix stalls for packed rings · 40ce7919
      Marvin Liu authored
      When VIRTIO_F_RING_EVENT_IDX is negotiated, virtio devices can
      use virtqueue_enable_cb_delayed_packed to reduce the number of device
      interrupts.  At the moment, this is the case for virtio-net when the
      napi_tx module parameter is set to false.
      
      In this case, the virtio driver selects an event offset and expects that
      the device will send a notification when rolling over the event offset
      in the ring.  However, if this roll-over happens before the event
      suppression structure update, the notification won't be sent. To address
      this race condition the driver needs to check wether the device rolled
      over the offset after updating the event suppression structure.
      
      With VIRTIO_F_RING_PACKED, the virtio driver did this by reading the
      flags field of the descriptor at the specified offset.
      
      Unfortunately, checking at the event offset isn't reliable: if
      descriptors are chained (e.g. when INDIRECT is off) not all descriptors
      are overwritten by the device, so it's possible that the device skipped
      the specific descriptor driver is checking when writing out used
      descriptors. If this happens, the driver won't detect the race condition
      and will incorrectly expect the device to send a notification.
      
      For virtio-net, the result will be a TX queue stall, with the
      transmission getting blocked forever.
      
      With the packed ring, it isn't easy to find a location which is
      guaranteed to change upon the roll-over, except the next device
      descriptor, as described in the spec:
      
              Writes of device and driver descriptors can generally be
              reordered, but each side (driver and device) are only required to
              poll (or test) a single location in memory: the next device descriptor after
              the one they processed previously, in circular order.
      
      while this might be sub-optimal, let's do exactly this for now.
