      Input: adxl34x - do not treat FIFO_MODE() as boolean · 1dbc080c
      Arnd Bergmann authored
      FIFO_MODE() is a macro expression with a '<<' operator, which gcc points
      out could be misread as a '<':
      
      drivers/input/misc/adxl34x.c: In function 'adxl34x_probe':
      drivers/input/misc/adxl34x.c:799:36: error: '<<' in boolean context, did you mean '<' ? [-Werror=int-in-bool-context]
      
      While utility of this warning is being disputed (Chief Penguin: "This
      warning is clearly pure garbage.") FIFO_MODE() extracts range of values,
      with 0 being FIFO_BYPASS, and not something that is logically boolean.
      
      This converts the test to an explicit comparison with FIFO_BYPASS,
      making it clearer to gcc and the reader what is intended.

      epoll: fix race between ep_poll_callback(POLLFREE) and ep_free()/ep_remove() · 138e4ad6
      Oleg Nesterov authored
      The race was introduced by me in commit 971316f0 ("epoll:
      ep_unregister_pollwait() can use the freed pwq->whead").  I did not
      realize that nothing can protect eventpoll after ep_poll_callback() sets
      ->whead = NULL, only whead->lock can save us from the race with
      ep_free() or ep_remove().
      
      Move ->whead = NULL to the end of ep_poll_callback() and add the
      necessary barriers.
      
      TODO: cleanup the ewake/EPOLLEXCLUSIVE logic, it was confusing even
      before this patch.
      
      Hopefully this explains use-after-free reported by syzcaller:

      bridge: switchdev: Clear forward mark when transmitting packet · 79e99bdd
      Ido Schimmel authored
      Commit 6bc506b4 ("bridge: switchdev: Add forward mark support for
      stacked devices") added the 'offload_fwd_mark' bit to the skb in order
      to allow drivers to indicate to the bridge driver that they already
      forwarded the packet in L2.
      
      In case the bit is set, before transmitting the packet from each port,
      the port's mark is compared with the mark stored in the skb's control
      block. If both marks are equal, we know the packet arrived from a switch
      device that already forwarded the packet and it's not re-transmitted.
      
      However, if the packet is transmitted from the bridge device itself
      (e.g., br0), we should clear the 'offload_fwd_mark' bit as the mark
      stored in the skb's control block isn't valid.
      
      This scenario can happen in rare cases where a packet was trapped during
      L3 forwarding and forwarded by the kernel to a bridge device.

      mlxsw: spectrum: Forbid linking to devices that have uppers · 25cc72a3
      Ido Schimmel authored
      The mlxsw driver relies on NETDEV_CHANGEUPPER events to configure the
      device in case a port is enslaved to a master netdev such as bridge or
      bond.
      
      Since the driver ignores events unrelated to its ports and their
      uppers, it's possible to engineer situations in which the device's data
      path differs from the kernel's.
      
      One example to such a situation is when a port is enslaved to a bond
      that is already enslaved to a bridge. When the bond was enslaved the
      driver ignored the event - as the bond wasn't one of its uppers - and
      therefore a bridge port instance isn't created in the device.
      
      Until such configurations are supported forbid them by checking that the
      upper device doesn't have uppers of its own.

      When mounting to older servers, such as Windows XP (or even Windows 7),
      the limited error messages that can be passed back to user space can
      get confusing since the default dialect has changed from SMB1 (CIFS) to
      more secure SMB3 dialect. Log additional information when the user chooses
      to use the default dialects and when the server does not support the
