      efi/fdt: Avoid FDT manipulation after ExitBootServices() · c8f325a5
      Ard Biesheuvel authored
      Some AArch64 UEFI implementations disable the MMU in ExitBootServices(),
      after which unaligned accesses to RAM are no longer supported.
      
      Commit:
      
        abfb7b68 ("efi/libstub/arm*: Pass latest memory map to the kernel")
      
      fixed an issue in the memory map handling of the stub FDT code, but
      inadvertently created an issue with such firmware, by moving some
      of the FDT manipulation to after the invocation of ExitBootServices().
      
      Given that the stub's libfdt implementation uses the ordinary, accelerated
      string functions, which rely on hardware handling of unaligned accesses,
      manipulating the FDT with the MMU off may result in alignment faults.
      
      So fix the situation by moving the update_fdt_memmap() call into the
      callback function invoked by efi_exit_boot_services() right before it
      calls the ExitBootServices() UEFI service (which is arguably a better
      place for it anyway)
      
      Note that disabling the MMU in ExitBootServices() is not compliant with
      the UEFI spec, and carries great risk due to the fact that switching from
      cached to uncached memory accesses halfway through compiler generated code
      (i.e., involving a stack) can never be done in a way that is architecturally
      safe.

          have masked the event from generating interrupts, doesn't mean the
          bit won't still be set in the interrupt status register. From Alexey

      syszkaller fuzzer was able to trigger a divide by zero, when
      TCP window scaling is not enabled.
      
      SO_RCVBUF can be used not only to increase sk_rcvbuf, also
      to decrease it below current receive buffers utilization.
      
      If mss is negative or 0, just return a zero TCP window.

      net/sched: matchall: Fix configuration race · fd62d9f5
      Yotam Gigi authored
      In the current version, the matchall internal state is split into two
      structs: cls_matchall_head and cls_matchall_filter. This makes little
      sense, as matchall instance supports only one filter, and there is no
      situation where one exists and the other does not. In addition, that led
      to some races when filter was deleted while packet was processed.
      
      Unify that two structs into one, thus simplifying the process of matchall
      creation and deletion. As a result, the new, delete and get callbacks have
      a dummy implementation where all the work is done in destroy and change
      callbacks, as was done in cls_cgroup.
