      fibmap: Warn and return an error in case of block > INT_MAX · b75dfde1
      Ritesh Harjani authored
      We better warn the fibmap user and not return a truncated and therefore
      an incorrect block map address if the bmap() returned block address
      is greater than INT_MAX (since user supplied integer pointer).
      
      It's better to pr_warn() all user of ioctl_fibmap() and return a proper
      error code rather than silently letting a FS corruption happen if the
      user tries to fiddle around with the returned block map address.
      
      We fix this by returning an error code of -ERANGE and returning 0 as the
      block mapping address in case if it is > INT_MAX.
      
      Now iomap_bmap() could be called from either of these two paths.
      Either when a user is calling an ioctl_fibmap() interface to get
      the block mapping address or by some filesystem via use of bmap()
      internal kernel API.
      bmap() kernel API is well equipped with handling of u64 addresses.
      
      WARN condition in iomap_bmap_actor() was mainly added to warn all
      the fibmap users. But now that we have directly added this warning
      for all fibmap users and also made sure to return 0 as block map address
      in case if addr > INT_MAX.
      So we can now remove this logic from iomap_bmap_actor().

      firmware_loader: revert removal of the fw_fallback_config export · 5a357703
      Luis Chamberlain authored
      Christoph's patch removed two unsused exported symbols, however, one
      symbol is used by the firmware_loader itself.  If CONFIG_FW_LOADER=m so
      the firmware_loader is modular but CONFIG_FW_LOADER_USER_HELPER=y we fail
      the build at mostpost.
      
      ERROR: modpost: "fw_fallback_config" [drivers/base/firmware_loader/firmware_class.ko] undefined!
      
      This happens because the variable fw_fallback_config is built into the
      kernel if CONFIG_FW_LOADER_USER_HELPER=y always, so we need to grant
      access to the firmware loader module by exporting it.
      
      Revert only one hunk from his patch.
