      [PATCH] rename get_lease to break_lease · 9de88958
      Matthew Wilcox authored
      Al pointed out that the current name of get_lease is extremely confusing
      and I agree.
      
      This (a) renames it to break_lease and (b) fixes a bug noticed by Dave
      Hansen which could cause a NULL pointer dereference under high load.

      driver model: exploit kobject contstructs. · b12cf4ff
      Patrick Mochel authored
      This makes the driver model core (for devices) exploit the kobject
      infrastructure more and make the resulting code quite a bit simpler. 
      
      For one, device_register() mimmicks kobject_register() in that it now only
      calls device_initialize() and device_add() back to back. Similarly, 
      device_unregister() calls device_del() and put_device() consecutively. 
      
      device_del() no longer removes and frees the device, it only removes them.
      It also removes the devices from the global and sibling lists. This was 
      previously done by device_put(), but moved here to be symmetrical with 
      device_add().
      
      The device's parent is now only incremented in device_add() and decremented
      in device_del(), fixing a bug in which the parent's refcount was incremented
      twice. 
      
      Because of these simplifications, the core can easily be converted to use 
      the kobject reference counting infrastructure. get_device() now simply 
      forwards the call to kobject_get() and ditto for put_device(). 
      device_release() is implemented to handle the freeing of devices once their
      reference count reaches 0.
      
      Since we're using the kobject refcounting model, we no longer need the 
      checking or setting of the device state field, so it has been removed. 
      The only users of it were the power routines. In those, it is implicit that
      we have a valid device, since we've already taken device_sem, and we're 
      walking the list (all modifications are protected by device_sem).
      
      struct device::lock, and the helpers to lock/unlock have been removed. No
      one has ever used them, and no one is likely to use them.

      [PATCH] remove duplicated assignment from sys_capget. · a879e2fd
      Chris Wright authored
      This removes the code from cap_sysget that fills out the capability set
      being returned to userspace.  The module handles this in a policy
      specific way.  This updates the dummy.c module to fill in return data
      according to superuser policy, and also disables setting capabilities in
      superuser policy.

      sysfs: do permission checking on open. · 0de8c962
      Patrick Mochel authored
      sysfs has always had a bug that would allow a read-only file to be opened 
      for writing. It has also returned 0 on write when there was no store method
      defined for the file. 
      
      This addresses both via sysfs_open_file(). It checks the flags the file was
      opened with and compares them with the mode of the inode. If the mode does
      not support the flags passed, -EPERM is returned.
      
      If the sysfs_ops for the object does not have the correct method for the 
      flags, -EACCESS is returned. 
      
      Since all checks happen on open(), the corresponding checks in the read()
      and write() methods have been removed.
