      [PATCH] dell_rbu: changes in packet update mechanism · ad6ce87e
      由 Abhay Salunke 提交于 
      In the current dell_rbu code ver 2.0 the packet update mechanism makes the
user app dump every individual packet in to the driver.

This adds in efficiency as every packet update makes the
/sys/class/firmware/dell_rbu/loading and data files to disappear and reappear
again.  Thus the user app needs to wait for the files to reappear to dump
another packet.  This slows down the packet update tremendously in case of
large number of packets.  I am submitting a new patch for dell_rbu which will
change the way we do packet updates;

In the new method the user app will create a new single file which has already
packetized the rbu image and all the packets are now staged in this file.

This driver also creates a new entry in
/sys/devices/platform/dell_rbu/packet_size ; the user needs to echo the packet
size here before downloading the packet file.

The user should do the following:

 create one single file which has all the packets stacked together.
 echo the packet size in to /sys/devices/platform/dell_rbu/packet_size.
 echo 1 > /sys/class/firmware/dell_rbu/loading
 cat the packetfile > /sys/class/firmware/dell_rbu/data
 echo 0 > /sys/class/firmware/dell_rbu/loading

The driver takes the file which came through /sys/class/firmware/dell_rbu/data
and takes chunks of paket_size data from it and place in contiguous memory.

This makes packet update process very efficient and fast.  As all the packet
update happens in one single operation.  The user can still read back the
downloaded file from /sys/devices/platform/dell_rbu/data.

      [PATCH] Keys: Add possessor permissions to keys [try #3] · 664cceb0
      由 David Howells 提交于 
      The attached patch adds extra permission grants to keys for the possessor of a
key in addition to the owner, group and other permissions bits. This makes
SUID binaries easier to support without going as far as labelling keys and key
targets using the LSM facilities.

This patch adds a second "pointer type" to key structures (struct key_ref *)
that can have the bottom bit of the address set to indicate the possession of
a key. This is propagated through searches from the keyring to the discovered
key. It has been made a separate type so that the compiler can spot attempts
to dereference a potentially incorrect pointer.

The "possession" attribute can't be attached to a key structure directly as
it's not an intrinsic property of a key.

Pointers to keys have been replaced with struct key_ref *'s wherever
possession information needs to be passed through.

This does assume that the bottom bit of the pointer will always be zero on
return from kmem_cache_alloc().

The key reference type has been made into a typedef so that at least it can be
located in the sources, even though it's basically a pointer to an undefined
type. I've also renamed the accessor functions to be more useful, and all
reference variables should now end in "_ref".
