[PATCH] Keys: Add possessor permissions to keys [try #3]

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".

[PATCH] device-mapper: Fix queue_if_no_path initialisation

When creating a multipath device, if the queue_if_no_path parameter is
specified it gets ignored.

While the queue_if_no_path variable is correctly set to 1, the

live (resumed), the saved value (0) always overwrites the live value (1) so
the option *always* gets turned off.

The fix adds a parameter to the queue_if_no_path() function to indicate
whether the previous value should be preserved or not - if not, as when the
device is being set up, the saved value is set to the new value (1).

with open() on mqueue fs it is ok of course).  According to the
specification this a bug.  This trivial patch fixes this.

Fix interrupt test handler by adding check for IRQ assertion in
PCI_STATE register in addition to the status block updated bit.

Add test for valid ethernet address in tg3_set_mac_addr().

Add tg3_bus_string() to setup the PCI bus speed/width string for all
PCI/PCIX/PCI Express devices. This is used to print the bus type
during init_one().

19 years ago[TG3]: 5780 PHY fixes
Michael Chan [Tue, 27 Sep 2005 19:12:42 +0000 (12:12 -0700)]
[TG3]: 5780 PHY fixes

Fix 5780 PHY related problems:

1. MAC_RX_MODE reset must be done before setting up the MAC_MODE
   register on 5705_PLUS chips or the chip will stop receiving after
   a while. The MAC_RX_MODE reset is needed to prevent intermittently
   losing the first receive packet on serdes chips.

2. Skip MAC loopback test on 5780 because of hardware errata. Normal
   traffic including PHY loopback is not affected by the errata.

3. PHY loopback fails intermittently on 5708S and this is fixed by
   putting the PHY in loopback mode first before programming the MAC
   mode register. A MAC_RX_MODE reset is also added.

4. Return -EINVAL in tg3_nway_reset() if device is in TBI mode. Allow
   nway_reset if 5780S is in parallel detect mode.

5. Add missing PHY IDs in KNOWN_PHY_ID() macro.
