Currently we check for permission before deleting entries from SAD and
SPD, (see security_xfrm_policy_delete() security_xfrm_state_delete())
However we are not checking for authorization when flushing the SPD and
the SAD completely. It was perhaps missed in the original security hooks
patch.
This patch adds a security check when flushing entries from the SAD and
SPD. It runs the entire database and checks each entry for a denial.
If the process attempting the flush is unable to remove all of the
entries a denial is logged the the flush function returns an error
without removing anything.
This is particularly useful when a process may need to create or delete
its own xfrm entries used for things like labeled networking but that
same process should not be able to delete other entries or flush the
entire database.

check_compat_entry_size_and_hooks iterates over the matches and calls
compat_check_calc_match, which loads the match and calculates the
compat offsets, but unlike the non-compat version, doesn't call
->checkentry yet. On error however it calls cleanup_matches, which in
turn calls ->destroy, which can result in crashes if the destroy
function (validly) expects to only get called after the checkentry
function.
Add a compat_release_match function that only drops the module reference
on error and rename compat_check_calc_match to compat_find_calc_match to
reflect the fact that it doesn't call the checkentry function.

Previously inet devices were only constructed when addresses are added
(or rarely in ipmr). Therefore the default config values they get are
the ones at the time of these operations.
Now that we're creating inet devices earlier, this changes the
behaviour of default config values in an incompatible way (see bug
#8519).
This patch creates a compromise by setting the default values at the
same point as before but only for those that have not been explicitly
set by the user since the inet device's creation.

Previously once inetdev_init has been called on a device any changes
made to ipv4_devconf_dflt would have no effect on that device's
configuration.
This creates a problem since we have moved the point where
inetdev_init is called from when an address is added to where the
device is registered.
This patch is the first half of a set that tries to mimic the old
behaviour while still calling inetdev_init.
It propagates any changes to ipv4_devconf_dflt to those devices that
have not had the corresponding attribute set.
The next patch will forcibly set all values at the point where
inetdev_init was previously called.

Several people have reported LITE-ON LTR-48246S detection failed
because SETXFER fails. It seems the device raises IRQ too early after
SETXFER. This is controller independent. The same problem has been
reported for different controllers.
So, now we have pata_via where the controller raises IRQ before it's
ready after SETXFER and a device which does similar thing. This patch
makes libata always execute SETXFER via polling. As this only happens
during EH, performance impact is nil. Setting ATA_TFLAG_POLLING is
also moved from issue hot path to ata_dev_set_xfermode() - the only
place where SETXFER can be issued.
Note that ATA_TFLAG_POLLING applies only to drivers which implement
SFF TF interface and use libata HSM. More advanced controllers ignore
the flag. This doesn't matter for this fix as SFF TF controllers are
the problematic ones.

we use the initiator tuple [[HWADDRESS | NETDEVNAME], INITIATOR_NAME] and

This patch adds the netdev name, which is used by software iscsi when
it binds a session to a netdevice using the SO_BINDTODEVICE sock opt.
It cannot use HWADDRESS because if someone did vlans then the same netdevice
will have the same mac and the initiator,target id will not be unique.

The cmdsn allocation and pdu transmit code can race, and we can end
up sending a pdu with cmdsn 10 before a pdu with 5. The target will
then fail the connection/session. This patch fixes the problem by
delaying the cmdsn allocation until we are about to send the pdu.
This also removes the xmitmutex. We were using the connection xmitmutex
during error handling to handle races with mtask and ctask cleanup and
completion. For ctasks we now have nice refcounting and for the mtask,
if we hit the case where the mtask timesout and it is floating
around somewhere in the driver, we end up dropping the session.
And to handle session level cleanup, we use the xmit suspend bit
along with scsi_flush_queue and the session lock to make sure
that the xmit thread is not possibly transmitting a task while
we are trying to kill it.

I think we have a subtle race on ppc64 with the tlb batching. The
common code expects tlb_flush() to actually flush any pending TLB
batch. It does that because it delays all page freeing until after
tlb_flush() is called, in order to ensure no stale reference to
those pages exist in any TLB, thus causing potential access to
the freed pages.
However, our tlb_flush only triggers the RCU for freeing page
table pages, it does not currently trigger a flush of a pending
TLB/hash batch, which is, I think, an error. This fixes it.
