parisc: sys_hpux: NUL terminator is one past the end

We allocate "len" number of chars so we should put the NUL at "len - 1"
to avoid corrupting memory.  Btw, strlen_user() is different from the
normal strlen() function because it includes NUL terminator in the
count.

FS-Cache: Reduce cookie ref count if submit fails.

I've been seeing issues with disposing cookies under vma pressure. The symptom
is that the refcount gets out of sync. In this case we fail to decrement the

ipvs: fix ipv6 hook registration for local replies

commit fc604767613b6d2036cdc35b660bc39451040a47
("ipvs: changes for local real server") from 2.6.37
introduced DNAT support to local real server but the
IPv6 LOCAL_OUT handler ip_vs_local_reply6() is
registered incorrectly as IPv4 hook causing any outgoing
IPv4 traffic to be dropped depending on the IP header values.

Chris tracked down the problem to CONFIG_IP_VS_IPV6=y

If the callee SID is bounded by the caller SID, then allowing

therefore safely allow the transition to occur.  Add this exemption
for both the case where a transition was explicitly requested by the
application and the case where an automatic transition is defined in

Smack: Bring-up access mode

People keep asking me for permissive mode, and I keep saying "no".

Permissive mode is wrong for more reasons than I can enumerate,
but the compelling one is that it's once on, never off.

Nonetheless, there is an argument to be made for running a
process with lots of permissions, logging which are required,
and then locking the process down. There wasn't a way to do
that with Smack, but this provides it.

The notion is that you start out by giving the process an
appropriate Smack label, such as "ATBirds". You create rules
with a wide range of access and the "b" mode. On Tizen it
might be:

	ATBirds	System	rwxalb
	ATBirds	User	rwxalb
	ATBirds	_	rwxalb
	User	ATBirds	wb
	System	ATBirds	wb

Accesses that fail will generate audit records. Accesses
that succeed because of rules marked with a "b" generate
log messages identifying the rule, the program and as much
object information as is convenient.

When the system is properly configured and the programs
brought in line with the labeling scheme the "b" mode can
be removed from the rules. When the system is ready for
production the facility can be configured out.

This provides the developer the convenience of permissive
mode without creating a system that looks like it is
enforcing a policy while it is not.

Smack used to use a mix of smack_known struct and char* throughout its
