Paul Moore 609c92feea [NetLabel]: make the CIPSOv4 cache spinlocks bottom half safe
The CIPSOv4 cache traversal routines are triggered both the userspace events
(cache invalidation due to DOI removal or updated SELinux policy) and network
packet processing events.  As a result there is a problem with the existing
CIPSOv4 cache spinlocks as they are not bottom-half/softirq safe.  This patch
converts the CIPSOv4 cache spin_[un]lock() calls into spin_[un]lock_bh() calls
to address this problem.

Paul Moore 14a72f53fb [NetLabel]: correct improper handling of non-NetLabel peer contexts
Fix a problem where NetLabel would always set the value of 
sk_security_struct->peer_sid in selinux_netlbl_sock_graft() to the context of
the socket, causing problems when users would query the context of the
connection.  This patch fixes this so that the value in
sk_security_struct->peer_sid is only set when the connection is NetLabel based,
otherwise the value is untouched.

This has been discussed on dccp@vger and removes the necessity for applications
to supply service codes in each and every case.

If an application does not want to provide a service code, that's fine, it will

This patch has been tested using various client/server configurations
(including listening on multiple service codes).

The two function call API for creating a new RPC client is now obsolete.
Remove it.

Also, remove an unnecessary check to see whether the caller is capable of
using privileged network services.  The kernel RPC client always uses a
privileged ephemeral port by default; callers are responsible for checking
the authority of users to make use of any RPC service, or for specifying
that a nonprivileged port is acceptable.

messages.  To achieve this, check if the packet in forwarding patch is
NDP message.

With this patch, the proxy neighbor entries are always looked up in
forwarding path.  We may want to optimize further.

Based on MIPL2 kernel patch.

Patrick McHardy 4c5de695cf [NETFILTER]: PPTP conntrack: fix another GRE keymap leak
When the master PPTP connection times out while still having unfullfilled
expectations (and a GRE keymap entry) associated with it, the keymap entry
is not destroyed.

Add a destroy callback to struct ip_conntrack_helper and use it to destroy
PPTP siblings when the master is destroyed.

Patrick McHardy fd5e3befa4 [NETFILTER]: PPTP conntrack: fix GRE keymap leak
When destroying the GRE expectations without having seen the GRE connection
the keymap entry is not freed, leading to a memory leak and, in case of
a following call within the same session, failure during expectation setup.
