SELinux: Add a network node caching mechanism similar to the sel_netif_*() functions This patch adds a SELinux IP address/node SID caching mechanism similar to the sel_netif_*() functions. The node SID queries in the SELinux hooks files are also modified to take advantage of this new functionality. In addition, remove the address length information from the sk_buff parsing routines as it is redundant since we already have the address family.

/*
* Network node table
*
* SELinux must keep a mapping of network nodes to labels/SIDs. This
* mapping is maintained as part of the normal policy but a fast cache is
* needed to reduce the lookup overhead since most of these queries happen on
* a per-packet basis.

doc: Update the email address for Paul Moore in various source files My @hp.com will no longer be valid starting August 5, 2011 so an update is necessary. My new email address is employer independent so we don't have to worry about doing this again any time soon.

selinux: reduce the number of calls to synchronize_net() when flushing caches When flushing the AVC, such as during a policy load, the various network caches are also flushed, with each making a call to synchronize_net() which has shown to be expensive in some cases. This patch consolidates the network cache flushes into a single AVC callback which only calls synchronize_net() once for each AVC cache flush.
