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.

|
|
* 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.
