[v4,2/5] security: add pdcp short MAC-I support
Checks
Commit Message
From: Hemant Agrawal <hemant.agrawal@nxp.com>
This patch add support to handle PDCP short MAC-I domain
along with standard control and data domains as it has to
be treaty as special case with PDCP protocol offload support.
ShortMAC-I is the 16 least significant bits of calculated MAC-I. Usually
when a RRC message is exchanged between UE and eNodeB it is integrity &
ciphered protected.
MAC-I = f(key, varShortMAC-I, count, bearer, direction).
Here varShortMAC-I is prepared by using (current cellId, pci of source cell
and C-RNTI of old cell). Other parameters like count, bearer and
direction set to all 1.
