2016-07-25macsec: limit ICV length to 16 octetsDavide Caratti1-0/+2
IEEE 802.1AE-2006 standard recommends that the ICV element in a MACsec frame should not exceed 16 octets: add MACSEC_STD_ICV_LEN in uapi definitions accordingly, and avoid accepting configurations where the ICV length exceeds the standard value. Leave definition of MACSEC_MAX_ICV_LEN unchanged for backwards compatibility with userspace programs.

In netdevice.h we removed the structure in net-next that is being changes in 'net'. In macsec.c and rtnetlink.c we have overlaps between fixes in 'net' and the u64 attribute changes in 'net-next'. The mlx5 conflicts have to do with vxlan support dependencies. Signed-off-by: David S. Miller <davem@davemloft.net>
2016-05-09macsec: key identifier is 128 bits, not 64Sabrina Dubroca1-1/+3
The MACsec standard mentions a key identifier for each key, but doesn't specify anything about it, so I arbitrarily chose 64 bits. IEEE 802.1X-2010 specifies MKA (MACsec Key Agreement), and defines the key identifier to be 128 bits (96 bits "member identifier" + 32 bits "key number").

Minor overlapping changes in the conflicts. In the macsec case, the change of the default ID macro name overlapped with the 64-bit netlink attribute alignment fixes in net-next. Signed-off-by: David S. Miller <davem@davemloft.net>
