2018-12-11Add IPSec interface FIB index for TX packetPierre Pfister6-6/+36
This patch adds a configuration parameter to IPSec tunnels, enabling custom FIB selection for encapsulated packets. Although this option could also be used for policy-based IPSec, this change only enables it for virtual-tunnel-interface mode. Note that this patch does change the API default behavior regarding TX fib selection for encapsulated packets. Previous behavior was to use the same FIB after and before encap. The new default behavior consists in using the FIB 0 as default. Change-Id: I5c212af909940a8cf6c7e3971bdc7623a2296452 Signed-off-by: Pierre Pfister <ppfister@cisco.com>

2018-12-05Improve strncpy_s src/dst overlap checkDave Barach1-2/+12
Let m = user estimate of the (max) src string length, low = smaller address of (src, dst), hi = larger address (src, dst). if (low + (m - 1) >= hi), we have a *potential* overlapping copy which is not allowed. Before we declare overlap - and return an error - retry the check with m = actual src string length. The resulting "test string" failure affected aarch64 (only) because of differences in test code stack variable placement / alignment.
