2018-12-24tcp: compute seq_end in tcp_inputFlorin Coras3-50/+41
syn/fin are no longer added to seq_end so they must be considered individually in each state. Change-Id: I5e3047194101c4fca2db9f9ad29a4a6468c397ab Signed-off-by: Florin Coras <fcoras@cisco.com>

2018-12-22tapv2: coverity woeSteven1-2/+4
coverity complains about fd leaking inside the if statement because there is a goto which bypasses the statement close (fd). The fix is to close (fd) immediately after it is no longer used. Change-Id: Ic5035b07ec1f179ff3db77744843e47aa8067a3c Signed-off-by: Steven <sluong@cisco.com>
2018-12-21http server: improvementsFlorin Coras3-109/+291
- use http sessions to track communication with peer (as opposed to using the raw sessions) - for static server send ok message prior to sending data - static server can now handle GET requests spread over multiple packets.

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>
