2021-02-25ipsec: enable input features on tunnelsBrian Russell4-30/+93
Make the ipsec[46]-tun-input nodes siblings of device-input so that input features can be enabled on them. Register ipsec-tun for feature updates. When a feature is enabled on the device-input arc and the ifindex is an IPSec tunnel, change the end node of the arc for that ifindex to be the appropriate ESP decrypt node. Set a flag on the tunnel to indicate that the feature arc should be started for packets input on the tunnel. Test input policing on ESP IPSec tunnels.

The move from ip4(6)_src_address_for_packet to fib_sas4(6)_get changed the behavior, so that the new looked only to adjacent gleans. This caused a problem for destinations routed according to FIB table.

2021-02-15vlib: refactor checksum offload supportMohsin Kazmi25-223/+332
Type: refactor This patch refactors the offload flags in vlib_buffer_t. There are two main reasons behind this refactoring. First, offload flags are insufficient to represent outer and inner headers offloads. Second, room for these flags in first cacheline of vlib_buffer_t is also limited. This patch introduces a generic offload flag in first cacheline. And detailed offload flags in 2nd cacheline of the structure for performance optimization.

2021-02-09l2: crash on l2_input_is_xconnectSteven Luong1-10/+8
Running vpp without any interface configured and then invoking the binary-api l2_xconnect_dump causes vpp to crash in l2_input_is_xconnect due to l2input_main.configs has no memory allocated to it, not even for the local interface which exists all the times. The reason that l2input_main.configs has no memory allocated to it was due to gerrit patch 29232 which took out a line in l2input_init /* Create the config vector */ vec_validate (mp->configs, 100); The fix is to iterate through l2input_main.configs for each interface in l2 to call l2_input_is_xconnect when dumping l2_xconnect interfaces.
