2020-03-03geneve gtpu vxlan vxlan-gpe: VRF-aware bypass nodeNick Zavaritsky1-2/+2
Bypass node MUST NOT intercept a packet if destination IP doesn’t match a local address. However IP address interpretation depends on the VRF, hence bypass node must take that into account. This patch also factors-out common VTEP management and checking code.

2019-11-26fib: reduce save_rewrite_length to u8Klement Sekera1-1/+1
This is a preparation step for migrating NAT to use SVR (shallow virtual reassembly) to conserve space in vnet_buffer. Since max rewrite length is currently pre-data size (128), u8 is sufficient to hold that value.

2018-10-05vxlan:ip4 decap:remove access to tunnel objectEyal Bari1-0/+18
store local/remote addresses + vrf + vni in hash key store complete decap info in hash value (sw_if_index + next_index + error) this removes the need to access the tunnel object when matching both unicast and mcast. however for mcast handling it requires 3 hash lookups: * one failed unicast lookup (by src+dst addrs) * lookup by mcast(dst) addr . * unicast lookup (tunnel local ip as dst + pkt's src addr) where previously it needed 2: * lookup by src to find unicast tunnel + compare dst to local addr (failing for mcast) * lookup by mcast to find the mcast tunnel Change-Id: I7a3485d130a54194b8f7e2df0431258db36eceeb Signed-off-by: Eyal Bari <ebari@cisco.com>

2018-05-04Harmonize vec/pool_get_aligned object sizes and alignment requestsDave Barach1-0/+3
Object sizes must evenly divide alignment requests, or vice versa. Otherwise, only the first object will be aligned as requested. Three choices: add CLIB_CACHE_LINE_ALIGN_MARK(align_me) at the end of structures, manually pad to an even divisor or multiple of the alignment request, or use plain vectors/pools. static assert for enforcement.

2017-10-24Add extern to *_main global variable declarations in header files.Dave Wallace1-1/+1
- Global variables declared in header files without the use of the 'extern' keword will result in multiple instances of the variable to be created by the compiler -- one for each different source file in which the the header file is included. This results in wasted memory allocated in the BSS segments as well as potentially introducing bugs in the application.

2017-01-31Add vxlan-bypass feature to IP6 forwarding pathJohn Lo1-0/+2
Add vxlan-bypass feature which can be enabled on the IP6 underlay interface which receive VXLAN packets to accelerate VXLAN decap processing. The CLI to enable/disable it is: set interface ip6 vxlan-bypass <interface> [del] The vxlan-bypass feature is already supported on the IP4 underlay interface. The CLI to enable/disable it is: set interface ip vxlan-bypass <interface> [del] Move vxlan-bypass API/CLI support code from decap.c to vxlan.c. Also fixed two issues in the VXLAN decap path in the vxlan-input node: 1. Add verification of VXLAN packet FIB index with the encap-vrf-id of the VXLAN tunnel. 2. Fix checking of VXLANoIPv6 packet mcast DIP against that of the IP6 mcast VXLAN tunnel. Change-Id: I2bad4074a468c48fbb8bb5ac64f6437190756ed2 Signed-off-by: John Lo <loj@cisco.com>
