2019-07-09gbp: Ownership of dynamically created vxlan-gbp tunnels managed via gbp_itfNeale Ranns1-1/+1
Type: fix This solves the ownership of vxlan-gbp tunnels. When the last reference of these goes away they need to be deleted. Currently there are two owners; gbp_itf via gef_itf and the lock held by the gbp_endpoint_location_t. The problem is that the loc removes its reference whilst the fwd still holds the gbp_itf, and things go wrong. This change moves the lifecycle management of the vxlan-gbp tunnel to the gbp_itf. When the last lock of the gbp_itf goes, so does the tunnel. now both the EP's loc and fwd can hold a lock on the gbp_itf and it's only removed when required. The other change is the management of the 'user' of the gbp_itf. Since each user can enable and disable different features, it's the job of the gbp_itf to apply the combined set. determining a unique 'uesr' from the caller was near impossible, so I moved that to the gbp_itf, and return the allocated user, hence the 'handle' that encodes both user and interface. The hash table maps from sw_if_index to pool index. Change-Id: I4c7bf4c0e5dcf33d1c545f262365e69151febcf4 Signed-off-by: Neale Ranns <nranns@cisco.com>

2019-07-02gbp: add anonymous l3-out external interfacesBenoît Ganne1-0/+3
So far, GBP l3-out packets classification & policy relied on programmed EP. All traffic to/from l3-out must go through a known EP. This patch introduces a new feature where l3-out next-hops are only known by their subnets (l3-out prefixes). As there are no longer known EPs to program, an interface must be configured as external anonymous l3-out. Packets classification & policy on this interface will rely on the external subnets programmed in the BD VRF. Note that contrary to all other interfaces in a GBP BD, external anonymous l3-out interfaces have BD L2 learning turned on and rely on ARP/ND.
