2019-07-09gbp: Ownership of dynamically created vxlan-gbp tunnels managed via gbp_itfNeale Ranns1-140/+88
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>
2019-05-16init / exit function orderingDave Barach1-8/+7
The vlib init function subsystem now supports a mix of procedural and formally-specified ordering constraints. We should eliminate procedural knowledge wherever possible. The following schemes are *roughly* equivalent: static clib_error_t *init_runs_first (vlib_main_t *vm) { clib_error_t *error; ... do some stuff... if ((error = vlib_call_init_function (init_runs_next))) return error; ... } VLIB_INIT_FUNCTION (init_runs_first); and static clib_error_t *init_runs_first (vlib_main_t *vm) { ... do some stuff... } VLIB_INIT_FUNCTION (init_runs_first) = { .runs_before = VLIB_INITS("init_runs_next"), }; The first form will [most likely] call "init_runs_next" on the spot. The second form means that "init_runs_first" runs before "init_runs_next," possibly much earlier in the sequence. Please DO NOT construct sets of init functions where A before B actually means A *right before* B. It's not necessary - simply combine A and B - and it leads to hugely annoying debugging exercises when trying to switch from ad-hoc procedural ordering constraints to formal ordering constraints.

2019-03-28Punt InfraNeale Ranns1-19/+19
A punt/exception path that provides: 1) clients that use the infra 2) clients can create punt reasons 3) clients can register to recieve packets that are punted for a given reason to be sent to the desired node. 4) nodes which punt packets fill in the {reason,protocol} of the buffere (in the meta-data) and send to the new node "punt-dispatch" 5) punt-dispatch sends packets to the registered nodes or drops Change-Id: Ia4f144337f1387cbe585b4f375d0842aefffcde5 Signed-off-by: Neale Ranns <nranns@cisco.com>
