2019-05-16init / exit function orderingDave Barach1-6/+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 Ranns1-2/+15
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>
