2020-03-10mpls: add user defined name tag to mpls tunnelsIJsbrand Wijnands4-4/+19
This allows a user creating MPLS tunnel through the bin_api to add a name tag. This is useful to correlate the Tunnel with its use-case. Also useful if the user needs to recover the MPLS Tunnel after a restart (mark-sweep).

2019-11-26fib: Table ReplaceNeale Ranns2-9/+0
Type: feature from the API doc, a table replace is: " The use-case is that, for some unspecified reason, the control plane has a very different set of entries it wants in the table than VPP currently has. The CP would thus like to 'replace' VPP's current table only by specifying what the new set of entries shall be, i.e. it is not going to delete anything that already eixts. the CP delcartes the start of this procedure with this begin_replace API Call, and when it has populated all the entries it wants, it calls the below end_replace API. From this point on it is of coursce free to add and delete entries as usual. The underlying mechanism by which VPP implements this replace is purposefully left unspecified. " In the FIB, the algorithm is implemented using mark and sweep. Algorithm goes: 1) replace_begin: this marks all the entries in that table as 'stale' 2) download all the entries that should be in this table - this clears the stale flag on those entries 3) signal the table converged: ip_table_replace_end - this removes all entries that are still stale this procedure can be used when an agent first connects to VPP, as an alternative to dump and diff state reconciliation.

2019-06-18fib: fib api updatesNeale Ranns3-275/+220
Enhance the route add/del APIs to take a set of paths rather than just one. Most unicast routing protocols calcualte all the available paths in one run of the algorithm so updating all the paths at once is beneficial for the client. two knobs control the behaviour: is_multipath - if set the the set of paths passed will be added to those that already exist, otherwise the set will replace them. is_add - add or remove the set is_add=0, is_multipath=1 and an empty set, results in deleting the route. It is also considerably faster to add multiple paths at once, than one at a time: vat# ip_add_del_route 1.1.1.1/32 count 100000 multipath via 10.10.10.11 100000 routes in .572240 secs, 174751.80 routes/sec vat# ip_add_del_route 1.1.1.1/32 count 100000 multipath via 10.10.10.12 100000 routes in .528383 secs, 189256.54 routes/sec vat# ip_add_del_route 1.1.1.1/32 count 100000 multipath via 10.10.10.13 100000 routes in .757131 secs, 132077.52 routes/sec vat# ip_add_del_route 1.1.1.1/32 count 100000 multipath via 10.10.10.14 100000 routes in .878317 secs, 113854.12 routes/sec vat# ip_route_add_del 1.1.1.1/32 count 100000 multipath via 10.10.10.11 via 10.10.10.12 via 10.10.10.13 via 10.10.10.14 100000 routes in .900212 secs, 111084.93 routes/sec Change-Id: I416b93f7684745099c1adb0b33edac58c9339c1a Signed-off-by: Neale Ranns <neale.ranns@cisco.com> Signed-off-by: Ole Troan <ot@cisco.com> Signed-off-by: Paul Vinciguerra <pvinci@vinciconsulting.com>

2019-05-16init / exit function orderingDave Barach1-11/+10
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.

2019-02-14Add -fno-common compile optionBenoît Ganne1-1/+1
-fno-common makes sure we do not have multiple declarations of the same global symbol across compilation units. It helps debug nasty linkage bugs by guaranteeing that all reference to a global symbol use the same underlying object. It also helps avoiding benign mistakes such as declaring enum as global objects instead of types in headers (hence the minor fixes scattered across the source).
