2020-08-18fib: Fix interpose source reactivateNeale Ranns1-0/+14
Type: fix when the interpose is on an adj-fib and the cover is removed the adj source will not install. this lead to no path list being found for the interpose source and a crash. pick a drop path list in this case.

Add an ALWAYS_ASSERT (...) macro, to (a) shut up coverity, and (b) check the indicated condition in production images. As in: p = hash_get(...); ALWAYS_ASSERT(p) /* was ASSERT(p) */ elt = pool_elt_at_index(pool, p[0]); This may not be the best way to handle a specific case, but failure to check return values at all followed by e.g. a pointer dereference isn't ok.

2020-01-20fib: FIB crash removing labelled route (VPP-1818)Neale Ranns1-7/+12
Type: fix The crash occured trying to retreive a NULL path list to walk the path extensions. A walk shoul not be required, because there should be no extensins, since all paths are removed. The problem is that when the paths were added, they were not sorted, hence neither were the extensions and when they were updated, duplicate extensions were added, and hence a path removal did not remove them all. Fix is to make sure paths are sorted. Change-Id: I069d937de8e7bc8aae3d92f588db4daff727d863 Signed-off-by: Neale Ranns <nranns@cisco.com>

2019-07-19fib: FIB Entry trackingNeale Ranns11-64/+409
Instead of all clients directly RR sourcing the entry they are tracking, use a deidcated 'tracker' object. This tracker object is a entry delegate and a child of the entry. The clients are then children of the tracker. The benefit of this aproach is that each time a new client tracks the entry it doesn't RR source it. When an entry is sourced all its children are updated. Thus, new clients tracking an entry is O(n^2). With the tracker as indirection, the entry is sourced only once.

2019-06-26fib: adj cover refinement check changeNeale Ranns1-1/+3
Usually the adj cover refinement check which ensures that for any adj sourced prefix its cover is connected, is satified by the presence of the interface source. The interface source has a high priority hence during the adj refinement check get_flags() which uses the best source, usually returns the flags for the interface source. However, in the presence of higher priority sources that interpose get_flags does not return connected and the check fails. With this change add a specific check for the interface source if the best is not connected.

2019-06-18fib: fib api updatesNeale Ranns14-515/+937
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 Barach2-15/+13
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.
