2023-05-21mpls: implement state change callbacksAdrian Pistol1-5/+12
There was already a basic type defined, but nothing more. This implements callbacks similar to ip4_enable_disable_interface_callback_t. Type: feature Change-Id: I34fcb146ca68af4eb8cdd244529eb149f884284d Signed-off-by: Adrian Pistol <vifino@posteo.net>

2021-10-11ip: fix fib and mfib locksNathan Skrzypczak1-3/+2
This patches fixes an issue that could cause fib locks to underflow: if an API user deletes a fib and quickly recreates it, the fib may not have been actually deleted. As a result, the lock would not be incremented on the create call leading to the fib potentially disappearing afterwards - or to the lock to underflow when the fib is deleted again. In order to keep the existing API semantics, we use the locks with API and CLI source as flags. This means we need to use a different counter for the interface-related locks. This also prevents an issue where an interface being bound to a vrf via API and released via CLI could mess up the lock counter. Finally, this will help with cleaning up the interface-related locks on interface deletion in a later patch.

2019-11-26fib: Table ReplaceNeale Ranns1-2/+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.

2017-09-11FIB table add/delete APINeale Ranns1-9/+7
part 2; - this adds the code to create an IP and MPLS table via the API. - but the enforcement that the table must be created before it is used is still missing, this is so that CSIT can pass. Change-Id: Id124d884ade6cb7da947225200e3bb193454c555 Signed-off-by: Neale Ranns <nranns@cisco.com>
2017-04-01MTRIE Optimisations 2Neale Ranns1-23/+3
1) 16-8-8 stride. Reduce trie depth walk traded with increased memory in the top PLY. 2) separate the vector of protocol-independent (PI) fib_table_t with the vector of protocol dependent (PD) FIBs. PD FIBs are large structures, we don't want to burn the memory for ech PD type 3) Go straight to the PD FIB in the data-path thus avoiding an indirection through, e.g., a PLY pool.
