2023-12-21fib: format deleted LBNathan Skrzypczak1-0/+8
This patch allows the formatting of deleted Load-balancer objects. This is needed in the case a trace references a DPO that went away in the interim. Type: improvement Change-Id: I6d67519b8d62f69aafde3c8fe3065bc85a7adbde Signed-off-by: Nathan Skrzypczak <nathan.skrzypczak@gmail.com>
2023-05-19fib: fix load-balance and replicate dpos buckets overflowBenoît Ganne1-0/+10
load-balance and replicate dpos both store their number of buckets as u16, which can overflow if too many paths are configured. For load-balance it can happens quite quickly because of weights normalization. Type: fix Change-Id: I0c78c39fc3d40626dfc58b49e7d99d71f9852b50 Signed-off-by: Benoît Ganne <bganne@cisco.com>

keep the number of buckets in the load-balanced fixed. If a path goes dwon fill its buckets with those from the next available up path. Change-Id: I15603ccb899fa9b77556b898c99136379cf32eae Signed-off-by: Neale Ranns <nranns@cisco.com>
2018-05-04Harmonize vec/pool_get_aligned object sizes and alignment requestsDave Barach1-0/+6
Object sizes must evenly divide alignment requests, or vice versa. Otherwise, only the first object will be aligned as requested. Three choices: add CLIB_CACHE_LINE_ALIGN_MARK(align_me) at the end of structures, manually pad to an even divisor or multiple of the alignment request, or use plain vectors/pools. static assert for enforcement.

2017-12-09BIER in non-MPLS netowrksNeale Ranns1-0/+1
as decsribed in section 2.2 ihttps://tools.ietf.org/html/draft-ietf-bier-mpls-encapsulation-10 with BIFT encoding from: https://tools.ietf.org/html/draft-wijnandsxu-bier-non-mpls-bift-encoding-00 changes: 1 - introduce the new BIFT lookup table. BIER tables that have an associated MPLS label are added to the MPLS-FIB. Those that don't are added to the BIER table 2 - BIER routes that have no associated output MPLS label will add a BIFT label. 3 - The BIER FMask has a path-list as a member to resolve via any possible path.

2017-01-27IP Multicast FIB (mfib)Neale Ranns1-0/+8
- IPv[46] mfib tables with support for (*,G/m), (*,G) and (S,G) exact and longest prefix match - Replication represented via a new replicate DPO. - RPF configuration and data-plane checking - data-plane signals sent to listening control planes. The functions of multicast forwarding entries differ from their unicast conterparts, so we introduce a new mfib_table_t and mfib_entry_t objects. However, we re-use the fib_path_list to resolve and build the entry's output list. the fib_path_list provides the service to construct a replicate DPO for multicast. 'make tests' is added to with two new suites; TEST=mfib, this is invocation of the CLI command 'test mfib' which deals with many path add/remove, flag set/unset scenarios, TEST=ip-mcast, data-plane forwarding tests. Updated applications to use the new MIFB functions; - IPv6 NS/RA. - DHCPv6 unit tests for these are undated accordingly.

2017-01-05FIB memory leaks (VPP-578)Neale Ranns1-1/+1
1) vec_free the fe_srcs of a fib_entry_t when the fib_entry_t is itself reed 2) in the load-balance fixup if a drop path is required add this to a new vector of next-hops 'fixed_nhs'. This vector is managed by the load-balance function. The caller continues to manage its own set. The function is now const implying that the caller is safe to assume the next-hops do not change.
