2019-06-19mpls: fix header offset overflowBenoît Ganne1-3/+6
rw_len (MPLS rewrite string length) is declared as unsigned but is used as -rw_len with vlib_buffer_advance(), resulting in a wrong, huge offset. Type: fix Fixes: 734d430f37251bc7e71d507983ee640ae1625fbe Ticket: VPP-1705 Change-Id: I7357249f7e50b7d30fd61f5be4858a26e43df85d Signed-off-by: Benoît Ganne <bganne@cisco.com>

2017-12-09BIER in non-MPLS netowrksNeale Ranns1-14/+0
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.

2017-04-06Use thread local storage for thread indexDamjan Marion1-5/+5
This patch deprecates stack-based thread identification, Also removes requirement that thread stacks are adjacent. Finally, possibly annoying for some folks, it renames all occurences of cpu_index and cpu_number with thread index. Using word "cpu" is misleading here as thread can be migrated ti different CPU, and also it is not related to linux cpu index.

2017-03-29Mtrie optimisationsNeale Ranns1-8/+0
1 - make the default route non-special, i.e. like any other less specific route. Consequently, all buckets have a valid valid index of either a leaf or a ply. Checks for special indeices in the data-path can thus be removed. 2 - since all leaves are now 'real' i.e. they represent a real load-balance object, to tell if a ply slot is 'empty' requeirs chekcing that the prefix length of the leaf occupying the slot is slot than the minium value for that ply. 3 - when removing a leaf find the cover first, then recurse down the ply and replace the old leaf with the cover. This saves us a ply walk. Change-Id: Idd523019e8bb1b6ef527b1f5279a5e24bcf18332 Signed-off-by: Neale Ranns <nranns@cisco.com>
