2022-03-24mpls: Set the MTU field in the frag-needed ICMP when doing MPLS fragmentationNeale Ranns1-4/+3
Type: fix The reported MTU should include the MPLS label overhead Signed-off-by: Neale Ranns <neale@graphiant.com> Change-Id: I3df6d2e0b13f49701e187a766a157498dcaafbc0
2022-03-07ip: Fixes for IPv6 and MPLS fragmentationNeale Ranns1-41/+64
Type: fix - IPv6 fragmentation did not work if the packet spaneed multiple buffers, because the 'len' calculation to did max out at the size of a buffer - IPv6 fragmentation did not work when the l2unfragmentable size was non-zero, it was not used in the correct places - IPv6oMPLS fragmentation would fragment all IPv6, it should do so only for link local - IPv6oMPLS should send back TooBig ICMP6 for non locally generated Signed-off-by: Neale Ranns <neale@graphiant.com> Change-Id: Ie8f02cdfdd7b7e8474e62b6d0acda8f20c371184
2022-03-04mpls: Fix the fragmentation in mpls-output.Neale Ranns1-84/+80
Type: fix the MTU needs to be adjusted to account for the label stack, since the size of fragments produced is stack+mtu. these changes are to the use of the stack variable 'mtu' most of the patch results from appeasing checkstyle.

2020-04-09mpls: fix typo in error pathDave Barach1-10/+9
if ip4_frag_do_fragment(...) returns an error due to buffer allocation failure, we end up trying to increment a nonexistent counter, which causes an ASSERT failure. The second argument to vlib_error_count is a node index, not a next index... Type: fix Signed-off-by: Dave Barach <dave@barachs.net> Change-Id: Ib0733b0d35bcb9d3ca6bd789e0c5ddc1561ce724
2019-11-11ip: functional interface to ip fragmentationOle Troan1-37/+181
This provides a functional interface to IP fragmentation. Allowing external features to fragment. Supports arbitrary encap size, for e.g. MPLS or inner fragmentation of tunnels. This also removed dual loop in MAP that was fundamentally broken.

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>
