2021-06-01udp: calculate inner checksums if needed before udp encapArthur de Kerhor2-1/+7
We do not want to encap headers containing wrong checksums. Additionnally, this clears the checksums offlads flags, which was something missing since the outer headers checksums were calculated during the encap. Hence, those should not be recalculated afterwards. Type: fix Change-Id: I7fd07987b4f13f76c6990a1c08dc2f960bdd8de1 Signed-off-by: Arthur de Kerhor <arthurdekerhor@gmail.com>

2021-02-15vlib: refactor checksum offload supportMohsin Kazmi1-1/+1
Type: refactor This patch refactors the offload flags in vlib_buffer_t. There are two main reasons behind this refactoring. First, offload flags are insufficient to represent outer and inner headers offloads. Second, room for these flags in first cacheline of vlib_buffer_t is also limited. This patch introduces a generic offload flag in first cacheline. And detailed offload flags in 2nd cacheline of the structure for performance optimization.

2020-06-27udp: align udp_encap_t_ to 2 cachelinesVadym Martsynovskyy1-4/+4
Based on the comments in the struct, udp_encap_t_ is meant to span 2 cachelines. Due to the 64 bit alignment of dpo_id_t, the struct spanned 3 cachelines. This caused fetching ue_ip_proto to trigger an additional cache miss. This patch rearranges the ordering of the struct fields so that udp_encap_t_ only spans 2 cachelines as intended. before: (gdb) print (int)&((struct udp_encap_t_*)0)->cacheline1 $8 = 128 after: (gdb) print (int)&((struct udp_encap_t_*)0)->cacheline1 $1 = 64 Type: fix Signed-off-by: Vadym Martsynovskyy <vmartsyn@fb.com> Change-Id: I066c08654d4a8ef3e2d3954e957d4c5d382b209f

2019-07-19fib: FIB Entry trackingNeale Ranns1-11/+6
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.
