2023-11-10gtpu: support non-G-PDU packets and PDU SessionRune E. Jensen8-527/+2551
Updated the gtpu plugin code to support the PDU Session user plane protocol, required for 5G, as specified in 3GPP TS 38.415 version 17.0.0. This enables some initial support of 5G gNodeB's with the gtpu plugin. New features: - Basic support for the GTP-U Extension Header Flag. Packets with one extension can now be decapsulated. This enables basic support of the PDU Session user plane protocol (3GPP TS 38.415 version 17.0.0). New tunnels can be created with a PDU enable flag and a 6-bit QoS Flow Identifier (QFI). With this, encapsulated packets will have the PDU Session extension header, and the QFI set. - Ability to forward GTP-U packets that are not handled by the plugin directly. Only GTP-U packets with a message type of 255 (G-PDU) are handled directly. However, 3GPP TS 29.281 defines several other message types like echo and error indication. A new feature is added to optionally forward unknown or unsupported packets to a new IP address. This works separately for unknown GTP-U message types, unknown TEIDs, and packets with an unknown GTP-U header. This allows both echo and error indications from a 5G gNodeB to be handled by a different system outside VPP. - Simple way to get metrics for active tunnels and on tunnel close. In 5G session/tunnel lifetime is often short and created frequently. The normal API becomes too slow and inaccurate when too many tunnels are created and deleted every second. Improvements: - A clean ground structure to handle multiple message type in the future. The code path for G-PDU packets is optimized for performance, representing the typical case. Unsupported GTP-U packets enter a slow path that decodes the nature of the error. This presents a easy hook to handle other message types in the future. - Improved error reporting When using traces there is more details in the tunnel descriptions. - Updated the API with several enums. Fixes: - gtpu0->length field in IPv6 was computed with IPv4 header lengths in the encapsulation code. - vec_set_len (t->rewrite, ...) size was computed with the IPv4 header size also for IPv6 tunnels. Issues: - This PR does not enable full support of the 3GPP specification. In particular it only supports a single QoS/QFI flow for each tunnel. It ignores all incoming extension header flags. - API functions might change again when/if more support of the 3GPP TS 38.415 spec is added. Note that I have bumped the API version to 2.1.0 as it seems to be the correct approach based on my API changes. Type: feature Signed-off-by: Rune E.

2021-10-21fib: respect mfib entry flags on create with pathsPaul Atkins1-5/+6
When an mfib entry was created with both paths and entry_flags then the entry flags were being ignored. If there are no paths then the flags were passed into mfib_table_entry_update, but in the case where the entry didn't exist and there were paths and flags, the entry was created within mfib_table_entry_paths_update() which used a default of MFIB_ENTRY_FLAG_NONE. Pass the flags through into the mfib_table_entry_paths_update fn. All existing callers other than the create case will now pass in MFIB_ENTRY_FLAG_NONE.

2021-02-15vlib: refactor checksum offload supportMohsin Kazmi1-7/+9
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.

2020-09-04ip: enhance vtep4_check of tunnel by vector wayZhiyong Yang1-12/+30
This patch aims to improve decap performance by reducing expensive hash_get callings as less as possible using AVX512 on XEON. e.g. vxlan, vxlan_gpe, geneve, gtpu. For the existing code, if vtep4 of the current packet match the last vtep4_key_t well, expensive hash computation can be avoided and the code returns directly. This patch improves tunnel decap multiple flows case greatly by leveraging 512bit vector register on XEON accommodating 8 vtep4_keys. It enhances the possiblity of avoiding unnecessary hash computing once hash key of the current packet hits any one of 8 in the 512bit cache. The oldest element in vtep4_cache_t is updated in round-robin order. vlib_get_buffers is also leveraged in the meanwhile.

2019-06-18fib: fib api updatesNeale Ranns1-7/+5
Enhance the route add/del APIs to take a set of paths rather than just one. Most unicast routing protocols calcualte all the available paths in one run of the algorithm so updating all the paths at once is beneficial for the client. two knobs control the behaviour: is_multipath - if set the the set of paths passed will be added to those that already exist, otherwise the set will replace them. is_add - add or remove the set is_add=0, is_multipath=1 and an empty set, results in deleting the route. It is also considerably faster to add multiple paths at once, than one at a time: vat# ip_add_del_route 1.1.1.1/32 count 100000 multipath via 10.10.10.11 100000 routes in .572240 secs, 174751.80 routes/sec vat# ip_add_del_route 1.1.1.1/32 count 100000 multipath via 10.10.10.12 100000 routes in .528383 secs, 189256.54 routes/sec vat# ip_add_del_route 1.1.1.1/32 count 100000 multipath via 10.10.10.13 100000 routes in .757131 secs, 132077.52 routes/sec vat# ip_add_del_route 1.1.1.1/32 count 100000 multipath via 10.10.10.14 100000 routes in .878317 secs, 113854.12 routes/sec vat# ip_route_add_del 1.1.1.1/32 count 100000 multipath via 10.10.10.11 via 10.10.10.12 via 10.10.10.13 via 10.10.10.14 100000 routes in .900212 secs, 111084.93 routes/sec Change-Id: I416b93f7684745099c1adb0b33edac58c9339c1a Signed-off-by: Neale Ranns <neale.ranns@cisco.com> Signed-off-by: Ole Troan <ot@cisco.com> Signed-off-by: Paul Vinciguerra <pvinci@vinciconsulting.com>
