2024-02-16udp: unregister ports on all cleanupsFlorin Coras1-4/+3
UDP transport port refcount is incremented even if port is shared. So decrement it, by unregistering, whener udp connections are cleaned up. Type: fix Signed-off-by: Florin Coras <fcoras@cisco.com> Change-Id: Id0a2c60c5faf4dea8b2cd9ded0334934ad9e918c

2024-01-09session: support for cl port reuseFlorin Coras1-12/+19
Adds support for connectionless listener port reuse. Until now, cl listeners had fifos allocated to them and therefore only one app worker could ever listen, i.e., a session cannot have multiple fifos. To circumvent the limitation, this separates the fifos from the listener by allocating new cl sessions for each app worker that reuses the app listener. Flows are hashed to app worker cl sessions but, for now, this is not a consistent/fixed hash.

2023-08-09session: async rx event notificationsFlorin Coras1-10/+5
Move from synchronous flushing of io and ctrl events from transports to applications to an async model via a new session_input input node that runs in interrupt mode. Events are coalesced per application worker. On the one hand, this helps by minimizing message queue locking churn. And on the other, it opens the possibility for further optimizations of event message generation, obviates need for rx rescheduling rpcs and is a first step towards a fully async data/io rx path.

2022-11-28udp: preallocate ports sparse vec mapFlorin Coras1-2/+80
Not ideal. The sparse vector used to map ports to next nodes assumes only a few ports are ever used. When udp transport is enabled this does not hold and, to make matters worse, ports are consumed in a random order. This can lead to a lot of slow updates to internal data structures which in turn can slow udp connection allocations until all ports are eventually consumed. Consequently, reallocate sparse vector, preallocate all ports and have them point to UDP_NO_NODE_SET. We could consider switching the sparse vector to a preallocated vector but that would increase memory consumption for vpp deployments that do not rely on host stack. For reference, populating one of the v4 or v6 sparse vectors in reverse order takes about 9.8s on a skylake cpu.

When computing the inner packet checksum, the code wrongly assumes that the IP version of the inner packet is the same of the outer one. On the contrary, it is perfectly possible to encapsulate v6 packets into v4 and viceversa, so we need to check the IP format of the inner header before calling vnet_calc_checksums_inline.

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.
