Hello:

This patch series introduces bpf_ksock, a set of BPF kfuncs to allow BPF
programs to create UDP sockets and send data. This provides a mechanism
for BPF LSM progs to emit telemetry over UDP independently of userspace.

The main use case is to be able to completely dispense with
agents/daemons for BPF programs after startup. In the case of
Isovalent's Tetragon, the idea would be to be able to emit security
alerts or export data from BPF even when the agent is down. For meta,
according to Liam presentation[^2], this could replace logging via
ringbuffers which created cross-binary versioning issues.
