This shamelessly steals the model established in the UDP workers, i.e.
if the kernel is able to bind multiple listening sockets to the same
endpoint, we will share them across threads. If it can't, all threads
will accept on the same socket.
The fast path handles most of the connections, only the rare case of
no data yet on the socket is offloaded to the slow path (which used to
be the mainloop) for completion. This scales nicely, as the higher the
load is, the higher chances are that an accept happens only after the
network roundtrip to the peer completes, leading to more connections
that already have data waiting for us.
We also consolidate the workstruct init and deinit code, preparation
for later unifying all thread state structs for all protocols (mca,
udc and tcp).
The config file gains a per tcp connection worker count and some docs
explaining what this knob buys and costs, nudging the user to either
keep it 0 or dial it up to at least 2.
Introduce a fast path assuming that a tcp connection's payload already has arrived at accept time2026-10-30T22:11:41ZDirk Englingerdgeist@erdgeist.org2026-10-30T22:11:41Zurn:sha1:15f9f81b5a8398fefca023e90d8d1c168ecef620Enforce the invariant that each socket is only ever expected to be read from or written to, never both2026-10-30T12:17:39ZDirk Englingerdgeist@erdgeist.org2026-10-30T12:17:39Zurn:sha1:cbf4b60df6c6c8c7208dc29708677d24b2724debDon't treat a full send buffer as an error when sending http.
