J. Nick Koston	e7c126d3dc	[socket] Rename UDP socket types so UDPSocket is the full send+recv type Swap the UDP type naming so the unsuffixed UDPSocket is the full send+recv socket and the send-only variant becomes UDPSendSocket. The previous naming inverted reader expectations (UDPSocket sounded complete but was send-only, UDPRecvSocket sounded limited but was the full one). Public: UDPSocket (was UDPRecvSocket) UDPSendSocket (was UDPSocket) socket_udp (was socket_udp_recv) socket_ip_udp (was socket_ip_udp_recv) socket_udp_loop_monitored (was socket_udp_recv_loop_monitored) socket_ip_udp_loop_monitored (was socket_ip_udp_recv_loop_monitored) socket_udp_send (was socket_udp) socket_ip_udp_send (was socket_ip_udp) Internal: LWIPRawUDPImpl (was LWIPRawUDPRecvImpl) LWIPRawUDPSendImpl (was LWIPRawUDPImpl) No consumers exist yet, so this is a clean rename with no migration.	2026-04-10 18:40:14 -10:00

J. Nick KostonandClaude Opus 4.6	519be06e73	[socket] Add LWIP_LOCK to UDP socket methods for RP2040 safety On RP2040, lwip callbacks run from a low-priority IRQ context and can preempt main-loop code. All lwip API calls from the main loop must hold the async_context lock (LWIP_LOCK) to prevent races on shared lwip state (PCB lists, pbuf pools, IGMP groups). The TCP implementation was already correct; the UDP methods were missing the lock. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>	2026-03-14 15:57:57 -10:00

Nick Koston	fccfab8083	[socket] Switch UDP rx queue from lock-free SPSC to count-based with LWIP_LOCK With the lwip lock infrastructure in place from the TCP race fix, the lock-free SPSC ring buffer's wasted slot is no longer needed. Switch to a simple rx_count_ approach that uses all 4 queue slots. Also add LWIP_LOCK() to all UDP methods that call lwip APIs (bind, close, sendto, setsockopt, getsockopt, recvfrom, factories).	2026-03-10 01:15:57 -10:00

J. Nick Koston	49ba08cec9	[socket] Add lwip raw UDP socket implementation Add native UDP support to the lwip raw TCP socket layer used by ESP8266 and RP2040, eliminating the need for Arduino WiFiUDP fallback.

J. Nick Koston	81d12fd14a	[socket] Hold lwip lock for entire write() operation Same pattern as writev — write() calls internal_write_() then internal_output_(), each acquiring the lock separately.

J. Nick Koston	cc05bf3ed2	[socket] Add LWIP_LOCK to socket factory functions tcp_new() is an lwip core API call that must be bracketed with the lwip lock on RP2040 per pico-sdk docs. Add LWIP_LOCK() to socket() and socket_listen() factory functions.	2026-03-10 00:55:34 -10:00
J. Nick Koston	c182c0c74f	[socket] Hold lwip lock for entire readv/writev scatter-gather operation Avoid repeated lock acquire/release cycles per iovec element. The recursive mutex re-entry in inner calls is nearly free (counter bump), while the outer lock prevents the expensive IRQ disable/enable on each iteration.	2026-03-10 00:53:01 -10:00
J. Nick Koston	a88e9b8146	[socket] Fix RP2040 TCP race condition between lwip callbacks and main loop On RP2040 (Pico W), arduino-pico sets PICO_CYW43_ARCH_THREADSAFE_BACKGROUND=1, which means lwip callbacks (recv_fn, accept_fn, err_fn) run from a PendSV interrupt — not the main loop. This allows them to preempt read(), write(), close(), and accept() at any point, causing race conditions on shared state like the rx_buf_ pbuf chain. The most critical race: recv_fn calls pbuf_cat(rx_buf_, pb) while read() is freeing nodes in the same chain, leading to use-after-free and lwip's "Creating an infinite loop" assertion panic. This is the root cause of #10681. Fix: implement RP2040's LwIPLock (previously a no-op) to call cyw43_arch_lwip_begin/end, which acquires the pico-sdk async_context recursive mutex. Add LWIP_LOCK() guards to all main-loop lwip API call sites in the socket layer. On ESP8266, lwip callbacks run cooperatively from the main loop, so LwIPLock remains a no-op.
