Detailed Description

Kernel socket state.

One net_sock_t per open socket fd. Owns the lwIP PCB pointer and a 2-slot receive ring for RAW sockets (UDP/TCP use slot 0 only). No dynamic allocation beyond the static pool.

Member Data Documentation

_pad2

uint8_t net_sock::_pad2[2]

connected

int net_sock::connected

Non-zero after connect/accept

in_use

int net_sock::in_use

Pool slot occupied flag

pcb

void* net_sock::pcb

lwIP PCB: udp_pcb* or tcp_pcb*

poll_waiter_tid

uint32_t net_sock::poll_waiter_tid

tid of thread sleeping in poll/select for this socket; 0 = none

proto

SOCK_PROTO_UDP, SOCK_PROTO_TCP, or SOCK_PROTO_RAW

rcvtimeo_ticks

uint32_t net_sock::rcvtimeo_ticks

SO_RCVTIMEO as LAPIC ticks (10ms each); 0 = use 10s default

rx_head

uint8_t net_sock::rx_head

Consumer index (monotonic uint8 wrap; mask with (NET_SOCK_RX_RING_SLOTS-1))

rx_ring

net_sock_rx_entry_t net_sock::rx_ring[NET_SOCK_RX_RING_SLOTS]

2-slot RAW burst buffer; UDP/TCP use slot 0 only

rx_tail

uint8_t net_sock::rx_tail

Producer index (monotonic uint8 wrap)
