Added BSD recvfromto support (#376)

2026-05-29T14:34:38Z

* recvfromto support * nx_bsd_inet_aton, disabling other format than four numbers separated by dots. Otherwise used in nx_bsd_inet_pton It accepts unallowed format of IP address. * bsd: address PR review feedback - Fix build failure: add missing nx_bsd_recvfromto() prototype to nxd_bsd.h near the other receive prototypes. The nx_bsd_recvfromto macro maps to recvfromto, but without a prior declaration the compiler emits -Werror=missing-declarations. - Revert inet_aton() change: restore the 1-part, 2-part and 3-part abbreviated IPv4 address formats (a.b.c and a.b). The PR removed them, breaking existing tests that rely on these forms. - Add IPv6 destination address support in recvfromto(): when the receiving BSD socket is AF_INET6, extract the destination IPv6 address from the IPv6 packet header and populate a sockaddr_in6 in toAddr, mirroring the existing IPv4 path. - Add regression test netx_bsd_recvfromto_test covering: * recvfromto() populates fromAddr (sender) and toAddr (destination) with correct address/port values for IPv4 UDP * recvfromto() with NULL toAddr/toAddrLen works like recvfrom() * inet_aton() still accepts abbreviated a.b and a.b.c forms Register test in regression/CMakeLists.txt. --------- Co-authored-by: Frédéric Desbiens Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

Implemented BSD select improvements (#375)

2026-05-29T13:15:07Z

* initial support * bsd: address PR review feedback - Fix accept() regression: preserve accepted socket FD even when recreating the secondary listen socket fails due to slot exhaustion. Set secondary_socket_id = NX_BSD_MAX_SOCKETS to invalidate the slot for future accept() calls, but still return the already-accepted FD. - Restore select() writefds 'not in use' case: closed/unallocated descriptors must be reported immediately as writable per BSD semantics. Several tests (netx_bsd_tcp_basic_blocking_test, _rcvbuf_test, _getaddrinfo_test) depend on this behaviour. - Fix select() exceptfds race with readfds: the readfds scan calls nx_tcp_socket_receive() which dequeues the head packet; a subsequent peek at nx_tcp_socket_receive_queue_head in the exceptfds scan then finds NULL. Move the URG/push-flag check into the readfds scan immediately after the successful dequeue while the packet is still accessible. - Add regression test netx_bsd_select_improvements_test covering: * zero-timeout select clears all fdsets without blocking * normal TCP data sets readfds, not exceptfds * a not-in-use descriptor appears in writefds Register test in regression/CMakeLists.txt. --------- Co-authored-by: Frédéric Desbiens Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

Implemented BSD socket options improvements (#374)

2026-05-28T20:23:22Z

● - initial support - bsd: address PR review feedback - Fix build failure: so_linger was stored on NX_TCP_SOCKET which has no such field. Linger state is now kept in NX_BSD_SOCKET using the new nx_bsd_option_linger field and the existing NX_BSD_SOCKET_ENABLE_OPTION_LINGER flag. - Fix sign-conversion warning in setsockopt(IP_TOS): read the value as INT, validate range 0..0xFF, then cast to ULONG. - Reject out-of-range INT values (< 0 or > 255) in setsockopt(IP_TTL). - Add lower-bound check for IPPROTO_IP options in getsockopt and setsockopt so that SO_* option numbers are no longer silently accepted at the IPPROTO_IP level. - Add null check for raw sockets in IP_TOS and IP_TTL get/set paths; return ENOPROTOOPT instead of dereferencing a NULL pointer. - Validate *option_length before writing in SO_BROADCAST, TCP_NODELAY, SO_LINGER and IP_TOS getsockopt paths; set *option_length to the actual size returned on success. - Separate ENOPROTOOPT (wrong socket type) from EINVAL (wrong length) in SO_LINGER get/set error handling. - Remove unused so_linger local variable from getsockopt. - Replace C++-style // comments in the close/linger path with C99 /* */ comments. - Add regression test netx_bsd_socket_options_test covering SO_LINGER, IP_TOS, IP_TTL, SO_BROADCAST and TCP_NODELAY round-trips and error paths; register in bsd_test_cases in regression/CMakeLists.txt.

Updated copyright headers and version strings. Removed version history

Added regression test and enhanced select fix for Issue #366

2026-03-06T18:06:56Z

fix: #366 Refactor `select()` socket suspend structures

2026-02-20T17:42:59Z

Refactored `select()` and `nx_bsd_select_wakeup()` to differentiate between requested event filter `nx_bsd_fd_set` and resulting active sockets `nx_bsd_fd_set`. This prevents spurious events being raised for sockets that are not part of the wakeup triggers.
