[PATCH v4 0/1] MR6191: ws2_32: Fully implement socket options IPX_ADDRESS and IPX_MAX_ADAPTER_NUM on Linux
Tested using C&C Red Alert 2; selection of interface and network communication worked as expected. IPX traffic correctly sent to the selected interface only, as confirmed by **tcpdump(8)**.  -- v4: ws2_32: Fully implement socket options IPX_ADDRESS and IPX_MAX_ADAPTER_NUM on Linux https://gitlab.winehq.org/wine/wine/-/merge_requests/6191
From: 王昊然 <whr(a)rivoreo.one> Move implementation of these 2 options into ntdll, and add 2 ioctl codes for calling from ws2_32. Query configured IPX interfaces by reading /proc/net/ipx/interface of Linux procfs, enabling applications to iterate multiple IPX interfaces. This can be useful when a node have multiple IPX interfaces, and application need to receive/send packets from/to a non-primary IPX interface. --- dlls/ntdll/unix/socket.c | 141 +++++++++++++++++++++++++++++++++++++++ dlls/ws2_32/socket.c | 37 +++------- include/wine/afd.h | 2 + 3 files changed, 151 insertions(+), 29 deletions(-) diff --git a/dlls/ntdll/unix/socket.c b/dlls/ntdll/unix/socket.c index 53292246648..8adc4be59de 100644 --- a/dlls/ntdll/unix/socket.c +++ b/dlls/ntdll/unix/socket.c @@ -78,6 +78,7 @@ #include "ws2tcpip.h" #include "wsipx.h" #include "af_irda.h" +#include "wsnwlink.h" #include "wine/afd.h" #include "unix_private.h" @@ -2426,6 +2427,146 @@ NTSTATUS sock_ioctl( HANDLE handle, HANDLE event, PIO_APC_ROUTINE apc, void *apc return do_setsockopt( handle, io, 0, SO_DEFAULT_HEADERS, &value, sizeof(value) ); } #endif + case IOCTL_AFD_WINE_GET_IPX_ADDRESS: + { + const IPX_ADDRESS_DATA *in_data; + IPX_ADDRESS_DATA *out_data; +#ifdef __linux__ + FILE *f; + int c; + int nlines; +#else + union unix_sockaddr addr; + struct WS_sockaddr_ipx ws_addr; + socklen_t namelen; +#endif + + /* + * On a Win2000 system with one network card there are usually + * three ipx devices one with a speed of 28.8kbps, 10Mbps and 100Mbps. + * Using this call you can then retrieve info about this all. + * In case of Linux it is a bit different.
