[PATCH v2 1/4] ws2_32: Use getifaddrs() and if_nametoindex() directly in interface_bind().
In order to avoid accessing iphlpapi. We will need to move this code to ntdll or the server, but we can't access iphlpapi from either. Even accessing a lower-level interface (i.e. ndis) is hard—we have no good way to enumerate ndis devices from either (without duplicating large parts of setupapi). Signed-off-by: Zebediah Figura <z.figura12(a)gmail.com> --- In terms of ws2_32 complexity, this code paths seems no more complex, or even simpler. However, it omits the fallback path using SIOCGIFCON, making getifaddrs() a hard requirement for UDP binding. I don't know what if anything this risks losing support for, but current versions of all major operating systems seem to support it (BSD, Linux, Mac, Android), and we're gated on IP_BOUND_IF or IP_UNICAST_IF anyway. v2: Intentionally link to and call the iphlpapi if_nametoindex(), which is a simple wrapper around libc anyway, by redefining the unix version. Eventually this code will be moved out of ws2_32 and this step will be unnecessary. dlls/ws2_32/socket.c | 79 ++++++++++++++++++++---------------- dlls/ws2_32/ws2_32_private.h | 8 ++++ 2 files changed, 51 insertions(+), 36 deletions(-) diff --git a/dlls/ws2_32/socket.c b/dlls/ws2_32/socket.c index bfe5ab186ee..ad2e3a1d683 100644 --- a/dlls/ws2_32/socket.c +++ b/dlls/ws2_32/socket.c @@ -1975,62 +1975,65 @@ static int WINAPI WS2_WSARecvMsg( SOCKET s, LPWSAMSG msg, LPDWORD lpNumberOfByte */ static BOOL interface_bind( SOCKET s, int fd, struct sockaddr *addr ) { +#if defined(HAVE_GETIFADDRS) && (defined(IP_BOUND_IF) || defined(LINUX_BOUND_IF)) struct sockaddr_in *in_sock = (struct sockaddr_in *) addr;
