[PATCH v3 0/2] MR3074: Move getpeername() implementation to wineserver
`getpeername()` is currently handled in ntdll. This merge request changes ntdll to forward `getpeername()` to wineserver. The implementation utilises new `peer_addr` and `peer_addr_len` fields in wineserver's `struct sock`. This fixes multiple `todo_wine`s in `ws2_32/tests` and allows for more accurate peer names to be provided in case the address the socket is bound to on the Unix side does not match what `bind()` was called with on the Windows side. *This merge request was originally intended to be included in !2786 (Add support for AF_UNIX sockets) but was split into its own merge request because this is not an insignificant change.* -- v3: ws2_32/tests: Remove todo_wine from now-successful tests. https://gitlab.winehq.org/wine/wine/-/merge_requests/3074
From: Ally Sommers <dropbear.sh(a)gmail.com> This brings getpeername() in line with getsockname(), which is also implemented in wineserver. It also allows getpeername() to return a possibly-more-accurate peer name, as in the case of AF_UNIX sockets. --- dlls/ntdll/unix/socket.c | 24 ++------------------- server/sock.c | 45 +++++++++++++++++++++++++++++++++++++++- 2 files changed, 46 insertions(+), 23 deletions(-) diff --git a/dlls/ntdll/unix/socket.c b/dlls/ntdll/unix/socket.c index 4e706323a0a..8fcd366879b 100644 --- a/dlls/ntdll/unix/socket.c +++ b/dlls/ntdll/unix/socket.c @@ -1912,30 +1912,10 @@ NTSTATUS sock_ioctl( HANDLE handle, HANDLE event, PIO_APC_ROUTINE apc, void *apc } case IOCTL_AFD_WINE_GETPEERNAME: - { - union unix_sockaddr unix_addr;
