[PATCH v27 0/1] 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.* -- v27: server: Move getpeername() implementation from ntdll/unix. 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. This commit also removes todo_wine from multiple now-successful tests. --- dlls/ntdll/unix/socket.c | 24 ++--------------- dlls/ws2_32/tests/sock.c | 18 ++++++------- server/sock.c | 58 +++++++++++++++++++++++++++++++++++++++- 3 files changed, 68 insertions(+), 32 deletions(-) diff --git a/dlls/ntdll/unix/socket.c b/dlls/ntdll/unix/socket.c index e09bf34b07d..32eba1af088 100644 --- a/dlls/ntdll/unix/socket.c +++ b/dlls/ntdll/unix/socket.c @@ -1939,30 +1939,10 @@ NTSTATUS sock_ioctl( HANDLE handle, HANDLE event, PIO_APC_ROUTINE apc, void *apc } case IOCTL_AFD_WINE_GETPEERNAME: - { - union unix_sockaddr unix_addr;

Hi, It looks like your patch introduced the new failures shown below. Please investigate and fix them before resubmitting your patch. If they are not new, fixing them anyway would help a lot. Otherwise please ask for the known failures list to be updated. The tests also ran into some preexisting test failures. If you know how to fix them that would be helpful.

This being guarded out by getsockname() succeeding looks wrong. This is broadly true of the other calls to getpeername(), but this one especially looks wrong. It's a bit of a moot point since we don't expect getsockname() or getpeername() to fail, but it does look confusing. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/3074#note_45782
Sorry for the long delay. As I mentioned I was hoping to see the AF_UNIX stuff upstream first, but that's clearly stalled, so I've gone ahead and reviewed this. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/3074#note_45783
