[PATCH v34 0/8] MR7650: Add support for AF_UNIX sockets (followup)
Follow-up of !2786, which appears to have been abandoned. Depends on !8182, !8575 # Execute minimal test case 1. checkout wine into ~/src/wine 2. in dlls/ws2_32/tests/sock.c wrap all calls to test functions after `Init()` until `test_afunix()` with #if 0 ... #endif 3. build into ~/src/wine-build 4. run `(cd ~/src/wine-build; WINEPREFIX=~/src/wine/.wine ../wine/tools/runtest -q -P wine -T . -M ws2_32.dll -p dlls/ws2_32/tests/i386-windows/ws2_32_test.exe sock)` # How to debug wineserver Since `wineserver` runs in the background, simple calls to printf() will show nothing when the test case is executed. A workaround is to open a file and call fprintf() to write debug messages to this file, which can then be inspected. -- v34: ws2_32: Add note in bind() for AF_UNIX sockets ws2_32/tests: In tests for AF_UNIX sockets print actual directory used ws2_32/tests: In AF_UNIX socket tests always print used path in case of errors ws2_32/tests: Add test for AF_UNIX sockets server: Fix getsockname() and accept() on AF_UNIX sockets. server: Introduce error when attempting to create a SOCK_DGRAM AF_UNIX socket. server: Allow for deletion of socket files. ws2_32: Add support for AF_UNIX sockets. https://gitlab.winehq.org/wine/wine/-/merge_requests/7650
From: Ralf Habacker <ralf.habacker(a)freenet.de> This commit additionally modifies wineserver's sock_ioctl to handle the provided pathname by changing directories and then returning after the native call. This is NOT threadsafe, but wineserver is not multithreaded. --- dlls/ntdll/unix/socket.c | 4 + dlls/ws2_32/socket.c | 83 +++++++++++++++++-- dlls/ws2_32/ws2_32_private.h | 13 +++ server/sock.c | 152 ++++++++++++++++++++++++++++++++--- 4 files changed, 238 insertions(+), 14 deletions(-) diff --git a/dlls/ntdll/unix/socket.c b/dlls/ntdll/unix/socket.c index 5156bbfee10..1f484283757 100644 --- a/dlls/ntdll/unix/socket.c +++ b/dlls/ntdll/unix/socket.c @@ -67,6 +67,8 @@ # define HAS_IRDA #endif +#include <sys/un.h> + #include "ntstatus.h" #define WIN32_NO_STATUS #include "windef.h" @@ -78,6 +80,7 @@ #include "ws2tcpip.h" #include "wsipx.h" #include "af_irda.h" +#include "afunix.h" #include "wine/afd.h" #include "unix_private.h" @@ -106,6 +109,7 @@ union unix_sockaddr #ifdef HAS_IRDA struct sockaddr_irda irda;
