[PATCH v2 0/1] MR4414: server: Fully initialize pe mapping struct to avoid uninitialized memory when...
by Fabian Maurer (＠DarkShadow44) 30 Nov '23

30 Nov '23

When running wineserver under valgrind there is a bunch of uninitialised bytes warnings when sending the req_get_mapping_info reply. This warning can easily be reproduced by running `valgrind wineserver -f` and then `winecfg`. Tested using self compiled wine. Reason is the `pe_image_info_t` struct having bitfields: ``` unsigned char contains_code : 1; unsigned char wine_builtin : 1; unsigned char wine_fakedll : 1; ``` The last 5 bits are never initialized. This MR fixes this by zeroing the entire struct before it is filled. I hope "issues" like this are allowed to be fixed so valgrind has less false positives. Valgrind message for reference: ``` ==628662== 716 errors in context 3 of 3: ==628662== Syscall param writev(vector[1]) points to uninitialised byte(s) ==628662== at 0x49C3A87: writev (writev.c:26) ==628662== by 0x14C2F3: send_reply (request.c:268) ==628662== by 0x14C50F: call_req_handler (request.c:316) ==628662== by 0x14C5D2: read_request (request.c:339) ==628662== by 0x158F52: thread_poll_event (thread.c:388) ==628662== by 0x120FC9: fd_poll_event (fd.c:505) ==628662== by 0x1212A6: main_loop_epoll (fd.c:599) ==628662== by 0x121882: main_loop (fd.c:955) ==628662== by 0x12CBE0: main (main.c:238) ==628662== Address 0x53ec56e is 62 bytes inside a block of size 88 alloc'd ==628662== at 0x48416D4: malloc (vg_replace_malloc.c:431) ==628662== by 0x1348D0: mem_alloc (object.c:119) ==628662== by 0x14BEB9: set_reply_data_size (request.c:160) ==628662== by 0x1301C1: req_get_mapping_info (mapping.c:1291) ==628662== by 0x14C494: call_req_handler (request.c:305) ==628662== by 0x14C5D2: read_request (request.c:339) ==628662== by 0x158F52: thread_poll_event (thread.c:388) ==628662== by 0x120FC9: fd_poll_event (fd.c:505) ==628662== by 0x1212A6: main_loop_epoll (fd.c:599) ==628662== by 0x121882: main_loop (fd.c:955) ==628662== by 0x12CBE0: main (main.c:238) ==628662== Uninitialised value was created by a client request ==628662== at 0x134873: mark_block_uninitialized (object.c:110) ==628662== by 0x1348EA: mem_alloc (object.c:120) ==628662== by 0x134B87: alloc_object (object.c:199) ==628662== by 0x134F92: create_named_object (object.c:337) ==628662== by 0x12F12B: create_mapping (mapping.c:939) ==628662== by 0x12FFE9: req_create_mapping (mapping.c:1250) ==628662== by 0x14C494: call_req_handler (request.c:305) ==628662== by 0x14C5D2: read_request (request.c:339) ==628662== by 0x158F52: thread_poll_event (thread.c:388) ==628662== by 0x120FC9: fd_poll_event (fd.c:505) ==628662== by 0x1212A6: main_loop_epoll (fd.c:599) ==628662== by 0x121882: main_loop (fd.c:955) ``` -- v2: server: Fully initialize pe mapping struct to avoid uninitialized memory when sending req_get_mapping_info reply (valgrind) https://gitlab.winehq.org/wine/wine/-/merge_requests/4414

[PATCH 0/1] MR4566: ntdll/unix: Add an option to inherit the Unix console handle.
by Aida Jonikienė (＠DodoGTA) 30 Nov '23

I know this breaks Windows behavior but having apps print out special debug messages to the terminal provides a good look into the applications' development (for example I know that NFS Underground has some "done" messages likely used for debugging). I also don't want to keep another revert in my Wine tree just for this one feature either so that's why I'm MR'ing this. I considered adding a registry/winecfg entry for this behavior but it would make this change much larger (and there's no good place in winecfg to put this behavior in). To enable this behavior, you can set WINEDEBUG=+unixcon variable before launching an application.
