[PATCH 0/1] MR4530: d3drm: Set image->palette only once in d3drm_image_palettise (GCC).
by Alex Henrie (＠alexhenrie) 28 Nov '23

GCC 13 thinks that there is a use-after-free here and warns about it. We actually don't need to check the return value of realloc here at all because shrinking an allocation is guaranteed to succeed. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/4530

[PATCH 0/1] MR4414: server: Fully initialize pe mapping struct to avoid uninitialized memory when...
by Fabian Maurer (＠DarkShadow44) 28 Nov '23

28 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) ``` -- https://gitlab.winehq.org/wine/wine/-/merge_requests/4414
