[PATCH 0/1] MR8073: ntdll: Unbreak new wow64 mode on FreeBSD.
by Alexander Shaikhulin (＠shkhln) 19 May '25

1. For %fs/fsbase the patch follows the macOS logic with LDT descriptor registration and Linux with switching. One notable difference is that on 32->64 transition we set %fs to GSEL(GUFS32_SEL, SEL_UPL) before restoring fsbase, otherwise FreeBSD will just revert it by reloading the selector [at the first opportunity](https://github.com/freebsd/freebsd-src/blob/5673462af5330df207…. GSEL(GUFS32_SEL, SEL_UPL) is the default %fs value on FreeBSD and is special-cased to save/restore actual fsbase value to/from PCB. 2. I was told we could get rid of fsbase glitches in signal handlers by blocking signals with [sigfastblock(2)](https://man.freebsd.org/cgi/man.cgi?query=sigfastblock) between %fs reset to the default value and fsbase reset to pthread_teb. This is currently a part of internal API for libthr, which could be exposed as pthread_signal_block_np for Wine. I'm on the fence whether it's worth it. 3. I fully admit I have no idea what registers are worth preserving around fallback syscalls to sysarch(AMD64_SET_FSBASE) and whether it's appropriate to push those to stack. ("Kernel" stack should be fine, I assume?) They definitely clobber r8-r11. 4. For %ss see https://lkml.org/lkml/2015/4/24/216. We don't have a similar workaround in the kernel, so it goes into Wine. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/8073

[PATCH 0/1] MR8071: ucrtbase/tests: Avoid reading behind buffer in test_swprintf (ASan).
by Bernhard Übelacker (＠bernhardu) 18 May '25

18 May '25

The test `test_swprintf` creates an un-terminated buffer and calls `WideCharToMultiByte` without explicit srclen on it. This patch wraps the buffer into a struct providing a termination without modifying the test itself. <details> <summary>ASan output:</summary> ``` ================================================================= ==ucrtbase_test.exe==532==ERROR: AddressSanitizer: stack-buffer-overflow on address 0x7ffffe1ffac0 at pc 0x6ffffe845638 bp 0x7ffffe1ff030 sp 0x7ffffe1ff078 READ of size 24 at 0x7ffffe1ffac0 thread T0 #0 0x6ffffe845637 in wcslen C:/llvm-mingw/llvm-mingw/llvm-project/compiler-rt/lib/asan/../sanitizer_common\sanitizer_common_interceptors.inc:7215:3 #1 0x6fffff7d1eff in lstrlenW .../wine/include/winbase.h:2574:5 #2 0x6fffff7d2a33 in WideCharToMultiByte .../wine/dlls/kernelbase/locale.c:7382:30 #3 0x000140016e6c in test_swprintf .../wine/dlls/ucrtbase/tests/printf.c:196:9 #4 0x000140015f3e in func_printf .../wine/dlls/ucrtbase/tests/printf.c:891:5 #5 0x00014002da0e in run_test .../wine/include/wine/test.h:765:5 #6 0x00014002d53a in main .../wine/include/wine/test.h:884:12 #7 0x00014002f005 in mainCRTStartup .../wine/dlls/msvcrt/crt_main.c:58:11 #8 0x6fffffc355be in BaseThreadInitThunk .../wine/dlls/kernel32/thread.c:61:24 #9 0x6fffffdbbcc2 in RtlUserThreadStart (C:\windows\system32\ntdll.dll+0x17004bcc2) Address 0x7ffffe1ffac0 is located in stack of thread T0 at offset 256 in frame #0 0x000140016b6f in test_swprintf .../wine/dlls/ucrtbase/tests/printf.c:176 This frame has 8 object(s): [32, 44) 'str_short' (line 177) [64, 80) 'str_justfit' (line 178) [96, 114) 'str_justfits' (line 179) [160, 182) 'str_muchlonger' (line 180) [224, 226) 'str_empty' (line 181) [240, 256) 'buffer' (line 184) [272, 280) 'narrow' (line 185) <== Memory access at offset 256 partially underflows this variable [304, 320) 'narrow_fmt' (line 185) HINT: this may be a false positive if your program uses some custom stack unwind mechanism, swapcontext or vfork (longjmp, SEH and C++ exceptions *are* supported) SUMMARY: AddressSanitizer: stack-buffer-overflow .../wine/include/winbase.h:2574:5 in lstrlenW Shadow bytes around the buggy address: 0x7ffffe1ff800: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 0x7ffffe1ff880: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 0x7ffffe1ff900: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 0x7ffffe1ff980: 00 00 00 00 00 00 00 00 f1 f1 f1 f1 00 04 f2 f2 0x7ffffe1ffa00: 00 00 f2 f2 00 00 02 f2 f2 f2 f2 f2 00 00 06 f2 =>0x7ffffe1ffa80: f2 f2 f2 f2 02 f2 00 00[f2]f2 00 f2 f2 f2 00 00 0x7ffffe1ffb00: f3 f3 f3 f3 00 00 00 00 00 00 00 00 00 00 00 00 0x7ffffe1ffb80: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 0x7ffffe1ffc00: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 0x7ffffe1ffc80: 00 00 00 00 00 00 00 00 f1 f1 f1 f1 f8 f8 f8 f8 0x7ffffe1ffd00: f8 f8 f8 f8 f3 f3 f3 f3 00 00 00 00 00 00 00 00 Shadow byte legend (one shadow byte represents 8 application bytes): Addressable: 00 Partially addressable: 01 02 03 04 05 06 07 Heap left redzone: fa Freed heap region: fd Stack left redzone: f1 Stack mid redzone: f2 Stack right redzone: f3 Stack after return: f5 Stack use after scope: f8 Global redzone: f9 Global init order: f6 Poisoned by user: f7 Container overflow: fc Array cookie: ac Intra object redzone: bb ASan internal: fe Left alloca redzone: ca Right alloca redzone: cb ``` </details> -- https://gitlab.winehq.org/wine/wine/-/merge_requests/8071
