[PATCH 0/2] MR1162: ntdll: Use local unwinding reimplementations for Unix libraries on ARM
by Martin Storsjö (＠mstorsjo) 04 Nov '22

04 Nov '22

Currently, unwinding the unix libraries (or full ELF builds) requires having libunwind available. When starting up a wine environment, an exception of type `RPC_S_SERVER_UNAVAILABLE` gets thrown - and if libunwind isn't available, this breaks the startup. Thus, currently on ARM/ARM64, libunwind is essentially mandatory. Additionally, at least on ARM, libunwind seems brittle (commits in latest git master breaks the unwinding use cases in Wine, see e.g. https://github.com/libunwind/libunwind/pull/203#issuecomment-984126066. For ARM, libunwind has currently relied on DWARF debug info in the `.debug_frame` section, since Linux on ARM doesn't use DWARF for runtime unwinding. This MR adds ARM EHABI unwind opcodes where necessary, and adds a local reimplementation of an ARM EHABI/EXIDX/EXTBL unwinder, similar to the DWARF one. With these changes, unwinding on ARM seems to work fine, even without libunwind. See the individual commit messages for more commentary on the decisions taken so far (I've tried to write up all relevant considerations there - it's a fair amount of commentery). A couple open questions: - I wrote the ARM EHABI unwind code mostly with `stdint.h` types like `uint32_t`(as it's in the ntdll/unix directory anyway), but I can rewrite it with `DWORD` or similar if that's preferred. - The ARM EHABI opcodes are enabled for `defined(__arm__) && defined(__ELF__) && defined(__GNUC__) && !defined(__SEH__) && !defined(__ARM_DWARF_EH__)` - there's no define to check for for knowing it's used and enabled, but it has to be implicitly assumed if no other other unwind mechanism is signaled. - The `dl_iterate_phdr` function, used for finding the EXIDX section for locating ARM EHABI unwind info, is used within `#ifdef linux`. It might be available on other OSes too (like FreeBSD etc). Or should I go ahead and add a configure check for it? -- https://gitlab.winehq.org/wine/wine/-/merge_requests/1162

[PATCH 0/1] MR1260: kernel32/test: Fix sporadic process test failure.
by eric pouech (＠epo) 04 Nov '22

04 Nov '22

In attribute list test: - current test tries to ensure that a handle, valid in process' parent, hasn't been inherited - but nothing guarantees that a valid handle isn't present in child process with same value - so harden test to verify that the handle isn't the parent's pipe handle Signed-off-by: Eric Pouech <eric.pouech(a)gmail.com> -- https://gitlab.winehq.org/wine/wine/-/merge_requests/1260

[PATCH 0/2] MR1258: cmd: Consider only first argument as console title in "start".
by Nikolay Sivov (＠nsivov) 04 Nov '22

04 Nov '22

These patches are meant to fix batch files that are using quoted arguments like this: start /D "%~dp0" game.exe %* cmd adds extra quotes around directory path, assuming it's a console title. Later this does not work with start.exe. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/1258

[PATCH v6 0/2] MR1182: ntdll: Add CFI unwind info to __wine_syscall_dispatcher (i386).
by Jinoh Kang (＠iamahuman) 04 Nov '22

04 Nov '22

This change is adding DWARF (CFI) unwind information to the hand-written assembly of the `__wine_syscall_dispatcher` function. This enables unwinding through the dispatcher from the Linux stack into (and through) the Windows stack. The general idea is that the `syscall_frame` struct contains the content of the callee-save registers before the function call (in particular the stack pointer and the return address). At any point of the execution, we have a pointer into the `syscall_frame` in $ebx, $ecx, $ebp, or $esp. For the CFI codes the general idea is that we are defining the computations of the callee-save registers based on the `syscall_frame` using DWARF’s `breg` instruction, rather than relative to CFA. cc/ @florian-kuebler -- v6: ntdll: Add CFI unwind info to __wine_syscall_dispatcher (i386). ntdll: Move CFI helper macros out of signal_x86_64.c. https://gitlab.winehq.org/wine/wine/-/merge_requests/1182
