[PATCH v4 0/1] MR3288: gdiplus: Clip polygons before drawing them
by David Kahurani (＠kahurani) 15 Jul '23

15 Jul '23

Validate user data before passing it to PolyDraw. The program in the bug requests to draw figures outrageously outside the DC's region after presumably, some uninitialized values happen as a result of a missing font. Native gdiplus seems to handle this gracefully so we probably also should.

[PATCH v2 0/1] MR3313: gdiplus/tests: Fix mangled test output when dumping data in hex format.
by Jeffrey Smith (＠whydoubt) 15 Jul '23

Some tests in gdiplus output hex-formatted data chunks, but it is very hard to read EXAMPLE BEFORE FIX: ``` image.c:4831: Test marked todo: 16: data should match image.c:4837: 40image.c:4837: 40image.c:4837: 40image.c:4837: 40image.c:4837: 40image.c:4837: 40image.c:4837: 80i mage.c:4837: 80image.c:4837: 80image.c:4837: 80image.c:4837: 80image.c:4837: 80image.c:4837: 40image.c:4837: 40im age.c:4837: 40image.c:4837: 40image.c:4837: 40image.c:4837: 40image.c:4837: 40image.c:4837: 40image.c:4837: 40ima ge.c:4837: 40image.c:4837: 40image.c:4837: 40image.c:4838: ``` EXAMPLE AFTER FIX: ``` image.c:4802: Test marked todo: 16: data should match image.c:4804: 40 40 40 40 40 40 80 80 80 80 80 80 40 40 40 40 40 40 40 40 40 40 40 40 ``` -- v2: gdiplus/tests: Fix mangled test output when dumping data in hex format. https://gitlab.winehq.org/wine/wine/-/merge_requests/3313

[PATCH v2 0/1] MR3341: ntdll: Fix restoring X16 and X17 in ARM64 syscall dispatcher.
by Jinoh Kang (＠iamahuman) 15 Jul '23

15 Jul '23

Today, NtContinue() on ARM64 does not restore X16 and X17 from the context. This is because the values for X16 and X17 are overwritten when the current thread returns to the "user mode" (PE side) via __wine_syscall_dispatcher, which in turn uses them as scratch registers for restoring SP and PC respectively. We cannot avoid using scratch registers when restoring SP and PC. This is because ARMv8 does not have an unprivileged (EL0) instruction that loads SP and PC from memory or non-GPR architectural state. Fix this by making ARM64 __wine_syscall_dispatcher perform a full context restore via raise(SIGUSR2) when NtContinue() is used. Since raising a signal is quite expensive, it should be done only when necessary. To achieve this, split the ARM64 syscall dispatcher's returning behaviour into a fast path (that does not involve signals) and a slow path (that involves signals): - If CONTEXT_INTEGER is not set, the dispatcher takes the fast path: the X16 and X17 registers are clobbered as usual. - If X16 == PC and X17 == SP, the dispatcher also takes the fast path: it can safely use X16 and X17 without corrupting the register values, since those two registers already have the desired values. This fast path is used in call_user_apc_dispatcher(), call_user_exception_dispatcher(), and call_init_thunk(). - Otherwise, the dispatcher takes the slow path: it raises SIGUSR2 and does full context restore in the signal handler. -- v2: ntdll: Fix restoring X16 and X17 in ARM64 syscall dispatcher. https://gitlab.winehq.org/wine/wine/-/merge_requests/3341

[PATCH 0/1] MR3340: winegcc: Enable SafeSEH only on i386.
by Jinoh Kang (＠iamahuman) 15 Jul '23

SafeSEH is not applicable to architectures other than i386. This fixes compiling with the clang ARM assembler, which cannot parse ".def @feat.00" since "@" is parsed as the start of a line comment. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/3340
