Ryan Houdek 7047d08ca4 FEXInterpreter: Removes three static objects
These three objects are easy enough to move out of the static namespace.
They were causing atexit registrations for deallocating memory.

Removes three `atexit` registrations that contributes to crashing on
exit.

Tony Wasserka 0bff771c03 LibraryForwarding/vulkan: Redo definitions update
eb95a959bc (#5171) did not keep the interface
file in sync with the output of DefinitionExtract.py. Some definitions were
reordered in the Vulkan headers.

There also is no "conflict" about CUDA extensions; instead, the previous
update didn't reflect that the new headers fully hide beta extensions.

Ryan Houdek d7c2b8f513 FEXCore: Cleanup pointers structure
There's no longer a distinction between AArch64 and x86 and everything
effectively falls under "Common" now. This means flattening the entire
structure just cleans it up.

NFC. (Although instcountCI will update because of a couple pointer
offsets changing)

FEXCore: Fixes circular dependency with thunk callback

Ryan Houdek 817a927e31 FEXCore: Fixes circular dependency with thunk callback
Fixes crash in thunks that use callbacks, introduced in #5148.

The dispatcher would call the syscallhandler to get the VDSO thunk
callback. But due to reordering initialization, the VDSO thunk would
have not been loaded at that point. This would cause thunks that use
callbacks to crash with a nullptr exception.

Instead, defer the thunk callback pointer loading until the thread
starts executing, and load the pointer in to our thread state's pointer
struct instead.

Didn't get caught in my initial test sweep since I didn't run a Wine
game with thunks.

Ryan Houdek ac3cabec07 Relocations: Disable 6-byte size optimization in InsertGuestRIPMove
This wasn't handling negatives correctly which was causing xalia.exe to
assert. Disable for now rather than further changing logic, with a TODO that it
should get fixed in the future.

LinuxSyscalls/x32: Fixes fcntl assert
2026-01-07 11:31:13 -05:00
Ryan Houdek c7df064d58 LinuxSyscalls/x32: Fixes fcntl assert
Steam started taking advantage of newer fcntl commands, in particular
`F_CREATED_QUERY`. This was causing our fcntl handler for 32-bit
processes to assert out.

Fixes the handler so it passes all other fcntl commands forward, just
like the Linux kernel does. Splits the 32-bit handler to explicitly
ignore a handful of commands just like the Linux kernel.

Fixes an assert that Steam was hitting.

Billy Laws ece38a5411 WOW64: Lock the JIT context and block suspend during context operations
Prevent suspension when flushing thread state to the WOW64 context
during BTCpuSetContext as suspension itself performs a flush. If
suspension were to occur halfway through FlushThreadStateContext then
the fact that the WOW64 context has been dirtied would be missed and the
new context would be partially overwritten with stale data from the FEX
thread state. Additionally if the context were to be dirtied by
suspension at any point during context merging in BTCpuSetContext the
input context could be lost.

Fixes occasional crashes when starting AC4.

Billy Laws 8e9f593c39 Windows: Handle NtReadFile calls to RX protected RWX memory
Handling this safely requires blocking all compilation for the duration
of the read, as fault-based tracking doesn't work when wine's unix side
itself is the one performing the write into the RWX region (we cannot
catch unix faults).

Fixes a startup crash in Persona 5.

Billy Laws ec13e5d503 Windows: Use FrontendPtr for extra TLS space on WOW64/ARM64EC
We have run out of EmulatorData slots on ARM64EC, so introduce this for
less-frequently accessed TLS data for which the additional cost doesn't
matter.

Ryan Houdek 721ceecd70 ELFCodeLoader: Update the thread persona if it was passed in
Execstack enables `READ_IMPLIES_EXEC` and we were accidentally
decoupling our expected persona due to the reordering of initialization.

This was causing the smc-1-dynamic test to fail because it's testing
execstack and our VMA tracking wasn't returning read-write VMAs as
executable once these decoupled.

Easy fix.

Ryan Houdek 3728f5f178 Interpreter: Moves around the thread and ELF initialization code
This allows the context and parent thread objects to be created earlier,
allowing the VDSO and ELFCodeLoader mapping functions to have a thread
object for tracking memory mappings through the regular guest routines.

This means that we no longer need to do any form of deferred handling
for code caching as all the state is ready early in the initialization
process.

A little bit of care needed to be taken to ensure we still close the
ELFCodeLoader's FDs later and that VDSO unmapping happens before tearing
down the parent thread, but overall this is mostly just passing the
InternalThreadState object around as normal.

I couldn't find any functional regression from this change alongside
code caching, but it would be good for @neobrain to double check this.

FEX argument will no longer exist in `/proc/<pid>/cmdline` after this
PR. Ensure this tool still works.

After #5097 is merged, one can use regular `pidof` for Linux
applications, but this is still useful as it finds Wine applications
running with FEX as well.

Billy Laws e97b18e244 InvalidationTracker: Fix potential race when reprotecting RWX ranges
Theoretically, another thread could run after the reprotection but
before the invalidation, write some code and jump to it but end up
jumping to old code as the invalidation is yet to occur. Fix this by
locking the invalidation mutex, invalidating and only then reprotecting.
