PipeASIO, an ASIO bridge for PipeWire on Linux (primarily for use with Wine), has been released in version v1.2.1.

This release focuses on stability and security: a thread leak, a use-after-free vulnerability, and a buffer overrun in the PipeWire output path have all been fixed. The audio thread now finally runs at the correct real-time priority.

Changed

• Wine integration probes now run under CTest with Linux-native unit tests, enabling comprehensive test coverage via ctest --test-dir build.

Fixed

• Real-time scheduling: The audio thread previously ran at normal priority, causing performance issues. Now properly mapped to SCHED_FIFO priority 77, with fallback handling for permission errors.
• Thread leak: Each audio_open call leaked a zombie thread. The initial data loop is now properly stopped and joined before bridge installation.
• Use-after-free vulnerability: Synchronous kAsioResetRequest handling could trigger crashes. The watcher state now uses reference counting and safer threading patterns.
• Buffer overrun: RT output writes exceeded PipeWire buffer capacity when the graph quantum was clamped. Writes are now capacity-checked in both 64-bit and WoW64 paths.
• Sample position wrapping: 64-bit counters wrapped every ~25 hours at 48 kHz. Counters now use atomic 64-bit storage, fixing both wraparound and torn reads.
