Lunatik v4.0

What's Changed

Updated Lua to v5.5

Lunatik now embeds Lua 5.5, a major language release with significant improvements after years since 5.4.

Key enhancements include:

• External strings, allowing immutable strings to be stored outside Lua.
• Explicit global variable declarations to reduce bugs from accidental globals.
• More compact arrays with up to ~60% memory savings for large tables.
• Incremental major garbage collection, reducing pause times and improving responsiveness.
• Read-only for loop variables and other language refinements.
• New utility features such as table.create, improved UTF-8 support.
• See more on the official Lua 5.5 release highlights.

Added luahid module (HID devices)

New binding for HID devices, including example scripts.
(Developed by @qrsikno2 – GSoC 2025)

Added luacpu module (per-CPU operations)

Provides per-CPU operations and CPU statistics export.
(Developed by @endersonmaia)

Added UNIX Domain Sockets support (AF_UNIX / AF_LOCAL)

Available via luasocket.

Added SKB resize support

Enables dynamic resizing of sk_buff (available via luadata).
(Developed by @abhijeetw035 based on @ArifAlam's draft)

Introduced high-level RAW socket API (AF_PACKET)

Simplified and standardized RAW socket handling.
(Developed by @sneaky-potato)

Added POSIX signals API

Support for signal delivery.
(Developed by @Physic69)

Netfilter hooks now expose network interface index (ifindex)

(Developed by @carloslack)

64-bit integer support on 32-bit platforms

Enables correct use of time APIs (e.g., on RAMIPS).

Improved error messages

(Developed by @abhijeetw035)

Fixed many bugs

• page fault and memory leaks on luacrypto_{aead, skcipher}
• deref SKB after running callback on luanetfilter and luaxtable
