Libraries

This repository also contains additional UEFI support common libraries shared by other projects in Acidanthera. The primary purpose of the library set is to provide supplemental functionality for Apple-specific UEFI drivers. Key features:

Apple disk image loading support

Apple keyboard input aggregation

Apple PE image signature verification

Apple UEFI secure boot supplemental code

Audio management with screen reading support

Basic ACPI and SMBIOS manipulation

CPU information gathering with timer support

Cryptographic primitives (SHA-256, RSA, etc.)

Decompression primitives (zlib, lzss, lzvn, etc.)

Helper code for ACPI reads and modifications

Higher level abstractions for files, strings, UEFI variables

Overflow checking arithmetics

PE image loading with no UEFI Secure Boot conflict

Plist configuration format parsing

PNG image manipulation

Text output and graphics output implementations

XNU kernel driver injection and patch engine

Early history of the codebase could be found in AppleSupportPkg and PicoLib library set by The HermitCrabs Lab.

OcGuardLib

This library implements basic safety features recommended for the use within the project. It implements fast safe integral arithmetics mapping on compiler builtins, type alignment checking, and UBSan runtime, based on NetBSD implementation.

The use of UBSan runtime requires the use of Clang compiler and -fsanitize=undefined argument. Refer to Clang documentation for more details.
