OcSupportPkg
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.
Early history of the codebase could be found in AppleSupportPkg and PicoLib library set by The HermitCrabs Lab.
Features
- Apple PE image signature verification
- CPU information gathering
- Cryptographic primitives (SHA-256, RSA, etc.)
- Helper code for ACPI reads and modifications
- Higher level abstractions for files, strings, timers, variables
- Overflow checking arithmetics
- PE image loading with no UEFI Secure Boot conflict
- Plist configuration format parsing
- PNG image loading
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.
