Summary
This PR introduces native Go fuzzing (
go test -fuzz) for system configuration decoding and validation inpkg/unikontainers/urunc_config.go.This directly addresses part of #852 ("Add fuzzing and robustness testing") by establishing automated fuzz targets for core parsing functions.
Description of Changes
ParseUruncConfigBytes(data []byte) (*UruncConfig, error)inpkg/unikontainers/urunc_config.goto allow direct TOML parsing from byte slices without requiring disk file reads.TestParseUruncConfigBytesinpkg/unikontainers/urunc_config_test.goto verify valid TOML bytes parsing and graceful error handling on malformed bytes.FuzzLoadUruncConfig(f *testing.F)inpkg/unikontainers/urunc_config_test.gowith seed corpuses for valid TOML configurations, fuzzing TOML decoding and ensuringcfg.Map()invariants hold without panics.Related Issue
Closes #919
