  "text": "Audit of Chromium's renderer-process security sandbox (repo chromium/chromium). 1) seccomp-BPF base policy for Linux: sandbox/policy/linux/bpf_base_policy_linux.cc/.h define class BPFBasePolicy (a bpf_dsl::Policy subclass). Its EvaluateSyscall() delegates to an underlying BaselinePolicy (sandbox/linux/seccomp-bpf-helpers/baseline_policy.h, class BaselinePolicy), which lives under sandbox/linux/ and provides the actual seccomp baseline. 2) Windows sandbox policy configuration: sandbox/win/src/sandbox_policy.h defines class TargetPolicy (line 263), the abstract interface with SetTokenLevel/SetJobLevel/GetConfig etc.; the concrete implementation is PolicyBase in sandbox/win/src/sandbox_policy_base.h. 3) Renderer launch sandbox configuration: content/browser/renderer_host/renderer_sandboxed_process_launcher_delegate.cc/.h. RendererSandboxedProcessLauncherDelegate::GetSandboxType() returns sandbox::mojom::Sandbox::kRenderer; the Win variant RendererSandboxedProcessLauncherDelegateWin::InitializeConfig() applies renderer-specific policy. 4) SandboxType enum and profile mappings: the enum is the mojom-generated Sandbox enum declared in sandbox/policy/mojom/sandbox.mojom (enum Sandbox { ... kRenderer ... }); sandbox/policy/sandbox_type.h/.cc provide the helper/mapping functions (IsUnsandboxedSandboxType, SetCommandLineFlagsForSandboxType, SandboxTypeFromCommandLine, StringFromUtilitySandboxType) that map sandbox types to profiles/command-line flags."
