Reason for revert: Beaking compile step in linux-libfuzzer-asan-rel Original change's description: > [Windows] Remove various uses of the windows.h header. > > This CL removes some uses of the windows.h header in the sandbox and > replaces them with windows_types.h or base code. This also includes > some general clean up such as removing naked memory allocations. > > Bug: 1270309 > Change-Id: I66e85a79704f755e7505d02356926a6773f52e10 > Reviewed-on: https://chromium-review.googlesource.com/c/chromium/src/+/3289994 > Reviewed-by: Will Harris <wfh@chromium.org> > Commit-Queue: James Forshaw <forshaw@chromium.org> > Cr-Commit-Position: refs/heads/main@{#943376} Bug: 1270309 Change-Id: I278efa02eff4e1c5a3e96b135bcac5c5fd1610d6 No-Presubmit: true No-Tree-Checks: true No-Try: true Reviewed-on: https://chromium-review.googlesource.com/c/chromium/src/+/3292829 Bot-Commit: Rubber Stamper <rubber-stamper@appspot.gserviceaccount.com> Commit-Queue: Renato Silva <rrsilva@google.com> Owners-Override: Renato Silva <rrsilva@google.com> Cr-Commit-Position: refs/heads/main@{#943476} NOKEYCHECK=True GitOrigin-RevId: 11a6a62ad060670afc265c71ee0d4262c02c9567
This directory contains platform-specific sandboxing libraries. Sandboxing is a technique that can improve the security of an application by separating untrustworthy code (or code that handles untrustworthy data) and restricting its privileges and capabilities.
Each platform relies on the operating system's process primitive to isolate code into distinct security principals, and platform-specific technologies are used to implement the privilege reduction. At a high-level:
mac/ uses the Seatbelt sandbox. See the detailed design for more.linux/ uses namespaces and Seccomp-BPF. See the detailed design for more.win/ uses a combination of restricted tokens, distinct job objects, alternate desktops, and integrity levels. See the detailed design for more.Built on top of the low-level sandboxing library is the //sandbox/policy component, which provides concrete policies and helper utilities for sandboxing specific Chromium processes and services. The core sandbox library cannot depend on the policy component.
