Revert "[Windows] Add lock around AppContainer profile creation." This reverts commit 7b45bb70b483024adb7b939c6e9e2345504d7b65. Reason for revert: Possibly causing hangs on shutdown, see crbug.com/1307974 Original change's description: > [Windows] Add lock around AppContainer profile creation. > > This CL adds a named mutex around AppContainer profile creation. This > is to try and eliminate race conditions between multiple processes > using the same profile type. > > Bug: 1280214 > Change-Id: Ic8dbc4943c57ef2aa501d06edeb3c6b560055426 > Reviewed-on: https://chromium-review.googlesource.com/c/chromium/src/+/3509574 > Reviewed-by: Will Harris <wfh@chromium.org> > Commit-Queue: James Forshaw <forshaw@chromium.org> > Cr-Commit-Position: refs/heads/main@{#980677} Bug: 1280214 Change-Id: Ia6be11d83aa4e4375f8bce4e1f30f6a3bbab8e45 Reviewed-on: https://chromium-review.googlesource.com/c/chromium/src/+/3538085 Bot-Commit: Rubber Stamper <rubber-stamper@appspot.gserviceaccount.com> Reviewed-by: Will Harris <wfh@chromium.org> Commit-Queue: James Forshaw <forshaw@chromium.org> Cr-Commit-Position: refs/heads/main@{#983425} NOKEYCHECK=True GitOrigin-RevId: fbb9cce19d39cfe896b47c7c2bc1c26effcda42d
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.
