Change all files that depends on the existence of the deprecated global sources assignment filter to explicitly configure it by importing the deprecated_default_sources_assignment_filter.gni and calling set_sources_assignment_filter(). This is a preliminary step before removing the global assignment in //build/config/BUILDCONFIG.gn and incremental migration of those files from the deprecated feature. To verify, used a patched version of gn: https://gn-review.googlesource.com/c/gn/+/6401 And then ran: gn gen out/xxx | grep Filtering: | sort with and without the patch for all configuration (cross-compiling Windows on Linux). This is a followup of https://crrev.com/c/2418443 that missed some of the usages (as not all configuration were tested).

Sandbox Library
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.
