Remove all DISALLOW_COPY_AND_ASSIGNs This replaces all remaining DISALLOW_COPY_AND_ASSIGN() instances with their expanded counterparts. The macro definitions and IWYU are left as a separate change. The former to prevent unintended large reverts and the latter is easier once all DISALLOW_ macros are gone.

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.
