ipcz: Fix nullptr deref in bridge bypass Bridge bypass logic assumes that bridge edges only get reset upon bypass completion. This isn't true if a node is forcibly disconnected (e.g. due to subprocess termination) and the resulting route teardown on one thread races with bridge bypass on another. Since forced route teardown cleans up all the same objects and more, we can simply terminate bridge bypass early in such cases.

ChromiumChromium is an open-source browser project that aims to build a safer, faster, and more stable way for all users to experience the web.
The project's web site is https://www.chromium.org.
To check out the source code locally, don't use git clone! Instead, follow the instructions on how to get the code.
Documentation in the source is rooted in docs/README.md.
Learn how to Get Around the Chromium Source Code Directory Structure .
For historical reasons, there are some small top level directories. Now the guidance is that new top level directories are for product (e.g. Chrome, Android WebView, Ash). Even if these products have multiple executables, the code should be in subdirectories of the product.
