CAKE accepts overhead values that can make adjusted packet length arithmetic underflow. A negative effective length can wrap through unsigned arithmetic and become a large value.
Sorry, why are you posting more patches? You were told to stop yesterday. And you received an email which said: Here are a few ground rules which are frequently broken by newcomers: - You must wait at least 24 hours before posting a new version to give reviewers time to respond. This is a hard rule, no matter what your reason to repost is. - Each new version of your series should be a fresh / separate thread Add a https://lore.kernel.org/.. link to the previous version to the cover letter or changelog, instead of threading the submissions. - Until you gain experience submit one of two patches at a time, do not send multiple changes at once until some of your changes were accepted. This avoids reviewers having to provide the same feedback on multiple patches. - Avoid changing the subject of the changes or cover letter unless necessary, it breaks our patch tracking. - If you're submitting changes for issues discovered using automated tools - commit message should explain the discovery and testing process (for drivers explicitly mention that you don't have access to the device, it's not a blocker). You broke at least 2 of these already. If you keep ignoring direct maintainer feedback you will be banned.
