Though I have two thoughts related to "we have final say" and why it was there: Sometimes we get insane embargo requests, and Linus has wanted to go public ASAP. The wording was chosen to let reporters know that it is possible for issues that don't need to wait 7 days to not wait 7 days. For example, letting security@xxxxxxxxxx know about a flaw and then tell us to sit on it for 2 months until some public presentation, that's not going to happen. Additionally, we frequently make all network bugs immediately public, since the net subsystem tends to reject embargoes. So, maybe we could be more explicit about these cases? Or explicitly describe what "reasonable" means (it's only hinted at). -Kees -- Kees Cook Pixel Security -- To unsubscribe from this list: send the line "unsubscribe linux-doc" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
