Subject: [PATCH v3 4/7] Documentation/security-bugs: add linux-distros and oss-security sections

The existing information about CVE assignment requests and coordinated
disclosure fits much better in these new sections, since that's what these
lists are for.

Keep just a reminder in the security list section.

-Coordination
-------------
-
-Fixes for sensitive bugs, such as those that might lead to privilege
-escalations, may need to be coordinated with the private
-<linux-distros@...openwall.org> mailing list so that distribution vendors
-are well prepared to issue a fixed kernel upon public disclosure of the
-upstream fix. Distros will need some time to test the proposed patch and
-will generally request at least a few days of embargo, and vendor update
-publication prefers to happen Tuesday through Thursday. When appropriate,
-the security team can assist with this coordination, or the reporter can
-include linux-distros from the start. In this case, remember to prefix
-the email Subject line with "[vs]" as described in the linux-distros wiki:

-CVE assignment
---------------

-The security team does not normally assign CVEs, nor do we require them

-may delay the bug handling. If a reporter wishes to have a CVE identifier
-assigned ahead of public disclosure, they will need to contact the private
-linux-distros list, described above. When such a CVE identifier is known
-before a patch is provided, it is desirable to mention it in the commit
-message if the reporter agrees.

+
+Contacting the linux-distros list
+---------------------------------
+
+Fixes for particularly sensitive bugs (such as those that might lead to
+privilege escalations) may need to be coordinated with the private
+linux-distros mailing list (linux-distros@...openwall.org) so that
+distribution vendors are well prepared to release a fixed kernel as soon as
+possible after the public disclosure of the upstream fix.  This includes
+verifying the reported issue, testing proposed fixes, developing a fix (if
+none is known yet), and backporting to older kernels and other versions.
+
+The linux-distros list can also help with assigning a CVE for your issue.
+
+**Disclosure.** The linux-distros list has a strict policy of requiring
+reporters to post about the security issue on oss-security within 14
+calendar days of the list being contacted regardless of whether a patch is
+available or not.  It is therefore preferable that you don't send your
+initial bug report to the linux-distros list unless you already have a patch
+for the issue.
+
+**List rules.** The main rules to be aware of when contacting the
+linux-distros list are:
+
+* Don't post about issues that are already public. If your issue has a
+  public patch, but the security impact is not generally known, then you may
+  still post about it.
+
+* The submitter can suggest an embargo end-date, but as a rule, embargoes
+  should not be longer than 7 calendar days, or at most 14 calendar days in
+  exceptional cases. Keep in mind that vendors may prefer to release new
+  kernel packages and/or updates Tuesday through Thursday.
+
+* When the embargo ends, the issue must be disclosed immediately on the
+  oss-security list (see below).
+
+* Prefix your subject with the string "[vs]" to avoid getting rejected by
+  the spam filter.
+
+For the full list of rules, see:
+https://oss-security.openwall.org/wiki/mailing-lists/distros#list-policy-and-instructions-for-reporters
+
+**Confidentiality.** Please note that, as opposed to the security list, any
+and all material submitted to the list must be made public once the security
+issue is publicly disclosed, so please do not post information to the
+linux-distros list that cannot be made public.
+
+Contacting the oss-security list
+--------------------------------
+
+When your security issue is public, or you wish to make your issue public,
+you can write to the oss-security list (oss-security@...ts.openwall.com).
+This is a public list (anybody can subscribe and view the list archives) and
+it is not restricted to Linux kernel issues.
+
+The oss-security list typically does not assign CVEs or accept requests for
+CVE assignments.
+
+**List rules.** Please do not cross-post to other lists when writing to this
+list. Make sure to read the other list rules before posting:
+https://oss-security.openwall.org/wiki/mailing-lists/oss-security.
