Pull documentation update from Jonathan Corbet:
"A fairly normal cycle for documentation stuff. We have a new document
on perf security, more Italian translations, more improvements to the
memory-management docs, improvements to the pathname lookup
documentation, and the usual array of smaller fixes.
As is often the case, there are a few reaches outside of
Documentation/ to adjust kerneldoc comments"

Security bugs
|
|
=============
|
|
|
|
Linux kernel developers take security very seriously. As such, we'd
|
|
like to know when a security bug is found so that it can be fixed and
|
|
disclosed as quickly as possible. Please report security bugs to the
|
|
Linux kernel security team.
|
|
|
|
Contact
|
|
-------
|
|
|
|
The Linux kernel security team can be contacted by email at
|
|
<security@kernel.org>. This is a private list of security officers
|
|
who will help verify the bug report and develop and release a fix.
|
|
If you already have a fix, please include it with your report, as
|
|
that can speed up the process considerably. It is possible that the
|
|
security team will bring in extra help from area maintainers to
|
|
understand and fix the security vulnerability.
|
|
|
|
As it is with any bug, the more information provided the easier it
|
|
will be to diagnose and fix. Please review the procedure outlined in
|
|
admin-guide/reporting-bugs.rst if you are unclear about what
|
|
information is helpful. Any exploit code is very helpful and will not
|
|
be released without consent from the reporter unless it has already been
|
|
made public.
|
|
|
|
Disclosure and embargoed information
|
|
------------------------------------
|
|
|
|
The security list is not a disclosure channel. For that, see Coordination
|
|
below.
|
|
|
|
Once a robust fix has been developed, the release process starts. Fixes
|
|
for publicly known bugs are released immediately.
|
|
|
|
Although our preference is to release fixes for publicly undisclosed bugs
|
|
as soon as they become available, this may be postponed at the request of
|
|
the reporter or an affected party for up to 7 calendar days from the start
|
|
of the release process, with an exceptional extension to 14 calendar days
|
|
if it is agreed that the criticality of the bug requires more time. The
|
|
only valid reason for deferring the publication of a fix is to accommodate
|
|
the logistics of QA and large scale rollouts which require release
|
|
coordination.
|
|
|
|
While embargoed information may be shared with trusted individuals in
|
|
order to develop a fix, such information will not be published alongside
|
|
the fix or on any other disclosure channel without the permission of the
|
|
reporter. This includes but is not limited to the original bug report
|
|
and followup discussions (if any), exploits, CVE information or the
|
|
identity of the reporter.
|
|
|
|
In other words our only interest is in getting bugs fixed. All other
|
|
information submitted to the security list and any followup discussions
|
|
of the report are treated confidentially even after the embargo has been
|
|
lifted, in perpetuity.
|
|
|
|
Coordination
|
|
------------
|
|
|
|
Fixes for sensitive bugs, such as those that might lead to privilege
|
|
escalations, may need to be coordinated with the private
|
|
<linux-distros@vs.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:
|
|
<http://oss-security.openwall.org/wiki/mailing-lists/distros#how-to-use-the-lists>
|
|
|
|
CVE assignment
|
|
--------------
|
|
|
|
The security team does not normally assign CVEs, nor do we require them
|
|
for reports or fixes, as this can needlessly complicate the process and
|
|
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.
|
|
|
|
Non-disclosure agreements
|
|
-------------------------
|
|
|
|
The Linux kernel security team is not a formal body and therefore unable
|
|
to enter any non-disclosure agreements.
