commit b76fc28533 upstream.
Stable_kernel_rules should point submitters of network stable patches to the
netdev_FAQ.txt as requests for stable network patches should go to netdev
first.

Everything you ever wanted to know about Linux -stable releases.

Rules on what kind of patches are accepted, and which ones are not, into the
|
|
"-stable" tree:
|
|
|
|
- It must be obviously correct and tested.
|
|
- It cannot be bigger than 100 lines, with context.
|
|
- It must fix only one thing.
|
|
- It must fix a real bug that bothers people (not a, "This could be a
|
|
problem..." type thing).
|
|
- It must fix a problem that causes a build error (but not for things
|
|
marked CONFIG_BROKEN), an oops, a hang, data corruption, a real
|
|
security issue, or some "oh, that's not good" issue. In short, something
|
|
critical.
|
|
- Serious issues as reported by a user of a distribution kernel may also
|
|
be considered if they fix a notable performance or interactivity issue.
|
|
As these fixes are not as obvious and have a higher risk of a subtle
|
|
regression they should only be submitted by a distribution kernel
|
|
maintainer and include an addendum linking to a bugzilla entry if it
|
|
exists and additional information on the user-visible impact.
|
|
- New device IDs and quirks are also accepted.
|
|
- No "theoretical race condition" issues, unless an explanation of how the
|
|
race can be exploited is also provided.
|
|
- It cannot contain any "trivial" fixes in it (spelling changes,
|
|
whitespace cleanups, etc).
|
|
- It must follow the Documentation/SubmittingPatches rules.
|
|
- It or an equivalent fix must already exist in Linus' tree (upstream).
|
|
|
|
|
|
Procedure for submitting patches to the -stable tree:
|
|
|
|
- If the patch covers files in net/ or drivers/net please follow netdev stable
|
|
submission guidelines as described in
|
|
Documentation/networking/netdev-FAQ.txt
|
|
- Send the patch, after verifying that it follows the above rules, to
|
|
stable@vger.kernel.org. You must note the upstream commit ID in the
|
|
changelog of your submission, as well as the kernel version you wish
|
|
it to be applied to.
|
|
- To have the patch automatically included in the stable tree, add the tag
|
|
Cc: stable@vger.kernel.org
|
|
in the sign-off area. Once the patch is merged it will be applied to
|
|
the stable tree without anything else needing to be done by the author
|
|
or subsystem maintainer.
|
|
- If the patch requires other patches as prerequisites which can be
|
|
cherry-picked than this can be specified in the following format in
|
|
the sign-off area:
|
|
|
|
Cc: <stable@vger.kernel.org> # 3.3.x: a1f84a3: sched: Check for idle
|
|
Cc: <stable@vger.kernel.org> # 3.3.x: 1b9508f: sched: Rate-limit newidle
|
|
Cc: <stable@vger.kernel.org> # 3.3.x: fd21073: sched: Fix affinity logic
|
|
Cc: <stable@vger.kernel.org> # 3.3.x
|
|
Signed-off-by: Ingo Molnar <mingo@elte.hu>
|
|
|
|
The tag sequence has the meaning of:
|
|
git cherry-pick a1f84a3
|
|
git cherry-pick 1b9508f
|
|
git cherry-pick fd21073
|
|
git cherry-pick <this commit>
|
|
|
|
- The sender will receive an ACK when the patch has been accepted into the
|
|
queue, or a NAK if the patch is rejected. This response might take a few
|
|
days, according to the developer's schedules.
|
|
- If accepted, the patch will be added to the -stable queue, for review by
|
|
other developers and by the relevant subsystem maintainer.
|
|
- Security patches should not be sent to this alias, but instead to the
|
|
documented security@kernel.org address.
|
|
|
|
|
|
Review cycle:
|
|
|
|
- When the -stable maintainers decide for a review cycle, the patches will be
|
|
sent to the review committee, and the maintainer of the affected area of
|
|
the patch (unless the submitter is the maintainer of the area) and CC: to
|
|
the linux-kernel mailing list.
|
|
- The review committee has 48 hours in which to ACK or NAK the patch.
|
|
- If the patch is rejected by a member of the committee, or linux-kernel
|
|
members object to the patch, bringing up issues that the maintainers and
|
|
members did not realize, the patch will be dropped from the queue.
|
|
- At the end of the review cycle, the ACKed patches will be added to the
|
|
latest -stable release, and a new -stable release will happen.
|
|
- Security patches will be accepted into the -stable tree directly from the
|
|
security kernel team, and not go through the normal review cycle.
|
|
Contact the kernel security team for more details on this procedure.
|
|
|
|
Trees:
|
|
|
|
- The queues of patches, for both completed versions and in progress
|
|
versions can be found at:
|
|
http://git.kernel.org/?p=linux/kernel/git/stable/stable-queue.git
|
|
- The finalized and tagged releases of all stable kernels can be found
|
|
in separate branches per version at:
|
|
http://git.kernel.org/?p=linux/kernel/git/stable/linux-stable.git
|
|
|
|
|
|
Review committee:
|
|
|
|
- This is made up of a number of kernel developers who have volunteered for
|
|
this task, and a few that haven't.
