Create github pull requests for the repo. More details are included below.
Before you send patches at all, make sure that each patch makes sense. In particular:
-
A given patch should not break anything, even if later patches fix the problems that it causes. The source tree should still work after each patch is applied. (This enables
git bisectto work best.) -
A patch should make one logical change. Don't make multiple, logically unconnected changes to disparate subsystems in a single patch.
-
A patch that adds or removes user-visible features should also update the appropriate user documentation or manpages.
The summary line of your commit should be in the following format:
<area>: <summary>
-
<area>:indicates the area of the ovn-kubernetes to which the change applies (often the name of a source file or a directory). You may omit it if the change crosses multiple distinct pieces of code. -
<summary>briefly describes the change.
The body of the commit message should start with a more thorough description of the change. This becomes the body of the commit message, following the subject. There is no need to duplicate the summary given in the subject.
Please limit lines in the description to 79 characters in width.
The description should include:
-
The rationale for the change.
-
Design description and rationale (but this might be better added as code comments).
-
Testing that you performed (or testing that should be done but you could not for whatever reason).
-
Tags (see below).
There is no need to describe what the patch actually changed, if the reader can see it for himself.
If the patch refers to a commit already in the ovn-kubernetes repository, please include both the commit number and the subject of the patch, e.g. 'commit 632d136c (ovn-k8s-overlay: Flush the IP address of physical interface)
The description ends with a series of tags, written one to a line as the last paragraph of the email. Each tag indicates some property of the patch in an easily machine-parseable manner.
Examples of common tags follow.
Signed-off-by: Author Name <author.name@email.address...>
Informally, this indicates that Author Name is the author or
submitter of a patch and has the authority to submit it under
the terms of the license. The formal meaning is to agree to
the Developer's Certificate of Origin (see below).
If the author and submitter are different, each must sign off.
If the patch has more than one author, all must sign off.
Signed-off-by: Author Name <author.name@email.address...>
Signed-off-by: Submitter Name <submitter.name@email.address...>
Co-authored-by: Author Name <author.name@email.address...>
Git can only record a single person as the author of a given
patch. In the rare event that a patch has multiple authors,
one must be given the credit in Git and the others must be
credited via Co-authored-by: tags. (All co-authors must also
sign off.)
Acked-by: Reviewer Name <reviewer.name@email.address...>
Reviewers will often give an Acked-by: tag to code of which
they approve. It is polite for the submitter to add the tag
before posting the next version of the patch or applying the
patch to the repository. Quality reviewing is hard work, so
this gives a small amount of credit to the reviewer.
Not all reviewers give Acked-by: tags when they provide
positive reviews. It's customary only to add tags from
reviewers who actually provide them explicitly.
Tested-by: Tester Name <reviewer.name@email.address...>
When someone tests a patch, it is customary to add a
Tested-by: tag indicating that. It's rare for a tester to
actually provide the tag; usually the patch submitter makes
the tag himself in response to an email indicating successful
testing results.
Tested-at: <URL>
When a test report is publicly available, this provides a way
to reference it. Typical <URL>s would be build logs from
autobuilders or references to mailing list archives.
Some autobuilders only retain their logs for a limited amount
of time. It is less useful to cite these because they may be
dead links for a developer reading the commit message months
or years later.
Reported-by: Reporter Name <reporter.name@email.address...>
When a patch fixes a bug reported by some person, please
credit the reporter in the commit log in this fashion. Please
also add the reporter's name and email address to the list of
people who provided helpful bug reports in the AUTHORS file at
the top of the source tree.
Fairly often, the reporter of a bug also tests the fix.
Occasionally one sees a combined "Reported-and-tested-by:" tag
used to indicate this. It is also acceptable, and more
common, to include both tags separately.
(If a bug report is received privately, it might not always be
appropriate to publicly credit the reporter. If in doubt,
please ask the reporter.)
Requested-by: Requester Name <requester.name@email.address...>
Suggested-by: Suggester Name <suggester.name@email.address...>
When a patch implements a request or a suggestion made by some
person, please credit that person in the commit log in this
fashion. For a helpful suggestion, please also add the
person's name and email address to the list of people who
provided suggestions in the AUTHORS file at the top of the
source tree.
(If a suggestion or a request is received privately, it might
not always be appropriate to publicly give credit. If in
doubt, please ask.)
Reported-at: <URL>
If a patch fixes or is otherwise related to a bug reported in
a public bug tracker, please include a reference to the bug in
the form of a URL to the specific bug, e.g.:
Reported-at: https://bugs.debian.org/743635
This is also an appropriate way to refer to bug report emails
in public email archives, e.g.:
Reported-at: http://openvswitch.org/pipermail/dev/2014-June/040952.html
VMware-BZ: #1234567
ONF-JIRA: EXT-12345
If a patch fixes or is otherwise related to a bug reported in
a private bug tracker, you may include some tracking ID for
the bug for your own reference. Please include some
identifier to make the origin clear, e.g. "VMware-BZ" refers
to VMware's internal Bugzilla instance and "ONF-JIRA" refers
to the Open Networking Foundation's JIRA bug tracker.
Fixes: 63bc9fb1c69f (“packets: Reorder CS_* flags to remove gap.”)
If you would like to record which commit introduced a bug being fixed,
you may do that with a “Fixes” header. This assists in determining
which OVS releases have the bug, so the patch can be applied to all
affected versions. The easiest way to generate the header in the
proper format is with this git command:
git log -1 --pretty=format:"Fixes: %h (\"%s\")" --abbrev=12 COMMIT_REF
Vulnerability: CVE-2016-2074
Specifies that the patch fixes or is otherwise related to a
security vulnerability with the given CVE identifier. Other
identifiers in public vulnerability databases are also
suitable.
If the vulnerability was reported publicly, then it is also
appropriate to cite the URL to the report in a Reported-at
tag. Use a Reported-by tag to acknowledge the reporters.
To help track the author of a patch as well as the submission chain, and be clear that the developer has authority to submit a patch for inclusion in openvswitch please sign off your work. The sign off certifies the following:
