How to Submit Patches for ingress-node-firewall

Create github pull requests for the repo. More details are included below.

Before You Start

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 bisect to 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.

Commit Summary

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.

Commit Description

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)

Tags

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 cr
