How to contribute to syzkaller
Guidelines
If you want to contribute to the project, feel free to send a pull request.
Before sending a pull request you need to sign Google CLA (if you don't a bot will ask you to do that) and add yourself to AUTHORS/CONTRIBUTORS files (in case this is your first pull request to syzkaller).
Some guildelines to follow:
- Commit messages should follow the following template:
package: one-line description
<empty line>
Extended multi-line description that includes
the problem you are solving and how it is solved.
package
is the package/tool this commit changes
(look at examples in the commit history)
- The pull request text is mostly irrelevant
- Run
make presubmit
and ensure that it passes before sending a PR. It may require some additional packages to be installed (trysudo make install_prerequisites
) - Rebase your pull request onto the master branch before submitting
- If you're asked to add some fixes to your pull requested, please squash the new commits with the old ones
What to work on
Extending/improving system call descriptions is always a good idea.
Unassigned issues from the bug tracker are worth doing, but some of them might be complicated.
If you want to work on something non-trivial, please briefly describe it on the syzkaller@googlegroups.com mailing list first, so that there is agreement on high level approach and no duplication of work between contributors.
How to create a pull request
- First, you need an own git fork of syzkaller repository. Nagivate to github.com/google/syzkaller and press
Fork
button in the top-right corner of the page. This will createhttps://github.com/YOUR_GITHUB_USERNAME/syzkaller
repository. - Checkout main syzkaller repository if you have not already. To work with
go
command the checkout must be under$GOPATH
. The simplest way to do it is to rungo get github.com/google/syzkaller
, this will checkout the repository in$GOPATH/src/github.com/google/syzkaller
. - Then add your repository as an additional origin:
cd $GOPATH/src/github.com/google/syzkaller
git remote add my-origin https://github.com/YOUR_GITHUB_USERNAME/syzkaller.git
git fetch my-origin
git checkout -b my-branch master
This adds git origin my-origin
with your repository and checks out new branch my-branch
based on master
branch.
- Change/add files as necessary.
- Commit changes locally. For this you need to run
git add
for all changed files, e.g.git add sys/linux/sys.txt
. You can rungit status
to see what files were changed/created. When all files are added (git status
shows no files inChanges not staged for commit
section and no relevant files inUntracked files
section), rungit commit
and enter commit description in your editor. - Push the commit to your fork on github with
git push my-origin my-branch
. - Nagivate to github.com/google/syzkaller and you should see green
Compare & pull request
button, press it. Then pressCreate pull request
. Now your pull request should show up on pull requests page. - If you don't see
Create pull request
button for any reason, you can create pull request manually. For that nagivate to pull requests page, pressNew pull request
, thencompare across forks
and choosegoogle/syzkaller
/master
as base andYOUR_GITHUB_USERNAME/syzkaller
/my-branch
as compare and pressCreate pull request
. - If you decided to rebase commits in
my-branch
(e.g. to rebase them onto updated master) after you created a pull-request, you will need to do a force push:git push -f my-origin my-branch
.
