This will make things -+easier on the maintainers. Not all of these guidelines matter for every -+trivial patch so apply some common sense. -+ -+Tips for patch submitters -+------------------------- -+ -+1. Always *test* your changes, however small, on at least 4 or -+ 5 people, preferably many more. -+ -+2. Try to release a few ALPHA test versions to the net. Announce -+ them onto the kernel channel and await results. This is especially -+ important for device drivers, because often that's the only way -+ you will find things like the fact version 3 firmware needs -+ a magic fix you didn't know about, or some clown changed the -+ chips on a board and not its name. (Don't laugh! Look at the -+ SMC etherpower for that.) -+ -+3. Make sure your changes compile correctly in multiple -+ configurations. In particular check that changes work both as a -+ module and built into the kernel. -+ -+4. When you are happy with a change make it generally available for -+ testing and await feedback. -+ -+5. Make a patch available to the relevant maintainer in the list. Use -+ ``diff -u`` to make the patch easy to merge. Be prepared to get your -+ changes sent back with seemingly silly requests about formatting -+ and variable names. These aren't as silly as they seem. One -+ job the maintainers (and especially Linus) do is to keep things -+ looking the same. Sometimes this means that the clever hack in -+ your driver to get around a problem actually needs to become a -+ generalized kernel feature ready for next time. -+ -+ PLEASE check your patch with the automated style checker -+ (scripts/checkpatch.pl) to catch trivial style violations. -+ See Documentation/process/coding-style.rst for guidance here. -+ -+ PLEASE CC: the maintainers and mailing lists that are generated -+ by ``scripts/get_maintainer.pl.`` The results returned by the -+ script will be best if you have git installed and are making -+ your changes in a branch derived from Linus' latest git tree. -+ See Documentation/process/submitting-patches.rst for details. -+ -+ PLEASE try to include any credit lines you want added with the -+ patch. It avoids people being missed off by mistake and makes -+ it easier to know who wants adding and who doesn't. -+ -+ PLEASE document known bugs. If it doesn't work for everything -+ or does something very odd once a month document it. -+ -+ PLEASE remember that submissions must be made under the terms -+ of the Linux Foundation certificate of contribution and should -+ include a Signed-off-by: line. The current version of this -+ "Developer's Certificate of Origin" (DCO) is listed in the file -+ Documentation/process/submitting-patches.rst. -+ -+6. Make sure you have the right to send any changes you make. If you -+ do changes at work you may find your employer owns the patch -+ not you. -+ -+7. When sending security related changes or reports to a maintainer -+ please Cc: security@kernel.org, especially if the maintainer -+ does not respond. Please keep in mind that the security team is -+ a small set of people who can be efficient only when working on -+ verified bugs. Please only Cc: this list when you have identified -+ that the bug would present a short-term risk to other users if it -+ were publicly disclosed. For example, reports of address leaks do -+ not represent an immediate threat and are better handled publicly, -+ and ideally, should come with a patch proposal. Please do not send -+ automated reports to this list either. Such bugs will be handled -+ better and faster in the usual public places. See -+ Documentation/admin-guide/security-bugs.rst for details. -+ -+8. Happy hacking. -+ -+Descriptions of section entries and preferred order -+--------------------------------------------------- -+ -+ M: *Mail* patches to: FullName <address@domain> -+ R: Designated *Reviewer*: FullName <address@domain> -+ These reviewers should be CCed on patches. -+ L: *Mailing list* that is relevant to this area -+ S: *Status*, one of the following: -+ Supported: Someone is actually paid to look after this. -+ Maintained: Someone actually looks after it. -+ Odd Fixes: It has a maintainer but they don't have time to do -+ much other than throw the odd patch in. See below.. -+ Orphan: No current maintainer [but maybe you could take the -+ role as you write your new code]. -+ Obsolete: Old code. Something tagged obsolete generally means -+ it has been replaced by a better system and you -+ should be using that. -+ W: *Web-page* with status/info -+ Q: *Patchwork* web based patch tracking system site -+ B: URI for where to file *bugs*. A web-page with detailed bug -+ filing info, a direct bug tracker link, or a mailto: URI. -+ C: URI for *chat* protocol, server and channel where developers -+ usually hang out, for example irc://server/channel. -+ P: Subsystem Profile document for more details submitting -+ patches to the given subsystem. This is either an in-tree file, -+ or a URI. See Documentation/maintainer/maintainer-entry-profile.rst -+ for details. -+ T: *SCM* tree type and location. -+ Type is one of: git, hg, quilt, stgit, topgit -+ F: *Files* and directories wildcard patterns. -+ A trailing slash includes all files and subdirectory files. -+ F: drivers/net/ all files in and below drivers/net -+ F: drivers/net/* all files in drivers/net, but not below -+ F: */net/* all files in "any top level directory"/net -+ One pattern per line. Multiple F: lines acceptable. -+ X: *Excluded* files and directories that are NOT maintained, same -+ rules as F:. Files exclusions are tested before file matches. -+ Can be useful for excluding a specific subdirectory, for instance: -+ F: net/ -+ X: net/ipv6/ -+ matches all files in and below net excluding net/ipv6/ -+ N: Files and directories *Regex* patterns. -+ N: [^a-z]tegra all files whose path contains tegra -+ (not including files like integrator) -+ One pattern per line. Multiple N: lines acceptable. -+ scripts/get_maintainer.pl has different behavior for files that -+ match F: pattern and matches of N: patterns. By default, -+ get_maintainer will not look at git log history when an F: pattern -+ match occurs. When an N: match occurs, git log history is used -+ to also notify the people that have git commit signatures. -+ K: *Content regex* (perl extended) pattern match in a patch or file. -+ For instance: -+ K: of_get_profile -+ matches patches or files that contain "of_get_profile" -+ K: \b(printk|pr_(info|err))\b -+ matches patches or files that contain one or more of the words -+ printk, pr_info or pr_err -+ One regex pattern per line. Multiple K: lines acceptable. -+ -+Maintainers List -+---------------- -+ -+.. note:: When reading this list, please look for the most precise areas -+ first.
