Contributions to openEuler kernel project ========================================= Sign CLA -------- Before submitting any Contributions to openEuler, you have to sign CLA. See: https://openeuler.org/zh/cla.html https://openeuler.org/en/cla.html Steps of submitting patches --------------------------- 1. Compile and test your patches successfully. 2. Generate patches Your patches should be based on top of latest openEuler branch, and should use git-format-patch to generate patches, and if it's a patchset, it's better to use --cover-letter option to describe what the patchset does. Using scripts/checkpatch.pl to make sure there's no coding style issue. And make sure your patch follow unified openEuler patch format describe below. 3. Send patch to openEuler mailing list Use this command to send patches to openEuler mailing list: git send-email *.patch -to="firstname.lastname@example.org" --suppress-cc=all *NOTE*: that you must add --suppress-cc=all if you use git send-email, otherwise the email will be cced to the people in upstream community and mailing lists. *See*: How to send patches using git-send-email https://git-scm.com/docs/git-send-email 4. Mark "v1, v2, v3 ..." in your patch subject if you have multiple versions to send out. Use --subject-prefix="PATCH v2" option to add v2 tag for patchset. git format-patch --subject-prefix="PATCH v2" -1 Subject examples: Subject: [PATCH v2 01/27] fork: fix some -Wmissing-prototypes warnings Subject: [PATCH v3] ext2: improve scalability of bitmap searching 5. Upstream your kernel patch to kernel community is strongly recommended. openEuler will sync up with kernel master timely. 6. Sign your work - the Developer’s Certificate of Origin As the same of upstream kernel community, you also need to sign your patch. See: https://www.kernel.org/doc/html/latest/process/submitting-patches.html The sign-off is a simple line at the end of the explanation for the patch, which certifies that you wrote it or otherwise have the right to pass it on as an open-source patch. The rules are pretty simple: if you can certify the below: Developer’s Certificate of Origin 1.1 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ By making a contribution to this project, I certify that: (a) The contribution was created in whole or in part by me and I have the right to submit it under the open source license indicated in the file; or (b The contribution is based upon previous work that, to the best of my knowledge, is covered under an appropriate open source license and I have the right under that license to submit that work with modifications, whether created in whole or in part by me, under the same open source license (unless I am permitted to submit under a different license), as indicated in the file; or (c) The contribution was provided directly to me by some other person who certified (a), (b) or (c) and I have not modified it. (d) I understand and agree that this project and the contribution are public and that a record of the contribution (including all personal information I submit with it, including my sign-off) is maintained indefinitely and may be redistributed consistent with this project or the open source license(s) involved. then you just add a line saying: Signed-off-by: Random J Developer <email@example.com> using your real name (sorry, no pseudonyms or anonymous contributions.) Use unified patch format ------------------------ Reasons: 1. long term maintainability openEuler will merge massive patches. If all patches are merged by casual changelog format without a unified format, the git log will be messy, and then it's hard to figure out the original patch. 2. kernel upgrade We definitely will upgrade our openEuler kernel in someday, using strict patch management will alleviate the pain to migrate patches during big upgrade. 3. easy for script parsing Keyword highlighting is necessary for script parsing. Patch format definition ----------------------- [M] stands for "mandatory" [O] stands for "option" $category can be: bug preparation, bugfix, perf, feature, doc, other... If category is feature, then we also need to add feature name like below: category: feature feature: YYY (the feature name) If the patch is related to CVE or bugzilla, then we need add the corresponding tag like below (In general, it should include at least one of the following): CVE: $cve-id bugzilla: $bug-id Additional changelog should include at least one of the flollwing: 1) Why we should apply this patch 2) What real problem in product does this patch resolved 3) How could we reproduce this bug or how to test 4) Other useful information for help to understand this patch or problem The detail information is very useful for porting patch to another kenrel branch. Example for mainline patch: mainline inclusion [M] from $mainline-version [M] commit $id [M] category: $category [M] bugzilla: $bug-id [O] CVE: $cve-id [O] additional changelog [O] -------------------------------- original changelog Signed-off-by: $yourname <$firstname.lastname@example.org> [M] ($mainline-version could be mainline-3.5, mainline-3.6, etc...) Examples -------- mainline inclusion from mainline-4.10 commit 0becc0ae5b42828785b589f686725ff5bc3b9b25 category: bugfix bugzilla: 3004 CVE: NA The patch fixes a BUG_ON in the product: injecting single bit ECC error to memory before system boot use hardware inject tools, which cause a large amount of CMCI during system booting .

Thunderbird Installation Get English version Thunderbird from http://www.mozilla.org/ and install it on your system。 Download url: https://www.thunderbird.net/en-US/thunderbird/all/ 2. Settings 2.1 Use plain text format instead of HTML format Options -> Account Settings -> Composition & Addressing, do *NOT* select "Compose message in HTML format". 2.2 Editor Settings Tools->Options->Advanced->Config editor. - To bring up the thunderbird's registry editor, and set: "mailnews.send_plaintext_flowed" to "false". - Disable HTML Format: Set "mail.identity.id1.compose_html" to "false". - Enable UTF8: Set "prefs.converted-to-utf8" to "true". - View message in UTF-8: Set "mailnews.view_default_charset" to "UTF-8". - Set mailnews.wraplength to 9999 for avoiding auto-wrap Linux kernel ============ There are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. Please read Documentation/admin-guide/README.rst first. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. The formatted documentation can also be read online at: https://www.kernel.org/doc/html/latest/ There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
