Subject: [PATCH 067/201] mdadm: Change main repository to Github
Now github will be used for tracking mdadm, adjust README.md.
Daily routines will be automated on Github, there is not need to
decribe them.
Adjust release process, it must be published to both repositories.

-We don't have CI testing yet, so all those steps must be performed manually:
-- Style check with [checkpatch](https://docs.kernel.org/dev-tools/checkpatch.html):
-
- This is the current code style follows. We are not strict to all rules. It must be run
- by **checkpatch --no-tree**, see README.md.
-
-- [Commit style](https://www.kernel.org/doc/html/v4.10/process/submitting-patches.html):
-
- It doesn't need to be followed as strictly as is in kernel but changes should be logically
- separated. Submitter should care at least to mention "It is used in next patches" if unused
- externs/files are added in patch. We love: *Reported-by:*, *Suggested-by:*, *Fixes:* tags.
-
-- Compilation, ideally on various gcc versions.
-- Mdadm test suite execution.
-- Consider requesting new tests from submitter, especially for new functionalities.
-- Ensure that maintainer *sign-off* is added, before pushing.

Assuming that maintainer is certain that release is safe, following steps must be done:
-- Update versions strings in release commit, please refer to previous releases for examples.
+- Make and push release commit:

+# Questions and Support
+
+This Github site is **not** right place to ask if your are looking for:
+- support from Linux Raid Community;
+- support with kernel issues;
+
+This is the place where development of mdadm application is done. Please, do not use for
+looking for support. You should always ask on [Mailing List](https://lore.kernel.org/linux-raid/).
+
+Please use issues if you have confirmation that issue you are experiencing is related to mdadm
+components:
+- mdadm;
+- mdmon;
+- raid6check;
+- swap_super;
+- test_stripe;
+- systemd services ( see systemd/);
+- udev rules;
+- manual pages (including md.man)
+
+For example:
+- mdadm issues (e.g segfaults, memory leaks, crashes, bad communication with MD driver);
+- feature requests for mdadm;
+- suggestions or minor fixes requested (e.g. better error messages);
+
+Generally, if you are not sure it is better to ask on
+[Mailing List](https://lore.kernel.org/linux-raid/) first.
-It is maintained similarly to kernel, using *mailing list*. Patches must be send through email.
-Please familiarize with general kernel
-[submitting patches](https://www.kernel.org/doc/html/v4.17/process/submitting-patches.html)
-documentation. Formatting, tags and commit message guidelines applies to **mdadm**.
+# How to Contribute
-## Sending patches step-by-step
+Effective immediately [Github](https://github.com/md-raid-utilities/mdadm) is the primary
+location for **mdadm**. Use pull request to contribute.
-To maximize change of patches being taken, follow this instruction when submitting:
+It was originally hosted on [kernel.org](https://kernel.org/). You can access the old repository
+[here](https://git.kernel.org/pub/scm/utils/mdadm/mdadm.git).
-1. Create possibly logically separated commits and generate patches:
+Patches sent through Mailing list are accepted but Github is preferred. Sent then to ML only
+if you cannot use Github. Please add "mdadm:" to the subject to allow automation to create Github
+Pull Request and run checks.
- Use ``git format-patch --cover-letter --signoff -v <nr>`` to create patches:
- * ``--cover-letter`` can be skipped if it is only one patch;
- * ``--signoff`` adds sign-off tag;
- * ``-v <nr>`` indicates review revision number, sender should increment it before resending.
+**NOTE:** Maintainers may ask you to send RFC to mailing list if the proposed code requires
+consultation with kernel developers.
-2. Check style of every patch with kernel
- [checkpatch](https://docs.kernel.org/dev-tools/checkpatch.html) script:
+Kernel coding style is used. Please familiarize with general kernel
+[submitting patches](https://www.kernel.org/doc/html/v4.17/process/submitting-patches.html)
+documentation. Formatting, tags and commit message guidelines applies to **mdadm**.
- It is important to keep same coding style that is why in **mdadm**
- [kernel coding style](https://www.kernel.org/doc/html/v4.10/process/coding-style.html)
- is preferred. ``checkpath --no-tree <patch_file>`` can be used to verify patches.
- Following checkpatch issues can be ignored:
- - New typedefs.
- - comparing with *True/False*.
- - kernel *MAINTAINERS* file warning.
- - *extern* keyword in headers.
+[Checkpatch](https://docs.kernel.org/dev-tools/checkpatch.html) script is run on
+every patch in pull request so be sure that your commits are not generating
+issues. There are some excludes, so the best is to follow github checkpatch action result.
-3. Send patches using ``git send-mail --to=linux-raid@vger.kernel.org <cover-letter> <patch1> <patch2> (...)``
+Pull Request are closed by `Rebase and Merge` option, so it requires to keep every commit
+meaningful. Kernel style requires that. The review changes must be pushed with **push --force**
+to the chosen branch, then Pull Request will be automatically updated.
-# Maintainers
+# Maintainers of mdadm repository on kernel.org
-It is good practice to add **mdadm maintainers** to recipients for patches:
+If there are differences between github and kernel.org, please contact kernel.org mdadm maintainers:
- Jes Sorensen <jes@trained-monkey.org>;
- Mariusz Tkaczyk <mariusz.tkaczyk@linux.intel.com>;
-Adding **MD maintainers** could be reasonable, especially if patches may affect MD driver:
-
-- Song Liu <song@kernel.org>;
-- Yu Kuai <yukuai3@huawei.com>;
-
-# Reviewers
-
-**mdadm** utility is not part of kernel tree, so there is no certificated *Reviewers* list. Everyone
-can comment on mailing list, last decision (and merging) belongs to maintainers.
-
# Minimal supported kernel version
We do not support kernel versions below **v3.10**. Please be aware that maintainers may remove

Subject: [PATCH 161/201] imsm: add read OROM form ACPI UEFI tables
OROM - IMSM hardware capabilities
EFI vars depends on userspace, they need to be mounted to be accessible.
Sporadic problems have been observed with availability at an early
assemble stage. It is not possible to fully synchronize EFI vars mounts
with udev rules processing.
For the reason above, read of IMSM OROM from ACPI tables as secondary
option is added. This method will be used for SATA and VMD family
controllers.
ACPI tables are generated by sysfs, earlier in the boot process, before
the stage of RAID assembly. The way of loading OROM via EFI vars is
retained, ACPI tables will be a backup way.
Two paths will be maintained, because IMSM hardware capabilities are
necessary for RAID assembly during booting, so access to them must be
provided.

Subject: [PATCH 162/201] imsm: get bus from VMD driver directory
Enumeration of VMD child devices is started early, kernel is not waiting
for VMD enumeration to finish. It causes that:
/sys/bus/pci/drivers/vmd/{dev}/domain/device link might be not yet ready.
With PCI gen5 devices we can observe that mdadm is failing to start IMSM
raid arrays because of that. In that case, it needs to find bus path
manually.
Look for bus device in VMD driver directory if realpath() failed with
ENOENT.

Subject: [PATCH 166/201] imsm: add IMSM_OROM_CAPABILITIES_TPV to nvme orom
Add it to avoid excluding. It has some value for users even if it is
always true for nvme virtual orom.
Rework detail-platform printing code, move printing 3rd party nvmes
to print_imsm_capability (as it should be), but keep it meaningful
only for nvme controllers (NVME and VMD hba types). Pass whole
orom_entry instead of orom there.
Squash code responsible for printing NVME and VMD hbas.

Subject: [PATCH 168/201] imsm: save checkpoint prior to exit
If reshape (eg. chunksize migration) is gracefully stopped via SIGTERM
the checkpoint is not saved and reshape cannot be resumed due to "data
being present in copy area". This is because UNIT_SRC_NORMAL isn't set
if SIGTERM occurred.
Move SIGTERM handling at the end of the loop to allow saving checkpoint
(and state) so reshapes can be properly resumed.

Subject: [PATCH 171/201] Incremental: support devnode in IncrementalRemove.
There are no reasons to keep this interface different than others.
Allow to use devnode but keep old way for backward compatibility.
Method is added to verify that only devnode or kernel name is used.

+# Dependencies
+
+The following packages are required for compilation:
+
+| RHEL | SLES | Debian/Ubuntu |
+| :---: | :---: | :---: |
+| `pkgconf` | `pkg-config` | `pkg-config` |
+| `gcc` | `gcc` | `gcc` |
+| `make` | `make` | `make` |
+| `libudev-devel` | `libudev-devel` | `libudev-dev` |
+
+# Compiling mdadm
+
+Run `make` command to compile mdadm.
+
+Specifying more jobs e.g. `make -j4` can decrease compilation time significantly.
+
+Various values can be specified for the `CXFLAGS` variable to customize the build process:
+- Run `make CXFLAGS=-ggdb` to include gdb debugging information.
+- Run `make CXFLAGS=-DDEBUG` to enable additional debug information through dprintf statements
+and call traces.
+- Run `make CXFLAGS=-DNO_LIBUDEV` to compile without `libudev`.
+
+To build with more than one option specified in `CXFLAGS`, separate each option with a space, e.g.
+`make CXFLAGS="-ggdb -DDEBUG"`.
+
+Additionally, the `EXTRAVERSION` variable can be set to build with user-friendly version label,
+useful when customizing mdadm builds or labeling some instance in between major releases,
+e.g. `make EXTRAVERSION="custom-label"`.
+
+# Installing mdadm
+
+Before installing mdadm, it is advised to uninstall vendor-provided packages (mdadm.deb, mdadm.rpm
+etc.) in order to avoid configuration issues.
+
+Run `make install` command to install mdadm. This command invokes the following targets:
+- `install-bin`
+- `install-man`
+- `install-udev`
+
+After installing mdadm, consider rebuilding initramfs to ensure the changes take effect.
+
+List of installation targets:
+- Run `make install-bin` to install the mdadm and mdmon binary files.
+- Run `make install-systemd` to install the systemd services.
+- Run `make install-udev` to install the udev rules.
+- Run `make install-man` to install the manual pages (`mdadm.8`, `md.4`, `mdadm.conf.5`,
+`mdmon.8`).
+
+The following targets are deprecated and should not be used:
+- `install-static`
+- `install-tcc`

Subject: [PATCH 174/201] mdadm/Grow: Update new level when starting reshape
Reshape needs to specify a backup file when it can't update data offset
of member disks. For this situation, first, it starts reshape and then
it kicks off mdadm-grow-continue service which does backup job and
monitors the reshape process. The service is a new process, so it needs
to read superblock from member disks to get information.
But in the first step, it doesn't update new level in superblock. So
it can't change level after reshape finishes, because the new level is
not right. So records the new level in the first step.

Subject: [PATCH 179/201] mdadm/tests: 07changelevels fix
There are five changes to this case.
1. remove testdev check. It can't work anymore and check if it's a
block device directly.
2. It can't change level and chunk size at the same time
3. Sleep more than 10s before check wait.
The test devices are small. Sometimes it can finish so quickly once
the reshape just starts. mdadm will be stuck before it waits reshape
to start. So the sync speed is limited. And it restores the sync speed
when it waits reshape to finish. It's good for case without backup
file.
It uses systemd service mdadm-grow-continue to monitor reshape
progress when specifying backup file. If reshape finishes so quickly
before it starts monitoring reshape progress, the daemon will be stuck
too. Because reshape_progress is 0 which means the reshape hasn't been
started. So give more time to let service can get right information
from kernel space.
But before getting these information. It needs to suspend array. At
the same time the reshape is running. The kernel reshape daemon will
update metadata 10s. So it needs to limit the sync speed more than 10s
before restoring sync speed. Then systemd service can suspend array
and start monitoring reshape progress.
4. Wait until mdadm-grow-continue service exits
mdadm --wait doesn't wait systemd service. For the case that needs
backup file, systemd service deletes the backup file after reshape
finishes. In this test case, it runs next case when reshape finishes.
And it fails because it can't create backup file because the backup
file exits.
5. Don't reshape from raid5 to raid1. It can't work now.

Subject: [PATCH 188/201] Mdmonitor: Fix startup with missing directory
Commit 0a07dea8d3b78 ("Mdmonitor: Refactor check_one_sharer() for
better error handling") introduced an issue, if directory /run/mdadm
is missing, monitor fails to start. Move the directory creation
earlier to ensure it is always created.

Subject: [PATCH 189/201] mdadm: add xmalloc.h
Move memory declaration helpers outside mdadm.h. They seems to be
useful so keep them but include separatelly. Rework them to not reffer
to Name[] declared internally in mdadm/mdmon.
This is first step to start decomplexing mdadm.h.

Subject: [PATCH 194/201] mdmonitor: Abandon custom configuration files
Operating system vendors are customizing mdmonitor service beacause
the default form is not satifying for them (expect SUSE). As a result,
support is complicated (maintainers have to check the system) and man page
is not detailed.
I propose to abandon custom configuration files via sysconfig and keep
it inside mdadm.conf only.
Detailed comment in service for OSV maintainers is added to help with
transition.

Subject: [PATCH 199/201] util: use only /dev directory in open_dev()
Previously, open_dev() tried to open device in two ways - using /dev and
/tmp directory. This method could be used by users which have no access
to /tmp directory (e.g. udev) and dev_open() fails which may affect many
processes. Remove try to open in /tmp directory.
