[isar-cip-core][PATCH v2 1/1] swupdate: Add option to use swupdate-handler-roundrobin


Quirin Gylstorff
 

From: Quirin Gylstorff <quirin.gylstorff@siemens.com>

The new SWUpdate round-robin handler is available under[1].
Add the Option `SWUPDATE_HANDLER_BOOT_HANDLER_CONFIG` to
set the source of the swupdate-handler-roundrobin configuration.

If another Lua handler should be used, set the variable
`SWUPDATE_USE_ROUND_ROBIN_HANDLER_REPO` to `0`. Add the alternative
handler to the repository and use the variable
`SWUPDATE_LUASCRIPT` to add the handler to the build.

-
- An `sw-description` file using these handlers may look like:
- software =
- {
- version = "0.1.0";
- images: ({
- filename = "rootfs.ext4";
- device = "sda4,sda5";
- type = "roundrobin";
- compressed = false;
- });
- files: ({
- filename = "vmlinuz";
- path = "vmlinuz";
- type = "kernelfile";
- device = "sda2,sda3";
- filesystem = "vfat";
- },
- {
- filename = "initrd.img";
- path = "initrd.img";
- type = "kernelfile";
- device = "sda2,sda3";
- filesystem = "vfat";
- });
- }
-
- The semantics is as follows: Instead of having a fixed target device,
- the 'roundrobin' image handler calculates the target device by parsing
- /proc/cmdline, matching the root=<device> kernel parameter against its
- 'device' attribute's list of devices, and sets the actual target
- device to the next 'device' attribute list entry in a round-robin
- manner. The actual flashing is done via chain-calling another handler,
- defaulting to the "raw" handler.
-
- The 'kernelfile' file handler reuses the 'roundrobin' handler's target
- device calculation by reading the actual target device from the same
- index into its 'device' attribute's list of devices. The actual placing
- of files into this partition is done via chain-calling another handler,
- defaulting to the "rawfile" handler.
-
- In the above example, if /dev/sda4 is currently booted according to
- /proc/cmdline, /dev/sda5 will be flashed and the vmlinuz and initrd.img
- files will be placed on /dev/sda3. If /dev/sda5 is booted, /dev/sda4
- will be flashed and the vmlinuz and initrd.img files are placed on
- /dev/sda2.
- In addition to "classical" device nodes as in this example, partition
- UUIDs as reported, e.g., by `blkid -s PARTUUID` are also supported.
- UBI volumes are supported as well by specifying a CSV list of
- ubi<number>:<label> items.
-
- Configuration is done via an INI-style configuration file located at
- /etc/swupdate.handler.ini or via compiled-in configuration (by
- embedding the Lua handler script into the SWUpdate binary via using
- CONFIG_EMBEDDED_LUA_HANDLER), the latter having precedence over the
- former. See the example configuration below.
- If uncommenting this example block, it will take precedence over any
- /etc/swupdate.handler.ini configuration file.
-
- The chain-called handlers can either be specified in the configuration,
- i.e., a static run-time setting, or via the 'chainhandler' property of
- an 'image' or 'file' section in the sw-description, with the latter
- taking precedence over the former, e.g.,
- ...
- images: ({
- filename = "rootfs.ext4";
- device = "sda4,sda5";
- type = "roundrobin";
- properties: {
- chainhandler = "myraw";
- };
- });
- ...
- Such a sw-description fragment will chain-call the imaginary "myraw"
- handler regardless of what's been configured in the compiled-in or the
- configuration file.
- When chain-calling the "rdiff_image" handler, its 'rdiffbase' property
- is subject to round-robin as well, i.e., the 'rdiffbase' property is
- expected to be a CSV list as for the 'device' property, and the actual
- 'rdiffbase' property value is calculated following the same round-robin
- calculation mechanism stated above prior to chain-calling the actual
- "rdiff_image" handler, e.g.,
- images: ({
- filename = "rootfs.ext4";
- type = "roundrobin";
- device = "sda4,sda5";
- properties: {
- chainhandler = "rdiff_image";
- rdiffbase="sda1,sda2";
- };
- });
- will set the 'rdiffbase' property to /dev/sda2 (/dev/sda1) if /dev/sda4
- (/dev/sda5) is the currently booted root file system according to
- /proc/cmdline parsing.
