x86: sysupgrade: explicitly rescan disk after writing partition table

2017-05-29T21:50:34+00:00

This should ensure that the kernel partition can be mounted in
platform_copy_config when its size has changed.

x86: sysupgrade: refactor platform_do_upgrade

2017-05-29T21:50:34+00:00

By returning early when no upgrade device can be found and handling the
SAVE_PARTITIONS=0 case differently, we can get rid of two levels of if.

x86: sysupgrade: move partition table change check to platform_check_image

2017-05-29T21:50:34+00:00

The staged sysupgrade will prevent us from using ask_bool in
platform_do_upgrade; therefore, the check is moved to platform_check_image.

x86: fix sysupgrades on disks with 4k block size

2017-01-25T07:13:15+00:00

Even when the disk uses 4k blocks, the partition table still uses units
of 512 byte sectors. Always use ibs=512 for the offsets

x86: generalize partition discovery for sysupgrade

2016-05-24T11:30:58+00:00

Generalize the partition discovery in sysupgrade in order to fix sysupgrade
and config backup/recovery on MMC block devices which use a different naming
scheme compared to mtdblock or sd* devices.

The change also adds the find applet to the ramdisk utilities so that upgrade
code can rely on it.

The commit is based on the initial submission by Russell Senior at
http://patchwork.ozlabs.org/patch/625440/ .

x86: fix platform_export_bootpart() for Xen virtual disks

2016-04-17T13:24:30+00:00

Virtual disk devices in a Xen virtual machine (DomU) can be /dev/xvda,
/dev/xvdb and so on with partitions like /dev/xdva1. Devices named like
this where not considered before. This resulted in a non working
sysupgrade, because the boot partition could not be found.

x86: preserve partition table on sysupgrade

2016-02-09T12:33:17+00:00

With this patch sysupgrade will write directly to the partitions
instead of to the main disk.  The UUID is copied from the image
to the MBR as well.  This prevents the mbr from being completely
overwritten and losing the partition table.  The -p option has
been added to maintain the original behavior and overwite the
entire disk with the new image.  Tests have been added to ensure
that the image partitions match up with the active partitions.
