Adrian Schmutzler 469e347f19 base-files: provide option to specify label MAC address in board.d
For many devices, MAC addresses cannot be retrieved via the
device tree alias.

To still provide the label MAC address for those, this implements
a second mechanism that will put the address into uci config.
Note that this stores the actual MAC address, whereas in DTS
we reference the bearing device.

This is based on the work of Rosy Song <rosysong@rosinson.com>

Adrian Schmutzler 0340718863 base-files: add function to retrieve label MAC address
To refer to the MAC address on a device's label, one can
specify the alias label-mac-device in the DTS which should
point to the bearer of the corresponding MAC address.

With the function get_mac_label, the user can retrieve then
retrieve this address and use it as a value that uniquely
identifies his device.

This is severely helpful for several downstream functionalities,
e.g. define MAC addresses of custom netifs or change the SSID to
be easily recognizable.

Rafał Miłecki f522047958 base-files: use JSON for storing firmware validation info
So far firmware validation result was binary limited: it was either
successful or not. That meant various limitations, e.g.:
1) Lack of proper feedback on validation problems
2) No way of marking firmware as totally broken (impossible to install)

This change introduces JSON for storing detailed validation info. It
provides a list of performed validation tests and their results. It
allows marking firmware as non-forceable (broken image that can't be
even forced to install).
Example:
{
        "tests": {
                "fwtool_signature": true,
                "fwtool_device_match": true
        },
        "valid": true,
        "forceable": true
}

Implementation is based on *internal* check_image bash script that:
1) Uses existing validation functions
2) Provides helpers for setting extra validation info

This allows e.g. platform_check_image() to call notify_check_broken()
when needed & prevent user from bricking a device.

Right now the new JSON info is used by /sbin/sysupgrade only. It still
doesn't make use of "forceable" as that is planned for later
development.

Further plans for this feature are:
1) Expose firmware validation using some new ubus method
2) Move validation step from /sbin/sysupgrade into "sysupgrade" ubus
   method so:
   a) It's possible to safely sysupgrade using ubus only
   b) /sbin/sysupgrade can be more like just a CLI

Paul Spooren 454021581f build: add buildinfo files for reproducibility
generate feeds.buildinfo and version.buildinfo in build dir after
containing the feed revisions (via ./scripts/feeds list -sf) as well as
the current revision of buildroot (via ./scripts/getver.sh).

With this information it should be possible to reproduce any build,
especially the release builds.

Usage would be to move feeds.buildinfo to feeds.conf and git checkout the
revision hash of version.buildinfo.

Content of feeds.buildinfo would look similar to this:

    src-git routing https://git.openwrt.org/feed/routing.git^bf475d6
    src-git telephony https://git.openwrt.org/feed/telephony.git^470eb8e
    ...

Content of version.buildinfo would look similar to this:

    r10203+1-c12bd3a21b

Without the exact feed revision it is not possible to determine
installed package versions.

Also rename config.seed to config.buildinfo to follow the recommended
style of https://reproducible-builds.org/docs/recording/

Klaus Kudielka ad62247800 base-files: improve lib/upgrade/common.sh
Recently, upgrade device autodetection has been added to the mvebu target.
This exposes some shortcomings of the generic export_bootdevice function,
e.g. on the Turris Omnia: export_bootdevice silently reports the root
partition to be the boot device. This makes the sysupgrade process fail at
several places.

Fix this by clearly distinguishing between /proc/cmdline arguments which
specify the boot disk, and those which specify the root partition. Only in
the latter case, strip off the partition, and do it consistently.
root=PARTUUID=<pseudo PARTUUID for MBR> (any partition) and root=/dev/*
(any partition) are accepted.

The root of the problem is that the *existing* export_bootdevice in
/lib/upgrade/common.sh behaves differently, if the kernel is booted with
root=/dev/..., or if it is booted with root=PARTUUID=...

In the former case, it reports back major/minor of the root partition,
in the latter case it reports back major/minor of the complete boot disk.

Targets, which boot with root=/dev/... *and* use export_bootdevice /
export_partdevice, have added workarounds to this behaviour, by specifying
*negative* increments to the export_partdevice function.

Consequently, those targets have to be adapted to use positive increments,
otherwise they are broken by the change to export_bootdevice.

Arthur Skowronek fc23bcdaa2 base-files: add service_stopped as a post stop hook
Purpose of these changes is to introduce a hook for post service
shutdown in a similar fashion to the existing hook service_started. I
found it to be useful to specify a hook that is called once the service
has been stopped and not before the service is stopped like the
stop_service hook does.

The concrete use case I have for this is that I'm running a binary that
takes over the hardware watchdog timer. Said binary unfortunately can
not use ubus directly to tell procd to hand over the watchdog timer so
this has to be done in the service file for the binary in question. In
order to support a clean handover of the watchdog timer back to procd,
the service init script has to dispatch the ubus invocation once the
binary in question has been stopped.

The callback function receives two arguments when called, the config

If no callback function is given, then the wrapper exits with the value
returned by uci_validate_section().

This also updates several init scripts to use the new wrapper function.

ex.:
  The U-Boot on Buffalo WXR-2533DHP checks existence and checksum of

492-try-auto-mounting-ubi0-rootfs-in-init-do_mounts.c.patch

to facilitate ubi rootfs automount. However the upstream kernel
also supports the means of booting from a fully custom ubi
partition name and ubi volume name via bootargs/kernel's cmdline
parameters:

ubi.mtd=mtd_partition_name
ubi.block=rootfs_volume_name

Luiz Angelo Daros de Luca 5cb1dce542 base-files: add sysupgrade -k to save list of pkgs
When '-k' is used, sysupgrade inserts into backup a new file
/etc/backup/installed_packages.txt which contains pkgname and origin (rom,
overlay, unknown) without touching rootfs.

It's mainly used to reinstall all extra packages:

 # opkg update
 # grep "\toverlay" /etc/backup/installed_packages.txt | cut -f1 | xargs -r opkg install
 # rm /etc/backup/installed_packages.txt

Luiz Angelo Daros de Luca 96392e5da4 base-files: add sysupgrade -o to save all overlay files
Add sysupgrade '-o' option in order to include all overlay files in
backup, except for those that are from packages but including files
listed in conffiles, sysupgrade.conf or /lib/upgrade/keep.d.

With '-u' option, it will skip files equals to /rom and conffiles that
were not changed.

Luiz Angelo Daros de Luca 20b23270b7 base-files: add sysupgrade -u to skip unchanged files
With '-u', for a file /aaa/bbb/ccc enlisted for backup,
it will only get into backup if /rom/aaa/bbb/ccc does not
exist or /aaa/bbb/ccc is different from /rom/aaa/bbb/ccc.

It also works with '-c', but only effective for files touched
but not modified.
