b20b997c68 base-files: add /usr/share/libubox/jshn.sh to sysupgrade stage2
Discovered recent changes had broken sysupgrade for ar71xx mikrotik
rb-493g, traced the problem to missing /usr/share/libubox/jshn.sh after
switching to tmpfs.

6170c46b47 base-files: rename hostname with EUI of mac address
If a label MAC address is provided for device, system
will rename the hostname with OpenWrt_{eui mac address}.
This helps to distinguish between different devices.

Since it's no good idea to nest json_* functions, this code does
not use get_mac_label directly, but only get_mac_label_dt as
external resource.

a6fbdd3a78 base-files: don't store label MAC address in uci system config
If set, label MAC address is available from one of two sources,
device tree or board.json. So far, the function get_mac_label
was meant for retrieving the address, while an option in uci
system config was specified only for case 2 (board.json).

The uci config option has several drawbacks:
- it is only used for a fraction of devices (those not in DT)
- label MAC address is a device property, while config implies
  user interaction
- label_macaddr option will only be set if /etc/config/system
  does not exist (i.e. only for new installations)

Thus, this patch changes the behavior of get_mac_label:
Instead of writing the value in board.json to uci system config
and reading from this location afterwards, get_mac_label now
extracts data from board.json directly. The uci config option
won't be used anymore.
In addition, two utility functions for extraction only from DT
or from board.json are introduced.

Since this is only changing the access to the label MAC address, it
won't interfere with the addresses stored in the code base so far.

48b5d08a48 treewide: use a single ath10k MAC patching function with checksum
While all ath10k eeproms have a checksum field, so far two
functions for patching ath10k MAC address have been present (and
been used).

This merges code to provide a single function ath10k_patch_mac
in caldata.sh, having its name in accordance with ath9k functions.
By doing so, correct MAC patching for current and future ath10k
devices should be ensured.

This patch adds checksum adjustments for several targets on
ath79 and lantiq.

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.

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

With the function get_mac_label, the user can retrieve then

identifies his device.

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.

  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
root=/dev/ubiblock$X_$Y

9808bd2799 Revert "base-files: fwtool: Fix wrong checksum on combined-image with metadata"
This reverts commit 41770add03.

The fwtool_check_image() procedure is used by `sysupgrade --test` which must
not alter the image under test in any way.

Currently, when the LuCI ui or any other sysupgrade wrapper first invokes
sysupgrade --test to verify the compatibility of the image and then calculates
the sha256sum over it, the resulting checksum will differ from the original
image since the test invocation will implicitely strip the metadata trailer.

To properly fix the underlying issue, the combined image checksumming code
must be modified to skip the metadata trailer.

4097ab6a97 base-files: fix postinstall uci-defaults removal
Commit 7f694582 introduced a bug where default_postinst() often fails to
remove a uci-defaults script after application, leaving it to run again
after a reboot.
(Note: commit 7f694582 also introduced FS#1021, now fixed by 73c745f6)

The subtle problem arises from the shell logical chain:
[ -f "$i" ] && . "$i" && rm -f "$i"

Most uci-defaults scripts contain a terminal 'exit 0' statement which,
when sourced, results in the logic chain exiting before executing 'rm -f'.
This was observed while testing upgrades of 'luci-app-sqm'.

The solution is to wrap the shell sourcing in a subshell relative to the
command 'rm -f':
( [ -f "$i" ] && . "$i" ) && rm -f "$i"

Revert to using 'grep' to prefilter the list of entries from the control
file, which yields the full path of uci-defaults scripts. This allows
keeping the existence check, directory change and script sourcing inside
the subshell, with the script removal correctly outside.

This approach avoids adding a second subshell only around the "." (source)
command. The change also preserves the fix FS#1021, since the full path is
used to source the script, which is POSIX-portable irrespective of PATH
variable or reference to the CWD.

Run Tested on: LEDE 17.01.4 running ar71xx, while tracing installation of
package luci-app-sqm with its associated /etc/uci-defaults/luci-sqm file.

Add the opening bracket right after the function name, to do it the
same way for all functions in this file.

8174853c78 base-files: introduce sysupgrade signature chain verification
Verify ucert signature chains in sysupgrade images in case ucert is
installed and $CHECK_IMAGE_SIGNARURE = 1.
Also make sure ucert host binary is present and generate a self-signed
ucert in case $TOPDIR/key-build.ucert is missing.

1bad852ff5 base-files: network.sh: gracefully handle missing network.interface ubus ns
When attempting to use any of the functions in network.sh while netifd is
not started yet, the ubus interface dump query will fail with "Not found",
yielding an empty response.

Subsequently, jsonfilter is invoked with an empty string instead of a valid
JSON document, causing it to emit a second "unexpected end of data" error.

This caused the dnsmasq init script to log the following errors during
early boot on some systems:

    procd: /etc/rc.d/S19dnsmasq: Command failed: Not found.
    procd: /etc/rc.d/S19dnsmasq: Failed to parse json data: unexpected end of data.

Fix the issue by allowing the ubus query to fail with "Not found" but still
logging other failures, and by passing an empty JSON object to jsonfilter
if the interface status cache is empty.
