ccac75a37f base-files: fix uid/gid auto-enumeration to avoid 16-bit limit
uid/gid range should be limited to 16bit unsigned integer range to
avoid "wraparound" issues with permissions where jffs2
is employed for storage and chown 65536 (first auto-created user)
becomes equivalent to chown 0

Fixes: #13927

6b7c4739c4 base-files: execute package's "postinst" after executing uci-defaults
Allow "postinst" scripts to perform extra actions after applying all
kind of fixups implemented using uci-defaults.

This is needed e.g. by uhttpd-mod-ubus which after installation in a
running systems needs to:
1. Update uhttpd config using its uci-defaults script
2. Reload uhttpd

While this approach makes sense there is a risk it'll blow up some
corner case postinst usages. There is only 1 way to find out.

base-files: fix wrong ucidef_set_network_device_mac network-device entry
The ucidef_set_network_device_* functions in uci-defaults.sh disagree
on whether to use "network-device" or "network_device" in board.json.
With the additional caveat that jshn will translate hyphens (-) into
underscores (_). This casues problems in netifd which expected
"network_device" causing boards which depend on assigning MACs in
board.json via uci-defaults.sh (or jshn in general) to fail.

This commit addresses the issue by using network_device in
uci-defaults.sh.

The bug was uncovered in the forums here:
https://forum.openwrt.org/t/support-for-rtl838x-based-managed-switches/57875/2596

This was exposed by commit 4ebba8a05d ("realtek: add support for HPE
1920-8g-poe+") where the board_config_load call from 03_gpio introduced
the key normalization by jshn.

base-files: sysupgrade: Add 2 sec sleep into process KILL loop
Add 2 seconds sleep after each forcibly killed/tried-to-kill process
in the final process termination loop in sysupgrade stage2.

This is needed especially for qualcommax/ipq807x, where ath11k
wireless driver may have a long 10-20 seconds delay after termination
before actually getting killed. This often breaks sysupgrade.

The current KILL loop in kill_remaining does all 10 kill attempts
consecutively without any delay, as evidenced here in a failing sysupgrade.
It does not allow any time for the process to finalize its internal
termination.

The change in this commit adds a 2 seconds delay after each kill attempt
in order to allow some processes to more gracefully handle their
internal termination.

The result is like this:

Sun Sep  3 11:15:10 EEST 2023 upgrade: Sending TERM to remaining processes ...

The delay introduced here only kicks in if there is some process that
does not get terminated by the first TERM call. Then there is at least
one 2 sec wait after the first KILL loop round.

3da70c6469 base-files: Do not break on non-eth ports
When using OpenWRT with DSA and 'lan' ports, we could get an empty
`next_eth`. This is of course not desirable, as this causes `sh: out of
range` errors when trying to determine which one would be greater.

It turns out, that we don't even need this check at all because, when
looking for all existin eth*s on a system, and take the highest index
and then iterate a set of devices and rename to eth${highest_index+n},
it is guaranteed that there will be no conflict.

665c2154ef ramips: add basic support for tp-link er605-v2
This is a MT7621-based device with 128MB NAND flash, 256MB RAM, and a USB port.
The board has headers to attach console. In order for them to work two solder
bridges near those pads need to be made.

The defice has the following partition table:

```
0x000000000000-0x000000080000 : "u-boot"
0x000000080000-0x000000100000 : "u-boot-env"
0x000000100000-0x000000140000 : "factory"
0x000000140000-0x000007e00000 : "firmware"
0x000007e00000-0x000008000000 : "panic-ops"
```

`firmware` partition contains UBI volumes. Unfortunately I accidentally wiped
partition and I no longer have access to it.

`firmware` partition contains 'secondary' U-Boot which is run by 'first' u-boot.
It also contains various configuration partitions that include device info and
MAC address. There also seems to be 'primary' and 'backup' set of 'main' volumes.

U-boot has `mtkupgrade` command that just overrides data on firmware partitions.
Firmware file provided by TP-Link cannot be used with that command.

U-boot also has 'recovery' http server. Unfortunately I was not able to make it
work with manufacturer's firmware.

Manufacturer's firmware essentially contains multiple UBI volumes along with
'partition table'. Unfortunately I no longer can properly run manufacturer's
firmware so I cannot at the moment try to a support for building 'factory' images.

This patch adds support for initramfs image as well as sysupgrade image.

This seems to be pretty standard MT7621 board otherwise.

Things that work:
* network
* leds
* usb
* factory MAC detection

the same method used for the NanoPi R2S and R4S in case the EEPROM
chip is not present by generating the board MAC from the SD card CID.

9710712120 base-files: accept gzipped nand sysupgrade images
When firmware images only contained compressed kernels and squashfs roots,
uncompressed tar files were a good option. We are now using UBIFS images,
both raw and tarred, as well as ubinized (full UBI partition) images, all
of which benefit greatly from compression.

For example, a raw ubinized backup taken from a running Askey RT4230W REV6
(such full backups can be restored via the LUCI's sysupgrade UI) is over
400 MB, but compresses to less than 10 MB.

accepted by the nand sysupgrade mechanism, be them raw or tarred.

20581ee8b5 ath79: add support for TP-Link Deco S4
Add support for TP-Link Deco S4 wifi router

The label refers to the device as S4R and the TP-Link firmware
site calls it the Deco S4 v2. (There does not appear to be a v1)

Hardware (and FCC id) are identical to the Deco M4R v2 but the
flash layout is ordered differently and the OEM firmware encrypts
some config parameters (including the label mac address) in flash

In order to set the encrypted mac address, the wlan's caldata
node is removed from the DTS so the mac can be decrypted with
the help of the uencrypt tool and patched into the wlan fw
via hotplug

Specifications:
SoC: QCA9563-AL3A
RAM: Zentel A3R1GE40JBF
Wireless 2.4GHz: QCA9563-AL3A (main SoC)
Wireless 5GHz: QCA9886
Ethernet Switch: QCA8337N-AL3C
Flash: 16 MB SPI NOR

UART serial access (115200N1) on board via solder pads:
RX = TP1 pad
TX = TP2 pad
GND = C201 (pad nearest board edge)

The device's bootloader and web gui will only accept images that
were signed using TP-Link's RSA key, however a memory safety bug
in the bootloader can be leveraged to install openwrt without
accessing the serial console. See developer forum S4 support page

b688bf83f9 base-files: rename ethernet devs on known boards
Some platforms lack an established way to name netdevs; for example,
on x86, PCIe-based ethernet interfaces will be named starting from
eth0 in the order they are probed. This is a problem for many devices
supported explicitly by OpenWrt which have hard-wired, standalone or
on-CPU NICs not supported by DSA (which is usually used to rename the
ports based on their ostensible function).

To fix this, add a mapping between ethernet device name and sysfs
device path to board.json; this allows us to configure ethernet device
names we know about for a given board so that they correspond to
external labeling.

c9725d4fb6 failsafe: run on all consoles listed in /proc/cmdline
On x86, when both CONFIG_GRUB_CONSOLE and CONFIG_GRUB_SERIAL are set (as
they are by default), the kernel command line will have two console=
entries, such as

    console=tty0 console=ttyS0,115200n8

Failsafe was only running a shell on the first defined console, the VGA
console. This is a problem for devices like apu2, where there is only a
serial console and it appears on ttyS0.

Moreover, the console prompt to enter failsafe during boot was delivered
to, and its input read from, the last console= on the kernel command
line. So while the failsafe shell was on the first defined console, only
the last defined console could be used to enter failsafe during boot.

In contrast, the x86 bootloader (GRUB) operates on both the serial
console and the VGA console by virtue of "terminal_{input,output}
console serial". GRUB also provided an alternate means to enter failsafe
from either console. The presence of two console= kernel command line
parameters causes kernel messages to be delivered to both. Under normal
operation (not failsafe), procd runs login in accordance with inittab,
which on x86 specifies ttyS0, hvc0, and tty1, allowing login through any
of serial, hypervisor, or VGA console. Thus, serial access was
consistently available on x86 devices with serial consoles under normal
operation, except for shell access in failsafe mode (without editing the
kernel command line).

By presenting the failsafe prompt, reading failsafe prompt input, and
running failsafe shells on all consoles listed in /proc/cmdline,
failsafe mode will work correctly on devices with a serial console (like
apu2), and the same image without any need for reconfiguration can be
shared by devices with the more traditional (for x86) VGA console. This
improvement should benefit any system with multiple console= arguments,
including x86 and bcm27xx (Raspberry Pi).

34437af888 base-files: allow ignoring minor compat-version check
Downstream projects might re-generate device-specific configuration
based on OpenWrt's defaults on each upgrade, thus being unaffected by

Add a new sysupgrade parameter, which allows sysupgrades between minor

versions.

7d02fc0951 base-files: fix sysupgrade for kernel-out-of-UBI
Commit ecbcc0b595 bricks devices on which the raw kernel and UBI mtd
partitions overlap.

This is the case of the ZyXEL NR7101 for example. Its OEM bootloader has
no UBI support. OpenWrt splits the stock kernel mtd partition into a raw
kernel part used by the bootloader and a UBI part used to store rootfs
and rootfs_data. Running mtd erase on the complete partition during
sysupgrade erases the UBI part and results in a soft brick.

Arguably the best solution would be to fix the partition layouts so that
kernel and UBI partitions do not overlap, also including a stock_kernel
partition to help reverting to stock firmware. This would have the added
benefit of protecting UBI from kernel images that are excessively large.

17b05045bd ipq40xx: Support Chromium OS image-type creation
See firmware-utils.git commits [1], which implemented the cros-vbutil
verified-boot payload-packing tool, and extended ptgen for the CrOS
kernel partition type. With these, it's now possible to package kernel +
rootfs to make disk images that can boot a Chrome OS-based system (e.g.,
Chromebooks, or even a few AP models).

Regarding PARTUUID= changes: Chromium bootloaders work well with a
partition number offset (i.e., relative to the kernel partition), so
we'll be using a slightly different root UUID line.

NB: I've made this support specific to ip40xx for now, because I only
plan to support an IPQ4019-based AP that uses a Chromium-based
bootloader, but this image format can be used for essentially any
Chromebook, as well as the Google OnHub, a prior Chromium-based AP using
an IPQ8064 chipset.
