tools/missing-macros: prefer macros provided by gnulib source
These 7 macro files are provided by gnulib,
so we can now replace these statically stored copies
with the latest copy from GNU sources.

tools: add gnulib source
By having a local copy of gnulib, we can:
import the latest macro fixes into any package,
get rid of some statically stored macros that were otherwise missing,
bootstrap GNU tools with the latest relevant source
without having to wait for a release or rely on git submodules,
and possibly more...

The patch assists in bootstrapping by ignoring
the building of po files using gettext,
and also to allow a user-defined path to a program
to include parameters.

prereq-build: add check for true and false
Some uses cases, like with autotools, need a path for 'true'
if we use them to force something to skip.

This will work by default on Linux hosts,
and require MacOS hosts to get coreutils,
which is currently installed in the CI
for 'macos-latest' host.

In the future, prereq stage can be reworked
to search for the actual binary
instead of relying on env.

lantiq: xrx200: mark subtarget as source-only
The current problems blocking the switch to the kernel 5.15 are
related to the GSWIP driver. This driver is only used by the

3d66f55161 kernel: improve handling of CONFIG_IO_URING
Kernel setting CONFIG_IO_URING supports high-performance I/O for file
access and servers, generally for more performant platforms, and adds
~45 KB to kernel sizes. The need for this on less "beefy" devices is
questionable, as is the size cost considering many platforms have kernel
size limits which require tricky repartitioning if outgrown. The size
cost is also large relative to the ~180 KB bump expected between major
OpenWRT kernel releases.

No OpenWrt packages have hard dependencies on this; samba4 and mariadb
can take advantage if available (+KERNEL_IO_URING:liburing) but
otherwise build and work fine.

Since CONFIG_IO_URING is already managed via the KERNEL_IO_URING setting
in Config-kernel.in (default Y), remove it from those target configs
which unconditionally enable it, and update the defaults to enable it
conditionally only on more powerful 64-bit x86 and arm devices. It may
still be manually enabled as needed for high-performance custom builds.

4a043dc9d4 ramips: add factory image for TP-Link EC330-G5u v1
This commit adds factory.bin image for TP-Link EC330-G5u v1. This allows
to install OpenWrt without connecting a serial cable (UART).

Installation using factory image
--------------------------------

Tested with "3.16.0 0.9.1 v6037.0 Build 191016 Rel.30619nb" TP-Link
firmware.

1.  Login to the router web interface (http://192.168.0.1/ by default) and
    save running config to "conf.bin" file
2.  Open configuration file in any TP-Link config editor (e.g.
    https://jahed.github.io/tp-link-config-editor/)
3.  Find "DeviceInfo" section and insert a new string "<Description
    val="Modem Router`telnetd -p 1023 -l login`" />" according to the
    following example:
       <DeviceInfo>
          ...
          <Description val="Modem Router`telnetd -p 1023 -l login`" />
          ...
       </DeviceInfo>
4.  Save configuration file and upload changed configuration using stock
    firmware interface
5.  Login using telnet to IP:192.168.0.1 (Username:admin, password:1234)
6.  Run "cat /proc/mtd | grep mtd7"
       a. If the result is 'mtd7: 03000000 00020000 "rootfs" 03400000',
          then install stock firmware using web interface to toggle booted
          firmware image from "os1" to "os0"
       b. If the result is 'mtd7: 03000000 00020000 "rootfs" 00400000',
          then all is ok, go to the next step
7.  Set up a tftp server with OpenWrt factory.bin image (IP:192.168.0.100
    in this example)
8.  Login using telnet to 192.168.0.1
9.  Download OpenWrt factory.bin image from the tftp server:
       cd /tmp
       tftp -g -r factory.bin 192.168.0.100
10. Write OpenWrt factory.bin image:
       dd if=/tmp/factory.bin of=/dev/mtdblock1
11. Power cycle the router

28df7f7ff2 ramips: mt7621: add support for ZyXEL WSM20
The ZyXEL WSM20 aka Multy M1 is a cheap mesh router system by ZyXEL
based on the MT7621 CPU.

Specifications
==============

SoC: MediaTek MT7621AT (880MHz)
RAM: 256MiB
Flash: 128MiB NAND
Wireless: 802.11ax (2x2 MT7915E DBDC)
Ethernet: 4x 10/100/1000 (MT7530)
Button: 1x WPS, 1x Reset, 1x LED On/Off
LED: 7 LEDs (3x white, 2x red, 2x green)

MAC address assignment
======================

The MAC address assignment follows stock: The label MAC address is the LAN
MAC address, the WAN address is read from flash.

The WiFi MAC addresses are set in userspace to label MAC + 1 and label MAC
+ 2.

Installation (web interface)
============================

The device is cloud-managed, but there is a hidden local firmware upgrade
page in the OEM web interface. The device has to be registered in the
cloud in order to be able to access this page.

The system has a dual firmware design, there is no way to tell which
firmware is currently booted. Therefore, an -initramfs version is flashed
first.

1. Log into the OEM web GUI
2. Access the hidden upgrade page by navigating to
   https://192.168.212.1/gui/#/main/debug/firmwareupgrade
3. Upload the -initramfs-kernel.bin file and flash it
4. Wait for OpenWrt to boot and log in via SSH
5. Transfer the sysupgrade file via SCP
6. Run sysupgrade to install the image
7. Reboot and enjoy

NB: If the initramfs version was installed in RAS2, the sysupgrade script
sets the boot number to the first partition. A backup has to be performed
manually in case the OEM firwmare should be kept.

Installation (UART method)
==========================

The UART method is more difficult, as the boot loader does not have a
timeout set. A semi-working stock firmware is required to configure it:

1. Attach UART
2. Boot the stock firmware until the message about failsafe mode appears
3. Enter failsafe mode by pressing "f" and "Enter"
4. Type "mount_root"
5. Run "fw_setenv bootmenu_delay 3"
6. Reboot, U-Boot now presents a menu
7. The -initramfs-kernel.bin image can be flashed using the menu
8. Run the regular sysupgrade for a permanent installation

Changing the partition to boot is a bit cumbersome in U-Boot, as there is
no menu to select it. It can only be checked using mstc_bootnum. To change
it, issue the following commands in U-Boot:

   nand read 1800000 53c0000 800
   mw.b 1800004 1 1
   nand erase 53c0000 800
   nand write 1800000 53c0000 800

This selects FW1. Replace "mw.b 1800004 1 1" by "mw.b 1800004 2 1" to
change to the second slot.

Back to stock
=============

It is possible to flash back to stock, but a OEM firmware upgrade is
required. ZyXEL does not provide the link on its website, but the link
can be acquired from the OEM web GUI by analyzing the transferred JSON
objects.

It is then a matter of writing the firmware to Kernel2 and setting the
boot partition to FW2:

   mtd write zyxel.bin Kernel2
   echo -ne "\x02" | dd of=/dev/mtdblock7 count=1 bs=1 seek=4 conv=notrunc

f01fff63fb umbim: add "_proto_mbim_get_field" helper
Add a new helper to extract IP configuration from umbim output. This is
required to extract fields which can possibly have multiple values,
namely IP addresses and DNS servers, and get rid of primitive parser
using 'eval' builtin without support for this.

9ddbcd73d8 umbim: pass ipXtable to child interfaces
Inspired by commti e51aa699f7, allow setting specific routing tables
via ip4table and ip6table options, by passing them on child interfaces
created by MBIM protocol handler.

ca8df8a992 umbim: use static config by default, fallback to DHCP
Finally, inspired by ModemManager's logic, make static configuration
obtained through MBIM control channel, preferred.
If IP configuration is not available this way, fallback to DHCP(v6) if
enabled, else do not create a sub-interface for unavailable IP type.

464d81fe4a umbim: separate DHCPv6 configuration from DHCP(v4)
Now, that sub-interface setup is split by IP type, and separate checks
are performed for DHCP selection, it is possible to control DHCP on v4
an v6 sub-interfaces instantly. Add "dhcpv6" variable, akin to QMI
option, to control behaviour of DHCPv6 separately from IPv4 option,
which is required for some mobile operators.

03692dee73 umbim: restructure IPv4/IPv6 handling
Check whether interface is configured per IP type, not per DHCP. This is
preparation to allow fallback to DHCP if static IP configuration is not
available, which is the default option for MBIM modems

9bb4b9a968 umbim: use IP configuration provided by MBIM by default
Previously, DHCP was used. According to MBIM Specification v1.0 errata 1 [1],
section 10.5.20, MBIM_CID_IP_CONFIGURATION,
if MBIM information element containing IP configuration is available,
host shall use it, and fall back to in-band mechanisms to acquire it therwise -
therefore make static configuration the default.

356a6f0eee umbim: detect actual connection IP type
Current implementation needlessly creates both IPv4 and IPv6
sub-interfaces for single-stack IP types. Limit this only to selected IP
type. While at that, ensure that IP type is also passed to umbim during
"connect" phase. In addition, detect the actual established connection
type returned by umbim and set up subinterfaces according to that,
not to requested configuration. While at that, allow empty IP type explicitly,
interpreted as "any" according to MBIM specification.

da84eddedb umbim: fail connect step immediately
Subsequent calls to 'umbim connect' do not have any effect if a failure
occured, and in such case an infinite loop without timeout is created,
leading to possibility of interface stuck at connecting forever.
Drop this loop, and issue MBIM disconnect properly, so netifd can
restart from scratch.
This issue can be observed with Sierra EM7455 at changing APN, which
causes network re-registration by default, and a MBIM transaction
timeout, which is resolved on next interface bringup by netifd.
