The Yafut tool now has limited capabilities for working on filesystem
images stored in regular files. This enables preparing Yaffs2 images
for devices with NOR flash using upstream Yaffs2 filesystem code instead
of the custom kernel2minor tool.
Since minimizing the size of the resulting filesystem image size is
important and upstream Yaffs2 code requires two allocator reserve blocks
to be available when writing a file to the filesystem, a trick is
employed while preparing an OpenWRT image: the blank filesystem image
that Yafut operates on initially contains two extra erase blocks that
are chopped off after the kernel file is written. This is safe to do
because Yaffs2 has a true log structure and therefore only ever writes
sequentially (and the size of the kernel file is known beforehand).
While the two extra erase blocks are necessary for writes, Yaffs2 code
seems to be perfectly capable of reading back files from a "truncated"
filesystem that does not contain these extra erase blocks.
In terms of image size, this new approach is only marginally worse than
the current kernel2minor-based one: specifically, upstream Yaffs2 code
needs to write three object headers (each of which takes up an entire
data chunk) when the kernel file is written to the filesystem:
- an object header for the kernel file when it is created,
- an object header for the root directory when the kernel file is
created,
- an updated object header for the kernel file when the latter is
fully written (so that its new size can be recorded).
kernel2minor only writes two of these headers, which is the absolute
minimum required for reading the file back. This means that the
Yafut-based approach causes firmware images to be at most one erase
block (64 kB) larger than those created using kernel2minor, but only in
the very unfortunate scenario where the size of the kernel file is
really close to a multiple of the erase block size.
The rest of the calculations performed when the empty filesystem image
is first prepared stems from the Yaffs2 layout used by MikroTik NOR
devices: each 65,536-byte erase block contains 63 chunks, each of which
consists of 1024 bytes of data followed by 16-byte Yaffs tags without
ECC data; each such group of 63 chunks is then followed by 16 bytes of
padding, which translates to "-C 1040 -B 64k -E" in the Yafut
invocation. Yaffs2 checkpoints and summaries are disabled (using
Yafut's -P and -S switches, respectively) as they are merely performance
optimizations that require extra storage space. The -L and -M switches
are used to force little-endian or big-endian byte order (respectively)
in the resulting filesystem image, no matter what byte order the build
host uses. The tr invocation is used to ensure that the filesystem
image is initialized with 0xFF bytes (which are an indicator of unused
space for Yaffs2 code).

The Yafut tool has so far been used to update the kernel on devices with
NAND flash via MTD character devices. Recent upstream updates extended
the tool with limited support for working with filesystem images stored
in regular files. This enables Yafut to be used for preparing a Yaffs
filesystem image for a device with NOR flash on a build host and
subsequently flashing it to the target device without using Yafut
itself.
Add Yafut to tools/ so that it can be compiled and run on the host
building OpenWRT.

Installation:
The installation must be done via TFTP by disassembling the router.
On other occasions Cudy has distributed intermediate firmware to make
installation easier, and so I recommend checking the Wiki for this
device if there is a more convenient solution than the one below.
To install using TFTP:
1. Upgrade to a beta firmware (signed by Cudy) that can be downloaded
from the wiki. This is required in order to use an unlocked u-boot.
2. Connect to UART.
3. While the router is turning on, press 1.
4. Connect to LAN and set your IP to 192.168.1.88/24. Configure a TFTP
server and an OpenWrt initramfs-kernel.bin firmware file as recovery.bin.
5. Press Enter three times. Verify the filename.
6. If you can reach LuCI or SSH now, just use the sysupgrade image with
the 'Keep settings' option turned off.
If you don't want to use the beta firmware nor the unlocked u-boot, you
can install the firmware writing the sysupgrade image on the firmware
partition of the SPI flash.

```
You can download the required U-Boot from this repository:
https://github.com/blocktrron/u-boot-msm/releases
Preparation
===========
Prepare a TFTP server serving two files:
- U-Boot NAND image as `msm460-uboot.bin`.
- OpenWrt factory image as `msm460-factory.bin`
- Command-file names `commands.tftp`
You can start a TFTP server in the current directory using dnsmasq:
```bash
sudo dnsmasq --no-daemon --listen-address=0.0.0.0 \
--port=0 --enable-tftp=enxd0 --tftp-root="$(pwd)" \
--user=root --group=root
```
Replace `enxd0` with the name of your network interface.
Procedure
=========
1. Assign yourself the IP-Address 192.168.1.66/24.
3. Connect the Router to the PC while keeping the reset button
pressed.
4. The LEDs will eventually begin to flash.
They will start to flash faster after around 15 seconds.
5. Release the reset button.
6. Start a new shell
7. Make sure you are currently in the directory where the tftp server
is located.
8. Run the following command:
```bash
tftp 192.168.1.1 -m binary -c put commands.tftp nflashd.cccc9999
```
You get the message "Transfer timed out."

The compiled library resulting from importing gnulib has been
linked to libelf in order to easily cover other link dependencies.
However, this is not appropriate for linking libelf to other programs
as it bloats the resulting libelf library, and may result in
multiple defintions of symbols based on whether or not
certain modules from gnulib are included while elfutils
already has it's own definition of a function.
This is not a problem while building elfutils, because gnulib has
it's own way of creating function aliases and special declarations
that allow the linker to ignore the original function definitions,
however, when libelf is used to link to something else,
this results in an error at link time.
The gnulib manual recommended linking the libraries directly,
but those who have written it may not have considered how this
can affect the ability to link that library in other builds,
they likely assume the build targets would not be a dependency.
Fix this by removing the linking between gnulib and libelf
and instead overriding Make variables in order to add linking
between gnulib and each of the binaries provided by elfutils,
using Make functions to avoid applying it to other subdirectories.
The function tdestroy() would still be missing on macOS,
but the existence of the gnulib tsearch object having been built
is an indicator of whether or not it is needed
because it is only built conditionally by gnulib,
so include linking that object only when it exists.
Block the unnecessary replacement of some functions by gnulib
so that future linking with libelf doesn't require
the associated gnulib "rpl" prefixed functions.
These replacements are very strict in order to correct
minor bugs that don't have a real impact in almost all cases
or new standards requirements that are not yet in effect or used.

The gnulib fts header is meant to not be overwritten
in any way by the host system's copy of fts.h
and was therefore given a unique name instead.
This is fine if the built libgnu library is directly linked
with the target library, but if we want to keep them isolated
we end up having the definitions being mangled anyway
when the next object to link against included the fts.h header.
On some macOS platforms, the use of __DARWIN_INODE64
is messing with the link name for fts functions, resulting in:
Undefined symbols for architecture x86_64:
"_rpl_fts_close$INODE64", referenced from:
...
Create a local fts header for gnulib
that completely blocks the macOS host fts header.
An alternative and more upstream friendly fix would be
to rename fts_.h to fts.h and add the macOS-only
include guard to that file within it's own include guard,
but that would be a massive patch, so do this for now.

ply is a light-weight dynamic tracer for Linux that leverages the kernel's
BPF VM in concert with kprobes/tracepoints to attach probes to arbitrary
points in the kernel.
Most tracers that generate BPF bytecode are based on the LLVM-based BCC
toolchain; ply on the other hand has no external dependencies outside libc,
making it suitable for use on constrained embedded systems.
Currently ply supports x86_64, aarch64, arm, riscv64, riscv32, powerpc,
mips(el), and mips64(el) architectures.
