Patch bumping kernel 4.14.91 to 4.14.93 breaks normal work! (Breed bootloader)

#1

Hi there!
My device is Xiaomi Mi Wifi Router 3G, and I regularly build pre-configured OpenWRT firmware with some additional software (kernel modules, packages) built-in, for my own use. And all updates before 14.01.2019 were OK. But from 14.01.2019, after this patch: https://github.com/openwrt/openwrt/commit/8c6f00ef4f17999c5110166764773e40b9a934de
kernel/Linux not working as expected. While some parts of kernel thinks that kernel version is 4.14.93, some other kernel parts (and Linux at all) thinks that kernel version 4.14.91 (dmesg log and uname, for example). But all the kernel modules are located in /lib/modules/4.14.93 but none is loaded nor at boot time, nor later with modprobe/insmod. lsmod gives blank output

I tried to reconfigure from scratch (deleting everything, then git clone ... make menuconfig ... and so on) but it didn't help. Moreover, I downloaded automatically built snapshot from here: https://downloads.openwrt.org/snapshots/targets/ramips/mt7621/openwrt-ramips-mt7621-mir3g-squashfs-sysupgrade.bin
and result is the same: none of modules are loaded, even pre-installed in snapshot (for example, pppoe - because my internet connection type is PPPoE).
Then I tried to make necessary dir: /lib/modules/4.14.91 (making a symlink to /lib/modules/4.14.93 or simply making the dir and copying everything from 4.14.93 to 4.14.91). The result is - device immediately hangs and then, after reset, cannot boot (hangs on boot) anymore.
Of couse, many times I restored to my previous OpenWRT firmware (r9019, updated and built on 13.01.2019) with restoring of all my settings, and it worked as if nothing had happened. Many times I erased all my settings (with firstboot) and then upgrading to new firmware with "half-working" kernel... But nothing helps.

Please, fix this! I cannot fix because I don't know where to look and even from where to start investigating. Searching for "4.14.91" or "14.91" in all OpenWRT files did not give any valuable result.
Or please tell me how to fix, where to look.

Thanks!

Try latest master 4.14.94

I had the same issue. I just remove "bin" directory so all modules from kernel version 91 was deleted and only 93 was created.

I investigated deeper and it turned out that actually the problem is in sysupgrade, not in kernel. I made full *.bin file for Breed bootloader - and now all OK: kernel version 4.14.94 showing everywhere and loads all the modules as expected. For now I don't know - maybe it was needed to sysupgrade the same *sysupgrade.bin twice?
Thanks for answers, it gave me a hunch about the root of the problem: sysupgrade.

can you explain how you made your "full *.bin" for breed? Would be very interested in using breed for flashing OpenWRT! :slight_smile:

@Ykidia , @thorsten97 , please share your ideas on how to create valid *.bin files for BREED.
Do you know the .bin file of the stock firmware can be deconstructed to generate *.bin files for BREED?

Thanks a million!

Got from 4pda.ru/forum, Windows cmd/bat-file with following contents:

@echo off

if "%~1" neq "" (echo %~1) else (goto help)
del /q /f openwrt_for_breed.bin >nul
del /q /f ~tempfile >nul
del /q /f ~kernel* >nul
set size=0
for %%I in (%1) do set/A size=4194304-%%~zI
fsutil file createnew ~tempfile %size%
copy /b %1+~tempfile ~kernel
del /q /f ~tempfile >nul
copy /b ~kernel+~kernel ~kernel1
copy /b ~kernel1+%2 openwrt_for_breed.bin
del /q /f ~kernel* >nul
exit
:help
echo.
echo.This will make OpenWrt binary file for using with Breed for Mi Router 3G.
echo.
echo Usage:
echo create_openwrt_for_breed.cmd {kernel1 file} {rootfs0 file}
echo.
echo Example: %0
echo create_openwrt_for_breed.cmd openwrt-18.06.0-ramips-mt7621-mir3g-squashfs-kernel1.bin openwrt-18.06.0-ramips-mt7621-mir3g-squashfs-rootfs0.bin
echo.

pause

I.e. we adding bytes to kernel1 up to 4MB then: kernel1(4MB)+rootfs0 = full breed image. Then flashing this via Breed to 2nd part.

Thanks for the windows script.
Ok, what you are basically saying is: Given you selected "firmware section 2", BREED takes any file and flashes it to either (if you are on stock firmware)
mtd9: 00400000 00020000 "kernel1" (4 MiB)
mtd10: 02000000 00020000 "rootfs0" (32 MiB)

or to (if you are on OpenWRT)

mtd8: 00400000 00020000 "kernel" (4 MiB)
mtd9: 07580000 00020000 “ubi” (120 MiB)

right? So BREED does not uncompress any .bin file, right?
If you intend to flash padavan, for instance, then you want BREED to flash a .trx file, which, AFAIK, is a compressed image ... This BREED thing is just a big ball of unknown mud. Nobody knows, except Hackpascal, what it is doing and what not.

Ok, do you know if these .bin files from Xiaomi containing stock firmware have the same layout and no compression als the .bin files that are generated by this script?

Thanks and best wishes!

Should this work on linux?

truncate -s 4M kernel1.bin   ### to make the kernel1 4Megs in size
cat kernel1 rootfs0 > full.bin ### combine both into one

would be fantastic as I hate this extra stepp of flashing stock first ...

@thorsten97
You can try this three lines here .. However, I don't provide any warranty for them. Do it on your own risk!!! If your router doesn't start anymore, be sure to have a fallback solution to bring it back to life!
I'm not responsible for any damage whatsoever!

But I do think, this three-liner works as intended:

tr '\0' '\377' < /dev/zero | dd of=mir3g_kernel1_rootfs0_breed.bin ibs=1k count=36k
dd if=kernel1.bin of=mir3g_kernel1_rootfs0_breed.bin seek=0 obs=1k conv=notrunc
dd if=rootfs0.bin of=mir3g_kernel1_rootfs0_breed.bin seek=4k obs=1k conv=notrunc

You need two files:

  1. a kernel1.bin which denotes a kernel partition saved to a file that should be flashed to firmware section 2. Please do not touch firmware section 1, because that's your recovery partition. Please notice that the script @Ykidia has posted here, generates .bin files suitable for flashing section 1 and 2. Have a look at line 12 of that script to see what I mean ... Frankly speaking I would advise against its use ...

  2. rootfs0.bin which denotes a root file system partion, which should go to mtd partition "rootfs0".

So what my script basically does is write a file that is 36MiB long, that is the size of the kernel0 plus the rootfs0 partition. Then it writes the contents of file "kernel1.bin" to the aforementioned file at offset 0. Then it takes the "rootfs0.bin" and writes its contents to the generated file at position 4MiB. The first, generated file is not truncated during these operations. So it maintains its size and only contents of the other files are filled in.

Please give it a shot and report back if it works. Thanks for your testing!

Cheers, DFahren

Hmmm, that's bad news. No, I didn't try yet. What's the output on the serial console?

That really, really puzzles me ... Did you set "autoboot.command boot flash 0x600000" in BREED?
Other idea would be, use the windows script and see if that works.

under Windows this works:

for /f %%i in ("openwrt-18.06-4.14.93-ramips-mt7621-mir3g-squashfs-kernel1.bin") do ( set /a size = 4194304 - %%~zi >nul )
fsutil file createnew dummy.bin %size% >nul
copy /y /b openwrt-18.06-4.14.93-ramips-mt7621-mir3g-squashfs-kernel1.bin + /b dummy.bin + /b openwrt-18.06-4.14.93-ramips-mt7621-mir3g-squashfs-rootfs0.bin breed-firmware.bin >nul
del dummy.bin

if I interpret it correctly, it is exactly what your linux command should do, right?

Really, that's interesting. Taking your script and trying to run it from Windows 7 Enterprise shows the error "missing operand" in line 1. But, yes, your script should in fact does the same as mine, but no idea why mine does not work. Have to check the resulting output from both.

The following script seems to create the correct bin file for Breed:

#!/bin/bash
if [ $# -ne 2 ]; then
    echo Usage: $0 "kernel1.bin" "rootfs0.bin"
    exit 1
fi
kernel1="$1"
rootfs0="$2"
[ -f "$kernel1" ] || { echo "kernel1 file doesn't exist, aborting: $kernel1"; exit 1; }
[ -f "$rootfs0" ] || { echo "rootfs0 file doesn't exist, aborting: $rootfs0"; exit 1; }
[[ ${kernel1##*/} =~ .*kernel1\.bin ]] || echo "first parameter must be kernel1.bin, aborting"
[[ ${rootfs0##*/} =~ .*rootfs0\.bin ]] || echo "second parameter must be rootfs0.bin, aborting"
tmpfile=$(mktemp tmp.XXXXXX)
truncate -s 8M "$tmpfile"
dd if="$kernel1" of="$tmpfile" conv=nocreat,notrunc status=none oflag=seek_bytes seek=0
dd if="$kernel1" of="$tmpfile" conv=nocreat,notrunc status=none oflag=seek_bytes seek=4M
