[Solved] Asus RT-AC58U and OpenWrt 18.06 problem

I installed OpenWrt 18.06, OpenWrt good working before power off, but router not working after power off and power on after 5 minutes.

Not working after power on:

  • ssh not avaliable
  • http not avaliable
  • wifi working, but internet on connected devices not working
  • internet on connected devices via cable not working

My actions:

  • I installed OpenWrt 18.06 release (OpenWrt 18.06.0, r7188-b0b5c64c22)
  • I installed packages: nano dnscrypt-proxy
  • I connected via ssh and configured:
    configure /etc/config/dhcp (static IP some hosts and set dnscrypt-proxy parameters)
    configure /etc/config/dnscrypt-proxy
    configure /etc/config/network (change only mac adress)
    configure /etc/config/wireless
  • router good workiking before restart
  • power off router
  • waiting 5 minutes and power on rourer
  • router not working

I connected to router via com port and I see that some configuration files are not readable: dropbear firewall rpcd ucitrack uhttpd. The less command displays the contents of the files as '@@@@@@@@@@@', the cat/head commands displays the content of the file as empty.

I already tried several times:

  • I pressed the reset button 10 sec.
  • executed the firsboot command (soft reset) in Failsafe Mode.
  • re-installed the firmware image.

Can I have more ideas on how to restore the router.
PS: Sorry for my bad english.

The same thing happens here on R7800, I don't even install any packages, set setup pppoe and wireless and reboot, then I lost connection to my router though the browser. Some config files become unreadable. I am luckier than you since dropbear is readable so I can connect to the router with ssh.

Yes, you can not install packages, just turn off and on the power of the router, and some files will not be readable.
In unreadable files, I restored the original content and added the first line "# FIX" to make the content different from the original one. The router is still loading successfully, ssh and http are available. But if you do reset the router, then again there are broken files.
Example of a broken file /etc/config/ucitrack.
Is this the firmware bug?

I've duplicated this problem on using KVM and the x86-64 image from 17.01.5. At least in my case, it appears to be a problem with uninitialized itables on the root ext4 partition, similar to Read-only File System after a Fresh Installation of LEDE 17.01.5

You'll know you're running into this problem if you see ext4 errors like this on boot:

[    0.700769] EXT4-fs (sda2): mounted filesystem without journal. Opts: (null)
[    2.803919] EXT4-fs error (device sda2): ext4_has_uninit_itable:2883: comm mount_root: Inode table for bg 0 marked as needing zeroing
[    2.816869] EXT4-fs (sda2): Remounting filesystem read-only
[    2.821827] EXT4-fs (sda2): re-mounted. Opts: (null)
[    2.843009] EXT4-fs (sda1): mounted filesystem without journal. Opts: (null)

If you write any files, you'll see this flash by on a restart:

[  295.876810] EXT4-fs error (device sda2): ext4_remount:4797: Abort forced by user

Any files that get written to in this state will be trashed after a restart.

A workaround is to mount the ext4 partition on a Linux system, wait a bit, then umount it. Something like (you'll need to get the offset of the root partition using parted or something similar):

$ losetup -o 17301504 -f lede-17.01.5-x86-64-combined-ext4.img
$ mount /dev/loop0 /mnt/lede
$ sync
$ umount /dev/loop0
$ losetup -d /dev/loop0

This appears to be hit or miss on different images, possibly due to specifics on how the ext4 partitions are created (or possibly how long they were mounted during the image build process).

This is the root cause. The filesystems created by make_ext4fs do not set the EXT4_BG_INODE_ZEROED bit, even though, by the very nature of how they created (using sparse files and called'ed inode tables) they are actually zeroed.

Recent ext4 kernel changes pushed by Ted T'so have severely tightened checks on filesystems, and one of the checks is that this bit MUST be set on Block Group 0.

I think it's as simple as having make_ext4fs set this bit on all newly allocated block groups blindly. I'll test and send a patch to the openwrt-devel mailing list if this theory pans out.

Actually from your log messages it looks like you're using JFFS2/UBI so the ext4 problem is probably not relevant. Odd that it fails in the exact same way, though.

Yes, the router uses JFFS2/UBI.
There is a logread, maybe help diagnose the problem.

I got same problem before. I had to go back to Asus firmware then I flashed 18.06. No problem so far

Well, the ASUS Stock firmware calls the partition JFFS2... And while it's technically possible to put a jffs2 formatted partition in a UBI-Volume, it's a poor choice... first, jffs2 was designed around NOR-Flash and second there's already ubifs, so there's no need to include jffs2 support there. No idea what ASUS was thinking there :confused: .

Ok, can you tell how you did power off the router? Did you remove the power cord or pressed the power-off button while it was running? I'm asking because based on the "@@@@@@/0xff garbage in the files" symptoms, the RT-AC58U experienced a sudden-power loss while writing back the changes (the SPINAND is slooow). What you could do to prevent that is to perform a proper software reboot (either via the serial-console/ssh "reboot" or the Luci's "system reboot" option)... and wait until the device did it's initial LED test before disconnecting the power.

This is the Log OpenWrt 18.06, no log ASUS Stock firmware

I pressed the power-off button while it was running.

I know, I added support for the RT-AC58U in OpenWrt I can tell the difference between the ASUS firmware log and OpenWrt. This was about JFFS2/UBI and why OpenWrt does not use JFFS2.

ok, this might be the cause for the corruption. NAND flash is not as durable or easily programmable as NOR, so changes to files is not directly written in order to preserve the longevity of the flash cells. So this can be mitigated by doing issuing a software reboot of the OS, before turning it off.

If you don't care about longevity, you can of course (re-)mount the /overlay with the sync option: http://www.linux-mtd.infradead.org/doc/ubifs.html#L_sync_semantics

I executed the reboot command in ssh after installing the OpenWrt firmware.
Yes, this method works! No broken files.
Thank you very much!!!

PS: I recovered the router via serial cable after an unsuccessful attempt to flash from snapshot to release, so the router was on the table next to me. So it was convenient for me to press the power button. Now I will know that I do not have to press the power button after installing the firmware.

/sbin/poweroff would be another alternative, this doesn't necessarily work on all targets (it does work on ar71xx and ipq806x), but it's worth a try.

I reflashed it and reboot from the Luci interface, yeah, it works. thanks. (R7800)

very true. Most embedded platforms don't have a real poweroff feature like the big x86s. if poweroff is issued the devices will simply reboot instead. A we had this problem with My Book Live NAS (apm821xx) too and to solve it there I wrote a "softoff" script that utilizes sysupgrade to get in an idle state, where the device could be disconnected without any fear of corruption.


(The softoff.sh will work on all OpenWrt devices from 18.06+, but this version requires hdparm. so # opkg update ; opkg install hdparm )

I saw a JFFS2 init message in the boot log but missed that it wasn't being used by any partition. My bad, apologies for derailing the conversation.

Out of curiosity, would a manual sync(8) after editing files on a NAND flash partition avoid the file corruption, or are there too many levels of indirection/caching and you still need to use the softoff script?
