Hi all,

I'm currently in the process of updating the kernel version within OpenWrt.
(4.14.68 to 4.14.69)

Testing shows some issues on devices using specifically UBIFS.
Altering a perfect valid writable file shows weird errors:


[ Node 2 | node-2 ] ls -l /root/custom/scripts/banner.sh
-rwxr-xr-x    1 root     root           283 Sep 11 09:52
/root/custom/scripts/banner.sh

[ Node 2 | node-2 ] cat /root/custom/scripts/banner.sh
#!/bin/sh

if [ ! -f /root/.banner_ok ]
then
     RELEASE=$(cat /root/build_date)
     VERSION=$(cat /root/version)

     echo "Generating banner: $VERSION $RELEASE"
     sed s/VERSION/$VERSION/g /root/custom/banner > /etc/banner
     sed -i s/RELEASE/$RELEASE/g /etc/banner

     touch /root/.banner_ok
fi

[ Node 2 | node-2 ] echo "test" > /root/custom/scripts/banner.sh
-ash: can't create /root/custom/scripts/banner.sh: nonexistent directory



I'm also noticing other apps fail because /etc doesn't exists yet after
UBIFS boot loading.
these 2 issues were not seen on 4.14.68.

The bootlog doesn't show any error:

I'm only seeing these issues on UBIFS enabled volumes.
Reverting ("ubifs: xattr: Don't operate on deleted inodes") fixes these
weird issues.
Please see my answer to the other thread.
Always keep the patch author on CC and don't start multiple threads for the
same issue on two mailing lists.
Yes, I didn't answer for three days, I had no internet connection...

Richard,

I indeed posted here too as we passed the 3 days marker, and I noticed 4.14.70 RC2 got staged. Also, a lot of developers tend to ignore questions unless the initial question got posted to the official mailinglist.

Let's continue on the OpenWrt list as you propose, were the initial question was raised.

Apologies for the (double) noise.


Thank you,

Koen
