Oliver can you please record the test logs with '-o results.json' and
include that file in the download directory?

I attached one results.json FYI.

it need some code change to upload it to download directory, we will consider
to implement it in the future. thanks

Hi!
> I attached one results.json FYI.

Looks like the test is getting unexpected EINVAL when reading from files
from /proc/sys/net/ipv4/neigh/default/ and
/proc/sys/net/ipv6/neigh/default/ directories.

Please do so, without the logs it's much harder to debug the problems.

not sure if you need further information?

got it. we've implement the feature. will directly upload results.json to
download directory for future ltp reports. thanks!

I can see the errors and I can reproduce on my side. I'll take a look.
thx.

BTW: I saw this path in the logs
/proc/sys/net/ipv5/neigh/default/anycast_delay

not sure if "ipv5" is part of the suit, but worth mentioning from my
side.

The proc01 test walks over proc files and attempts to read one after
another. It does not invent paths that are not on the system already.

This is all fixed in linux-next. Feel free to scream at me if you see
more sysctl errors.

oops. I re-downloaded the json results and it was not there any more.
I probably inadvertently change the file while looking at it
Sorry for the noise.

Thx for the report
