"ksmbd: cli req too short" all over dmesg #594

Closed raenye closed 9 months ago

raenye commented 11 months ago

Hello,

I started using ksmbd on a WD MyBookLive device running OpenWrt, and my logs are filled with this message (idle and transfer) File access seems to work fine. There is some periodicity in the timing, which changes over time (used to be three every 30 secconds, a few days later three every 40 secconds, in the logs below it's three plus one lagging. Clients are a few Win11 laptops and desktops.

Please advise.

Thanks, R.

Note that it's mostly len 112 not 116 but sometimes len 136 not 140. I haven't seen other numbers.

The mid counter resets very rarely, after a sock_read failed: -108:

namjaejeon commented 11 months ago

What is meaning ksmbd-server ? Does that mean ksmbd.mountd?

raenye commented 11 months ago

Versions of the relevant openwrt packages. But ksmbd.{mountd,control,addshare,adduser} -V all return ksmbd-tools version : 3.4.8.

namjaejeon commented 11 months ago

kmod-fs-ksmbd - 5.15.120-1

What ksmbd kernel module are you using ? Can you test it with the latest #master of ksmbd ?

https://github.com/cifsd-team/ksmbd

Thanks.

neheb commented 11 months ago

OpenWrt no longer uses the module but the upstream driver.

raenye commented 11 months ago

5.15.120. I could try with 5.15.123, but the kernel is compiled as part of the OpenWrt build process, and I'm not sure how to make it use a git tree.

root@fenix:~# strings /lib/modules/5.15.120/ksmbd.ko | grep 5.15
vermagic=5.15.120 mod_unload
raenye commented 11 months ago

the upstream driver.

Thanks. I was advised on the forum to open an issue here; where should I ask then?

neheb commented 11 months ago

This is the proper place.

raenye commented 11 months ago

So I'm not sure what is the difference between upstream and here, or between "module" and "driver" :(

neheb commented 11 months ago

Upstream I meant by kernel.org.

raenye commented 11 months ago

Anyway, I'll gladly build with debug options, test, and provide more information if you could tell me what is needed. Thanks.

namjaejeon commented 11 months ago

@raenye Can you give me wireshark dump (or tcpdump) after capturing packets on problem situation ?

raenye commented 11 months ago

@namjaejeon I narrowed it down to OneNote for Microsoft 365 running on one particular Win11 PC. The client has several open notebooks that reside on the server running ksmbd, tcpdump shows some client-server synchronization of cached copies over SMB. For instance, the log messages

Mon Jul 31 01:25:55 2023 kern.err kernel: [823130.727969] ksmbd: cli req too short, len 112 not 116. cmd:10 mid:186162

seem to relate to the following packets captured with tcpdump -A port 445:

Hoping this helps to reproduce an equivalent setup; alternatively, perhaps could you kindly write which tcpdump parameters would be useful for debugging.

Thanks!

Okay. I could not reproduce it using windows 10 client. I will try OneNote for Microsoft 365.

raenye commented 11 months ago

OneNote for Windows 10 is a different program, it's cloud only; only OneNote desktop (was 2016, then 365) can do local notebooks. Please let me know if further information is needed. Thanks.

Update: I upgraded from kernel 5.15.133 to 6.1.55 and the problem disappeared. No change in clients. Should I closed as resolved?

namjaejeon commented 9 months ago

@raenye Yes, You can close this ISSUE. Thanks!

I just like to leave a comment here telling that I experience currently the same issue with OneNote365 running on a Win11 PC. The notebooks are stored on the ksmbd share. The log is spammed with the same error messages as described in the first post by @raenye.

Beside the anoying error messages there is a really nasty problem. The OneNote notebooks are not syncing properly anymore. As soon as you add a new chapter to a notebook it starts complaining. So basically OneNote is not useable anymore with ksmbd running on kernel 5.15 and as this is the current stable in OpenWrt it is a really bad situation. I can imagine that it takes quite some time until the 6.1.55 will become the next stable release.

I found out that creating a new tab in OneNote typically creates a new file where the notebook is stored. The file on the ksmbd share is only half the size compared to the size when the notebook is on a different share. On the different share no complains about syncing.

It would really be beneficial if anyone knows how to bypass this issue.

@Luckyparty I am backported ksmbd patches to new linux-5.15.145. It is not released yet. I think that openWRT can pull linux-5.15.145 after it is released.

If you want to check your issue with ksmbd backport patches right now, you can use the following kernel.

git clone https://github.com/namjaejeon/stable-linux-5.15-ksmbd

Thanks.
