issue on ksmbd 3.4.4 and thunar mount on linuxlite 4.8 #554

Closed pesa1234 closed 2 years ago

pesa1234 commented 2 years ago

Hi, sorry to bother you again. LinuxLite 4.8 have Kernel: 4.15.0-74 Based on ubuntu: 18.04.3 With ksmbd 3.4.4 and thunar when i try to mount my ksmbd share it ask everytime for username and password, also for guest account... Attached tcpdump. dump.pcapng.zip

With ksmbd 3.4.3 all was ok, also dolphin on Fedora with this mod https://github.com/namjaejeon/ksmbd/commit/f1e91cd035b5227eec762b0a575b1aefa1156f6b

namjaejeon commented 2 years ago

What is client ? cifs or Nautilus ? and I think that ksmbd 3.4.4 doesn't support 4.15 kernel. ksmbd supports from 5.4 kernel.

namjaejeon commented 2 years ago

have you updated ksmbd-tools 3.4.4 also ?

namjaejeon commented 2 years ago

With ksmbd 3.4.3 all was ok, also dolphin on Fedora with this mod namjaejeon@f1e91cd

When I checked patches between 3.4.3 and 3.4.4 version, there is no related patches. Can you confirm that it work with 3.4.3 version again after downgrade ksmbd version ?

pesa1234 commented 2 years ago

Hi, yes updated also ksmbd-tools I use thunar on that distro but nautilus is same. I confirm that ksmbd 3.4.3 on openwrt router OK ksmbd 3.4.4 on the same router with same kernel it is OK

namjaejeon commented 2 years ago

I have tested Nautilus on ubuntu 20.04 version. It work fine on it. This problem is happening on old ubuntu version ?

Yes, I confirm on the ubuntu 20.04 it is ok 3.4.4, but on 18.04 the issue is present

namjaejeon commented 2 years ago

and can you send me debug log after echo all > /sys/class/ksmbd-control/debug ?

namjaejeon commented 2 years ago

ksmbd 3.4.3 mean the version of both ksmbd kernel module and ksmbd-tools is 3.4.3. right ? Because I think that ksmbd kernel module could not build on 4.15 kernel. You are using original ksmbd 3.4.3 version right ?

pesa1234 commented 2 years ago

yes ksmbd and tools 3.4.3 .

Yes original

tcpdump is on the first post

ksmbd is running on openwrt router with kernel 5.4

Okay, I have installed ubuntu 18.04 and tested it. I can't reproduce this issue, it worked fine. Can you give me print log using #ksmbd-debug branch ? git clone --branch=ksmbd-debug https://github.com/namjaejeon/ksmbd
