folders becoming files with Ksmbd: 3.3.4 Kmod: 3.3.5

folders becoming files with Ksmbd: 3.3.4 Kmod: 3.3.5 on OpenWrt SNAPSHOT r15899-567a88e4b9 / LuCI Master git-21.050.34860-b8d2bcd on kirkwood Feroceon 88FR131 rev 1 (v5l) on a ZyXEL NSA310S
copying with a cp from console is ok, but copying with GNOME nautilus 3.38.1 on ubuntu make folders beeing files at last.
I have to remove the dos attribute manually to access the folders as folders again.
find . -type d -exec setfattr -x user.DOSATTRIB "{}" ;

I get also some kernel error logged while accessing (copying or deleting) :
[ 1765.711828] ksmbd: ndr_decode_dos_attr:180: v0 version is not supported
[ 1765.741612] ksmbd: ndr_decode_dos_attr:180: v0 version is not supported
[ 1765.757393] ksmbd: ndr_decode_dos_attr:180: v27695 version is not supported

Ah, Are you saying that both 3.3.4 and 3.3.5 are problems? Or are the directories created in 3.3.4 appearing as a file in 3.3.5?

[erdoukki]

Both 3.3.4 and 3.3.5 are problems.
The copied directories appears as files at the end of the copy process on both version

[namjaejeon]

Have you ever reproduce this issue with ksmbd 3.3.3 version ? Nautilus rsend a request to change directory to file using smb2 set info command. I added exception code to protect it. maybe, This change will include in 3.3.6 version.

[erdoukki]

I am new user of ksmbd so I haven't tested 3.3.3.
I will wait for 3.3.6 and give you feedback about it...

[namjaejeon]

Sure, I will share 3.3.6 version release soon.
I think that there is same issue in old ksmbd version. and nautilus seems to send wrong command to server. anyway. Thanks for your report to fix it!

[namjaejeon]

I have released ksmbd/ksmbd-tools 3.3.6 version. But You may wait for ksmbd package release by @Andy2244 or @neheb if you don't know how ksmbd can be manually installed on OpenWRT.

[mrkiko]

What I would try is to manually compile the kernel module with OpenWRt toolchain.

May I ask you to write down some instructions?
What I would do is using openwrt/staging_dir toolchain, playing with CROSS_COMPILE_?? stuff, and so on.

[namjaejeon]

@neheb Could you please answer @mrkiko 's question ?

[neheb]

I don't fully understand it. Compiling ksmbd for OpenWrt just takes running make menuconfig , selecting ksmbd , and running make

[Andy2244]

I don't fully understand it. Compiling ksmbd for OpenWrt just takes running make menuconfig , selecting ksmbd , and running make

I think they ask how to create and compile 3.3.6 version, so they don't have to wait for the snapshot PR. If you can update again this would be nice, since samba-4.14 was just released and thats where i will spend my spare free time next.

Do you prefer I open a new issue ?

[mmakassikis]

errno code = -2 is ENOENT.
Verify the share's name is correct and that the path is points exists. Same on the client side: does /mnt/test exist ?
Have you checked network connectivity ? Can you ping the OpenWRT host ?
On the OpenWRT host, verify using netstat or ss (I don't know what OpeenWRT includes) that there is a socket bound on port 445 by the ksmbd kernel module and not samba.

[erdoukki]

share name ok (not changed from latest tests)
local folder name ok
ping ok and access ssh and web ok

no debug possibilities (missing tools from openwrt package)
