files disappear after being copied from macOS about ksmbd

[namjaejeon]

I am on Linux kernel 6.7 on Debian trixie/testing, which seems to be running ksmbd 3.4.2. (Why so old?)

I didn't update ksmbd version in linux mainline. because there is version number of linux kernel. and I have remove versioning on 6.9 kernel. This issue is coming with only MacOS client ? No reproducible with windows client and linux clients ?

Can you test it after installing github ksmbd ?

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

Thanks.

It seems to work fine on the Windows client.

I did also notice that the test file, when finally written (it seems to sometimes work after several tries which is confusing) is in a strange mode where I cannot read it. Both Mac and Windows tell me I do not have permission. The file is owned properly, can be accessed OK on the host (Linux) and has permissions set OK (664).

because 6.7.12 kernel doesn't have this patch. It is related with MacOS client.

If you give me wireshark(or tcpdump) file that captured packets on problem situation to me, I will find the clue.
