Message-ID<yf3rP-3Au-1@gated-at.bofh.it>
Package: src:linux
Version: 4.9.168-1+deb9u3
Severity: important

Dear Maintainer,

after upgrading to the latest linux-image-adm64 on stretch we're experiencing strange issues on a 
fileserver with samba: directory listings in subfolder of shares don't work after upgrading to 
4.9.168-1+deb9u3 on the clients. I've rebooted the machine to linux-image-4.9.0-8-amd64 - with that 
version everything is working. 

So I'm wondering if there are other users which experience similar problems with the latest 
kernel and samba? 

Thanks,
Werner

There is a known regression that will be fixed soon, affecting programs
that use small socket buffers.

I think it was once recommended to set the SO_SNDBUF parameter in
smb.conf, which can trigger this bug.  This parameter is now
deprecated, and if it is present in your configuration file it should
be safe to remove it.

Please let us know if that change fixes the issue.

Ben.

Any sufficiently advanced bug is indistinguishable from a feature.

ACK, removing SO_SNDBUF from smb.conf indeed fixed the problem :)

Thanks,
