Package: samba
Version: 2:4.1.17+dfsg-2
Severity: important
Tags: upstream
Dear Maintainer,
* What led up to the situation?
I have received 5 panic action emails from samba recently.
I installed gdb and samba-dbg as suggested in the emails
to get a stacktrace. The panics have only happened for a
single user (there are only a few) and I think that it only
happens when they are connected to the LAN via openvpn
but I'm not entirely sure of that. The openvpn server is a
different host which is masquerading openvpn traffic. The
fact that this is the only user that does connect via openvpn
and uses samba might be relevant. However, there seems to be
no other issues involving openvpn so it may not be relevant.
I have just upgraded from debian7 to debian8 but I think that
the samba that was installed was a backport (I didn't install it)
so It's probably that the version of samba didn't change with
the upgrade.
The first panic email was just before the upgrade to debian8.
Also, I recently changed the smb.conf to be more "secure" in
accordance with the instructions from Rapid7's Nexpose
vulnerability scanner. One of the changes that may or may not
be relevant is that all packets are being signed.
* What exactly did you do (or not do) that was effective (or
ineffective)?
I just asked the user if they noticed a problem. They said that
the everything on the mapped drive disappeared and when they
disconnect and recommect, the files came back. I warned them
that this is likely to continue and to repeat their workaround
when it does.
* What was the outcome of this action?
* What outcome did you expect instead?
