Hi,
I'm trying to switch from ntlpssp to kerbebos for mounting our dfs
shares. It seems to work, but only for 'older' kernel versions. Since we
are running debian 9 and 10, I'm testing this for both version. The
thing is that is seems to work when I run kernel 4.19.67, but not when
I'm running kernel 5.3.9.
What I'm trying to do:
mount -t cifs //domain.com/common /mnt/common -o
rw,vers=3.0,sec=krb5,cruid=10003,username=mdg,uid=10003,gid=10276,addr=10.1.1.14,file_mode=0600,dir_mode=0700,nobrl,nohandlecache,user=mdg
So far it works fine on 4.19, but not on 5.3. Because when I try to
travel into the directories (which are actually dfs pointers to the NAS
shares) I get permission denied.
So far, I was able to track this down to cifs.upcall, because on kernel
4.19 I see it tries to get a service ticket for the nas (cifs.upcall:
handle_krb5_mech: getting service ticket for nas01.domain.com). But on
kernel 5.3 it tries to get a ticket for the dc again: cifs.upcall:
handle_krb5_mech: getting service ticket for dc01.domain.com.
What could be wrong here?

I tried kernel 5.4.6, including this fix, but still no luck:

Thanks for testing it.
Could you post dmesg output of both versions with debugging enabled as per
instructions in [1]?
Thanks,
Paulo

I attached the traces for kernel 4.19 and 5.4, I try to access the subdirectory after the '=====' separator in the log.
I looks like in the past a different sesInfo was passed to cifs_get_spnego_key().

Thanks for the logs!
I noticed that we're passing a wrong value for "ip=" down to cifs_mount():
[ 58.731307] fs/cifs/cifs_spnego.c: key description = ver=0x2;host=DC01.Prodrive.nl;ip4=10.1.1.6;sec=krb5;uid=0x2713;creduid=0x2713;user=mdg;pid=0x60b
That is,
10.1.1.6 -> str02
10.1.1.14 -> DC01.Prodrive.nl
which means that ip option should be set to 10.1.1.14.
cifs_mount() will not attempt to resolve the hostname in case we have a
_valid_ ip address set in the mount options, so we end up connecting to
the wrong server (str02) and then failing to authenticate.
Well, we could simply set "devname" to the resolved target (str02) and
we're done with it, but the problem with that is that it will break DFS
failover - that is, we will not be able to retry the other targets in
the referral in case we failed to connect it in cifs_mount().
I'm not entirely sure if that's the problem you're facing, but could you
please try below changes?
Thanks,
Paulo

Thanks for testing it!
So far so good?
Let me know so I can prepare a patch for upstream.
Thanks,

Yes, so far so good. Thanks a lot for the quick response! Not a trivial
patch as far I as i can judge.
Also the machine we have running with your other DFS patches is running
for 8 weeks now and survived several relocations of our dfs shares and
adding/removal of DCs!
Is there any news on the acceptance of your [PATCH v4 0/6] DFS fixes?
Regards, Martijn

Cool! Thanks for the confirmation. Just sent a patch with this fix, BTW.

I don't have any news, but I'll talk to Steve and Aurelien about them.

Hello Paulo,
I ran into this issue and noted that I can reproduce this 100% of the
time with a Samba SMB target. I tried with Windows SMB targets, even
when they are not part of the direct DFS namespace, but I have so far
been unable to reproduce that way.
Hello Martijn,
Would you mind stating who the provider is for the impacted SMB target
in your environment?
Thanks,
Jacob

I missed that.
I just checked again and I completely overlooked this.
Sorry for the confusion.
