Hi Ralph:
I ran all your test cases where first create is PH with sharing mode none and 
Lease request R. Those were test cases 1,21,41,61,81 and 101 and in all cases 
the epoch is increased in the create response, although your test output 
declares 

" ../../source4/torture/smb2/durable_v2_open.c:6270: Expression `lease_ok' 
failed: Bad lease epoch".

Hi Ralph:
What is the test case for this scenario in smbtorture? I imagined it is in 
smb2.persistent-open.reconnect-contended.

Hi Slow,

Thanks for reaching out with your Persistent Handle question. I've created case 
2508130040006013 to track the issue. One of our engineers will investigate this 
and reach out to you soon.

Subject: [EXTERNAL] MS-SMB2: Disconnected PH looses R lease without epoch bump

Hi dochelp!

Here comes another one related to Persistent Handles...

I see the following behaviour against a Windows server with Fileserver for 
General Use role:

1. Client 1 opens file with PH, lease=R and sharemode=none 2. Client 1 
disconnects TCP connection 3. Client 2 tries to open file and gets 
STATUS_FILE_NOT_AVAILABLE 4. Client 1 reconnects SMB 5. Client 1 reconnects PH, 
this succeeds but the lease is downgrade to NONE but the lease epoch is still 
the same as in step 1, iow it is not bumped

Is this expected behaviour?

There's footnote 247 in "3.3.4.7 Object Store Indicates a Lease Break" 
but none of the cases described there seem to cover my scenario.

According to the SDC presentation "SMB 2.2 : Bigger, Faster, Scalier (Part 2)" 
from 2011, page 50, the server must bump the lease epoch.

Can you please clarify?

Traces (pcap + t.cmd) available.

Thanks!
