afaict the STATUS_INVALID_PARAMETER comes from the lease code as you're
passing the same lease key for the open on the link which is illegal afair.
Can you retry the experiment without requesting a lease or ensuring the
second open on the link uses a different lease key?
Indeed, the same lease key is coming in both opens, first in
packet 3 where it opens "test", and again in packet 18 where
it opens the link "new". So it's triggering this assertion in
MS-SMB2 section 3.3.5.9.11
The server MUST attempt to locate a Lease by performing a lookup in the LeaseTable.LeaseList
using the LeaseKey in the SMB2_CREATE_REQUEST_LEASE_V2 as the lookup key. If a lease is found,
Lease.FileDeleteOnClose is FALSE, and Lease.Filename does not match the file name for the
incoming request, the request MUST be failed with STATUS_INVALID_PARAMETER
Steve/Rohith, is this new behavior in the client code?
