Notes:
|
|
|
|
The SMB mini redirector manipulates entities which have very different usage patterns.
|
|
They range from very static entities ( which are allocated and freed with a very low
|
|
frequency ) to very dynamic entities.
|
|
|
|
The entities manipulated in the SMB mini redirector are SMBCE_SERVER, SMBCE_NET_ROOT,
|
|
SMBCE_VC, SMBCE_SESSION. These represent a connection to a server, a share on a particular
|
|
server, a virtual circuit used in the connection and a session for a particular user.
|
|
|
|
These are not very dynamic, i.e., the allocation/deallocation is very infrequent. The
|
|
SMB_EXCHANGE and SMBCE_REQUEST map to the SMB's that are sent along that a connection.
|
|
Every file operation in turn maps to a certain number of calls for allocationg/freeing
|
|
exchanges and requests. Therefore it is imperative that some form of scavenging/caching
|
|
of recently freed entries be maintained to satisfy requests quickly.
|
|
|
|
In the current implementation the exchanges and requests are implemented using the zone
|
|
allocation primitives.
