[PATCH] s3: introduce new share parameter "open special files"

[Ralph Wuerthner]

Hi list,

attached patch introduces a new share parameter "open special files" to control whether special files such as sockets, devices and fifo's will be opened by the server or not. If set to "no" open requests to special files will fail with "access denied". Default value for "open special files" is "no".

Access to special files impose a security risk because it may for example allow remote clients raw access to local hard drives or kernel memory.

Regards

	Ralph
