Stefan Metzmacher	6fa753a1a6	smbd: add vfs_valid_{pread,pwrite}_range() checks where needed ... I checked all callers of SMB_VFS_PWRITE[_SEND](), all callers of SMB_VFS_PREAD[_SEND]() and also places where we append to the file and allocate more space.

Stefan Metzmacher	54de0e4a3e	s4:torture: add tests to test the SMB2 read/write offset/length boundaries ... [MS-FSA] 2.1.5.2 Server Requests a Read and 2.1.5.3 Server Requests a Write define some contraints. These tests demonstrate that ((int64_t)offset) < 0) is not allowed for both reads and writes for SMB. Also the special case for writes at offset -2 is not possible nor the append mode with offset < 0.
