other mechanisms are used described in more detail below.
Path processing in Samba typically means processing client supplied paths
- by Samba's core path processing function `filename_convert()' which returs
+ by Samba's core path processing function `filename_convert()' which returns
a pointer to an object of type `struct smb_filename'. Pointers to such
objects are then passed around, often passing many layers of code.
In Samba the decision whether to call POSIX `open()' on a client pathname
or whether to leave the low-level handle at -1 (what we call a stat-open)
- is based on the client requested SMB acccess mask.
+ is based on the client requested SMB access mask.
The set of access rights that trigger an `open()' includes
`READ_CONTROL_ACCESS'. As a result, the open() will be done with at least

The way this is implemented on such systems is impersonating the root user
- for the `open()' syscall. In order to avoid privelege escalations security
+ for the `open()' syscall. In order to avoid privilege escalations security
issues, we must carefully control the use these file-handles.
The low level filehandle is stored in a public struct `struct file_handle'
that is part of the widely used `struct files_struct'. Consumers used to
- simply access the fd directly by derefencing pointers to `struct
