.Sh DESCRIPTION
|
|
|
|
|
The Linux process file system, or
|
2000-11-20 18:41:33 +00:00
|
|
|
.Nm ,
|
2000-03-25 14:03:31 +00:00
|
|
|
emulates a subset of Linux' process file system and is required for
|
|
|
|
|
the complete operation of some Linux binaries.
|
|
|
|
|
.Pp
|
|
|
|
|
The
|
|
|
|
|
.Nm
|
|
|
|
|
provides a two-level view of process space.
|
|
|
|
|
At the highest level, processes themselves are named, according to
|
|
|
|
|
their process ids in decimal, with no leading zeros. There is also a
|
|
|
|
|
special node called
|
|
|
|
|
.Pa self
|
|
|
|
|
which always refers to the process making the lookup request.
|
|
|
|
|
.Pp
|
|
|
|
|
Each node is a directory which contains the following entries:
|
|
|
|
|
.Pp
|
|
|
|
|
Each directory contains several files:
|
|
|
|
|
.Bl -tag -width status
|
|
|
|
|
.It Pa exe
|
|
|
|
|
A reference to the vnode from which the process text was read.
|
|
|
|
|
This can be used to gain access to the process' symbol table,
|
|
|
|
|
or to start another copy of the process.
|
|
|
|
|
.It Pa mem
|
|
|
|
|
The complete virtual memory image of the process.
|
|
|
|
|
Only those addresses which exist in the process can be accessed.
|
|
|
|
|
Reads and writes to this file modify the process.
|
|
|
|
|
Writes to the text segment remain private to the process.
|
|
|
|
|
.El
|
|
|
|
|
.Pp
|
|
|
|
|
Each node is owned by the process's user, and belongs to that user's
|
|
|
|
|
primary group, except for the
|
|
|
|
|
.Pa mem
|
|
|
|
|
node, which belongs to the
|
|
|
|
|
.Li kmem
|
|
|
|
|
group.
