- Commit work from libprocstat project. These patches add support for runtime

Browse Source 
file and processes information retrieval from the running kernel via sysctl
  in the form of new library, libprocstat.  The library also supports KVM backend
  for analyzing memory crash dumps.  Both procstat(1) and fstat(1) utilities have
  been modified to take advantage of the library (as the bonus point the fstat(1)
  utility no longer need superuser privileges to operate), and the procstat(1)
  utility is now able to display information from memory dumps as well.

  The newly introduced fuser(1) utility also uses this library and able to operate
  via sysctl and kvm backends.

  The library is by no means complete (e.g. KVM backend is missing vnode name
  resolution routines, and there're no manpages for the library itself) so I
  plan to improve it further.  I'm commiting it so it will get wider exposure
  and review.

  We won't be able to MFC this work as it relies on changes in HEAD, which
  was introduced some time ago, that break kernel ABI.  OTOH we may be able
  to merge the library with KVM backend if we really need it there.

.Dt KINFO_GETALLPROC 3
.Sh NAME
.Nm kinfo_getallproc
.Nd function for getting process information of all processes from kernel
.Sh LIBRARY
.Lb libutil
.Sh SYNOPSIS
.In sys/types.h
.In libutil.h
.Ft struct kinfo_proc *
.Fn kinfo_getallproc "int *cntp"
.Sh DESCRIPTION
This function is used for obtaining process information of all processes from
the kernel.
.Pp
The
.Ar cntp
field is a pointer containing the number of process structures returned.
This function is a wrapper around
.Xr sysctl 3
with the
.Dv KERN_PROC_PROC
mib.
While the kernel returns a packed structure, this function expands the
data into a fixed record format.
.Sh RETURN VALUES
On success the
.Fn kinfo_getallproc
function returns a pointer to
.Ar cntp
.Vt struct kinfo_proc
structures as defined by
.In sys/user.h .
The pointer was obtained by an internal call to
.Xr malloc 3
and must be freed by the caller with a call to
.Xr free 3 .
On failure the
.Fn kinfo_getallproc
function returns
.Dv NULL .
.Sh SEE ALSO
.Xr free 3 ,
.Xr malloc 3 ,
.Xr sysctl 3

While the kernel returns a packed structure, this function expands the
data into a fixed record format.
.Sh RETURN VALUES
On success the
.Fn kinfo_getproc
function returns a pointer to a
.Vt struct kinfo_proc
structure as defined by
.In sys/user.h .
The pointer was obtained by an internal call to
.Xr malloc 3
and must be freed by the caller with a call to
.Xr free 3 .
On failure the
.Fn kinfo_getproc
function returns
.Dv NULL .
.Sh SEE ALSO
.Xr free 3 ,
.Xr malloc 3 ,
.Xr sysctl 3

.Os
.Sh NAME
.Nm fuser
.Nd list IDs of all processes that have one or more files open
.Sh SYNOPSIS
.Nm
.Op Fl cfkmu
.Op Fl M Ar core
.Op Fl N Ar system
.Op Fl s Ar signal
.Op Ar
.Sh DESCRIPTION
The
.Nm
utility writes to stdout the PIDs of processes that have one or
more named files open.
For block and character special devices, all processes using files
on that device are listed.
A file is considered open by a process if it was explicitly opened,
is the working directory, root directory, jail root directory,
active executable text, kernel trace file or the controlling terminal
of the process.
If
.Fl m
option is specified, the
.Nm
utility will also look through mmapped files.
.Pp
The following options are available:
.Bl -tag -width indent
.It Fl c
Treat files as mount point and report on any files open in the file system.
.It Fl f
The report must be only for named files.
.It Fl k
Send signal to reported processes
.Pq SIGKILL by default .
.It Fl m
Search through mmapped files too.
.It Fl u
Write the user name associated with each process to stdout.
.It Fl M
Extract values associated with the name list from the specified core
instead of the default
.Pa /dev/kmem .
.It Fl N
Extract the name list from the specified system instead of the default,
which is the kernel image the system has booted from.
.It Fl s
Use given signal name instead of default SIGKILL.
.El
.Pp
The following symbols, written to stderr will indicate how files is used:
.Bl -tag -width MOUNT
.It Cm r
The file is the root directory of the process.
.It Cm c
The file is the current workdir directory of the process.
.It Cm j
The file is the jail-root of the process.
.It Cm t
The file is the kernel tracing file for the process.
.It Cm x
The file is executable text of the process.
.It Cm y
The process use this file as its controlling tty.
.It Cm m
The file is mmapped.
.It Cm w
The file is open for writing.
.It Cm a
The file is open as append only
.Pq O_APPEND was specified .
.It Cm d
The process bypasses fs cache while writing to this file
.Pq O_DIRECT was specified .
.It Cm s
Shared lock is hold.
.It Cm e
Exclusive lock is hold.
.El
.Sh EXIT STATUS
The
.Nm
utility returns 0 on successful completion and >0 otherwise.
.Sh EXAMPLES
The command:
.Dq Li "fuser -fu ."
writes to standart output the process IDs of processes that are using the
current directory and writes to stderr an indication of how those processes are
using the direcory and user names associated with the processes that are using
this directory.
.Sh SEE ALSO
.Xr fstat 1 ,
.Xr ps 1 ,
.Xr systat 1 ,
.Xr iostat 8 ,
.Xr pstat 8 ,
.Xr vmstat 8
.Sh STANDARTS
The
.Nm
utility is expected to conform to
.St -p1003.1-2004 .
.Sh BUGS
Since
.Nm
takes a snapshot of the system, it is only correct for a very short period
of time.
When working via
.Xr kvm 3
interface the report will be limited to filesystems the
.Nm
utility knows about (currently only cd9660, devfs, nfs, ntfs, nwfs, udf,
ufs and zfs).
.Sh AUTHORS
The
.Nm
utility and this manual page was written by
.An Stanislav Sedov Aq stas@FreeBSD.org .
