.Sh HISTORY
|
|
The
|
|
.Nm
|
|
utility first appeared in
|
|
.Nx 4.0 .
|
|
.Pp
|
|
The
|
|
.Nm
|
|
utility is modeled after a tool of the same name available for Linux from the
|
|
PaX project.
|
|
.Sh BUGS
|
|
.Pp
|
|
The
|
|
.Nm
|
|
utility currently utilizes
|
|
.Xr elf 5
|
|
.Dq note
|
|
sections to mark executables as PaX Segvguard enabled.
|
|
This will be done using
|
|
.Xr fileassoc 9
|
|
in the future so that we can control who does the marking.
