|
.Sh LIBRARY
|
|
|
|
|
used by
|
|
|
|
|
.Xr ld.so 1
|
|
|
|
|
.Sh DESCRIPTION
|
|
|
|
|
The
|
|
|
|
|
.Xr ld.so 1
|
|
|
|
|
runtime linker can be instructed to load
|
|
|
|
|
.Nm
|
|
|
|
|
between the main object and other libraries.
|
|
|
|
|
This enables
|
|
|
|
|
.Nm
|
|
|
|
|
to capture and redirect system call requests to a rump kernel instead
|
|
|
|
|
of the host kernel.
|
|
|
|
|
.Pp
|
|
|
|
|
Currently
|
|
|
|
|
.Nm
|
|
|
|
|
supports only TCP/IP related system calls.
|
|
|
|
|
The set of supported subsystems may change later along with the usage
|
|
|
|
|
of the library.
|
|
|
|
|
.Sh EXAMPLES
|
|
|
|
|
Use an alternate TCP/IP stack for firefox:
|
|
|
|
|
.Bd -literal -offset indent
|
|
|
|
|
$ setenv RUMP_SERVER unix:///tmp/tcpip
|
|
|
|
|
$ setenv LD_PRELOAD /usr/lib/librumphijack.so
|
|
|
|
|
$ firefox
