c38b150ae4 New SCSI target emulator code
This code allows a user program to enable target mode on a SIM and
then emulate any number of devices (disks, tape drives, etc.)  All
decisions about device behavior (UA, CA, inquiry response) are left
to the usermode program and the kernel driver is merely a conduit
for CCBs.  This enables multiple concurrent target emulators, each
using its own backing store and IO model.

Also included is a user program that emulates a disk (RBC) using a
file as a backing store.  This provides functionality similar to
md(4) at the CAM layer.

Code has been tested on ahc(4) and should also work on isp(4) (and
other SIMs that gain target mode support).  It is a complete rewrite
of /sys/cam/scsi_target* and /usr/share/examples/scsi_target.

Use _PATH_* where where possible.

785b6ccaec Don't get stuck in a loop calling exit from an atexit routine. Clean
up cam_fill_ctio usage to passed atio flags. Clear periph_priv area
of new ctio so if the kernel is dumb enough to look at them (this is
a SECURITY hole) the panic will be obvious instead of subtle.

97188b54ce Make use of the new TARGIODEBUG ioctl (i.e., add an option for it's use). 2000-07-14 20:26:59 +00:00

8760939718 Add a cleanup handler called "atexit" to make sure we free up target
mode instances.

Print out exception information passed out from the kernel target mode
driver to this userland daemon.

b3fae35ce8 Allocate a target mode instance to handle our target mode session, clean
it up on exit.  The address for attaching the emulator (path, target id,
lun) is now specified on the command line.  Some attempt at cathing
signals and cleaning up target mode instances is now made.
