NO_GEOM cleanup:
Retire the "d_dump_t" and use the "dumper_t" type instead.
Dumper_t takes a void * as first arg which is more general than the
dev_t taken by d_dump_t. (Remember: we could have net-dumpers if
somebody wrote us one!)
Define the convention for GEOM controlled disk devices to be that the
first argument to the dumper function is the struct disk pointer.

Fix ATAPI/USB/Firewire CDROM drive handling in cd(4) and hopefully fix
a number of related problems along the way.
- Automatically detect CDROM drives that can't handle 6 byte mode
sense and mode select, and adjust our command size accordingly.
We have to handle this in the cd(4) driver (where the buffers are
allocated), since the parameter list length is different for the
6 and 10 byte mode sense commands.
- Remove MODE_SENSE and MODE_SELECT translation removed in ATAPICAM
and in the umass(4) driver, since there's no way for that to work
properly.
- Add a quirk entry for CDROM drives that just hang when they get a 6
byte mode sense or mode select. The reason for the quirk must be
documented in a PR, and all quirks must be approved by
ken@FreeBSD.org. This is to make sure that we fully understand why
each quirk is needed. Once the CAM_NEW_TRAN_CODE is finished, we
should be able to remove any such quirks, since we'll know what
protocol the drive speaks (SCSI, ATAPI, etc.) and therefore whether
we should use 6 or 10 byte mode sense/select commands.
- Change the way the da(4) handles the no_6_byte sysctl. There is
now a per-drive sysctl to set the minimum command size for that
particular disk. (Since you could have multiple disks with
multiple requirements in one system.)
- Loader tunable support for all the sysctls in the da(4) and cd(4)
drivers.
- Add a CDIOCCLOSE ioctl for cd(4) (bde pointed this out a long
time ago).
- Add a media validation routine (cdcheckmedia()) to the cd(4)
driver, to fix some problems bde pointed out a long time ago. We
now allow open() to succeed no matter what, but if we don't detect
valid media, the user can only issue CDIOCCLOSE or CDIOCEJECT
ioctls.
- The media validation routine also reads the table of contents off
the drive. We use the table of contents to implement the
CDIOCPLAYTRACKS ioctl using the PLAY AUDIO MSF command. The
PLAY AUDIO TRACK INDEX command that we previously used was
deprecated after SCSI-2. It works in every SCSI CDROM I've tried,
but doesn't seem to work on ATAPI CDROM drives. We still use the
play audio track index command if we don't have a valid TOC, but
I suppose it'll fail anyway in that case.
- Add _len() versions of scsi_mode_sense() and scsi_mode_select() so
that we can specify the minimum command length.
- Fix a couple of formatting problems in the sense printing code.

The ancient and outdated concept of "privileged ports" in UNIX-type
OSes has probably caused more problems than it ever solved. Allow the
user to retire the old behavior by specifying their own privileged

Now you can run that webserver without ever needing root at all. Or
just imagine, an ftpd that can really drop privileges, rather than
just set the euid, and still do PORT data transfers from 20/tcp.
Two edge cases to note,
# sysctl net.inet.ip.portrange.reservedhigh=0
Opens all ports to everyone, and,
# sysctl net.inet.ip.portrange.reservedhigh=65535

been achieved before with ipfw(8), but is somewhat more
complicated).
For those who stick to the old religion that 0-1023 belong to root and
root alone, don't touch the knobs (or even lock them by raising
securelevel(8)), and nothing changes.

Don't scan lun by myself while boot process leave it CAM to scan the bus.

As a side effect, logical units whose lun is greater than 0 might not be
probed correctly if the lun of 0 doesn't exist in the target because
CAM doesn't scan such luns.
I have a SCSI-FireWire bridge which maps SCSI-ID to LUN and it is an

Make the aac driver be INTR_MPSAFE. Once the interrupt handler determines

o Move the cleanup of the fib maps into aac_free_commands() so as to
retain symetry with aac_alloc_commans(). Since aac_alloc_commands()
allocates fib maps and places them onto the fib lists, aac_free_commands()
should reverse those operations.
o Combine two ifs with the same body with an ||.
o Switch from uintptr_t to uint32_t for fib map load operations.
The target is a uint32_t so using this type for the map load call
avoids an extra cast. uintptr_t should only be used when you need
an "int sized the same as the machine's poitner size" which is not
the case here.
o Removed the commented out M_WAITOK flag in the allocation in
aac_alloc_commands(). The kernel will only block in the allocator
if it can grow the size of the kernel. This usually results in a
page-out which could involve this aac device. Thus, sleeping here
could deadlock the machine. Assuming this operation is occurring outside
of attach time, we have enough fibs to operate anyway, so waiting for
fibs to free up is okay if not optimal.
o In aac_alloc_commands(), if we cannot dmamem_alloc additional fib
space, free the fib map.
o In aac_alloc_commands(), if we cannot create per-command dmamaps, don't
lose track of the fib map that is mapping all of the commands that we
have already released into the free pool. Instead, just cut out of
the loop and modify aac_free_commands to not attempt to free maps that
have not been allocated.
o Don't use a magic number when pre-allocating fibs.
o Use PAGE_SIZE to allocate in page sized chunks instead of an
architecture specific constant.
