error 1
gptzfsboot: error 1 lba 4294967288
gptzfsboot: error 1 lba 1
gptzfsboot: no ZFS pools located, can't boot
The first two errors above are from issuing INT13 EAX=0x4800, meaning we
need to check if EDD is available and use EAX=0x800 if not.
For an workaround I'm using the similar idea as in biosdisk.c - first probe
ah=8h, then check if we have EDD.
Note we would like to see the correct disk size info, but we *may*
get away with anything >64MB, so we could at least test 2 zfs pool labels
on whole disk setup and not to freak out the INT13 interface.
If we get away with initial disk probing, then we have partition sizes from
the partition table and we should be able to complete the disk probing.
Note: this update does not provide full fix to all errors, but we get
the drvsize() errors removed.

Extended attributes and their particular implementation in linux are
different from FreeBSD so in this case we have started diverging from
the UFS EA implementation, which would be the natural reference.
Depending on future progress implementing ACLs this approach may change
but for now bring to the tree an implementation that is consistent and
can be tested.

After FreeBSD SVN revision 236814, the pass(4) driver changed from
only doing error recovery when the CAM_PASS_ERR_RECOVER flag was
set on a CCB to sometimes doing error recovery if the passed in
retry count was non-zero.
Error recovery would happen if two conditions were met:
1. The error recovery action was simply a retry. (Which is most
cases.)
2. The retry_count is non-zero. (Which happened a lot because of
cut-and-pasted code.)
This explains a bug I noticed in with camcontrol:
# camcontrol tur da34 -v
Unit is ready
# camcontrol reset da34
Reset of 1:172:0 was successful
At this point, there should be a Unit Attention:
# camcontrol tur da34 -v
Unit is ready
No Unit Attention.
Try it again:
# camcontrol reset da34
Reset of 1:172:0 was successful
Now set the retry_count to 0 for the TUR:
# camcontrol tur da34 -v -C 0
Unit is not ready
(pass42:mps1:0:172:0): TEST UNIT READY. CDB: 00 00 00 00 00 00
(pass42:mps1:0:172:0): CAM status: SCSI Status Error
(pass42:mps1:0:172:0): SCSI status: Check Condition
(pass42:mps1:0:172:0): SCSI sense: UNIT ATTENTION asc:29,2 (SCSI bus reset occurred)
(pass42:mps1:0:172:0): Field Replaceable Unit: 2
There is the unit attention. camcontrol(8) has a default
retry_count of 1, in case someone sets the -E flag without
setting -C.
The CAM_PASS_ERR_RECOVER behavior was only broken with the
CAMIOCOMMAND ioctl, which is the synchronous pass(4) API. It has
worked as intended (error recovery is only done when the flag
is set) in the asynchronous API (CAMIOQUEUE ioctl).
sys/cam/scsi/scsi_pass.c:
In passsendccb(), when calling cam_periph_runccb(), only
specify the error routine when CAM_PASS_ERR_RECOVER is set.

name and unit number in camcontrol(8).
Previously camcontrol(8) only supported rescanning or resetting
devices specified by bus:target:lun. This is because for
rescanning at least, you don't have a peripheral name and unit
number (e.g. da4) for devices that don't exist yet.
That is still the case after this change, but in other cases, when
the device does exist in the CAM EDT (Existing Device Table), we
do a careful lookup of the bus/target/lun if the user supplies a
peripheral name and unit number to find the bus:target:lun and then
issue the requested reset or rescan.
The lookup is done without actually opening the device in question,
since a rescan is often done to make a device go away after it has
been pulled. (This is especially true for busses/controllers, like
parallel SCSI controllers, that don't automatically detect changes
in topology.) Opening a device that is no longer there to
determine the bus/target/lun might result in error recovery actions
when the user really just wanted to make the device go away.
sbin/camcontrol/camcontrol.c:
In dorescan_or_reset(), if the use hasn't specified a
numeric argument, assume he has specified a device. Lookup
the pass(4) instance for that device using the transport
layer CAMGETPASSTHRU ioctl. If that is successful, we can
use the returned bus:target:lun to rescan or reset the
device.
Under the hood, resetting a device using XPT_RESET_DEV is
actually sent via the pass(4) device anyway. But this
provides a way for the user to specify devices in a more
convenient way, and can work on device rescans when the
device is going away, assuming it still exists in the EDT.
sbin/camcontrol/camcontrol.8:
Update the man page for the rescan and reset subcommands
to reflect that you can now use a device name and unit
number with them.

vnet_pf_uninit() is called through vnet_deregister_sysuninit() and
linker_file_unload() when the pf module is unloaded. This is executed
after pf_unload() so we end up trying to take locks which have been
destroyed already.
Move pf_unload() to a separate SYSUNINIT() to ensure it's called after
all the vnet_pf_uninit() calls.

Prior to this change, the CRN (Command Reference Number) is reset on any
firmware LIP, LOOP DOWN, or LOOP RESET event in violation of FCP-4 which
specifies that the CRN should only be reset in response to a LIP Reset
(LIPyx) primitive. FCP-4 also indicates PLOGI/LOGO and PRLI/PRLO ELS
actions as conditions for resetting the CRN for the associated initiator
port.
These violations manifest themselves when the HBA is removed from the
loop, or a target device is removed (especially during an outstanding
command) without power cycling. If the HBA and and the target device
determine upon re-establishing the loop that no PLOGI or PRLI is
required, and the target does not issue a LIPxy to the initiator, the
CRN for the target will have been improperly reset by the isp driver. As
a result, the target port will silently ignore all FCP commands issued
during the device probe (which will time out) preventing the device from
attaching.
This change corrects thie CRN reset behavior in response to loop state
changes, also introduces CRN resets for the above mentioned ELS actions
as encountered through async PDB change events.
This change also adds cleanup of outstanding commands in isp_loop_dead()
that was previously missing.

wlanwds monitors the physical interface for DWDS requests from VAPs,
but the clone is created against the physical interface. So, if you
have a secondary VAP setup (with a separate, non-physical-default MAC
address) which is configured for DWDS, the temporary DWDS VAPs created
will have the MAC of the parent physical interface and NOT the
actual cloned interface + MAC.
This .. stumped me for a few minutes.
Maybe I'll fix it. Maybe I won't. At least I now have DWDS+encryption
working at home.
Tested:
