- Rename $kerberos5_server_enable with $kdc_enable and rename
rc.d/kerberos with rc.d/kdc.
- Rename $kadmin5_server_enable with $kadmind_enable.
- Rename ${kerberos5,kpasswdd}_server with ${kdc,kpasswdd}_program.
- Fix rc.d/{kadmind,kerberos,kpasswdd,kfd} scripts not to change variables
after load_rc_config().
- Add rc.d/ipropd_master and rc.d/ipropd_slave scripts. These are
for iprop-master(8) and iprop-slave(8). Keytab used for iprop service is
defined in ipropd_{master,slave}_keytab (/etc/krb5.keytab by default).
- Add dependency on rc.d/kdc to SERVERS. rc.d/kdc must be invoked as early
as possible before scripts divided by rc.d/SERVERS.
Note that changes to rc.d/{kdc,kpasswdd,kadmind} are backward-compatible
with the old configuration variables:
${kerberos5,kpasswdd,kadmin5}_server{,_enable,_flags}.
Prior to this change we triggered ARC reclaim when kmem usage passed 3/4
of the total available, as indicated by vmem_size(kmem_arena, VMEM_ALLOC).
This could lead large amounts of unused RAM e.g. on a 192GB machine with
ARC the only major RAM consumer, 40GB of RAM would remain unused.
The old method has also been seen to result in extreme RAM usage under
certain loads, causing poor performance and stalls.
We now trigger ARC reclaim when the number of free pages drops below the
value defined by the new sysctl vfs.zfs.arc_free_target, which defaults
to the value of vm.v_free_target.

libraries that need to be linked into an executable or library have to be
listed on the command line explicitly. This commit fixes a bug in ld(1)
where it would scan dependencies of the libraries on the command line and
link them if needed if they were also found in ld.so.cache.
The important bit of the patch is the initialisation of needed.by such that
libraries found by scanning dependencies are marked as such and not used in
the link.

but has some retries.
Without this, single frame transmission in AMPDU will always look like
it succeeded fine, and thus AMRR will think it's totally fine to just
keep upping the rate upwards.
Now, this is still not quite right! For multi-frame aggregates the
completion happens in two parts - the TX done and the BA received.
The driver is currently double accounting those a little - there's no
way to say to the rate control code "I completed X frames, Y worked fine,
there were Z retries." And it's a bit odd with iwn, as the firmware
retransmits frames for us so we don't get to see how many retransmits
happened; only that it took longer than normal. I may have to extend
the rate control API to properly track that.
So this may keep the rate lower than it should be, but that's better
than keeping it higher than it should be.
Tested:
* 5100, STA mode
in preparation for the 5300 3x3 NIC.
During this particular adventure, I did indeed discover that a whole
swath of things made little to no sense.
Those included, and are fixed here:
* A lot of the antenna configuration bits assume the NIC has two receive
chains. That's blatantly untrue for NICs that don't.
* There was some disconnect between the antenna configuration when
forming a PLCP rate DWORD (which includes the transmit antenna
configuration), separate to the link quality antenna configuration.
So now there's helper functions to return which antenna configurations
to use and those are used wherever an antenna config is required.
* The 5300 does up to three stream TX/RX (so MCS0->23), however
the link quality table has only 16 slots. This means all of the
rate entries are .. well, dual-stream rates. If this is the case,
the "last MIMO" parameter can't be 16 or it panics the firmware.
Set it to 15.
* .. and since yes it has 16 slots, it only would try retransmitting
from MCS8->MCS23, which can be quite .. terrible. Hard-code the last
two retry slots to be the lowest configured rate.
* I noticed some transmit configuration command stuff is different
based on firmware API version, so I lifted that code from Linux.
* Add / augment some more logging to make it easier to capture this
stuff.
Now, 3x3 is still terrible because the link quality configuration is
plainly not good enough. I'll have to think about that.
However, the original goal of this - 3x3 operation on the Intel
5300 NIC - actually worked.
There are also rate control bugs in the way this driver handles
notifying the net80211 rate control code when AMPDU is enabled.
It always steps the rate up to the maximum rate possible - and
this eventually ends in much sadness. I'll fix that later.
As a side note - 2GHz HT40 now works on all the NICs I have tested.
As a second side note - this exposed some bad 3x3 behaviour in
the ath(4) rate control code where it starts off at a 3-stream rate
and doesn't downgrade quickly enough. This makes the initial
dhcp exchange take a long time. I'll fix the ath(4) rate code
to start at a low fixed 1x1 MCS rate and step up if everything
works out.

There were two issues:
1. The area given to vt_is_cursor_in_area() was adding the drawable
area offset, something already handled by this function.
2. The cursor was shifted on the screen by the offset of this area
and thus was misplaced or not erased. Furthermore, when reaching
the bottom or right borders, the cursor was either totally
removed or not erased correctly.

There's still room for improvement. For instance, we should not mark a
