Harden the experimental NFS server a little, by adding range
checks on the length of the client's open/lock owner name. Also,
add free()'s for one case where they were missing and would
have caused a leak if NFSERR_BADXDR had been replied. Probably
never happens, but the leak is now plugged, just in case.
Harden the experimental NFS server a little, by adding extra checks
in the readdir functions for non-positive byte count arguments.
For the negative case, set it to the maximum allowable, since it
was actually a large positive value (unsigned) on the wire.
Also, fix up the readdir function comment a bit.

r205346:
The same code is used to import and to create pool.
The order of operations is the following:
1. Try to open vdev by remembered path and guid.
2. If 1 failed, try to find vdev which guid matches and ignore the path.
3. If 2 failed this means either that the vdev we're looking for is gone
or that pool is being created and vdev doesn't contain proper guid yet.
To be able to handle pool creation we open vdev by path anyway.
Because of 3 it is possible that we open wrong vdev on import which can lead to
confusions.
The solution for this is to check spa_load_state. On pool creation it will be
equal to SPA_LOAD_NONE and we can open vdev only by path immediately and if it
is not equal to SPA_LOAD_NONE we first open by path+guid and when that fails,
we open by guid. We no longer open wrong vdev on import.
r206051:
IOCPARM_MAX defines maximum size of a structure that can be passed
directly to ioctl(2). Because of how ioctl command is build using _IO*()
macros we have only 13 bits to encode structure size. So the structure
can be up to 8kB-1.
Currently we define IOCPARM_MAX as PAGE_SIZE.
This is IMHO wrong for three main reasons:
1. It is confusing on archs with page size larger than 8kB (not really
sure if we support such archs (sparc64?)), as even if PAGE_SIZE is
bigger than 8kB, we won't be able to encode anything larger in ioctl
command.
2. It is a waste. Why the structure can be only 4kB on most archs if we
have 13 bits dedicated for that, not 12?
3. It shouldn't depend on architecture and page size. My ioctl command
can work on one arch, but can't on the other?
Increase IOCPARM_MAX to 8kB and make it independed of PAGE_SIZE and
architecture it is compiled for. This allows to use all the bits on all the
archs for size. Note that this doesn't mean we will copy more on every ioctl(2)
call. No. We still copyin(9)/copyout(9) only exact number of bytes encoded in
ioctl command.
Practical use for this change is ZFS. zfs_cmd_t structure used for ZFS
ioctls is larger than 4kB.

Please welcome HAST - Highly Avalable Storage.
HAST allows to transparently store data on two physically separated machines
connected over the TCP/IP network. HAST works in Primary-Secondary
(Master-Backup, Master-Slave) configuration, which means that only one of the
cluster nodes can be active at any given time. Only Primary node is able to
handle I/O requests to HAST-managed devices. Currently HAST is limited to two
cluster nodes in total.
HAST operates on block level - it provides disk-like devices in /dev/hast/
directory for use by file systems and/or applications. Working on block level
makes it transparent for file systems and applications. There in no difference
between using HAST-provided device and raw disk, partition, etc. All of them
are just regular GEOM providers in FreeBSD.
For more information please consult hastd(8), hastctl(8) and hast.conf(5)
manual pages, as well as http://wiki.FreeBSD.org/HAST.

This is Part III of the great IETF hack-a-thon to fix
the NR-Sack code. (the last one on the cpu options
was a lull.. i.e MFC 205629).. still 2 more to go.
Adds the option of seperating out the sctp stats per
processor. This will be refined further and is definetly
exploratory (which is why its an option) i.e. making it
allocate the actual number of processors is coming ;-D.
