e7926a3703 Reimplemented "gpart destroy -F". Now it does all work in kernel.
This was needed for recover implementation.

Implement the recover command for GPT. Now GPT will marked as
corrupt when any of three types of corruption will be detected:
1. Damaged primary GPT header or table
2. Damaged secondary GPT header or table
3. Secondary header is not located in the last LBA
Marked GPT becomes read-only. Any changes with corrupt table
are prohibited. Only "destroy" and "recover" commands are allowed.

5ad4a7c74a Bring in geli suspend/resume functionality (finally).
Before this change if you wanted to suspend your laptop and be sure that your
encryption keys are safe, you had to stop all processes that use file system
stored on encrypted device, unmount the file system and detach geli provider.

This isn't very handy. If you are a lucky user of a laptop where suspend/resume
actually works with FreeBSD (I'm not!) you most likely want to suspend your
laptop, because you don't want to start everything over again when you turn
your laptop back on.

And this is where geli suspend/resume steps in. When you execute:

	# geli suspend -a

geli will wait for all in-flight I/O requests, suspend new I/O requests, remove
all geli sensitive data from the kernel memory (like encryption keys) and will
wait for either 'geli resume' or 'geli detach'.

Now with no keys in memory you can suspend your laptop without stopping any
processes or unmounting any file systems.

When you resume your laptop you have to resume geli devices using 'geli resume'
command. You need to provide your passphrase, etc. again so the keys can be
restored and suspended I/O requests released.

Of course you need to remember that 'geli suspend' won't clear file system
cache and other places where data from your geli-encrypted file system might be
present. But to get rid of those stopping processes and unmounting file system
won't help either - you have to turn your laptop off. Be warned.

Also note, that suspending geli device which contains file system with geli
utility (or anything used by 'geli resume') is not very good idea, as you won't
be able to resume it - when you execute geli(8), the kernel will try to read it
and this read I/O request will be suspended.

6305a96c20 Implement "force" (-F) option for gpart destroy verb.
This option doesn't passed to kernel and handled in user-space.
With -F option gpart creates new "delete" request for each
partition in table. Each request has flags="X" that disables
auto-commit feature. Last request is the original "destroy" request.
It has own flags and can have disabled or enabled auto-commit feature.
If error is occurred when deleting partitions, then new "undo" request
is created and all changes will be rolled back.

044bf69fd5 Add a geli resize subcommand to resize encrypted filesystems prior
to growing the filesystem.

Refuse to attach providers where the metadata provider size is
wrong.  This makes post-boot attaches behave consistently with
pre-boot attaches.  Also refuse to restore metadata to a provider
of the wrong size without the new -f switch.  The new -f switch
forces the metadata restoration despite the provider size, and
updates the provider size in the restored metadata to the correct
value.

2b4969ff9e Change how multipath labels are created and managed. This makes it easier
to support various storage boxes which really aren't active-active.

We only write the label on the *first* provider. For all other providers
we just "add" the disk. This also allows for an "add" verb.

A usage implication is that you should specificy the currently active
storage path as the first provider.

Note that this does not add RDAC-like functionality, but better allows for
autovolumefailover configurations (additional checkins elsewhere will support
this).

when trees were big and FAST mode was enabled by default.

So small block size doesn't benefits linear I/O operations in FAST and
significantly slowdowns in ECONOMIC (default) mode. For single stream random
I/Os so small block doesn't give much benefits, as access time is usually
bigger then transfer time there. Same time it requires all heads to seek

"split" is very ineffective for devices with rotating media as HDDs.
To be effective, it needs that transfer time reduction due to block

access. For modern HDDs I was able to reproduce it only with read sizes
of 2MB and above, which is almost not applicable in real life.

a468c003ef - When writing metadata to a geom provider, open the it as read-write since it
might do subsequent reads from other providers. This stopped geli (and
  probably other classes using g_metadata_store as well) from being put on top
  of gvinum raid5 volumes.

Note:
The reason it fails in the gvinum raid5 case is that gvinum will read back the
old parity stripe before calculating the new parity stripe to be written out
again.  The write will then fail because the underlying disk to be read is
opened write only.

Note that with this commit a megabyte changed from 1000000 to
1048576 and a 80G disk is now printed as being 75G in size.
This is deliberate. It's consistent with the core of geom(8).
However, the original choice for a megabyte being 1000000 was
on purpose and matches what disk vendors put on the box. The
consistency is considered more important.

Option '-B none' can by used to prevent backup. Option '-B path' can be
used to backup metadata to a different file than the default, which is
/var/backups/<prov>.eli.

The 'geli init' command also prints backup file location and gives short
procedure how to restore metadata.

The 'geli setkey' command now warns that even after passphrase change or keys
update there could be version of the master key encrypted with old
keys/passphrase in the backup file.

Add regression tests to verify that new functionality works as expected.

e770bc6bf5 First cut at GEOM based multipath. This is an active/passive{/passive...}
arrangement that has no intrinsic internal knowledge of whether devices
it is given are truly multipath devices. As such, this is a simplistic
approach, but still a useful one.

The basic approach is to (at present- this will change soon) use camcontrol
to find likely identical devices and and label the trailing sector of the
first one. This label contains both a full UUID and a name. The name is
what is presented in /dev/multipath, but the UUID is used as a true
distinguishor at g_taste time, thus making sure we don't have chaos
on a shared SAN where everyone names their data multipath as "Fred".

The first of N identical devices (and N *may* be 1!) becomes the active
path until a BIO request is failed with EIO or ENXIO. When this occurs,
the active disk is ripped away and the next in a list is picked to
(retry and) continue with.

During g_taste events new disks that meet the match criteria for existing
multipath geoms get added to the tail end of the list.

Thus, this active/passive setup actually does work for devices which
go away and come back, as do (now) mpt(4) and isp(4) SAN based disks.

There is still a lot to do to improve this- like about 5 of the 12
recommendations I've received about it,  but it's been functional enough
for a while that it deserves a broader test base.

f2aa80d883 - Allow to use -b without passphrase or with keyfiles as it will be
supported for a moment.
- Don't allow to use -i when no passphrase is given. Now if iterations is
  equal to -1 (not set), we know that we should not ask for the passphrase
  on boot.
  It still doesn't handle situation when one key is protected with
  passphrase and the other is not. There is no quick fix for this.
  The complete solution will be to make number of iterations a per-key
  value. Because this need metadata format change and is only needed for
  devices attached on boot, I'll leave it as it is for now.

f13942a746 - The geom(8) utility only uses three types of arguments: string (char *),
value (intmax_t) and boolean (int).
  Based on that provide three functions:
        - gctl_get_ascii()
        - gctl_get_int()
        - gctl_get_intmax()
- Hide gctl_get_param() function, as it is only used internally in
  subr.c.
- Allow to provide argument name as (fmt, ...).
- Assert geom(8) bugs (missing argument is a geom(8) bug).

- Clean-up and simplify the code by using new functions and assumtions
  (no more checking for missing argument).

a73148d28d Unfortunately dlerror(3) returns string, so there is no clean way to
ignore "no such file" errors only, which I wanted to do.
Because of this I ignored all other errors on dlopen(3) failure as well,
which isn't good.
Fix this situation by calling access(2) on library file first and ignore
only ENOENT error. This allows to report all the rest of dlopen(3) errors.

e68909854c - Add md_provsize field to metadata, which will help with
shared-last-sector problem.
  After this change, even if there is more than one provider with the same
  last sector, the proper one will be chosen based on its size.
  It still doesn't fix the 'c' partition problem (when da0s1 can be confused
  with da0s1c) and situation when 'a' partition starts at offset 0
  (then da0s1a can be confused with da0s1 and da0s1c). One can use '-h'
  option there, when creating device or avoid sharing last sector.
  Actually, when providers share the same last sector and their size is equal,
  they provide exactly the same data, so the name (da0s1, da0s1a, da0s1c)
  isn't important at all.
