GEOM is supposed to be topology-agnostic, but the GPT and BSD partition code
has arbitrary restrictions on nesting that are annoying in cases such as
running VMs on raw partitions (since the VM's partitioning scheme is not
visible to the host).
This patch adds sysctls to disable the restrictions except in the case of
BSD label (and similar) partitions with offset 0 (where we need to avoid
recursively recognizing the label).

- Triple DES has been formally deprecated in Kerberos (RFC 8429)
and is soon to be deprecated in IPsec (RFC 8221).
- Blowfish is deprecated. FreeBSD doesn't support its successor
(Twofish).
- MD5 is generally considered a weak digest that has known attacks.
geli refuses to create new volumes using these algorithms via 'geli
init'. It also warns when attaching to existing volumes or creating
temporary volumes via 'geli onetime' . The plan is to fully remove
support for these algorithms in FreeBSD 13.
Note that none of these algorithms have ever been the default
algorithm used by geli(8). Users would have had to explicitly select
these algorithms when creating volumes in the past.

provider grows, GELI will expand automatically and will move the metadata
to the new location of the last sector.
This functionality is turned on by default. It can be turned off with the
-R flag, but it is not recommended - if the underlying provider grows and
automatic expansion is turned off, it won't be possible to attach this
provider again, as the metadata is no longer located in the last sector.
If the automatic expansion is turned off and the underlying provider grows,
GELI will only log a message with the previous size of the provider, so
recovery can be easier.

that don't support serial numbers, and allows boot0cfg to set the serial

Apply some fixes post rS336659, which allowed multiple provders to be
initialized in a single command.
- Fix issue where second and subsequent providers would fail init.
This was due to the metadata struct being zeroed after the first
provider init was completed, despite containing common data required
for subsequent providers.
- Fix issue where -B "none" would still result in the metadata being
backed-up if multiple providers had been specified. This was due to
the backupfile of "none" being incorrectly made unique for each
provider by appending "-<prov>".

Unique salt will be randomly generated for each provider to ensure the
Master Key for each is unique.
This change follows on from r335673 and r336602, which allowed multiple
providers to be attached in a single command.

Now that multiple providers can be attached at once, exit codes and

Allow attaching of multiple geli providers at once if they use same
passphrase and keyfiles.
This is helpful when the providers being attached are not used for boot,
and therefore the existing code to first try the cached password when
tasting the providers during boot does not apply.
Multiple providers with the same passphrase and keyfiles can be attached
at the same time during system start-up by adding the following to
rc.conf:
geli_groups="storage backup"
geli_storage_flags="-k /etc/geli/storage.keys"
geli_storage_devices="ada0 ada1"
geli_backup_flags="-j /etc/geli/backup.passfile -k /etc/geli/backup.keys"

Rather then combining hardlink creation for the geom(8) binary with
shared library build, move libraries to src/lib/geom so they are
built and installed normally. Create a common Makefile.classes
which is included by both lib/geom/Makefile and sbin/geom/Makefile
so the symlink and libraries stay in sync.
The relocation of libraries allows libraries to be build for 32-bit
compat. This also reduces the number of non-standard builds in
the system.
This commit is not sufficent to run a 32-bit /sbin/geom on a 64-bit
system out of the box as it will look in the wrong place for libraries
unless GEOM_LIBRARY_PATH is set appropriatly in the environment.
