037331ddbd When read requests are sent from a filesystem running above g_journal,
the g_journal level needs to check whether it is holding a newer
copy of the block than that which exists on the disk. If so, it
needs to return its copy. If not, it should pass the request down
to the disk to fulfill. It currently considers six queues:

0) delayed queue,
1) unsent (current queue),
2) in-flight to the journal (flush queue),
3) active journal (active queue),
4) inactive journal (inactive queue), and
5) inflight to the disk (copy queue).

Checking on two of these queues is unnecessary:

0) The delayed requests should not be used for reads because they
   have not yet been entered into the journal, so their value should
   reflect the disk contents, not the future contents that are not
   yet committed.

2) Because all the bio's in the flush queue are also found on the
   active queue, there is no need to inspect the flush queue for
   reads since they will be found when searching the active queue.

d3517d306c Expose API to allow disks to ask for alias names in devfs.
Implement disk_add_alias to allow aliases to be added to disks. All
disk have a primary name (say "foo") can also have secondary names
(say "bar") such that all instances of "foo" also have a "bar"
alias. So if you have foo0, foo0p1, foo1, foo1s1 and foo1s1a nodes
created by the foo driver and gpart, device nodes bar0, bar0p1, bar1,
bar1s1 and bar1s1a will appear as symlinks back to the original nodes.
This generalizes to multiple aliases. However, since the unit number
follows the primary name, multiple device drivers can't create the
same aliases unless those drives coorinate the unit number space (eg
you couldn't add an alias 'disk' to both 'da' and 'ada' because it's
possible to have da0 and ada0, because 'disk0' is ambiguous).

5d7d13290a Add alias support to gpart.
When we're creating new providers for each of the partitions, add
aliases to the geom before we create the provider so when geom_dev
tastes the provider, the aliases are in place so the proper /dev
entries are created. So foo5p6 gets created as an alias for bar5p6
when foo is an alias for bar in the geom we're partitioning with
g_part. This also copies aliases from the container geom (eg disk) to
the label geom (the disk with GPT partitioning) so that aliases nest
properly.

6c6118b390 gjournal is broken in handling its flush_queue. If we have 10 bio's
in the flush_queue:
         1 2 3 4 5 6 7 8 9 10
and another 10 bio's go into the flush queue after only the first five
bio's are removed from the flush queue, the queue should look like:
         6 7 8 9 10 11 12 13 14 15 16 17 18 19 20,
but because of the bug we end up with
         6 11 12 13 14  15 16 17 18 19 20 7 8 9 10.
So the sequence of the bio's is damaged in the flush queue (and
therefore in the journal on disk !). This error can be triggered by
ffs_snapshot() when a block is read with readblock() and gjournal finds
this block in the broken flush queue before it goes to the correct
active queue.

The fix is to place all new blocks at the end of the queue.

683590b642 sysctl kern.geom.journal.cache.limit shows negative value for FreeBSD/amd64
system having over 4GB RAM. That's due to:

   half of vm.kmem_size by default for amd64);
2) sysctl handler g_journal_cache_limit_sysctl() using u_int instead of u_long.

The fix is to replace u_int with u_long for the kern.geom.journal.cache.limit

ec5c0e5be9 Implement boot-time encryption key passing (keybuf)
This patch adds a general mechanism for providing encryption keys to the
kernel from the boot loader. This is intended to enable GELI support at
boot time, providing a better mechanism for passing keys to the kernel
than environment variables. It is designed to be extensible to other
applications, and can easily handle multiple encrypted volumes with
different keys.

This mechanism is currently used by the pending GELI EFI work.
Additionally, this mechanism can potentially be used to interface with
GRUB, opening up options for coreboot+GRUB configurations with completely
encrypted disks.

Another benefit over the existing system is that it does not require
re-deriving the user key from the password at each boot stage.

Most of this patch was written by Eric McCorkle. It was extended by
Allan Jude with a number of minor enhancements and extending the keybuf
feature into boot2.

GELI user keys are now derived once, in boot2, then passed to the loader,
which reuses the key, then passes it to the kernel, where the GELI module
destroys the keybuf after decrypting the volumes.

85c15ab853 improve PBKDF2 performance
The PBKDF2 in sys/geom/eli/pkcs5v2.c is around half the speed it could be

GELI's PBKDF2 uses a simple benchmark to determine a number of iterations
that will takes approximately 2 seconds. The security provided is actually
half what is expected, because an attacker could use the optimized
algorithm to brute force the key in half the expected time.

With this change, all newly generated GELI keys will be approximately 2x
as strong. Previously generated keys will talk half as long to calculate,
resulting in faster mounting of encrypted volumes. Users may choose to
rekey, to generate a new key with the larger default number of iterations
using the geli(8) setkey command.

Security of existing data is not compromised, as ~1 second per brute force
attempt is still a very high threshold.

480f31c214 Add support for encrypted kernel crash dumps.
Changes include modifications in kernel crash dump routines, dumpon(8) and
savecore(8). A new tool called decryptcore(8) was added.

A new DIOCSKERNELDUMP I/O control was added to send a kernel crash dump
configuration in the diocskerneldump_arg structure to the kernel.
The old DIOCSKERNELDUMP I/O control was renamed to DIOCSKERNELDUMP_FREEBSD11 for
backward ABI compatibility.

dumpon(8) generates an one-time random symmetric key and encrypts it using
an RSA public key in capability mode. Currently only AES-256-CBC is supported
but EKCD was designed to implement support for other algorithms in the future.
The public key is chosen using the -k flag. The dumpon rc(8) script can do this
automatically during startup using the dumppubkey rc.conf(5) variable.  Once the
keys are calculated dumpon sends them to the kernel via DIOCSKERNELDUMP I/O
control.

When the kernel receives the DIOCSKERNELDUMP I/O control it generates a random
IV and sets up the key schedule for the specified algorithm. Each time the
kernel tries to write a crash dump to the dump device, the IV is replaced by
a SHA-256 hash of the previous value. This is intended to make a possible
differential cryptanalysis harder since it is possible to write multiple crash
dumps without reboot by repeating the following commands:
# sysctl debug.kdb.enter=1
db> call doadump(0)
db> continue
# savecore

A kernel dump key consists of an algorithm identifier, an IV and an encrypted
symmetric key. The kernel dump key size is included in a kernel dump header.
The size is an unsigned 32-bit integer and it is aligned to a block size.
The header structure has 512 bytes to match the block size so it was required to
make a panic string 4 bytes shorter to add a new field to the header structure.
If the kernel dump key size in the header is nonzero it is assumed that the
kernel dump key is placed after the first header on the dump device and the core
dump is encrypted.

Separate functions were implemented to write the kernel dump header and the
kernel dump key as they need to be unencrypted. The dump_write function encrypts
data if the kernel was compiled with the EKCD option. Encrypted kernel textdumps
are not supported due to the way they are constructed which makes it impossible
to use the CBC mode for encryption. It should be also noted that textdumps don't
contain sensitive data by design as a user decides what information should be
dumped.

savecore(8) writes the kernel dump key to a key.# file if its size in the header
is nonzero. # is the number of the current core dump.

decryptcore(8) decrypts the core dump using a private RSA key and the kernel
dump key. This is performed by a child process in capability mode.
If the decryption was not successful the parent process removes a partially
decrypted core dump.

Description on how to encrypt crash dumps was added to the decryptcore(8),
dumpon(8), rc.conf(5) and savecore(8) manual pages.

EKCD was tested on amd64 using bhyve and i386, mipsel and sparc64 using QEMU.
The feature still has to be tested on arm and arm64 as it wasn't possible to run
FreeBSD due to the problems with QEMU emulation and lack of hardware.

b6fe583c55 Add gmirror create subcommand, alike to gstripe, gconcat, etc.
It is quite specific mode of operation without storing on-disk metadata.
It can be useful in some cases in combination with some external control
tools handling mirror creation and disks hot-plug.
