Loader is still relied upon at the beginning of libbe to specify the be
root, but we can derive from that the primary zpool and any vdevs that we
need to set nextboot bits on.
This lets me successfully `bectl activate -t test`, but UEFI loader doesn't
quite yet understand so it's effectively defunct.
- Support passing arbitrary jail arguments via -o
- Split the related (and rewritten since the GSoC) jail bits out into a new
bectl_jail.c file, to reduce clutter in bectl.c
- Don't use RFC 1918 IP space [0]; we'll instead set no default IPv4 and let
the user pass in any address options they wish via -o

be_get_dataset_snapshots has been added to libbe(3), effectively returning
the same information as be_get_bootenv_props but for snapshots of the given
dataset. The assumption is that one will have the BE dataset name before
wanting to grab snapshots.
This also accomplishes the following:
- Proxy through zfs_nicenum as be_nicenum, because it looks better than
humanize_number and would presumably be useful to other libbe consumers.
- Rename be_get_snapshot_props to be_get_dataset_props, make it more useful
-H is for a scripted format, where all fields are tab-delimited and the
headers go away. We accomplish this by splitting out pad printing to a
separate function that'll take into account whether we're supposed to be
scripted or not.
This has the nice side effect of maintaining positive column sizes again.
While it could be preferred to do this at insert in libbe(3), there's no
convenient way to insert at the head of an nvlist. Instead, we'll make two
passes over- once to print anything active either now or at nextboot, and
another to print everything else.
This doesn't actually impact performance in a significant way here, so we'll
worry about further optimizations if the need actually arises.
bectl list -a should show the boot environment, its relevant dataset, and
the snapshot it was created from. The header also changes to indicate the
rough order in which these things will show.
While here, start doing a little bit of spring cleaning and splitting
different bits out.
The jail is created with allow.mount, allow.mount.devfs, and
enforce_statfs=1. Upon creation, we immediately attach, chdir to "/", and
drop the user into a shell inside the jail.
The default IP for this is arbitrarily 10.20.30.40.
The given parameter may either be a jid, jail name, or a BE name. In all
cases, the parameter will be resolved to a jid and bectl(8) will
sanity-check that there's actually a BE mounted at the requested jail root
before invoking jail_remove(2).
At a bare minimum, this function will return 0 if a BE is mounted at the
given path or non-zero otherwise. If the optional 'details' nvlist is
supplied, it is filled with an nvpair containing just the information about
the BE mounted at the path. This nvpair is structured just as it is for
be_get_bootenv_props, except limited to just the single mount point.
Based on the idea that we shouldn't have all-new library and utility going
into base that need WARNS=1...
- Decent amount of constification
- Lots of parentheses
- Minor other nits
For the moment, this is a primitive nvlist dump of what we get back from
be_get_bootenv_props as a proof-of-concept and to make sure that we're
getting back the kind of information we want to see from list.
This makes us more resilient to a rename of the bootfs, but still wouldn't
withstand pool renames or guid renames. More importantly, this allows `bectl
create <foo>` work out of the box to create a boot environment based on the
currently booted one.
- Rename 'active' to 'rootfs', which is used in other places to describe the
currently booted (or about to be booted) BE.
- Add 'bootfs', which indicates the next boot environment to be booted. This
is pulled from the BOOTFS zpool property.
- Go ahead and keep an open handle to the active zpool. We might need to
enumerate datasets, get properties, and set properties (e.g. bootfs)
throughout other libbe bits, and a single handle isn't overly expensive.
Perhaps using libbe.a from "${DESTDIR}${LIBDIR}" might have been the
prevailing technique at one point, but nowadays it appears to be to
preferred to spell this as "${OBJTOP}/lib" -- make it so.

The remquo*() and remainder*() functions should now give bitwise identical
results across arches and implementations, and bitwise consistent results
(with lower precisions having truncated mantissas) across precisions. x86
already had consistency across amd64 and i386 and precisions by using the
i387 consistently and normally not using the C versions. Inconsistencies
for C reqmquol() were first detected on sparc64.

remainder*(x, y) and remquo*(x, y, quo) were broken for y = 0 by changing
multiplication by y to addition of y. (When y is 0, the result should be
NaN but became 1 for finite x.)
Use a new macro nan_mix_op() to give more control over the mixing, and
expand comments.
Recent re-testing missed finding this bug since I only tested the macro
version on amd64 and i386 and these arches don't use the C versions (they
use either asm versions or builtins).

jedec_dimm(4) is a superset of the functionality of jedec_ts(4). Mark
jedec_ts(4) as removed in FreeBSD 12, and include a pointer to the migration
instructions in the jedec_dimm(4) manpage, in both the jedec_ts(4) code and
the jedec_ts(4) manpage. Add a note to the jedec_dimm(4) manpage about the
fact that it is a superset of jedec_ts(4).
This change will be MFCed to stable/11 and stable/10; the followup change
to actually remove jedec_ts(4) from -HEAD will not.

If we are booting in a conforming UEFI Boot Manager Environment, then
use the BootCurrent variable to find the BootXXXX we're using. Once we
find that, then if it contains more than one EFI_DEVICE_PATH in its
what to boot section, try to use the last one as the kernel to
load. This will also set the default root partition as well. If
there's only one path, or if there's an error along the way, assume
that nothing specific was specified and revert to the old
algorithm. If something was specified, but not found, then fail the
boot. Otherwise you that, specific thing. On FreeBSD, this can be set
using efibootmgr -l <loader> -k <kernel>. We try a few variations of
kernel to cope with the fact that UEFI comes from a DOS world where
paths might be upper case and/or contain back-slashes.
Note: In an ideal world, we'd work out where we are in chain loading
by looking at the passed-in image handle and doing name
matching. However, that's unreliable since at least boot1.efi booted
images don't have that, hence the assumption that loader.efi needs to
load the last thing on the list, if possible.
The reason we fail for something specific is so that we can fully
participate in the UEFI Boot Manager Protocol and fail over to the
next item in the list of BootOrder choices when something goes wrong
at this stage.

Lookup a block device by it's device path. We use a 'loose' lookup
whereby we scan forward to the first Media Path portion of the device
path, then look at all our handles for one whose first Media Path
matches. This will also work if the device path pointed to has a
following file path (or paths) as that's ignored. It assumes that
there's only one media path node that describes the entire device,
which is true as of the latest UEFI spec (2.7 Errata A) as far as I've
been able to determine.
