7ce09314b2 bectl: use jail id as the default jail name for a boot environment
By default, bectl is setting the jail 'name' parameter to the boot
environment name, which causes an error when the boot environment name is
not a valid jail name. With the attached fix, when no name is supplied, the
default jail name will be the jail id - this is is the same behavior as the
jail command.

Additionally, this commit addresses two other bugs that prevented unjailing
in scenarios where the jail name does not match the boot environment name:

1. In 'bectl_locate_jail', 'mountpoint' is used to resolve the boot
  environment path, but really 'mounted' should be used. 'mountpoint' is the
  path where the zfs dataset will be mounted. 'mounted' is the path where
  the dataset is actually mounted.

2. in 'bectl_search_jail_paths', 'jail_getv' would fail after the first
  call. Which is fine, if the boot environment you're unjailing is the next
  one up. According to 'man jail_getv', it's expecting name and value
  strings. 'jail_getv' is being passed an integer for the lastjid, so amend
  that to use a string instead.

Test cases have been amended to reflect the bugs found.

9d0e9f8ef5 Try the first 256 units with nvmecontrol devlist.
The nvmecontrol code that did the devlist assumed that we had a
tightly-packed allocation of units. Since pci writing exists, this
isn't the case. Loop over the first 256 units, which is a reasonable
number of possible units.

9e5ed8593f Use VOP_ADVISE() with POSIX_FADV_DONTNEED instead of IO_DIRECT to
implement not double-caching for reads from vnode-backed md devices.
Use VOP_ADVISE() similarly instead of !IO_DIRECT unsimilarly for writes.
Add a "cache" option to mdconfig to allow changing the default of not
caching.

This depends on a recent commit to fix VOP_ADVISE().  A previous version
had optimizations for sequential i/o's (merge the i/o's and only uncache
for discontiguous i/o's and for full blocks), but optimizations and
knowledge of block boundaries belong in VOP_ADVISE().  Read-ahead should
also be handled better, by supporting it in md and discarding it in
VOP_ADVISE().

POSIX_FADV_DONTNEED is ignored by zfs, but so is IO_DIRECT.

POSIX_FADV_DONTNEED works better than IO_DIRECT if it is not ignored,
since it only discards from the buffer cache immediately, while
IO_DIRECT also discards from the page cache immediately.

IO_DIRECT was not used for writes since it was claimed to be too slow,
but most of the slowness for writes is from doing them synchronously by
default.  Non-synchronous writes still deadlock in many cases.

IO_DIRECT only has a special implementation for ffs reads with DIRECTIO
configured.  Otherwise, if it is not ignored than it uses the buffer and
page caches normally except for discarding everything after each i/o,
and then it has much the same overheads as POSIX_FADV_DONTNEED.  The
overheads for reading with ffs and DIRECTIO were similar in tests of md.

e155208020 Fsck would find, report, and offer to fix inode check-hash failures.
If requested to fix the inode check-hash it would confirm having done
it, but then fail to make the fix. The same code is used in fsdb which,
unlike fsck, would actually fix the inode check-hash.

The discrepancy occurred because fsck has two ways to fetch inodes.
The inode by number function ginode() and the streaming inode
function getnextinode() used during pass1. Fsdb uses the ginode()
function which correctly does the fix, while fsck first encounters
the bad inode check-hash in pass1 where it is using the getnextinode()
function that failed to make the correction. This patch corrects
the getnextinode() function so that fsck now correctly fixes inodes
with incorrect inode check-hashs.

8f829a5cf0 Continuing efforts to provide hardening of FFS. This change adds a
check hash to the filesystem inodes. Access attempts to files
associated with an inode with an invalid check hash will fail with
EINVAL (Invalid argument). Access is reestablished after an fsck
is run to find and validate the inodes with invalid check-hashes.
This check avoids a class of filesystem panics related to corrupted
inodes. The hash is done using crc32c.

Note this check-hash is for the inode itself and not any of its
indirect blocks. Check-hash validation may be extended to also
cover indirect block pointers, but that will be a separate (and
more costly) feature.

Check hashes are added only to UFS2 and not to UFS1 as UFS1 is
primarily used in embedded systems with small memories and low-powered
processors which need as light-weight a filesystem as possible.

fb14e73cb4 Normally when an attempt is made to mount a UFS/FFS filesystem whose
superblock has a check-hash error, an error message noting the
superblock check-hash failure is printed and the mount fails. The
administrator then runs fsck to repair the filesystem and when
successful, the filesystem can once again be mounted.

This approach fails if the filesystem in question is a root filesystem
from which you are trying to boot. Here, the loader fails when trying
to access the filesystem to get the kernel to boot. So it is necessary
to allow the loader to ignore the superblock check-hash error and make
a best effort to read the kernel. The filesystem may be suffiently
corrupted that the read attempt fails, but there is no harm in trying
since the loader makes no attempt to write to the filesystem.

Once the kernel is loaded and starts to run, it attempts to mount its
root filesystem. Once again, failure means that it breaks to its prompt
to ask where to get its root filesystem. Unless you have an alternate
root filesystem, you are stuck.

Since the root filesystem is initially mounted read-only, it is
safe to make an attempt to mount the root filesystem with the failed
superblock check-hash. Thus, when asked to mount a root filesystem
with a failed superblock check-hash, the kernel prints a warning
message that the root filesystem superblock check-hash needs repair,
but notes that it is ignoring the error and proceeding. It does
mark the filesystem as needing an fsck which prevents it from being
enabled for writing until fsck has been run on it. The net effect
is that the reboot fails to single user, but at least at that point
the administrator has the tools at hand to fix the problem.

cc624025b4 bectl(3)/libbe(3): Allow BE root to be specified
Add an undocumented -r option preceding the bectl subcommand to specify a BE
root to operate out of. This will remain undocumented for now, as some
caveats apply:

- BEs cannot be activated in the pool that doesn't contain the rootfs
- bectl create cannot work out of the box without the -e option right now,
  since it defaults to the rootfs and cross-pool cloning doesn't work like
  that (IIRC)

Plumb the BE root through to libbe(3) so that some things -can- be done to
it, e.g.

bectl -r tank/ROOT create -e default upgrade
bectl -r tank/ROOT mount upgrade /mnt

this aides in some upgrade setups where rootfs is not necessarily ZFS, and
also makes it easier/possible to regression-test bectl when combined with a
file-backed zpool.

Now an interface name can be specified for nptv6 instance instead of
ext_prefix. The module will track if_addr_ext events and when suitable
IPv6 address will be added to specified interface, it will be configured
as external prefix. When address disappears instance becomes unusable,
i.e. it doesn't match any packets.

201100c58b Initial implementation of draft-ietf-6man-ipv6only-flag.
This change defines the RA "6" (IPv6-Only) flag which routers
may advertise, kernel logic to check if all routers on a link
have the flag set and accordingly update a per-interface flag.

If all routers agree that it is an IPv6-only link, ether_output_frame(),
based on the interface flag, will filter out all ETHERTYPE_IP/ARP
frames, drop them, and return EAFNOSUPPORT to upper layers.

The change also updates ndp to show the "6" flag, ifconfig to
display the IPV6_ONLY nd6 flag if set, and rtadvd to allow
announcing the flag.

Further changes to tcpdump (contrib code) are availble and will
be upstreamed.

Tested the code (slightly earlier version) with 2 FreeBSD
IPv6 routers, a FreeBSD laptop on ethernet as well as wifi,
and with Win10 and OSX clients (which did not fall over with
the "6" flag set but not understood).

We may also want to (a) implement and RX filter, and (b) over
time enahnce user space to, say, stop dhclient from running
when the interface flag is set.  Also we might want to start
IPv6 before IPv4 in the future.

All the code is hidden under the EXPERIMENTAL option and not
compiled by default as the draft is a work-in-progress and
we cannot rely on the fact that IANA will assign the bits
as requested by the draft and hence they may change.

Dear 6man, you have running code.

f27d255c59 dumpon(8): Provide seatbelt against weak RSA keys
The premise of dumpon -k foo.pem is that dump contents will be confidential
except to anyone holding the corresponding RSA private key.

This guarantee breaks down when weak RSA keys are used.  Small RSA keys
(e.g. 512 bits) can be broken on a single personal computer in tractible
time.  Marginal RSA keys (768 bits) can be broken by EC2 and a few dollars.
Even 1024 bit keys can probably be broken by sophisticated and wealthy
attackers.

NIST SP800-57 (2016) recommends a minimum of 2048 bit RSA keys, and
estimates this provides 112 bits of security.

It would also be good to protect users from weak values of 'e' (i.e., 3) and
perhaps sanity check that their public key .pem does not accidentally
contain their private key as well.  These considerations are left as future
work.

ec888383cf Continuing efforts to provide hardening of FFS, this change adds a
check hash to the superblock. If a check hash fails when an attempt
is made to mount a filesystem, the mount fails with EINVAL (Invalid
argument). This avoids a class of filesystem panics related to
corrupted superblocks. The hash is done using crc32c.

Check hases are added only to UFS2 and not to UFS1 as UFS1 is primarily
used in embedded systems with small memories and low-powered processors
which need as light-weight a filesystem as possible.

set disable libcasper use, as with rescue builds.  Also emit a warning
as it's undesirable to build this way.

8369ba427a libbe(3)/bectl(8): Make consistent with beadm
vermaden (maintainer of beadm) points out the following inconsistencies:
- "missing command" is not printed prior to usage if the error is simply a
   missing command; this should be obvious from the context
- "bectl rename" isn't using the "don't unmount" flag (zfs rename -u), so
   the active BE can't be renamed. It doesn't make sense in our context to
   *not* use -u, so use it.

Documentation updates reflect the above and note an inconsistency with the
'destroy' command that is consistent with other parts of the base system.

A fix for libbe(3) not properly being installed to /lib is included.
SHLIBDIR should have been added when it was moved in r337995.

ff7b3f731a Extend tbrsize heuristic in pfctl(8) to provide a sensible value for
higher bandwidth interfaces.  The new value is used above 2.5 Gbps,
which is the highest standard rate that could be used prior to
r338209, so the default behavior for all existing systems should
remain the same.

The value of 128 chosen is a balance between being big enough to
reduce potential precision/quantization effects stemming from frequent
bucket refills over small time intervals and being small enough to
prevent a greedy driver from burst dequeuing more packets than it has
available hardware ring slots for whenever altq transitions from idle
to backlogged.

This keeps us from reloading the device driver when it has just been

d36967bd2b Add a new device flag: DF_ATTACHED_ONCE
This flag is set once the device has been successfully attached. When
set, it inhibits devmatch from trying to match the device. This in
turn allows kldunload to work as expected. Prior to the change, the
driver would immediately reload because devmatch had no notion that
the driver had once been attached, and therefore shouldn't participate
in further matching.

db9db0e790 bectl(8): jail: Tear down jail by default after command exits
Add a -U flag to get back the old behavior. The new behavior is a little
more friendly to the common use cases, jail the BE and execute a script.
Having the jail torn down automatically when the script is finished, or when
you exit the shell, is a little more friendly than having to remember to
`bectl ujail`.

Batch mode (-b) will continue to leave the jail up, as it's assumed the
caller has other intentions.

249cc75fd1 Extended pf(4) ioctl interface and pfctl(8) to allow bandwidths of
2^32 bps or greater to be used.  Prior to this, bandwidth parameters
would simply wrap at the 2^32 boundary.  The computations in the HFSC
scheduler and token bucket regulator have been modified to operate
correctly up to at least 100 Gbps.  No other algorithms have been
examined or modified for correct operation above 2^32 bps (some may
have existing computation resolution or overflow issues at rates below
that threshold).  pfctl(8) will now limit non-HFSC bandwidth
parameters to 2^32 - 1 before passing them to the kernel.

The extensions to the pf(4) ioctl interface have been made in a
backwards-compatible way by versioning affected data structures,
supporting all versions in the kernel, and implementing macros that
will cause existing code that consumes that interface to use version 0
without source modifications.  If version 0 consumers of the interface
are used against a new kernel that has had bandwidth parameters of
2^32 or greater configured by updated tools, such bandwidth parameters
will be reported as 2^32 - 1 bps by those old consumers.

All in-tree consumers of the pf(4) interface have been updated.  To
update out-of-tree consumers to the latest version of the interface,
define PFIOC_USE_LATEST ahead of any includes and use the code of
pfctl(8) as a guide for the ioctls of interest.

9544e6dcf1 Make NVMe compatible with the original API
The original NVMe API used bit-fields to represent fields in data
structures defined by the specification (e.g. the op-code in the command
data structure). The implementation targeted x86_64 processors and
defined the bit fields for little endian dwords (i.e. 32 bits).

This approach does not work as-is for big endian architectures and was
changed to use a combination of bit shifts and masks to support PowerPC.
Unfortunately, this changed the NVMe API and forces #ifdef's based on
the OS revision level in user space code.

This change reverts to something that looks like the original API, but
it uses bytes instead of bit-fields inside the packed command structure.
As a bonus, this works as-is for both big and little endian CPU
architectures.
