As mentioned in the commit message of r289041, nl_langinfo(ABMON_*) only

DIRDEPS_BUILD: Fix 'make bootstrap-tools' not using the proper tblgen binaries.
This was an incomplete item from r291561. The host {clang,llvm}-tblgen

- DIRDEPS_BUILD: Fix crunchgen builds losing their library dependencies
on a nop-rebuild.
- META_MODE: Fix not rebuilding various crunch.mk targets if their .meta
files warrant a rebuild. They were lacking .meta files previously.
This adds .NOMETA to the crunch objects being used since they are
already built. Bmake was forcing a rebuild on them since their
.meta files were not in the expected place; there is no reason to
rebuild them.
fgetwc(3) may set both __SEOF and __SERR at once (in case of incomplete

__SERR clearing/restoring.
The log message for the previous commit didn't mention the most the
important detail that sc_cngetc() now opens and closes the keyboard
on every call again. This was moved from sc_cngetc() to scn_cngrab/
ungrab() in r228644, but the change wasn't quite complete. After
fixes for nesting in kbdd_poll() in ukbd and kbdmux, these opens
and closes should have no significant effect if done while grabbed.
They fix unusual cases when cngetc() is called while not grabbed.
This commit is the main fix for screen locking in sc_cnputc():
detect deadlock or likely-deadlock and handle it by buffering the
output atomically and printing it later if the deadlock condition
clears (and sc_cnputc() is called).
The most common deadlock is when the screen lock is held by ourself.
Then it would be safe to acquire the lock recursively if the console
driver is calling printf() in a safe context, but we don't know when
that is. It is not safe to ignore the lock even in kdb or panic mode.
But ignore it in panic mode. The only other known case of deadlock
is when another thread holds the lock but is running on a stopped CPU.
Detect that case approximately by using trylock and retrying for 1000
usec. On a 4 GHz CPU, 100 usec is almost long enough -- screen switches
take slightly longer than that. Not retrying at all is good enough
except for stress tests, and planned future versions will extend the
timeout so that the stress tests work better.
To see the behaviour when deadlock is detected, single step through
sctty_outwakeup() (or sc_puts() to start with deadlock). Another
(serial) console is needed to the buffered-only output, but the
keyboard works in this context to continue or step out of the
deadlocked region. The buffer is not large enough to hold all the
output for this.

Pull in r277331 from upstream llvm trunk (by Diana Picus):
[AArch64] Return the correct size for TLSDESC_CALLSEQ
The branch relaxation pass is computing the wrong offsets because it assumes
TLSDESC_CALLSEQ eats up 4 bytes, when in fact it is lowered to an instruction
sequence taking up 16 bytes. This can become a problem in huge files with lots
of TLS accesses, as it may slowly move branch targets out of the range computed
by the branch relaxation pass.
FAST_DEPEND/META_MODE: Fix several issues with SRCS containing '/'.
- For FAST_DEPEND, properly apply the -M flags when compiling by
enduring that the condition also has the s,/,_,g filter applied to it
first.
- For FAST_DEPEND, properly read from the filtered filename.
- For META_MODE, it needs to read from a full-pathed and s,/,_,g replaced
filename based on bmake's meta_name() function which names the .meta
file for SRCS with '/' in them.
This support has not been extended to the kernel build yet but may be in the
future.

If you create a zfs child folder, zfs send returns an error when a recursive
incremental send is done between two snapshots made prior to the folder
creation.
The problem can be reproduced with the following steps.
root@zfs:/# zfs create pool/test
root@zfs:/# zfs snapshot pool/test@snap1
root@zfs:/# zfs snapshot pool/test@snap2
root@zfs:/# zfs create pool/test/child
root@zfs:/# zfs send -R -I pool/test@snap1 pool/test@snap2 > /dev/null
WARNING: could not send pool/test/child@snap2: does not exist
WARNING: could not send pool/test/child@snap2: does not exist
root@zfs:/# echo $?

root@zfs:/# zfs snapshot -r pool/test@snap3
root@zfs:/# zfs send -R -I pool/test@snap1 pool/test@snap3 > /dev/null
root@zfs:/# echo $?
0
root@zfs:/# zfs send -R -I pool/test@snap2 pool/test@snap3 > /dev/null
root@zfs:/# echo $?
0
Since pool/test/child was created after snap2, zfs send should not expect snap2
to be in pool/test/child when doing a recursive send. It should examine the
compare the creation time of the snapshot and each child folder to decide if
the folder will be sent. The next incremental send between snap2 and snap3
would properly create the child folder and snap3 which first appears in the
child folder.
The problem is identical if '-i' is used instead of '-I'.

Currently zfsdev_ioctl, when confronted by a request with the FKIOCTL flag set,
skips all processing of secpolicy functions. This means that ZFS is not doing
any kind of verification of the credentials or access rights of the caller and
assuming that (as it is an in-kernel client) all such checks have already been
done.
This turns out to be quite a dangerous assumption, especially with respect to
sdev. In general I don't think it's particularly reasonable to offload this
enforcement of access rights onto other kernel subsystems when ZFS has some
particular local semantics in this area (delegated datasets etc) and does not
provide any kind of API to allow other subsystems to avoid code duplication
when doing it. ZFS should apply its normal access policy to requests from
within the kernel, and callers should take care to give it the correct
credentials and call it from the correct context in order to get the results
they need.
You can observe the currently unfortunate consequences of this bug in any non-
global zone that has access to /dev/zvol or any subset of it via sdev profiles.
In particular, a zone used to contain a KVM or similar which has a single zvol
passed through to it using a <device match= block in its zone XML.
Even though sdev makes something of an attempt to control for whether the
caller should have access to nodes in /dev/zvol, it doesn't do this correctly,
or really at all in the lookup call path. So, if we have a zone that's been
given access to any part of /dev/zvol, it can simply look up the full path to
any other zvol on the entire system, and the node will appear and be able to be
used.

ZFS does not do a config_sync after removing an aux (spare, log, or cache)
device. AFAICT this isn't being done because it is slow and was deemed
unnecessary. However, it should be such a rare operation that speed doesn't
matter, and not doing it results in two problems:
1) It is theoretically possible to remove an aux device from one pool and
attach it to another, then lose power. When power is restored, both pools woul
d
think that they own the aux device.
2) Removal of the aux device doesn't send any useful sysevents to userland.
