af876563d1 lualoader: Add reload-conf loader command
This command will trigger a reload of the configuration from disk. This is
useful if you've changed currdev from recovery media to local disk as much
as I have over the past ~2 hours and are tired of the extra keystrokes.

This is really just a glorified shortcut, but reload-conf is likely easier
to remember for other people and does save some keystrokes when reloading
the configuration. It is also resilient to the underlying config method
changing interface, but this is unlikely to happen.

1c56203bcf powerpc64/powernv: Add opal NVRAM driver for PowerNV systems
Add a very basic NVRAM driver for OPAL which can be used by the IBM
powerpc-utils nvram utility, not to be confused with the base nvram utility,
which only operates on powermac_nvram.

The IBM utility handles all partitions itself, treating the nvram device as
a plain store.

An alternative would be to manage partitions in the kernel, and augment the
base nvram utility to deal with different backing stores, but that
complicates the driver significantly.  Instead, present the same interface
IBM's utlity expects, and we get the usage for free.

ee41e38d42 Add support for Intel Stratix 10 platform.
Intel Stratix 10 SoC includes a quad-core arm64 cluster and FPGA fabric.

This adds support for reconfiguring FPGA.

Accessing FPGA core of this SoC require the level of privilege EL3,
while kernel runs in EL1 (lower) level of privilege.

This provides an Intel service layer interface that uses SMCCC to pass
queries to the secure-monitor (EL3).

ce3ba63f67 vfs: release usecount using fetchadd
1. If we release the last usecount we take ownership of the hold count, which
means the vnode will remain allocated until we vdrop it.
2. If someone else vrefs they will find no usecount and will proceed to add
their own hold count.
3. No code has a problem with v_usecount transitioning to 0 without the
interlock

These facts combined mean we can fetchadd instead of having a cmpset loop.

8156570000 Update libedit to a snapshot from 2019-09-10
This version bring many fixes regarding unicode support
It also adds proper support for filename completion (we do not need our custom
patches anymore)
Improves the libreadline compatibility

Note that the same work was done by Yuichiro Naito in
https://reviews.freebsd.org/D21196 the main difference is in this case we have
reimported libedit in contrib to fix a long standing mess in the previous merges
which prevented a proper update workflow. (discussed long ago with pfg@)

The only difference with upstream libedit is we have added a compatibility shim
for the _elf_fn_sh_complete function which we previously added to support quoting
in filename completion and is not needed anymore.
This was added to continue supported old /bin/sh binaries and not break backward
compatibility (as discussed with jilles@)

As I like to forget: static kenv var formatting is actually such that an

436c46875d kenv: assert that an empty static buffer passed in is "empty"
Garbage in the passed-in buffer can cause problems if any attempts to read
the kenv are inadvertently made between init_static_kenv and the first
kern_setenv -- assuming there is one.

This is cheap and easy, so do it. This also helps rule out some class of
bugs as one tries to debug; tunables fetch from the static environment up
until SI_SUB_KMEM + 1, and many of these buffers are global ~4k buffers that
rely on BSS clearing while others just grab a page of free memory and use it
(e.g. xen).

aaa3852435 buf: Add B_INVALONERR flag to discard data
Setting the B_INVALONERR flag before a synchronous write causes the buf
cache to forcibly invalidate contents if the write fails (BIO_ERROR).

This is intended to be used to allow layers above the buffer cache to make
more informed decisions about when discarding dirty buffers without
successful write is acceptable.

As a proof of concept, use in msdosfs to handle failures to mark the on-disk
'dirty' bit during rw mount or ro->rw update.

Extending this to other filesystems is left as future work.

8d910a4282 getsockopt.2: clarify that SO_TIMESTAMP is not 100% reliable
When SO_TIMESTAMP is set, the kernel will attempt to attach a timestamp as
ancillary data to each IP datagram that is received on the socket. However,
it may fail, for example due to insufficient memory. In that case the
packet will still be received but not timestamp will be attached.

b17fb99228 ping: Verify whether a datagram timestamp was actually received.
ping(8) uses SO_TIMESTAMP, which attaches a timestamp to each IP datagram at
the time it's received by the kernel.  Except that occasionally it doesn't.
Add a check to see whether such a timestamp was actually set before trying
to read it.  This fixes segfaults that can happen when the kernel doesn't
attach a timestamp.

The bug has always existed, but prior to r351461 it manifested as an
implausible round-trip-time, not a segfault.

d2e6258258 Avoid unneeded call to arc4random() in syncache_add()
Don't call arc4random() unconditionally to initialize sc_iss, and
then when syncookies are enabled, just overwrite it with the
return value from from syncookie_generate(). Instead, only call
arc4random() to initialize sc_iss when syncookies are not
enabled.

Note that on a system under a syn flood attack, arc4random()
becomes quite expensive, and the chacha_poly crypto that it calls
is one of the more expensive things happening on the
system. Removing this unneeded arc4random() call reduces CPU from
about 40% to about 35% in my test scenario (Broadwell Xeon, 6Mpps
syn flood attack).
