bdd57cbb1b nfsd: Add checks for layout errors in LayoutReturn
For a LayoutReturn when using the Flexible File Layout,
error reports may be provided in the request.
Sanity check the size of these error reports and
check that they exist before calling nfsrv_flexlayouterr().

ae92ace05f Per-thread stack canary on arm64
With the update to llvm 13 we are able to tell the compiler it can find
the SSP canary relative to the register that holds the userspace stack
pointer. As this is unused in most of the kernel it can be used here
to point to a per-thread SSP canary.

As the kernel could be built with an old toolchain, e.g. when upgrading
from 13, add a warning that the options was enabled but the compiler
doesn't support it to both the build and kernel boot.

ff1e858180 twsi: support more message combinations in transfers
Most prominently, add support for a transfer where a write with no-stop
flag is followed by a write with no-start flag.  Logically, it's a
single larger write, but consumers may want to split it like that
because one part can be a register ID and the other part can be data to
be written to (or starting at) that register.

Such a transfer can be created by i2c tool and iic(4) driver, e.g., for
an EEPROM write at specific offset:
    i2c -m tr -a 0x50 -d w -w 16 -o 0 -c 8 -v < /dev/random

This should be fixed by new code that handles the end of data transfer
for both reads and writes.  It handles two existing conditions and one
new.  Namely:
- the last message has been completed -- end of transfer;
- a message has been completed and the next one requires the start
  condition;
- a message has been completed and the next one should be sent without
  the start condition.

In the last case we simply switch to the next message and start sending
its data.  Reads without the start condition are not supported yet,
though.  That's because we NACK the last byte of the previous message,
so the device stops sending data.  To fix this we will need to add a
look-ahead at the next message when handling the penultimate byte of the
current one.

This change also fixed a bug where msg_idx was not incremented after a
read message.  Apparently, typically a read message is a last message in
a transfer, so the bug did not cause much trouble.

04622a7f21 twsi: move handling of TWSI_CONTROL_ACK into the state machine
Previously the code set TWSI_CONTROL_ACK in twsi_transfer() based on
whether the first message had a length of one.  That was done regardless
of whether the message was a read or write and what kind of messages
followed it.
Now the bit is set or cleared while handling TWSI_STATUS_ADDR_R_ACK
state transition based on the current (read) message.

The old code did not correctly work in a scenario where a single byte
was read from an EEPROM device with two byte addressing.
For example:
    i2c -m tr -a 0x50 -d r -w 16 -o 0 -c 1 -v
The reason is that the first message (a write) has two bytes, so
TWSI_CONTROL_ACK was set and never cleared.
Since the controller did not send NACK the EEPROM sent more data resulting
in a buffer overrun.

While working on TWSI_STATUS_ADDR_R_ACK I also added support for
the zero-length read access and then I did the same for zero-length write
access.
While rare, those types of I2C transactions are completely valid and are
used by some devices.

a4fe892208 twsi: unify error handling, explicitly handle more conditions
twsi_error() is a new function that stops the current transfer and sets
up softc when an error condition is detected.
TWSI_STATUS_DATA_WR_NACK, TWSI_STATUS_BUS_ERROR and
TWSI_STATUS_ARBITRATION_LOST are now handled explicitly rather than
via the catch-all unknown status.

Also, twsi_intr() now calls wakeup() in a single place when the
transfer is finished.

a2793d6182 twsi: compile in support for debug messages, disabled by default
Debug messages can now be enabled per driver instance via a new sysctl.
Also, debug messages in TWSI_READ and TWSI_WRITE require debug level
greater than 1 as they are mostly redundant because callers of those
functions already log most interesting results.

NB: the twsi drivers call their device iichb, so the new sysctl will
appear under dev.iichb.N.

df90aeac24 Fix build with -DNO_ROOT
The inclusion of 0a0f748641 broke the build with the -DNO_ROOT option.
Specifically, that commit adds some relative paths (with `..`) to METALOG
that make other tools using that log, fail afterwards (tar, makefs...).

It's been argued[1] if this is really something mtree(8) should handle more
graciously. In the meantime, fix the breakage but changing the order in which
the links are created: first in the parent directory, then in the
architecture-specific one.

We keep the architecture-specific directories an the links to the parent
directories. This is something that we might want to change in the future.

This commit is based on a concept patch by avg@.

e29711da23 etc/defaults/rc.conf: Add -i flag to rtsol/rtsold
This disables the random (between zero and one seconds) delay before
rtsol and rtsold send a a Router Solicitation packet.  This delay is
specified as a SHOULD by RFC 4861 for avoidance of network congestion,
but network speeds have increased enough in the 25 years since this
first appeared (in RFC 1970) that it seems unnecessary as a default
at this point.

This speeds up the FreeBSD boot process by an average of 500 ms.
