bottom of the file, where it is in most imx5/6 drivers. Switch from an RD2
macro using bus_space_read_2() to an inline function using bus_read_2();
likewise for WR2. Use RESOURCE_SPEC_END to end the resource_spec list.
Net effect should be no functional changes.
The header passed to these probes has some fields converted to host
order by tcp_fields_to_host(), so the tcpinfo_t translator doesn't do
what we want.

Sometimes 32 bit and 64 bit ioctls are represented by the same number.
It causes unnecessary switch to 32 bit commpatible mode.
This patch prevents switching when we are dealing with 64 bit executable.
It fixes issue mentioned here

routine to write out the cylinder groups rather than recreating the
calculation of the cylinder-group check hash in fsck_ffs.
No functional change intended.
FreeBSD and industry has been inconsistent in the use of UEFI and EFI.
They are essentially just different versions of the same specification
and are often used interchangeably. Make it easier for users to find
information by making efi(8) an alias for uefi(8).

This patch is cosmetic. It checks if allocation of ifnet structure failed.
It's better to have this check rather than assume positive scenario.

- EFI support appeared in 5.0 for ia64
- arm64 UEFI support added in 11.0
The AUTHORS section included the folks responsible for the bulk of the
work to bring UEFI support to amd64, but missed those who did the
original work on ia64, the initial port to i386, the ports to arm64 and
arm, and have generally maintained and improved general UEFI support
since then. It's unwieldly to include everyone and would quickly become
outdated again anyhow, so just remove the AUTHORS section.

Properly honor the lack of the CRD_F_IV_PRESENT flag in the GCM
software fallback case for encryption requests.

In particular, this avoids edge cases where a generated IV might be
written into the output buffer even though the request is failed with
an error.

- Extend ccr_gcm_soft() to handle requests with a non-empty payload.
While here, switch to allocating the GMAC context instead of placing
it on the stack since it is over 1KB in size.
- Allow ccr_gcm() to return a special error value (EMSGSIZE) which
triggers a fallback to ccr_gcm_soft(). Move the existing empty
payload check into ccr_gcm() and change a few other cases
(e.g. large AAD) to fallback to software via EMSGSIZE as well.
- Add a new 'sw_fallback' stat to count the number of requests
processed via the software fallback.

This works around an issue in the T6 that can result in DMA engine

Most crypto requests will not trigger this condition, but a request
with a highly-fragmented data buffer (and a resulting "large" S/G
list) could trigger it.
Sponsored by: Chelsio Communications
The T6 can hang when processing certain AEAD requests if the request
sets a flag asking the crypto engine to discard the input IV and AAD
rather than copying them into the output buffer. The existing driver
always discards the IV and AAD as we do not need it. As a workaround,
allocate a single "dummy" buffer when the ccr driver attaches and
change all AEAD requests to write the IV and AAD to this scratch
buffer. The contents of the scratch buffer are never used (similar to
"bogus_page"), and it is ok for multiple in-flight requests to share
this dummy buffer.

The T6 crypto engine's control messages only support a total AAD
length (including the prefixed IV) of 511 bytes. Reject requests with
large AAD rather than returning incorrect results.
Sponsored by: Chelsio Communications
Combined authentication-encryption and GCM requests already stored the
IV in the immediate explicitly. This extends this behavior to block
cipher requests to work around a firmware bug. While here, simplify
the AEAD and GCM handlers to not include always-true conditions.

Fix a vulnerability in IPsec-IPv6-AH, that allows an attacker to remotely
crash the kernel with a single packet.
In this loop we need to increment 'ad' by two, because the length field
of the option header does not count the size of the option header itself.
If the length is zero, then 'count' is incremented by zero, and there's
an infinite loop. Beyond that, this code was written with the assumption
that since the IPv6 packet already went through the generic IPv6 option
parser, several fields are guaranteed to be valid; but this assumption
does not hold because of the missing '+2', and there's as a result a
triggerable buffer overflow (write zeros after the end of the mbuf,
potentially to the next mbuf in memory since it's a pool).
Add the missing '+2', this place will be reinforced in separate commits.

When allocating memory through malloc(9), we always expect the amount of
memory requested to be unsigned as a negative value would either stand for
an error or an overflow.
Unsign some values, found when considering the use of mallocarray(9), to
avoid unnecessary casting. Also consider that indexes should be of
at least the same size/type as the upper limit they pretend to index.
