Rather than requiring a socket to be created as a TLS socket from the
get go, switch a TOE socket from "plain" TOE to TLS mode when a
receive key is added to the socket.
The firmware is only able to switch a "plain" TOE connection to TLS
mode if the head of the pending socket data is the start of a TLS
record, so the connection is migrated to TLS mode as a multi-step
process.
When TOE TLS RX is enabled, the associated connection's receive side
is frozen via a flag in the TCB. The state of the socket buffer is
then examined to determine if the pending data in the socket buffer
ends on a TLS record boundary. If so, the connection is migrated to
TLS mode and unfrozen. Otherwise, the connection is unfrozen
temporarily until more data arrives. Once more data arrives, the
receive queue is frozen again and rechecked. This continues until the
connection is paused at a record boundary. Any records received
before TLS mode is enabled are decrypted as software records.
Note that this removes the 'rx_tls_ports' sysctl. TOE TLS offload for
receive is now enabled automatically on existing TOE connections when
using a KTLS-aware SSL library just as it was previously enabled
automatically for TLS transmit. This also enables TLS offload for TOE
connections which enable TLS after passing initial data in the clear
(e.g. STARTTLS with SMTP).

These should all trigger errors when reading from the socket.
Tests include truncated records (socket closed early on the other
side), corrupted records (bits flipped in explicit IVs, ciphertext, or
MAC), invalid header fields, and various invalid record lengths.

If a TLS record is too small to contain the required explicit IV,
record_type (TLS 1.3), and MAC, reject attempts to decrypt it with
EMSGSIZE without submitting it to OCF. OCF drivers may not properly
detect that regions in the crypto request are outside the bounds of
the mbuf chain. The caller isn't supposed to submit such requests.

Some ACPI tables like XSDT contain pointers to other ACPI tables. When
an ACPI table is loaded by qemu's loader, the address in the guest
memory is unknown. For that reason, the qemu loader supports patching
those pointers. Basl keeps track of all pointers and causes the qemu
loader to patch all pointers.
The qemu ACPI table loader is unsupport yet. However, in a future commit
bhyve will use dynamic ACPI table offsets based on the size and
alignment requirements of each ACPI table. Therefore, tracking ACPI
table pointer is required too.

The qemu ACPI table loader patches the ACPI tables. After patching them,
checksums aren't correct any more. It has to calculate a new checksum
for the ACPI table. For that reason, basl has to keep track of checksums
and has to cause the qemu loader to create new checksums for the tables.
The qemu ACPI table loader isn't supported yet. However, the address of

creation. So, the checksum of tables which include pointer to other

Basl is the bhyve ASL compiler. At the moment, it's just a small wrapper
to call iasl, the Intel ASL compiler. As bhyve will gain support for
qemu's ACPI table loader in the future, it has to create ACPI tables on
it's own. Therefore, it makes sense to create a new file which keeps the
code for basl.
This first implementation of basl supports creating an ACPI table by
appending raw bytes to it. It's also capable of loading all tables into
guest memory.
