kernel: deprecate Internet Class A/B/C
Hide historical Class A/B/C macros unless IN_HISTORICAL_NETS is defined;
define it for user level. Define IN_MULTICAST separately from IN_CLASSD,
and use it in pf instead of IN_CLASSD. Stop using class for setting
default masks when not specified; instead, define new default mask
(24 bits). Warn when an Internet address is set without a mask.

Without this patch, the MSG_TLSAPPDATA flag would cause
soreceive_generic() to return ENXIO for any non-application
data record in a TLS receive stream.
This works ok for TLS1.2, since Alert records appear to be
the only non-application data records received.
However, for TLS1.3, there can be post-handshake handshake
records, such as NewSessionKey sent to the client from the
server. These handshake records cannot be handled by the
upcall which does an SSL_read() with length == 0.
It appears that the client can simply throw away these
NewSessionKey records, but to do so, it needs to receive
them within the kernel.
This patch modifies the semantics of MSG_TLSAPPDATA slightly,
so that it only applies to Alert records and not Handshake
records. It is needed to allow the krpc to work with KTLS1.3.

Widen the ifnet_detach_sxlock to cover the entire vnet sysuninit code.
This ensures that we can't end up having the vnet_sysuninit free the UDP
pcb while the detach code is running and trying to purge the UDP pcb.

The kernel RPC cannot process non-application data records when
using TLS. It must to an upcall to a userspace daemon that will
call SSL_read() to process them.
This patch adds a new flag called MSG_TLSAPPDATA that the kernel
RPC can use to tell sorecieve() to return ENXIO instead of a non-application
data record, when that is what is at the top of the receive queue.
I put the code in #ifdef KERN_TLS/#endif, although it will build without
that, so that it is recognized as only useful when KERN_TLS is enabled.
The alternative to doing this is to have the kernel RPC re-queue the
non-application data message after receiving it, but that seems more
complicated and might introduce message ordering issues when there
are multiple non-application data records one after another.
I do not know what, if any, changes will be required to support TLS1.3.

from libBSD.

RTEMS.

Update #3784
Some targets support only flushing or invalidating complete cache lines.
In this cases misaligned buffers might lead to unexpected results. This
patch adds a flag that allows drivers to signal to the bus dma driver
that it is OK to round a buffer to the next full cache line. That's for
example necessary if a driver wants to send out 14 byte via a USB DMA.
Only the driver knows whether these 14 bytes are located in an otherwise
unused cache line aligned buffer.
