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.

The TI driver has been moved to RTEMS so the driver can be removed
from libBSD.
The following files have been removed from libBSD and moved to
RTEMS.
1) ti/am335x/am335x_scm_padconf.c
2) ti/am335x/am335x_scm_padconf.h
3) ti/ti_pinmux.c
4) ti/ti_pinmux.h
Update #3784
- The files in the i386 directory have been moved to common x86 directories by FreeBSD:
- freebsd/sys/i386/include/machine/bus.h
- freebsd/sys/x86/include/machine/legacyvar.h
- freebsd/sys/x86/include/machine/specialreg.h
- Add header files in rtemsbsd directory to direct compiler to new files
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.
There is a bug in the #ifdef regarding FDT so this file hasn't been
compiled. If that bug is solved, the driver doesn't work for some other
reason.
With the FDT-bug the driver hasn't been used by anyone. So just remove
it again.
