Now that the LwM2M library can parse across multiple fragements,
let's remove the larger than normal buffer size setting.
Signed-off-by: Michael Scott <michael.scott@linaro.org>
The existing LwM2M framework expected contiguous buffers and this
was the reason for the 384 byte buffer sizes. This was previously
a limitation of the ZoAP API. The new CoAP API doesn't have this
limitation and the LwM2M library has already been migrated to use
it.
Let's finish the process by replacing any contiguous buffer handling
with the correct net_pkt APIs to parse across multiple fragments.

Two tests were on the knife-edge of their current stack limit and
were overflowing when UART system calls were added and userspace
enabled.
Test case stack sizes are often pulled out of thin air, the current
value of 256 was just a guess.
Kick these stacks up to 384; verified with sanitycheck --all that
this doesn't break anything.

The checking for spi_transceive() is fairly complex as we have to

The page_layout API returns pointers to kernel memory and is not
exposed to user mode. This is fine for flash_get_page_count()
and flash_get_page_info APIs since these copy the values, but some
redesign work will be needed to get flash_page_foreach() working in
user mode since we do not want the callback running in a privileged
state.
Due to the way that (even unimplemented) system call prototypes are
generated, the definition of struct flash_pages_info needed to be
moved outside of the #ifdef.

Straightforward conversion for adc_enable/disable.
adc_read() uses a sequence table, which points to an array
of struct adc_seq_entry, each element pointing
to memory buffers. Need to validate all of these as being readable
by the caller, and the buffers writable.

i2c actually only has two entry points into the driver,
i2c_configure and i2c_transfer. All the other APIs are derived
from these.
All derived APIs now just call i2c_transfer() with appropriate args.
The handler for i2c_transfer() needs to examine the message array
and validate all the buffers involved depending on whether we are
reading or writing to them.

In bind_default(), a local variable is passed to find_available_port().
However, the port number is unpredictable as it's not initialized and
will be used directly if not zero. This will lead to problems if the
port number is already used.
This patch makes find_available_port() always returns an available port
regardless of the port number in the sockaddr parameter.

The Designware FIFO is filled in units of 32 bit words, but the buffer
we are passed is not guaranteed to be a multiple of 4 bytes long, nor
aligned on a 4-byte boundary. So in theory we are reading 0-3 bytes
of unused garbage from the end of the array.
That's currently benign on supported platforms with this hardware,
which all support misaligned reads. But not all do. And the incoming
arrival of memory protection opens the possibility that those extra
bytes would cross a protection boundary and cause a crash or security
bug.
Do this right.
(Note that this is fixed to little endian byte order. The Designware
databook is frustratingly silent on the endianness it expects, but
existing hardware I can see is definitely LE and I see a few spots in
the Linux dwc2 driver that likewise assume LE).

The designware hardware in dedicated FIFO mode (which is all we
support right now for lack of shared-FIFO hardware) has one hardware
FIFO per IN (i.e. transmit) endpoint. But it doesn't assign them on
its own, it's the drivers responsibility to populate the TxFNum field
of the DIEPCTL registers with integer indices corresponding to the
desired FIFO.
We weren't doing that, which meant that all IN endpoints were sharing
the same FIFO zero which is supposed to be dedicated to EP0 control
transfers. The net effect is that sometimes outbound transfers would
be corrupted, showing data from the wrong endpoint. More often that
not this would leak from control transfers over to the
higher-bandwidth bulk endpoints of the application, but occasionally
you'd see a control transfer itself get borked and the USB device
would glitch.
Get this right and set the FIFOs properly.
