The scheduler has a kernel-internal _pend_thread() utility which
sounds like a function which will add an arbitrary thread to a wait_q.
This is essentially unsupportable in SMP, where that thread might
actually be executing on a different CPU.
Thankfully we never used it like that. The only spots outside the
scheduler that use the API are in pipes and mailbox, which both just
want to pend a DUMMY thread to track the timeout but will never try to
pend a true foreign thread.
Clarify the comment and add an assertion to make sure this promise
isn't broken in the future.

This was the only spot where the scheduler-internal
_peek_first_pending_thread() API was used. Given that this kind of
thing is inherently racy (it may not be pending as long as you expect
if a timeout expires, etc...), it would be nice to retire it.
And as it happens all the queue code was using it for was to detect
the case of a non-empty wait_q over which it was looping, which is
trivial to do without API support.
Signed-off-by: Andy Ross <andrew.j.ross@intel.com>
The scheduler exposed two APIs to do the same thing:
_add_thread_to_ready_q() was a low level primitive that in most cases
was wrapped by _ready_thread(), which also (1) checks that the thread
_is_ready() or exits, (2) flags the thread as "started" to handle the
case of a thread running for the first time out of a waitq timeout,
and (3) signals a logger event.
As it turns out, all existing usage was already checking case #1.
Case #2 can be better handled in the timeout resume path instead of on
every call. And case #3 was probably wrong to have been skipping
anyway (there were paths that could make a thread runnable without
logging).
Now _add_thread_to_ready_q() is an internal scheduler API, as it
probably always should have been.
This also moves some asserts from the inline _ready_thread() wrapper
to the underlying true function for code size reasons, otherwise the
extra use of the inline added by this patch blows past code size
limits on Quark D2000.

Thread and interrupt events may well arrive before the subsystem
initialization call has been made. Just swallow such events.
In particular, an incoming change to the way _ready_thread works
causes the main and idle thread initialization to throw thread ready
events (which isn't wrong!), which the current setup can't handle.

Instead of CONFIG_COAP_MBEDTLS_SSL_MAX_CONTENT_LEN, use recently
introduced CONFIG_MBEDTLS_SSL_MAX_CONTENT_LEN.
Signed-off-by: Paul Sokolovsky <paul.sokolovsky@linaro.org>
This value allows to set max payload length of a TLS protocol
message, and passed thru to mbedTLS as MBEDTLS_SSL_MAX_CONTENT_LEN
setting. The only safe value is 16384, which translates to 32KB
of RAM required just for mbedTLS input/output buffers. Any other
value can be configured *only* per a particular application
(e.g. knowing that it won't pass more than spefific amount of
data at once and/or won't connect to a server with a long cert
chain). Previosuly, we had quite an adhoc and inflexible config
with random values for that setting, based on protocol.
Note that while the safe value is 16384, "backward compatible"
default of 1500 is used (good for DTLS on the other hand).

Problem:
cdc_acm sample outputs junk characters to the console when any key
is pressed. It is supposed to echo the same character as the input.
Analysis:
nRF52840 USB driver always reads 64 bytes from the USB peripheral's
local buffer irrespective of the data length. Even when 1 byte
is sent by the host, the usb driver receives as 64 bytes.
Since the maximum packet size value had been used when setting up
the EasyDMA's MAXCNT register for OUT transactions, DMA transffered
the entire 64 bytes of it's local buffer into the data RAM
irrespective of the OUT data length, containing garbage at the end
of useful payload. For some applications like hci_usb the extra
bytes were being ignored. But for cdc_acm, the entire 64 bytes
is getting echoed back displaying garbled characters on the terminal.
Fix:
For OUT endpoints, the amount of data received by USBD to its local
buffer should be read using SIZE.EPOUT[x] registers in the case of
BULK and INTERRUPT endpoints and SIZE.ISOOUT register for ISOOUT
endpoint. This value should be set to the EasyDMA maxcnt register
to DMA into RAM buffer. Fix this issue for Bulk, Interrupt and
ISOOUT endpoints.

The transfer API provides 'high' level functions to manage sending and
reception of USB data. A USB (class) driver has to register the generic
usb_transfer_ep_callback as endpoint status callback in order to use
the API.
With this API, the class driver does not need to take care of low-level
usb transfer management (packet splitting, ZLP, synchronization...).
The usb_transfer methods will split transfer into multiple transactions
depending endpoint max size and controller capabilities.
Once the transfer is completed, class driver is notified by a callback.
The usb_transfer method can be executed in IRQ/atomic context.
A usb_transfer synchronous helper exists which block-waits until
transfer completion.
In write case, a transfer is complete when all data has been sent.
In read case, a transfer is complete when the exact amount of data
requested has been received or if a short-pkt (including ZLP) is
received.
transfer methods are thread-safe.
A transfer can be cancelled at any time.
