This commit enables a node serve as the border agent of native commissioner
by adding the border agent UDP port to unsecure port when the security
policy allows.
To fully test verify this commit, we need a native commissioner, which I
will submit a separate commit to enable that.
mDidTx indicates whether a frame is received or transmitted, which is
only useful for capturing packets. This commit removes this field, and makes
this flag an argument to the pcap callback.
This commit changes the `SendOutOfBandFrameRequest()` implementation
to check `mOperation` and `mPending<>` state variables to determine
if MAC layer is still busy with a previous OOB tx request (instead of
using the `mOobFrame` pointer variable). This change makes the OOB tx
implementation behave similarly to other APIs (e.g., `ActiveScan()`
or `SendFrameRequest()`). This commit also enhances the documentation
for the OOB Send APIs in header files.
This commit refines Coap::Header into Coap::Message to avoid declaring
the big Coap::Header in stack which was causing problems in low-memory
systems such as CC2538.
A UDP reserves 56 bytes by default, which will not be used before an
outbound message goes down to transport layer and after an inbound
message is delievered to CoAP agent. To get better performance, this commit
utilizes these reserved bytes of cache basic header of CoAP message
including CoAP version, code, message ID and token. These cached data
are parsed when CoAP agent receives a CoAP message and are dumped into
the correct place of a CoAP Message before sending by lower layer.
To make sure there is enough reserved bytes for an inbound message, This
commit removes headers in UDP layer before delivering a ot::Message to
handlers.
Since RFC-7252 a number of additions have been made to the CoAP
Content-Format registry which is maintained by the IANA. This patch
updates the list in OpenThread. Notably:
- Standards references are made for each entry
- Some invalid assignments have been removed (notably PKCS10, PKCS7 and
JWS)
- New entries have been added for COSE, JSON patches, merge patches,
CBOR, CWT, CoAP groups, SENML and SENSML.
Thread defines UDP proxy as a feature to allow secure, two-way
communication of Thread Management Commands between the Commissioner
and any Thread Device in the Thread Network via the Border Agent.
This commit renames the existing UDP proxy feature which forwards UDP
packets back and forth between Host and NCP to UDP forward.
This commit updates the `radio.h` header file:
- Re-orders the definitions so keep the related functions close.
- Updates the documentation/comments.
- Uses `otPanId` and `otShortAddress` for function parameter types.
