Add in a new function coap_io_get_fds() to get the lists of (internal
to libcoap) file descriptors that are in a read or write pending state,
as well as the timeout time for the next internal to libcoap activity
(e.g. packet retransmission).
Tag server returned data with a digest computed ETag option value so
requests with an ETag option can return 2.03 if there is a match.
The size of bytes hash that is computed for the ETag can be overwritten by
localy defining COAP_ETAG_MAX_BYTES to be a value between 1 and 8 bytes
inclusive. It is set to 4 by default.
Do not write the absolute build path into libcoapTargets.cmake. The
libcoapTargets.cmake is supposed to be packaged and installed by
distros. An absolute path referring to the build directory looks
therefore wrong.
Some build frameworks like Yocto have quality assurance check which
handle these issues as a warning or as an error. Example:
WARNING: libcoap-4.3.4-r0 do_package_qa: QA Issue:
File /usr/lib/cmake/libcoap/libcoapTargets.cmake in package
libcoap-dev contains reference to TMPDIR [buildpaths]
Declaring this header files as build interface looks like the right fix.
In case of a bundled tinytls library the header files should be handled
like the header files from libcoap itself: Either in the build folder of
libcoap or in /usr/include as declared one line above.
If an Observe is de-registered, but an unsolicited Observe response is received
before the de-register response is received, then the unsolicited response
failed to get decrypted.
Stop MbedTLS continuing to try to establish a (D)TLS session where the
server keeps on sending back a Server-Hello when it fails to decrypt
a client handhake (i.e. mismatch on PSK).
New examples/zephyr directory that contains a sample coap-client.
Building the coap-client assumes that the zephyrproject has already been
installed and set up (default directory ~/zephyrproject).
Update stateless token to track 20 bits - the largest no of blocks
as per RFC7959.
Make output of data detail configurable for coap_show_pdu().
Add in new function coap_enable_pdu_data_output() to do this.
Add -x option to coap-client and coap-server to enable this dropping
of data detail.
by:
- Correcting Contiki-NG's value of COAP_DEFAULT_MAX_PDU_RX_SIZE
- Denying to create PDUs longer than COAP_DEFAULT_MAX_PDU_RX_SIZE
- Using the MTU setter, thereby not overriding stack-specific limits
- Using existing constants for L4-specific header sizes
Server enabled for mcast receipt. When the server is acting as a proxy
sends a mcast packet out over a slave client type socket, it receives
the mcast packet on the server socket (which could then be forward out
of the client socket....).
This change prevents the server socket from passing up the libcoap stack
a mcast packet that it knows the client socket is sending.
./autogen.sh and ./configure no longer need to be run prior to running
make for Contiki, LwIP or RIOT from the appropriate examples sub-directory.
scripts/fix_version.sh now handles updating coap.h for the different
LIBCOAP_ and PACKAGE_ definitions.
Group together and document the run-time checks available for checking
the libcoap built-in functionality based on the ./cconfigure and / or
CMakeLists.txt options.
Create include/coap3/coap_defines.h file that contains a list of
COAP_ #defines created from the options defined when running ./configure
or cmake.
Add additional coap_*_is_supported() functions.
Tidy up the general proxy logic by moving common functionality
into libcoap.
New functions coap_proxy_forward_request(), coap_proxy_forward_response()
and coap_proxy_is_supported() added.
New --enable-proxy-code support added to configure.
New ENABLE_PROXY_CODE support added to CMakeLists.txt.
Support for common shared connection to next hop.
Support for round-robin balancing across multiple next hops.
Only support changing the client's source port if the DTLS library
has support / configured for CID.
Used when debugging server handling source address changes and CID
is in use.
Add in support for TinyDTLS (Client only) if TinyDTLS is patched
appropriately (not currently available on TinyDTLS main branch).
Add in new function coap_dtls_cid_is_supported().
'make distclean' removes header files built from the .in files, which
means that they are not available for different OS builds.
The same is true for CMakeLists.txt.
Remove the need for the .in files and update for libcoap revisions
by using a new script scripts/fix_version.sh created from
scripts/fix_version.sh.in.
CI has been updated to check revisions have been updated in the
appropriate places.
Do not remove libcoap-3.sym and libcoap-3.map when doing 'make distclean'
as they are git tracked files.
