Due to all the changes, this is basically a new version for this
example. The main benefit is the use of sock_udp but also the client
side is now more robust and reliable.
The parameters required for the PSK and ECC (e.g. keys) modes are moved
to an unique header.
The integration of TinyDTLS for RIOT has been merged into the
development branch of the official repository.
It will be officially available on the master branch in the next
release of tinyDTLS.
Other minor updates:
- Support for the RIOT's memarray
- tinydtls/sha2 is removed from the compilation for giving priority
to RIOT's sha2 functions.
They can define PSEUDOMODULES which is used to populate BASELIBS.
It means they must be processed before using BASELIBS immediate value.
This moved the processing of all `Makefile.include` before using `BASELIBS`.
It is also moved before setting `BASELIBS` in `modules.inc.mk to keep the
order logical (it would work anyway thanks to deferred variables evaluation).
This fixes the problems for `make -C tests/unittests`
Build targets were using the immediate value of '$(BASELIBS)' before it was
actually set. bindist.inc.mk should also be processed before as it is adding
`BIN_USEMODULE` to `USEMODULE`.
This fixes use before define problems for:
* `make -C examples/hello-world`
* `make -C examples/bindist`
Include order for board and cpu was
1. cpu include
2. board include
3. board common includes
4. cpu common includes
Its now changed to:
1. board include
2. board common includes
3. cpu include
4. cpu common includes
Verifications:
There are no common headers names between boards and cpus.
Except native that has a 'periph_conf.h' in cpu instead of being in board.
While the current approach for garbage collection in the 6Lo reassembly
buffer is good for best-effort handling of
*fragmented* packets and nicely RAM saving, it has the problem that
incomplete, huge datagrams can basically DoS a node, if no further
fragmented datagram is received for a while (since the packet buffer is
full and GC is not triggered).
This change adds a asynchronous GC (utilizing the existing
functionality) to the reassembly buffer, so that even if there is no new
fragmented packet received, fragments older than `RBUF_TIMEOUT` will be
removed from the reassembly buffer, freeing up the otherwise wasted
packet buffer space.
- Remove file related functions from loader.
* All packages must be builtin.
- Remove os.tmpname.
- Interface with TLSF.
- Don't abort() when out of memory.
Support for monocypher as crypto library. Blazing fast performance, but
double the flash requirement compared to TweetNaCl. Stack usage is
around 70% of TweetNaCl
iotlab-m3 boards always ended up not being able to flash after time.
This changes managed to fix and flash boards that where able to be flashed with
the deprecated `ft2232` driver and not with the `ftdi` driver used in RIOT.
It combines configuration from openocd, iot-lab, RIOT config and Alexandre
Abadie feedback
* http://repo.or.cz/openocd.git/blob/HEAD:/tcl/interface/ftdi/iotlab-usb.cfg
* ftdi configuration
* https://github.com/iot-lab/iot-lab-gateway/blob/2.4.1/gateway_code/static/iot-lab-m3.cfg
* `trst_and_srst` config
* Alexandre feedback and http://openocd.org/doc/html/Reset-Configuration.html
* 'connect_assert_srst' reset configuration
* it prevents errors in the output on first flash
* should help on boards with invalid code
* It was taken from what Alexandre found for board 'b-l072z-lrwan1'
* It requires using '-c reset halt' instead of '-c halt' before debug
* RIOT
* Keep the `configure -rtos` auto
The new tool (mkconstfs2) features:
* more robust filename handling: no need for mangling,
and works on Windows.
* Better output generation: nothing is written in case
of failures.
* Allows more control over the files that are included:
- does not traverse directories, filenames must be explicitly
given.
- The "root" can be explicitly given (thus the tool can get
the same result independently of the CWD).
Thanks to MichelRottleuthner for making it work with Windows paths.
