Generate a module for arduino sketches in a subfolder of BINDIR.
This prevents issues when doing concurrent builds or out of tree build with
readonly sources.
Declare all generated files as `BUILDDEPS` to be re-created after
`clean` on parrallel `clean all`.
When a keepalive timeout occurs keepalive_retry_cnt remains zero,
so when the connection is re-established _on_keepalive_evt will
immediately disconnect instead of actually sending a keepalive ping.
The sequence looks like:
1. _on_connack: start con->keepalive_timer
2. Server does not respond to keepalive pings
3. _on_keepalive_evt: con->keepalive_retry_cnt reaches zero
4. Connection torn down and ASYMCUTE_DISCONNECTED sent to application
5. Application starts reconnection
6. _on_connack: start con->keepalive_timer again
7. First _on_keepalive_evt: con->keepalive_retry_cnt is still zero
8. Repeat from 4.
So this simply resets keepalive_retry_cnt in _on_connack when
the keepalive timer is restarted. It's a new connection, so
resetting the keepalive retry counter make senses regardless.

With the increase of the message queue size from 8 to 16 in
946b06e4f0, the default stack became too small.
This changes the stack size to grow with the message queue size.
The cc110x driver has been re-written from scratch to overcome the limitations
of the old driver. The main motivation of the rewrite was to achieve better
maintainability by a detailed documentation, reduce the complexity and the
overhead of the SPI communication with the device, and to allow to
simultaneously use transceivers with different configuration regarding the used
base band, the channel bandwidth, the modulation rate, and the channel map.
Features of this driver include:
- Support for the CC1100, CC1101, and the CC1100e sub-gigahertz transceivers.
- Detailed documentation of every aspect of this driver.
- An easy to use configuration API that allows setting the transceiver
configuration (modulation rate, channel bandwidth, base frequency) and the
channel map.
- Fast channel hopping by pre-calibration of the channels during device
configuration (so that no calibration is needed during hopping).
- Simplified SPI communication: Only during start-up the MCU has to wait
for the transceiver to be ready (for the power regulators and the crystal
to stabilize). The old driver did this for every SPI transfer, which
resulted in complex communication code. This driver will wait on start up
for the transceiver to power up and then use RIOT's SPI API like every other
driver. (Not only the data sheet states that this is fine, it also proved to
be reliable in practise.)
- Greatly reduced latency: The RTT on the old driver (@150 kbps data rate) was
about 16ms, the new driver (@250 kbps data rate) has as RTT of ~3ms
(depending on SPI clock and on CPU performance) (measured with ping6).
- Increased reliability: The preamble size and the sync word size have been
doubled compared to the old driver (preamble: 8 bytes instead of 4,
sync word: 4 byte instead of 2). The new values are the once recommended by
the data sheet for reliable communication.
- Basic diagnostic during driver initialization to detect common issues as
SPI communication issues and GDO pin configuration/wiring issues.
- TX power configuration with netdev_driver_t::set() API-integration
- Calls to netdev_driver_t::send() block until the transmission has completed
to ease the use of the API (implemented without busy waiting, so that the
MCU can enter lower power states or other threads can be executed).
- Removed cc110x driver
- Updated all makefiles
- Kept both board specific configurations and support for it in RIOT's
upper layers, so re-implementations don't need to start from zero
CTRL-C cancels the current line, similar to how getty works.
This is useful if one is using a dumb terminal to communicate with
a node, as it saves having to repeatedly type backspace to discard the
current line. It also helps when connecting to an already running node,
as one does not know what is on the line buffer, the safest thing to do
is to begin by sending a ctrl-C.
This is a suggestion of @benemorius.
Add an implementation that waits for 's' to print 'START' and return.
If 'r' is given is prints 'READY' to allow querying for state.
The help and answered string have to be different to not match the other.
Using puts/getchar was smaller than using `stdio_read/stdio_write` on the
example I tested with `esp32`.
From the gnrc_pktbuf_mark documentation:
It's not guaranteed that `result->data` points to the
same address as the original `pkt->data.
Thus it should be necessary to update the `hdr` pointer.
if xtimer_set spins the callback is executed in the thread context.
comment to explain irq_disable
and when this line could be removed
(when xtimer stops executing the callback funtion from thread context)
If an address was pre-configured by the upper layer its validity is
currently ignored. It is neither checked if the address is on the
interface at all nor is it checked if it is valid.
This change provides a fix for that by checking both facts.
A proper error code is returned if a key with unsupported (either by the implementation or the AES algorithm) length is passed to aes_init.
This fixes Issue #10175
The length field in an MQTT packet carries the _total_ length of the
packet. If it is below 256 (i.e. fits in one byte) only one byte is
used for the length field. If it is larger than that 3 bytes are used,
with the first byte having the value `0x01` and the remaining bytes
representing the length in as a 2 byte unsigned integer in network byte
order. Resulting from that it can be assessed that the check in
`emcutes`'s `set_len()` function is wrong as it needs to be checked if
`len` is lesser or equal to `0xff - 1`. `len <= (0xff - 1)` can be
simplified to `len < 0xff`. For some larger packages this safes 2 bytes
of wasted packet space.
`len` is used with the `memcpy()` to copy the payload to `tbuf`. With a
payload provided that is just long enough to fill `tbuf`, `len += 6`
leads to the `memcpy()` overriding data after `tbuf` (e.g. the
`mutex` that is unlocked right after) and thus resulting in potential
segmentation faults.
Additionally `+ 6` can only be applied if the total packet length is
below 256 (see spec), so `len + pos` is what needs to be provided to the
corresponding send functions instead (`pos` adapts to the header length
of the PUBLISH message).
Unstructured static initializer like { 0 } lead to compilation errors on ESP8266, MSP430 and MIPS. Error messages are:
error: (near initialization for 'queue.event_list') [-Werror=missing-braces]
error: (near initialization for 'queue.waiter') [-Werror=missing-field-initializers]
This change fixes the compilation problem.
Check for the usage of `newlib_nano` module instead of the
`USE_NANO_SPECS` variable.
This allows also benefiting from the `printf_float` and `scanf_float`
behaviour on `arm7` and `riscv` cpus.

stm32eth: Move to stm32_common periph
cpu/stm32_periph_eth: Rebase to current master branch
- Update DMA to use new vendor headers
- Update send to use iolist. It looks like the packet headers are now transfered as seperate iolist entries which results in the eth periph sending each header as own packet. To fix this a rather ugly workaround is used where the whole iolist content is first copied to a static buffer. This will be fixed soon in another commit

When reworking the reception of IPv6 packets I reset a previously set
`ipv6` snip as follows when the IPv6 extension handler returns a
packet (see first hunk of this commit):
```C
ipv6 = pkt->next->next
```
With `gnrc_ipv6_ext` this makes *somewhat* sense, `pkt->next` was
previously equal to `ipv6` and after the function call `pkt->next`
is the marked extension header, while `pkt->next->next` is the IPv6
header. However, since `ipv6` is already write-protected i.e.
`ipv6->users == 1` (see ll. 665-675), any additional call of
`gnrc_pktbuf_start_write()` [won't][start-write-doc] duplicate the
packet. In fact, the only `gnrc_pktbuf_start_write()` in
`gnrc_ipv6_ext` is used to send the *result* to the subscribers of that
extension header type, leaving the original packet unchanged for the
caller. As such `ipv6` remains the pointer to the IPv6 header whether
we set it in the line above or not. So we actually don't need that
line.
However, the extension header handling also returns a packet when
`gnrc_ipv6_ext` is not compiled in. In that case it is just a dummy
define that returns the packet you give provide it which means that
this still holds true: `pkt->next == ipv6`.
So setting `ipv6` in this case is actually harmful, as `ipv6` now
points to the NETIF header [following the IPv6 header][pkt-structure]
in the packet and this causes the `user` counter of that NETIF header
`hdr` to be decremented if `hdr->users > 1` in the write-protection I
removed in hunk 2 of this commit:
```C
/* pkt might not be writable yet, if header was given above */
ipv6 = gnrc_pktbuf_start_write(ipv6);
if (ipv6 == NULL) {
DEBUG("ipv6: unable to get write access to packet: dropping it\n");
gnrc_pktbuf_release(pkt);
return;
}
```
But as we already established, `ipv6->users` is already 1, so we don't
actually need the write protection here either.
Since the packet stays unchanged after the `ipv6` snip, we also don't
need to re-search for `netif_hdr` after the other two lines are
removed.

Summary for Users
=================
Deprecation is scheduled for 2020.01.
Users which depend on this module and cannot switch libraries may copy
the code into to their own application.
As expressed in PR #11724, the UBJSON module has issues which are not easy
or worth fixing.
Before removing the module, it should be marked as deprecated to give users
time to either migrate to another library, or copy the code to their own
private repo.
The deprecation warning has been supressed from the unit tests. This has the
ugly side-effect of supressing deprecation warning in other unit tests too,
but that should not last long, only until the module is finally deleted.
The `addr` parameter of the NIB's `_handle_dad()` function can come
from anywhere (e.g. in the fallback to classic SLAAC the destination
address of the IP header is used), so putting that pointer in a timer
is not a good idea. Instead we use the version of the address that is
stored within the interface.
The API of `tsrb` was changed because of confusing type situations.
This API change takes this API change of changing `char` to `uint8_t`
up a level. Since `isrpipe` most often is used together with
`periph_uart` this change even is beneficial, as `periph_uart` also
uses `uint8_t` instead of `char`.
Having the input type `char` makes the output of `tsrb_get_one()`
incomparable to the input of `tsrb_add_one()`. By changing it to
`uint8_t` we not only definitively fix it to an octet, but also ensure
that the input and output are the same.
To read float number from stdin, add "-u scanf_float"
option to the linker.
This option is setup using a pseudomodule as it is already done for
printf_float.
Just add to your Makefile:
USEMODULE += scanf_float

`_demux()` might change `pkt->data` in all kind of ways (moving it due
to `gnrc_pktbuf_mark()`, though unlikely; releasing it, because e.g. it
starts with a fragment header that marks a fragmented packet containing
only one fragment, etc.) so accessing the pointer *after* calling
`_demux()` is somewhat playing with fire. This change avoids this by
storing the value of `ext_hdr->nh` (all we are interested in here) in a
temporary variable that then is used to set the out-parameter `nh`.
`protnum` needs to be unchanged before the call to `_demux()` as it was
set by the previous iteration and determines what extension header
actually is handled.
