This is quick solution to avoid wrapping around after 4294967 milliseconds.
It uses xtimer_now_usec64 instead of xtimer_now_usec.
Notice that this is more expansive than the previous solution, especially
on AVR systems.
This change is in preparation to [PR 10788]. PR 10788 will make the
shell exitable which may lead to unexpected behavior in comparison to
previous usage of the shell.
To prevent this, this PR introduces two "new" functions to the shell's
API: `shell_run_once()` and `shell_run_forever()`.
`shell_run_once()` basically has the same behavior as `shell_run()` in
current master: Start a shell and continue reading lines until EOF is
reached.
`shell_run_forever()` wraps around `shell_run_once()` and restarts the
shell if it exits.
`shell_run()` is re-introduced as a back-porting alias for
`shell_run_forever()`.
As a consequence all current calls to `shell_run()` won't exit even
with [PR 10788] merged (which would add EOT as additional exit
condition for `shell_run_once()`).
[PR 10788]: https://github.com/RIOT-OS/RIOT/pull/10788
TCP options have up to three fields (kind, length, value). The
current code only checks for the presence of the first field. Before
accessing the second field (length) the code must ensure that a length
field is even present.
A received packet is outputted in DEBUG _after_ it was already parsed,
but with a reference to the already parsed header. The result is that
there can be some garbage in the output and the packet is not dumped in
total. As without parsing we do not have access to the header yet, we
use the `gnrc_netif_addr_to_str()` helper function instead of parsing
the destination address by hand.
This commit changes the name of the requests over the control endpoints
to control requests instead of setup requests. This is a terminology fix
to follow the USB specification more closely as technically only the
first stage of a control request is named setup which contains a setup
packet. The whole transfer is a control transfer.
This enables 'pthread' support on arduino.
avr-libc C90 'time.h' does not include 'sys/types.h' as POSIX expects it.
However, the type previously defined conflicts with the one in
'cpu/atmega_common/avr_libc_extra/include/sys/types.h' when both are
included, so include 'sys/types.h'.
Maybe it should alway be included by 'time.h' but this
would need its specific review.
