Initialize addr with 0 first.
Otherwise if prefix is < 64 there will be random bits of stack memory
in the bits of the address that are neither touched by ipv6_addr_set_aiid()
nor ipv6_addr_init_prefix().
Add a minimal implementation of `strerror()`.
All other targets use either newlib or picolibc and provide this
function, add it to AVR so we can rely on it in common code.
There is no way to properly handle incorrect SPI parameters at run time, so
just having an assertion blow up is the better choice here.
As most instances of `spi_acquire()` don't check the return value anyway, this
will improve debugging experience quite a bit. Some implementation of
spi_acquire() don't even check parameters anyway.
This is a regression which was introduced in #16114, without resetting
the color the red color will be used for all following text written to
the terminal and will also cause the shell prompt etc. pp. to be colored
in red which is undesirable. This commit fixes this regression by using
the ANSI escape sequences to reset the color after the error message has
been written.
`uri_parser_process()` takes a `const char *` as input parameter but
the result is a struct of `char *` to the original string.
This may lead a user to modifying the strings in `uri_parser_result_t`
which will cause a crash if the original string resides in read-only
memory (and violates the no-modifications promise of the const parameter
in `uri_parser_process()`).
To fix this, make the resulting strings `const` as well, so nobody dares
to touch them in a writing way.
When a connection is aborted and the node in question is a slave
then it can be advertising/scanning at the time. The incoming
event triggers the state to be changed to IDLE but ongoing adv/scan
which will cause 'nimble_netif_conn_start_adv' to fail to allocate
a handle as the netif will still be busy. Therefore when
stop scan/stop before switching the state.
Sending a RA with ltime = 0 does not get us added to the default router
list, but the options (and therefore the RIO) are still parsed.
This even appears to work with Linux as a receiver.
SERCOM5 on SAM L21 does not support fractional baud rate mode.
Instead of special-casing it, just use arithmetic baud rate mode
in general on this CPU, as I'm not sure what the advantages of fractional
baud rate mode are.
