Instead of retrieving a pointer with NETOPT_STATS, retrieve the current
data. This avoids data corruptions when reading from one thread (e.g.
the thread running the shell (ifconfig command)) while another thread
is updating it (e.g. the netif thread).
The issue affects all boards, as users typically expect the count of
TX packets and the number of TX bytes to refer to the same state. For
16 bit and 8 bit platforms even a single netstat entry can read back
corrupted.
This fixes the issue by just copying the whole netstat_t struct over
without requiring explicit locking on the user side. A multi-threaded
network stack still needs to synchronize the thread responding to
netopt_get with the thread writing to the netstat_t structure, but that
is an implementation detail no relevant to the user of the API.
In 04ab5a74f3 a bug was introduced in
the calculation of the GPIO port address by refactoring code. This
fixes the issue by extracting the GPIO port first from the pin.
Our AVR port doesn't make use of an ISR stack and just victimizes the
stack of whatever thread happens to be running, which in most cases is
the idle thread. Hence, the idle stack has to be large enough to
support the ztimer ISR.
drivers/mcp2515: enable filtering
The current driver implementation initializes the driver in a way to receive all the CAN messages without matching the filters. This commit changes that by adding a macro definition that will be enabling or disabling the filtering and accordingly set the appropriate mcp2515 acceptance mode
To allow a platform independent implementation of exceptions for different ESP32x SoC variants, the platform specific code for Xtensa based ESP SoCs is moved to a separate platform file `exception_xtensa.c`.
To allow a platform independent implementation of irq_arch for different ESP32x SoC variants, the platform specific code for Xtensa based ESP SoCs is moved to a separate module `esp_xtensa`.
To allow a platform independent implementation of tread_arch for different ESP32x SoC variants, the platform specific code for Xtensa based ESP SoCs is moved to a separate module `esp_xtensa`.
esp32 vendor code and atwinc15x0 both define conflicting spi_flash_{read, write} functions. esp32 already have build-in WiFi, so it's unlikely to ever use this driver - just blacklist the architecture.
An EUI provider can provide EUIs for multiple interfaces based on
their index.
For this is should get the index of the interface, not the index of
the EUI provider.
