Since RIOT is an operating system the native binary will never terminate
[0]. The termination condition for fuzzing GNRC is that the packet was
handled by the network stack and therefore freed. If it is never freed
we will deadlock meaning a memory leak was found, afl should be able to
detect this through timeouts.
This is currently only supported for gnrc_pktbuf_malloc since this is
the pktbuf implementation I used for fuzzing. Implementing this in
pktbuf.h is not possible.
[0]: Except NATIVE_AUTO_EXIT is defined, however, even with that define
set RIOT will only terminate when all threads terminated. Unfortunately,
gnrc_udp and other network threads will never terminate.
This adds a utility module which is used to write applications for
fuzzing RIOT network modules. The module provides a dummy network
interface which is configured with a static IPv6 addresses for modules
which perform operations on the underlying network interface. Besides,
it contains a utility function for transforming data received on
standard input into a `gnrc_pktsnip_t`.
This adds a driver for the ST M95xxx series SPI EEPROMs.
The driver has been tested with the M95M01 EEPROM, but should
work with other chips from that family.
SPI-EEPROMs from other vendors from the families AT25xxx, 25AAxxx,
25LCxxx, CAT25xxx & BR25Sxxx should also in the same way.
The CPU has 4 hardware timers.
Configuration for all 4 timers exists, but the compile-time range
check has an off-by-one error, causing the last timer to remain
inaccessible.
Native supports multiple ZEP devices, so add a config option for it to
gnrc_border_router.
This allows for easier testing of border routers with multiple interfaces.
On some boards, button 0 does not exist so BTN0_PIN is not defined, but
these boards may define other buttons.

This commit enables Cortex-M CPU interrupt sub-priorities
and allows the PendSV interrupt to have a priority different
from the default one. Together these two preprocessor
defines can be used to have PendSV always run as the last interrupt
before returning from the interrupt stack back to the user space.
Running PendSV as the last interrupt before returning to the
user space is recommended by ARM, as it increases efficiency.
Furthermore, that change enhances stability a lot with the
new nRF52 SoftDevice support, currently being worked in
PR #9473.
This commit merely enables sub-priorities and a separate
PendSV priority to be used without changing the default
RIOT behaviour.
There were two subtle bugs that prevented the DHCPv6 client to request
multiple prefixes for different interfaces.
- `dhcpv6_client_req_ia_pd()` would fill up *all* leases with the same interface
- `_parse_reply()` would return after parsing the first answer
With this patch, `gnrc_border_router` gets a prefix on both interfaces of the at86rf215.
