cc2538: rf driver doesn't handle large packets #5719
Comments
Might be, that the driver returns the wrong value for |
The NETOPT_MAX_PACKET_SIZE is ok, the mtu is 127 byte. |
This should not be done by the driver, but it happens only with the cc2538. |
The maximum size of for packets is done by the driver (some devices like the xbee e.g. are not able to send a full-sized IEEE 802.15.4 frames). The size should be 127 - mac header, so 127 is definitely too big (should be 102 IIRC) |
Yes I understand what do you mean, the payload size of the cc2538 is 102 as the at86rf2xx one, but the 6lowpan standard defines the mtu at 1280, doesn't it? In fact it works for the at86rf2xx. |
You are confusing MTU (on IP layer) with the maximum payload length of a radio frame right now ;-). 102 is the maximum payload length an IEEE 802.15.4 radio can send in a frame (at least in the configuration we run them). 1280 is the size an IPv6 packet over IEEE 802.15.4 can have at maximum. But if it is the same as the at86rf2xx, it must be something else in communication with the device... The 6LoWPAN implementation is pretty loosely coupled to the device. Except address information ( |
Just a pretty wild guess, but if the cc2538 driver cannot handle packets coming in rather quickly back to back, this could also lead to the mentioned problem. Edit: should have read more carefully, receiving seems to work somehow, since the device is responding. |
Anyway, enabling |
Yes sorry, I said that badly.
I will do some tests. Thank you a lot.
Ok! I will post the results in the next days. |
I will need to look at this more closely when I get time, but I suspect that @OlegHahm is correct - it's probably because the driver does not handle multiple frames in the RX FIFO. |
The error you describe above is actually caused by the driver tripping over it's own feet trying to respond to the ping - the ping query is received okay, but it doesn't wait for the first reply packet to finish sending before attempting to send the second one. This issue is described (and addressed) more fully in #5725. You'll still hit the RX FIFO problem described above, though, once you increase the ping payload enough (at least ~177 bytes). This is a little trickier to handle since we need to deal with multiple packets arriving in the RX FIFO. |
Sorry, but I thought this has been resolved by #5803... I have tested with that PR, I can't ping with large packets. |
Even if that would fix it, the normal workflow would be to close the issue after the fix was merged to master ;-) |
Received, I'm sorry. |
No problem :-) |
@LucaZulberti are you able to test whether this issue still exists in master? |
@aeneby Sure, I can test this, but not before Thursday. Il 10 Ottobre 2016 23:07:34 CEST, Aaron Sowry notifications@github.com ha scritto:

RIOT-2016.10 - Release Notes ============================ RIOT is a real-time multi-threading operating system that supports a range of devices that are typically found in the Internet of Things: 8-bit microcontrollers, 16-bit microcontrollers and light-weight 32-bit processors. RIOT is based on the following design principles: energy-efficiency, real-time capabilities, small memory footprint, modularity, and uniform API access, independent of the underlying hardware (this API offers partial POSIX compliance). RIOT is developed by an international open source community which is independent of specific vendors (e.g. similarly to the Linux community) and is licensed with a non-viral copyleft license (LGPLv2.1), which allows indirect business models around the free open-source software platform provided by RIOT. About this release: =================== This release provides a lot of new features as well as it fixes several major bugs. Among these new features are the new simplified network socket API called sock, the GNRC specific CoAP implementation gcoap and several new packages: TinyDTLS, the Aversive++ microcontroller library for robotics, the u8g2 graphic library, and nanocoap. Using the new sock API an implementation of the Simple Time Network Protocol (SNTP) was also introduced, allowing for time synchronization between nodes. New platforms include the Arduino Uno, the Arduino Duemilanove, the Arduino Zero, SODAQ Autonomo, and the Zolertia remote (rev. B). The most significant bug fix was done in native which led to a significantly more robust handling of ISRs and now allows for at least 1,000 native instances running stably on one machine. About 263 pull requests with about 398 commits have been merged since the last release and about 42 issues have been solved. 37 people contributed with code in 100 days. 1006 files have been touched with 166500 insertions and 26926 deletions. Notations used below: ===================== + means new feature/item * means modified feature/item - means removed feature/item New features and changes ======================== General ------- * Verbose behavior for assert() macro Core ---- + MPU support for Cortex-M API changes ----------- + Socket-like sock API (replacing conn) * netdev2: Add Testmodes and CCA modes * IEEE 802.15.4: clean-up Intra-PAN behavior * IEEE 802.15.4: centralize default values * gnrc_pktbuf: allow for 0-sized snips + gnrc_netapi: mbox and arbitrary callback support System libraries ---------------- No new features or changes Networking ---------- + Provide sock-port for GNRC + gcoap: a GNRC-based CoAP implementation + Simple Network Time Protocol (RFC 5905, section 14) + Priority Queue for packet snips + IPv4 header definitions Packages -------- + nanocoap: CoAP header parser/builder + TinyDTLS: DTLS library + tiny-asn1: asn.1/der decoder + Aversive++ microcontroller programming library + u8g2 graphic library Platforms --------- + Support for stm32f2xx MCU family + Low power modes for samd21 CPUs + More Arduino-based platforms: + Arduino Uno + Arduino Duemilanove + Arduino Zero + More boards of ST's Nucleo platforms: + ST Nucleo F030 board support + ST Nucleo F070 board support + ST Nucleo F446 board support + SODAQ Automono + Zolertia remote rev.

Changing to lower precision would save some memory. #4048: potential racey memory leak: According to the packet buffer stats, flood-pinging a multicast destination may lead to a memory leak due to a race condition. However, it seems to be a rare case and a completely filled up packet buffer was not observed. #4388: POSIX sockets: open socket is bound to a specific thread: This was an inherit problem of the conn API under GNRC. Since the POSIX sockets are still based on conn for this release, this issue persists #4527: gnrc_ipv6: Multicast is not forwarded if routing node listens to the address (might still be fixable for release, see #5729, #5230: gnrc ipv6: multicast packets are not dispatched to the upper layers) #5016: gnrc_rpl: Rejoining RPL instance as root after reboot messes up routing #5055: cpuid: multiple radios will get same EUI-64 Nodes with multiple interfaces might get the same EUI-64 for them since they are generated from the same CPU ID. #5656: Possible Weakness with locking in the GNRC network stack: For some operations mutexes to the network interfaces need to get unlocked in the current implementation to not get deadlocked. Recursive mutexes as provided in #5731 might help to solve this problem. #5748: gnrc: nodes crashing with too small packet buffer: A packet buffer of size ~512 B might lead to crashes. The issue describes this for several hundret nodes, but agressive flooding with just two nodes was also shown to lead to this problem. #5858: gnrc: 6lo: potential problem with reassembly of fragments: If one frame gets lost the reassembly state machine might get out of sync ### NDP is not working properly #4499: handle of l2src_len in gnrc_ndp_rtr_sol_handle: Reception of a router solicitation might lead to invalid zero-length link-layer addresses in neighbor cache. #5005: ndp: router advertisement sent with global address: Under some circumstances a router might send RAs with GUAs. While they are ignored on receive (as RFC 4861 specifies), RAs should have link-local addresses and not even be send out this way. #5122: NDP: global unicast address on non-6LBR nodes disappears after a while: Several issues (also see #5760) lead to a global unicast address effectively being banned from the network (disappears from neighbor cache, is not added again) #5467: ipv6 address vanishes when ARO (wrongly) indicates DUP caused by outdated ncache at router #5539: Border Router: packet not forwarded from ethos to interface 6 #5790: ND: Lost of Global IPV6 on node after sending lot of UDP frame from BR Timer related issues -------------------- #4841: xtimer: timer already in the list: Under some conditions an xtimer can end up twice in the internal list of the xtimer module #4902: xtimer: xtimer_set: xtimer_set does not handle integer overflows well #5338: xtimer: xtimer_now() not ISR safe for non-32-bit platforms. #5928: xtimer: usage in board_init() crashes: some boards use the xtimer in there board_init() function. The xtimer is however first initialized in the auto_init module which is executed after board_init() #6052: tests: xtimer_drift gets stuck: xtimer_drift application freezes after ~30-200 seconds native related issues --------------------- #495: native not float safe: When the FPU is used when an asynchronous context switch occurs, either the stack gets corrupted or a floating point exception occurs. #2175: ubjson: valgind registers "Invalid write of size 4" in unittests #4590: pkg: building relic with clang fails. #5796: native: tlsf: early malloc will lead to a crash: TLSF needs pools to be initialized (which is currently expected to be done in an application). If a malloc is needed before an application's main started (e.g. driver initialization) the node can crash, since no pool is allocated yet. other platform related issues ----------------------------- #1891: newlib-nano: Printf formatting does not work properly for some numberic types: PRI[uxdi]64, PRI[uxdi]8 and float are not parsed in newlib-nano #2006: cpu/nrf51822: timer callback may be fired too early #2143: unittests: tests-core doesn't compile for all platforms: GCC build-ins were used in the unittests which are not available with msp430-gcc #2300: qemu unittest fails because of a page fault #4512: pkg: tests: RELIC unittests fail on iotlab-m3 #4522: avsextrem: linker sometimes doesn't find `bl_init_clks()` #4560: make: clang is more pedantic than gcc oonf_api is not building with clang.

@LucaZulberti, @alignan within the scope of release testings I pinged with large packets between remote-revb and phytec boards as well as remote-reva and samr21-xpro boards and had great success regarding error rates. Could you check if this issue still persists please? |
Hi Peter, I've flashed the gnrc_networking example on a CC2538 based board and a samr21-xpro board. |
Great! Thanks for testing again. |

Changing to lower precision would save some memory. RIOT-OS#4048: potential racey memory leak: According to the packet buffer stats, flood-pinging a multicast destination may lead to a memory leak due to a race condition. However, it seems to be a rare case and a completely filled up packet buffer was not observed. RIOT-OS#4388: POSIX sockets: open socket is bound to a specific thread: This was an inherit problem of the conn API under GNRC. Since the POSIX sockets are still based on conn for this release, this issue persists RIOT-OS#4527: gnrc_ipv6: Multicast is not forwarded if routing node listens to the address (might still be fixable for release, see RIOT-OS#5729, RIOT-OS#5230: gnrc ipv6: multicast packets are not dispatched to the upper layers) RIOT-OS#5016: gnrc_rpl: Rejoining RPL instance as root after reboot messes up routing RIOT-OS#5055: cpuid: multiple radios will get same EUI-64 Nodes with multiple interfaces might get the same EUI-64 for them since they are generated from the same CPU ID. RIOT-OS#5656: Possible Weakness with locking in the GNRC network stack: For some operations mutexes to the network interfaces need to get unlocked in the current implementation to not get deadlocked. Recursive mutexes as provided in RIOT-OS#5731 might help to solve this problem. RIOT-OS#5748: gnrc: nodes crashing with too small packet buffer: A packet buffer of size ~512 B might lead to crashes. The issue describes this for several hundret nodes, but agressive flooding with just two nodes was also shown to lead to this problem. RIOT-OS#5858: gnrc: 6lo: potential problem with reassembly of fragments: If one frame gets lost the reassembly state machine might get out of sync ### NDP is not working properly RIOT-OS#4499: handle of l2src_len in gnrc_ndp_rtr_sol_handle: Reception of a router solicitation might lead to invalid zero-length link-layer addresses in neighbor cache. RIOT-OS#5005: ndp: router advertisement sent with global address: Under some circumstances a router might send RAs with GUAs. While they are ignored on receive (as RFC 4861 specifies), RAs should have link-local addresses and not even be send out this way. RIOT-OS#5122: NDP: global unicast address on non-6LBR nodes disappears after a while: Several issues (also see RIOT-OS#5760) lead to a global unicast address effectively being banned from the network (disappears from neighbor cache, is not added again) RIOT-OS#5467: ipv6 address vanishes when ARO (wrongly) indicates DUP caused by outdated ncache at router RIOT-OS#5539: Border Router: packet not forwarded from ethos to interface 6 RIOT-OS#5790: ND: Lost of Global IPV6 on node after sending lot of UDP frame from BR Timer related issues -------------------- RIOT-OS#4841: xtimer: timer already in the list: Under some conditions an xtimer can end up twice in the internal list of the xtimer module RIOT-OS#4902: xtimer: xtimer_set: xtimer_set does not handle integer overflows well RIOT-OS#5338: xtimer: xtimer_now() not ISR safe for non-32-bit platforms. RIOT-OS#5928: xtimer: usage in board_init() crashes: some boards use the xtimer in there board_init() function. The xtimer is however first initialized in the auto_init module which is executed after board_init() RIOT-OS#6052: tests: xtimer_drift gets stuck: xtimer_drift application freezes after ~30-200 seconds native related issues --------------------- RIOT-OS#495: native not float safe: When the FPU is used when an asynchronous context switch occurs, either the stack gets corrupted or a floating point exception occurs. RIOT-OS#2175: ubjson: valgind registers "Invalid write of size 4" in unittests RIOT-OS#4590: pkg: building relic with clang fails. RIOT-OS#5796: native: tlsf: early malloc will lead to a crash: TLSF needs pools to be initialized (which is currently expected to be done in an application). If a malloc is needed before an application's main started (e.g. driver initialization) the node can crash, since no pool is allocated yet. other platform related issues ----------------------------- RIOT-OS#1891: newlib-nano: Printf formatting does not work properly for some numberic types: PRI[uxdi]64, PRI[uxdi]8 and float are not parsed in newlib-nano RIOT-OS#2006: cpu/nrf51822: timer callback may be fired too early RIOT-OS#2143: unittests: tests-core doesn't compile for all platforms: GCC build-ins were used in the unittests which are not available with msp430-gcc RIOT-OS#2300: qemu unittest fails because of a page fault RIOT-OS#4512: pkg: tests: RELIC unittests fail on iotlab-m3 RIOT-OS#4522: avsextrem: linker sometimes doesn't find `bl_init_clks()` RIOT-OS#4560: make: clang is more pedantic than gcc oonf_api is not building with clang. (Partly solved by RIOT-OS#4593) RIOT-OS#4694: drivers/lm75a: does not build RIOT-OS#4737: cortex-m: Hard fault after a thread exits (under some circumstances) RIOT-OS#4822: kw2xrf: packet loss when packets get fragmented RIOT-OS#4876: at86rf2xx: Simultaneous use of different transceiver types is not supported RIOT-OS#4954: chronos: compiling with -O0 breaks RIOT-OS#4866: not all GPIO driver implementations are thread safe: Due to non-atomic operations in the drivers some pin configurations might get lost. RIOT-OS#5009: RIOT is saw-toothing in energy consumption (even when idling) RIOT-OS#5103: xtimer: weird behavior of tests/xtimer_drift: xtimer_drift randomly jumps a few seconds on nrf52 RIOT-OS#5361: cpu/cc26x0: timer broken RIOT-OS#5405: Eratic timings on iotlab-m3 with compression context activated RIOT-OS#5460: cpu/samd21: i2c timing with compiler optimization RIOT-OS#5486: at86rf2xx: lost interrupts RIOT-OS#5489: cpu/lpc11u34: ADC broken RIOT-OS#5603: atmega boards second UART issue RIOT-OS#5678: at86rf2xx: failed assertion in _isr RIOT-OS#5719: cc2538: rf driver doesn't handle large packets RIOT-OS#5799: kw2x: 15.4 duplicate transmits RIOT-OS#5944: msp430: ipv6_hdr unittests fail RIOT-OS#5848: arduino: Race condition in sys/arduino/Makefile.include RIOT-OS#5954: nRF52 uart_write get stuck RIOT-OS#6018: nRF52 gnrc 6lowpan ble memory leak other issues ------------ RIOT-OS#1263: TLSF implementation contains (a) read-before-write error(s). RIOT-OS#3256: make: Setting constants on compile time doesn't really set them everywhere RIOT-OS#3366: periph/i2c: handle NACK RIOT-OS#4488: Making the newlib thread-safe: When calling puts/printf after thread_create(), the CPU hangs for DMA enabled uart drivers.

Hi all,
I've tried to ping a cc2538 based board with the gnrc_networking example:
and all it's ok, but if I try:
I don't receive any answer.
Output of "tcpdump -i wpan0" with correct echo reply:
Output of "tcpdump -i wpan0" without the right echo reply:
With the samr21-xpro I can do:
without problems.
Luca.
