native: gnrc: hardcore pinging crashes #3824
Comments
When I use ping6 with a payload 1024 it just times out. Does it really crash for you?
|
@cgundogan, yes, if you merge #3826. |
I was missing that piece of info in the description ;)
|
Looked similar here. |
I still get crasches so yes. But the
Looks more or less like normal packet data to me, so I would safely assume that it is not a packet buffer problem. [edit: accidentally posted the wrong output] |
But the crashes look awefully similar to the ones in #3341. Are you sure this issue isn't a duplicate? |
No, but I cannot check because I cannot even ping native from Linux on master. |
sudo ping6 -f -I tap0 fe80::3c0f:6ff:fed0:6188 is not working? |
Yes, only if I revert #3931 Edit: Sorry verb was missing. |
(the IPv6 address being native's IPv6 address) |
what? There should be no 6Lo-ND on native.... |
Yes, but with #3931 it wouldn't reply to NBR SOL anymore. |
yes, because |
We'll probably not fix this for this release, so I'll retag. |
Cannot reproduce any more. |
So can we close? |
(me neither btw) |
Tested on two machines several times. Haven't seen a single crash -> close. |
(to be fair: two very similar machines, but maybe someone with an Ubuntu PC that isn't a ThinkPad likes to test too ^^) |
I mean I tested on two machines (Lenovo Thinkpad X220 with Intel(R) Core(TM) i5-2520M CPU @ 2.50GHz and Dell Desktop machine with Intel(R) Core(TM) i7-3770 CPU @ 3.40GHz). But yes, both machines running Arch Linux with Linux 4.6.3. |
Tested on a Intel(R) Core(TM) i7-2600 CPU @ 3.40GHz with Debian and Linux 4.4.0-1-amd64, too. Works also without problems. |
Ah I thought you were refering to our two machines :-) |
did you try multiple parallel 'ping -f'? -----Original Message----- Cannot reproduce any more. You are receiving this because you were assigned. |
Yes. Different issue. |
Sending 1.000.000 pings between two native instances in gnrc_networking example with a payload of 1024 bytes and a delay of 0 crashes the sending node after several 100.000 pings. Reducing the payload to something smaller (e.g. 512 bytes) works fine.
