SEGFAULT/11 on aarch64 about ntopng HOT 10 CLOSED

Hi @djstarfox could you please provide your ntopng configuration file?

from ntopng.

Sure, I should have posted that earlier.... Here are all the non-comments from the ntopng.conf file:

-G=/var/run/ntopng.pid
-i=eth1
-i=syslog://192.168.30.13:514@udp
-w=80
-m="169.254.0.0/16,192.168.1.0/24" #IPranges redacted
-n=0
-d=/opt/ntopng
-p=/etc/ntopng/protos.txt
-v=6

from ntopng.

@djstarfox I suggest to run a couple of tests, running ntopng with eth1 only, and with syslog only, to figure out which interface is leading to the segfault. After that we probably need to send you a binary with debug enabled.

from ntopng.

No luck. Commenting out either (or both) interfaces results in the same crash and segfault. Even after completely purging the working directory (RRD info), it crashes with:

free(): invalid pointer
Aborted

To test from the command line:
cd /usr/share/ntopng/
/usr/bin/ntopng /etc/ntopng/ntopng.conf

from ntopng.

Also, FYI, I've had to downgrade to ntopng_6.1.240428-23337 as a workaround. So, this bug came between version 6.1.240428 and 6.1.240512.

@djstarfox there is a new ntopng_6.1.240621-23628 package available at https://packages.ntop.org/RaspberryPI/bullseye_pi/arm64/ntopng/
It seems to be working fine in our lab, with no crash, please check it and let us know

from ntopng.

After updating to 6.1.240621, ntopng crashes again after a minute with:
free(): invalid size
Aborted

from ntopng.

@djstarfox please drop an email to cardigliano at ntop.org, I will send you a binary with debug support

from ntopng.

I'm testing patch included with ntopng_6.1.240628-23672. Will let you know how it goes.

from ntopng.

Been running on the new version all weekend without any crashes. OK to resolve, unless someone else also wants to test.
