Subject: [dpdk-users] IP Reassembly with more 4 packets crash
Date: Tue, 13 Aug 2019 08:37:09 +0530 [thread overview]
Message-ID: <CANDhLBanxowMDeyDzhFvbOzazijcm+adWnvTHgyHsZks8MaUfA@mail.gmail.com> (raw)
Hi,
I have looked at previous mails on this mailing list and also elsewhere on
Google and could not find any information related to this.
Whenever I have to reassemble a valid IP packet with more than 4 fragments,
I see a crash. Stack trace below. I assume the number 4 comes
from RTE_LIBRTE_IP_FRAG_MAX_FRAG.
(gdb) bt

Is this a known issue? Are there any workaround?
