Hello all,
I am testing ABF functionality and was able to crash VPP.
I was using v19.04-rc0~458-g53ba544d7. Configured VPP using following commands:
set int state GigabitEthernet86/0/3 up
set int ip address GigabitEthernet86/0/3 xxx.xx.223.14/29
set int ip address GigabitEthernet86/0/3 2001:470:xxxx:xxx::600/64
ip route add 0.0.0.0/0 via xxx.xx.223.9 GigabitEthernet86/0/3
ip route add ::/0 via 2001:470:xxxx:xxx::1 GigabitEthernet86/0/3
set int state GigabitEthernet86/0/2 up
set int ip address GigabitEthernet86/0/2 100.69.1.1/24
set int ip address GigabitEthernet86/0/2 2001:470:yyyy:yyy::1/56
set int ip addr GigabitEthernet86/0/0 192.168.20.1/29
set int state GigabitEthernet86/0/0 up
abf policy add id 0 acl 0 via 192.168.20.2 GigabitEthernet86/0/0
abf attach ip4 policy 0 priority 1 GigabitEthernet86/0/2
Running VPP under gdb, the back trace is:
Thread 1 "vpp_main" received signal SIGABRT, Aborted.
