netns_breakns failure with latest LTP sources #823

Open pankajjoshi347 opened 3 years ago

i have tried to run with the latest LTP too but the same error is getting reproduced

attaching complete log of network testcases

all of the following 7 testcases are failing

  1. netns_breakns_ip_ipv4_ioctl
  2. netns_breakns_ns_exec_ipv4_ioctl 3.netns_breakns_ns_exec_ipv6_ioctl
  3. netns_comm_ip_ipv4_ioctl
  4. netns_comm_ip_ipv6_ioctl
  5. netns_comm_ns_exec_ipv4_ioctl
  6. netns_comm_ns_exec_ipv6_ioctl can you suggest how to fix ?

Hi, I am seeing following tests failures with latest LTP source, even after enabling all required kernel configurations.

  1. breakns_ip_ipv4_ioctl fail
  2. breakns_ip_ipv6_ioctl fail
  3. ns_exec_ipv4_ioctl fail
  4. comm_ip_ipv4_ioctl fail
  5. comm_ip_ipv6_ioctl fail
  6. exec_ipv4_ioctl fail
  7. exec_ipv6_ioctl fail

What could be the reason? Am I missing anything?

Thanks

No idea, test your IPv6 setup.

Ankita-020696 commented 3 years ago

No idea, test your IPv6 setup.

IPV6 is enabled in linux.

sysctl -a 2>/dev/null | grep disable_ipv6

net.ipv6.conf.all.disable_ipv6 = 0 net.ipv6.conf.default.disable_ipv6 = 0 net.ipv6.conf.eth0.disable_ipv6 = 0 net.ipv6.conf.lo.disable_ipv6 = 0 net.ipv6.conf.sit0.disable_ipv6 = 0

Any other way to check?

pevik commented 3 years ago

Actually no idea what could be wrong. @akodanev any idea?

Hi, I was try to debugging this issue using print statement but it could not printing . How to proceed it? can you kindly help me to know the issue what exactly happen in that ? Thank you

pevik commented 2 months ago

Can we close this old ticket? If the problem still persists on the current master branch, you can use TST_NET_RHOST_RUN_DEBUG=1 to debug.
