Hi,

i am running LTP on kernel 5.10.19 custom kermel with  LTP Version: 20210524-15-gf96b8fe15 but few of network tests are getting failed on my distro.

Following 8 testcases are failing, i have attached strace log for one of them kindly find it

  *   netns_breakns_ip_ipv4_ioctl
  *   netns_breakns_ns_exec_ipv4_ioctl
netns_breakns_ns_exec_ipv6_ioctl
  *   netns_comm_ip_ipv4_ioctl
  *   netns_comm_ip_ipv6_ioctl
  *   netns_comm_ns_exec_ipv4_ioctl
  *   netns_comm_ns_exec_ipv6_ioctl

Also attaching the network config

Can you suggest what's going wrong with these testcases ? What could be the failure reason ??


Kindly suggest
