I've figured out what happened, and it's my fault only :( I have modified your patchset and added --shared-mem option. And forgot to specify it to gdb :) Without it memory is not shared, and rte_memseg_info_get() returned fd = -1. And if you put it into control message for sendmsg(), you get your -EBADF. So please ignore this. But, nevertheless, ovs in container still dies with: --- cut --- Program received signal SIGSEGV, Segmentation fault.
