Hi, youtube-dl hangs trying to download videos from youtube. The commit below is my regression test result. Disabling ipv6 indeed does fix this for me.
Jan --- d4ead6b34b67fd711639324b6465a050bcb197d4 is the first bad commit commit d4ead6b34b67fd711639324b6465a050bcb197d4 Author: David Ahern <dsah...@gmail.com> Date: Tue Apr 17 17:33:16 2018 -0700 net/ipv6: move metrics from dst to rt6_info Similar to IPv4, add fib metrics to the fib struct, which at the moment is rt6_info. Will be moved to fib6_info in a later patch. Copy metrics into dst by reference using refcount. To make the transition: - add dst_metrics to rt6_info. Default to dst_default_metrics if no metrics are passed during route add. No need for a separate pmtu entry; it can reference the MTU slot in fib6_metrics - ip6_convert_metrics allocates memory in the FIB entry and uses ip_metrics_convert to copy from netlink attribute to metrics entry - the convert metrics call is done in ip6_route_info_create simplifying the route add path + fib6_commit_metrics and fib6_copy_metrics and the temporary mx6_config are no longer needed - add fib6_metric_set helper to change the value of a metric in the fib entry since dst_metric_set can no longer be used - cow_metrics for IPv6 can drop to dst_cow_metrics_generic - rt6_dst_from_metrics_check is no longer needed - rt6_fill_node needs the FIB entry and dst as separate arguments to keep compatibility with existing output. Current dst address is renamed to dest. (to be consistent with IPv4 rt6_fill_node really should be split into 2 functions similar to fib_dump_info and rt_fill_info) - rt6_fill_node no longer needs the temporary metrics variable Signed-off-by: David Ahern <dsah...@gmail.com> Signed-off-by: David S.
