| Subject: hsr: set .netnsok flag |
| |
| From: Taehee Yoo <ap420073@gmail.com> |
| |
| [ Upstream commit 09e91dbea0aa32be02d8877bd50490813de56b9a ] |
| |
| The hsr module has been supporting the list and status command. |
| (HSR_C_GET_NODE_LIST and HSR_C_GET_NODE_STATUS) |
| These commands send node information to the user-space via generic netlink. |
| But, in the non-init_net namespace, these commands are not allowed |
| because .netnsok flag is false. |
| So, there is no way to get node information in the non-init_net namespace. |
| |
| Fixes: f421436a591d ("net/hsr: Add support for the High-availability Seamless Redundancy protocol (HSRv0)") |
