| 6 | Description: SO_REUSEPORT may not exist in running kernel |
| 7 | When userspace defines SO_REUSEPORT we will attempt to enable socket |
| 8 | port number reuse. However if the running kernel does not support |
| 9 | this call it will fail preventing daemon startup. If this call is |
| 10 | present but fails ENOPROTOOPT then we know that actually the kernel |
| 11 | does not support it and we should continue as if we did not have the |
| 12 | call at all. (LP: #1228204) |
| 13 | . |
| 14 | This patch could be removed from the debian package after jessie release. |
