| Subject: net:dccp: do not report ICMP redirects to user space |
| |
| From: Duan Jiong <duanj.fnst@cn.fujitsu.com> |
| |
| [ Upstream commit bd784a140712fd06674f2240eecfc4ccae421129 ] |
| |
| DCCP shouldn't be setting sk_err on redirects as it |
| isn't an error condition. it should be doing exactly |
| what tcp is doing and leaving the error handler without |
| touching the socket. |
