| Subject: xfrm: Release dst if this dst is improper for vti tunnel |
| |
| From: "fan.du" <fan.du@windriver.com> |
| |
| [ Upstream commit 236c9f84868534c718b6889aa624de64763281f9 ] |
| |
| After searching rt by the vti tunnel dst/src parameter, |
| if this rt has neither attached to any transformation |
| nor the transformation is not tunnel oriented, this rt |
| should be released back to ip layer. |
| |
| otherwise causing dst memory leakage. |
