To solve the issue, a self interrupt IPI is used to trigger the soft_irq earlier. This all is just gross hackery,... 24 Jun 2010 03:08

When we have multiple transformations for a xfrm policy, the bundle instance will be a chain of bundles with only the first one having the policy reference. When policy_genid is bumped it will expire the first bundle in the chain which is equivalen... 24 Jun 2010 02:03
