net: add confirm_neigh method to dst_ops

2017-02-07T18:07:46+00:00

Add confirm_neigh method to dst_ops and use it from IPv4 and IPv6 to lookup and confirm the neighbour. Its usage via the new helper dst_confirm_neigh() should be restricted to MSG_PROBE users for performance reasons. For XFRM prefer the last tunnel address, if present. With help from Steffen Klassert.

net: remove bh disabling around percpu_counter accesses

2017-01-20T16:27:22+00:00

Shaohua Li made percpu_counter irq safe in commit 098faf5805c8 ("percpu_counter: make APIs irq safe") We can safely remove BH disable/enable sections around various percpu_counter manipulations. Signed-off-by: Eric Dumazet Signed-off-by: David S. Miller

dst: Pass a sk into .local_out

2015-10-08T11:26:55+00:00

For consistency with the other similar methods in the kernel pass a struct sock into the dst_ops .local_out method. Simplifying the socket passing case is needed a prequel to passing a struct net reference into .local_out. Signed-off-by: "Eric W. Biederman" Signed-off-by: David S. Miller

net: Remove protocol from struct dst_ops

2015-03-09T20:06:10+00:00

After my change to neigh_hh_init to obtain the protocol from the neigh_table there are no more users of protocol in struct dst_ops. Remove the protocol field from dst_ops and all of it's initializers. Signed-off-by: "Eric W. Biederman" Signed-off-by: David S. Miller

percpu_counter: add @gfp to percpu_counter_init()

2014-09-08T00:51:29+00:00

Percpu allocator now supports allocation mask. Add @gfp to percpu_counter_init() so that !GFP_KERNEL allocation masks can be used with percpu_counters too. We could have left percpu_counter_init() alone and added percpu_counter_init_gfp(); however, the number of users isn't that high and introducing _gfp variants to all percpu data structures would be quite ugly, so let's just do the conversion. This is the one with the most users. Other percpu data structures are a lot easier to convert. This patch doesn't make any functional difference.

net: Pass optional SKB and SK arguments to dst_ops->{update_pmtu,redirect}()

2012-07-17T10:29:28+00:00

This will be used so that we can compose a full flow key. Even though we have a route in this context, we need more. In the future the routes will be without destination address, source address, etc. keying. One ipv4 route will cover entire subnets, etc. In this environment we have to have a way to possess persistent storage for redirects and PMTU information. This persistent storage will exist in the FIB tables, and that's why we'll need to be able to rebuild a full lookup flow key here. Using that flow key will do a fib_lookup() and create/update the persistent entry. Signed-off-by: David S. Miller

ipv4: Generalize ip_do_redirect() and hook into new dst_ops->redirect.

net: Add optional SKB arg to dst_ops->neigh_lookup().

2012-07-05T08:04:01+00:00

Causes the handler to use the daddr in the ipv4/ipv6 header when the route gateway is unspecified (local subnet). Signed-off-by: David S. Miller
