When a dst_confirm() happens, mark the confirmation as pending in the dst. Then on the next packet out, when we have the neigh in-hand, do the update. This removes the dependency in dst_confirm() of dst's having an attached neigh. While we're here, remove the explicit 'dst' NULL check, all except 2 or 3 call sites ensure it's not NULL. So just fix those cases up. Signed-off-by: NDavid S. Miller <davem@davemloft.net>

xs_udp_data_ready() is operating on received packets, and tries to do a dst_confirm() on the dst attached to the SKB. This isn't right, dst confirmation is for output routes, not input rights. It's for resetting the timers on the nexthop neighbour entry for the route, indicating that we've got good evidence that we've successfully reached it. Signed-off-by: NDavid S.

The "bat_" prefix in the source files implementing the batman-adv sysfs and debugfs interface doesn't have a special meaning and are only used by these files and files that implement the actual B.A.T.M.A.N. path finding algorithm. The prefix is better suited to mark files that are used to implement the main part of the path finding. All other files should not use it and therefore gets renamed.

This patch adds a hook in the binding path of netlink. This is used by ctnetlink to allow module autoloading for the case in which one user executes: conntrack -E So far, this resulted in nfnetlink loaded, but not nf_conntrack_netlink. I have received in the past many complains on this behaviour. Signed-off-by: NPablo Neira Ayuso <pablo@netfilter.org> Signed-off-by: NDavid S. Miller <davem@davemloft.net>

This patch adds the following structure: struct netlink_kernel_cfg { unsigned int groups; void (*input)(struct sk_buff *skb); struct mutex *cb_mutex; }; That can be passed to netlink_kernel_create to set optional configurations for netlink kernel sockets. I've populated this structure by looking for NULL and zero parameters at the existing code. The remaining parameters that always need to be set are still left in the original interface. That includes optional parameters for the netlink socket creation. This allows easy extensibility of this interface in the future. This patch also adapts all callers to use this new interface.

If rpfilter is off (or the SKB has an IPSEC path) and there are not tclassid users, we don't have to do anything at all when fib_validate_source() is invoked besides setting the itag to zero. We monitor tclassid uses with a counter (modified only under RTNL and marked __read_mostly) and we protect the fib_validate_source() real work with a test against this counter and whether rpfilter is to be done. Having a way to know whether we need no tclassid processing or not also opens the door for future optimized rpfilter algorithms that do not perform full FIB lookups. Signed-off-by: NDavid S.

At Facebook, we do Layer-3 DSR via IP-in-IP tunneling. Our load balancers wrap an extra IP header on incoming packets so they can be routed to the backend. In the v4 tunnel driver, when these packets fall on the default tunl0 device, the behavior is to decapsulate them and drop them back on the stack. So our setup is that tunl0 has the VIP and eth0 has (obviously) the backend's real address. In IPv6 we do the same thing, but the v6 tunnel driver didn't have this same behavior - if you didn't have an explicit tunnel setup, it would drop the packet. This patch brings that v4 feature to the v6 driver. The same IPv6 address checks are performed as with any normal tunnel, but as the fallback tunnel endpoint addresses are unspecified, the checks must be performed on a per-packet basis, rather than at tunnel configuration time.

Based upon feedback from Julian Anastasov. 1) Use route flags to determine multicast/broadcast, not the packet flags. 2) Leave saddr unspecified in flow key. 3) Adjust how we invoke inet_select_addr(). Pass ip_hdr(skb)->saddr as second arg, and if it was zeronet use link scope. 4) Use loopback as input interface in flow key. Signed-off-by: NDavid S. Miller <davem@davemloft.net>

由 Neal Cardwell 提交于
The code in tcp_v6_conn_request() was implicitly assuming that tcp_v6_send_synack() would take care of dst_release(), much as tcp_v4_send_synack() already does. This resulted in tcp_v6_conn_request() leaking a dst if sysctl_tw_recycle is enabled. This commit restructures tcp_v6_send_synack() so that it accepts a dst pointer and takes care of releasing the dst that is passed in, to plug the leak and avoid future surprises by bringing the IPv6 behavior in line with the IPv4 side.

With the recent change (earlier in this patch series) to set flowi6_oif to treq->iif in inet6_csk_route_req(), the dst lookup in these two functions is now identical, so tcp_v6_send_synack() can now just call inet6_csk_route_req(), to reduce code duplication and keep things closer to the IPv4 side, which is structured this way.
