This file implements the on-demand Hybrid Wireless Mesh Protocol, at this moment using hop-count as the metric. When no mesh path exists for a given destination or the mesh path is not active, frames addressed to that destination will be queued and a Path Request frame will be sent. Queued frames will be sent when the path is resolved (usually after reception of a Path Response) or discarded if discovery times out. Path Requests will also be sent to refresh paths that are being used and are close to expiring. Path Errors are sent when a path discovery process triggered by the attempt to forward a frame originated in a different mesh point times out. Path Errors are also sent when a peer link is determined to be unreachable because of high error rates. Multiple destination support in Path Requests and Path Errors and precursors have not been implemented yet.

The mesh path table associates destinations with the next hop to reach them. The table is a hash of linked lists protected by rcu mechanisms. Every mesh path contains a lock to protect the mesh path state. Each outgoing mesh frame requires a look up into this table. Therefore, the table it has been designed so it is not necessary to hold any lock to find the appropriate next hop. If the path is determined to be active within a rcu context we can safely dereference mpath->next_hop->addr, since it holds a reference to the sta next_hop. After a mesh path has been set active for the first time it next_hop must always point to a valid sta. If this is not possible the mpath must be deleted or replaced in a RCU safe fashion.

The two important features coded in mesh.c are: Recently Multicast Cache: in on-demand HWMP, multicast traffic is retransmitted by every receiving node. Even though a mesh TTL counter avoids infinite loops, it is also necessary to avoid traffic explosion by keeping a cache of multicast mesh frame that have been received recently. With this feature, maximum number of retransmissions of a multicast frame for the case of N nodes within the range of each other would be N. Without it, the maximum number of retransmissions would be in the order of N^(MESH_TTL - 1). Code to support mesh tables.

All the infrastructure to propagate the network namespace information is ready. Make use of it. There is a special case here between the initial network namespace and the other namespaces: * When ipv6 is initialized at boot time (aka in the init_net), it registers to the notifier callback. So addrconf_notify will be called as many time as there are network devices setup on the system and the function will add ipv6 addresses to the network devices. But the first device which needs to have its ipv6 address setup is the loopback, unfortunatly this is not the case. So the loopback address is setup manually in the ipv6 init function. * With the network namespace, this ordering problem does not appears because notifier is already setup and active, so as soon as we register the loopback the ipv6 address is setup and it will be the first device.

由 Stephen Hemminger 提交于
From: Stephen Hemminger <shemminger@linux-foundation.org> Based upon a patch by Marcel Wappler: This patch fixes a DHCP issue of the kernel: some DHCP servers (i.e. in the Linksys WRT54Gv5) are very strict about the contents of the DHCPDISCOVER packet they receive from clients. Table 5 in RFC2131 page 36 requests the fields 'ciaddr' and 'siaddr' MUST be set to '0'. These DHCP servers ignore Linux kernel's DHCP discovery packets with these two fields set to '255.255.255.255' (in contrast to popular DHCP clients, such as 'dhclient' or 'udhcpc'). This leads to a not booting system. Signed-off-by: NDavid S. Miller <davem@davemloft.net>

Merge rate_control_pid_shift_adjust() to rate_control_pid_adjust_rate() in order to make the learning algorithm aware of constraints on rates. Also add some comments and rename variables. This fixes a bug which prevented 802.11b/g non-AP STAs from working with 802.11b only AP STAs. This patch was originally destined for 2.6.26, and is being backported to fix a user reported problem in post-2.6.24 kernels.

We have updated CUBIC to fix some issues with slow increase in large BDP networks. We also improved its convergence speed. The fix is in fact very simple -- the window increase limit of smax during the window probing phase (i.e., convex growth phase) is removed. We found that this does not affect TCP friendliness, but only improves its scalability. We have run some tests in our lab and also over the Internet path from NCSU to Japan. These results can be seen from the following page: http://netsrv.csc.ncsu.edu/wiki/index.php/Intra_protocol_fairness_testing_with_linux-2.6.23.9 http://netsrv.csc.ncsu.edu/wiki/index.php/RTT_fairness_testing_with_linux-2.6.23.9 http://netsrv.csc.ncsu.edu/wiki/index.php/TCP_friendliness_testing_with_linux-2.6.23.9Signed-off-by: NSangtae Ha <sha2@ncsu.edu> Signed-off-by: NStephen Hemminger <shemminger@vyatta.com> Signed-off-by: NDavid S.
