* mac80211: add missing "break" statement in mesh codeJohannes Berg2008-03-061-0/+1
| | | | | | | | | | | This inserts a missing break statement which, if hit, would cause the code to fall-through and unlock a spinlock twice. Noticed via sparse's "lock count wrong in basic block" warning and careful code inspection.

* mac80211: code for on-demand Hybrid Wireless Mesh ProtocolLuis Carlos Cobo2008-03-061-0/+862
| | | | | | | | | | | | | | | | | | | | | | 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.

* mac80211: mesh path table implementationLuis Carlos Cobo2008-03-061-0/+522
| | | | | | | | | | | | | | | | | | | | 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.

* mac80211: support functions for meshLuis Carlos Cobo2008-03-061-0/+383
| | | | | | | | | | | | | | | | | | 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.

| * [IPCONFIG]: The kernel gets no IP from some DHCP serversStephen Hemminger2008-03-041-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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: David S. Miller <davem@davemloft.net>
