2012-07-11tcp: Fix out of bounds access to tcpm_valsAlexander Duyck
The recent patch "tcp: Maintain dynamic metrics in local cache." introduced an out of bounds access due to what appears to be a typo. I believe this change should resolve the issue by replacing the access to RTAX_CWND with TCP_METRIC_CWND. Signed-off-by: Alexander Duyck <alexander.h.duyck@intel.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2012-07-11mac80211: Fix the Problem of Unreachable Mesh STA from DSChun-Yeow Yeoh
This patch fixes the problem of unreachable mesh STA from Distribution System (DS) due to the introduction of previous patch solving the mesh STA joining from one MBSS to another MBSS.

To help debugging printed hex object use standard bluetooth specifiers in hci_event. The patch changes format from 0x%04x to 0x%4.4x; print manufacturer id and handle in hex instead of int; print opcode always in 0x%4.4x format; status in 0x%2.2x.

2012-07-10net: Fix memory leak - vlan_info structAmir Hanania
In driver reload test there is a memory leak. The structure vlan_info was not freed when the driver was removed. It was not released since the nr_vids var is one after last vlan was removed. The nr_vids is one, since vlan zero is added to the interface when the interface is being set, but the vlan zero is not deleted at unregister. Fix - delete vlan zero when we unregister the device.

2012-07-10ipv4: Calling ->cow_metrics() now is a bug.David S. Miller
Nothing every writes to ipv4 metrics any longer. PMTU is stored in rt->rt_pmtu. Dynamic TCP metrics are stored in a special TCP metrics cache, completely outside of the routes. Therefore ->cow_metrics() can simply nothing more than a WARN_ON trigger so we can catch anyone who tries to add new writes to ipv4 route metrics. Signed-off-by: David S. Miller <davem@davemloft.net>

2012-07-10net: Don't report route RTT metric value in cache dumps.David S. Miller
We don't maintain it dynamically any longer, so reporting it would be extremely misleading. Report zero instead. Signed-off-by: David S. Miller <davem@davemloft.net>
2012-07-10tcp: Maintain dynamic metrics in local cache.David S. Miller
Maintain a local hash table of TCP dynamic metrics blobs. Computed TCP metrics are no longer maintained in the route metrics. The table uses RCU and an extremely simple hash so that it has low latency and low overhead. A simple hash is legitimate because we only make metrics blobs for fully established connections. Some tweaking of the default hash table sizes, metric timeouts, and the hash chain length limit certainly could use some tweaking. But the basic design seems sound.

2012-07-09net/rxrpc/ar-peer.c: remove invalid reference to list iterator variableJulia Lawall
If list_for_each_entry, etc complete a traversal of the list, the iterator variable ends up pointing to an address at an offset from the list head, and not a meaningful structure. Thus this value should not be used after the end of the iterator. This seems to be a copy-paste bug from a previous debugging message, and so the meaningless value is just deleted.

2012-07-09NFC: LLCP late bindingSamuel Ortiz
With the LLCP 16 local SAPs we can potentially quickly run out of source SAPs for non well known services. With the so called late binding we will reserve an SAP only when we actually get a client connection for a local service.
