2011-06-01cfg80211: don't drop p2p probe responsesEliad Peller
Commit 0a35d36 ("cfg80211: Use capability info to detect mesh beacons") assumed that probe response with both ESS and IBSS bits cleared means that the frame was sent by a mesh sta. However, these capabilities are also being used in the p2p_find phase, and the mesh-validation broke it. Rename the WLAN_CAPABILITY_IS_MBSS macro, and verify that mesh ies exist before assuming this frame was sent by a mesh sta. Signed-off-by: Eliad Peller <eliad@wizery.com> Signed-off-by: John W.

2011-05-31ip_options_compile: properly handle unaligned pointerChris Metcalf
The current code takes an unaligned pointer and does htonl() on it to make it big-endian, then does a memcpy(). The problem is that the compiler decides that since the pointer is to a __be32, it is legal to optimize the copy into a processor word store. However, on an architecture that does not handled unaligned writes in kernel space, this produces an unaligned exception fault. The solution is to track the pointer as a "char *" (which removes a bunch of unpleasant casts in any case), and then just use put_unaligned_be32() to write the value to memory.

2011-05-30batman-adv: Ensure that we really have route changes in update_routeSven Eckelmann
The debug output of update_route has tests for "route deleted" and "route added". All other situations are handled as "route changed".

2011-05-27SUNRPC: Support for RPC over AF_LOCAL transportsChuck Lever
TI-RPC introduces the capability of performing RPC over AF_LOCAL sockets. It uses this mainly for registering and unregistering local RPC services securely with the local rpcbind, but we could also conceivably use it as a generic upcall mechanism. This patch provides a client-side only implementation for the moment. We might also consider a server-side implementation to provide AF_LOCAL access to NLM (for statd downcalls, and such like). Autobinding is not supported on kernel AF_LOCAL transports at this time. Kernel ULPs must specify the pathname of the remote endpoint when an AF_LOCAL transport is created. rpcbind supports registering services available via AF_LOCAL, so the kernel could handle it with some adjustment to ->rpcbind and ->set_port. But we don't need this feature for doing upcalls via well-known named sockets. This has not been tested with ULPs that move a substantial amount of data. Thus, I can't attest to how robust the write_space and congestion management logic is. Signed-off-by: Chuck Lever <chuck.lever@oracle.com> Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>

2011-05-27SUNRPC: Use AF_LOCAL for rpcbind upcallsChuck Lever
As libtirpc does in user space, have our registration API try using an AF_LOCAL transport first when registering and unregistering. This means we don't chew up privileged ports, and our registration is bound to an "owner" (the effective uid of the process on the sending end of the transport). Only that "owner" may unregister the service. The kernel could probe rpcbind via an rpcbind query to determine whether rpcbind has an AF_LOCAL service. For simplicity, we use the same technique that libtirpc uses: simply fail over to network loopback if creating an AF_LOCAL transport to the well-known rpcbind service socket fails. This means we open-code the pathname of the rpcbind socket in the kernel. For now we have to do that anyway because the kernel's RPC over AF_LOCAL implementation does not support autobind. That may be undesirable in the long term. Signed-off-by: Chuck Lever <chuck.lever@oracle.com> Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>

2011-05-27SUNRPC: Rename xs_encode_tcp_fragment_header()Chuck Lever

Also, move it to a place where it is more easily shared amongst the various send_request methods. And finally, replace the "htonl" macro invocation with its modern equivalent.

2011-05-27inetpeer: fix race in unused_list manipulationsEric Dumazet
Several crashes in cleanup_once() were reported in recent kernels. Commit d6cc1d642de9 (inetpeer: various changes) added a race in unlink_from_unused(). One way to avoid taking unused_peers.lock before doing the list_empty() test is to catch 0->1 refcnt transitions, using full barrier atomic operations variants (atomic_cmpxchg() and atomic_inc_return()) instead of previous atomic_inc() and atomic_add_unless() variants. We then call unlink_from_unused() only for the owner of the 0->1 transition. Add a new atomic_add_unless_return() static helper With help from Arun Sharma.
