2008-07-05ipv4: remove static flush_delay variableDenis V. Lunev
flush delay is used as an external storage for net.ipv4.route.flush sysctl entry. It is write-only. The ctl_table->data for this entry is used once. Fix this case to point to the stack to remove global variable. Do this to avoid additional variable on struct net in the next patch. Possible race (as it was before) accessing this local variable is removed using flush_mutex. Signed-off-by: Denis V. Lunev <den@openvz.org> Signed-off-by: David S. Miller <davem@davemloft.net>

2008-07-03svcrpc: fix handling of garbage argsJ. Bruce Fields
To return garbage_args, the accept_stat must be 0, and we must have a verifier. So we shouldn't be resetting the write pointer as we reject the call. Also, we must add the two placeholder words here regardless of success of the unwrap, to ensure the output buffer is left in a consistent state for svcauth_gss_release(). This fixes a BUG() in svcauth_gss.c:svcauth_gss_release(). Thanks to Aime Le Rouzic for bug report, debugging help, and testing. Signed-off-by: J.

2008-07-03bridge: fix use-after-free in br_cleanup_bridges()Patrick McHardy
Unregistering a bridge device may cause virtual devices stacked on the bridge, like vlan or macvlan devices, to be unregistered as well. br_cleanup_bridges() uses for_each_netdev_safe() to iterate over all devices during cleanup. This is not enough however, if one of the additionally unregistered devices is next in the list to the bridge device, it will get freed as well and the iteration continues on the freed element. Restart iteration after each bridge device removal from the beginning to fix this, similar to what rtnl_link_unregister() does.

2008-07-03tcp: de-bloat a bit with factoring NET_INC_STATS_BH outPavel Emelyanov
There are some places in TCP that select one MIB index to bump snmp statistics like this: if (<something>) NET_INC_STATS_BH(<some_id>); else if (<something_else>) NET_INC_STATS_BH(<some_other_id>); ... else NET_INC_STATS_BH(<default_id>); or in a more tricky but still similar way. On the other hand, this NET_INC_STATS_BH is a camouflaged increment of percpu variable, which is not that small. Factoring those cases out de-bloats 235 bytes on non-preemptible i386 config and drives parts of the code into 80 columns. add/remove: 0/0 grow/shrink: 0/7 up/down: 0/-235 (-235) function old new delta tcp_fastretrans_alert 1437 1424 -13 tcp_dsack_set 137 124 -13 tcp_xmit_retransmit_queue 690 676 -14 tcp_try_undo_recovery 283 265 -18 tcp_sacktag_write_queue 1550 1515 -35 tcp_update_reordering 162 106 -56 tcp_retransmit_timer 990 904 -86 Signed-off-by: Pavel Emelyanov <xemul@openvz.org> Signed-off-by: David S.

2008-07-02svcrdma: Change WR context get/put to use the kmem cacheTom Tucker
Change the WR context pool to be shared across mount points. This reduces the RDMA transport memory footprint significantly since idle mounts don't consume WR context memory. Signed-off-by: Tom Tucker <tom@opengridcomputing.com>
2008-07-02svcrdma: Create a kmem cache for the WR contextsTom Tucker

2008-07-02svcrdma: Add flush_scheduled_work to module exit functionTom Tucker
Make certain all transports pending free are flushed from the wq before unloading the module. Signed-off-by: Tom Tucker <tom@opengridcomputing.com>
2008-07-02svcrdma: Limit ORD based on client's advertised IRDTom Tucker
When adapters have differing IRD limits, the RDMA transport will fail to connect properly. The RDMA transport should use the client's advertised inbound read limit when computing its outbound read limit. For iWARP transports, there is currently no standard for exchanging IRD/ORD during connection establishment so the 'responder_resources' field in the connect event is the local device's limit. The RDMA transport can be configured to use a smaller ORD by writing the desired number to the /proc/sys/sunrpc/svc_rdma/max_outbound_read_requests file. Signed-off-by: Tom Tucker <tom@opengridcomputing.com>
2008-07-02svcrdma: Remove unneeded spin locks from __svc_rdma_freeTom Tucker
At the time __svc_rdma_free is called, we are guaranteed that all references to this transport are gone. There is, therefore, no need to protect the resource lists with a spin lock. Signed-off-by: Tom Tucker <tom@opengridcomputing.com>

2008-07-02svcrdma: Move the DMA unmap logic to the CQ handlerTom Tucker
Separate DMA unmap from context destruction and perform DMA unmapping in the SQ/RQ CQ reap functions. This is necessary to support software based RDMA implementations that actually copy the data in their ib_dma_unmap callback functions and architectures that don't have cache coherent I/O busses. Signed-off-by: Tom Tucker <tom@opengridcomputing.com>
2008-07-02svcrdma: Use reply and chunk map for RDMA_READ processingTom Tucker
Modify the RDMA_READ processing to use the reply and chunk list mapping data types. Also add a special purpose 'hdr_count' field in in the context to hold the header page count instead of overloading the SGE length field and corrupting the DMA map length. Signed-off-by: Tom Tucker <tom@opengridcomputing.com>
2008-07-02svcrdma: Use RPC reply map for RDMA_WRITE processingTom Tucker
Use the new svc_rdma_req_map data type for mapping the client side memory to the server side memory. Move the DMA mapping to the context pointed to by each WR individually so that it is unmapped after the WR completes. Signed-off-by: Tom Tucker <tom@opengridcomputing.com>

2008-07-02mac80211: rework debug settings and make debugging saferJohannes Berg
This patch reworks the mac80211 debug settings making them more focused and adding help text for those that didn't have one. It also removes a number of printks that can be triggered remotely and add no value, e.g. "too short deauthentication frame received - ignoring".

2008-06-30build algorithms into the mac80211 moduleAdrian Bunk
The old infrastructure was: - the default algorithm is built into mac80211 - other algorithms get into their own modules The implementation of this complicated scheme was horrible (just look at net/mac80211/Makefile), and anyone adding a new algorithm would most likely not get it right at his first attempt. This patch therefore builds all enabled algorithms into the mac80211 module. The user interface for the rate control algorithms changes as follows: - first the user can choose which algorithms to enable (currently only MAC80211_RC_PID is available) - if more than one algorithm is enabled (currently not possible since only one algorithm is present) the user then chooses the default one Note: - MAC80211_RC_PID is always enables for CONFIG_EMBEDDED=n Technical changes: - all selected algorithms get into the mac80211 module - net/mac80211/Makefile can now become much less complicated - support for rc80211_pid_algo.c being modular is no longer required - this includes unexporting mesh_plink_broken Signed-off-by: Adrian Bunk <bunk@kernel.org> Signed-off-by: John W.
