2009-05-11nl80211 : Add support for configuring MFPJouni Malinen
NL80211_CMD_ASSOCIATE request must be able to indicate whether management frame protection (IEEE 802.11w) is being used. mac80211 was able to use MFP in client mode only with WEXT, but the new NL80211_ATTR_USE_MFP attribute will allow this to be done with nl80211, too. Since we are currently using nl80211 for MFP only with drivers that use user space SME, only MFP disabled and required values are used. However, the NL80211_ATTR_USE_MFP attribute is an enum that can be extended with MFP optional in the future, if that is needed with some drivers (e.g., if the RSN IE is generated by the driver).

wl12xx is a driver for TI wl1251 802.11 chipset designed for embedded devices, supporting both SDIO and SPI busses. Currently the driver supports only SPI. Adding support 1253 (the 5 GHz version) should be relatively easy.

2009-05-05net: introduce a list of device addresses dev_addr_list (v6)Jiri Pirko
v5 -> v6 (current): -removed so far unused static functions -corrected dev_addr_del_multiple to call del instead of add v4 -> v5: -added device address type (suggested by davem) -removed refcounting (better to have simplier code then safe potentially few bytes) v3 -> v4: -changed kzalloc to kmalloc in __hw_addr_add_ii() -ASSERT_RTNL() avoided in dev_addr_flush() and dev_addr_init() v2 -> v3: -removed unnecessary rcu read locking -moved dev_addr_flush() calling to ensure no null dereference of dev_addr v1 -> v2: -added forgotten ASSERT_RTNL to dev_addr_init and dev_addr_flush -removed unnecessary rcu_read locking in dev_addr_init -use compare_ether_addr_64bits instead of compare_ether_addr -use L1_CACHE_BYTES as size for allocating struct netdev_hw_addr -use call_rcu instead of rcu_synchronize -moved is_etherdev_addr into __KERNEL__ ifdef This patch introduces a new list in struct net_device and brings a set of functions to handle the work with device address list. The list is a replacement for the original dev_addr field and because in some situations there is need to carry several device addresses with the net device. To be backward compatible, dev_addr is made to point to the first member of the list so original drivers sees no difference. Signed-off-by: Jiri Pirko <jpirko@redhat.com> Signed-off-by: David S.

2009-05-05netfilter: xt_cluster: fix use of cluster match with 32 nodesPablo Neira Ayuso
This patch fixes a problem when you use 32 nodes in the cluster match: % iptables -I PREROUTING -t mangle -i eth0 -m cluster \ --cluster-total-nodes 32 --cluster-local-node 32 \ --cluster-hash-seed 0xdeadbeef -j MARK --set-mark 0xffff iptables: Invalid argument. Run `dmesg' for more information. % dmesg | tail -1 xt_cluster: this node mask cannot be higher than the total number of nodes The problem is related to this checking: if (info->node_mask >= (1 << info->total_nodes)) { printk(KERN_ERR "xt_cluster: this node mask cannot be " "higher than the total number of nodes\n"); return false; } (1 << 32) is 1. Thus, the checking fails. BTW, I said this before but I insist: I have only tested the cluster match with 2 nodes getting ~45% extra performance in an active-active setup. The maximum limit of 32 nodes is still completely arbitrary. I'd really appreciate if people that have more nodes in their setups let me know.

2009-05-04usbnet: CDC EEM support (v5)Omar Laazimani
This introduces a CDC Ethernet Emulation Model (EEM) host side driver to support USB EEM devices. EEM is different from the Ethernet Control Model (ECM) currently supported by the "CDC Ethernet" driver. One key difference is that it doesn't require of USB interface alternate settings to manage interface state; some maldesigned hardware can't handle that part of USB. It also avoids a separate USB interface for control and status updates.

2009-04-28netfilter: revised locking for x_tablesStephen Hemminger
The x_tables are organized with a table structure and a per-cpu copies of the counters and rules. On older kernels there was a reader/writer lock per table which was a performance bottleneck. In 2.6.30-rc, this was converted to use RCU and the counters/rules which solved the performance problems for do_table but made replacing rules much slower because of the necessary RCU grace period. This version uses a per-cpu set of spinlocks and counters to allow to table processing to proceed without the cache thrashing of a global reader lock and keeps the same performance for table updates.

netif_tx_queue_stopped(txq) is most of the time false. Yet its cost is very expensive on SMP. static inline int netif_tx_queue_stopped(const struct netdev_queue *dev_queue) { return test_bit(__QUEUE_STATE_XOFF, &dev_queue->state); } I saw this on oprofile hunting and bnx2 driver bnx2_tx_int(). We probably should split "struct netdev_queue" in two parts, one being read mostly. __netif_tx_lock() touches _xmit_lock & xmit_lock_owner, these deserve a separate cache line.

2009-04-28net: Avoid extra wakeups of threads blocked in wait_for_packet()Eric Dumazet
In 2.6.25 we added UDP mem accounting. This unfortunatly added a penalty when a frame is transmitted, since we have at TX completion time to call sock_wfree() to perform necessary memory accounting. This calls sock_def_write_space() and utimately scheduler if any thread is waiting on the socket. Thread(s) waiting for an incoming frame was scheduled, then had to sleep again as event was meaningless. (All threads waiting on a socket are using same sk_sleep anchor) This adds lot of extra wakeups and increases latencies, as noted by Christoph Lameter, and slows down softirq handler. Reference : http://marc.info/?l=linux-netdev&m=124060437012283&w=2 Fortunatly, Davide Libenzi recently added concept of keyed wakeups into kernel, and particularly for sockets (see commit 37e5540b3c9d838eb20f2ca8ea2eb8072271e403 epoll keyed wakeups: make sockets use keyed wakeups) Davide goal was to optimize epoll, but this new wakeup infrastructure can help non epoll users as well, if they care to setup an appropriate handler. This patch introduces new DEFINE_WAIT_FUNC() helper and uses it in wait_for_packet(), so that only relevant event can wakeup a thread blocked in this function. Trace of function calls from bnx2 TX completion bnx2_poll_work() is : __kfree_skb() skb_release_head_state() sock_wfree() sock_def_write_space() __wake_up_sync_key() __wake_up_common() receiver_wake_function() : Stops here since thread is waiting for an INPUT Reported-by: Christoph Lameter <cl@linux.com> Signed-off-by: Eric Dumazet <dada1@cosmosbay.com> Signed-off-by: David S.

2009-04-27tun: add IFF_TUN_EXCL flag to avoid opening a persistent device.David Woodhouse
When creating a certain types of VPN, NetworkManager will first attempt to find an available tun device by iterating through 'vpn%d' until it finds one that isn't already busy. Then it'll set that to be persistent and owned by the otherwise unprivileged user that the VPN dæmon itself runs as. There's a race condition here -- during the period where the vpn%d device is created and we're waiting for the VPN dæmon to actually connect and use it, if we try to create _another_ device we could end up re-using the same one -- because trying to open it again doesn't get -EBUSY as it would while it's _actually_ busy. So solve this, we add an IFF_TUN_EXCL flag which causes tun_set_iff() to fail if it would be opening an existing persistent tundevice -- so that we can make sure we're getting an entirely _new_ device.
