* virtio_net: Cleanup command queue scatterlist usageAlex Williamson2009-05-011-6/+10
| | | | | | | | | | We were avoiding calling sg_init* on scatterlists passed into virtnet_send_command to prevent extraneous end markers. This caused build warnings for uninitialized variables.

* smsc95xx: add support for LAN9512 and LAN9514Steve Glendinning2009-05-011-0/+5
| | | | | | | | | | | | LAN9512 and LAN9514 are USB hubs with an integrated 10/100 ethernet controller. Logically this looks like an ethernet controller (similar to LAN9500) permanently attached to one of the hub's downstream ports. This patch adds the usb device id of the new ethernet controller to the smsc95xx driver. This id is the same in both new devices.

* netconsole: take care of NETDEV_UNREGISTER eventBruno Prémont2009-05-011-1/+10
| | | | | | | | | | | | | | | | | | When netconsole is loaded and a network interface fades away (e.g. on rmmod $interface_driver_module) the rmmod remains stuck and some locks are taken that prevent any additional module loading/unloading as well as interface up/down changes. In addition kernel logs (and console) get flooded at 10s interval with [ 122.464065] unregister_netdevice: waiting for eth0 to become free. Usage count = 1 [ 132.704059] unregister_netdevice: waiting for eth0 to become free. Usage count = 1 This patch lets netconsole take NETDEV_UNREGISTER event into account and release the affected interface if it was in use.

| | | | | | | | | | | | | | | When skb_rx_queue_recorded() is true, we dont want to use jash distribution as the device driver exactly told us which queue was selected at RX time. jhash makes a statistical shuffle, but this wont work with 8 static inputs. Later improvements would be to compute reciprocal value of real_num_tx_queues to avoid a divide here. But this computation should be done once, when real_num_tx_queues is set.

* mv643xx_eth: 64bit mib counter read fixLennert Buytenhek2009-04-291-2/+0
| | | | | | | | | | | | | | | | | | On several mv643xx_eth hardware versions, the two 64bit mib counters for 'good octets received' and 'good octets sent' are actually 32bit counters, and reading from the upper half of the register has the same effect as reading from the lower half of the register: an atomic read-and-clear of the entire 32bit counter value. This can under heavy traffic occasionally lead to small numbers being added to the upper half of the 64bit mib counter even though no 32bit wrap has occured. Since we poll the mib counters at least every 30 seconds anyway, we might as well just skip the reads of the upper halves of the hardware counters without breaking the stats, which this patch does.

* mv643xx_eth: OOM handling fixesLennert Buytenhek2009-04-291-9/+13
| | | | | | | | | | | | | | | | | | | | | | | | Currently, when OOM occurs during rx ring refill, mv643xx_eth will get into an infinite loop, due to the refill function setting the OOM bit but not clearing the 'rx refill needed' bit for this queue, while the calling function (the NAPI poll handler) will call the refill function in a loop until the 'rx refill needed' bit goes off, without checking the OOM bit. This patch fixes this by checking the OOM bit in the NAPI poll handler before attempting to do rx refill. This means that once OOM occurs, we won't try to do any memory allocations again until the next invocation of the poll handler. While we're at it, change the OOM flag to be a single bit instead of one bit per receive queue since OOM is a system state rather than a per-queue state, and cancel the OOM timer on entry to the NAPI poll handler if it's running to prevent it from firing when we've already come out of OOM.

* | e100: do not go D3 in shutdown unless system is powering offThadeu Lima de Souza Cascardo2009-04-281-7/+23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | After experimenting with kexec with the last merges after 2.6.29, I've had some problems when probing e100. It would not read the eeprom. After some bisects, I realized this has been like that since forever (at least 2.6.18). The problem is that shutdown is doing the same thing that suspend does and puts the device in D3 state. I couldn't find a way to get the device back to a sane state in the probe function. So, based on some similar patches from Rafael J. Wysocki for e1000, e1000e, and ixgbe, I wrote this one for e100.

| * | Bluetooth: Fix connection establishment with low security requirementMarcel Holtmann2009-04-281-6/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Bluetooth 2.1 specification introduced four different security modes that can be mapped using Legacy Pairing and Simple Pairing. With the usage of Simple Pairing it is required that all connections (except the ones for SDP) are encrypted. So even the low security requirement mandates an encrypted connection when using Simple Pairing. When using Legacy Pairing (for Bluetooth 2.0 devices and older) this is not required since it causes interoperability issues. To support this properly the low security requirement translates into different host controller transactions depending if Simple Pairing is supported or not. However in case of Simple Pairing the command to switch on encryption after a successful authentication is not triggered for the low security mode. This patch fixes this and actually makes the logic to differentiate between Simple Pairing and Legacy Pairing a lot simpler.

| * | Bluetooth: Add different pairing timeout for Legacy PairingMarcel Holtmann2009-04-284-3/+40

The problem part is the dedicated pairing when using Legacy Pairing (Bluetooth 2.0 and before). At that point no user is present and pairing attempts will be disconnected within 10 seconds or less. In previous kernel version this was not a problem since the disconnect timeout wasn't triggered on incoming connections for the first time. However this caused issues with broken host stacks that kept the connections around after dedicated pairing. When the support for Simple Pairing got added, the link establishment procedure needed to be changed and now causes issues when using Legacy Pairing When using Simple Pairing it is possible to do a proper reference counting of ACL link users. With Legacy Pairing this is not possible since the specification is unclear in some areas and too many broken Bluetooth devices have already been deployed. So instead of trying to deal with all the broken devices, a special pairing timeout will be introduced that increases the timeout to 60 seconds when pairing is triggered. If a broken devices now puts the stack into an unforeseen state, the worst that happens is the disconnect timeout triggers after 120 seconds instead of 4 seconds. This allows successful pairings with legacy and broken devices now. Based on a report by Johan Hedberg <johan.hedberg@nokia.com> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>

|/ | | | | | | | | | | | | | | | | 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.

* net: Avoid extra wakeups of threads blocked in wait_for_packet()Eric Dumazet2009-04-282-3/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* ipv4: Limit size of route cache hash tableAnton Blanchard2009-04-271-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | Right now we have no upper limit on the size of the route cache hash table. On a 128GB POWER6 box it ends up as 32MB: IP route cache hash table entries: 4194304 (order: 9, 33554432 bytes) It would be nice to cap this for memory consumption reasons, but a massive hashtable also causes a significant spike when measuring OS jitter. With a 32MB hashtable and 4 million entries, rt_worker_func is taking 5 ms to complete. On another system with more memory it's taking 14 ms. Even though rt_worker_func does call cond_sched() to limit its impact, in an HPC environment we want to keep all sources of OS jitter to a minimum. With the patch applied we limit the number of entries to 512k which can still be overriden by using the rt_entries boot option: IP route cache hash table entries: 524288 (order: 6, 4194304 bytes) With this patch rt_worker_func now takes 0.460 ms on the same system.

* vlan: update vlan carrier state for admin up/downJay Vosburgh2009-04-252-0/+7
| | | | | | | | | | | | | | | | | | | Currently, the VLAN event handler does not adjust the VLAN device's carrier state when the real device or the VLAN device is set administratively up or down. The following patch adds a transfer of operating state from the real device to the VLAN device when the real device is administratively set up or down, and sets the carrier state up or down during init, open and close of the VLAN device. This permits observers above the VLAN device that care about the carrier state (bonding's link monitor, for example) to receive updates for administrative changes by more closely mimicing the behavior of real devices.

| * netfilter: xt_recent: fix stack overread in compat codeJan Engelhardt2009-04-241-5/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Related-to: commit 325fb5b4d26038cba665dd0d8ee09555321061f0 The compat path suffers from a similar problem. It only uses a __be32 when all of the recent code uses, and expects, an nf_inet_addr everywhere. As a result, addresses stored by xt_recents were filled with whatever other stuff was on the stack following the be32.

| | | | | | | | | | | | | | | | | | | | | | This patch adds missing role attribute to the DCCP type, otherwise the creation of entries is not of any use. The attribute added is CTA_PROTOINFO_DCCP_ROLE which contains the role of the conntrack original tuple.

The DCCP and UDP-Lite IPv6 protocols were missed in this conversion, add the required callback pointer.

| * netfilter: bridge: allow fragmentation of VLAN packets traversing a bridgehummerbliss@gmail.com2009-04-201-1/+9
| | | | | | | | | | | | | | | | | | | | | | | | br_nf_dev_queue_xmit only checks for ETH_P_IP packets for fragmenting but not VLAN packets. This results in dropping of large VLAN packets. This can be observed when connection tracking is enabled. Connection tracking re-assembles fragmented packets, and these have to re-fragmented when transmitting out. Also, make sure only refragmented packets are defragmented as per suggestion from Patrick McHardy.

* | netlabel: Always remove the correct address selectorPaul Moore2009-04-221-16/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The NetLabel address selector mechanism has a problem where it can get mistakenly remove the wrong selector when similar addresses are used. The problem is caused when multiple addresses are configured that have different netmasks but the same address, e.g. 127.0.0.0/8 and 127.0.0.0/24. This patch fixes the problem.
