* b44: the poll handler b44_poll must not enable IRQ unconditionallyDongdong Deng2009-09-16
| | | | | | | | | | | | | | | | | | | | | | net/core/netpoll.c::netpoll_send_skb() calls the poll handler when it is available. As netconsole can be used from almost any context, IRQ must not be enabled blindly in the NAPI handler of the driver which supports netpoll. Call trace: netpoll_send_skb() { local_irq_save(flags) -> netpoll_poll() -> poll_napi() -> poll_one_napi() -> napi->poll() -> b44_poll() local_irq_restore(flags) } Signed-off-by: Dongdong Deng <dongdong.deng@windriver.com> Signed-off-by: David S.

* bonding: make ab_arp select active slaves as other modesJiri Pirko2009-09-16
| | | | | | | | | | | | | When I was implementing primary_passive option (formely named primary_lazy) I've run into troubles with ab_arp. This is the only mode which is not using bond_select_active_slave() function to select active slave and instead it selects it itself. This seems to be not the right behaviour and it would be better to do it in bond_select_active_slave() for all cases. This patch makes this happen. Please review.

| * iwlwifi: disable powersave for 4965Johannes Berg2009-09-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There's a bug in 4965 powersave that appears to be related to the way it keeps track of its data during sleep, but we haven't found it yet. Due to that, using powersave may spontaneously cause the device to SYSASSERT when transitioning from sleep to wake. Therefore, disable powersave for 4965, until (if ever, unfortunately) we can identify and fix the problem. Cf. http://bugzilla.intellinuxwireless.org/show_bug.cgi?id=1982 which was closed, but now has re-appeared with IDLE mode, which probably means we never really fixed it.

| * iwlwifi: fix potential rx buffer lossReinette Chatre2009-09-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | RX handling maintains a few lists that keep track of the RX buffers. Buffers move from one list to the other as they are used, replenished, and again made available for usage. In one such instance, when a buffer is used it enters the "rx_used" list. When buffers are replenished an skb is attached to the buffer and it is moved to the "rx_free" list. The problem here is that the buffer is first removed from the "rx_used" list _before_ the skb is allocated. Thus, if the skb allocation fails this buffer remains removed from the "rx_used" list and is thus lost for future usage. Fix this by first allocating the skb before trying to attach it to a list. We add an additional check to not do this unnecessarily. Reported-by: Rick Farrington <rickdic@hotmail.com> Signed-off-by: Reinette Chatre <reinette.chatre@intel.com> Signed-off-by: John W.

| | | | | | | | | | | | | | | | | | | | | | | | This fixes a resume failure where a signal is pending on resume so the firmware upload fails. This removes the interruptible sleep, because we don't really need it. In the worst case (with broken firmware) the sleep loop will take 1 second. In the common case (working firmware), it will only take a few milliseconds. So we don't really need to be interruptible. Signed-off-by: Michael Buesch <mb@bu3sch.de> Signed-off-by: John W.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As the hostap driver was converted to use net_device_ops, a mistake was made in hostap_main.c (commit 5ae4efbcd2611562a8b93596be034e63495706a5). Originally, the tx_queue_len was set to 0 for every other interface than HOSTAP_INTERFACE_MASTER, but the new fragment of code sets tx_queue_len to 0 only for HOSTAP_INTERFACE_MASTER. The opposite of the previous behavior makes the driver to drop all packets in AP mode. Change the way 0 is assigned to tx_queue_len according to the original logic.

* | bonding: remap muticast addresses without using dev_close() and dev_open()Moni Shoua2009-09-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch fixes commit e36b9d16c6a6d0f59803b3ef04ff3c22c3844c10. The approach there is to call dev_close()/dev_open() whenever the device type is changed in order to remap the device IP multicast addresses to HW multicast addresses. This approach suffers from 2 drawbacks: *. It assumes tha the device is UP when calling dev_close(), or otherwise dev_close() has no affect. It is worth to mention that initscripts (Redhat) and sysconfig (Suse) doesn't act the same in this matter. *. dev_close() has other side affects, like deleting entries from the routing table, which might be unnecessary. The fix here is to directly remap the IP multicast addresses to HW multicast addresses for a bonding device that changes its type, and nothing else.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The packet split feature was recently moved out of the adapter-wide flags feature field and into a per-Rx ring feature field. In the process, packet split isn't properly disabled in the Rx ring if the adapter has it globally disabled, followed by a device reset. This won't impact the driver today, since it's always in packet split mode. However, this will prevent any pitfalls if someone disables packet split on the adapter in the future and doesn't disable it in each ring.

| * | net: Add DEVTYPE support for Ethernet based devicesMarcel Holtmann2009-09-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Ethernet framing is used for a lot of devices these days. Most prominent are WiFi and WiMAX based devices. However for userspace application it is important to classify these devices correctly and not only see them as Ethernet devices. The daemons like HAL, DeviceKit or even NetworkManager with udev support tries to do the classification in userspace with a lot trickery and extra system calls. This is not good and actually reaches its limitations. Especially since the kernel does know the type of the Ethernet device it is pretty stupid. To solve this problem the underlying device type needs to be set and then the value will be exported as DEVTYPE via uevents and available within udev. # cat /sys/class/net/wlan0/uevent DEVTYPE=wlan INTERFACE=wlan0 IFINDEX=5 This is similar to subsystems like USB and SCSI that distinguish between hosts, devices, disks, partitions etc. The new SET_NETDEV_DEVTYPE() is a convenience helper to set the actual device type. All device types are free form, but for convenience the same strings as used with RFKILL are choosen. Signed-off-by: Marcel Holtmann <marcel@holtmann.org> Signed-off-by: David S.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The txq_set_wrr() function in drivers/net/mv643xx_eth.c is unused, not even referenced under #if 0 or something like that, which results in a compile-time warning: drivers/net/mv643xx_eth.c:1070: warning: 'txq_set_wrr' defined but not used Fix: remove it.

PHY: mdio@e0102120:00 - Link is Up - 1000/Full sh-3.00# ethtool -s eth0 speed 100 duplex half autoneg off PHY: mdio@e0102120:00 - Link is Down PHY: mdio@e0102120:00 - Link is Up - 100/Half NETDEV WATCHDOG: eth0 (ucc_geth): transmit queue 0 timed out ------------[ cut here ]------------ Badness at c01fcbd0 [verbose debug info unavailable] NIP: c01fcbd0 LR: c01fcbd0 CTR: c0194e44 ... The cure is to disable the controller before changing speed/duplex and enable it afterwards. Though, disabling the controller might take quite a while, so we better not grab any spinlocks in adjust_link(). Instead, we quiesce the driver's activity, and only then disable the controller.

| | | | | | | | | | | | | | | | | | | | | | | | | | | According to specs, when auto-negotiation is disabled, Marvell PHYs need a software reset after changing speed/duplex forcing bits. Otherwise, the modified bits have no effect. Signed-off-by: Anton Vorontsov <avorontsov@ru.mvista.com> Signed-off-by: David S. Miller <davem@davemloft.net>
