2014-02-17netdevice: add queue selection fallback handler for ndo_select_queueDaniel Borkmann14-18/+18
Add a new argument for ndo_select_queue() callback that passes a fallback handler. This gets invoked through netdev_pick_tx(); fallback handler is currently __netdev_pick_tx() as most drivers invoke this function within their customized implementation in case for skbs that don't need any special handling. This fallback handler can then be replaced on other call-sites with different queue selection methods (e.g. in packet sockets, pktgen etc). This also has the nice side-effect that __netdev_pick_tx() is then only invoked from netdev_pick_tx() and export of that function to modules can be undone. Suggested-by: David S.

2014-02-15net: of_mdio: fix of_set_phy_supported after driver probingFlorian Fainelli1-1/+5
Commit 8fdade4 ("net: of_mdio: parse "max-speed" property to set PHY supported features") introduced a typo in of_set_phy_supported for the first assignment of phydev->supported which will not effectively limit the PHY device supported features bits if the PHY driver contains "higher" features (e.g: max-speed = <100> and PHY driver has PHY_GBIT_FEATURES set). Fix this by making sure that the very first thing is to reset to sane defaults (PHY_BASIC_FEATURES) and then progressively add speed features as we parse them.

2014-02-15net: asix: add missing flag to struct driver_infoEmil Goode1-1/+2
The struct driver_info ax88178_info is assigned the function asix_rx_fixup_common as it's rx_fixup callback. This means that FLAG_MULTI_PACKET must be set as this function is cloning the data and calling usbnet_skb_return. Not setting this flag leads to usbnet_skb_return beeing called a second time from within the rx_process function in the usbnet module.

2014-02-14net:phy:dp83640: Move all HW initialization to dp83640_config_initStefan Sørensen1-5/+8
phy_init_hw not does a full PHY reset after the driver probe has finished, so any hw initialization done in the probe will be lost. Part of the timestamping functionality of the dp83640 is set up in the probe and with that lost, enabling timestamping will cause a PHY lockup, requiring a hard reset / power cycle to recover. This patch moves all the HW initialization in dp83640_probe to dp83640_config_init. Signed-off-by: Stefan Sørensen <stefan.sorensen@spectralink.com> Signed-off-by: David S.

2014-02-14vhost: fix a theoretical race in device cleanupMichael S. Tsirkin1-0/+6
vhost_zerocopy_callback accesses VQ right after it drops a ubuf reference. In theory, this could race with device removal which waits on the ubuf kref, and crash on use after free. Do all accesses within rcu read side critical section, and synchronize on release. Since callbacks are always invoked from bh, synchronize_rcu_bh seems enough and will help release complete a bit faster. Signed-off-by: Michael S.

2014-02-14vhost: fix ref cnt checking deadlockMichael S. Tsirkin1-21/+20
vhost checked the counter within the refcnt before decrementing. It really wanted to know that it is the one that has the last reference, as a way to batch freeing resources a bit more efficiently. Note: we only let refcount go to 0 on device release. This works well but we now access the ref counter twice so there's a race: all users might see a high count and decide to defer freeing resources. In the end no one initiates freeing resources until the last reference is gone (which is on VM shotdown so might happen after a looooong time). Let's do what we probably should have done straight away: switch from kref to plain atomic, documenting the semantics, return the refcount value atomically after decrement, then use that to avoid the deadlock.

2014-02-14bonding: Fix deadlock in bonding driver when using netpolldingtianhong1-0/+7
The bonding driver take write locks and spin locks that are shared by the tx path in enslave processing and notification processing, If the netconsole is in use, the bonding can call printk which puts us in the netpoll tx path, if the netconsole is attached to the bonding driver, result in deadlock. So add protection for these place, by checking the netpoll_block_tx state, we can defer the sending of the netconsole frames until a later time using the retransmit feature of netpoll_send_skb that is triggered on the return code NETDEV_TX_BUSY.

git://git.kernel.org/pub/scm/linux/kernel/git/linville/wireless John W. Linville says: ==================== Please pull this batch of fixes intended for the 3.14 stream! For the mac80211 bits, Johannes says: "This is just a collection of small fixes, the commit logs explain the details. The only thing that isn't strictly a fix is the 5/10 MHz enabling, I had forgotten this and there's little point in waiting longer. The patch simply removes the force-disable code that I put in when there was a problem with the userspace API (that has long been fixed.)" For the iwlwifi bits, Emmanuel says: "I have an important fix that disables A band in case the driver thought it was enabled, and the firmware disagreed. We ended up making the firmware unhappy. I also fix the station table in AP mode and fix the scan while we have BT working. Johannes removes a static variable that could potentially lead to to issues on multi-device setups and disables scheduled scan to avoid issues with old versions of wpa_supplicant. A small fix from David on scan and a few new device IDs for 7265." On top of that... Oleksij Rempel adds a USB ID to the ar5523 driver and changes the default powersave setting for ath9k_htc to "off", due to observed stability issues (based on an equivalent ath9k patch). Stanislaw Gruszka similarly disables powersave for a couple of rt2x00 drivers. He also fixes a couple of scheduling while atomic issues in ath9k_htc. Sujith Manoharan rounds-out the powersave disables with one for ath9k. He also fixes a build prolem with ath9k on ARM and fixes an ath9k Tx power calculation. Finally, Andrea Merello fixes a couple of lingering DMA mapping problems in the rtl8180 driver. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

While we are at it, don't do kmap() under kmap_atomic(), *especially* for a page we'd allocated with GFP_KERNEL. It's spelled "page_address", and had that been more than that, we'd have a real trouble - kmap_high() can block, and doing that while holding kmap_atomic() is a Bad Idea(tm).

2014-02-07bnx2x: Allow VF rss on higher PFsYuval Mintz1-3/+3
bnx2x driver uses incorrect PF identifier to configure (in HW) the VF interrupt scheme; As a result, in multi-function mode the configuration for PFs with a high index (4+) will overflow and the PF will erroneously configure a single ISR scheme for its VFs. As a result, if such a VF uses multiple queues, interrupt generation will stop after VF receives an Rx packet or sends a Tx packet on a queue other than queue[0].

2014-02-07tg3: Fix deadlock in tg3_change_mtu()Nithin Sujir1-2/+2
Quoting David Vrabel - "5780 cards cannot have jumbo frames and TSO enabled together. When jumbo frames are enabled by setting the MTU, the TSO feature must be cleared. This is done indirectly by calling netdev_update_features() which will call tg3_fix_features() to actually clear the flags. netdev_update_features() will also trigger a new netlink message for the feature change event which will result in a call to tg3_get_stats64() which deadlocks on the tg3 lock." tg3_set_mtu() does not need to be under the tg3 lock since converting the flags to use set_bit(). Move it out to after tg3_netif_stop().
