2013-01-02brcmsmac: Use udelay instead of usleep_rangeNiels Ole Salscheider
wlc_lcnphy_rx_iq_cal_gain is called during initialization, i. e. when executing brcms_up. But brcms_up is called from brcms_ops_start while the latter holds a spin lock. Thus, we cannot use usleep_range but have to use udelay.

2013-01-02carl9170: fix -EINVAL bailout during init with !CONFIG_MAC80211_MESHChristian Lamparter
Sean reported that as of 3.7, his AR9170 device no longer works because the driver fails during initialization. He noted this is due to: "In carl9170/fw.c, ar->hw->wiphy is tagged with NL80211_IFTYPE_MESH_POINT support if the firmware has Content after Beacon Queuing. This is both in interface_modes and the only iface_combinations entry. If CONFIG_MAC80211_MESH is not set, ieee80211_register_hw removes NL80211_IFTYPE_MESH_POINT from interface_modes, but not iface_combinations. wiphy_register then checks to see if every interface type in every interface combination is in interface_modes. NL80211_IFTYPE_MESH_POINT was removed, so you get a WARN_ON warning and it returns -EINVAL, giving up." Unfortunately, the iface_combination (types) feature bitmap in ieee80211_iface_limit is part of a const member in the ieee80211_iface_combination struct. Hence, the MESH_POINT feature flag can't be masked by wiphy_register in the same way as interface_modes in ieee80211_register_hw.

2012-12-19ksz884x: fix receive polling race conditionLennert Buytenhek
The ksz884x driver does receive processing in a custom tasklet, and seems to be assuming that since it takes its private interface spinlock with spin_lock_irq(), it won't be running concurrently with its own interrupt handler, as it cannot be preempted by it, but since its interrupt handler doesn't do any locking whatsoever, the receive processing tasklet and interrupt handler can end up running concurrently on different CPUs. As a result of this, the ksz884x receive path ends up locking up fairly easily, when the receive processing tasklet's reenabling of receive interrupts (due to it being done with polling the receive ring) races with the interrupt handler's disabling of receive interrupts (due to a new receive interrupt coming in) resulting in the receive interrupt being masked but the receive processing tasklet not being scheduled. Fix this by making the ksz884x interrupt handler take its private interface spinlock. This requires upgrading the spin_lock() in the transmit cleanup tasklet to a spin_lock_irq(), as otherwise the IRQ handler can preempt transmit cleanup and deadlock the system, but with those two changes, no more receive lockups have been observed.

2012-12-19mlx4_core: Adjustments to Flow Steering activation logic for SR-IOVJack Morgenstein
Separate flow steering capability detection from the decision to activate. For the master (and for native), detect the flow steering capability in mlx4_dev_cap, but activate the appropriate steering type in a new function choose_flow_steering() based on detected data. For VFs, activate flow steering based on what was actually activated by the master, where that info is obtained via QUERY_HCA. This fixes the current VF detection which is wrongly based on QUERY_DEV_CAP. Also, for SR-IOV mode, if flow steering may be activated, do so only if the max number of QPs per rule is sufficient to satisfy one subscription per VF. If not, fall back to B0 mode. This is needed to serve registrations done by L2 network drivers such as mlx4_en and IPoIB when the network stack attempts to join to multicast groups such as all-hosts or the IPoIB broadcast group.

The RX CQ can report completions with invalid frag_idx when the RXQ that was *previously* using it, was not cleaned up properly. This hits a BUG_ON() in be2net. When completion coalescing is enabled on a CQ, an explicit CQ-notify (with rearm) is needed for each compl, to flush partially coalesced CQ entries that are pending DMA. In be_close(), this fix now notifies CQ for each compl, waits explicitly for the flush compl to arrive and complains if it doesn't arrive. Also renaming be_crit_error() to be_hw_error() as it's the more appropriate name and to convey that we don't wait for the flush compl only when a HW error has occurred.

2012-12-18virtio_net: don't rely on virtqueue_add_buf() returning capacity.Rusty Russell
Now we can easily use vq->num_free to determine if there are descriptors left in the queue, we're about to change virtqueue_add_buf() to return 0 on success. The virtio_net driver is the only one which actually uses the return value, so change that. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au> Acked-by: Michael S. Tsirkin <mst@redhat.com>

2012-12-18virtio-net: correct capacity math on ring fullMichael S. Tsirkin
Capacity math on ring full is wrong: we are looking at num_sg but that might be optimistic because of indirect buffer use. The implementation also penalizes fast path with extra memory accesses for the benefit of ring full condition handling which is slow path. It's easy to query ring capacity so let's do just that. This change also makes it easier to move vnet header for tx around as follow-up patch does. Signed-off-by: Michael S.

2012-12-17wireless: fix Atheros drivers compilationVladimir Kondratiev
Bug introduced in commit: wireless: allow Atheros card to not depend on ath.ko Commit in question changed CONFIG_ATH_COMMON to CONFIG_ATH_CARDS as "Atheros card" indication in drivers/net/wireless/ath/Kconfig but it is used also by drivers/net/wireless/Makefile If there are only Atheros cards that do not require ATH_COMMON, whole Makefile for Atheros cards was not executed; and as result, driver won't compile in this case. Change in CONFIG_ option name should be reflected in the drivers/net/wireless/Makefile Signed-off-by: Vladimir Kondratiev <qca_vkondrat@qca.qualcomm.com> Tested-by: Kalle Valo <kvalo@qca.qualcomm.com> Signed-off-by: John W.

2012-12-17rt2x00: zero-out rx_statusGabor Juhos
In commit 'mac80211: support radiotap vendor namespace RX data' new fields were added to 'struct ieee80211_rx_status' and those fileds must be zeroed. However the rt2x00 driver stores driver specific data in the cb array of the rx skbs, so the fields might contain garbage and this can cause unexpected behaviour. The rt2x00 driver from the compat-wireless-2012-12-01 tarball caused the following warning: WARNING: at /devel/ramips/build_dir/target-mipsel_r2_uClibc-0.9.33.2/linux-ramips_rt305x/ compat-wireless-2012-12-01/net/mac80211/rx.c:115 ieee80211_rx_irqsafe+0x274/0xbcc [mac80211]() Modules linked in: dwc_otg ledtrig_usbdev nf_nat_irc nf_nat_ftp nf_conntrack_irc nf_conntrack_ftp ipt_MASQUERADE iptable_nat nf_nat pppoe xt_conntrack xt_CT xt_NOTRACK iptable_raw xt_state nf_conntrack_ipv4 nf_defrag_ipv4 nf_conntrack pppox ipt_REJECT xt_TCPMSS xt_comment xt_multiport xt_mac xt_limit iptable_mangle iptable_filter ip_tables xt_tcpudp x_tables ppp_async ppp_generic slhc rt2800pci(O) rt2800lib(O) rt2x00soc(O) rt2x00pci(O) rt2x00lib(O) mac80211(O) usbcore usb_common nls_base crc_itu_t crc_ccitt eeprom_93cx6 cfg80211(O) compat(O) arc4 aes_generic crypto_blkcipher cryptomgr aead crypto_hash crypto_algapi leds_gpio button_hotplug(O) gpio_keys_polled input_polldev input_core Call Trace: [<801e96b4>] dump_stack+0x8/0x34 [<80010a9c>] warn_slowpath_common+0x78/0xa4 [<80010ae0>] warn_slowpath_null+0x18/0x24 [<80a9710c>] ieee80211_rx_irqsafe+0x274/0xbcc [mac80211] The patch ensures that each field gets initialized with zeroes.
