git://git.kernel.org/pub/scm/linux/kernel/git/linville/wireless John Linville says: Here are three more fixes that some of my developers are desperate to see included in 3.4... Johan Hedberg went to some length justifyng the inclusion of these two Bluetooth fixes: "The device_connected fix should be quite self-explanatory, but it's actually a wider issue than just for keyboards. All profiles that do incoming connection authorization (e.g. headsets) will break without it with specific hardware. The reason it wasn't caught earlier is that it only occurs with specific Bluetooth adapters. As for the security level patch, this fixes L2CAP socket based security level elevation during a connection. The HID profile needs this (for keyboards) and it is the only way to achieve the security level elevation when using the management interface to talk to the kernel (hence the management enabling patch being the one that exposes this" The rtlwifi fix addresses a regression related to firmware loading, as described in kernel.org bug 43187. It basically just moves a hunk of code to a more appropriate place. Signed-off-by: David S. Miller <davem@davemloft.net>

2012-05-15usbnet: fix skb traversing races during unlink(v2)Ming Lei1-16/+38
Commit 4231d47e6fe69f061f96c98c30eaf9fb4c14b96d(net/usbnet: avoid recursive locking in usbnet_stop()) fixes the recursive locking problem by releasing the skb queue lock before unlink, but may cause skb traversing races: - after URB is unlinked and the queue lock is released, the refered skb and skb->next may be moved to done queue, even be released - in skb_queue_walk_safe, the next skb is still obtained by next pointer of the last skb - so maybe trigger oops or other problems This patch extends the usage of entry->state to describe 'start_unlink' state, so always holding the queue(rx/tx) lock to change the state if the referd skb is in rx or tx queue because we need to know if the refered urb has been started unlinking in unlink_urbs. The other part of this patch is based on Huajun's patch: always traverse from head of the tx/rx queue to get skb which is to be unlinked but not been started unlinking.

2012-05-10bonding: don't increase rx_dropped after processing LACPDUsJiri Bohac3-12/+24
Since commit 3aba891d, bonding processes LACP frames (802.3ad mode) with bond_handle_frame(). Currently a copy of the skb is made and the original is left to be processed by other rx_handlers and the rest of the network stack by returning RX_HANDLER_ANOTHER. As there is no protocol handler for PKT_TYPE_LACPDU, the frame is dropped and dev->rx_dropped increased. Fix this by making bond_handle_frame() return RX_HANDLER_CONSUMED if bonding has processed the LACP frame. Signed-off-by: Jiri Bohac <jbohac@suse.cz> Signed-off-by: David S.

2012-05-10ehea: fix losing of NEQ events when one event occurred earlyThadeu Lima de Souza Cascardo1-0/+2
The NEQ interrupt is only triggered when there was no previous pending interrupt. If we request irq handling after an interrupt has occurred, we will never get an interrupt until we call H_RESET_EVENTS. Events seem to be cleared when we first register the NEQ. So, when we requested irq handling right after registering it, a possible race with an interrupt was much less likely. Now, there is a chance we may lose this race and never get any events. The fix here is to poll and acknowledge any events that might have happened right after registering the irq handler.

2012-05-08sfc: Fix division by zero when using one RX channel and no SR-IOVBen Hutchings1-1/+1
If RSS is disabled on the PF (efx->n_rx_channels == 1) we try to set up the indirection table so that VFs can use it, setting efx->rss_spread = efx_vf_size(efx). But if SR-IOV was disabled at compile time, this evaluates to 0 and we end up dividing by zero when initialising the table. I considered changing the fallback definition of efx_vf_size() to return 1, but its value is really meaningless if we are not going to enable VFs. Therefore add a condition of efx_sriov_wanted(efx) in efx_probe_interrupts(). Signed-off-by: Ben Hutchings <bhutchings@solarflare.com>

Some RNDIS devices include a bogus CDC Union descriptor pointing to non-existing interfaces. The RNDIS code is already prepared to handle devices without a CDC Union descriptor by hardwiring the driver to use interfaces 0 and 1, which is correct for the devices with the bogus descriptor as well. So we can reuse the existing workaround.

2012-05-06bnx2x: bug fix when loading after SAN bootAriel Elior1-1/+22
This is a bug fix for an "interface fails to load" issue. The issue occurs when bnx2x driver loads after UNDI driver was previously loaded over the chip. In such a scenario the UNDI driver is loaded and operates in the pre-boot kernel, within its own specific host memory address range. When the pre-boot stage is complete, the real kernel is loaded, in a new and distinct host memory address range. The transition from pre-boot stage to boot is asynchronous from UNDI point of view. A race condition occurs when UNDI driver triggers a DMAE transaction to valid host addresses in the pre-boot stage, when control is diverted to the real kernel. This results in access to illegal addresses by our HW as the addresses which were valid in the preboot stage are no longer considered valid. Specifically, the 'was_error' bit in the pci glue of our device is set. This causes all following pci transactions from chip to host to timeout (in accordance to the pci spec).

2012-05-04igb, ixgbe: netdev_tx_reset_queue incorrectly called from tx init pathJohn Fastabend3-4/+6
igb and ixgbe incorrectly call netdev_tx_reset_queue() from i{gb|xgbe}_clean_tx_ring() this sort of works in most cases except when the number of real tx queues changes. When the number of real tx queues changes netdev_tx_reset_queue() only gets called on the new number of queues so when we reduce the number of queues we risk triggering the watchdog timer and repeated device resets. So this is not only a cosmetic issue but causes real bugs. For example enabling/disabling DCB or FCoE in ixgbe will trigger this.

By default, iwlwifi uses order-1 pages (8 KB) to store incoming frames, but doesnt say so in skb->truesize. This makes very possible to exhaust kernel memory since these skb evade normal socket memory accounting. As struct ieee80211_hdr is going to be pulled before calling IP stack, there is no need to use dev_alloc_skb() to reserve NET_SKB_PAD bytes. alloc_skb() is ok in this driver, allowing more tailroom.

This reverts commit a844adfd7bee4edc66d337de6c33b348e83552a8. The commit a844adfd is degrading rx sensitivity of lower rate in HT40 mode and it is confirmed that reverting the change is improving rx sensitivity. spur_freq_sd (for self-corr in AGC) is defined with respect to the center of each 20MHz channel while spur_phase_delta (for self-corr in Rx and spur data filter) is defined with respect to the center of current RF channel. So in short, we need to subtract spur_freq_sd (for self-corr in AGC) by the offset between the center of primary20 and the center of RF channel in SW. This offset could be +/10 MHz for dynamic 40.

2012-05-01sky2: fix receive length error in mixed non-VLAN/VLAN trafficstephen hemminger2-12/+17
Bug: The VLAN bit of the MAC RX Status Word is unreliable in several older supported chips. Sometimes the VLAN bit is not set for valid VLAN packets and also sometimes the VLAN bit is set for non-VLAN packets that came after a VLAN packet. This results in a receive length error when VLAN hardware tagging is enabled. Fix: Variation on original fix proposed by Mirko. The VLAN information is decoded in the status loop, and can be applied to the received SKB there. This eliminates the need for the separate tag field in the interface data structure. The tag has to be copied and cleared if packet is copied. This version checked out with vlan and normal traffic. Note: vlan_tx_tag_present should be renamed vlan_tag_present, but that is outside scope of this.

2012-04-30smsc75xx: fix mdio reads and writesSteve Glendinning1-2/+2
smsc75xx needs MII_ACCESS_BUSY to be set to correctly trigger mdio I/O. Note smsc75xx is different from smsc95xx in this regard.

2012-04-30smsc75xx: mark link down on startup and let PHY interrupt deal with carrier ↵Steve Glendinning1-1/+1
changes This patch fixes the same issue as reported on smsc95xx, where the usb device is connected with no ethernet cable plugged-in. Without this patch sysfs reports the cable as present flag@flag-desktop:~$ cat /sys/class/net/eth0/carrier 1 while it's not: flag@flag-desktop:~$ sudo mii-tool eth0 eth0: no link Signed-off-by: Steve Glendinning <steve.glendinning@shawell.net> Signed-off-by: David S.

2012-04-27wl1251: fix crash on remove due to leftover work itemGrazvydas Ignotas1-0/+1
This driver currently leaves elp_work behind when stopping, which occasionally results in data corruption because work function ends up accessing freed memory, typical symptoms of this are various worker_thread crashes. Fix it by cancelling elp_work. Cc: stable@vger.kernel.org # v2.6.37+ Signed-off-by: Grazvydas Ignotas <notasas@gmail.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2012-04-27wl1251: fix crash on remove due to premature kfreeGrazvydas Ignotas1-1/+1
Currently SDIO glue frees it's own structure before calling wl1251_free_hw(), which in turn calls ieee80211_unregister_hw(). The later call may result in a need to communicate with the chip to stop it (as it happens now if the interface is still up before rmmod), which means calls are made back to the glue, resulting in freed memory access. Fix this by freeing glue data last. Cc: stable@vger.kernel.org # v2.6.37+ Signed-off-by: Grazvydas Ignotas <notasas@gmail.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2012-04-27b43: only reload config after successful initializationSeth Forshee1-2/+8
Commit 2a19032 (b43: reload phy and bss settings after core restarts) introduced an unconditional call to b43_op_config() at the end of b43_op_start(). When firmware fails to load this can wedge the system. There's no need to reload the configuration after a failed initialization anyway, so only make the call if initialization was successful.
