2013-07-25b43: ensue that BCMA is "y" when B43 is "y"Hauke Mehrtens1-2/+2
commit 693026ef2e751fd94d2e6c71028e68343cc875d5 upstream. When b43 gets build into the kernel and it should use bcma we have to ensure that bcma was also build into the kernel and not as a module. In this patch this is also done for SSB, although you can not build b43 without ssb support for now. This fixes a build problem reported by Randy Dunlap in 5187EB95.2060605@infradead.org Reported-By: Randy Dunlap <rdunlap@infradead.org> Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de> Signed-off-by: John W.

2013-07-25ath9k: Do not assign noise for NULL caldataSujith Manoharan1-1/+0
commit d3bcb7b24bbf09fde8405770e676fe0c11c79662 upstream. ah->noise is maintained globally and not per-channel. This is updated in the reset() routine after the NF history has been filled for the *current channel*, just before switching to the new channel. There is no need to do it inside getnf(), since ah->noise must contain a value for the new channel. Signed-off-by: Sujith Manoharan <c_manoha@qca.qualcomm.com> Signed-off-by: John W.

2013-07-25ath9k: Fix noisefloor calibrationSujith Manoharan2-8/+2
commit 696df78509d1f81b651dd98ecdc1aecab616db6b upstream. The commits, "ath9k: Fix regression in channelwidth switch at the same channel" "ath9k: Fix invalid noisefloor reading due to channel update" attempted to fix noisefloor calibration when a channel switch happens due to HT20/HT40 bandwidth change. This is causing invalid readings resulting in messages like: "ath: phy16: NF[0] (-45) > MAX (-95), correcting to MAX". This results in an incorrect noise being used initially for reporting the signal level of received packets, until NF calibration is done and the history buffer is updated via the ANI timer, which happens much later. When a bandwidth change happens, it is appropriate to reset the internal history data for the channel. Do this correctly in the reset() routine by checking the "chanmode" variable.

commit 0847beb2865f5ef1c8626ec1a37def18f3d6c41a upstream. The code writes the default_power2 value into the TX field of the RFCSR50 register, however the condition in the if statement uses default_power1. Due to this, wrong TX power value might be written into the register. Use the correct value in the condition to fix the issue. Compile tested only.

commit 0a6f3a8ebaf13407523c2c7d575b4ca2debd23ba upstream. The current code uses the same index value both for the channel information array and for the TX power table. The index starts from 14, however the index of the TX power table must start from zero. Fix it, in order to get the correct TX power value for a given channel.

commit 8a487b1a7432b20ff3f82387a8ce7555a964b44e upstream. When the queue is unmapped while it was so loaded that mac80211's was stopped, we need to wake the queue after having freed all the packets in the queue. Not doing so can result in weird stuff like: * run lots of traffic (mac80211's queue gets stopped) * RFKILL * de-assert RFKILL * no traffic Signed-off-by: Emmanuel Grumbach <emmanuel.grumbach@intel.com> Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

commit b967613d7e7c7bad176f5627c55e2d8c5aa2480e upstream. When a queue is disabled, it frees all its entries. Later, the op_mode might still get notifications from the firmware that triggers to free entries in the tx queue. The transport should be prepared for these races and know to ignore reclaim calls on queues that have been disabled and whose entries have been freed.

2013-06-25net/tg3: Avoid delay during MMIO accessGavin Shan1-0/+36
When the EEH error is the result of a fenced host bridge, MMIO accesses can be very slow (milliseconds) to timeout and return all 1's, thus causing the driver various timeout loops to take way too long and trigger soft-lockup warnings (in addition to taking minutes to recover). It might be worthwhile to check if for any of these cases, ffffffff is a valid possible value, and if not, bail early since that means the HW is either gone or isolated. In the meantime, checking that the PCI channel is offline would be workaround of the problem.

Many of these are one- or two-liners, and a couple of others are mostly relocating existing code to avoid races or to limit the code to effecting specific hardware, etc. The mac80211 fixes have a couple of exceptions to the above. Regarding those, Johannes says: "Following davem's complaint about my patch, here's a new pull request w/o the patch he was complaining about, but instead with the const fix rolled into the fix. I have a fix for radar detection, one for rate control and a workaround for broken HT APs which is a regression fix because we didn't rely on them to be correct before." Johannes also sends some iwlwifi fixes: "I picked up Nikolay's patch for the chain noise calibration bug that seems to have been there forever, a fix from Emmanuel for setting TX flags on BAR frames and a fix of my own to avoid printing request_module() errors if the kernel isn't even modular. We also have our own version of Stanislaw's fix for rate control." Along with those... Anderson Lizardo fixes a Bluetooth memory corruption bug when an MTU value is set to too small of a value. Arend van Spriel sends a revised brcmsmac bug that fixes a regression caused by a bad return value in an earlier patch. He also sends a brcmfmac fix to avoid an oops when loading the driver at boot. Daniel Drake fixes a race condition in btmrvl that causes hangs on suspend for OLPC hardware. Johan Hedberg adds a check to avoid sending a HCI_Delete_Stored_Link_Key command to devices that don't support them, avoiding some scary looking log spam. Stanislaw Gruszka gives us a fix for iwlegacy to be able to use rates higher than 1Mb/s on older wireless networks.

2013-06-17alx: add a simple AR816x/AR817x device driverJohannes Berg9-0/+4568
This is a very simple driver, based on the original vendor driver that Qualcomm/Atheros published/submitted previously, but reworked to make the code saner. However, it also lost a number of features (TSO/GSO, VLAN acceleration and multi- queue support) in the process, as well as debugging support features I didn't have any use for. The only thing I left is checksum offload. More features can obviously be added, but this seemed like a good start for having a driver in mainline at all.

We should call __vlan_hwaccel_put_tag() only if the packet comes from vlan, otherwise VLAN_TAG_PRESENT will always be added.

If skb_clone fails if out of memory then just skip the fanout. Problem was introduced in 3.10 with: commit 6681712d67eef14c4ce793561c3231659153a320 Author: David Stevens <dlstevens@us.ibm.com> Date: Fri Mar 15 04:35:51 2013 +0000 vxlan: generalize forwarding tables Signed-off-by: Stephen Hemminger <stephen@networkplumber.org> Signed-off-by: David S.

2013-06-17vxlan: only migrate dynamic FDB entriesstephen hemminger1-4/+12
Only migrate dynamic forwarding table entries, don't modify static entries. If packet received from incorrect source IP address assume it is an imposter and drop it. This patch applies only to -net, a different patch would be needed for earlier kernels since the NTF_SELF flag was introduced with 3.10.

2013-06-17vxlan: fix race between flush and incoming learningstephen hemminger1-7/+9
It is possible for a packet to arrive during vxlan_stop(), and have a dynamic entry created. Close this by checking if device is up.
