A user reported that he couldn't load the driver because the rfkill line was pulled up while we were running the calibrations. This was happening while booting the system: systemd was restoring the "disable wifi settings" and that raised an RFKILL interrupt during the calibration. Our driver didn't handle that properly and this is now fixed." Signed-off-by: John W. Linville <linville@tuxdriver.com>
| * | iwlwifi: fix RFkill while calibratingEmmanuel Grumbach2014-11-035-4/+23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If the RFkill interrupt fires while we calibrate, it would make the firmware fail and the driver wasn't able to recover. Change the flow so that the driver will kill the firmware in that case. Since we have now two flows that are calling trans_stop_device (the RFkill interrupt and the op_mode_mvm_start function) - we need to better sync this. Use the STATUS_DEVICE_ENABLED in the pcie transport in an atomic way to achieve this.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | mvm->cur_ucode wasn't set before we actually load the firmware. This caused issues when we boot in RFKILL since we get an RFKILL interrupt upon boot even before we load any firmware. This leads to issues since iwl_mvm_set_hw_rfkill_state (the RFKILL interrupts handler in mvm) relies on this variable. Fix this. Signed-off-by: Emmanuel Grumbach <emmanuel.grumbach@intel.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | During 11n RX reordering, if there is a hole in RX table, driver will not send packets to kernel until the rxreorder timer expires or the table is full. However, currently driver always restarts rxreorder timer when receiving a packet, which causes the timer hardly to expire. So while connected with to 11n AP in a busy environment, ping packets may get blocked for about 30 seconds. This patch fixes this timer restarting by ensuring rxreorder timer would only be restarted either timer is not set or start_win has changed.

| * | iwlwifi: dvm: drop non VO frames when flushingEmmanuel Grumbach2014-10-231-11/+13

Until now, iwldvm implemented this by waiting that all the frames are sent (ACKed or timeout). In case of weak signal, this can take a significant amount of time, delaying the next connection (in case of roaming). Many users have reported that the flush would take too long leading to the following error messages to be printed: iwlwifi 0000:03:00.0: fail to flush all tx fifo queues Q 2 iwlwifi 0000:03:00.0: Current SW read_ptr 161 write_ptr 201 iwl data: 00000000: 00 00 00 00 00 00 00 00 fe ff 01 00 00 00 00 00 [snip] iwlwifi 0000:03:00.0: FH TRBs(0) = 0x00000000 [snip] iwlwifi 0000:03:00.0: Q 0 is active and mapped to fifo 3 ra_tid 0x0000 [9,9] [snip] Instead of waiting for these packets, simply drop them. This significantly improves the responsiveness of the network. Note that all the queues are flushed, but the VO one. This is not typically used by the applications and it likely contains management frames that are useful for connection or roaming.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently the allowed "respose rate" set (rates for HW generated frames like ACKs) is the same as the basic rate set. The HW will use the higher allowed response rate that is lower than the rate of the received frame. This is more or less what IEEE80211 mandates, but I missed the fact that IEEE80211 also says that whenever it happens that for a modulation class there is no any rate in the basic rates set, then the response rate set shall include also all the mandatory rates for that modulation class. This patch adds mandatory OFDM rates to the allowed response rate set if no OFDM rate is included in the basic rate set. Depending by the AP, I faced cases in which this patch seems to cause a noticeable perfomance improvement. - With my usual test AP there is no particular perfomance difference. - With a prism54/hostapd AP this patch causes RX thoughput increase from about 5Mbps to about 20Mbps. Hopefully this patch may help people that faced performance regression wrt the old staging driver. Signed-off-by: Andrea Merello <andrea.merello@gmail.com> Signed-off-by: John W.

This is the result of discussions back in Chicago, and the hard work of several individuals. Now, when the ->ndo_start_xmit() method of a driver sees skb->xmit_more as true, it can choose to defer the doorbell telling the driver to start processing the new TX queue entires. skb->xmit_more means that the generic networking is guaranteed to call the driver immediately with another SKB to send. There is logic added to the qdisc layer to dequeue multiple packets at a time, and the handling mis-predicted offloads in software is now done with no locks held. Finally, pktgen is extended to have a "burst" parameter that can be used to test a multi-send implementation. Several drivers have xmit_more support: i40e, igb, ixgbe, mlx4, virtio_net Adding support is almost trivial, so export more drivers to support this optimization soon. I want to thank, in no particular or implied order, Jesper Dangaard Brouer, Eric Dumazet, Alexander Duyck, Tom Herbert, Jamal Hadi Salim, John Fastabend, Florian Westphal, Daniel Borkmann, David Tat, Hannes Frederic Sowa, and Rusty Russell. 2) PTP and timestamping support in bnx2x, from Michal Kalderon. 3) Allow adjusting the rx_copybreak threshold for a driver via ethtool, and add rx_copybreak support to enic driver. From Govindarajulu Varadarajan. 4) Significant enhancements to the generic PHY layer and the bcm7xxx driver in particular (EEE support, auto power down, etc.) from Florian Fainelli. 5) Allow raw buffers to be used for flow dissection, allowing drivers to determine the optimal "linear pull" size for devices that DMA into pools of pages. The objective is to get exactly the necessary amount of headers into the linear SKB area pre-pulled, but no more. The new interface drivers use is eth_get_headlen(). From WANG Cong, with driver conversions (several had their own by-hand duplicated implementations) by Alexander Duyck and Eric Dumazet. 6) Support checksumming more smoothly and efficiently for encapsulations, and add "foo over UDP" facility. From Tom Herbert. 7) Add Broadcom SF2 switch driver to DSA layer, from Florian Fainelli. 8) eBPF now can load programs via a system call and has an extensive testsuite. Alexei Starovoitov and Daniel Borkmann. 9) Major overhaul of the packet scheduler to use RCU in several major areas such as the classifiers and rate estimators. From John Fastabend. 10) Add driver for Intel FM10000 Ethernet Switch, from Alexander Duyck. 11) Rearrange TCP_SKB_CB() to reduce cache line misses, from Eric Dumazet. 12) Add Datacenter TCP congestion control algorithm support, From Florian Westphal. 13) Reorganize sk_buff so that __copy_skb_header() is significantly faster.

Linville says: ==================== pull request: wireless-next 2014-10-03 Please pull tihs batch of updates intended for the 3.18 stream! For the iwlwifi bits, Emmanuel says: "I have here a few things that depend on the latest mac80211's changes: RRM, TPC, Quiet Period etc... Eyal keeps improving our rate control and we have a new device ID. This last patch should probably have gone to wireless.git, but at that stage, I preferred to send it to -next and CC stable." For (most of) the Atheros bits, Kalle says: "The only new feature is testmode support from me. Ben added a new method to crash the firmware with an assert for debug purposes. As usual, we have lots of smaller fixes from Michal. Matteo fixed a Kconfig dependency with debugfs. I fixed some warnings recently added to checkpatch." For the NFC bits, Samuel says: "We've had major updates for TI and ST Microelectronics drivers, and a few NCI related changes. For TI's trf7970a driver: - Target mode support for trf7970a - Suspend/resume support for trf7970a - DT properties additions to handle different quirks - A bunch of fixes for smartphone IOP related issues For ST Microelectronics' ST21NFCA and ST21NFCB drivers: - ISO15693 support for st21nfcb - checkpatch and sparse related warning fixes - Code cleanups and a few minor fixes Finally, Marvell added ISO15693 support to the NCI stack, together with a couple of NCI fixes." For the Bluetooth bits, Johan says: "This 3.18 pull request replaces the one I did on Monday ("bluetooth-next 2014-09-22", which hasn't been pulled yet). The additions since the last request are: - SCO connection fix for devices not supporting eSCO - Cleanups regarding the SCO establishment logic - Remove unnecessary return value from logging functions - Header compression fix for 6lowpan - Cleanups to the ieee802154/mrf24j40 driver Here's a copy from previous request that this one replaces: ' Here are some more patches for 3.18. They include various fixes to the btusb HCI driver, a fix for LE SMP, as well as adding Jukka to the MAINTAINERS file for generic 6LoWPAN (as requested by Alexander Aring). I've held on to this pull request a bit since we were waiting for a SCO related fix to get sorted out first. However, since the merge window is getting closer I decided not to wait for it. If we do get the fix sorted out there'll probably be a second small pull request later this week. '" And, "Unless 3.17 gets delayed this will probably be our last -next pull request for 3.18. We've got: - New Marvell hardware supportr - Multicast support for 6lowpan - Several of 6lowpan fixes & cleanups - Fix for a (false-positive) lockdep warning in L2CAP - Minor btusb cleanup" On top of all that comes the usual sort of updates to ath5k, ath9k, ath10k, brcmfmac, mwifiex, and wil6210. This time around there are also a number of rtlwifi updates to enable some new hardware and to reconcile the in-kernel drivers with some newer releases of the Realtek vendor drivers. Also of note is some device tree work for the bcma bus. Please let me know if there are problems! ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
