We have a function (iwl_mvm_scan_size()) that can calculate the scan size for both UMAC and LMAC scans. Use that function instead of calculating manually for LMAC scan and sched scan.

Previously there was a check that compared window->average_tpt to some value, and if it was different - it set it to that value. However, this value was already calculated and set in _rs_collect_tx_data(), so the entire check is unneeded.

Net-detect scans were using the same type as sched scan, which was causing the driver to return -EBUSY and prevent the system from suspending if there was an ongoing scheduled scan. To avoid this, add a new type for net-detect and don't stop anything when it is requested, so that the existing scheduled scan will be resumed when the system wakes up.

All scans are using the unified APIs now, so using "unified" in the symbols is useless and just make them much longer and the main difference between scans now is LMAC vs. UMAC.

Instead of hardcoding the differences between UMAC scans and LMAC scans (which in this case is the number of simultaneous scans that can run), introduce a max_scans variable and stop scans of the other type (i.e. stop sched scan if regular scan is being attempted and vice-versa) if the number of running scans reached the maximum. Add a function that checks if the maximum number of scans was reached and stops the appropriate scan to make room for the new scan.

Now that we have separate flags for stopping scans, we don't need to wait for the scan stopped work to complete before starting the new scan. Previously we needed it because we had no way of distinguishing the scan that was being stopped from the scan that was currently running. With the new flags there won't be any confusions and we are able to handle the stop for the correct type of scan. Thus we can remove the iwl_mvm_cancel_scan_wait_notif() function.

Luciano Coelho authored
LMAC scans cannot handle more than one scan at a time, but UMAC scans can. To avoid confusion we should combine the states of these two types of scans. To do so, we need to support mutliple scans at the same time for UMAC. This commit changes the scan_status element from a single value to a bitmask of running scan types for LMAC. Later, we will modify UMAC scans to use the same state bitmask. Additionally, add stopping scan flags for scheduled and regular scans. This makes it easier to differentiate and handle stop requests triggered by the driver and spontaneous stops generated by the firmware.

Matti Gottlieb authored
When user space requests mac80211 to transmit a frame off channel, mac80211 notifies the driver, and the driver requests a time event from the ucode, and then transmits the frame. When the driver requests a time event, it can specify what is the allowed max delay for starting the time event. When the max delay is too big, this can cause a timeout in the user space, that is waiting for the frame to be transmitted. Currently the max delay is extremely long. Reduce the max delay for the AUX ROC time event that is sent to the ucode.

Eran Harary authored
Our device needs two different firmwares: the INIT firmware and the operational (OPER) firmware. The first one is run when the driver loads and it returns calibrations results as well as the NVM. The second one implements the WiFi protocol. If the wlan interface is not brought up, the device is put to low power state: no firmware will be running. When the interface is brought up, we would run the OPER firmware only and reuse the results of the run of the INIT firmware when the driver was loaded. This is changing with this patch. We now run the INIT firmware every time mac80211 calls start(). The penalty for that is minimal since the INIT firwmare run fast. I now also avoid to power down the device between the INIT and OPER firmware on certains buses. The motivation for this change is that there are components on the device (MFUART) that are triggered by the INIT firmware and need the device to be powered up in order to keep running. Powering the device down between the INIT and OPER firmware would stop these components and prevent them from running again since they are triggered by the INIT firmware only. The new flow allows this and also allows to trigger these components again when the interface is brought up after it has been brought down.

The firmware doesn't relate the scan to a vif. The scan is run by a separate entity called auxiliary MAC (aka AUX MAC). This AUX MAC needs to get Tx power limitations that are not applied on a specific vif, but on the device as a whole. This can be implemented by using the minimum of all the values set by the user for all the MACs. But then we need to ignore the limitations that come from the AP or regulatory for a specific vif: a specific vif might have regulatory limitations because of the channel is works on. This limit is irrelevant for the AUX MAC. Use the new API from mac80211: the user_power_level in bss_conf to achieve this. Firmware -13.ucode has already moved to this API.

Pull networking updates from David Miller: 1) Add BQL support to via-rhine, from Tino Reichardt. 2) Integrate SWITCHDEV layer support into the DSA layer, so DSA drivers can support hw switch offloading. From Floria Fainelli. 3) Allow 'ip address' commands to initiate multicast group join/leave, from Madhu Challa. 4) Many ipv4 FIB lookup optimizations from Alexander Duyck. 5) Support EBPF in cls_bpf classifier and act_bpf action, from Daniel Borkmann. 6) Remove the ugly compat support in ARP for ugly layers like ax25, rose, etc. And use this to clean up the neigh layer, then use it to implement MPLS support. All from Eric Biederman. 7) Support L3 forwarding offloading in switches, from Scott Feldman. 8) Collapse the LOCAL and MAIN ipv4 FIB tables when possible, to speed up route lookups even further. From Alexander Duyck. 9) Many improvements and bug fixes to the rhashtable implementation, from Herbert Xu and Thomas Graf. In particular, in the case where an rhashtable user bulk adds a large number of items into an empty table, we expand the table much more sanely. 10) Don't make the tcp_metrics hash table per-namespace, from Eric Biederman. 11) Extend EBPF to access SKB fields, from Alexei Starovoitov. 12) Split out new connection request sockets so that they can be established in the main hash table. Much less false sharing since hash lookups go direct to the request sockets instead of having to go first to the listener then to the request socks hashed underneath. From Eric Dumazet. 13) Add async I/O support for crytpo AF_ALG sockets, from Tadeusz Struk. 14) Support stable privacy address generation for RFC7217 in IPV6. From Hannes Frederic Sowa. 15) Hash network namespace into IP frag IDs, also from Hannes Frederic Sowa. 16) Convert PTP get/set methods to use 64-bit time, from Richard Cochran. * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-next: (1816 commits) fm10k: Bump driver version to 0.15.2 fm10k: corrected VF multicast update fm10k: mbx_update_max_size does not drop all oversized messages fm10k: reset head instead of calling update_max_size fm10k: renamed mbx_tx_dropped to mbx_tx_oversized fm10k: update xcast mode before synchronizing multicast addresses fm10k: start service timer on probe fm10k: fix function header comment fm10k: comment next_vf_mbx flow fm10k: don't handle mailbox events in iov_event path and always process mailbox fm10k: use separate workqueue for fm10k driver fm10k: Set PF queues to unlimited bandwidth during virtualization fm10k: expose tx_timeout_count as an ethtool stat fm10k: only increment tx_timeout_count in Tx hang path fm10k: remove extraneous "Reset interface" message fm10k: separate PF only stats so that VF does not display them fm10k: use hw->mac.max_queues for stats fm10k: only show actual queues, not the maximum in hardware fm10k: allow creation of VLAN on default vid fm10k: fix unused warnings ...

Pull ARM updates from Russell King: "Included in this update are both some long term fixes and some new features. Fixes: - An integer overflow in the calculation of ELF_ET_DYN_BASE. - Avoiding OOMs for high-order IOMMU allocations - SMP requires the data cache to be enabled for synchronisation primitives to work, so prevent the CPU_DCACHE_DISABLE option being visible on SMP builds. - A bug going back 10+ years in the noMMU ARM94* CPU support code, where it corrupts registers. Found by folk getting Linux running on their cameras. - Versatile Express needs an errata workaround enabled for CPU hot-unplug to work. Features: - Clean up module linker by handling out of range relocations separately from relocation cases we don't handle. - Fix a long term bug in the pci_mmap_page_range() code, which we hope won't impact userspace (we hope there's no users of the existing broken interface.) - Don't map DMA coherent allocations when we don't have a MMU. - Drop experimental status for SMP_ON_UP. - Warn when DT doesn't specify ePAPR mandatory cache properties. - Add documentation concerning how we find the start of physical memory for AUTO_ZRELADDR kernels, detailing why we have chosen the mask and the implications of changing it. - Updates from Ard Biesheuvel to address some issues with large kernels (such as allyesconfig) failing to link. - Allow hibernation to work on modern (ARMv7) CPUs - this appears to have never worked in the past on these CPUs. - Enable IRQ_SHOW_LEVEL, which changes the /proc/interrupts output format (hopefully without userspace breaking... let's hope that if it causes someone a problem, they tell us.) - Fix tegra-ahb DT offsets. - Rework ARM errata 643719 code (and ARMv7 flush_cache_louis()/ flush_dcache_all()) code to be more efficient, and enable this errata workaround by default for ARMv7+SMP CPUs. This complements the Versatile Express fix above. - Rework ARMv7 context code for errata 430973, so that only Cortex A8 CPUs are impacted by the branch target buffer flush when this errata is enabled. Also update the help text to indicate that all r1p* A8 CPUs are impacted. - Switch ARM to the generic show_mem() implementation, it conveys all the information which we were already reporting. - Prevent slow timer sources being used for udelay() - timers running at less than 1MHz are not useful for this, and can cause udelay() to return immediately, without any wait. Using such a slow timer is silly. - VDSO support for 32-bit ARM, mainly for gettimeofday() using the ARM architected timer. - Perf support for Scorpion performance monitoring units" vdso semantic conflict fixed up as per linux-next. * 'for-linus' of git://ftp.arm.linux.org.uk/~rmk/linux-arm: (52 commits) ARM: update errata 430973 documentation to cover Cortex A8 r1p* ARM: ensure delay timer has sufficient accuracy for delays ARM: switch to use the generic show_mem() implementation ARM: proc-v7: avoid errata 430973 workaround for non-Cortex A8 CPUs ARM: enable ARM errata 643719 workaround by default ARM: cache-v7: optimise test for Cortex A9 r0pX devices ARM: cache-v7: optimise branches in v7_flush_cache_louis ARM: cache-v7: consolidate initialisation of cache level index ARM: cache-v7: shift CLIDR to extract appropriate field before masking ARM: cache-v7: use movw/movt instructions ARM: allow 16-bit instructions in ALT_UP() ARM: proc-arm94*.S: fix setup function ARM: vexpress: fix CPU hotplug with CT9x4 tile.

Jeff Kirsher says: ==================== Intel Wired LAN Driver Updates 2015-04-14 This series contains updates to fm10k only. Fixed transmit statistics which was actually using values from the receive ring, instead of the transmit ring. Fixed up spelling mistakes in code comments and resolved unused argument warnings. Added support for netconsole. Fixed up statistic reporting so that we are only reporting from actual queues as well as display PF only stats for just the PF and not the VF. Also fixed an issue that when returning virtualization queues from the VF back to the PF, we were retaining the VF rate limiter. Fixed up the driver to use a separate workqueue, which helps reduce and stabilize latency between scheduling the work in our interrupt and actually performing the work. Fixed a bug where the VF tried to set a multicast address before requesting the required xcast mode. Fix VF multicast update since VFs were being improperly added to the switch's mutlicast group. The error stems from the fact that incorrect arguments were passed to the update_mc_addr(). Thanks to Alex Duyck for the extensive review. ==================== Signed-off-by: David S.

However, it fixes a collision where dynamic and static busses request the same id. - driver bugfixes, cleanups" * 'i2c/for-next' of git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux: (52 commits) i2c: xlp9xx: Driver for Netlogic XLP9XX/5XX I2C controller of: Add vendor prefix 'netlogic' i2c: davinci: use ICPFUNC to toggle I2C as gpio for bus recovery i2c: davinci: use bus recovery infrastructure i2c: change input parameter to i2c_adapter for prepare/unprepare_recovery i2c: i2c-mux-gpio: remove error messages for probe deferrals i2c: jz4780: Add i2c bus controller driver for Ingenic JZ4780 i2c: dln2: set the device tree node of the adapter i2c: davinci: fixup wait_for_completion_timeout handling i2c: mpc: Fix ISR return value i2c: slave-eeprom: add more info when to increase the pointer i2c: slave: add documentation for i2c-slave-eeprom Documentation: i2c: describe the new slave mode i2c: slave: rework the slave API i2c: add support for the Digicolor I2C controller i2c: busses with dynamic ids should start after fixed ids for DT of: base: add function to get highest id of an alias stem i2c: designware: Suppress error message if platform_get_irq() < 0 i2c: mpc: assign the correct prescaler from SVR i2c: img-scb: fixup of wait_for_completion_timeout return handling ...

Pull pincontrol updates from Linus Walleij: "This is the bulk of pin control changes for the v4.1 development cycle. Nothing really exciting this time: we basically added a few new drivers and subdrivers and stabilized them in linux-next. Some cleanups too.
