2014-06-25mac80211: split sched scan IEsDavid Spinadel12-32/+59
Split sched scan IEs to band specific and not band specific blocks. Common IEs blocks may be sent to the FW once per command, instead of per band. This allows optimization of size of the command, which may be required by some drivers (eg. iwlmvm with newer firmware version). As this changes the mac80211 API, update all drivers to use the new version correctly, even if they don't (yet) make use of the split data.

2014-06-25mac80211: support more than one band in scan requestDavid Spinadel11-11/+20
Some drivers (such as iwlmvm) can handle multiple bands in a single HW scan request. Add a HW flag to indicate that the driver support this. To hold the required data, create a separate structure for HW scan request that holds cfg scan request and data about different parts of the scan IEs. As this changes the mac80211 API, update all drivers using it to use the correct new function type/argument.

2014-06-14vxlan: use dev->needed_headroom instead of dev->hard_header_lenCong Wang1-4/+3
When we mirror packets from a vxlan tunnel to other device, the mirror device should see the same packets (that is, without outer header). Because vxlan tunnel sets dev->hard_header_len, tcf_mirred() resets mac header back to outer mac, the mirror device actually sees packets with outer headers Vxlan tunnel should set dev->needed_headroom instead of dev->hard_header_len, like what other ip tunnels do.

2014-06-13NVMe: Fix START_STOP_UNIT Scsi->NVMe translation.Dan McLeran1-7/+6
This patch contains several fixes for Scsi START_STOP_UNIT. The previous code did not account for signed vs. unsigned arithmetic which resulted in an invalid lowest power state caculation when the device only supports 1 power state. The code for Power Condition == 2 (Idle) was not following the spec. The spec calls for setting the device to specific power states, depending upon Power Condition Modifier, without accounting for the number of power states supported by the device. The code for Power Condition == 3 (Standby) was using a hard-coded '0' which is replaced with the macro POWER_STATE_0.

2014-06-13NVMe: Fix hot cpu notification dead lockKeith Busch1-10/+25
There is a potential dead lock if a cpu event occurs during nvme probe since it registered with hot cpu notification. This fixes the race by having the module register with notification outside of probe rather than have each device register. The actual work is done in a scheduled work queue instead of in the notifier since assigning IO queues has the potential to block if the driver creates additional queues.

git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm Pull more ACPI and power management updates from Rafael Wysocki: "These are fixups on top of the previous PM+ACPI pull request, regression fixes (ACPI hotplug, cpufreq ppc-corenet), other bug fixes (ACPI reset, cpufreq), new PM trace points for system suspend profiling and a copyright notice update. Specifics: - I didn't remember correctly that the Hans de Goede's ACPI video patches actually didn't flip the video.use_native_backlight default, although we had discussed that and decided to do that. Since I said we would do that in the previous PM+ACPI pull request, make that change for real now. - ACPI bus check notifications for PCI host bridges don't cause the bus below the host bridge to be checked for changes as they should because of a mistake in the ACPI-based PCI hotplug (ACPIPHP) subsystem that forgets to add hotplug contexts to PCI host bridge ACPI device objects. Create hotplug contexts for PCI host bridges too as appropriate. - Revert recent cpufreq commit related to the big.LITTLE cpufreq driver that breaks arm64 builds. - Fix for a regression in the ppc-corenet cpufreq driver introduced during the 3.15 cycle and causing the driver to use the remainder from do_div instead of the quotient. From Ed Swarthout. - Resets triggered by panic activate a BUG_ON() in vmalloc.c on systems where the ACPI reset register is located in memory address space. Fix from Randy Wright. - Fix for a problem with cpufreq governors that decisions made by them may be suboptimal due to the fact that deferrable timers are used by them for CPU load sampling. From Srivatsa S Bhat. - Fix for a problem with the Tegra cpufreq driver where the CPU frequency is temporarily switched to a "stable" level that is different from both the initial and target frequencies during transitions which causes udelay() to expire earlier than it should sometimes. From Viresh Kumar. - New trace points and rework of some existing trace points for system suspend/resume profiling from Todd Brandt. - Assorted cpufreq fixes and cleanups from Stratos Karafotis and Viresh Kumar. - Copyright notice update for suspend-and-cpuhotplug.txt from Srivatsa S Bhat" * tag 'pm+acpi-3.16-rc1-2' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: ACPI / hotplug / PCI: Add hotplug contexts to PCI host bridges PM / sleep: trace events for device PM callbacks cpufreq: cpufreq-cpu0: remove dependency on THERMAL and REGULATOR cpufreq: tegra: update comment for clarity cpufreq: intel_pstate: Remove duplicate CPU ID check cpufreq: Mark CPU0 driver with CPUFREQ_NEED_INITIAL_FREQ_CHECK flag PM / Documentation: Update copyright in suspend-and-cpuhotplug.txt cpufreq: governor: remove copy_prev_load from 'struct cpu_dbs_common_info' cpufreq: governor: Be friendly towards latency-sensitive bursty workloads PM / sleep: trace events for suspend/resume cpufreq: ppc-corenet-cpu-freq: do_div use quotient Revert "cpufreq: Enable big.LITTLE cpufreq driver on arm64" cpufreq: Tegra: implement intermediate frequency callbacks cpufreq: add support for intermediate (stable) frequencies ACPI / video: Change the default for video.use_native_backlight to 1 ACPI: Fix bug when ACPI reset register is implemented in system memory

2014-06-12target: Fix NULL pointer dereference for XCOPY in target_put_sess_cmdNicholas Bellinger1-0/+4
This patch fixes a NULL pointer dereference regression bug that was introduced with: commit 1e1110c43b1cda9fe77fc4a04835e460550e6b3c Author: Mikulas Patocka <mpatocka@redhat.com> Date: Sat May 17 06:49:22 2014 -0400 target: fix memory leak on XCOPY Now that target_put_sess_cmd() -> kref_put_spinlock_irqsave() is called with a valid se_cmd->cmd_kref, a NULL pointer dereference is triggered because the XCOPY passthrough commands don't have an associated se_session pointer. To address this bug, go ahead and checking for a NULL se_sess pointer within target_put_sess_cmd(), and call se_cmd->se_tfo->release_cmd() to release the XCOPY's xcopy_pt_cmd memory.

2014-06-12bnx2x: Enlarge the dorq threshold for VFsAriel Elior1-2/+4
A malicious VF might try to starve the other VFs & PF by creating contineous doorbell floods. In order to negate this, HW has a threshold of doorbells per client, which will stop the client doorbells from arriving if crossed. The threshold currently configured for VFs is too low - under extreme traffic scenarios, it's possible for a VF to reach the threshold and thus for its fastpath to stop working.
