2017-03-24IB/core: Protect against self-requeue of a cq work itemSagi Grimberg
We need to make sure that the cq work item does not run when we are destroying the cq. Unlike flush_work, cancel_work_sync protects against self-requeue of the work item (which we can do in ib_cq_poll_work).

2017-03-24i40iw: Receive netdev events post INET_NOTIFIER stateShiraz Saleem
Netdev notification events are de-registered only when all client iwdev instances are removed. If a single client is closed and re-opened, netdev events could arrive even before the Control Queue-Pair (CQP) is created, causing a NULL pointer dereference crash in i40iw_get_cqp_request. Fix this by allowing netdev event notification only after we have reached the INET_NOTIFIER state with respect to device initialization.

2017-03-24crypto: xts,lrw - fix out-of-bounds write after kmalloc failureEric Biggers
In the generic XTS and LRW algorithms, for input data > 128 bytes, a temporary buffer is allocated to hold the values to be XOR'ed with the data before and after encryption or decryption. If the allocation fails, the fixed-size buffer embedded in the request buffer is meant to be used as a fallback --- resulting in more calls to the ECB algorithm, but still producing the correct result. However, we weren't correctly limiting subreq->cryptlen in this case, resulting in pre_crypt() overrunning the embedded buffer. Fix this by setting subreq->cryptlen correctly.

The CCP registers its queues as channels capable of handling general DMA operations. The NTB driver will use DMA if directed, but as public channels can be reserved for use in asynchronous operations some channels should be held back as private. Since the public/private determination is handled at a device level, reserve the "other" (secondary) CCP channels as private. Add a module parameter that allows for override, to be applied to all channels on all devices.

This pdata pointer comes from the function call to padata_get_next(pd), which has in it the following block: next_queue = per_cpu_ptr(pd->pqueue, cpu); padata = NULL; reorder = &next_queue->reorder; if (!list_empty(&reorder->list)) { padata = list_entry(reorder->list.next, struct padata_priv, list); spin_lock(&reorder->lock); list_del_init(&padata->list); atomic_dec(&pd->reorder_objects); spin_unlock(&reorder->lock); pd->processed++; goto out; } out: return padata; I strongly suspect that the problem here is that two threads can race on reorder list. Even though the deletion is locked, call to list_entry is not locked, which means it's feasible that two threads pick up the same padata object and subsequently call list_add_tail on them at the same time. The fix is thus be hoist that lock outside of that block. Signed-off-by: Jason A.

Commit 52060836f79 ("dt-bindings: omap-rng: Document SafeXcel IP-76 device variant") update the omap_rng Device Tree binding to add support for the IP-76 variation of the IP. As part of this change, a "clocks" property was added, but is indicated as "Required", without indicated it's actually only required for some compatible strings.

2017-03-24x86/mm/KASLR: Exclude EFI region from KASLR VA space randomizationBaoquan He
Currently KASLR is enabled on three regions: the direct mapping of physical memory, vamlloc and vmemmap. However the EFI region is also mistakenly included for VA space randomization because of misusing EFI_VA_START macro and assuming EFI_VA_START < EFI_VA_END. (This breaks kexec and possibly other things that rely on stable addresses.) The EFI region is reserved for EFI runtime services virtual mapping which should not be included in KASLR ranges. In Documentation/x86/x86_64/mm.txt, we can see: ffffffef00000000 - fffffffeffffffff (=64 GB) EFI region mapping space EFI uses the space from -4G to -64G thus EFI_VA_START > EFI_VA_END, Here EFI_VA_START = -4G, and EFI_VA_END = -64G. Changing EFI_VA_START to EFI_VA_END in mm/kaslr.c fixes this problem.

Specifics: - Make intel_pstate use one set of global P-state limits in the active mode regardless of the scaling_governor settings for individual CPUs instead of switching back and forth between two of them in a way that is hard to control (Rafael Wysocki). - Drop a useless function from intel_pstate to prevent it from modifying the maximum supported frequency value unexpectedly which may confuse the cpufreq core (Rafael Wysocki). - Fix the cpufreq core to restore policy limits on CPU online so that the limits are not reset over system suspend/resume, among other things (Viresh Kumar). - Fix the initialization of the schedutil cpufreq governor to make the IO-wait boosting mechanism in it actually work on systems with one CPU per cpufreq policy (Rafael Wysocki). - Add a sanity check to the cpuidle core to prevent crashes from happening if the architecture code initialization fails to set up things as expected (Vaidyanathan Srinivasan)" * tag 'pm-4.11-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: cpufreq: Restore policy min/max limits on CPU online cpuidle: Validate cpu_dev in cpuidle_add_sysfs() cpufreq: intel_pstate: Fix policy data management in passive mode cpufreq: schedutil: Fix per-CPU structure initialization in sugov_start() cpufreq: intel_pstate: One set of global limits in active mode

2017-03-23PCI: thunder-pem: Add legacy firmware support for Cavium ThunderX host ↵Tomasz Nowicki
controller During early days of PCI quirks support, ThunderX firmware did not provide PNP0c02 node with PCI configuration space and PEM-specific register ranges. This means that for legacy FW we are not reserving these resources and cannot gather PEM-specific resources for further PEM initialization. To support already deployed legacy FW, calculate PEM-specific ranges and provide resources reservation as fallback scenario into PEM driver when we could not gather PEM reg base from ACPI tables.

2017-03-23Revert "i2c: mux: pca954x: Add ACPI support for pca954x"Andy Shevchenko
In ACPI world any ID should be carefully chosen and registered officially. The commit bbf9d262a147 seems did a wrong assumption because PCA is the registered PNP ID for "PHILIPS BU ADD ON CARD". I'm pretty sure this prefix has nothing to do with the driver in question. Moreover, newer ACPI specification has a support of _DSD method and special device IDs to allow drivers be enumerated via compatible string. The slight change to support this kind of enumeration will be added in sequential patch against pca954x.c. Revert the commit bbf9d262a147 for good.

2017-03-23KVM: kvm_io_bus_unregister_dev() should never failDavid Hildenbrand
No caller currently checks the return value of kvm_io_bus_unregister_dev(). This is evil, as all callers silently go on freeing their device. A stale reference will remain in the io_bus, getting at least used again, when the iobus gets teared down on kvm_destroy_vm() - leading to use after free errors. There is nothing the callers could do, except retrying over and over again. So let's simply remove the bus altogether, print an error and make sure no one can access this broken bus again (returning -ENOMEM on any attempt to access it).

Quoting from the Intel SDM, volume 3, section 28.3.3.4: Guidelines for Use of the INVEPT Instruction: If EPT was in use on a logical processor at one time with EPTP X, it is recommended that software use the INVEPT instruction with the "single-context" INVEPT type and with EPTP X in the INVEPT descriptor before a VM entry on the same logical processor that enables EPT with EPTP X and either (a) the "virtualize APIC accesses" VM-execution control was changed from 0 to 1; or (b) the value of the APIC-access address was changed. In the nested case, the burden falls on L1, unless L0 enables EPT in vmcs02 when L1 doesn't enable EPT in vmcs12.

The rationale for the breaking change was that upload_pm_data() potentially does blocking work in syscore_resume().
