2019-04-12clk: imx: Fix PLL_1416X not rounding ratesLeonard Crestez1-1/+1
Code which initializes the "clk_init_data.ops" checks pll->rate_table before that field is ever assigned to so it always picks "clk_pll1416x_min_ops". This breaks dynamic rate rounding for features such as cpufreq. Fix by checking pll_clk->rate_table instead, here pll_clk refers to the constant initialization data coming from per-soc clk driver.

2019-04-12arm64: futex: Fix FUTEX_WAKE_OP atomic ops with non-zero result valueWill Deacon1-8/+8
Rather embarrassingly, our futex() FUTEX_WAKE_OP implementation doesn't explicitly set the return value on the non-faulting path and instead leaves it holding the result of the underlying atomic operation. This means that any FUTEX_WAKE_OP atomic operation which computes a non-zero value will be reported as having failed. Regrettably, I wrote the buggy code back in 2011 and it was upstreamed as part of the initial arm64 support in 2012. The reasons we appear to get away with this are: 1. FUTEX_WAKE_OP is rarely used and therefore doesn't appear to get exercised by futex() test applications 2. If the result of the atomic operation is zero, the system call behaves correctly 3. Prior to version 2.25, the only operation used by GLIBC set the futex to zero, and therefore worked as expected. From 2.25 onwards, FUTEX_WAKE_OP is not used by GLIBC at all. Fix the implementation by ensuring that the return value is either 0 to indicate that the atomic operation completed successfully, or -EFAULT if we encountered a fault when accessing the user mapping.

The exlcusion range limit register needs to contain the base-address of the last page that is part of the range, as bits 0-11 of this register are treated as 0xfff by the hardware for comparisons.

2019-04-12perf/core: Fix perf_event_disable_inatomic() racePeter Zijlstra2-11/+45
Thomas-Mich Richter reported he triggered a WARN()ing from event_function_local() on his s390. The problem boils down to: CPU-A CPU-B perf_event_overflow() perf_event_disable_inatomic() @pending_disable = 1 irq_work_queue(); sched-out event_sched_out() @pending_disable = 0 sched-in perf_event_overflow() perf_event_disable_inatomic() @pending_disable = 1; irq_work_queue(); // FAILS irq_work_run() perf_pending_event() if (@pending_disable) perf_event_disable_local(); // WHOOPS The problem exists in generic, but s390 is particularly sensitive because it doesn't implement arch_irq_work_raise(), nor does it call irq_work_run() from it's PMU interrupt handler (nor would that be sufficient in this case, because s390 also generates perf_event_overflow() from pmu::stop). Add to that the fact that s390 is a virtual architecture and (virtual) CPU-A can stall long enough for the above race to happen, even if it would self-IPI. Adding a irq_work_sync() to event_sched_in() would work for all hardare PMUs that properly use irq_work_run() but fails for software PMUs. Instead encode the CPU number in @pending_disable, such that we can tell which CPU requested the disable. This then allows us to detect the above scenario and even redirect the IPI to make up for the failed queue.

According to the NFSv4.2 spec if the input and output file is the same file, operation should fail with EINVAL. However, linux copy_file_range() system call has no such restrictions. Therefore, in such case let's return EOPNOTSUPP and allow VFS to fallback to doing do_splice_direct(). Also when copy_file_range is called on an NFSv4.0 or 4.1 mount (ie., a server that doesn't support COPY functionality), we also need to return EOPNOTSUPP and fallback to a regular copy.

2019-04-11NFS: Forbid setting AF_INET6 to "struct sockaddr_in"->sin_family.Tetsuo Handa1-1/+2
syzbot is reporting uninitialized value at rpc_sockaddr2uaddr() [1]. This is because syzbot is setting AF_INET6 to "struct sockaddr_in"->sin_family (which is embedded into user-visible "struct nfs_mount_data" structure) despite nfs23_validate_mount_data() cannot pass sizeof(struct sockaddr_in6) bytes of AF_INET6 address to rpc_sockaddr2uaddr(). Since "struct nfs_mount_data" structure is user-visible, we can't change "struct nfs_mount_data" to use "struct sockaddr_storage". Therefore, assuming that everybody is using AF_INET family when passing address via "struct nfs_mount_data"->addr, reject if its sin_family is not AF_INET.

2019-04-11nvmet: fix discover log page when offsets are usedKeith Busch4-25/+58
The nvme target hadn't been taking the Get Log Page offset parameter into consideration, and so has been returning corrupted log pages when offsets are used. Since many tools, including nvme-cli, split the log request to 4k, we've been breaking discovery log responses when more than 3 subsystems exist. Fix the returned data by internally generating the entire discovery log page and copying only the requested bytes into the user buffer. The command log page offset type has been modified to a native __le64 to make it easier to extract the value from a command.

2019-04-11nvme-fc: correct csn initialization and increments on errorJames Smart1-5/+15
This patch fixes a long-standing bug that initialized the FC-NVME cmnd iu CSN value to 1. Early FC-NVME specs had the connection starting with CSN=1. By the time the spec reached approval, the language had changed to state a connection should start with CSN=0. This patch corrects the initialization value for FC-NVME connections. Additionally, in reviewing the transport, the CSN value is assigned to the new IU early in the start routine. It's possible that a later dma map request may fail, causing the command to never be sent to the controller. Change the location of the assignment so that it is immediately prior to calling the lldd. Add a comment block to explain the impacts if the lldd were to additionally fail sending the command.

git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-linus ASoC: Fixes for v5.1 A few core fixes along with the driver specific ones, mainly fixing small issues that only affect x86 platforms for various reasons (their unusual machine enumeration mechanisms mainly, plus a fix for error handling in topology). There's some of the driver fixes that look larger than they are, like the hdmi-codec changes which resulted in an indentation change, and most of the other large changes are for new drivers like the STM32 changes.
2019-04-11mmc: sdhci-omap: Don't finish_mrq() on a command error during tuningFaiz Abbas1-0/+38
commit 5b0d62108b46 ("mmc: sdhci-omap: Add platform specific reset callback") skips data resets during tuning operation. Because of this, a data error or data finish interrupt might still arrive after a command error has been handled and the mrq ended. This ends up with a "mmc0: Got data interrupt 0x00000002 even though no data operation was in progress" error message. Fix this by adding a platform specific callback for sdhci_irq. Mark the mrq as a failure but wait for a data interrupt instead of calling finish_mrq().

Since commit 648e921888ad ("clk: x86: Stop marking clocks as CLK_IS_CRITICAL"), the pmc_plt_clocks of the Bay Trail SoC are unconditionally gated off. Unfortunately this will break systems where these clocks are used for external purposes beyond the kernel's knowledge. Fix it by implementing a system specific quirk to mark the necessary pmc_plt_clks as critical.

2019-04-10PCI: pciehp: Ignore Link State Changes after powering off a slotSergey Miroshnichenko1-0/+4
During a safe hot remove, the OS powers off the slot, which may cause a Data Link Layer State Changed event. The slot has already been set to OFF_STATE, so that event results in re-enabling the device, making it impossible to safely remove it. Clear out the Presence Detect Changed and Data Link Layer State Changed events when the disabled slot has settled down. It is still possible to re-enable the device if it remains in the slot after pressing the Attention Button by pressing it again. Fixes the problem that Micah reported below: an NVMe drive power button may not actually turn off the drive.

2019-04-10sparc64/pci_sun4v: fix ATU checks for large DMA masksChristoph Hellwig1-9/+11
Now that we allow drivers to always need to set larger than required DMA masks we need to be a little more careful in the sun4v PCI iommu driver to chose when to select the ATU support - a larger DMA mask can be set even when the platform does not support ATU, so we always have to check if it is avaiable before using it. Add a little helper for that and use it in all the places where we make ATU usage decisions based on the DMA mask.

2019-04-10IB/hfi1: Do not flush send queue in the TID RDMA second legKaike Wan1-23/+8
When a QP is put into error state, the send queue will be flushed. This mechanism is implemented in both the first and the second leg of the send engine. Since the second leg is only responsible for data transactions in the KDETH space for the TID RDMA WRITE request, it should not perform the flushing of the send queue. This patch removes the flushing function of the second leg, but still keeps the bailing out of the QP if it is put into error state.
