There's a three-process deadlock involving shared/exclusive barriers and inverted lock orders in the directory readdir implementation. It's a pre-existing problem with lock ordering, exposed by the VFS parallelisation code. process 1 process 2 process 3 --------- --------- --------- readdir iolock(shared) get_leaf_dents iterate entries ilock(shared) map, lock and read buffer iunlock(shared) process entries in buffer ..... readdir iolock(shared) get_leaf_dents iterate entries ilock(shared) map, lock buffer <blocks> finish ->iterate_shared file_accessed() ->update_time start transaction ilock(excl) <blocks> ..... finishes processing buffer get next buffer ilock(shared) <blocks> And that's the deadlock. Fix this by dropping the current buffer lock in process 1 before trying to map the next buffer. This means we keep the lock order of ilock -> buffer lock intact and hence will allow process 3 to make progress and drop it's ilock(shared) once it is done.

Pull GPIO updates from Linus Walleij: "This is the bulk of GPIO changes for kernel cycle v4.7: Core infrastructural changes: - Support for natively single-ended GPIO driver stages. This means that if the hardware has registers to configure open drain or open source configuration, we use that rather than (as we did before) try to emulate it by switching the line to an input to get high impedance. This is also documented throughly in Documentation/gpio/driver.txt for those of you who did not understand one word of what I just wrote. - Start to do away with the unnecessarily complex and unitelligible ARCH_REQUIRE_GPIOLIB and ARCH_WANT_OPTIONAL_GPIOLIB, another evolutional artifact from the time when the GPIO subsystem was unmaintained. Archs can now just select GPIOLIB and be done with it, cleanups to arches will trickle in for the next kernel. Some minor archs ACKed the changes immediately so these are included in this pull request. - Advancing the use of the data pointer inside the GPIO device for storing driver data by switching the PowerPC, Super-H Unicore and a few other subarches or subsystem drivers in ALSA SoC, Input, serial, SSB, staging etc to use it. - The initialization now reads the input/output state of the GPIO lines, so that each GPIO descriptor knows - if this callback is implemented - whether the line is input or output. This also reflects nicely in userspace "lsgpio". - It is now possible to name GPIO producer names, line names, from the device tree. (Platform data has been supported for a while). I bet we will get a similar mechanism for ACPI one of those days. This makes is possible to get sensible producer names for e.g. GPIO rails in "lsgpio" in userspace. New drivers: - New driver for the Loongson1. - The XLP driver now supports Broadcom Vulcan ARM64. - The IT87 driver now supports IT8620 and IT8628. - The PCA953X driver now supports Galileo Gen2. Driver improvements: - MCP23S08 was switched to use the gpiolib irqchip helpers and now also suppors level-triggered interrupts. - 74x164 and RCAR now supports the .set_multiple() callback - AMDPT was converted to use generic GPIO. - TC3589x, TPS65218, SX150X, F7188X, MENZ127, VX855, WM831X, WM8994 support the new single ended callback for open drain and in some cases open source. - Implement the .get_direction() callback for a few more drivers like PL061, Xgene. Cleanups: - Paul Gortmaker combed through the drivers and de-modularized those who are not really modules. - Move the GPIO poweroff DT bindings to the power subdir where they belong. - Rename gpio-generic.c to gpio-mmio.c, which is much more to the point. That's what it is handling, nothing more, nothing less" * tag 'gpio-v4.7-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio: (126 commits) MIPS: do away with ARCH_[WANT_OPTIONAL|REQUIRE]_GPIOLIB gpio: zevio: make it explicitly non-modular gpio: timberdale: make it explicitly non-modular gpio: stmpe: make it explicitly non-modular gpio: sodaville: make it explicitly non-modular pinctrl: sh-pfc: Let gpio_chip.to_irq() return zero on error gpio: dwapb: Add ACPI device ID for DWAPB GPIO controller on X-Gene platforms gpio: dt-bindings: add wd,mbl-gpio bindings gpio: of: make it possible to name GPIO lines gpio: make gpiod_to_irq() return negative for NO_IRQ gpio: xgene: implement .get_direction() gpio: xgene: Enable ACPI support for X-Gene GFC GPIO driver gpio: tegra: Implement gpio_get_direction callback gpio: set up initial state from .get_direction() gpio: rename gpio-generic.c into gpio-mmio.c gpio: generic: fix GPIO_GENERIC_PLATFORM is set to module case gpio: dwapb: add gpio-signaled acpi event support gpio: dwapb: convert device node to fwnode gpio: dwapb: remove name from dwapb_port_property gpio/qoriq: select IRQ_DOMAIN ...

Ubifs internally uses special inodes for storing xattrs. Those inodes had NULL {get,set,remove}xattr inode operations before this change, so xattr operations on them would fail. The super block's s_xattr field would also apply to those special inodes. However, the inodes are not visible outside of ubifs, and so no xattr operations will ever be carried out on them anyway.

Windows clients set this flag via a set info (SET_FILE_DISPOSITION to set this flag) which properly checks if the directory is empty.

We currently do not check if any delimiter exists before the prefix path in cifs_compose_mount_options(). Consequently when building the devname using cifs_build_devname() we can end up with multiple delimiters separating the UNC and the prefix path. An issue was reported by the customer mounting a folder within a DFS share from a Netapp server which uses McAfee antivirus. We have narrowed down the cause to the use of double backslashes in the file name used to open the file. This was determined to be caused because of additional delimiters as a result of the bug. In addition to changes in cifs_build_devname(), we also fix cifs_parse_devname() to ignore any preceding delimiter for the prefix path. The problem was originally reported on RHEL 6 in RHEL bz 1252721. This is the upstream version of the fix. The fix was confirmed by looking at the packet capture of a DFS mount.

CIFS may be used as lower layer of overlayfs and accessing f_path.dentry can lead to a crash. Fix by replacing direct access of file->f_path.dentry with the file_dentry() accessor, which will always return a native object.

The current logic around the 'use_dac' module parameter prevents the r81969 driver from being loadable on 64-bit systems without any RAM below 4 GB when the parameter is left at its default value. So introduce a new default value -1 which indicates that 64-bit DMA should be enabled on sufficiently recent PCIe chips, i.e., versions RTL_GIGA_MAC_VER_18 or later. Explicit param values of 0 or 1 retain the existing behavior of unconditionally enabling/disabling 64-bit DMA on 64-bit architectures (i.e., regardless of the type and version of the chip) Since PCIe chips do not need to CPlusCmd Dual Address Cycle to be set, make that conditional on the device type as well.

If you compile without OF_MDIO support in an RGMII configuration, we fail to configure the dp83867 phy today by writing garbage into its configuration registers. On the other hand if you do compile with OF_MDIO and the phy gets loaded via device tree, you have to have the properties set in the device tree, otherwise we fail to load the driver and don't even attach the generic phy driver to the interface anymore. To make things slightly more consistent, make the rgmii configuration properties optional and allow a user to omit them in their device tree.

When CONFIG_OF_MDIO is configured as module, the #define for it really is CONFIG_OF_MDIO_MODULE, not CONFIG_OF_MDIO. So if we are compiling it as module, the dp83867 doesn't see that OF_MDIO was selected and doesn't read the dt rgmii parameters. The fix is simple: Use IS_ENABLED(). It checks for both - module as well as compiled in code. Signed-off-by: NAlexander Graf <agraf@suse.de> Signed-off-by: NDavid S. Miller <davem@davemloft.net>

Merge tag 'qcom-soc-for-4.7-2' into net-next This merges the Qualcomm SOC tree with the net-next, solving the merge conflict in the SMD API between the two.

In the current implementation of ARM64 eBPF JIT, R23 and R24 are used for tmp registers, which are callee-saved registers. This leads to variable size of JIT prologue and epilogue. The latest blinding constant change prefers to constant size of prologue and epilogue. AAPCS reserves R9 ~ R15 for temp registers which not need to be saved/restored during function call. So, replace R23 and R24 to R10 and R11, and remove tmp_used flag to save 2 instructions for some jited BPF program.
