      io_uring: protect cq_timeouts with timeout_lock · ea011ee1
      Pavel Begunkov authored
      Read cq_timeouts in io_flush_timeouts() only after taking the
      timeout_lock, as it's protected by it. There are many places where we
      also grab ->completion_lock, but for instance io_timeout_fn() doesn't
      and still modifies cq_timeouts.

      Pull EFI updates from Ard Biesheuvel:
       "Another fairly sizable pull request, by EFI subsystem standards.
      
        Most of the work was done by me, some of it in collaboration with the
        distro and bootloader folks (GRUB, systemd-boot), where the main focus
        has been on removing pointless per-arch differences in the way EFI
        boots a Linux kernel.
      
         - Refactor the zboot code so that it incorporates all the EFI stub
           logic, rather than calling the decompressed kernel as a EFI app.
      
         - Add support for initrd= command line option to x86 mixed mode.
      
         - Allow initrd= to be used with arbitrary EFI accessible file systems
           instead of just the one the kernel itself was loaded from.
      
         - Move some x86-only handling and manipulation of the EFI memory map
           into arch/x86, as it is not used anywhere else.
      
         - More flexible handling of any random seeds provided by the boot
           environment (i.e., systemd-boot) so that it becomes available much
           earlier during the boot.
      
         - Allow improved arch-agnostic EFI support in loaders, by setting a
           uniform baseline of supported features, and adding a generic magic
           number to the DOS/PE header. This should allow loaders such as GRUB
           or systemd-boot to reduce the amount of arch-specific handling
           substantially.
      
         - (arm64) Run EFI runtime services from a dedicated stack, and use it
           to recover from synchronous exceptions that might occur in the
           firmware code.
      
         - (arm64) Ensure that we don't allocate memory outside of the 48-bit
           addressable physical range.
      
         - Make EFI pstore record size configurable

      Pull clk driver updates from Stephen Boyd:
       "A pile of clk driver updates with a small tracepoint patch to the clk
        core this time around.
      
        The core framework is effectively unchanged, with the majority of the
        diff going to the Qualcomm clk driver directory because they added two
        3k line files that are almost all clk data (Abel Vesa from Linaro
        tried to shrink the number of lines down, but it doesn't seem to be
        possible without sacrificing readability).
      
        The second big driver this time around is the Rockchip rk3588 clk and
        reset unit, at _only_ 2.5k lines.
      
        Ignoring the big clk drivers from the familiar SoC vendors, there's
        just a bunch of little clk driver updates and fixes throughout here.
      
        It's the usual set of clk data fixups to describe proper parents, or
        add frequencies to frequency tables, or plug memory leaks when
        function calls fail. Also, some drivers are converted to use modern
        clk_hw APIs, which is always nice to see. And data is deduplicated,
        leading to a smaller kernel Image.
      
        Overall this batch has a larger collection of cleanups than it
        typically does. Maybe that means there are less new SoCs right now
        that need supporting, and the focus has shifted to quality and
        reliability. I can dream.
      
        New Drivers:
         - Frequency hopping controller hardware on MediaTek MT8186
         - Global clock controller for Qualcomm SM8550
         - Display clock controller for Qualcomm SC8280XP
         - RPMh clock controller for Qualcomm QDU1000 and QRU1000 SoCs
         - CPU PLL on MStar/SigmaStar SoCs
         - Support for the clock and reset unit of the Rockchip rk3588

         - Debugfs support for fractional divider clk
         - Make MxL's CGU driver secure compatible
         - Ingenic JZ4755 SoC clk support

        autovalidate these trees against strict schemas and it is paying off
        in lots of bugs found and ever prettier device trees. Sooner or later
        the transition will be complete, Krzysztof is fixing up all of the
        Qualcomm stuff, which is pretty voluminous.
      
        Core changes:
      
         - minor but nice and important documentation clean-ups
      
        New drivers:
      
         - subdriver for the Qualcomm SDM670 SoC
      
         - subdriver for the Intel Moorefield SoC
      
         - trivial support for the NXP Freescale i.MXRT1170 SoC
      
        Other changes and improvements
      
         - major clean-up of the Qualcomm pin control device tree bindings by
           Krzysztof
      
         - major header clean-up by Andy
      
         - some immutable irqchip clean-up for the Actions Semiconductor and
           Nuvoton drivers
      
         - GPIO helpers for The Cypress cy8c95x0 driver
      
         - bias handling in the Mediatek MT7986 driver
      
         - remove the unused pins-are-numbered concept that never flew"

       "A busy enough release, but not for the core which has only seen very
        small updates. The biggest addition is the readdition of support for
        detailed configuration of the timings around chip selects. That had
        been removed for lack of use but there's been applications found for
        it on Atmel systems. Otherwise the updates are mostly feature
        additions and cleanups to existing drivers.
      
        Summary:
      
         - Provide a helper for getting device match data in a way that
           abstracts away which firmware interface is being used.
      
         - Re-add the spi_set_cs_timing() API for detailed configuration of
           the timing around chip select and support it on Atmel.

      Pull regulator updates from Mark Brown:
       "Quite a quiet release for regulator, the diffstat is dominated by the
        I2C migration to probe_new() and the newly added MT6357 driver. We've
        just one framework addition and the rest is all new device support,
        fixes and cleanups.
      
        The framework addition is an API for requesting all regulators defined
        in DT, this isn't great practice but has reasonable applications when
        there is generic code handling devices on buses where the bus
        specification doesn't include power. The immediate application is MDIO
        but I believe there's others, it's another API that'll need an eye
        keeping on it for undesirable usage.

       "The biggest highlight is that the accel subsystem framework is merged.
        Hopefully for 6.3 we will be able to line up a driver to use it.
      
        In drivers land, i915 enables DG2 support by default now, and nouveau
        has a big stability refactoring and initial ampere support, AMD
        includes new hw IP support and should build on ARM again. There is
        also an ofdrm driver to take over offb on platforms it's used.
      
        Stuff outside my tree, the dma-buf patches hit a few places, the vc4
        firmware changes also do, and i915 has some interactions with MEI for

      Pull sound updates from Takashi Iwai:
       "This looks like a relatively calm development cycle; there have been
        only few changes in ALSA and ASoC core sides while we get lots of
        device-specific fixes and updates as usual. Most of commits are about
        ASoC, including Intel SOF/AVS and many device tree updates.
      
        Below are some highlights:
      
        Core:
         - Improvement in memalloc helper for fallback allocations
         - More cleanups of ASoC DAPM code
      
        ASoC:
         - Factoring out of mapping hw_params onto SoundWire configuration
         - The ever ongoing overhauls of the Intel DSP code continue,
           including support for loading libraries and probes with IPC4 on
           SOF.
         - Support for more sample formats on JZ4740
         - Lots of device tree conversions and fixups
         - Support for Allwinner D1, a range of AMD and Intel systems,
           Mediatek systems with multiple DMICs, Nuvoton NAU8318, NXP
           fsl_rpmsg and i.MX93, Qualcomm AudioReach Enable, MFC and SAL,
           RealTek RT1318 and Rockchip RK3588
      
        ALSA:
         - Addition of PCM kselftest; still minimalistic but can be extended
           in future
         - Fixes for corner-case XRUNs with USB-audio implicit feedback mode
         - Usual device-specific quirk updates for USB- and HD-audio
         - FireWire DICE updates
      
        This also contains a few cross-tree updates:
         - Some OMAP board file updates for removal of relevant OMAP platforms
         - A new I2C API update for I2C probe API adaption
         - A DRM update for the further hdmi-codec updates"

       - Fix use-after-free races due to missing resource cleanup during DM
         target destruction in DM targets: thin-pool, cache, integrity and
         clone.
      
       - Fix ABBA deadlocks in DM thin-pool and cache targets due to their use
         of a bufio client (that has a shrinker whose locking can cause the
         incorrect locking order).
      
       - Fix DM cache target to set its needs_check flag after first aborting
         the metadata (whereby using reset persistent-data objects to update
         the superblock with, otherwise the superblock update could be dropped
         due to aborting metadata). This was found with code-inspection when
         comparing with the equivalent in DM thinp code.
      
       - Fix DM thin-pool's presume to continue resuming the device even if
         the pool in is fail mode -- otherwise bios may never be failed up the
         IO stack (which will prevent resetting the thin-pool target via table
         reload)
      
       - Fix DM thin-pool's metadata to use proper btree root (from previous
         transaction) if metadata commit failed.
      
       - Add 'waitfor' module param to DM module (dm_mod) to allow dm-init to
         wait for the specified device before continuing with its DM target
         initialization.

       "The ususal set of driver fixes and improvements as well as several
        patches improving libata core in preparation of the introduction of
        the support for the command duration limits feature. In more details:
      
         - Define the missing COMPLETED sense key in scsi header (me)
      
         - Several patches to improve libata handling of the status of
           completed commands and the retry and sense data reported to the
           scsi layer for failed commands. In particular, this widen the
           support for NCQ autosense to all drives that support this feature
           instead of restricting this feature use to ZAC drives only (Niklas)
      
         - Cleanup of the pata_mpc52xx and sata_dwc_460ex drivers to remove
           the use of the deprecated NO_IRQ macro (Christophe)
      
         - Fix build dedependency on OF vs use of the of_match_ptr() macro to
           avoid build errors with the sata_gemini and pata_ftide010 drivers
           (me)
      
         - Some libata cleanups using the new helper function
           ata_port_is_frozen() (Niklas)
      
         - Improve internal command handling by not retrying commands that
           failed with a timeout (Niklas)
      
         - Remove code for several unused libata helper functions (from
           Niklas)
      
         - Remove the palmchip pata_bk3710 driver. A couple of other driver
           removal should come in through the arm tree pull request (from
           Arnd)
      
         - Remove unused variable and function in the sata_dwc_460ex driver
           and libata-sff code (Colin and Sergey)
      
         - Minor cleanup of the pata_ep93xx driver platform code (from
           Minghao)
      
         - Remove the unnecessary linux/msi.h include from the ahci driver

       - Always ensure proper ordering in case of CQ ring overflow, which then
         means we can remove some work-arounds for that (Dylan)
      
       - Support completion batching for multishot, greatly increasing the
         efficiency for those (Dylan)
      
       - Flag epoll/eventfd wakeups done from io_uring, so that we can easily
         tell if we're recursing into io_uring again.
      
         Previously, this would have resulted in repeated multishot
         notifications if we had a dependency there. That could happen if an
         eventfd was registered as the ring eventfd, and we multishot polled
         for events on it. Or if an io_uring fd was added to epoll, and
         io_uring had a multishot request for the epoll fd.

      Pull simple-xattr updates from Christian Brauner:
       "This ports the simple xattr infrastucture to rely on a simple rbtree
        protected by a read-write lock instead of a linked list protected by a
        spinlock.
      
        A while ago we received reports about scaling issues for filesystems
        using the simple xattr infrastructure that also support setting a
        larger number of xattrs. Specifically, cgroups and tmpfs.
      
        Both cgroupfs and tmpfs can be mounted by unprivileged users in
        unprivileged containers and root in an unprivileged container can set
        an unrestricted number of security.* xattrs and privileged users can
        also set unlimited trusted.* xattrs. A few more words on further that
        below. Other xattrs such as user.* are restricted for kernfs-based
        instances to a fairly limited number.
      
        As there are apparently users that have a fairly large number of
        xattrs we should scale a bit better. Using a simple linked list
        protected by a spinlock used for set, get, and list operations doesn't
        scale well if users use a lot of xattrs even if it's not a crazy
        number.
      
        Let's switch to a simple rbtree protected by a rwlock. It scales way
        better and gets rid of the perf issues some people reported. We
        originally had fancier solutions even using an rcu+seqlock protected
        rbtree but we had concerns about being to clever and also that
        deletion from an rbtree with rcu+seqlock isn't entirely safe.
      
        The rbtree plus rwlock is perfectly fine. By far the most common
        operation is getting an xattr. While setting an xattr is not and
        should be comparatively rare. And listxattr() often only happens when
        copying xattrs between files or together with the contents to a new
        file.
      
        Holding a lock across listxattr() is unproblematic because it doesn't
        list the values of xattrs. It can only be used to list the names of
        all xattrs set on a file. And the number of xattr names that can be
        listed with listxattr() is limited to XATTR_LIST_MAX aka 65536 bytes.
        If a larger buffer is passed then vfs_listxattr() caps it to
        XATTR_LIST_MAX and if more xattr names are found it will return
        -E2BIG. In short, the maximum amount of memory that can be retrieved
        via listxattr() is limited and thus listxattr() bounded.
      
        Of course, the API is broken as documented on xattr(7) already. While
        I have no idea how the xattr api ended up in this state we should
        probably try to come up with something here at some point. An iterator
        pattern similar to readdir() as an alternative to listxattr() or
        something else.
      
        Right now it is extremly strange that users can set millions of xattrs
        but then can't use listxattr() to know which xattrs are actually set.
        And it's really trivial to do:
      
      	for i in {1..1000000}; do setfattr -n security.$i -v $i ./file1; done
      
        And around 5000 xattrs it's impossible to use listxattr() to figure
        out which xattrs are actually set. So I have suggested that we try to
        limit the number of xattrs for simple xattrs at least. But that's a
        future patch and I don't consider it very urgent.
      
        A bonus of this port to rbtree+rwlock is that we shrink the memory
        consumption for users of the simple xattr infrastructure.
      
        This also adds kernel documentation to all the functions"

      Pull lsm updates from Paul Moore:
      
       - Improve the error handling in the device cgroup such that memory
         allocation failures when updating the access policy do not
         potentially alter the policy.
      
       - Some minor fixes to reiserfs to ensure that it properly releases
         LSM-related xattr values.
      
       - Update the security_socket_getpeersec_stream() LSM hook to take
         sockptr_t values.
      
         Previously the net/BPF folks updated the getsockopt code in the
         network stack to leverage the sockptr_t type to make it easier to
         pass both kernel and __user pointers, but unfortunately when they did
         so they didn't convert the LSM hook.
      
         While there was/is no immediate risk by not converting the LSM hook,
         it seems like this is a mistake waiting to happen so this patch
         proactively does the LSM hook conversion.
      
       - Convert vfs_getxattr_alloc() to return an int instead of a ssize_t
         and cleanup the callers. Internally the function was never going to
         return anything larger than an int and the callers were doing some
         very odd things casting the return value; this patch fixes all that
         and helps bring a bit of sanity to vfs_getxattr_alloc() and its
         callers.
      
       - More verbose, and helpful, LSM debug output when the system is booted
         with "lsm.debug" on the command line. There are examples in the
         commit description, but the quick summary is that this patch provides
         better information about which LSMs are enabled and the ordering in
         which they are processed.
      
       - General comment and kernel-doc fixes and cleanups.
