      io_uring: dont overlap internal and user req flags · dddca226
      Pavel Begunkov authored
      CQE flags take one byte that we store in req->flags together with other
      REQ_F_* internal flags. CQE flags are copied directly into req and then
      verified that requires some handling on failures, e.g. to make sure that
      that copy doesn't set some of the internal flags.
      
      Move all internal flags to take bits after the first byte, so we don't
      need extra handling and make it safer overall.

       "The x86 MM changes in this cycle were:
      
         - Implement concurrent TLB flushes, which overlaps the local TLB
           flush with the remote TLB flush.
      
           In testing this improved sysbench performance measurably by a
           couple of percentage points, especially if TLB-heavy security
           mitigations are active.

      Linus Torvalds authored
      Pull xfs updates from Darrick Wong:
       "The notable user-visible addition this cycle is ability to remove
        space from the last AG in a filesystem. This is the first of many
        changes needed for full-fledged support for shrinking a filesystem.
        Still needed are (a) the ability to reorganize files and metadata away
        from the end of the fs; (b) the ability to remove entire allocation
        groups; (c) shrink support for realtime volumes; and (d) thorough
        testing of (a-c).
      
        There are a number of performance improvements in this code drop: Dave
        streamlined various parts of the buffer logging code and reduced the
        cost of various debugging checks, and added the ability to pre-create
        the xattr structures while creating files. Brian eliminated
        transaction reservations that were being held across writeback (thus
        reducing livelock potential.
      
        Other random pieces: Pavel fixed the repetitve warnings about
        deprecated mount options, I fixed online fsck to behave itself when a
        readonly remount comes in during scrub, and refactored various other
        parts of that code, Christoph contributed a lot of refactoring this
        cycle. The xfs_icdinode structure has been absorbed into the (incore)
        xfs_inode structure, and the format and flags handling around
        xfs_inode_fork structures has been simplified. Chandan provided a
        number of fixes for extent count overflow related problems that have
        been shaken out by debugging knobs added during 5.12.
      
        Summary:
      
         - Various minor fixes in online scrub.
      
         - Prevent metadata files from being automatically inactivated.
      
         - Validate btree heights by the computed per-btree limits.
      
         - Don't warn about remounting with deprecated mount options.
      
         - Initialize attr forks at create time if we suspect we're going to
           need to store them.
      
         - Reduce memory reallocation workouts in the logging code.
      
         - Fix some theoretical math calculation errors in logged buffers that
           span multiple discontig memory ranges but contiguous ondisk
           regions.
      
         - Speedups in dirty buffer bitmap handling.
      
         - Make type verifier functions more inline-happy to reduce overhead.
      
         - Reduce debug overhead in directory checking code.
      
         - Many many typo fixes.
      
         - Begin to handle the permanent loss of the very end of a filesystem.
      
         - Fold struct xfs_icdinode into xfs_inode.
      
         - Deprecate the long defunct BMV_IF_NO_DMAPI_READ from the bmapx
           ioctl.
      
         - Remove a broken directory block format check from online scrub.
      
         - Fix a bug where we could produce an unnecessarily tall data fork
           btree when creating an attr fork.
      
         - Fix scrub and readonly remounts racing.
      
         - Fix a writeback ioend log deadlock problem by dropping the behavior
           where we could preallocate a setfilesize transaction.
      
         - Fix some bugs in the new extent count checking code.
      
         - Fix some bugs in the attr fork preallocation code.

      Pull clk updates from Stephen Boyd:
       "Here's a collection of largely clk driver updates. The usual suspects
        are here: i.MX, Qualcomm, Renesas, Allwinner, Samsung, and Rockchip,
        but it feels pretty light on commits.
      
        There's only one real commit to the framework core and that's to
        consolidate code. Otherwise the diffstat is dominated by many Qualcomm
        clk driver patches that modernize the driver for the proper way of
        speciying clk parents. That's shifting data around, which could subtly
        break things so I'll be on the lookout for fixes.
      
        New Drivers:
         - Proper clk driver for Mediatek MT7621 SoCs
         - Support for the clock controller on the new Rockchip rk3568
      
        Updates:
         - Simplify Zynq Kconfig dependencies
         - Use clk_hw pointers in socfpga driver
         - Cleanup parent data in qcom clk drivers

         should/could be made generic at some point.
      
       - Removal of the need to have a manager thread for each ring. The
         manager threads only job was checking and creating new io-threads as
         needed, instead we handle this from the queue path.
      
       - Allow SQPOLL without CAP_SYS_ADMIN or CAP_SYS_NICE. Since 5.12, this
         thread is "just" a regular application thread, so no need to restrict
         use of it anymore.
      
       - Cleanup of how internal async poll data lifetime is managed.
      
       - Fix for syzbot reported crash on SQPOLL cancelation.
      
       - Make buffer registration more like file registrations, which includes
         flexibility in avoiding full set unregistration and re-registration.
      
       - Fix for io-wq affinity setting.
      
       - Be a bit more defensive in task->pf_io_worker setup.
      
       - Various SQPOLL fixes.
      
       - Cleanup of SQPOLL creds handling.

       - Clean up SCHED_DEBUG: move the decades old mess of sysctl, procfs and
         debugfs interfaces to a unified debugfs interface.
      
       - Signals: Allow caching one sigqueue object per task, to improve
         performance & latencies.
      
       - Improve newidle_balance() irq-off latencies on systems with a large
         number of CPU cgroups.
      
       - Improve energy-aware scheduling
      
       - Improve the PELT metrics for certain workloads
      
       - Reintroduce select_idle_smt() to improve load-balancing locality -
         but without the previous regressions
      
       - Add 'scheduler latency debugging': warn after long periods of pending
         need_resched. This is an opt-in feature that requires the enabling of
         the LATENCY_WARN scheduler feature, or the use of the
         resched_latency_warn_ms=xx boot parameter.
      
       - CPU hotplug fixes for HP-rollback, and for the 'fail' interface. Fix
         remaining balance_push() vs. hotplug holes/races
      
       - PSI fixes, plus allow /proc/pressure/ files to be written by
         CAP_SYS_RESOURCE tasks as well
      
       - Fix/improve various load-balancing corner cases vs. capacity margins

      Pull perf event updates from Ingo Molnar:
      
       - Improve Intel uncore PMU support:
      
           - Parse uncore 'discovery tables' - a new hardware capability
             enumeration method introduced on the latest Intel platforms. This
             table is in a well-defined PCI namespace location and is read via
             MMIO. It is organized in an rbtree.
      
             These uncore tables will allow the discovery of standard counter
             blocks, but fancier counters still need to be enumerated
             explicitly.
      
           - Add Alder Lake support
      
           - Improve IIO stacks to PMON mapping support on Skylake servers
      
       - Add Intel Alder Lake PMU support - which requires the introduction of
         'hybrid' CPUs and PMUs. Alder Lake is a mix of Golden Cove ('big')
         and Gracemont ('small' - Atom derived) cores.
      
         The CPU-side feature set is entirely symmetrical - but on the PMU
         side there's core type dependent PMU functionality.
      
       - Reduce data loss with CPU level hardware tracing on Intel PT / AUX
         profiling, by fixing the AUX allocation watermark logic.
      
       - Improve ring buffer allocation on NUMA systems
      
       - Put 'struct perf_event' into their separate kmem_cache pool
      
       - Add support for synchronous signals for select perf events. The
         immediate motivation is to support low-overhead sampling-based race
         detection for user-space code. The feature consists of the following
         main changes:
      
           - Add thread-only event inheritance via
             perf_event_attr::inherit_thread, which limits inheritance of
             events to CLONE_THREAD.
      
           - Add the ability for events to not leak through exec(), via
             perf_event_attr::remove_on_exec.
      
           - Allow the generation of SIGTRAP via perf_event_attr::sigtrap,
             extend siginfo with an u64 ::si_perf, and add the breakpoint
             information to ::si_addr and ::si_perf if the event is
             PERF_TYPE_BREAKPOINT.
      
         The siginfo support is adequate for breakpoints right now - but the
         new field can be used to introduce support for other types of
         metadata passed over siginfo as well.
      
       - Misc fixes, cleanups and smaller updates.

      Pull printk updates from Petr Mladek:
      
       - Stop synchronizing kernel log buffer readers by logbuf_lock. As a
         result, the access to the buffer is fully lockless now.
      
         Note that printk() itself still uses locks because it tries to flush
         the messages to the console immediately. Also the per-CPU temporary
         buffers are still there because they prevent infinite recursion and
         serialize backtraces from NMI. All this is going to change in the
         future.
      
       - kmsg_dump API rework and cleanup as a side effect of the logbuf_lock
         removal.
      
       - Make bstr_printf() aware that %pf and %pF formats could deference the
         given pointer.
      
       - Show also page flags by %pGp format.

      Pull kgdb updates from Daniel Thompson:
       "Exclusively tidy ups this cycle. Most of them are thanks to Sumit Garg
        and, as it happens, the clean ups do result in a slight increase in
        the line count. This is due to registering kdb commands using data
        structures rather than function calls which, in turn, simplifies the
        memory management during command registration.
      
        In addition to changes to command registration we also have some dead
        code removal, a clearer implementation of environment variable
        handling and a typo fix"

      Pull s390 updates from Heiko Carstens:
      
       - fix buffer size for in-kernel disassembler for ebpf programs.
      
       - fix two memory leaks in zcrypt driver.
      
       - expose PCI device UID as index, including an indicator if the uid is
         unique.
      
       - remove some oprofile leftovers.
      
       - improve stack unwinder tests.
      
       - don't use gcc atomic builtins anymore, just like all other
         architectures. Even though I'm sure the current code is ok, I totally
         dislike that s390 is the only architecture being special here;
         especially considering that there was a lengthly discussion about
         this topic and the outcome was not to use the builtins. Therefore
         open-code atomic ops again with inline assembly and switch to gcc
         builtins as soon as other architectures are doing.
      
       - couple of other changes to atomic and cmpxchg, and use
         atomic-instrumented.h for KASAN.
      
       - separate zbus creation, registration, and scanning in our PCI code
         which allows for cleaner and easier handling.
      
       - a rather large change to the vfio-ap code to fix circular locking
         dependencies when updating crypto masks.
      
       - move QAOB handling from qdio layer down to drivers.
      
       - add CRW inject facility to common I/O layer. This adds debugs files
         which allow to generate artificial events from user space for testing
         purposes.
      
       - increase SCLP console line length from 80 to 320 characters to avoid
         odd wrapped lines.
      
       - add protected virtualization guest and host indication files, which
         indicate either that a guest is running in pv mode or if the
         hypervisor is capable of starting pv guests.
      
       - various other small fixes and improvements all over the place.
