        There's also a refresh of the shareed config files (multi_v* on
        32-bit, and defconfig on 64-bit), to avoid conflicts when we get new

      pipe: fix incorrect caching of pipe state over pipe_wait() · ec057595
      Linus Torvalds authored
      Similarly to commit 8f868d68 ("pipe: Fix missing mask update after
      pipe_wait()") this fixes a case where the pipe rewrite ended up caching
      the pipe state incorrectly over a pipe lock drop event.
      
      It wasn't quite as obvious, because you needed to splice data from a
      pipe to a file, which is a fairly unusual operation, but it's completely
      wrong.
      
      Make sure we load the pipe head/tail/size information only after we've
      waited for there to be data in the pipe.
      
      While in that file, also make one of the splice helper functions use the
      canonical arghument order for pipe_empty().  That's syntactic - pipe
      emptiness is just that head and tail are equal, and thus mixing up head
      and tail doesn't really matter.  It's still wrong, though.

       "I wasn't expecting this to be so big, and if I was, I would have used
        separate branches for this. Going forward I'll be doing separate
        branches for the current tree, just like for the next kernel version
        tree. In any case, this contains:
      
         - Series from Christoph that fixes an inherent race condition with

         - Fix for io_uring creds allocation failure handling (me)
      
         - io_uring -ERESTARTSYS send/recvmsg fix (me)
      
         - Series that fixes the need for applications to retain state across
           async request punts for io_uring. This one is a bit larger than I
           would have hoped, but I think it's important we get this fixed for
           5.5.
      
         - connect(2) improvement for io_uring, handling EINPROGRESS instead
           of having applications needing to poll for it (me)
      
         - Have io_uring use a hash for poll requests instead of an rbtree.
           This turned out to work much better in practice, so I think we
           should make the switch now. For some workloads, even with a fair
           amount of cancellations, the insertion sort is just too expensive.
           (me)
      
         - Various little io_uring fixes (me, Jackie, Pavel, LimingWu)
      
         - Fix for brd unaligned IO, and a warning for the future (Ming)
      
         - Fix for a bio integrity data leak (Justin)
      
         - bvec_iter_advance() improvement (Pavel)
      
         - Xen blkback page unmap fix (SeongJae)

      Pull vfs d_inode/d_flags memory ordering fixes from Al Viro:
       "Fallout from tree-wide audit for ->d_inode/->d_flags barriers use.
        Basically, the problem is that negative pinned dentries require
        careful treatment - unless ->d_lock is locked or parent is held at
        least shared, another thread can make them positive right under us.
      
        Most of the uses turned out to be safe - the main surprises as far as
        filesystems are concerned were
      
         - race in dget_parent() fastpath, that might end up with the caller
           observing the returned dentry _negative_, due to insufficient
           barriers. It is positive in memory, but we could end up seeing the
           wrong value of ->d_inode in CPU cache. Fixed.
      
         - manual checks that result of lookup_one_len_unlocked() is positive
           (and rejection of negatives). Again, insufficient barriers (we
           might end up with inconsistent observed values of ->d_inode and
           ->d_flags). Fixed by switching to a new primitive that does the
           checks itself and returns ERR_PTR(-ENOENT) instead of a negative
           dentry. That way we get rid of boilerplate converting negatives
           into ERR_PTR(-ENOENT) in the callers and have a single place to
           deal with the barrier-related mess - inside fs/namei.c rather than
           in every caller out there.
      
        The guts of pathname resolution *do* need to be careful - the race
        found by Ritesh is real, as well as several similar races.
        Fortunately, it turns out that we can take care of that with fairly
        local changes in there.
      
        The tree-wide audit had not been fun, and I hate the idea of repeating
        it. I think the right approach would be to annotate the places where
        we are _not_ guaranteed ->d_inode/->d_flags stability and have sparse
        catch regressions. But I'm still not sure what would be the least
        invasive way of doing that and it's clearly the next cycle fodder"

      ARM: multi_v7_defconfig: Restore debugfs support · 18977008
      Commit fd7d58f0 ("ARM: multi_v7_defconfig: renormalize based on recent
      additions") removed explicit enable line for CONFIG_DEBUG_FS, because
      that feature has been selected by other enabled options: CONFIG_TRACING,
      which were enabled by CONFIG_PERF_EVENTS.
      
      In meantime, commit 0e4a459f ("tracing: Remove unnecessary DEBUG_FS
      dependency") removed the dependency between CONFIG_DEBUG_FS and
      CONFIG_TRACING, so CONFIG_DEBUG_FS is no longer enabled in default builds.
      
      Enable it again explicitly, as debugfs support is essential for various
      automated testing tools.

      arm64: ftrace: fix ifdeffery · 70927d02
      Mark Rutland authored
      When I tweaked the ftrace entry assembly in commit:
      
        3b23e499 ("arm64: implement ftrace with regs")
      
      ... my ifdeffery tweaks left ftrace_graph_caller undefined for
      CONFIG_DYNAMIC_FTRACE && CONFIG_FUNCTION_GRAPH_TRACER when ftrace is
      based on mcount.
      
      The kbuild test robot reported that this issue is detected at link time:
      
      | arch/arm64/kernel/entry-ftrace.o: In function `skip_ftrace_call':
      | arch/arm64/kernel/entry-ftrace.S:238: undefined reference to `ftrace_graph_caller'

      | `ftrace_graph_caller'
      
      This patch fixes the ifdeffery so that the mcount version of
      ftrace_graph_caller doesn't depend on CONFIG_DYNAMIC_FTRACE. At the same
      time, a redundant #else is removed from the ifdeffery for the
      patchable-function-entry version of ftrace_graph_caller.

      arm64: KVM: Invoke compute_layout() before alternatives are applied · 0492747c

      compute_layout() is invoked as part of an alternative fixup under
      stop_machine(). This function invokes get_random_long() which acquires a
      sleeping lock on -RT which can not be acquired in this context.
      
      Rename compute_layout() to kvm_compute_layout() and invoke it before
      stop_machine() applies the alternatives. Add a __init prefix to
      kvm_compute_layout() because the caller has it, too (and so the code can be
      discarded after boot).

      arm64: Validate tagged addresses in access_ok() called from kernel threads · df325e05
      Catalin Marinas authored
      __range_ok(), invoked from access_ok(), clears the tag of the user
      address only if CONFIG_ARM64_TAGGED_ADDR_ABI is enabled and the thread
      opted in to the relaxed ABI. The latter sets the TIF_TAGGED_ADDR thread
      flag. In the case of asynchronous I/O (e.g. io_submit()), the
      access_ok() may be called from a kernel thread. Since kernel threads
      don't have TIF_TAGGED_ADDR set, access_ok() will fail for valid tagged
      user addresses. Example from the ffs_user_copy_worker() thread:
      
      	use_mm(io_data->mm);
      	ret = ffs_copy_to_iter(io_data->buf, ret, &io_data->data);
      	unuse_mm(io_data->mm);
      
      Relax the __range_ok() check to always untag the user address if called
      in the context of a kernel thread. The user pointers would have already
      been checked via aio_setup_rw() -> import_{single_range,iovec}() at the
      time of the asynchronous I/O request.

      __arch_get_hw_counter() should check clock_mode to see if it can access
      CNTVCT. With the conversion to unified vDSO this check has been left out.
      
      This causes on imx v6 and v7 (imx_v6_v7_defconfig) and other platforms to
      hang at boot during the execution of the init process as per below:

      ARM: 8943/1: Fix topology setup in case of CPU hotplug for CONFIG_SCHED_MC · ff98a5f6
      Dietmar Eggemann authored
      Commit ca74b316 ("arm: Use common cpu_topology structure and
      functions.") changed cpu_coregroup_mask() from the ARM32 specific
      implementation in arch/arm/include/asm/topology.h to the one shared
      with ARM64 and RISCV in drivers/base/arch_topology.c.
      
      Currently on ARM32 (TC2 w/ CONFIG_SCHED_MC) the task scheduler setup
      code (w/ CONFIG_SCHED_DEBUG) shows this during CPU hotplug:
      
        ERROR: groups don't span domain->span
      
      It happens to CPUs of the cluster of the CPU which gets hot-plugged
      out on scheduler domain MC.
      
      Turns out that the shared cpu_coregroup_mask() requires that the
      hot-plugged CPU is removed from the core_sibling mask via
      remove_cpu_topology(). Otherwise the 'is core_sibling subset of
      cpumask_of_node()' doesn't work. In this case the task scheduler has to
      deal with cpumask_of_node instead of core_sibling which is wrong on
      scheduler domain MC.
      
      e.g. CPU3 hot-plugged out on TC2 [cluster0: 0,3-4 cluster1: 1-2]:
      
        cpu_coregroup_mask(): CPU3 cpumask_of_node=0-2,4 core_sibling=0,3-4
                                                                        ^
      should be:
      
        cpu_coregroup_mask(): CPU3 cpumask_of_node=0-2,4 core_sibling=0,4
      
      Add remove_cpu_topology() to __cpu_disable() to remove the CPU from the
      topology masks in case of a CPU hotplug out operation.
      
      At the same time tweak store_cpu_topology() slightly so it will call
      update_siblings_masks() in case of CPU hotplug in operation via
      secondary_start_kernel()->smp_store_cpu_info().
      
      This aligns the ARM32 implementation with the ARM64 one.
      
      Guarding remove_cpu_topology() with CONFIG_GENERIC_ARCH_TOPOLOGY is
      necessary since some Arm32 defconfigs (aspeed_g5_defconfig,
      milbeaut_m10v_defconfig, spear13xx_defconfig) specify an explicit
      
       # CONFIG_ARM_CPU_TOPOLOGY is not set
      
      w/ ./arch/arm/Kconfig: select GENERIC_ARCH_TOPOLOGY if ARM_CPU_TOPOLOGY

      Merge two fixes for the pipe rework from David Howells:
       "Here are a couple of patches to fix bugs syzbot found in the pipe
        changes:
      
         - An assertion check will sometimes trip when polling a pipe because
           the ring size and indices used are approximate and may be being
           changed simultaneously.
      
           An equivalent approximate calculation was done previously, but
           without the assertion check, so I've just dropped the check. To
           make it accurate, the pipe mutex would need to be taken or the spin
           lock could be used - but usage of the spinlock would need to be

      pipe: Fix missing mask update after pipe_wait() · 8f868d68
      David Howells authored
      Fix pipe_write() to not cache the ring index mask and max_usage as their
      values are invalidated by calling pipe_wait() because the latter
      function drops the pipe lock, thereby allowing F_SETPIPE_SZ change them.
      Without this, pipe_write() may subsequently miscalculate the array
      indices and pipe fullness, leading to an oops like the following:

      pipe: Remove assertion from pipe_poll() · 8c7b8c34
      David Howells authored
      An assertion check was added to pipe_poll() to make sure that the ring
      occupancy isn't seen to overflow the ring size.  However, since no locks
      are held when the three values are read, it is possible for F_SETPIPE_SZ
      to intervene and muck up the calculation, thereby causing the oops.
      
      Fix this by simply removing the assertion and accepting that the
      calculation might be approximate.
      
      Note that the previous code also had a similar issue, though there was
      no assertion check, since the occupancy counter and the ring size were
      not read with a lock held, so it's possible that the poll check might
      have malfunctioned then too.
      
      Also wake up all the waiters so that they can reissue their checks if
      there was a competing read or write.
      
      Fixes: 8cefc107 ("pipe: Use head and tail pointers for the ring, not cursor and length")
