      NFS/flexfiles: Use the correct TCP timeout for flexfiles I/O · 68f46159
      Trond Myklebust authored
      Fix a typo where we're confusing the default TCP retrans value
      (NFS_DEF_TCP_RETRANS) for the default TCP timeout value.

      SUNRPC: Fix up calculation of client message length · 7e3d3620
      Trond Myklebust authored
      In the case where a record marker was used, xs_sendpages() needs
      to return the length of the payload + record marker so that we
      operate correctly in the case of a partial transmission.
      When the callers check return value, they therefore need to
      take into account the record marker length.

      Pull pidfd fixes from Christian Brauner:
       "Userspace tools and libraries such as strace or glibc need a cheap and
        reliable way to tell whether CLONE_PIDFD is supported. The easiest way
        is to pass an invalid fd value in the return argument, perform the
        syscall and verify the value in the return argument has been changed
        to a valid fd.
      
        However, if CLONE_PIDFD is specified we currently check if pidfd == 0
        and return EINVAL if not.
      
        The check for pidfd == 0 was originally added to enable us to abuse
        the return argument for passing additional flags along with
        CLONE_PIDFD in the future.
      
        However, extending legacy clone this way would be a terrible idea and
        with clone3 on the horizon and the ability to reuse CLONE_DETACHED
        with CLONE_PIDFD there's no real need for this clutch. So remove the
        pidfd == 0 check and help userspace out.
      
        Also, accordig to Al, anon_inode_getfd() should only be used past the
        point of no failure and ksys_close() should not be used at all since
        it is far too easy to get wrong. Al's motto being "basically, once
        it's in descriptor table, it's out of your control". So Al's patch
        switches back to what we already had in v1 of the original patchset
        and uses a anon_inode_getfile() + put_user() + fd_install() sequence
        in the success path and a fput() + put_unused_fd() in the failure
        path.
      
        The other two changes should be trivial"

      Pull AFS fixes from David Howells:
       "The in-kernel AFS client has been undergoing testing on opendev.org on
        one of their mirror machines. They are using AFS to hold data that is
        then served via apache, and Ian Wienand had reported seeing oopses,
        spontaneous machine reboots and updates to volumes going missing. This
        patch series appears to have fixed the problem, very probably due to
        patch (2), but it's not 100% certain.
      
        (1) Fix the printing of the "vnode modified" warning to exclude checks
            on files for which we don't have a callback promise from the
            server (and so don't expect the server to tell us when it
            changes).
      
            Without this, for every file or directory for which we still have
            an in-core inode that gets changed on the server, we may get a
            message logged when we next look at it. This can happen in bulk
            if, for instance, someone does "vos release" to update a R/O
            volume from a R/W volume and a whole set of files are all changed
            together.
      
            We only really want to log a message if the file changed and the
            server didn't tell us about it or we failed to track the state
            internally.
      
        (2) Fix accidental corruption of either afs_vlserver struct objects or
            the the following memory locations (which could hold anything).
            The issue is caused by a union that points to two different
            structs in struct afs_call (to save space in the struct). The call
            cleanup code assumes that it can simply call the cleanup for one
            of those structs if not NULL - when it might be actually pointing
            to the other struct.
      
            This means that every Volume Location RPC op is going to corrupt
            something.
      
        (3) Fix an uninitialised spinlock. This isn't too bad, it just causes
            a one-off warning if lockdep is enabled when "vos release" is
            called, but the spinlock still behaves correctly.
      
        (4) Fix the setting of i_block in the inode. This causes du, for
            example, to produce incorrect results, but otherwise should not be
            dangerous to the kernel"

      ceph: fix ceph_mdsc_build_path to not stop on first component · d6b8bd67
      Jeff Layton authored
      When ceph_mdsc_build_path is handed a positive dentry, it will return a
      zero-length path string with the base set to that dentry.  This is not
      what we want.  Always include at least one path component in the string.
      
      ceph_mdsc_build_path has behaved this way for a long time but it didn't

      pinctrl: mediatek: Update cur_mask in mask/mask ops · 9d957a95
      Nicolas Boichat authored
      During suspend/resume, mtk_eint_mask may be called while
      wake_mask is active. For example, this happens if a wake-source
      with an active interrupt handler wakes the system:
      irq/pm.c:irq_pm_check_wakeup would disable the interrupt, so
      that it can be handled later on in the resume flow.
      
      However, this may happen before mtk_eint_do_resume is called:
      in this case, wake_mask is loaded, and cur_mask is restored
      from an older copy, re-enabling the interrupt, and causing
      an interrupt storm (especially for level interrupts).
      
      Step by step, for a line that has both wake and interrupt enabled:
       1. cur_mask[irq] = 1; wake_mask[irq] = 1; EINT_EN[irq] = 1 (interrupt
          enabled at hardware level)
       2. System suspends, resumes due to that line (at this stage EINT_EN
          == wake_mask)
       3. irq_pm_check_wakeup is called, and disables the interrupt =>
          EINT_EN[irq] = 0, but we still have cur_mask[irq] = 1
       4. mtk_eint_do_resume is called, and restores EINT_EN = cur_mask, so
          it reenables EINT_EN[irq] = 1 => interrupt storm as the driver
          is not yet ready to handle the interrupt.
      
      This patch fixes the issue in step 3, by recording all mask/unmask
      changes in cur_mask. This also avoids the need to read the current
      mask in eint_do_suspend, and we can remove mtk_eint_chip_read_mask
      function.
      
      The interrupt will be re-enabled properly later on, sometimes after
      mtk_eint_do_resume, when the driver is ready to handle it.
