      init: use do_mount() instead of ksys_mount() · cccaa5e3
      Dominik Brodowski authored
      In prepare_namespace(), do_mount() can be used instead of ksys_mount()
      as the first and third argument are const strings in the kernel, the
      second and fourth argument are passed through anyway, and the fifth
      argument is NULL.
      
      In do_mount_root(), ksys_mount() is called with the first and third
      argument being already kernelspace strings, which do not need to be
      copied over from userspace to kernelspace (again). The second and
      fourth arguments are passed through to do_mount() anyway. The fifth
      argument, while already residing in kernelspace, needs to be put into
      a page of its own. Then, do_mount() can be used instead of
      ksys_mount().
      
      Once this is done, there are no in-kernel users to ksys_mount() left,
      which can therefore be removed.

      Pull AFS fixes from David Howells:
       "Fixes for AFS plus one patch to make debugging easier:
      
         - Fix how addresses are matched to server records. This is currently
           incorrect which means cache invalidation callbacks from the server
           don't necessarily get delivered correctly. This causes stale data
           and metadata to be seen under some circumstances.
      
         - Make the dynamic root superblock R/W so that rpm/dnf can reapply
           the SELinux label to it when upgrading the Fedora filesystem-afs
           package. If the filesystem is R/O, this fails and the upgrade
           fails.
      
           It might be better in future to allow setxattr from an LSM to
           bypass the R/O protections, if only for pseudo-filesystems.
      
         - Fix the parsing of mountpoint strings. The mountpoint object has to
           have a terminal dot, whereas the source/device string passed to
           mount should not. This confuses type-forcing suffix detection
           leading to the wrong volume variant being mounted.
      
         - Make lookups in the dynamic root superblock for creation events
           (such as mkdir) fail with EOPNOTSUPP rather than something like
           EEXIST. The dynamic root only allows implicit creation by the
           ->lookup() method - and only if the target cell exists.
      
         - Fix the looking up of an AFS superblock to include the cell in the
           matching key - otherwise all volumes with the same ID number are
           treated as the same thing, irrespective of which cell they're in.
      
         - Show the volume name of each volume in the volume records displayed
           in /proc/net/afs/<cell>/volumes. This proved useful in debugging as
           it provides a way to map the volume IDs to names, where the names
           are what appear in /proc/mounts"

      pipe: simplify signal handling in pipe_read() and add comments · d1c6a2aa
      Linus Torvalds authored
      There's no need to separately check for signals while inside the locked
      region, since we're going to do "wait_event_interruptible()" right
      afterwards anyway, and the error handling is much simpler there.
      
      The check for whether we had already read anything was also redundant,
      since we no longer do the odd merging of reads when there are pending
      writers.
      
      But perhaps more importantly, this adds commentary about why we still
      need to wake up possible writers even though we didn't read any data,
      and why we can skip all the finishing touches now if we get a signal (or
      had a signal pending) while waiting for more data.
      
      [ This is a split-out cleanup from my "make pipe IO use exclusive wait
        queues" thing, which I can't apply because it triggers a nasty bug in
        the GNU make jobserver   - Linus ]

      afs: Fix missing cell comparison in afs_test_super() · 106bc798
      David Howells authored
      Fix missing cell comparison in afs_test_super().  Without this, any pair
      volumes that have the same volume ID will share a superblock, no matter the
      cell, unless they're in different network namespaces.
      
      Normally, most users will only deal with a single cell and so they won't
      see this.  Even if they do look into a second cell, they won't see a
      problem unless they happen to hit a volume with the same ID as one they've
      already got mounted.

      afs: Fix mountpoint parsing · 158d5833
      David Howells authored
      Each AFS mountpoint has strings that define the target to be mounted.  This
      is required to end in a dot that is supposed to be stripped off.  The
      string can include suffixes of ".readonly" or ".backup" - which are
      supposed to come before the terminal dot.  To add to the confusion, the "fs
      lsmount" afs utility does not show the terminal dot when displaying the
      string.
      
      The kernel mount source string parser, however, assumes that the terminal
      dot marks the suffix and that the suffix is always "" and is thus ignored.
      In most cases, there is no suffix and this is not a problem - but if there
      is a suffix, it is lost and this affects the ability to mount the correct
      volume.
      
      The command line mount command, on the other hand, is expected not to
      include a terminal dot - so the problem doesn't arise there.
      
      Fix this by making sure that the dot exists and then stripping it when
      passing the string to the mount configuration.

      afs: Fix afs_find_server lookups for ipv4 peers · 9bd0160d
      Marc Dionne authored
      afs_find_server tries to find a server that has an address that
      matches the transport address of an rxrpc peer.  The code assumes
      that the transport address is always ipv6, with ipv4 represented
      as ipv4 mapped addresses, but that's not the case.  If the transport
      family is AF_INET, srx->transport.sin6.sin6_addr.s6_addr32[] will
      be beyond the actual ipv4 address and will always be 0, and all
      ipv4 addresses will be seen as matching.
      
      As a result, the first ipv4 address seen on any server will be
      considered a match, and the server returned may be the wrong one.
      
      One of the consequences is that callbacks received over ipv4 will
      only be correctly applied for the server that happens to have the
      first ipv4 address on the fs_addresses4 list.  Callbacks over ipv4
      from all other servers are dropped, causing the client to serve stale
      data.
      
      This is fixed by looking at the transport family, and comparing ipv4
      addresses based on a sockaddr_in structure rather than a sockaddr_in6.

       "orangefs: posix open permission checking...
      
        Orangefs has no open, and orangefs checks file permissions on each
        file access. Posix requires that file permissions be checked on open
        and nowhere else. Orangefs-through-the-kernel needs to seem posix
        compliant.
      
        The VFS opens files, even if the filesystem provides no method. We can
        see if a file was successfully opened for read and or for write by
        looking at file->f_mode.
      
        When writes are flowing from the page cache, file is no longer
        available. We can trust the VFS to have checked file->f_mode before
        writing to the page cache.
      
        The mode of a file might change between when it is opened and IO
        commences, or it might be created with an arbitrary mode.
      
        We'll make sure we don't hit EACCES during the IO stage by using
        UID 0"
      
      [ This is "posixish", but not a great solution in the long run, since a
        proper secure network server shouldn't really trust the client like this.
        But proper and secure POSIX behavior requires an open method and a
        resulting cookie for IO of some kind, or similar.    - Linus ]

      We had cases in the previous patch where we were sending the security
      descriptor context on SMB3 open (file create) in cases when we hadn't
      mounted with with "modefromsid" mount option.
      
      Add check for that mount flag before calling ad_sd_context in
      open init.

      pipe: don't use 'pipe_wait() for basic pipe IO · 85190d15
      Linus Torvalds authored
      pipe_wait() may be simple, but since it relies on the pipe lock, it
      means that we have to do the wakeup while holding the lock.  That's
      unfortunate, because the very first thing the waked entity will want to
      do is to get the pipe lock for itself.
      
      So get rid of the pipe_wait() usage by simply releasing the pipe lock,
      doing the wakeup (if required) and then using wait_event_interruptible()
      to wait on the right condition instead.
      
      wait_event_interruptible() handles races on its own by comparing the
      wakeup condition before and after adding itself to the wait queue, so
      you can use an optimistic unlocked condition for it.
