      proc: Use new_inode not new_inode_pseudo · ef1548ad
      Eric W. Biederman authored
      Recently syzbot reported that unmounting proc when there is an ongoing
      inotify watch on the root directory of proc could result in a use
      after free when the watch is removed after the unmount of proc
      when the watcher exits.
      
      Commit 69879c01 ("proc: Remove the now unnecessary internal mount
      of proc") made it easier to unmount proc and allowed syzbot to see the
      problem, but looking at the code it has been around for a long time.
      
      Looking at the code the fsnotify watch should have been removed by
      fsnotify_sb_delete in generic_shutdown_super.  Unfortunately the inode
      was allocated with new_inode_pseudo instead of new_inode so the inode
      was not on the sb->s_inodes list.  Which prevented
      fsnotify_unmount_inodes from finding the inode and removing the watch
      as well as made it so the "VFS: Busy inodes after unmount" warning
      could not find the inodes to warn about them.
      
      Make all of the inodes in proc visible to generic_shutdown_super,
      and fsnotify_sb_delete by using new_inode instead of new_inode_pseudo.
      The only functional difference is that new_inode places the inodes
      on the sb->s_inodes list.
      
      I wrote a small test program and I can verify that without changes it
      can trigger this issue, and by replacing new_inode_pseudo with
      new_inode the issues goes away.

      Pull the Kernel Concurrency Sanitizer from Thomas Gleixner:
       "The Kernel Concurrency Sanitizer (KCSAN) is a dynamic race detector,
        which relies on compile-time instrumentation, and uses a
        watchpoint-based sampling approach to detect races.
      
        The feature was under development for quite some time and has already
        found legitimate bugs.
      
        Unfortunately it comes with a limitation, which was only understood
        late in the development cycle:
      
           It requires an up to date CLANG-11 compiler
      
        CLANG-11 is not yet released (scheduled for June), but it's the only
        compiler today which handles the kernel requirements and especially
        the annotations of functions to exclude them from KCSAN
        instrumentation correctly.
      
        These annotations really need to work so that low level entry code and
        especially int3 text poke handling can be completely isolated.
      
        A detailed discussion of the requirements and compiler issues can be
        found here:
      
          https://lore.kernel.org/lkml/CANpmjNMTsY_8241bS7=XAfqvZHFLrVEkv_uM4aDUWE_kh3Rvbw@mail.gmail.com/
      
        We came to the conclusion that trying to work around compiler
        limitations and bugs again would end up in a major trainwreck, so
        requiring a working compiler seemed to be the best choice.
      
        For Continous Integration purposes the compiler restriction is
        manageable and that's where most xxSAN reports come from.
      
        For a change this limitation might make GCC people actually look at
        their bugs. Some issues with CSAN in GCC are 7 years old and one has
        been 'fixed' 3 years ago with a half baken solution which 'solved' the
        reported issue but not the underlying problem.
      
        The KCSAN developers also ponder to use a GCC plugin to become
        independent, but that's not something which will show up in a few
        days.
      
        Blocking KCSAN until wide spread compiler support is available is not
        a really good alternative because the continuous growth of lockless
        optimizations in the kernel demands proper tooling support"

      Pull atomics rework from Thomas Gleixner:
       "Peter Zijlstras rework of atomics and fallbacks. This solves two
        problems:
      
         1) Compilers uninline small atomic_* static inline functions which
            can expose them to instrumentation.
      
         2) The instrumentation of atomic primitives was done at the
            architecture level while composites or fallbacks were provided at
            the generic level. As a result there are no uninstrumented
            variants of the fallbacks.
      
        Both issues were in the way of fully isolating fragile entry code
        pathes and especially the text poke int3 handler which is prone to an
        endless recursion problem when anything in that code path is about to
        be instrumented. This was always a problem, but got elevated due to
        the new batch mode updates of tracing.
      
        The solution is to mark the functions __always_inline and to flip the
        fallback and instrumentation so the non-instrumented variants are at
        the architecture level and the instrumentation is done in generic
        code.
      
        The latter introduces another fallback variant which will go away once
        all architectures have been moved over to arch_atomic_*"

      lib/lzo: fix ambiguous encoding bug in lzo-rle · b5265c81
      Dave Rodgman authored
      In some rare cases, for input data over 32 KB, lzo-rle could encode two
      different inputs to the same compressed representation, so that
      decompression is then ambiguous (i.e.  data may be corrupted - although
      zram is not affected because it operates over 4 KB pages).
      
      This modifies the compressor without changing the decompressor or the
      bitstream format, such that:
      
       - there is no change to how data produced by the old compressor is
         decompressed
      
       - an old decompressor will correctly decode data from the updated
         compressor
      
       - performance and compression ratio are not affected
      
       - we avoid introducing a new bitstream format
      
      In testing over 12.8M real-world files totalling 903 GB, three files
      were affected by this bug.  I also constructed 37M semi-random 64 KB
      files totalling 2.27 TB, and saw no affected files.  Finally I tested
      over files constructed to contain each of the ~1024 possible bad input
      sequences; for all of these cases, updated lzo-rle worked correctly.
      
      There is no significant impact to performance or compression ratio.

      ocfs2: fix build failure when TCP/IP is disabled · fce1affe
      Tom Seewald authored
      After commit 12abc5ee ("tcp: add tcp_sock_set_nodelay") and commit
      c488aead ("tcp: add tcp_sock_set_user_timeout"), building the kernel
      with OCFS2_FS=y but without INET=y causes it to fail with:
      
        ld: fs/ocfs2/cluster/tcp.o: in function `o2net_accept_many':
        tcp.c:(.text+0x21b1): undefined reference to `tcp_sock_set_nodelay'
        ld: tcp.c:(.text+0x21c1): undefined reference to `tcp_sock_set_user_timeout'
        ld: fs/ocfs2/cluster/tcp.o: in function `o2net_start_connect':

        ld: tcp.c:(.text+0x2643): undefined reference to `tcp_sock_set_user_timeout'
      
      This is due to tcp_sock_set_nodelay() and tcp_sock_set_user_timeout()
      being declared in linux/tcp.h and defined in net/ipv4/tcp.c, which
      depend on TCP/IP being enabled.
      
      To fix this, make OCFS2_FS depend on INET=y which already requires
      NET=y.

      mm/memory-failure: send SIGBUS(BUS_MCEERR_AR) only to current thread · 03151c6e
      Naoya Horiguchi authored
      Action Required memory error should happen only when a processor is
      about to access to a corrupted memory, so it's synchronous and only
      affects current process/thread.
      
      Recently commit 872e9a20 ("mm, memory_failure: don't send
      BUS_MCEERR_AO for action required error") fixed the issue that Action
      Required memory could unnecessarily send SIGBUS to the processes which
      share the error memory.  But we still have another issue that we could
      send SIGBUS to a wrong thread.
      
      This is because collect_procs() and task_early_kill() fails to add the
      current process to "to-kill" list.  So this patch is suggesting to fix
      it.  With this fix, SIGBUS(BUS_MCEERR_AR) is never sent to non-current
      process/thread.

      mm/memory-failure: prioritize prctl(PR_MCE_KILL) over vm.memory_failure_early_kill · 4e018b45
      Naoya Horiguchi authored
      Patch series "hwpoison: fixes signaling on memory error"
      
      This is a small patchset to solve issues in memory error handler to send
      SIGBUS to proper process/thread as expected in configuration.  Please
      see descriptions in individual patches for more details.
      
      This patch (of 2):
      
      Early-kill policy is controlled from two types of settings, one is
      per-process setting prctl(PR_MCE_KILL) and the other is system-wide
      setting vm.memory_failure_early_kill.  Users expect per-process setting
      to override system-wide setting as many other settings do, but
      early-kill setting doesn't work as such.
      
      For example, if a system configures vm.memory_failure_early_kill to 1
      (enabled), a process receives SIGBUS even if it's configured to
      explicitly disable PF_MCE_KILL by prctl().  That's not desirable for
      applications with their own policies.
      
      This patch is suggesting to change the priority of these two types of
      settings, by checking sysctl_memory_failure_early_kill only when a given
      process has the default kill policy.
      
      Note that this patch is solving a thread choice issue too.
      
      Originally, collect_procs() always chooses the main thread when
      vm.memory_failure_early_kill is 1, even if the process has a dedicated
      thread for memory error handling.  SIGBUS should be sent to the
      dedicated thread if early-kill is enabled via
      vm.memory_failure_early_kill as we are doing for PR_MCE_KILL_EARLY
      processes.

      dt-bindings: Fix more incorrect 'reg' property sizes in examples · 0db958b6
      Rob Herring authored
      The examples template is a 'simple-bus' with a size of 1 cell for
      had between 2 and 4 cells which really only errors on I2C or SPI type
      devices with a single cell.
      
      The easiest fix in most cases is to change the 'reg' property to 1 cell
      for address and size.

      The patch introducing the struct was probably never compile tested,
      because it sets a handler with a wrong function signature. Wrap the
      handler into a functions with the correct signature to fix the build.

      dt-bindings: phy: qcom: Fix missing 'ranges' and example addresses · c0eca14c
      Rob Herring authored
      The QCom QMP PHY bindings have child nodes with translatable (MMIO)
      addresses, so a 'ranges' property is required in the parent node.
      Additionally, the examples default to 1 address and size cell, so let's
      fix that, too.

      dt-bindings: Remove more cases of 'allOf' containing a '$ref' · 086e9074
      Rob Herring authored
      Another round of 'allOf' removals that came in this cycle.
      
      json-schema versions draft7 and earlier have a weird behavior in that
      any keywords combined with a '$ref' are ignored (silently). The correct
      form was to put a '$ref' under an 'allOf'. This behavior is now changed
      in the 2019-09 json-schema spec and '$ref' can be mixed with other
      keywords. The json-schema library doesn't yet support this, but the
      tooling now does a fixup for this and either way works.
      
      This has been a constant source of review comments, so let's change this
      treewide so everyone copies the simpler syntax.
