      arm64: futex: Fix FUTEX_WAKE_OP atomic ops with non-zero result value · 045afc24
      Will Deacon 提交于
      Rather embarrassingly, our futex() FUTEX_WAKE_OP implementation doesn't
      explicitly set the return value on the non-faulting path and instead
      leaves it holding the result of the underlying atomic operation. This
      means that any FUTEX_WAKE_OP atomic operation which computes a non-zero
      value will be reported as having failed. Regrettably, I wrote the buggy
      code back in 2011 and it was upstreamed as part of the initial arm64
      support in 2012.
      
      The reasons we appear to get away with this are:
      
        1. FUTEX_WAKE_OP is rarely used and therefore doesn't appear to get
           exercised by futex() test applications
      
        2. If the result of the atomic operation is zero, the system call
           behaves correctly
      
        3. Prior to version 2.25, the only operation used by GLIBC set the
           futex to zero, and therefore worked as expected. From 2.25 onwards,
           FUTEX_WAKE_OP is not used by GLIBC at all.
      
      Fix the implementation by ensuring that the return value is either 0
      to indicate that the atomic operation completed successfully, or -EFAULT
      if we encountered a fault when accessing the user mapping.

      iommu/amd: Set exclusion range correctly · 3c677d20
      Joerg Roedel 提交于
      The exlcusion range limit register needs to contain the
      base-address of the last page that is part of the range, as
      bits 0-11 of this register are treated as 0xfff by the
      hardware for comparisons.
      
      So correctly set the exclusion range in the hardware to the
      last page which is _in_ the range.

      because it doesn't implement arch_irq_work_raise(), nor does it call
      irq_work_run() from it's PMU interrupt handler (nor would that be
      sufficient in this case, because s390 also generates
      perf_event_overflow() from pmu::stop). Add to that the fact that s390
      is a virtual architecture and (virtual) CPU-A can stall long enough
      for the above race to happen, even if it would self-IPI.
      
      Adding a irq_work_sync() to event_sched_in() would work for all hardare
      PMUs that properly use irq_work_run() but fails for software PMUs.
      
      Instead encode the CPU number in @pending_disable, such that we can
      tell which CPU requested the disable. This then allows us to detect
      the above scenario and even redirect the IPI to make up for the failed
      queue.

      NFSv4.1 fix incorrect return value in copy_file_range · 0769663b
      Olga Kornievskaia 提交于
      According to the NFSv4.2 spec if the input and output file is the
      same file, operation should fail with EINVAL. However, linux
      copy_file_range() system call has no such restrictions. Therefore,
      in such case let's return EOPNOTSUPP and allow VFS to fallback
      to doing do_splice_direct(). Also when copy_file_range is called
      on an NFSv4.0 or 4.1 mount (ie., a server that doesn't support
      COPY functionality), we also need to return EOPNOTSUPP and
      fallback to a regular copy.
      
      Fixes xfstest generic/075, generic/091, generic/112, generic/263

      NFS: Forbid setting AF_INET6 to "struct sockaddr_in"->sin_family. · 7c2bd9a3
      Tetsuo Handa 提交于
      syzbot is reporting uninitialized value at rpc_sockaddr2uaddr() [1]. This
      is because syzbot is setting AF_INET6 to "struct sockaddr_in"->sin_family
      (which is embedded into user-visible "struct nfs_mount_data" structure)
      despite nfs23_validate_mount_data() cannot pass sizeof(struct sockaddr_in6)
      bytes of AF_INET6 address to rpc_sockaddr2uaddr().
      
      Since "struct nfs_mount_data" structure is user-visible, we can't change
      "struct nfs_mount_data" to use "struct sockaddr_storage". Therefore,
      assuming that everybody is using AF_INET family when passing address via
      "struct nfs_mount_data"->addr, reject if its sin_family is not AF_INET.

      dma-debug: only skip one stackframe entry · 8c516543

      With skip set to 1, I get a traceback like this:

      With the previous value of 2, afu_dma_map_region was being omitted.  I
      suspect that the code paths have simply changed since the value of 2 was
      chosen a decade ago, but it's also possible that it varies based on which
      mapping function was used, compiler inlining choices, etc.  In any case,
      it's best to err on the side of skipping less.
