      vfs: read file_handle only once in handle_to_path · 161f873b
      Sasha Levin authored
      We used to read file_handle twice.  Once to get the amount of extra
      bytes, and once to fetch the entire structure.
      
      This may be problematic since we do size verifications only after the
      first read, so if the number of extra bytes changes in userspace between
      the first and second calls, we'll have an incoherent view of
      file_handle.
      
      Instead, read the constant size once, and copy that over to the final
      structure without having to re-read it again.

      lib: Fix strnlen_user() to not touch memory after specified maximum · f18c34e4
      Jan Kara authored
      If the specified maximum length of the string is a multiple of unsigned
      long, we would load one long behind the specified maximum.  If that
      happens to be in a next page, we can hit a page fault although we were
      not expected to.
      
      Fix the off-by-one bug in the test whether we are at the end of the
      specified range.

      ia64: make cpu_callin_map non-volatile. · 5eda7861
      Rusty Russell authored
      cpumask_test_cpu() doesn't take volatile, unlike the obsoleted
      cpu_isset.  The only place ia64 really cares is the spin waiting for a
      bit; udelay() is probably a barrier but insert barrier() to be sure.

      dmaengine: hsu: Fix memory leak when stopping a running transfer · 42977082
      Peter Ujfalusi authored
      The vd->node is removed from the lists when the transfer started so the
      vchan_get_all_descriptors() will not find it. This results memory leak.

      x86/asm/irq: Stop relying on magic JMP behavior for early_idt_handlers · 425be567
      Andy Lutomirski authored
      The early_idt_handlers asm code generates an array of entry
      points spaced nine bytes apart.  It's not really clear from that
      code or from the places that reference it what's going on, and
      the code only works in the first place because GAS never
      generates two-byte JMP instructions when jumping to global
      labels.
      
      Clean up the code to generate the correct array stride (member size)
      explicitly. This should be considerably more robust against
      screw-ups, as GAS will warn if a .fill directive has a negative
      count.  Using '. =' to advance would have been even more robust
      (it would generate an actual error if it tried to move
      backwards), but it would pad with nulls, confusing anyone who
      tries to disassemble the code.  The new scheme should be much
      clearer to future readers.
      
      While we're at it, improve the comments and rename the array and
      common code.
      
      Binutils may start relaxing jumps to non-weak labels.  If so,
      this change will fix our build, and we may need to backport this
      change.
