      tag_chunk has bad exit paths in which the inotify ref counting is wrong.
      At the top of the function we found &old_watch using  inotify_find_watch().
      inotify_find_watch takes a reference to the watch.  This is never dropped
      on an error path.

      audit: Fix possible return value truncation in audit_get_context() · 6d208da8
      Paul Moore authored
      The audit subsystem treats syscall return codes as type long, unfortunately
      the audit_get_context() function mistakenly converts the return code to an
      int type in the parameters which could cause problems on systems where the
      sizeof(int) != sizeof(long).

      audit: ignore terminating NUL in AUDIT_USER_TTY messages · 55ad2f8d
      Miloslav Trmac authored
      AUDIT_USER_TTY, like all other messages sent from user-space, is sent
      NUL-terminated.  Unlike other user-space audit messages, which come only
      from trusted sources, AUDIT_USER_TTY messages are processed using
      audit_log_n_untrustedstring().
      
      This patch modifies AUDIT_USER_TTY handling to ignore the trailing NUL
      and use the "quoted_string" representation of the message if possible.

      Audit: fix handling of 'strings' with NULL characters · b3897f56
      Miloslav Trmac authored
      currently audit_log_n_untrustedstring() uses audit_string_contains_control()
      to check if the 'string' has any control characters.  If the 'string' has an
      embedded NULL audit_string_contains_control() will return that the data has
      no control characters and will then pass the string to audit_log_n_string
      with the total length, not the length up to the first NULL.
      audit_log_n_string() does a memcpy of the entire length and so the actual
      audit record emitted may then contain a NULL and then whatever random memory
      is after the NULL.
      
      Since we want to log the entire octet stream (if we can't trust the data
      to be a string we can't trust that a NULL isn't actually a part of it)
      we should just consider NULL as a control character.  If the caller is
      certain they want to stop at the first NULL they should be using
      audit_log_untrustedstring.

      audit: EXECVE record - removed bogus newline · ca96a895
      Jiri Pirko authored
      (updated)
      Added hunk that changes the comment, the rest is the same.
      
      EXECVE records contain a newline after every argument. auditd converts
      "\n" to " " so you cannot see newlines even in raw logs, but they're
      there nevertheless. If you're not using auditd, you need to work round
      them. These '\n' chars are can be easily replaced by spaces when
      creating record in kernel. Note there is no need for trailing '\n' in
      an audit record.
      
      record before this patch:
      "type=EXECVE msg=audit(1231421801.566:31): argc=4 a0=\"./test\"\na1=\"a\"\na2=\"b\"\na3=\"c\"\n"
      
      record after this patch:
      "type=EXECVE msg=audit(1231421801.566:31): argc=4 a0=\"./test\" a1=\"a\" a2=\"b\" a3=\"c\""

      ACPI: processor: use .notify method instead of installing handler directly · 7ec0a729
      Bjorn Helgaas authored
      This patch adds a .notify() method.  The presence of .notify() causes
      Linux/ACPI to manage event handlers and notify handlers on our behalf,
      so we don't have to install and remove them ourselves.

      Note that events from fixed hardware buttons now show up as a special
      notify event, so to preserve user-space backward compatibility, we
      convert that back to ACPI_BUTTON_NOTIFY_STATUS.

      ACPI: support acpi_device_ops .notify methods · 46ec8598
      Bjorn Helgaas authored
      This patch adds support for ACPI device driver .notify() methods.  If
      such a method is present, Linux/ACPI installs a handler for device
      notifications (but not for system notifications such as Bus Check,
      Device Check, etc).  When a device notification occurs, Linux/ACPI
      passes it on to the driver's .notify() method.
      
      In most cases, this removes the need for drivers to install their own
      handlers for device-specific notifications.
      
      For fixed hardware devices like some power and sleep buttons, there's
      no notification value because there's no control method to execute a
      Notify opcode.  When a fixed hardware device generates an event, we
      handle it the same as a regular device notification, except we send
      a ACPI_FIXED_HARDWARE_EVENT value.  This is outside the normal 0x0-0xff
      range used by Notify opcodes.
      
      Several drivers install their own handlers for system Bus Check and
      Device Check notifications so they can support hot-plug.  This patch
      doesn't affect that usage.
