      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\""
