junglefowl 373d9aff7a Fail if file is too large to mmap.

If tor_mmap_file is called with a file which is larger than SIZE_MAX,
only a small part of the file will be memory-mapped due to integer
truncation.

This can only realistically happen on 32 bit architectures with large
file support.

Raw Blame History

   o Minor bugfixes (portability):
     - Do not silently truncate content of files if they are larger
       than SIZE_MAX bytes. This issue could occur on 32 bit systems
       with large file support and files which are larger than 4 GB.
       Fixes bug 21134; bugfix on 0.3.0.1-alpha.
