The intention of this page is to hold answers to frequently (and no so frequently) asked questions as well as some random data spread among developers' heads ;-)

  • Q: Why CRIU dumps parts of read-only mappings that map the code section of a binary? For instance, there is a mapping at, say 0x400000, that maps the code of /usr/bin/something. After dump there will be at least one page at 0x400000 or nearby in the pagemap
  • A: The code section may have been COWed, for instance during dynamic load of the shared libraries.
