David Hildenbrand 52767e1063 libvhost-user: Mark mmap'ed region memory as MADV_DONTDUMP ... We already use MADV_NORESERVE to deal with sparse memory regions. Let's also set madvise(MADV_DONTDUMP), otherwise a crash of the process can result in us allocating all memory in the mmap'ed region for dumping purposes. This change implies that the mmap'ed rings won't be included in a coredump. If ever required for debugging purposes, we could mark only the mapped rings MADV_DODUMP. Ignore errors during madvise() for now.
