Since we have separate handler on POLLHUP, which drops data after closing the connection we need to fix this test, because it sends data and instantly close the socket creating race condition. In some cases on other end of socket client closes it faster than reads data. To prevent it I suggest to close socket after recieving.

This will exercise the memfd memory backend and should generally be better for testing than memory-backend-file (thanks to anonymous files and sealing). If memfd is available, it is preferred. However, in order to check that file & memfd backends both work correctly, the read-guest-mem test is checked explicitly for each.

Add a new memory backend, similar to hostmem-file, except that it doesn't need to create files. It also enforces memory sealing. This backend is mainly useful for sharing the memory with other processes. Note that Linux supports transparent huge-pages of shmem/memfd memory since 4.8. It is relatively easier to set up THP than a dedicate hugepage mount point by using "madvise" in /sys/kernel/mm/transparent_hugepage/shmem_enabled. Since 4.14, memfd allows to set hugetlb requirement explicitly. Pending for merge in 4.16 is memfd sealing support for hugetlb backed memory.

Linux commit 749df87bd7bee5a79cef073f5d032ddb2b211de8 (v4.14-rc1) added a new flag MFD_HUGETLB to memfd_create() that specify the file to be created resides in the hugetlbfs filesystem. This is the generic hugetlbfs filesystem not associated with any specific mount point. hugetlbfs does not support sealing operations in v4.14, therefore specifying MFD_ALLOW_SEALING with MFD_HUGETLB will result in EINVAL. However, I added sealing support in "[PATCH v3 0/9] memfd: add sealing to hugetlb-backed memory" series, queued in -mm tree for v4.16.
