The AF_VSOCK address family allows virtual machines to communicate with the hypervisor using a zero-configuration transport. Both KVM and VMware hypervisors support AF_VSOCK and it was introduced in Linux 3.9. This patch series adds AF_VSOCK support to mount.nfs(8) and rpc.nfsd(8). It requires the kernel NFS client patches that I am also posting to linux-nfs@xxxxxxxxxxxxxxx. Please see the kernel patch series for an overview of NFS over AF_VSOCK and quickstart instructions for testing. This series extends exports(5) syntax to handle vsock:<CID> or vsock:*. For example, the guest with CID 3 can be given access using vsock:3. The code is also available here: https://github.com/stefanha/nfs-utils/tree/vsock-nfsd Stefan Hajnoczi (12): mount: don't use IPPROTO_UDP for address resolution nfs-utils: add AF_VSOCK support to sockaddr.h mount: present AF_VSOCK addresses mount: accept AF_VSOCK in nfs_verify_family() getport: recognize "vsock" netid mount: AF_VSOCK address parsing exportfs: introduce host_freeaddrinfo() exportfs: add AF_VSOCK address parsing and printing exportfs: add AF_VSOCK support to set_addrlist() exportfs: add support for "vsock:" exports(5) syntax nfsd: add --vsock (-v) option to nfsd tests: add "vsock:" exports(5) test case tests/Makefile.am | 3 +- support/include/exportfs.h | 6 ++ support/include/sockaddr.h | 29 +++++++ utils/nfsd/nfssvc.h | 1 + support/export/client.c | 8 +- support/export/hostname.c | 183 +++++++++++++++++++++++++++++++++++++++++++-- support/nfs/getport.c | 16 +++- utils/exportfs/exportfs.c | 42 +++++++++-- utils/mount/network.c | 10 ++- utils/mount/stropts.c | 67 +++++++++++++++-- utils/mountd/auth.c | 2 +- utils/mountd/cache.c | 10 +-- utils/mountd/mountd.c | 4 +- utils/mountd/rmtab.c | 2 +- utils/nfsd/nfsd.c | 18 ++++- utils/nfsd/nfssvc.c | 62 +++++++++++++++ tests/t0002-vsock-basic.sh | 53 +++++++++++++ 17 files changed, 474 insertions(+), 42 deletions(-) create mode 100755 tests/t0002-vsock-basic.sh -- 2.9.4 -- To unsubscribe from this list: send the line "unsubscribe linux-nfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
