Hi Steve- This is server-side support for RPC-with-TLS, to accompany similar support in the Linux NFS client. This implementation can support both the opportunistic use of transport layer security (it will be used if the client cares to) and the required use of transport layer security (the server requires the client to use it to access a particular export). Without any other user space componentry, this implementation will be able to handle clients that request the use of RPC-with-TLS. To support security policies that restrict access to exports based on the client's use of TLS, modifications to exportfs and mountd are needed. These can be found here: git://git.linux-nfs.org/projects/cel/nfs-utils.git They include an update to exports(5) explaining how to use the new "xprtsec=" export option. The kernel patches, along with the the handshake upcall, are carried in the topic-rpc-with-tls-upcall branch available from: https://git.kernel.org/pub/scm/linux/kernel/git/cel/linux.git This was posted under separate cover. --- Chuck Lever (4): libexports: Fix whitespace damage in support/nfs/exports.c exports: Add an xprtsec= export option exportfs: Push xprtsec settings to the kernel exports.man: Add description of xprtsec= to exports(5) support/export/cache.c | 15 ++++++ support/include/nfs/export.h | 6 +++ support/include/nfslib.h | 14 +++++ support/nfs/exports.c | 100 ++++++++++++++++++++++++++++++++--- utils/exportfs/exportfs.c | 1 + utils/exportfs/exports.man | 45 +++++++++++++++- 6 files changed, 172 insertions(+), 9 deletions(-) -- Chuck Lever
