Introduce write_threads, write_version and write_ports netlink commands similar to the ones available through the procfs. Changes since v5: - for write_ports and write_version commands, userspace is expected to provide a NFS listeners/supported versions list it want to enable (all the other ports/versions will be disabled). - fix comments - rebase on top of nfsd-next Changes since v4: - rebase on top of nfsd-next tree Changes since v3: - drop write_maxconn and write_maxblksize for the moment - add write_version and write_ports commands Changes since v2: - use u32 to store nthreads in nfsd_nl_threads_set_doit - rename server-attr in control-plane in nfsd.yaml specs Changes since v1: - remove write_v4_end_grace command - add write_maxblksize and write_maxconn netlink commands This patch can be tested with user-space tool reported below: https://github.com/LorenzoBianconi/nfsd-netlink.git Lorenzo Bianconi (3): NFSD: convert write_threads to netlink command NFSD: add write_version to netlink command NFSD: add write_ports to netlink command Documentation/netlink/specs/nfsd.yaml | 94 ++++++ fs/nfsd/netlink.c | 63 ++++ fs/nfsd/netlink.h | 10 + fs/nfsd/nfsctl.c | 396 ++++++++++++++++++++++ include/uapi/linux/nfsd_netlink.h | 44 +++ tools/net/ynl/generated/nfsd-user.c | 460 ++++++++++++++++++++++++++ tools/net/ynl/generated/nfsd-user.h | 155 +++++++++ 7 files changed, 1222 insertions(+) -- 2.43.0
