Date: Wed, 17 Feb 2021 14:42:34 -0500 Message-Id: <20210217194240.79915-1-steved@redhat.com> MIME-Version: 1.0 X-Scanned-By: MIMEDefang 2.79 on 10.5.11.11 Precedence: bulk List-ID: X-Mailing-List: linux-nfs@vger.kernel.org exportd is a daemon that will listen for only v4 mount upcalls. The idea is to allow distros to build a v4 only package which will have a much smaller footprint than the entire nfs-utils package. exportd uses no RPC code, which means none of the code or arguments that deal with v3 was ported, this again, makes the footprint much smaller. The following options were ported: * multiple threads * state-directory-path option * junction support (not tested) The rest of the mountd options were v3 only options. V2: * Added two systemd services: nfsv4-exportd and nfsv4-server * nfsv4-server starts rpc.nfsd -N 3, so nfs.conf mod not needed. Steve Dickson (6): exportd: the initial shell of the v4 export support exportd: Moved cache upcalls routines into libexport.a exportd: multiple threads exportd/exportfs: Add the state-directory-path option exportd: Enabled junction support exportd: systemd unit files .gitignore | 1 + configure.ac | 1 + nfs.conf | 4 + support/export/Makefile.am | 3 +- {utils/mountd => support/export}/auth.c | 4 +- {utils/mountd => support/export}/cache.c | 46 +++- support/export/export.h | 34 +++ {utils/mountd => support/export}/fsloc.c | 0 {utils/mountd => support/export}/v4root.c | 0 {utils/mountd => support/include}/fsloc.h | 0 systemd/nfs.conf.man | 10 + systemd/nfsv4-exportd.service | 12 + systemd/nfsv4-server.service | 31 +++ utils/Makefile.am | 1 + utils/exportd/Makefile.am | 63 +++++ utils/exportd/exportd.c | 276 ++++++++++++++++++++++ utils/exportd/exportd.man | 81 +++++++ utils/exportfs/exportfs.c | 25 +- utils/exportfs/exportfs.man | 7 +- utils/mountd/Makefile.am | 5 +- 20 files changed, 586 insertions(+), 18 deletions(-) rename {utils/mountd => support/export}/auth.c (99%) rename {utils/mountd => support/export}/cache.c (98%) create mode 100644 support/export/export.h rename {utils/mountd => support/export}/fsloc.c (100%) rename {utils/mountd => support/export}/v4root.c (100%) rename {utils/mountd => support/include}/fsloc.h (100%) create mode 100644 systemd/nfsv4-exportd.service create mode 100644 systemd/nfsv4-server.service create mode 100644 utils/exportd/Makefile.am create mode 100644 utils/exportd/exportd.c create mode 100644 utils/exportd/exportd.man
