glusterfs.git/xlators/nfs/server/src/mount3.h, branch v3.5.4beta1 gNFS: Fix multi-homed m/c issue in NFS subdir auth 2014-07-02T07:53:18+00:00 Niels de Vos ndevos@redhat.com 2014-06-29T14:30:30+00:00 cacc1311626aa8b2dfe9f937cf1b14bb534a8937 NFS subdir authentication doesn't correctly handle multi-homed (host with multiple NIC having multiple IP addr) OR multi-protocol (IPv4 and IPv6) network addresses. When user/admin sets HOSTNAME in gluster CLI for NFS subdir auth, mnt3_verify_auth() routine does not iterate over all the resolved n/w addrs returned by getaddrinfo() n/w API. Instead, it just tests with the one returned first. 1. Iterate over all the n/w addrs (linked list) returned by getaddrinfo(). 2. Move the n/w mask calculation part to mnt3_export_fill_hostspec() instead of doing it in mnt3_verify_auth() i.e. calculating for each mount request. It does not change for MOUNT req. 3. Integrate "subnet support code rpc-auth.addr.<volname>.allow" and "NFS subdir auth code" to remove code duplication.

NFS subdir authentication doesn't correctly handle multi-homed
(host with multiple NIC having multiple IP addr) OR multi-protocol
(IPv4 and IPv6) network addresses.

When user/admin sets HOSTNAME in gluster CLI for NFS subdir auth,
mnt3_verify_auth() routine does not iterate over all the resolved
n/w addrs returned by getaddrinfo() n/w API. Instead, it just tests
with the one returned first.

3. Integrate "subnet support code rpc-auth.addr.<volname>.allow"

nfs: persistent caching of connected NFS-clients 2013-08-28T13:54:44+00:00 Niels de Vos ndevos@redhat.com 2013-08-09T12:17:33+00:00 bbefeffafe9a2a5ba493e4bc0c9c9480d577e881 Introduce /var/lib/glusterfs/nfs/rmtab to contain a list of NFS-clients which have a volume mounted. The volume option 'nfs.mount-rmtab' can be set to an alternative filename. When the file is located on shared storage, multiple gNFS servers can use the same file to present a single NFS-server. This cache is read when a system administrator calls 'showmount -a' and updated when an NFS-client calls MNT or UMNT from the MOUNT protocol. Usage: - create a volume for storing the shared rmtab file - mount the volume on all storage servers, at the same location - make sure that the volume is mounted at boot (add to /etc/fstab) - place the rmtab file on the volume: # gluster volume set <VOLUME> nfs.mount-rmtab <MOUNTPOINT>/<FILENAME> - any subsequent mount requests will add an entry to this file - 'showmount -a' requests will return the NFS-clients using the cluster Note: The NFS-server does currently not support reconfigure(). When a configuration option is set/changed, the NFS-server glusterfs process gets restarted. This causes the active NFS-clients to be forgotten (the entries are saved in the old rmtab, but we do not have a reference to that file any more, so we can't re-add them). Therefor a re-mount done by the NFS-clients is needed before they get listed in the rmtab again.
