* gNFS: mnt3_find_export() by pass AUTH checkSantosh Kumar Pradhan2014-01-081-14/+36
| | | | | | | | | | | | | | | | | | | | NFS subdir mount does not respect nfs.rpc-auth-reject option in the volume. If the volume is being mounted, then it would validate the AUTH by mnt3_check_client_net() but if the client is mounting a subdir, the control takes a different code path i.e. mnt3_find_export() which does not bother about the AUTH. FIX: Enforce the AUTH check in mnt3_parse_dir_exports() which is invoked by mnt3_find_export() for subdir mount.

* NFS: showmount timesout on fetching export listRajesh Joseph2013-10-041-8/+21
| | | | | | | | | | | | | | | | | | | | | | Bug: 1015184 Issue: showmount timesout on fetching export list. Socket writev function is failing. Cause: XDR encoding of export list is failing. The calling function without checking the error returned by xdr_serialize_exports function is going ahead and writting into the socket causing the NFS process to hang. xdr_serialize_exports function returns -1 on error and message length on success. Fix: Caller should check if the function is returning -1 (error) or not before proceeding.

* nfs: persistent caching of connected NFS-clientsNiels de Vos2013-08-281-56/+380
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | Problem: NFS allows exporting subdirectories but there is not support for providing AUTH on per directory basis. Fix: Modified nfs.export-dir to include AUTH parameters e.g. nfs.export-dir "/dir1(10.1.1.2),/dir2(10.1.1.0/24|host1) During mount operation NFS will check if the IP from where the connection is made is configured in the AUTH parameter, else the mount operation will fail with EACCES error.

* nfs, nfs3: Base volume access on CHILD-UP-DOWN eventShehjar Tikoo2010-09-221-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Overall, the aim of this patch is to change the result of an nfs op depending on whether the underlying volume is up or down as notified by CHILD_UP and CHILD_DOWN events. This patch contains three intertwined changes: o Only when the lookup on the root of a volume is successful does gnfs now export the subvolume. Till now the result of the lookup was not used to determine whether we should export that volume. Not accounting for root lookup failure resulted in ESTALEs on first access because some children of distribute were down at the time of the root lookup. o Only when lookups on all the subvolumes have succeeded are these exports enabled through NFS. o When a child of say distribute goes down, on CHILD_DOWN event nfs will ignore all incoming requests from the client because ignoring these will prevent ESTALEs for those requests and in the hope that ignoring the requests will make the client retransmit. There are risks in this approach absent the DRC but we're willing to live with that for now. When a child goes down, the mount exports list will continue to show it but mount requests will be denied.

* nfs: Support directory level exportsShehjar Tikoo2010-07-041-45/+649
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | nfsx has followed traditional approach of exporting whole volumes as NFS exports. The Platform requires and some users have approached us for introducing exports of only specific directories instead of full Gluster volumes. This commit introduces this support through two nfsx options: Option 1: ========= option nfs3.<volume-name>.export-dir <subdir1-in-vol>,<subdir2-in-vol>,..<subdirN-in-vol> export-dir will allow the export of a particular dir as a single export by itself. For eg.: volume posix type storage/posix option directory /export/ end-volume volume posix-ac type features/access-control subvolumes posix end-volume volume nfs type nfs/server subvolumes posix-ac option rpc-auth.addr.allow * option nfs3.posix-ac.export-dir /homes/shehjart end-volume A comma separate list of sub-directories will set up those dirs as separated exports. At the nfs client, the mount command will be: $ mount <nfsserver>:/posix-ac/homes/shehjart /mnt Option 2: ========= option nfs3.<volume-name>.export-volumes <on|off> There can be situations where users only want the directory level exports and require that volume exports be completely disabled. The above option allows us to do this. By default, volume exports are enabled. From the earlier example, replacing <volume-name> with posix-ac, will disable mounting of the posix-ac volume as a whole. Signed-off-by: Shehjar Tikoo <shehjart@gluster.com> Signed-off-by: Anand V.
