* exportfs: taught exportfs -v about the nordirplus optionSteve Dickson2014-08-241-0/+2

* nfs-utils: Allow turning off nfsv3 readdir_plusRajesh Ghanekar2014-08-201-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | One of our customer's application only needs file names, not file attributes. With directories having 10K+ inodes (assuming buffer cache has directory blocks cached having file names, but inode cache is limited and hence need eviction of older cached inodes), older inodes are evicted periodically. So if they keep on doing readdir(2) from NSF client on multiple directories, some directory's files are periodically removed from inode cache and hence new readdir(2) on same directory requires disk access to bring back inodes again to inode cache. As READDIRPLUS request fetches attributes also, doing getattr on each file on server, it causes unnecessary disk accesses. If READDIRPLUS on NFS client is returned with -ENOTSUPP, NFS client uses READDIR request which just gets the names of the files in a directory, not attributes, hence avoiding disk accesses on server. There's already a corresponding client-side mount option, but an export option reduces the need for configuration across multiple clients. This flag affects NFSv3 only. If it turns out it's needed for NFSv4 as well then we may have to figure out how to extend the behavior to NFSv4, but it's not currently obvious how to do that.

* blkmapd: fix broken multipath handlingChristoph Hellwig2014-08-131-23/+4
| | | | | | | | | | | | | | | | | We do want to use the dm-multipath device if it exists, which the code is generally prepared for, except that this check excludes them early. In addition this will also add the passive path to the device list, which is harmless if an active one exists as that or the multipath device will be preferred, and at least allows us to work if it doesn't. Also fix up the check if an path needs to be updated to remove the silly partition check - pNFS block offset are relative to the device so partion should never match it instead of the full device. On the other hand the simplistic check easily creates false positives, e.g. dm-10 is considered a partition of dm-1.

* gssd: configurable connection timeout for the rpcgssd serviceRinku Kothiya2014-07-254-2/+19
| | | | | | | | | | | | | | | | | | | When using rpc.gssd to secure NFSv3 FS using krb5, the following errors can happen as a result of network congestion. "rpc.gssd WARNING: can't create tcp rpc_clnt to server ... : RPC: Remote system error - Connection timed out" we had a successful reproducer of the problem which we tested using this patch by starting rpc.gssd with "-T 60" as the option which solved the problem. reproducer steps were to throttle the network using tc command and then in a never ending loop mount the share, then write some data in the file on the share and unmount it. keep a delay of 5 sec between the iteration of each loop.

* mountd: add support for case-insensitive file namesSteve Dickson2014-06-171-2/+82
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Case insensitive filesystems support textually distinct names for the same directory. i.e. you can access it with a name other than the canonical name. For example if you mkdir /mnt/export then add /mnt/EXPORT to /etc/exports, and on a client mount server:/mnt/EXPORT /import then the mount will work, but if the kernel on the server needs to refresh the export information, it will ask about "/mnt/export", which is not listed in /etc/exports and so will fail. To fix this we need mountd to perform case-insensitive name comparisons, but only when the filesystem would, and in exactly the same way that the filesystem would. So, when comparing paths for equality first try some simple heuristics which will not be fooled by case and then ask the kernel if they are the same. By preference we use name_to_handle_at() as it reports the mntid which can distinguish between bind mounts. If that is not available, use lstat() and compare rdev and ino. Acked-by: J.

* [PATCH - v3] mount.nfs: Fix fallback from tcp to udpNeilBrown2014-03-133-18/+50
| | | | | | | | | | | | | | | | | | | | | | | | | Protocol negotiation in mount.nfs does not correctly negotiate with a server which only supports NFSv3 and UDP. When mount.nfs attempts an NFSv4 mount and fails with ECONNREFUSED it does not fall back to NFSv3, as this is not recognised as a "does not support NFSv4" error. However ECONNREFUSED is a clear indication that the server doesn't support TCP, and ipso facto does not support NFSv4. So ECONNREFUSED should trigger a fallback from v4 to v2/3. However ECONNREFUSED may simply indicate that NFSv4 isn't supported *yet*. i.e. the server is still booting and isn't responding to NFS requests yet. So if we subsequently find that NFSv3 is supported, we need to check with the server to confirm that NFSv4 really isn't supported. If server reports that v4 is not supported after reporting that v3 is, we can safely use v4. If it reports that v4 is supported, we need to retry v4.

* mountd: use SONAME fir libnfsjunct when loading with dlopenNeilBrown2014-03-111-2/+7
| | | | | | | | | | | | | | | | | | | | | | | The standard for loading shared libraries is to identify them by their "soname" (Which "objdump -x $BINARY | grep SONAME" will report). However mountd currently loads using the "linker name" which should only be used when building new code. Future releases of fedfs-utils will define the soname in the include file, so if that is defined, use it. If not, use the soname of the first version: "libnfsjunct.so.0". This is a slight behavioural change. However all distros known to package fedfs-utils will install "libnfsjunct.so.0" whenever they install the old name of "libnfsjunct.so", and "make install" will install both. So it should not be a noticeable change. Also only test the JP_API_VERSION if it is defined. As the version is embedded in the soname, a secondary test is not needed.
