* lookup_export: really prefer nonV4ROOT exports.NeilBrown2012-05-011-3/+7
| | | | | | | | | | | | lookup_export() claims to "Always prefer non-V4ROOT mounts" (meaning "exports") but actually prefers V4ROOT exports - once it has 'found' one it will never replace it. So fix that inversion, and add code so that it proactively prefers a non-V4ROOT whether it is found before or after a V4ROOT.

* mountd: support IPv6 [] escaping with fsloc hostsWeston Andros Adamson2012-05-011-3/+17
| | | | | | | | | | | | | mountd uses colons to split fsloc hosts, but this doesn't work with IPv6 addresses (they contain ':'). To fix this, mountd is changed to expect all IPv6 addresses to be escaped by '[' and ']' so colons that are part of the address may be skipped. To fix IPv6 referrals, this patch must be used with the nfsd patch that properly parses escaped IPv6 addresses in fs_location->hosts.

* osd_login: Add autologin script for objlayoutdriverSachin Bhamare2012-05-011-0/+1
| | | | | | | | | | | | | | | | From: Sachin Bhamare <sbhamare@panasas.com> This script is part of the autologin feature mandated by the pnfs-objects standard. It is called from objlayoutdriver.ko in the kernel. It invokes iscsiadm program to perform the iscsi login to OSDs. It also features a watchdog which will make sure that control returns to kernel after 15s timeout.

* nfsdcld: add routines for a sqlite backend databaseJeff Layton2012-04-264-8/+298
| | | | | | | | | | | | | | | | | | | | Rather than roll our own "storage engine", use sqlite instead. It fits the bill nicely as it does: - durable on-disk storage - the ability to constrain record uniqueness - a facility for collating and searching the host records ...it does add a build dependency to nfs-utils, but almost all modern distros provide those packages. The current incarnation of this code dynamically links against a provided sqlite library, but we could also consider including their single-file "amalgamation" to reduce dependencies (though with all the caveats that that entails).

* autoconf: only link binaries that need it to libtirpcJeff Layton2012-01-166-8/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch is essentially the same as the previous version, but has been respun to fix up some merge conflicts with some of Chuck's recent changes. When we first added tirpc support, we took a "big hammer" approach, and had it add libtirpc to $LIBS. That had the effect of making it so that that library was linked into every binary. That's unnecessary, and wasteful with memory. Don't let AC_CHECK_LIB add -ltirpc to $LIBS. Instead, have the autoconf tests set $(LIBTIRPC) in the makefiles, and have the programs that need it explicitly include that library. In the event that we're not using libtirpc, then set $LIBTIRPC to a blank string. This necessitates a change to the bindresvport_sa check too. Since that library is no longer included in $LIBS, we need to convert that check to use AC_CHECK_LIB instead of AC_CHECK_FUNCS. This patch also fixes a subtle bug. If the library was usable, but the includes were not, the test would set $enable_tirpc to "no", but HAVE_LIBTIRPC would still be true. That configuration would likely fail to build.

* mountd: Support junction management plug-insChuck Lever2012-01-052-2/+225
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | To support FedFS and NFS junctions without introducing additional build-time or run-time dependencies on nfs-utils, the community has chosen to use a dynamically loadable library to handle junction resolution. There is one plug-in library for mountd that will handle any NFS- related junction type. Currently there are two types: o nfs-basic locally stored file set location data, and o nfs-fedfs file set location data stored on an LDAP server mountd's support for this library is enabled at build time by the presence of the junction API definition header: /usr/include/nfs-plugin.h If this header is not found on the build system, mountd will build without junction support, and will operate as before. Note that mountd does not cache junction resolution results. NFSD already caches these results in its exports cache. Thus each time NFSD calls up to mountd, it is, in essence, requesting a fresh junction resolution operation, not a cached response.

* sm-notify: sm-notify leaves monitor records in sm.bakChuck Lever2011-09-201-13/+22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | sm-notify fails to remove monitor records from sm.bak when it has finally notified a host. This is because of a recent change to send two SM_NOTIFY requests for each monitored peer: one with the local host's FQDN, and one with an unqualified version of same. This was commit baa41b2c: "sm-notify: Send fully-qualified and unqualified mon_names" (March 19, 2010). Because of the March 2010 commit, sm-notify modifies the "my_name" string during notification, but then uses this modified string to try to find the monitor record to remove. Of course the search for the record fails. So a persistent monitor record is left in sm.bak. Aside from leaving trash around, this causes the same hosts to be notified after every reboot, even if they successfully responded to the previous SM_NOTIFY and they had no contact with us during the last boot. I also noticed that the trick of truncating the argument of SM_NOTIFY doesn't work at all if a substitute "my_name" was specified via the "-v" command line option. This patch attempts to address that as well. sm-notify should preserve the original my_name string so that nsm_delete_host() can find the correct monitor record to delete. Also add some degree of protection to the mon_name and my_name strings in each nsm_host record to prevent a future change from breaking this dependency.

* sm-notify: Avoid extra rpcbind queriesChuck Lever2011-09-201-0/+1
| | | | | | | | | | | | | | | | The logic in notify_host() watches the host->retries counter to see if progress is not being made. If progress stalls, notify_host() tries another IP address. This means sm-notify will generate a fresh rpcbind query. After an RPC succeeds, be sure to reset host->retries so sm-notify doesn't start walking down the host's addrinfo list when we _are_ making progress. In the common case, if the host responds, we avoid extra rpcbind queries and send all requests for the host to the same IP address.
