* Allow any credential to be used for machine credentialsKevin Coffman2007-03-192-18/+16
| | | | | | | | | | Don't restrict machine credentials to be "nfs/<machine.name>". Use any usable credentials contained in the keytab file. [We actually attempt to use the first entry found for each realm, not every entry, in the keytab.] Signed-off-by: Kevin Coffman <kwc@citi.umich.edu> Signed-off-by: Neil Brown <neilb@suse.de>
* Add option to allow root to use credentials other than machine credentialsKevin Coffman2007-03-194-54/+69
| | | | | | | | | | | | | | | | | | | | | | | | | | Add a new option ("-n") to rpc.gssd to indicate that accesses as root (uid 0) should not use machine credentials, but should instead use "normal" Kerberos credentials obtained by root. This change was prompted by a suggestion and patch from Daniel Muntz <Dan.Muntz@netapp.com>. That patch suggested trying "normal" credentials first and falling back to using machine creds for uid 0 if normal creds failed. This opens up the case where root may have credentials as "foo@REALM" and begins accessing files. Then the context using those credentials expires and must be renewed. If the credentials are now expired, then root's new context would fall back and be created with the machine credentials. Instead, this patch insists that the administrator choose to use either machine credentials for accesses by uid 0 (the default behavior, as it was before) or "normal" credentials. In the latter case, arrangements must be made to obtain credentials before attempting a mount. There should be no doubts which credentials are used for uid 0.

* Correctly handle "user" and "users" mount options.Neil Brown2007-03-163-6/+122
| | | | | | | | | | | | If "user" or "users" is given, then allow mount.nfs to be run by a non-root user providing that the mountpoint, filesystem, and options exactly match what is found in fstab. For "user", record the user name in mtab so they can unmount the filesystem later. Also alwasys ignore auto, owner, group and their negations as well as "_netdev", "comment" and "loop".

* On "umount --lazy", don't tell the server we have unmounted.Neil Brown2007-03-161-6/+7
| | | | | | Because, ofcourse, we haven't. When we do finally let-go of the mount, the server won't get told, but the same would happen on a crash, and the server just has to cope.
* Return correct exit status for umount.nfs.Neil Brown2007-03-161-1/+1

| | | | | | On distros that support 32 and 64bit userspace, we need to look a bit more broadly for libraries (taken from Redhat sources for RHEL5 - thanks).
* Allow 'make install' to be run as non-root.Neil Brown2007-03-161-1/+1
| | | | | Providing write access to the DESTDIR is ok, we shouldn't fail the install just because 'chown' fails.

* Further tidyup of nfs_umount.Neil Brown2007-03-161-65/+16
| | | | | | | | | | | | | | - remove non-used arguments from del_mtab. - Don't try to pass a "host:/path" string to umount. It used to be possible to umount("/dev/whatever"). It has never been possible to umount("host:/path"). - Don't try to read /proc/mounts first. Some mount options (mount_vers) are only stored in /etc/mtab, not in /proc/mounts. So we have to prefer /etc/mtab as getmntXbackwards do. - Only every call one of getmnt{dir,dev}backwards, depending on whether 'spec' looks like a path name or a host:/path. - Don't call _nfsumount unless we have a host:/path, or del_mtab unless we have a path name.

* Don't complain if two exports of different types match the same IP address.Neil Brown2007-03-161-2/+4
| | | | | | | As nfs-utils as an ordering of client types (hostname, netmask, wildcard, netgroup), it is expected that sometimes the one IP will match two or more of these and the first will over-ride. So don't both complaining when that happens.
* Install mount.nfs* in /sbin instead of /usr/sbinNeil Brown2007-03-161-3/+7
| | | | | | This patch is now hard-coded in the Makefile.am and cannot be changed by configure. But as it needs to match what util-linux does, that is probably a good thing.

* Automatically start statd when mounting an nfs filesystem.Neil Brown2007-03-164-7/+40
| | | | | | | | | | | If statd is not running (/var/run/rpc.statd.pid) when an nfs filesystem is mounted (v2 or v3, with remote locking enabled), and if /usr/sbin/start-statd (or other program specified at config time) is present, then run that program to start statd. This means that statd does not need to be running "just in case". It only needs to be started at boot time if the nfs server is started.
* Make --enable-secure-statd the default.Neil Brown2007-03-153-7/+39
| | | | | | | | | | | | | | i.e. you now need --disable-secure-statd if you want any client other than lockd to talk to statd. Also relax the RESTRICTED_STATD checks so that a recent kernel with /proc/sys/fs/nfs/nsm_use_hostnames set can still talk to statd. Finally, restrict access to simulate_crash so that only privileged processes on localhost can call it. Having it accessible by the whole world is probably not much more than a minor inconvenience, but it really should be kept closed.

* If -o sec= is not specified for mount, allow either AUTH_SYS or AUTH_NONE.Neil Brown2007-03-151-2/+10
| | | | | | | | | Solaris servers, when asked to share a filesystem with an anon-uid, will report the only available authentication style as AUTH_NONE in the reply from mountd (even though they actually accept AUTH_SYS and simply ignore the credentiuals). So if no sec= is specified we should really accept anything that can easily be handled. ie. AUTH_SYS or AUTH_NONE.

* Restore use of un-connected socket for UDP mount requests.Neil Brown2007-03-133-29/+37
| | | | | | | | | | | | | | | | | | | | | | When connecting to an NFSv4 server we need to find out IP address as it would be seen by the server, to register an address for callbacks. This is most easily done by connecting the socket to the servers address and then getting the address of our endpoint. However with a connected UDP socket, replies that come from a different IP address - as can happen with non-Linux multi-homed servers - will be rejected. So if we connected our UDP socket, we need to be sure to disconnect it before using it. This patch adds an option to get_socket to say if we want it connected or not and, in the case where we do, we disconnect a UDP socket after the connection information has been used. Also clean up the error handling in clnt_ping which was getting clumsy.
