* Fix handling of explicit uuidDavid Woodhouse2008-08-281-1/+3
| | | | | | | | | | | Fix a couple of bugs which show up if you try to explicitly set a 16-byte UUID when exporting a file system. First, exportfs cuts the first two bytes off the UUID and writes something invalid to etab. Second, mountd writes the _ascii_ form of the UUID to the kernel, instead of converting it to hex.

* mount.nfs command: old glibc missing some flagsChuck Lever2008-07-311-0/+18
| | | | | | | | | | | | | | | | Old versions of glibc (< 2.4) have a getaddrinfo(3) implementation, but do not include public definitions of the AI_V4MAPPED, AI_ALL, and AI_ADDRCONFIG flags because it was believed that these flags were not standardized. However, these flags have standard definitions both in POSIX 1003 and in RFCs, and were thus included in later releases of glibc. To allow the mount.nfs command to build on systems with these older versions of glibc, add conditional definitions for these flags in utils/mount/network.c.

* sm-notify: perform DNS lookup in the background.Steve Dickson2008-07-251-20/+40
| | | | | | | | | | | | | If an NFS server has no network connectivity when it reboots, it will block in sm-notify waiting for DNS lookup for a potentially large number of hosts. This is not helpful and just annoys the sysadmin. So do the DNS lookup in the backgrounded phase of sm-notify, before sending off the NOTIFY requests.

* If portmap is not listening on UDP (as apparently happens withNeil Brown2008-07-161-4/+15
| | | | | | | | | | | | | | | | | | | MS-Windows-Server2003R2SP2), then nfs mounts have to be mounted with -o mountproto=tcp to succeed. In this case a umount will still try UDP and will fail to contact the server. It will still succeed with the local unmount (after a timeout) but exits with a non-zero exit status. This causes /bin/mount to retry so we get a strange error about the filesystem not being mounted. So: get umount to use tcp if "mountproto=tcp" appears in mtab ignore any failure message from the server that would overwrite a success message from the local umount syscall.

| | | | | | | | | | | | | | | MS-Windows-Server2003R2SP2 does), mount doesn't cope. There is retry logic in case the initial choice of version/etc doesn't work, but it doesn't cope with mountd needing tcp. So: Fix probe_port so that a TIMEDOUT error doesn't simply abort but probes with other protocols (e.g. tcp). Fix rewrite_mount_options to extract the mountproto option before doing a probe, then set mountproto (and mount prot) based on the result.

You can also substitute a specific IPv4 network address for the server hostname, like this: mount 192.168.0.55:/export /mounted/on/dir Raw IPv6 addresses present a problem, however, because they look something like this: fe80::200:5aff:fe00:30b Note the use of colons. To get around the presence of colons, copy the Solaris convention used for raw NFS server IPv6 addresses, which is to wrap the raw IPv6 address with square brackets. This is also suggested in RFC 4038. Introduce a new device name parser that can support traditional device names and square brackets. Place the parser in a separate source file so both the mount and umount paths can derive the server's hostname and export pathname the same way. Bonus points: add a check for NFS URLs and display an appropriate error message in that case. This is cleaner than failing with "unknown host: nfs".

* There were 2 things wrong with auth flavour ordering:bc Wong2008-03-182-6/+16
| | | | | | | | | | | | | | | | | | | | | | - Mountd used to advertise AUTH_NULL as the first flavour on the list, which means that it prefers AUTH_NULL to anything else (as per RFC 2623 section 2.7). - Mount.nfs used to scan the returned list in reverse order, and stopping at the first AUTH_NULL or AUTH_SYS encountered. If a server advertises (AUTH_SYS, AUTH_NULL), it will by default choose AUTH_NULL and have degraded access. I've fixed mount.nfs to scan from the beginning. For mountd, it does not advertise AUTH_NULL anymore. This is necessary to avoid backward compatibility issue. If AUTH_NULL appears in the list, either the new or the old client will choose that over AUTH_SYS. Tested the server/client combination against the previous versions, as well as Solaris and FreeBSD.
