The local version does some extra mangling of the mtab entries. We should check what util-linux does these days to be sure, but for now, let's make the mount.nfs command use the nfs_ variants of setmntent().

* When following a list of mount versions to probe -Steve Dickson2007-11-031-1/+1
| | | | | | | | | | | | | | | | | | | | e.g. probe_mnt1_first or probe_mnt3_first - probe_both will first probe the appropriate NFS version and then, if that succeeds, probe the actual mount version. However instead of probing the target mount version, it probes the "most appropriate" mount version for the given NFS version. This results in it probing: NFSv2, MOUNTv1 twice rather than NFSv2, MOUNTv1 NFSv2, MOUNTv2 as would be more correct. This patch removes the "choose most correct" step and just use the current mouint version for the probe_vers array.

* This means that if mountd is run with "--no-nfs-version 3",Steve Dickson2007-11-031-4/+0
| | | | | | | | | | | | | | | | It will first probe for NFS version 3, which will succeed (assuming the kernel supported NFSv3), then it will check the matching mountd version (3) and probe_port on discovering that isn't supported will try other versions, find "1" is supported will succeed. This leaves up using mount version 1 for an NFSv3 mount, which doesn't work and leads to a SIGSEGV There is no case where trying other versions is needed the request one is not supported, so simply remove that code.

* Cleanup xlog logging code to be safe and usable for allKevin Coffman2007-10-152-21/+48
| | | | | | | | | | | | | | | This patch reworks the xlog logging code to avoid rebuilding the message into a fixed size buffer. It also adds two new logging functions xlog_warn and xlog_err which are replacements for idmap_warn and idmap_err. There use to be two different variates of these functions with the only difference being that one flavor tacked on the error string to the end of the message. This responsibility has been pushed to the called of the function since it needlessly complicated the function and required us to rebuild the message strings. Signed-off-by: David P.

* text-based mount.nfs: Fix po_rightmost() enum return valuesChuck Lever2007-10-122-32/+25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Neil observed that po_rightmost() now returns enum values from both enum { PO_NOT_FOUND = 0, PO_FOUND = 1, } and enum { PO_KEY2_RIGHTMOST = 1, PO_KEY1_RIGHTMOST = -1, } It would be cleaner to use a single enum for po_rightmost()'s return value. We take the next logical step and create specific types for the return values in order to ensure we don't mix the enum values, and to document explicitly what return values callers can expect. This could have been a simpler patch, but I think the end result is a cleaner overall parser API. Signed-off-by: Chuck Lever <chuck.lever@oracle.com> Signed-off-by: Neil Brown <neilb@suse.de>

* Fix version fallback for unmount.Neil Brown2007-10-122-28/+16
| | | | | | | | | | | | | | | | Previously, if the mtab record didn't mention a version, unmount would assume a v3 umount and send an UNMOUNT request accordingly. This is wrong. So remove the 'v3' assumption, and allow probe_port to continue when it gets a version number mis-match. Also there was some overloading of the meaning of pm_vers==0 relating to v4 mounts. As do_nfs_umount is never called for v4, rename it to do_nfs_umount23, and remove v4 handling from there and from nfs_call_umount. Signed-off-by: Neil Brown <neilb@suse.de>
* Don't fail an unmount just because we couldn't contact the NFS server.Neil Brown2007-10-111-2/+1
| | | | | | | If we fail to talk to the NFS server when unmounted a v2 or v3 mount, still do the unmount, but allow the error to propagate up. Signed-off-by: Neil Brown <neilb@suse.de>

* text-based mount.nfs: Add functions to handle background mountingChuck Lever2007-10-111-0/+89
| | | | | | | | | | Add helper functions that handle background mounts; one each for foreground processing (to try the request, and determine when to fork); and one for background processing (retry the request multiple times as a forked background daemon).

* text-based mount.nfs: add function to do foreground retriesChuck Lever2007-10-111-0/+51
| | | | | | | | | | | | Make the differences between the foreground and background mount logic explicit by creating separate functions to handle each -- think of them as separate scripts for doing a foreground or a background mount. NFS foreground mounts are supposed to retry for a little while before giving up. Add a function to handle this.

* text-based mount.nfs: sort between permanent and temporary errorsChuck Lever2007-10-111-0/+21
| | | | | | | | | | | | | The text-based mount.nfs program must distinguish between different types of errors returned from the kernel. Permanent errors, like bad mount options, should cause an immediate failure. Temporary errors, such as a connection timeout, should result in a retry of some type. Add a function that sorts between the two types of errors. The list of permanent errors can be adjusted later if needed.

* text-based mount.nfs: Implement falling back to NFSv2 and UDPChuck Lever2007-10-111-2/+64
| | | | | | | | | | | | | | | | | If the initial user-specified options fail (with EOPNOTSUPP or EPROTONOSUPPORT) then the server has rejected the requested NFS version or transport protocol. In that case, probe the server, then construct a fresh set of mount options that ask for the specific mountd and NFS version and transport protocol that the server supports. Rewrite the mount options based on the results of the probe, then try the request again. An additional kernel patch is required to cause the kernel to return EOPNOTSUPP when an rpcbind fails during a NULL request.

* text-based mount.nfs: Add rewrite_mount_options() functionChuck Lever2007-10-111-0/+130

* text-based mount.nfs: Create helpers for invoking mount(2) system callChuck Lever2007-10-091-0/+74
| | | | | | | | | | Add simple helper functions that invoke the mount(2) system call for text-based mounts. These look the same right now, but the NFSv2/v3 helper will become more complex over the following patches as we implement version and transport protocol fallback.

| | | | | | | | | The top-level logic that handles text-based mount options is mostly the same for NFS and NFSv4 mounts.

* text-based mount.nfs: Fix mounthost= processingChuck Lever2007-09-291-0/+27
| | | | | | | | | | | | | | | | | | | | | The 'mounthost=' option names a host where the mountd service is running. The option is used to direct clients to use a different host for the mountd procotol than the host where the NFS service is running. The nfs(5) man page shows that the 'mounthost=' option takes a name, not an address. The kernel's text-based mount option parsing logic expects an IPv4 address. This is necessary because the kernel cannot itself resolve hostnames to addresses. Resolve the hostname and pass in a new mount option that contains the resolved address, 'mountaddr=', to the kernel. This requires a patch to the kernel to recognize the new 'mountaddr=' option, and to change the 'mounthost=' parsing logic to treat the value of this option as a simple string.

* text-based mount.nfs: Use new parser to handle 'addr=' and 'clientaddr='Chuck Lever2007-09-291-0/+55
| | | | | | | | | | | Introduce, but don't yet use, functions that will eventually replace append_addr_opt() and append_clientaddr_opt().

* text-based mount.nfs: parse option strings into listsChuck Lever2007-09-293-2/+478
| | | | | | | | | | | | | | | | | | | | | Adapt a parsing trick used by Python. Parse mount option strings into an abstract data type so we don't have to copy and/or tokenize the whole option string multiple times while trying to manipulate the mount options. Then, just before calling the mount(2) system call, convert the object back into a C string. One major advantage of this approach is that we can copy the final version of the mount options into /etc/mtab when we're done, instead of copying in the original mount options that the user specified. Any fallback from NFS v3 to NFS v2 or TCP to UDP that was done by mount.nfs will be reflected in /etc/mtab. This patch adds methods for creating and manipulating mount option data objects.

* mount.nfs: add new string tokenizer facilityChuck Lever2007-09-293-2/+188
| | | | | | | | | | | | | | | | To quote the strtok(3) man page: "Avoid using these functions." OK. We've created our own. The main reason for this is that strtok(3) doesn't handle quoted delimiters at all. We need to handle this: context="foo,bar" where 'context' is a single mount option that sets a token string that possibly uses the same delimiter that the mount command uses to separate options (that is, a comma).
