* Introduce '[ipaddr]:path' notation.ume2010-02-041-3/+10
| | | | | | | | | | | Since the existing implementation searches ':' backward, a path which includes ':' could not be mounted. You can now mount such path by enclosing an IP address by '[]'. Though we should change to search ':' forward, it will break 'ipv6addr:path' which is currently working. So, it still searches ':' backward, at least for now. MFC after: 2 weeks

* Take advantage of the use of file system IDs to simplify umount(8)iedowse2003-07-201-298/+144
| | | | | | | | | | | | | | | | | and make it work more reliably in a number of cases that have traditionally been troublesome. The new behaviour is: 1) If the filesystem can be determined by the fsid or device, or uniquely identified by the mountpoint, then just go ahead and call unmount(2) using the file system ID. 2) Otherwise use fstatfs(2) to resolve the path into a file system ID (checking with stat(2) that it is a filesystem root directory). Case 2 can potentially block if an NFS server is down, but it can always be avoided by using an unambiguous specification. It handles all the hard cases such as symlinks and mismatches between the mount list and reality. For example, if a filesystem was mounted as /mnt inside a chroot, it will show up in the mount list as /mnt, but now you can unmount it from outside the chroot with "umount /chroot_path/mnt".

| | | | | | | | | | | | ID for each file system in addition to the normal information. In umount(8), accept filesystem IDs as well as the usual device and path names. This makes it possible to unambiguously specify which file system is to be unmounted even when two or more file systems share the same device and mountpoint names (e.g. NFS mounts from the same export into different chroots).

Now that the file system to unmount is specified to the kernel using the filesystem ID, this confusion cannot occur, so remove the code that checked for it.

| | | | | | | | | | | | | | | | | | system by specifying the file system ID instead of a path. Use this by default in umount(8). This avoids the need to perform any vnode operations to look up the mount point, so it makes it possible to unmount a file system whose root vnode cannot be looked up (e.g. due to a dead NFS server, or a file system that has become detached from the hierarchy because an underlying file system was unmounted). It also provides an unambiguous way to specify which file system is to be unmunted. Since the ability to unmount using a path name is retained only for compatibility, that case now just uses a simple string comparison of the supplied path against f_mntonname of each mounted file system.

After these changes, it's possible to modify struct vfsconf without breaking the binary compatibility. Please note that these changes don't break this compatibility either. When bp will have updated mount_smbfs(8) with the patch I sent him, there will be no more consumers of the {set,get,end}vfsent(), vfsisloadable() and vfsload() API, and I will promptly delete it.

Add a missing return statement at the end of checkname(); this could result in a non-zero exit status in some cases even if the unmount succeeded. Group two separate NFS-related operations into one block to make it more obvious that a variable (hostp) is not dereferenced when uninitialised. Initialise it to NULL anyway to avoid a warning. Pass in the read_mtab()'s bogus argument as NULL instead of messing with a local variable to achieve the same effect. A later commit will clean up this mounttab interface.

Bring in required TLI library routines to support this. Since we don't support TLI we've essentially copied what NetBSD has done, adding a thin layer to emulate direct the TLI calls into BSD socket calls. This is mostly from Sun's tirpc release that was made in 1994, however some fixes were backported from the 1999 release (supposedly only made available after this porting effort was underway). The submitter has agreed to continue on and bring us up to the 1999 release. Several key features are introduced with this update: Client calls are thread safe. (1999 code has server side thread safe) Updated, a more modern interface. Many userland updates were done to bring the code up to par with the recent RPC API. There is an update to the pthreads library, a function pthread_main_np() was added to emulate a function of Sun's threads library. While we're at it, bring in NetBSD's lockd, it's been far too long of a wait. New rpcbind(8) replaces portmap(8) (supporting communication over an authenticated Unix-domain socket, and by default only allowing set and unset requests over that channel). It's much more secure than the old portmapper. Umount(8), mountd(8), mount_nfs(8), nfsd(8) have also been upgraded to support TI-RPC and to support IPV6. Umount(8) is also fixed to unmount pathnames longer than 80 chars, which are currently truncated by the Kernel statfs structure.
