fvdl b27bafebd5 We're only handling uio with iovcnt == 1, so don't ever attempt to increment
uio_iov, this will get us into nasty trouble. (Thanks to Matthias Drochner for
tracking this down).

pk 6e8ba625ef Ignore the mountpoint's `v_usecount' in nfs_unmount() if MNT_FORCE is on.
This takes care of two related problems:
	- `umount -f' wouldn't work if someone's working directory is
	  the filesystem root.
	- vfs_unmountall() would complain about a busy `/' on a
	  diskless setup.

cgd d73abf41aa avoid unnecessary checks of m_get/MGET/etc.'s return values. When
they're called with M_WAIT, they are defined to never return NULL.
1996-06-14 22:21:12 +00:00
cgd d9d0cc229c fix two bugs (the latter potentially fatal) in xdr_string_encode():
(1) if length needed was > MCLBYTES, an mbuf would be lost, and
(2) the wrong check was being used to determine if MCLGET succeeded.

fvdl 2847784948 * Make mounts with symlinks work (needed for direct mounts with amd). PR #1917
* Never change the NQNFS flag and/or version when just doing an update mount.
  Fixes a problem that made diskless booting impossible under some
  circumstances.

mycroft 49d52c9b1c Pass a proc pointer down to the usrreq and pcbbind functions for PRU_ATTACH, PRU_BIND and
PRU_CONTROL.  The usrreq interface really needs to be split up, but this will have to wait.

mycroft 261382c331 Change VOP_UPDATE() semantics:

* Consistently pass a Boolean as the 4th arg (except in LFS).
Also, fix ffs_update() and lfs_update() to actually change the nsec fields.

thorpej 3b8a528094 Changed struct ifnet to have a pointer to the softc of the underlying
device and a printable "external name" (name + unit number), thus eliminating
if_name and if_unit.  Updated interface to (*if_watchdog)() and (*if_reset)()
to take a struct ifnet *, rather than a unit number.

fvdl f5e6df1ed0 Disable invalidating of directory offsets cookies. Should fix one or two
directory problems.

XXX There is no clean solution to the cookie/cookieverifier validity mess.
    Together with the disabled strict cookie check, this puts us back at
    what v2 did in this case. Slightly better solution possible by
    consequently storing 64bit cookies in other places too.

mycroft c9c8301a91 Fix vop_link, vop_symlink, and vop_remove semantics in several ways:
* Change the argument names to vop_link so they actually make sense.
* Implement vop_link and vop_symlink for all file systems, so they do proper
  cleanup.
* Require the file system to decide whether or not linking and unlinking of
  directories is allowed, and disable it for all current file systems.
(Also, remove the cross-device link check, that was moved into the file
systems some time ago.)

ghudson d61f235615 Add cookie support. Stash cookies in the word prior to the end of
each entry, and read them out in nfs_readdir().

Caveat: our current caching method for directory blocks uses the
server offset of the first directory entry as an identifier, so a
Linux emulation getdirentries() will wind up retrieving one block from
the NFS server for each directory entry, unnecessarily thrashing the
cache.  The situation isn't as bad for other emulations.

Instead of getblk(), we need to write a routine to scan each cache
block associated with vp to find a cookie that matches at some
directory entry.  Some later time.
