mycroft 53fccab940 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.

ws 29fff9256a Don't forward credentials to bread, it makes nfs panic

Handle root directories that are not multiple clusters in size

cgd e9d17d38b5 avoid unnecessary aging of buffers. This used to make sense, when buffer
caches were much smaller, but makes little sense now, and will become more
useless as RAM (and buffer cache) sizes grow.  Suggested by Bob Baron.

mycroft 7aeec96289 Various changes:
* Update the `archive' bit any time the file's time stamp is updated.
* Don't set the `archive' bit automatically for directories, and don't
update the time stamp of directories automatically.  (There are the DOS
semantics.)
* Use DE_TIMES() to change the time stamp in deupdat().  Remove the extra
time stamp argument, as it's superfluous, and we may want to make changes
without touching the time stamp.
* Allow denode updates iff DE_MODIFIED is set after DE_TIMES() is called.
This allows us to make changes that are totally independent of the time
stamp, and to avoid rewriting the entry if the time stamp was ignored (e.g.
for directories).
* Make time stamp changes in setattr() asynchronous.

mycroft dc4b7aaed2 Set the `archive' bit on created files. Copy some code from UFS to do better
permission checking in setattr().
1995-06-02 14:52:34 +00:00
mycroft 641dc38337 Require the denode to be locked before calling msdosfs_hashins(), rather than
inlining the rest of the code in reinsert().  (No functional changes.)  Also,
make sure that we don't print the (bogus) lock values when !DIAGNOSTIC.
Partly based on a patch from Mike Pritchard.

cgd 54eb3b1f88 brought in fixed/renamed/matching MS-DOS FS code, from Jeff Polk
<polk@bsdi.com>.  His notes are as follows:
------------------------------------------------------------------------------

 July 22, 1993

 - Changed name of entire package from PCFS to MSDOSFS

 - Fixed bugs:
      root directory size in clusters instead of bytes
      growing directory didn't update in-core size
      link, symlink, mknod didn't free locked parent (deadlock)
      lookup returned real error on create and rename instead of EJUSTRETURN
      rename changed `.' entry in child instead of name entry in parent
      rename removed `.' entry in child instead of removing entry in
              parent when moving a directory from one dir to another
      createde() left new node locked when write of parent failed (deadlock)
      removede() decremented refcount even on error (rmdir's which failed
              due to write errors left in-core cache entries inconsistent)
      changed validation for filesystem to not check for the boot signature
              since some disks (e.g., mtools) aren't bootable
      directories are always show current time as modify time
              (needed for NFS export since DOS never updates dir mod times --
               ctime is true create time).

 - Added support for cookies changes to the readdir() vnode
      interface (#ifdef __bsdi__)

 - Punted on the whole problem of inode generation numbers.  This means
   that there's a chance of using a stale file handle to access a new
   file, but it doesn't appear to be the common case, and I don't see
   how to generate reasonable generation numbers without changing something
   on the disk (which is the way the SVR4 filesystem survival kit guys
   did it).  I don't think it would be very safe to change the on-disk
   format.

        Jeff Polk (polk@BSDI.COM)
