mycroft e3f99a9397 Pass the vnode type to vaccess(), and use it when checking VEXEC. Make sure
that the mode bits passed to vaccess() and returned by foo_getattr() contain
only permission bits.

cgd ce53653783 make the namei struct members ni_dirp and ni_next, and the componentname
struct member cn_nameptr 'const', since they should never be used to
modify the path name.  (Only the pathname buffer, cn_pnbuf, should be
modified.)  Propagate the const poisoning to code that uses the namei
and componentname structs.

mycroft ae583dca34 Various changes:
* Make some of the code look more like UFS.
* Check permissions in lookup().
* Move the directory size special case into DE_EXTERNALIZE().
* Fix some conditions where lookup() might not release a buffer.
* Remove bogus flag handling in setattr().
* Pass timespec, not timeval, to deupdat().
* Check more error conditions.
* Fix possible panics in rename().
* Simplify readdir().
* General code cleanup; add prototypes, delete unused variables, etc.

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)
