mycroft 2bc736661a Implement poll(2). 1996-09-07 12:40:22 +00:00
mycroft c52352c819 Add a set of generic file system operations that most file systems use.
Also, fix some time stamp bogosities.

ws debbf2f60e - Add support for Win'95 separate creation/modification/access timestamps
- Re-introduce lowercase filenames for non-Win'95-filesystems

ws 29fff9256a Don't forward credentials to bread, it makes nfs panic
(Of course, nfs shouldn't rely on the credentials not being referenced)
Don't give directory entry to deget, it could result in a deadlock
Use device blocks, not clusters for logical block numbers

ws 6820273c34 Don't allow setattr on msdos directories (fixes pr kern/1436)
Correct handling of rmdir'ing open directories
Correct implementation of rename (includes renaming of directories)
Handle root directories that are not multiple clusters in size

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 b67fe41d0a Nuke second arg to DE_TIMES(). 1995-01-04 06:03:11 +00:00
mycroft 7225b8231e Push more of the time conversion code into unix2dostime(). Maintain the
ATTR_ARCHIVE bit according to DOS semantics, and allow it to be changed by chflags(2).

mycroft 527b796ff5 Turn lease_check() into a vnode op, per CSRG. 1994-12-13 20:14:30 +00:00
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.
