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.

fvdl e1829fbf01 Fix error in previous change: don't use the local FS mount data before
it's actually allocated. Pass mount arguments to msdosfs_mountfs instead,
and use them (as in iso_mountfs for example).
1996-01-21 16:35:29 +00:00
leo 85ea3b1702 Instead of using '#ifdef atari' to handle the differences of Gemdosfs and
Msdosfs, use a flag that can be set by mount_msdos. This is definitely
more flexible.

1995-09-09 19:38:00 +00:00
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.
1995-07-24 21:19:27 +00:00
leo 891ce379fd Make the msdosfs driver understand Atari-gemdos filesystems. Although they
have much in common, there are some differences in the bpb/bootsector that
needed to be handled in the mounting code. The gemdos bpb/bootsector structs
are included for clarification.

cgd 8f62c773e8 don't assume the f_fsnamelen is nul-truncated or longer than MFSNAMELEN 1995-06-18 14:45:14 +00:00
mycroft 6b8a5d7b8e Update a comment in deupdat() to reflect current reality. 1995-06-02 16:19:55 +00:00
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 320cd8e632 Fix typo. 1995-06-02 14:54:53 +00:00
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.
