jdolecek 057458abac msdosfs_getattr(): do not report archived files (those with ATTR_ARCHIVE unset)
as having flag SF_ARCHIVED on; this is wrong for directories, which don't
have any mode flags on msdosfs, so it's always treated as archived,
which leads to problems described in pr #8439. The semantics of the
archive flag differs between Unix and msdos/windoze, so it's better
to not set the flag at all even for regular files, to avoid surprises.

This fixes bin/8439 by Thomas Klausner.

jdolecek 61253f1dc8 msdosfs_rename(): fix too many vrele()'s of fdvp in some error cases;
bug and fix found on OpenBSD, though the fix is implemented very
differently here - we avoid changing correct code and only touch
what needs touching

jdolecek b0fb24279c change the lf_advlock() arguments from
int     lf_advlock __P((struct lockf **,
           off_t, caddr_t, int, struct flock *, int));
to

int     lf_advlock __P((struct vop_advlock_args *, struct lockf **, off_t));

This matches common usage and is also compatible with similar change
in FreeBSD (though they use u_quad_t as last arg).

mycroft 4656dfd24f Add a new function to remove extra buffers when truncating a file. This is
more generic than the vinvalbuf(V_SAVEMETA) case, avoiding synchronous
operations when truncating to a non-zero length.

perseant f0728fdce1 Change the sementics of the last parameter from a boolean ("waitfor") to
a set of flags ("flags").  Two flags are defined, UPDATE_WAIT and
UPDATE_DIROP.

Under the old semantics, VOP_UPDATE would block if waitfor were set,
under the assumption that directory operations should be done
synchronously.  At least LFS and FFS+softdep do not make this
assumption; FFS+softdep got around the problem by enclosing all relevant
calls to VOP_UPDATE in a "if(!DOINGSOFTDEP(vp))", while LFS simply
ignored waitfor, one of the reasons why NFS-serving an LFS filesystem
did not work properly.

Under the new semantics, the UPDATE_DIROP flag is a hint to the
fs-specific update routine that the call comes from a dirop routine, and
should be wait for, or not, accordingly.

Closes PR#8996.

jdolecek 07fd899a7f Add new CLUST_END and use it as parameter to pcbmap() when searching
for end cluster, instead of explicitly passing 0xffff. This fixes potential
problem for FAT32, where cluster number may be legally bigger than 0xffff.

Also change clusteralloc() so that fillwith is not explicitly passed by caller
anymore (there is no need to use anything other than CLUST_EOFE).

jdolecek e2698cd72a Fix definition of MSDOSFSEOF(), which got broken in rev. 1.13.
It's shape is a bit different now than it was in rev 1.12, but is functionally
equivalent. Also add a comment explaining it's sense.

This fixes breakage reported after LP64 fixes in kern/8037, and
also kern/9116 and kern/9206.

jdolecek 89015c4648 Add new VFS op routine - vfs_done and call it on filesystem detach
in vfs_detach(). vfs_done may free global filesystem's resources,
typically those allocated in respective filesystem's init function.
Needed so those filesystems which went in via LKM have a chance to
clean after themselves before unloading. This fixes random panics
when LKM for filesystem using pools was loaded and unloaded several
times.

For each leaf filesystem, add appropriate vfs_done routine.

jdolecek f759642ae2 Fix a problem in previous: we can't blindly assume that we have
wincnt entries available at the offset the file has been found. If the dos
directory entry is not preceded by appropriate number of long name
entries (happens e.g. when the filesystem is corrupted, or when
the filename complies to DOS rules and doesn't use any long name entry),
we would overwrite random directory entries.

There are still some problems, the whole thing has to be revisited and solved
right.

jdolecek ead528ba12 msdosfs_lookup(): initialize denode's de_fndcnt properly even for
"found" case. This information is important for msdosfs_rename(),
when the target filename is "long" and the file exists -
it gets unlinked and the entries are re-used, but if de_fndcnt was
left zero, createde() thinks there are no entries to store the
long filename of moved file and long filename is "lost".
