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.

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

This solves kern/10312 by Martin J. Laubach.

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).

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.

40d9f8a709 msdosfs_read(): avoid integer overflow for files > 2GB, when
difference between current read position and file size
	is bigger than 2GB

This fixes problem first noted in FreeBSD PR#15639 and sent
by Martin J. Laubach in kern/9046, though the implementation
differs a bit.

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).
