maya be48413a3c Be explicit about how we're placing part of the on-disk name into 
the extension, so it doesn't appear like we are overrunning an array.
Appeases coverity, NFC.

hannken 70ec436e39 Move vnode members "v_freelisthd" and "v_freelist" from "struct vnode" 
to "struct vnode_impl" and rename to "vi_lrulisthd" and "vi_lrulist".

dholland 398f572480 Apparently a recent round of vandalism by the C++ standards committee 
includes disallowing the standard and historic type name "unsigned". Add
a gratuitous "int" to recent changes.

dholland 05d075b3ae Add VOP_FALLOCATE and VOP_FDISCARD to every vnode ops table I can 
find.

The filesystem ones all call genfs_eopnotsupp - right now I am only
implementing the plumbing and we can implement fallocate and/or
fdiscard for files later.

The device ones call spec_fallocate (which is also genfs_eopnotsupp)
and spec_fdiscard, which dispatches to the device-level op.

The fifo ones all call vn_fifo_bypass, which also ends up being
EOPNOTSUPP.

maxv 549e231932 Make DPRINTF more understandable, and replace my previous #ifdef DIAGNOSTIC... 2014-07-18 17:24:34 +00:00
maxv 8ee3c88d2b Limit the minimum size of a disk sector to 512 bytes, to prevent memory 
overflow on extremely low secsize. This normally conforms to the old standard
(for which there doesn't seem to be a clear spec). Since 2011, IDEMA's Advanced
Format standardizes it to 4k, so this change won't cause any trouble on
new devices.

Put the printf under DIAGNOSTIC temporarily to see if someone complains.

maxv 1273c3cb8c - Perform sanity checks not just for GEMDOSFS, but for all FAT devices. This 
also fixes a division-by-zero bug that could crash the system.
- Define GEMDOSFS_BSIZE instead of a hard-coded 512 value, and remove 'bsize'.
- Rename 'tmp' to 'BlkPerSec'.

From me, FreeBSD, OpenBSD and the FAT specification.

hannken 798256c9ef Change msdosfs from hashlist to vcache: 
- Use (dir_cluster, dir_offset, dir_generation) as key, where
  dir_generation is non-zero and unique for unlinked but open nodes.
- Change deget() to return a vnode as it is unsafe to return a
  referenced but unlocked denode.

christos 02cb0c6eaf Introduce a selector function to the vfs vnode iterator so that we don't 
need to vget() vnodes that we are not interested at, and optimize locking
a bit. Iterator changes reviewed by Hannken (thanks), the rest of the bugs
are mine.

maxv 23f76b6d00 An (un)privileged user can easily make the kernel dereference a NULL 
pointer.

The kernel allows 'data' to be NULL; it's the fs's responsibility to
ensure that it isn't NULL (if the fs actually needs data).

jakllsch e7f2d5bd6f Don't attempt to mount file system with clusters larger than MAXBSIZE. 2013-04-15 14:10:59 +00:00
plunky 5ec364d4d9 C99 section 6.7.2.3 (Tags) Note 3 states that: 
A type specifier of the form

	enum identifier

  without an enumerator list shall only appear after the type it
  specifies is complete.

which means that we cannot pass an "enum vtype" argument to
kauth_access_action() without fully specifying the type first.
Unfortunately there is a complicated include file loop which
makes that difficult, so convert this minimal function into a
macro (and capitalize it).
