Removed the 'doc' directory from ntfsprogs.
It contains interesting information but this information is available elsewhere and we want to stay as close to ntfs-3g as possible. No unnecessary added files.

The standard K&R coding style is used in this project and the guidelines
|
||||
outlined in the Linux kernel CodingStyle document (found in the latest Linux
|
||||
kernel main directory in Documentation/CodingStyle) should be adhered to as
|
||||
strictly as possible.
|
||||
|
||||
Special notes:
|
||||
|
||||
Capitals are used when declaring NTFS on-disk structures which you
|
||||
can't just go ahead modifying without getting killed (in a bug sense,
|
||||
not literally...). In memory structures are named with lower case as
|
||||
usual.
|
||||
|
||||
For styles that are not explicitly defined in the document or in the
|
||||
kernel one, check/read the kernel and/or libntfs source. Some parts
|
||||
of the kernel might use unwanted coding styles but usually, e.g.
|
||||
linux/kernel/*
|
||||
has what Linus prefers/writes and most developers follow.
|
||||
|
||||
The latest Linux kernel contains the script Lindent in the scripts/
|
||||
directory which formats the source the most preferred way. Moreover,
|
||||
the below patch will be applied to the official kernel tree as well:
|
||||
http://lkml.org/lkml/2004/1/30/180
|
||||
Check indent(1) for what the used/unused (default) parameters mean.

Notes on the storage of attributes.
|
||||
===================================
|
||||
|
||||
Resident attributes
|
||||
===================
|
||||
|
||||
Resident attributes are small enough to be stored in the mft record itself.
|
||||
|
||||
When an attribute becomes too big to fit in the mft record or when the number
|
||||
of attributes grows so large that there is no more space in the mft record, the
|
||||
largest attribute(s) is(are) made non-resident. (Note, that some attributes
|
||||
cannot be non-resident.)
|
||||
|
||||
Non-resident attributes
|
||||
=======================
|
||||
|
||||
Non-resident attributes contain only their non-resident attribute header in the
|
||||
mft record and the actual attribute value is stored anywhere on the volume
|
||||
(but not in other mft records).
|
||||
|
||||
The value of the attribute is saved as a sequence of clusters, named virtual
|
||||
clusters, beginning at virtual cluster number (vcn) zero. Each vcn corresponds
|
||||
to a cluster on the volume, or a logical cluster number (lcn). The lcns on the
|
||||
volume begin with lcn zero for the very first cluster on the volume.
|
||||
|
||||
The location of the attribute value is described by the mapping pairs array
|
||||
present in the non-resident attribute header structure. The mapping pairs array
|
||||
contains, in compressed form, the mapping between the attribute's vcns and the
|
||||
corresponding lcns on the volume.
|
||||
|
||||
When the mapping pairs array of a non-resident attribute becomes too large to
|
||||
fit in the mft record or when there are so many attributes in the mft record
|
||||
that, even though all attributes that can be non-resident have been made
|
||||
non-resident, they still do not fit in the mft record, the larger non-resident
|
||||
attributes are moved away from the mft record to make space.
|
||||
|
||||
This is done by moving whole non-resident attribute header structures to other
|
||||
mft records and/or by splitting the mapping pairs array of attributes into
|
||||
several non-resident attribute headers, each containing a chunk of the
|
||||
original mapping pairs array. These non-resident attribute headers each
|
||||
describing the same attribute value (but different parts of it) are called
|
||||
extents.
|
||||
|
||||
Attribute list attribute
|
||||
========================
|
||||
|
||||
The attribute list attribute is then added to the base mft record to describe
|
||||
the location of each attribute.
|
||||
|
||||
The attribute list attribute lists all attributes that belong to this mft
|
||||
record (with the exception of itself). Each entry in the attribute list
|
||||
describes the attribute listed and in which mft record its attribute header can
|
||||
be found. For resident attributes this will be the same number as the base mft
|
||||
record in which the attribute list attribute is located itself. For non-resident
|
||||
attributes, this will be another mft record, called an extension mft record.
|
||||
Naturally, all extension mft records point back to their base mft record.
|
||||
|
||||
Only one attribute is stored in an extension mft record, even if the attribute
|
||||
is very small. At least this is the case with Windows NT4 SP6a driver.
|
||||
|
||||
Should the mapping pairs array of an attribute become so large as to not fit
|
||||
into an extenstion mft record, even though its attribute is the only attribute
|
||||
in this extension record, then the attribute is splitt into several extents.
|
||||
The first extent starts at vcn 0 and has its lowest vcn value set to zero and
|
||||
continues up to its highest vcn value. This is determined by splitting up the
|
||||
mapping pairs array into chunks which just fit into an extension mft record
|
||||
each. Thus the first mapping pairs array chunk will determine the value of
|
||||
the highest vcn for the first extent. The attribute list will contain an entry
|
||||
for this extent. Then, a second extent is created which has its lowest vcn
|
||||
value set to the highest vcn of the previous extent + 1 and the next chunk of
|
||||
the mapping pairs array is inserted into this extent. Again, an entry for this
|
||||
extent is placed into the attribute list, and so on, until the whole
|
||||
non-resident attribute's mapping pairs array has been accomodated.
|
||||
|
||||
Should the attribute list become too big to fit inside the base mft record it
|
||||
is made non-resident. However, it's maximum value size is determined by the
|
||||
Windows cache manager to be 256kb (the size of a VACB). Also, the mapping pairs
|
||||
array of the attribute list has to fit inside the base mft record, as an
|
||||
attribute list can't be described by itself and attribute lists are not allowed to be nested.
|
||||
|
||||
Compressed attributes
|
||||
=====================
|
||||
|
||||
The attribute value of each $DATA attribute can be compressed to save space.
|
||||
If this is the case, the ATTR_IS_COMPRESSED flag is set.
|
||||
|
||||
See the discussion on compression in include/attrib.h for more details.
|
||||
FIXME: The discussion belongs here! (AIA)
|
||||
|
||||
Sparse attributes (NTFS 3.0+)
|
||||
=============================
|
||||
|
||||
The attribute value of each $DATA attribute can be sparse to save space.
|
||||
If this is the case, the ATTR_IS_SPARSE flag is set. Note, that compressed
|
||||
attributes are by definition sparse, as well as compressed, without having the
|
||||
ATTR_IS_SPARSE flag set.
|
||||
|
||||
See the discussion on compression in include/attrib.h for more details.
|
||||
FIXME: The discussion belongs here! (AIA)
|
||||
|
||||
Encrypted attributes (NTFS 3.0+)
|
||||
================================
|
||||
|
||||
Since NTFS 3.0, the attribute value of each $DATA attribute can be encrypted,
|
||||
to protect the contents from spying eyes. If this is the case, the
|
||||
ATTR_IS_ENCRYPTED flag is set.
|
||||
|
||||
FIXME: Write notes on attribute encryption. The discussions from the articles
|
||||
"Inside the Encrypting File System" in Windows NT magazine (?) are very good
|
||||
starting points. (AIA)

Description of the NTFS (de)compression algorithm (based on a modified LZ77
|
||||
algorithm)
|

|
||||
Copyright (c) 2001 Anton Altaparmakov
|
||||
|
||||
This document is published under the GNU General Public License.
|
||||
|
||||
Credits: This is based on notes taken from various places (most notably from
|
||||
Regis Duchesne's NTFS documentation and from various LZ77 descriptions) and
|
||||
further refined by looking at a few compressed streams to figure out some
|
||||
uncertainties.
|
||||
|
||||
Note: You should also read the runlist description with regards to compression
|
||||
in linux-ntfs/include/layout.h. Just search for "Attribute compression".
|
||||
FIXME: Should merge the info from there into this document some time.
|
||||
|
||||
Compressed data is organized in logical "compression" blocks (cb). Each cb has
|
||||
a size (cb_size) of 2^compression_unit clusters. In all versions of Windows,
|
||||
NTFS (NT/2k/XP, NTFS 1.2-3.1), the only valid compression_unit is 4, IOW, each
|
||||
cb is 2^4 = 16 clusters in size.
|
||||
|
||||
We detect and warn about a compression_unit != 4 but we try to decompress the
|
||||
data anyway.
|
||||
|
||||
Compression is only supported for cluster sizes between 512 and 4096. Thus a
|
||||
cb can be between 8 and 64kiB in size.
|
||||
|
||||
Each cb is independent of the other cbs and is thus the minimal unit we have
|
||||
to parse even if we wanted to decompress only one byte.
|
||||
|
||||
Also, a cb can be totally uncompressed and this would be indicated as a sparse
|
||||
cb in the runlist.
|
||||
|
||||
Thus, we need to look at the runlist of the compressed data stream, starting
|
||||
at the beginning of the first cb overlapping @page. So we convert the page
|
||||
offset into units of clusters (vcn), and round the vcn down to a mutliple of
|
||||
cb_size clusters.
|
||||
|
||||
We then scan the runlist for the appropriate position. Based on what we find
|
||||
there, we decide how to proceed.
|
||||
|
||||
If the cb is not compressed at all, and covers the whole of @page, we pretend
|
||||
to be accessing an uncompressed file, so we fall back to what we do in
|
||||
aops.c::ntfs_file_readpage(), i.e. we do:
|
||||
return block_read_full_page(page, ntfs_file_get_block);
|
||||
|
||||
If the cb is completely sparse, and covers the whole of @page, we can just
|
||||
zero out @page and complete the io (set @page up-to-date, unlock it, and
|
||||
finally return 0).
|
||||
|
||||
In all other cases we initiate the decompression engine, but first some more
|
||||
on the compression algorithm.
|
||||
|
||||
Before compression the data of each cb is further divided into 4kiB blocks, we
|
||||
call them "sub compression" blocks (sb), each including a header specifying
|
||||
its compressed length. So we could just scan the cb for the first sb
|
||||
overlapping @page and skip the sbs before that, or we could decompress the
|
||||
whole cb injecting the superfluous decompressed pages into the page cache as a
|
||||
form of read ahead (this is what zisofs does for example).
|
||||
|
||||
In either case, we then need to read and decompress all sbs overlapping @page,
|
||||
potentially having to decompress one or more other cbs, too.
|
||||
|
||||
As soon as @page is completed we could either stop or continue until we finish
|
||||
the current cb, injecting pages as we go along (again following the zisofs
|
||||
example).
|
||||
|
||||
Because the sbs follow each other directly, we need to actually read in the
|
||||
whole cb in order to be able to scan through the cb to find the first sb
|
||||
overlapping @page, so it does make sense to follow the zisofs approach of
|
||||
decompressing the whole cb and injecting pages as we go along. So all
|
||||
discussion from now on will assume that we are going to do that. Although it
|
||||
might make sense not to decompress any sbs locate before @page because this
|
||||
would be a kind of "read-behind" which is probably silly, unless someone is
|
||||
reading the file backwards. Performing read-ahead by decompressing all sbs
|
||||
following @page OTOH, is very likely to be a good idea.
|
||||
|
||||
So, we read the whole cb from disk and start at the first sb.
|
||||
|
||||
As mentioned above, each sb is started with a header. The header is 16 bits of
|
||||
which the lower twelve bits (i.e. bits 0 to 11) are the length (L) - 3 of the
|
||||
sb (including the two bytes for the header itself, or L - 1 not counting the
|
||||
two bytes for the header). The higher four bits are set to 1011 (0xb) by the
|
||||
compressor for a compressed block, or to 0000 for an uncompressed block, but
|
||||
the decompressor only checks the most significant bit taking a 1 to signify a
|
||||
compressed block, and a 0 an uncompressed block.
|
||||
|
||||
So from the header we know how many compressed bytes we need to decompress to
|
||||
obtain the next 4kiB of uncompressed data and if we didn't want to decompress
|
||||
this sb we could just seek to the next next one using the length read from the
|
||||
header. We could then continue seeking until we reach the first sb overlapping
|
||||
@page.
|
||||
|
||||
In either case, we will reach a sb which we want to decompress.
|
||||
|
||||
Having dealt with the 16-bit header of the sb, we now have length bytes of
|
||||
compressed data to decompress. This compressed stream is further split into
|
||||
tokens which are organized into groups of eight tokens. Each token group (tg)
|
||||
starts with a tag byte, which is an eight bit bitmap, the bits specifying the
|
||||
type of each of the following eight tokens. The least significant bit (LSB)
|
||||
corresponds to the first token and the most significant bit (MSB) corresponds
|
||||
to the last token.
|
||||
|
||||
The two types of tokens are symbol tokens, specified by a zero bit, and phrase
|
||||
tokens, specified by a set bit.
|
||||
|
||||
A symbol token (st) is a single byte and is to be taken literally and copied
|
||||
into the sliding window (the decompressed data).
|
||||
|
||||
A phrase token (pt) is a pointer back into the sliding window (in bytes),
|
||||
together with a length (again in bytes), starting at the byte the back pointer
|
||||
is pointing to. Thus a phrase token defines a sequence of bytes in the sliding
|
||||
window which need to be copied at the current position into the sliding window
|
||||
(the decompressed data stream).
|
||||
|
||||
Each pt consists of 2 bytes split into the back pointer (p) and the length (l),
|
||||
each of variable bit width (but the sum of the widths of p and l is fixed at
|
||||
16 bits). p is at least 4 bits and l is at most 12 bits.
|
||||
|
||||
The most significant bits contain the back pointer (p), while the least
|
||||
significant bits contain the length (l).
|
||||
|
||||
l is actually stored as the number of bytes minus 3 (unsigned) as anything
|
||||
shorter than that would be at least as long as the 2 bytes needed for the
|
||||
actual pt, so no compression would be achieved.
|
||||
|
||||
p is stored as the positive number of bytes minus 1 (unsigned) as going zero
|
||||
bytes back is meaningless.
|
||||
|
||||
Note that decompression has to occur byte by byte, as it is possible that some
|
||||
of the bytes pointed to by the pt will only be generated in the sliding window
|
||||
as the byte sequence pointed to by the pt is being copied into it!
|
||||
|
||||
To give a concrete example: a block full of the letter A would be compressed
|
||||
by storing the byte A once as a symbol token, followed by a single phrase
|
||||
token with back pointer -1 (p = 0, therefore go back by -(0 + 1) bytes) and
|
||||
length 4095 (l=0xffc, therefore length 0xffc + 3 bytes).
|
||||
|
||||
The widths of p and l are determined from the current position within the
|
||||
decompressed data (cur_pos). We don't actually care about the widths as such
|
||||
however, but instead we want the mask (l_mask) with which to AND the pt to
|
||||
obtain l, and the number of bits (p_shift) by which to right shift the pt to
|
||||
obtain p. These are determined using the following algorithm:
|
||||
|
||||
for (i = cur_pos, l_mask = 0xfff, p_shift = 12; i >= 0x10; i >>= 1) {
|
||||
l_mask >>= 1;
|
||||
p_shift--;
|
||||
}
|
||||
|
||||
Note, that as usual in NTFS, the sb header, as well as each pt, are stored in
|
||||
little endian format.
