hivex: Newer Python versions want parentheses around arguments of "print"
hivex: Fix building on platforms without O_CLOEXEC such as FreeBSD
hivex: Don't build static library, .so.* symlinks for Python bindings
2011-08-16 Alex Nelson <ajnelson@cs.ucsc.edu>
hivexml: Add root attribute to the root node
New feature: If the root node of the XML root is the hive root node,
denote with attribute/value root="1".
2011-08-15 Richard W.M. Jones <rjones@redhat.com>
ruby: Test against locally built library.
Prevent warning about unused variable in test.
Fix incorrect printf format specifier in error string.
hivex(3): Fix link to CSS.
Version 1.3.0.
Add Ruby bindings.
header: Fix including just <hivex.h>.
Also this adds a regression test so we don't break it in future.
2011-08-13 Alex Nelson <ajnelson@cs.ucsc.edu>
Report last-modified time of hive root and nodes
The infrastructure for modified-time reporting has been essentially
unused. These changes report the registry time by treating the
time fields as Windows filetime fields stored in little-Endian
(which means they can be treated as a single 64-bit little-Endian
integer).
This patch adds to the hivex ABI:
* int64_t hivex_last_modified (hive_h *)
* int64_t hivex_node_timestamp (hive_h *, hive_node_h)
These two functions return the hive's last-modified time and
a particular node's last-modified time, respectively. Credit
to Richard Jones for the ABI suggestion, and for the tip on
Microsoft's filetime time span.
hivexml employs these two functions to produce mtime elements
for a hive and all of its nodes, producing ISO-8601 formatted
time.
A lot of code cleanup by RWMJ.
2011-08-12 Richard W.M. Jones <rjones@redhat.com>
Version 1.2.8.
Pushed and pulled translations from Transifex.
2011-08-12 Hilko Bengen <bengen@hilluzination.de>
More changes needed separate builddir
This patch hopefully fixes building and installing the OCaml bindings
both in-tree and out-of-tree.

More changes needed separate builddir
Here's the fix for perl. Both in-tree and out-of-tree build and install
worked.

hivex: A few tweaks to enable building in a separate directory
A couple of fixes by RWMJ so it still works in the same directory case.

perl: Fix CCFLAGS on Perl 5.14.
A change to ExtUtils::CBuilder in Perl 5.14 causes CCFLAGS to
completely replace, rather than appending, the C flags.
The unfortunate consequence of this is that vital flags such as
-D_FILE_OFFSET_BITS=64 are missing. For 32 bit code, this means you
get binary-incompatible code that completely fails to load.
For further analysis see:
http://www.nntp.perl.org/group/perl.perl5.porters/2011/04/msg171535.html
This commit changes CCFLAGS so that it appends to the existing
$Config{ccflags} instead of replacing it. On earlier versions of Perl
this means we get two copies of the flags, which is unfortunate but
should be safe.
Also, ignore MYMETA.yml file produced by Perl 5.14.
2011-07-11 Michael Huang <Michael.Huang@visionsolutions.com>
Close the file descriptor along the writable path.
Since the file has been completely read into memory, there is no
reason to keep the file descriptor open.
2011-06-29 Richard W.M. Jones <rjones@redhat.com>
Sort m4/.gitignore file.

maint: add cfg.mk to prepare for syntax-check tests
* cfg.mk: New file, to tell maint.mk which syntax-checks to skip
for now, where .gnulib/ is, to exempt images/minimal from
one of the tests and to exempt sh/hivexsh\.pod from another.
Also exempt lib/gettext.h from sc_useless_cpp_parens.
2011-06-28 Jim Meyering <meyering@redhat.com>
maint: remove rule that generated po/POTFILES.in
* Makefile.am (all-local): Remove rule. It would put many
files in po/POTFILES.in that contain no translatable diagnostic.
build: update gnulib submodule to latest
maint: remove spaces before TAB
* perl/typemap: Remove spaces-before-TAB.
maint: avoid using test's -a and -o operators; they are not portable
* configure.ac: use "test C1 && test C2", not "test C1 -a C2";
* autogen.sh: Likewise.
* sh/hivexget: Use "test C1 || test C2", not "test C1 -o C2"
maint: use "test x = x", not "test x == x"
* autogen.sh: Using "test x = x" is more portable.
maint: remove trailing blanks
maint: remove now-unnecessary #ifdef HAVE_BYTESWAP_H guard
* lib/byte_conversions.h: Remove #ifdef HAVE_BYTESWAP_H guard.
With gnulib, we're guaranteed to have that header file.
* bootstrap (modules): Use the byteswap module.
maint: remove definition of O_CLOEXEC, ...
now that we're using gnulib's fcntl module, which ensures
that we use a conforming <fcntl.h>.
* lib/hivex.c (O_CLOEXEC): Remove definition.
* bootstrap (modules): Add fcntl for its guaranteed definition
of O_CLOEXEC.
maint: normalize to exactly one newline at EOF
* .tx/config: Remove trailing empty line.
* images/Makefile.am: Likewise.
* sh/example1: Add newline at EOF.
* sh/example2: Likewise.
* sh/example3: Likewise.
* sh/example4: Likewise.
* sh/example5: Likewise.
maint: update po/POTFILES.in
* po/POTFILES.in: Reduce list of files with translatable messages
to match reality.
maint: remove definitions of PRId64 and PRIu64, ...
now that we're using gnulib's inttypes module, which ensures
that we use a conforming <inttypes.h>.
* bootstrap (modules): Add inttypes.
* generator/generator.ml (generate_perl_xs) [PRId64, PRIu64]:
Don't define these symbols. Instead, ...
Include <inttypes.h>.
maint: remove unnecessary test-before-free
* lib/hivex.c (hivex_node_set_value): Remove unnecessary
test-before-free.

ocaml: Really fix 'make install' rule.
This fixes commit b8ad15031cacf910634b4f4f4632232949c4acd2
and commit f408b757b1d75429fae5fa7630a4fc5451844de7.
ocaml: Set package name when installing native bindings.
This fixes commit b8ad15031cacf910634b4f4f4632232949c4acd2.
Version 1.2.7.
Update gnulib to latest version.
hivexregedit: Add --unsafe-printable-strings option.
2011-05-13 Richard W.M. Jones <rjones@redhat.com>
hivex_root: Return errno == HIVEX_NO_KEY when root key is missing.
Previously we returned errno == ENOKEY. However this was an
unfortunate choice of error code since it is not defined in POSIX. As
a result it is missing on several platforms.
HIVEX_NO_KEY is defined as ENOKEY on platforms where this symbol
exists (thus maintaining backwards ABI compatibility), and defined as
another POSIX error code otherwise.

ocaml: Use libtool to get correct library to build OCaml tests.
See this thread:
https://www.redhat.com/archives/libguestfs/2011-May/thread.html#00015
Thanks to Hilko Bengen and Török Edwin for coming up with this fix.
Version 1.2.6.
build: Workaround broken libtool.
Same as this error:
https://www.redhat.com/archives/libguestfs/2011-April/msg00042.html
https://www.redhat.com/archives/libguestfs/2011-May/msg00041.html
We don't know why latest libtool is so obviously broken, but this
works around the problem.
bootstrap: Force gnulib-tool --libtool option.
This forces the recent gnulib to generate a libgnu.la file. Otherwise
it appears to default to --no-libtool which doesn't generate one.
configure: AC_PROG_LIBTOOL -> AM_PROG_LIBTOOL.
Unclear if this makes any difference.
Update gnulib.

Found it.
Now "make check" completes successfully on Sparc and PowerPC.

configure: Use Python platform-dependent site-packages.
This updates commit b808c875a34e62fcdf360534f923d6030590ff44.
2011-05-09 Hilko Bengen <bengen@hilluzination.de>
Use Python's distutils to determine include and site-packages directories.
The code has been taken from specifically ac_python_devel.m4 published
at <http://ac-archive.sf.net/>, it has turned out to be less
error-prone on my Debian system.
Don't rely on OCaml native compiler for tests
This should make it possible to build useful OCaml bindings on
architectures other than i386 and amd64 (Debian bug #589809).
2011-04-28 Richard W.M. Jones <rjones@redhat.com>
Include generator in the tarball.

hivex/python fix for i386 integer size issue
Hi,
While working on Debian packages of hivex 1.2.5, I came across a test
failure for the Python bindings with Python 2.7 on the i386
architecture. (The tests ran fine on amd64.)
,----
| $ make -C python check
| make[1]: Entering directory `/home/bengen/src/deb/hivex/hivex.git/python'
| 010-import.py
| 020-open.py
| 021-close.py
| 200-write.py
| python: hivex-py.c:52: get_handle: Assertion `obj' failed.
`----
I narrowed this down to hivex-py.c:py_hivex_node_add_child():
The call
,----
| PyArg_ParseTuple (args, (char *) "OLs:hivex_node_add_child",
| &py_h, &parent, &name)
`----
results in `py_h' set to NULL, though Python's documentation claims that
this cannot happen. I think this happens because `parent' is declared a
`long int', but "L" in the format string corresponds to a `long long'.
On amd64, they have the same size, but on i386 they don't, so the
PyObject pointer is written to the wrong address.
Please consider applying the patch below which just changes the format
string. After regenerating hivex-py.c, I have successfully tested the
1.2.5 code base on both architectures.
Cheers,
-Hilko

maint: Split long lines.
* lib/hivex.c: Split lines longer than 80 columns.
2011-04-13 Richard W.M. Jones <rjones@redhat.com>
Version 1.2.5.
Updated PO files.
Remove no longer used internal function utf16_string_len_in_bytes.
hivex_value_multiple_strings: Don't read uninitialized data.
If hivex_value_multiple_strings was given a value which had an odd
length or if the data in the value was unterminated,
hivex_value_multiple_strings could read uninitialized data.
Potentially (although very unlikely) this could cause a
non-exploitable segfault in the calling program.
Handle odd-length "UTF16" strings.
If the length of the buffer is not even, then this would read a byte
of uninitialized data. Fix the length check to avoid this.
Return real length of buffer from hivex_value_value.
In real registries, often the length declared in the header does not
match the length of the block. In this case hivex_value_value would
only allocate a value with a size which is the shorter of the two
length values, which is correct and safe.
However user code could do:
buf = hivex_value_value (h, v, &t, &len);
memcpy (somewhere, buf, len);
which would copy uninitialized data.
If hivex_value_value truncates a value like this, we also need to
return the shorter length to the user as well.
Really fix the case where a UTF-16 string contains junk after the string.
The previous commit b71b88f588f8660935a7d462e97b84aa2d669249 attempted
to fix this, but got the test the wrong way round so the length would
never be shorter.
2011-04-12 Richard W.M. Jones <rjones@redhat.com>
Fix use-after-free in hivex_close.
Found using valgrind.
2011-04-02 Richard W.M. Jones <rjones@redhat.com>

ocaml: Fix segfault in Hivex.value_value binding.
2010-12-02 Richard W.M. Jones <rjones@redhat.com>
Version 1.2.4.
2010-11-28 Richard W.M. Jones <rjones@redhat.com>
Python bindings.
2010-08-27 Richard Jones <rjones@redhat.com>
Version 1.2.3.
build: Don't warn about 'long long'.
We have to allow this, even though it's a GCC extension.
This is a port of libguestfs commit 0c0976496dafda4d172c5a7fc787d6a87d5bce8d.
2010-08-27 Geert Warrink <geert.warrink@onsnet.nu>
Add Dutch translations (RHBZ#624455).
2010-08-13 Matthew Booth <mbooth@redhat.com>
Add debug output to hivex_close.
2010-07-12 Richard Jones <rjones@redhat.com>
Don't try to process junk after a string value as UTF-16.
Thanks to Hilko Bengen for characterizing the issue and
providing an initial version of this patch.
2010-07-12 Hilko Bengen <bengen@hilluzination.de>
Call iconv_close along error path out of function.
2010-07-11 Richard Jones <rjones@redhat.com>
perl: Fix generated XS code for value_dword binding.
Thanks to Hilko Bengen for spotting the problem.
2010-07-08 Conrad Meyer <cemeyer@cs.washington.edu>
Add hivex_set_value API call, and ocaml and perl bindings, and tests.
2010-06-13 Richard Jones <rjones@redhat.com>
hivex_value_type: Returns -1 on error. Fix documentation.
2010-05-13 Richard Jones <rjones@redhat.com>
Include a test for regimport of values containing backslash chars.
2010-04-30 Richard Jones <rjones@redhat.com>
regedit: Fix documentation for CurrentControlSet (thanks Yuval Kashtan).
2010-04-28 Richard Jones <rjones@redhat.com>
Version 1.2.2.
regedit: Add implicit nul-termination when importing strings.
When you import a string value like:
"Foo"="Bar"
using Windows regedit program, implicit nul-termination is added
to the value (not the key), so what is stored in the value would
be something like:
hex(1):42,00,61,00,72,00,00,00
where two of the trailing zero bytes come from the implicit
terminator. This corrects the reg_import function so it works
the same way.
2010-04-20 Richard Jones <rjones@redhat.com>
Remove checks for Test::Pod and Test::Pod::Coverage.
Although these modules are optionally used by the Perl tests,
they aren't necessary and won't break the build if they are not
there. These modules aren't available in RHEL 5. Therefore
remove these checks.
2010-04-03 Richard Jones <rjones@redhat.com>
Add a linker script to limit visibility to exported symbols.
2010-04-03 TJ <linux@tjworld.net>
Remove explicit dependency on ncurses.
Spelling: reencode -> re-encode.
2010-04-02 TJ <linux@tjworld.net>
Add CLEANFILES rules.
2010-04-01 Yulia <ypoyarko@redhat.com>
New Russian translation (RHBZ#578347).
2010-03-30 Richard Jones <rjones@redhat.com>
Update PO files.
Add maintainer rule for updating the website.
hivexml: Fix path so HTML documentation is generated correctly.
Prepare for version 1.2.1.
hivexregedit: Low-level tool for merging and export in regedit format.
Win::Hivex::Regedit module for importing and exporting regedit format files.
hivexsh: '-f' option takes an argument (found by Marko Myllynen).
2010-03-29 Richard Jones <rjones@redhat.com>
Zero all new block allocations.
Make sure all new block allocations (from allocate_block)
are zeroed. It can happen that junk from previous hive pages
can end up in new block allocations, if the hive previously
shrank.
(Thanks to Marko Myllynen for finding an example where this
happened).
Increase HIVEX_MAX_VALUES from 1000 to 10000.
I was sent a genuine Windows XP hive by Marko Myllynen which
had a key with > 1000 values attached.
2010-03-26 Richard Jones <rjones@redhat.com>
Increase HIVEX_MAX_SUBKEYS to 15000.
Windows 7 registry has a hive key which contains 11908 subkeys,
larger than the existing limit (10000). The key is:
HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\SideBySide\Winners
hivex: Add debugging message when returning ERANGE error.
hivexsh: Fix building of HTML-format manpages.
2010-03-25 Richard Jones <rjones@redhat.com>
perl: Fix $h->value_value method when returning an empty value.
Previously this didn't correctly return an empty registry
value. In this case the length argument to newSVpv would
be 0 which tells Perl to try to calculate the length (we
want newSVpvn instead).
Fix generation of po/POTFILES.in.
Contains some obsolete code copied in from libguestfs, and we
need to exclude Perl 'blib' files.
perl: Small fix to 006-pod-coverage test.
Some code copied over from libguestfs, fixed.
perl: Fix $h->value_type and $h->value_value methods.
These were passing the type & len arguments the wrong way round
to the C function, resulting in data corruption in the returned
values.
2010-03-08 Richard Jones <rjones@redhat.com>
Fix documentation for Win::Hivex->open
2010-03-01 Richard Jones <rjones@redhat.com>
RHEL 5: Fixes for old version of OCaml in EPEL 5.
Prepare for version 1.2.0.
Fix hivexsh_SOURCES.
Update PO files.
2010-03-01 Daniel Cabrera <logan@fedoraproject.org>
Update Spanish translations (RHBZ#569178).
2010-03-01 Richard Jones <rjones@redhat.com>
Update PO files.
2010-03-01 Piotr Drąg <piotrdrag@gmail.com>
Update Polish translations (RHBZ#502533).
2010-02-26 Richard W.M. Jones <rjones@redhat.com>
NO Python bindings - ran out of time.
This commit disables parts of the build related to Python
and notes in the README that we didn't have time to finish
Python bindings.
generator: Perl bindings.
This also adds a small test suite for the Perl bindings.
generator: Clarify LGPLv2 boilerplate.
More documentation in README file.
hivexsh: Fix compilation on 32 bit machines.
2010-02-25 Richard Jones <rjones@redhat.com>
Remove bogus msgstr from kn.po.
2010-02-24 Richard Jones <rjones@redhat.com>
generator: Add OCaml bindings.
Also we tighten up the definition of hivex_close (it disposes of handles)
and hivex_node_get_child (unusual "not found" non-error condition).
This also adds tests of the OCaml bindings.
Add build framework for OCaml, Perl, Python bindings.
(No bindings are actually built, this just adds the build, test
and generator framework for them).
configure: Comment out Ruby, Java, Haskell detection.
We will not be implementing bindings for Ruby, Java or Haskell
unless someone pitches in to do the work. Therefore comment out
the code which detects these languages in the configure script.
(This leaves OCaml, Perl, Python, which we will be writing
bindings for).
Create separate toplevel directories for hivexsh and hivexml.
Rename hivex/ -> lib/
Move test images to images/ and add a large, generated test image.
Previously we had one minimal test image. This was located in
hivex/t (a subdirectory of the main library).
This adds a large, procedurally generated test image. Because
this needs to be built using hivex code, and because subdirectories
are built before the parent directory by automake, we have to
also move the directory location to a top-level directory called
images/.
2010-02-24 Shankar Prasad <svenkate@redhat.com>
Added Kannada translation (RHBZ#567860).
2010-02-23 Richard Jones <rjones@redhat.com>
hivex: Fix allocations that may move C heap buffer.
When heavily extending existing hive files, the malloc-allocated
in-memory copy of the hive may be moved when we reallocate it
(to increase its size). However we didn't adjust existing
pointers to cope with this, so sometimes you could get a segfault.
This patch fixes the issue by adjusting pointers as necessary
after calling (directly or indirectly) to the allocate_block
function.
With this patch I was able to allocate 10,000's of blocks in
a deeply nested hive structure without any problems being reported
by valgrind.
Link gnulib in to the hivex library, not end-user programs.
Gnulib should be statically linked into the hivex library, so
it gets included into end-user programs automatically. Otherwise
end-user programs would have to link explicitly with gnulib.
2010-02-22 Richard Jones <rjones@redhat.com>
generator: More minor formatting adjustments to POD documentation.
generator: Minor adjustments to the C POD documentation.
Add a generator for generating bindings to other languages.
At the moment the generator just generates the C header file
and C POD documentation. This just so we can compare the existing
hand-written code with the generated code to make sure that our
description of the API within the generator is correct.
Remove bogus reference to src/ directory which no longer exists.
Update copyright notice and change libguestfs to hivex.
Version 1.1.2
Install hivex.h in $includedir.
Version 1.1.1.
Also some minor fixes to the build system.
2010-02-19 Richard Jones <rjones@redhat.com>
Move README, LICENSE files to the toplevel directory.
gnulib: Remove some unused modules.
Version 1.1.0
po: Import pofiles and various build fixes.
Sort and complete m4/.gitignore file.
Add gettext.h, omitted from earlier import.
gnulib: Include xstrtol, xstrtoll modules.
These were omitted from the earlier code import from libguestfs.
Add html/ directory, include POD CSS.
hivexsh: Print hex bytes >= 0x80 correctly.
These were being interpreted as signed chars, and thus printed
as "ffffff80" etc.
Remove some unused variables.
Since we have to compile with -Wno-unused-variables, we don't
spot unused variables in code. I found these by compiling the
code in Ubuntu.
Add scripts to EXTRA_DIST.
hivex: example6: Don't double backslashes.
hivex: example6: Hypothetical addition of keys for viostor.
hivex: Fix handling of inline VKs.
hivexsh: Set correct type for 'expandstring' values.
hivex: Documentation and cleanups.
hivex: Make limits into macros.
hivexsh: Remove unused variable.
This removes an unused variable left over by
commit ab608f3948d903af64e814b2e67949a1a71d93a4.
hivex: Complete the implementation of adding child nodes.
hivex: More debugging around nk 'unknown2' field.
hivex: Check hash fields in lf/lh records.
hivexsh: del command: Fix error message.
hivexsh: lsval: Remove stray quotation mark.
hivexsh: cd command: fix error handling
The error behaviour of hivex_node_get_child is subtle, so the 'cd'
command wouldn't always report errors correctly. This fixes it.
hivex: allocate_block should update valid block bitmap.
The internal allocate_block() function wasn't updating the bitmap,
so if you revisited a block which you had allocated in the same
session, you could get an EFAULT error.
hivex: More debug messages.
hivex: Documentation update.
ntreg_lf_record can have id "lf" (old-style hashes) or "lh" (new-
style hashes).
hivex: Some missing le32toh endianness conversions.
hivexsh: Document some peculiarities of the "cd" command.
hivex: Implement deleting child nodes.
hivex: Add flags argument to internal get_children() function.
When we later call get_children to visit the intermediate
ri/lf/lh records, we have already deleted the subkey nk-records,
so checking that those nk-records are still valid is not very
helpful.
This commit adds a flag to turn these checks off.
hivex: Don't die on valid registries which have bad declared data lengths.
Some apparently valid registries contain value data length
declarations which exceed the allocated block size for the
value.
Previously the code would return EFAULT for such registries.
However since these appear to be otherwise valid registries,
turn this into a warning and just use the allocated block size
as the data length (in other words, truncate the value).
hivex: Minimal registry example.
This is the smallest registry you can make and still have it
load correctly in Windows regedit.
hivexsh: Add 'setval' and 'commit' commands.
This adds the 'setval' and 'commit' commands to the hivex shell.
Also adds some example scripts showing use of these.
hivex: Begin implementation of writing to hives.
This implements hivex_node_set_values which is used to
delete the (key, value) pairs at a node and optionally
replace them with a new set.
This also implements hivex_commit which is used to commit
changes to hives back to disk.
hivex: Add HIVEX_OPEN_WRITE flag to allow hive to be opened for writing.
If this flag is omitted (as in the case for all existing callers)
then the hive is still opened read-only.
We add a 'writable' flag to the hive handle, and we change the way
that the hive file (data) is stored. The data is still mmapped if
the file is opened read-only, since that is more efficient and allows
us to handle larger hives. However if we need to write to the file
then we have to read it all into memory, since if we had to extend the
file we need to realloc that data.
Note the manpage section L</WRITING TO HIVE FILES> comes in a later
commit.
Tools for analyzing and reverse engineering hive files.
This commit is not of general interest. It contains the tools which
I used to reverse engineer the hive format and to test changes.
Keeping these with the rest of the code is useful in case in future
we encounter a hive file that we fail to modify.
Note that the tools are not compiled by default. You have to compile
each explicitly with:
make -C hivex/tools <toolname>.opt
You will also need ocaml-extlib-devel and ocaml-bitstring-devel.
hivexsh: Change some exit(1) -> exit(EXIT_FAILURE)
hivexsh: Only print final \n when interactive.
When hivexsh was called non-interactively, it would print an
annoying extra line. Only print this line if we are being
used interactively.
hivexsh: Change handling of prompt argument to rl_gets()
Make the result of isatty into a global variable (is_tty).
Change the rl_gets() function so it takes the prompt string
instead of a "display prompt?" flag. rl_gets() then consults
the global to find out if it should display the prompt at all.
Document that this flag is clear for default keys.
Misc documentation and gitignore update.
Move htole*/le*toh macros into a separate header file.
This allows us to reuse these macros in hivexsh later.
hivex: Reimplement hivexget as a simple shell script.
hivexget is currently a large C program. Now that we have hivexsh
(the shell) we can reimplement hivexget as a simple bash script that
calls out to hivexsh.
hivex: Add 'hivexsh' program (shell for navigating registry hives).
Set locale in C programs so l10n works (RHBZ#559962).
This commit adds the calls to setlocale &c to all of the current
C programs.
It also adds l10n support to hivexget and hivexml which lacked them
previously.
To test this, try:
LANG=pa_IN.UTF-8 guestfish --cmd-help
(You can only do this test after installing the package, or at
least the 'pa.mo' mo-file in the correct place).
hivex: Const-correctness fix on header_checksum (thanks Jim Meyering).
hivex: Update some previously unknown nk-record fields.
Update these fields with what we found out from reverse engineering
the file. Also bring the unknownX field names into line with
visualizer.ml.
hivex: Fix calculation of block size for vk data blocks.
hivex: Display incorrect block size as unsigned in an error message.
hivex: display bad block offset in hex
hivex: hive type in vk-record is an unsigned 32 bit int
hivex: Add missing le32toh conversion around field access.
This was missing. It only worked because we test on a little
endian platform.
hivex: Clarify some more fields.
Taken from sentinelchicken.com documentation.
hivex: Modify children/values functions to return intermediate blocks.
Modify the functions that return child subnodes and values so they
can also be used to return a list of the intermediate blocks. This
is so we can delete those intermediate blocks (in a later commit).
We also introduce an offset_list structure which is used for collecting
lists of offsets, ie. lists of nodes, values or blocks.
Note that this commit should not change the semantics of the code.
hivex: Add value_any callback to the visitor.
The visitor currently contains lots of value_* callbacks, such as
value_string which is called back when the value has type string.
This is fine but it makes it complicated to deal with the case where
you just want to see 'a value', and don't care about its type.
The value_any callback allows visitors to see values generically.
hivex: Move header checksum code into a function.
This function can be reused later.
hivex: page 'offset_next' field is really 'page_size'.
The documentation, as usual, is contradictory. However this
field is definitely the page size in all observed registries.
Furthermore the following field marked 'unknown' is always
zero, although this contradicts what the sentinelchicken.com
paper says.
hivex: Collect more statistics about registries.
hivex: Store filename in hive handle.
hivex: Various improvements in header parsing, thanks to better documentation.
hivex: Print header fields. Print all offsets in hex (in debug output).
hivex: Reenable checksum calculations, but don't check result.
hivex: Update documentation.
hivex: Send all debug messages to stderr.
hivex: Remove stray debugging message.
hivex: Documentation: Add environment variables section.
hivex: Whitespace change.
hivex: Move STR* macros into C file.
Don't pollute the public header file with these macros.
hivex: Small updates to the documentation.
