po: Import pofiles and various build fixes.
Richard Jones [Fri, 19 Feb 2010 16:40:32 +0000 (16:40 +0000)]

Richard Jones [Fri, 19 Feb 2010 13:51:07 +0000 (13:51 +0000)]
hivexsh: Print hex bytes >= 0x80 correctly.
These were being interpreted as signed chars, and thus printed
as "
ffffff80" etc.
Richard Jones [Mon, 15 Feb 2010 15:55:38 +0000 (15:55 +0000)]
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.
Richard Jones [Fri, 5 Feb 2010 18:01:18 +0000 (18:01 +0000)]

Richard Jones [Fri, 5 Feb 2010 14:50:19 +0000 (14:50 +0000)]
hivex: Fix handling of inline VKs.
Richard Jones [Fri, 5 Feb 2010 13:47:32 +0000 (13:47 +0000)]
hivexsh: Set correct type for 'expandstring' values.
Richard Jones [Fri, 5 Feb 2010 12:59:43 +0000 (12:59 +0000)]
hivex: Documentation and cleanups.
Richard Jones [Fri, 5 Feb 2010 12:59:18 +0000 (12:59 +0000)]
hivex: Make limits into macros.
Richard Jones [Fri, 5 Feb 2010 12:57:53 +0000 (12:57 +0000)]
hivexsh: Remove unused variable.
This removes an unused variable left over by
commit
ab608f3948d903af64e814b2e67949a1a71d93a4.
Richard Jones [Thu, 4 Feb 2010 16:33:18 +0000 (16:33 +0000)]
hivex: Complete the implementation of adding child nodes.
Richard Jones [Thu, 4 Feb 2010 18:42:58 +0000 (18:42 +0000)]
hivex: More debugging around nk 'unknown2' field.
Richard Jones [Thu, 4 Feb 2010 17:59:11 +0000 (17:59 +0000)]
hivex: Check hash fields in lf/lh records.
Richard Jones [Thu, 4 Feb 2010 16:32:22 +0000 (16:32 +0000)]
hivexsh: del command: Fix error message.
Richard Jones [Thu, 4 Feb 2010 16:31:55 +0000 (16:31 +0000)]
hivexsh: lsval: Remove stray quotation mark.
Richard Jones [Thu, 4 Feb 2010 16:31:09 +0000 (16:31 +0000)]
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.
Richard Jones [Thu, 4 Feb 2010 16:29:32 +0000 (16:29 +0000)]
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.
Richard Jones [Thu, 4 Feb 2010 16:29:11 +0000 (16:29 +0000)]
hivex: More debug messages.
Richard Jones [Thu, 4 Feb 2010 16:28:26 +0000 (16:28 +0000)]
hivex: Documentation update.
ntreg_lf_record can have id "lf" (old-style hashes) or "lh" (new-
style hashes).
Richard Jones [Thu, 4 Feb 2010 16:27:58 +0000 (16:27 +0000)]
hivex: Some missing le32toh endianness conversions.
Richard Jones [Thu, 4 Feb 2010 14:12:04 +0000 (14:12 +0000)]
hivexsh: Document some peculiarities of the "cd" command.
Richard Jones [Wed, 3 Feb 2010 18:10:38 +0000 (18:10 +0000)]
hivex: Implement deleting child nodes.
Richard Jones [Thu, 4 Feb 2010 13:24:27 +0000 (13:24 +0000)]
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.
Richard Jones [Thu, 4 Feb 2010 13:26:04 +0000 (13:26 +0000)]
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).
Richard Jones [Wed, 3 Feb 2010 18:09:52 +0000 (18:09 +0000)]
hivex: Minimal registry example.
This is the smallest registry you can make and still have it
load correctly in Windows regedit.
Richard Jones [Wed, 3 Feb 2010 18:04:31 +0000 (18:04 +0000)]
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.
Richard Jones [Wed, 3 Feb 2010 17:59:03 +0000 (17:59 +0000)]
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.
Richard Jones [Mon, 18 Jan 2010 11:08:56 +0000 (11:08 +0000)]
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.
Richard Jones [Wed, 3 Feb 2010 17:35:53 +0000 (17:35 +0000)]
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)
Richard Jones [Wed, 3 Feb 2010 17:50:51 +0000 (17:50 +0000)]
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.
Richard Jones [Wed, 3 Feb 2010 17:48:37 +0000 (17:48 +0000)]
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.
Richard Jones [Wed, 3 Feb 2010 17:45:20 +0000 (17:45 +0000)]
Document that this flag is clear for default keys.

Misc documentation and gitignore update.
Richard Jones [Wed, 3 Feb 2010 17:41:15 +0000 (17:41 +0000)]
Move htole*/le*toh macros into a separate header file.
This allows us to reuse these macros in hivexsh later.
Richard Jones [Fri, 29 Jan 2010 19:12:34 +0000 (19:12 +0000)]
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.
Richard Jones [Fri, 29 Jan 2010 12:18:30 +0000 (12:18 +0000)]
hivex: Add 'hivexsh' program (shell for navigating registry hives).
Richard Jones [Fri, 29 Jan 2010 14:56:13 +0000 (14:56 +0000)]
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).

This was missing. It only worked because we test on a little
endian platform.

Richard Jones [Tue, 19 Jan 2010 12:22:10 +0000 (12:22 +0000)]
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.
Richard Jones [Tue, 19 Jan 2010 10:06:00 +0000 (10:06 +0000)]
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: 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

paper says.
