Hello,
Sorry for taking so long to respond...
There are a couple issues:
1) You need to use dwarfump from
, not the os x supplied
dwarfdump for Linux support.
2) You can get System.map values from a few places. First, check if
the source distributed for your kernel has it. Second, see if the
phone exports /proc/kallsyms. If neither of those work then we will
have to find another solution.
Thanks,
Andrew

Thanks again Andrew for the assistance and for the
Makefile. So here a brief
summary for creating the Android profile, following the linux example here
(
https://code.google.com/p/volatility/wiki/LinuxMemoryForensics)
DISCLAIMER: I'm using a Mac OS X system.
- I modified the Makefile sent by Andrew, placed under
volatility/tools/linux/Makefile, adding the options for cross-compiling as
from the LiME kernel module. Basically the modifications are the following:
CCPATH :=
/path/to/android-ndk/toolchains/arm-linux-androideabi-4.4.3/prebuilt/darwin-x86/bin
dwarf: module.c
$(MAKE) ARCH=arm CROSS_COMPILE=$(CCPATH)/arm-linux-androideabi- -C $(KDIR)
CONFIG_DEBUG_INFO=y M=$(PWD) modules
- The last instruction of the makefile "dwarfdump -di module.ko >
module.dwarf" was originally with -di option. But -d appears to be not a
valid option anymore. Checking the man page, the alternatives for debugging
options are the following
--debug-abbrev, --debug-aranges, --debug-frame[=OFFSET],
--debug-info[=OFFSET], --debug-inlined, --debug-line[=OFFSET],
--debug-macinfo[=OFFSET], --debug-pubnames[=PATTERN],
--debug-pubtypes[=PATTERN], --debug-str
debug-info is the default (which looking at the output of "head
module.dwarf" seems to be the correct one), so i tried just to remove the -d
and also to put --debug-info without any offset value, but this is what I
get as content of the module.dwarf file
hydra:linux paco$ cat module.dwarf
----------------------------------------------------------------------
File: module.ko (arm)
----------------------------------------------------------------------
.debug_info contents:
< EMPTY >
- The last step to make the profile is to zip the module.dwarf file and the
System.map of the kernel. After searching around, I found that System.map
file for android is /proc/kallsyms (probably you all already knew it, but I
didn't know this :) ).
Attached the make file I used, if all the rest of the steps I did are right,
it's missing the right debug option for the dwarfdump command. I've tried
also the others but no one seems to give the right output. Any tips on this?
Thanks

Hello,
We are currently testing a stripped down Makefile to help people
compiling for different kernels than the one for the system they are
on (which includes Android). Can you please try the attached makefile?
You will need to change the KDIR varabile to point to your kernel
headers or source.
