Hi,
Yesterday during a challenge we had to use the linux_dump_map plugin
to dump a process stack, and the documentation at
https://code.google.com/p/volatility/wiki/LinuxCommandReference23#linux_pro…
says it has the -p option to select a process.
However, as far as I can tell looking in the svn history, this plugin
never had the -p option. And it's definitely not working currently.
I've heard a confirmation that the option was working in version
2.2-rc1, so maybe it was a global option?
The reason I'm mailing this is because, if the -s is virtual memory,
would you not get possible overlap in areas? How do you know it dumped
the correct VMA? Note that every time I tried, I got the correct area.
Cheers,
Edwin

After some more research, I think it is a bug and the attached patch
hopefully fixes it.

Hi Edwin,
You're right, it looks like there were a few different issues with that
plugin. I applied a patch [1] similar to yours that should make things
easier. It now accepts -p, but also takes a --dump-dir argument instead of
--outfile. You can dump all VMAs from all processes, all VMAs from a
specific process (or multiple processes with -p 1,2,3) or a specific VMA
from a specific process. The output file name includes the task ID as well
as the VMA starting address. There's a summary printed to stdout to
minimize confusion.
For example:
Task VM Start VM End Length Path
---------- ---------- ---------- ---------- ----
1 0x08048000 0x0811d000 0xd5000 dumps/task.1.0x8048000.vma
1 0x0811e000 0x08124000 0x6000 dumps/task.1.0x811e000.vma
1 0x08124000 0x08125000 0x1000 dumps/task.1.0x8124000.vma
1 0x08125000 0x081b0000 0x8b000 dumps/task.1.0x8125000.vma
1 0xb7522000 0xb752e000 0xc000 dumps/task.1.0xb7522000.vma
Can you try the patch and let me know if it works for you?
Thanks,

Hi MHL,
The whole plugin is definitely much better now, and it works. Thanks!
Cheers,
Edwin
