Running auditd from Raspberry Pi (Raspbian)

Running auditd from Raspberry Pi (Raspbian)

[-- Attachment #1.1: Type: text/plain, Size: 1226 bytes --]

Hi, all 

From my Raspberry Pi machine (running Debian Wheezy distribution), I could see the kernel is built with audit enabled, and I could manage to install user-space audit client with the following command. 

pi@raspberrypi ~ $ sudo apt-get install auditd

However, when I tried to enable audit issuing the following commands it doesn’t seem to run properly.

pi@raspberrypi ~ $ sudo auditctl -l
No rules
pi@raspberrypi ~ $ sudo auditctl -a entry,always -S open
Error detecting machine type
pi@raspberrypi ~ $ sudo auditctl -a entry,always -F arch=armeb -S open
arch=armeb machine type not found

Can anyone tell me whether audit support ARM based linux systems?
Here’s my system information and thanks a lot for your help in advance!

pi@raspberrypi ~ $ sudo uname -a
Linux raspberrypi 3.18.11-v7+ #781 SMP PREEMPT Tue Apr 21 18:07:59 BST 2015 armv7l GNU/Linux

pi@raspberrypi ~ $ dpkg -l |grep audit
ii  auditd                                1:1.7.18-1.1                            armhf        User space tools for security auditing

Yes. It was added starting in 2.0.4 and was corrected several times.

That one is too old. You need a newer audit package.

Thanks a lot for your support. I will try with newer version and let you know how it goes!

Dear Steve,

I built auditctl from recent audit source and tried it again but I failed with the following errors. 

pi@raspberrypi ~/audit-2.4.4 $ sudo auditctl -e1 -b 102400
AUDIT_STATUS: enabled=1 flag=1 pid=2022 rate_limit=0 backlog_limit=320 lost=0 backlog=0
(reverse-i-search)`b': sudo auditctl -e1 -^C102400
pi@raspberrypi ~/audit-2.4.4 $ sudo src/auditctl -a exit,always -F arch=armeb -S clone
arch elf mapping not found
pi@raspberrypi ~/audit-2.4.4 $ sudo src/auditctl -a exit,always -S clone
Error detecting machine type

Would you help me with this?

Thanks a lot for your help again!

Regards, Kangkook

Did you add --with-arm to the ./configure line? Its disabled by default.

Re: Running auditd from Raspberry Pi (Raspbian)

[Kangkook Jee]

I added “—with-armeb” should it be just “—with-arm” ?

This following shows my configuration status.

pi@raspberrypi ~/audit-2.4.4 $ grep arm config.status
ac_cs_config="'--with-armeb'"
  set X /bin/bash './configure'  '--with-armeb' $ac_configure_extra_args --no-create --no-recursion

This time, I built with —with-arm option and tried again. It still fails but with different error message.


pi@raspberrypi ~/audit-2.4.4 $ grep arm config.status

If this works:

ausyscall armeb open

returns something like:

open               5
mq_open            274
openat             322
perf_event_open    364
open_by_handle_at  371

Then user space is working. Anything else would be kernel issues.
