ASLR / DEP for linux in I.MX6

JHY — Wed, 30 Sep 2015 02:57:20 GMT

Hi, experts.

I Have a question for security options for I.MX6.

ASLR(Address Space layout randomization)
DEP(Data Execution Prevention)

Those two features are available in linux kernel above 2.6.

Is it same to I.MX6 BSP?

It needs NX bit in CPU to excute DEP operation, and please confirm that compatibility of I.MX6.

Thank you.

Hello,

The mentioned options are supported as much as general Linux does.

The recent i.MX BSP is based on version 3.14.38 of the Linux kernel from
the official Linux kernel website (www.kernel.org ). It is enhanced with the
features provided by Freescale – mainly specific drivers are added.

As for general Linux features, concerned with ARM core – nothing specific.

Have a great day,
Yuri
