Ah, I see. Thanks. I guess the info here:
http://people.redhat.com/mingo/exec-shield/ANNOUNCE-exec-shield
is a bit outdated:
---
There is a new boot-time kernel command line option called exec-shield=,
which has 4 values. Each value represents a different level of security:
exec-shield=0 - always-disabled
exec-shield=1 - default disabled, except binaries that enable it
exec-shield=2 - default enabled, except binaries that disable it
exec-shield=3 - always-enabled
the current patch defaults to 'exec-shield=2'. The security level can also
be changed runtime, by writing the level into /proc:
echo 0 > /proc/sys/kernel/exec-shield
---
I noticed the current default value is actualy 1. Do the 0, 1, and 2
level still have the above meaning ?
Regards,
Christian
