Which Linux distributions enable AT_RANDOM canary initialisation by default, and since which version?

You can test if you have AT_RANDOM canary initialisation enabled by running:

LD_SHOW_AUXV=1 /bin/true | grep AT_RANDOM

To the "belongs on superuser.com"/"off-topic" voters: This question is about buffer overflow protection, which is clearly programming related (hint: the name of this site). – knorv Apr 5 '10 at 8:35
Not really - buffer protection is certainly computer/software related, but knowing which distribution enables it by default is not programming related. – Douglas Leeder Apr 18 '10 at 10:16

Ubuntu uses a random canary by default. I believe all of the packages in apt are compiled with this canary, there maybe a few exceptions such as 3rd party repositories. I don't know if this specific AT_RANDOM canary is being used by anyone.
