I'm trying to figure out if the stock kernels for Centos-6 and/or Centos-7
have ExecShield compiled in, and if so, if it is turned on by default.
On my local C7 box I've been looking at/for indicators without a lot of
success:
/usr/lib/sysctl.d/00-system.conf. does not mention ExecShield at all.
/proc/sys/kernel has no entries for exec_shield
no mention of execshield in any of the files in /etc/grub.d
So, as far as I can see, there are no settings that I would expect to
force ExecShield to an ON setting.
I DO see, in /proc/sys/kernel, a file named randomize_va_space, and it
contains a value of "2".
I've been googling (well, actually DuckDuckGo-ing) and most of the articles
I find regarding ExecShield are 3-10 years old.
I'd appreciate pointers/guides/info on ExecShield in C6 or C7.
thanks in advance!
