have heap randomization enabled. This patch enables it.Same as the previous patch - this is one of options, that users =20 select according to their needs. If any specific distribution enables =20 this option by default in their kernels, they can do this too, don't think =20 this is critical enough to patch the defconfig.
I think that the matter is not being critical or not, but of =20 including a sane default as the kernel should be a place for best-=20 current-practices.
Just because users/distros can change it doesn't mean it's =20 pointless to discuss what default is sane, and make changes if the current default isn't.
Exactly my point.
For security-related options it's usually best to default to the more secure state, especially since the option description talks about it being needed mainly for libc5 compatibility -- did libc5 ever even =20 exist for powerpc?
I don't know, but even Debian's very ancient distributions all came =20 with libc6 on powerpc.
The only reason it was turned on in the first place was likely the "default y", which in turn is there to avoid breaking old x86 distros.
Exactly. Agreed 100%.
