Linus Torvalds kicked off the development of Linux kernel 4.15 last week when he announced the first Release Candidate milestone, which contained most of the changes that will land in the final version, due for release next year. And now he announces the second RC, which is slightly bigger that than the first one. Besides the usual bug fixes and security patches, it would appear that Linus Torvalds is in the process of getting some kernel address-space layout randomization (ASLR) leaks plugged from the Linux 4.15 kernel, and the first step took in this direction was to hash any pointers printed by “%p’ as default.
