Retguard will start using sections named ".openbsd.randomdata.retguard.*" and not just ".openbsd.randomdata.retguard". Accept both in the kernel ldscripts so that they're placed together between the __retguard_{start,end} symbols.

timecounting: remove incomplete PPS support

3 years ago

On systems without xonly mmu hardware-enforcement, we can still mitigate against classic BROP with a range-checking wrapper in front of copyin() and copyinstr() which ensures the userland source doesn't overlap the main program text, ld.so text, signal tramp text (it's mapping is hard to distinguish so it comes along for the ride), or libc.so text. ld.so tells the kernel libc.so text range with msyscall(2). The range checking for 2-4 elements is done without locking (because all 4 ranges are immutable!) and is inexpensive.
