I noticed there's been some activity recently with HARDENED_USERCOPY.
And I looked over how mm/usercopy.c was merged in from the grsecurity
patch. I'm curious about this TODO item:
Identify and extend HARDENED_USERCOPY to other usercopy functions
(e.g. maybe csum_partial_copy_from_user, csum_and_copy_from_user,
csum_and_copy_to_user, csum_partial_copy_nocheck?)
It doesn't look like anyone is working on this task right now. But it's not
obvious (to me) what needs to happen to make progress with this. Would this
be a good task to start off with?
Thanks
