habanalabs: fix bug in checking huge page optimization

2019-06-25T03:34:49+00:00

[ Upstream commit d724170160f800fa8dfd3c0cdebb8b093570b504 ] This patch fix a bug in the mmu code that checks whether we can use huge page mappings for host pages. The code is supposed to enable huge page mappings only if ALL DMA addresses are aligned to 2MB AND the number of pages in each DMA chunk is a modulo of the number of pages in 2MB. However, the code ignored the first requirement for the first DMA chunk. This patch fix that issue by making sure the requirement of address alignment is validated against all DMA chunks.

lkdtm/usercopy: Moves the KERNEL_DS test to non-canonical

2019-06-25T03:34:47+00:00

[ Upstream commit 2bf8496f6e9b7e9a557f65eb95eab16fea7958c7 ] The prior implementation of the KERNEL_DS fault checking would work on any unmapped kernel address, but this was narrowed to the non-canonical range instead. This adjusts the LKDTM test to match. Fixes: 00c42373d397 ("x86-64: add warning for non-canonical user access address dereferences") Signed-off-by: Kees Cook Signed-off-by: Sasha Levin

genwqe: Prevent an integer overflow in the ioctl

2019-06-11T10:19:18+00:00

commit 110080cea0d0e4dfdb0b536e7f8a5633ead6a781 upstream. There are a couple potential integer overflows here. round_up(m->size + (m->addr & ~PAGE_MASK), PAGE_SIZE); The first thing is that the "m->size + (...)" addition could overflow, and the second is that round_up() overflows to zero if the result is within PAGE_SIZE of the type max. In this code, the "m->size" variable is an u64 but we're saving the result in "map_size" which is an unsigned long and genwqe_user_vmap() takes an unsigned long as well. So I have used ULONG_MAX as the upper bound. From a practical perspective unsigned long is fine/better than trying to change all the types to u64.
