[PATCH 5.16 v2] binfmt_elf: Avoid total_mapping_size for ET_EXEC

by Kees Cook

Partially revert commit 5f501d555653 ("binfmt_elf: reintroduce using MAP_FIXED_NOREPLACE"). At least ia64 has ET_EXEC PT_LOAD segments that are not virtual-address contiguous (but _are_ file-offset contiguous). This would result in giant mapping attempts to cover the entire span, including the virtual address range hole. Disable total_mapping_size for ET_EXEC, which reduces the MAP_FIXED_NOREPLACE coverage to only the first PT_LOAD: $ readelf -lW /usr/bin/gcc ... Program Headers: Type Offset VirtAddr PhysAddr FileSiz MemSiz ... ... LOAD 0x000000 0x4000000000000000 0x4000000000000000 0x00b5a0 0x00b5a0 ... LOAD 0x00b5a0 0x600000000000b5a0 0x600000000000b5a0 0x0005ac 0x000710 ... ... ^^^^^^^^ ^^^^^^^^^^^^^^^^^^ ^^^^^^^^ ^^^^^^^^ File offset range : 0x000000-0x00bb4c 0x00bb4c bytes Virtual address range : 0x4000000000000000-0x600000000000bcb0 0x200000000000bcb0 bytes Ironically, this is the reverse of the problem that originally caused problems with ET_EXEC and MAP_FIXED_NOREPLACE: overlaps. This problem is with holes. Future work could restore full coverage if load_elf_binary() were to perform mappings in a separate phase from the loading (where it could resolve both overlaps and holes).

[PATCH v4] x86/sgx: Free backing memory after faulting the enclave page

by Jarkko Sakkinen

There is a limited amount of SGX memory (EPC) on each system. When that memory is used up, SGX has its own swapping mechanism which is similar in concept but totally separate from the core mm/* code. Instead of swapping to disk, SGX swaps from EPC to normal RAM. That normal RAM comes from a shared memory pseudo-file and can itself be swapped by the core mm code. There is a hierarchy like this: EPC <-> shmem <-> disk After data is swapped back in from shmem to EPC, the shmem backing storage needs to be freed. Currently, the backing shmem is not freed. This effectively wastes the shmem while the enclave is running. The memory is recovered when the enclave is destroyed and the backing storage freed. Sort this out by freeing memory with shmem_truncate_range(), as soon as a page is faulted back to the EPC. In addition, free the memory for PCMD pages as soon as all PCMD's in a page have been marked as unused by zeroing its contents.

[PATCH v2 2/2] drm/atomic: Force bridge self-refresh-exit on CRTC switch

by Brian Norris

It's possible to change which CRTC is in use for a given connector/encoder/bridge while we're in self-refresh without fully disabling the connector/encoder/bridge along the way. This can confuse the bridge encoder/bridge, because (a) it needs to track the SR state (trying to perform "active" operations while the panel is still in SR can be Bad(TM)); and (b) it tracks the SR state via the CRTC state (and after the switch, the previous SR state is lost). Thus, we need to either somehow carry the self-refresh state over to the new CRTC, or else force an encoder/bridge self-refresh transition during such a switch. I choose the latter, so we disable the encoder (and exit PSR) before attaching it to the new CRTC (where we can continue to assume a clean (non-self-refresh) state). This fixes PSR issues seen on Rockchip RK3399 systems with drivers/gpu/drm/bridge/analogix/analogix_dp_core.c. Change in v2: - Drop "->enable" condition; this could possibly be "->active" to reflect the intended hardware state, but it also is a little over-specific. We want to make a transition through "disabled" any time we're exiting PSR at the same time as a CRTC switch.

[PATCH] mm: Handle ksize() vs __alloc_size by forgetting size

by Kees Cook

If ksize() is used on an allocation, the compiler cannot make any assumptions about its size any more (as hinted by __alloc_size). Force it to forget. One caller was using a container_of() construction that needed to be worked around.
