[PATCH 1/8] KVM: SVM: extract VMCB accessors to a new file

by Paolo Bonzini

Having inline functions confuses the compilation of asm-offsets.c, which cannot find kvm_cache_regs.h because arch/x86/kvm is not in asm-offset.c's include path. Just extract the functions to a new file. No functional change intended.

Linux 4.14.297

by Greg Kroah-Hartman

I'm announcing the release of the 4.14.297 kernel. All users of the 4.14 kernel series must upgrade.

[PATCH v2 2/2] PM: hibernate: add check of preallocate mem for image size pages

by xiongxin

Added a check on the return value of preallocate_image_highmem(). If memory preallocate is insufficient, S4 cannot be done; I am playing 4K video on a machine with AMD or other graphics card and only 8GiB memory, and the kernel is not configured with CONFIG_HIGHMEM. When doing the S4 test, the analysis found that when the pages get from minimum_image_size() is large enough, The preallocate_image_memory() and preallocate_image_highmem() calls failed to obtain enough memory. Add the judgment that memory preallocate is insufficient; The detailed debugging data is as follows: image_size: 3225923584, totalram_pages: 1968948 in hibernate_reserved_size_init(); in hibernate_preallocate_memory(): code pages = minimum_image_size(saveable) = 717992, at this time(line): count: 2030858 avail_normal: 2053753 highmem: 0 totalreserve_pages: 22895 max_size: 1013336 size: 787579 saveable: 1819905 When the code executes to: pages = preallocate_image_memory(alloc, avail_normal), at that time(line): pages_highmem: 0 avail_normal: 1335761 alloc: 1017522 pages: 1017522 So enter the else branch judged by (pages < alloc), When executed to size = preallocate_image_memory(alloc, avail_normal): alloc = max_size - size = 225757; size = preallocate_image_memory(alloc, avail_normal) = 168671, That is, preallocate_image_memory() does not apply for all alloc memory pages, because highmem is not enabled, and size_highmem will return 0 here, so there is a memory page that has not been preallocated, so I think a judgment needs to be added here. But what I can't understand is that although pages are not preallocated enough, "pages -= free_unnecessary_pages()" in the code below can also discard some pages that have been preallocated, so I am not sure whether it is appropriate to add a judgment here.

[PATCH v2 1/2] PM: hibernate: fix spelling mistake for annotation

by xiongxin

The actual calculation formula in the code below is: max_size = (count - (size + PAGES_FOR_IO)) / 2 - 2 * DIV_ROUND_UP(reserved_size, PAGE_SIZE); But function comments are written differently, the comment is wrong? By the way, what exactly do the "/ 2" and "2 *" mean?

[PATCH] tee: add overflow check in tee_ioctl_shm_register()

by Jens Wiklander

commit 573ae4f13f630d6660008f1974c0a8a29c30e18a upstream. With special lengths supplied by user space, tee_shm_register() has an integer overflow when calculating the number of pages covered by a supplied user space memory region. This may cause pin_user_pages_fast() to do a NULL pointer dereference. Fix this by adding an an explicit call to access_ok() in tee_ioctl_shm_register() to catch an invalid user space address early.

From: Xiubo Li <xiubli(a)redhat.com> When decoding the snaps fails it maybe leaving the 'first_realm' and 'realm' pointing to the same snaprealm memory.
