Public bug reported:
SRU Justification
Impact:
The upstream process for stable tree updates is quite similar
in scope to the Ubuntu SRU process, e.g., each patch has to
demonstrably fix a bug, and each patch is vetted by upstream
by originating either directly from a mainline/stable Linux tree or
a minimally backported form of that patch. The v4.4.61 upstream stable
patch set is now available. It should be included in the Ubuntu
kernel as well.
git://git.kernel.org/
TEST CASE: TBD
The following patches from the v4.4.61 stable release shall be
applied:
drm/vmwgfx: Type-check lookups of fence objects
drm/vmwgfx: NULL pointer dereference in vmw_surface_define_ioctl()
drm/vmwgfx: avoid calling vzalloc with a 0 size in vmw_get_cap_3d_ioctl()
drm/ttm, drm/vmwgfx: Relax permission checking when opening surfaces
drm/vmwgfx: Remove getparam error message
drm/vmwgfx: fix integer overflow in vmw_surface_define_ioctl()
sysfs: be careful of error returns from ops->show()
staging: android: ashmem: lseek failed due to no FMODE_LSEEK.
arm/arm64: KVM: Take mmap_sem in stage2_unmap_vm
arm/arm64: KVM: Take mmap_sem in kvm_arch_prepare_memory_region
iio: bmg160: reset chip when probing
Reset TreeId to zero on SMB2 TREE_CONNECT
ptrace: fix PTRACE_LISTEN race corrupting task->state
ring-buffer: Fix return value check in test_ringbuffer()
metag/usercopy: Drop unused macros
metag/usercopy: Fix alignment error checking
metag/usercopy: Add early abort to copy_to_user
metag/usercopy: Zero rest of buffer from copy_from_user
metag/usercopy: Set flags before ADDZ
metag/usercopy: Fix src fixup in from user rapf loops
metag/usercopy: Add missing fixups
powerpc/mm: Add missing global TLB invalidate if cxl is active
powerpc: Don't try to fix up misaligned load-with-reservation instructions
nios2: reserve boot memory for device tree
s390/decompressor: fix initrd corruption caused by bss clear
s390/uaccess: get_user() should zero on failure (again)
MIPS: Force o32 fp64 support on 32bit MIPS64r6 kernels
MIPS: ralink: Fix typos in rt3883 pinctrl
MIPS: End spinlocks with .insn
MIPS: Lantiq: fix missing xbar kernel panic
MIPS: Flush wrong invalid FTLB entry for huge page
mm/mempolicy.c: fix error handling in set_mempolicy and mbind.
