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 following upstream
stable patches should be included in the Ubuntu kernel:
4.4.222 upstream stable release
from git://git.kernel.org/
The following patches from the 4.4.222 stable release shall be applied:
* ext4: fix special inode number checks in __ext4_iget()
* drm/qxl: qxl_release leak in qxl_hw_surface_alloc()
* ALSA: pcm: oss: Place the plugin buffer overflow checks correctly
* PM: ACPI: Output correct message on target power state
* RDMA/mlx4: Initialize ib_spec on the stack
* vfio/type1: Fix VA->PA translation for PFNMAP VMAs in vaddr_get_pfn()
* ALSA: opti9xx: shut up gcc-10 range warning
* nfs: Fix potential posix_acl refcnt leak in nfs3_set_acl
* dmaengine: dmatest: Fix iteration non-stop logic
* i2c: designware-pci: use IRQF_COND_SUSPEND flag
* perf hists: Fix HISTC_MEM_DCACHELINE width setting
* powerpc/perf: Remove PPMU_HAS_SSLOT flag for Power8
* perf/x86: Fix uninitialized value usage
* exynos4-is: fix a format string bug
* ASoC: wm8960: Fix WM8960_SYSCLK_PLL mode
* ASoC: imx-spdif: Fix crash on suspend
* ipv6: use READ_ONCE() for inet->hdrincl as in ipv4
* selinux: properly handle multiple messages in selinux_netlink_send()
* Linux 4.4.222
