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 4.4.31 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 4.4.31 stable release shall be applied: i2c: xgene: Avoid dma_buffer overrun i2c: core: fix NULL pointer dereference under race condition drm/dp/mst: Clear port->pdt when tearing down the i2c adapter h8300: fix syscall restarting libxfs: clean up _calc_dquots_per_chunk mm/list_lru.c: avoid error-path NULL pointer deref mm: memcontrol: do not recurse in direct reclaim KEYS: Fix short sprintf buffer in /proc/keys show function ALSA: usb-audio: Add quirk for Syntek STK1160 ALSA: hda - Merge RIRB_PRE_DELAY into CTX_WORKAROUND caps ALSA: hda - Raise AZX_DCAPS_RIRB_DELAY handling into top drivers ALSA: hda - allow 40 bit DMA mask for NVidia devices ALSA: hda - Adding a new group of pin cfg into ALC295 pin quirk table ALSA: hda - Fix headset mic detection problem for two Dell laptops ANDROID: binder: Add strong ref checks ANDROID: binder: Clear binder and cookie when setting handle in flat binder struct btrfs: fix races on root_log_ctx lists ubifs: Abort readdir upon error ubifs: Fix regression in ubifs_readdir() mei: txe: don't clean an unprocessed interrupt cause. usb: gadget: function: u_ether: don't starve tx request queue USB: serial: fix potential NULL-dereference at probe USB: serial: ftdi_sio: add support for Infineon TriBoard TC2X7 xhci: use default USB_RESUME_TIMEOUT when resuming ports. usb: increase ohci watchdog delay to 275 msec GenWQE: Fix bad page access during abort of resource allocation Fix potential infoleak in older kernels vt: clear selection before resizing hv: do not lose pending heartbeat vmbus packets xhci: add restart quirk for Intel Wildcatpoint PCH tty: limit terminal size to 4M chars USB: serial: cp210x: fix tiocmget error handling dm: free io_barrier after blk_cleanup_queue call KVM: x86: fix wbinvd_dirty_mask use-after-free KVM: MIPS: Make ERET handle ERL before EXL ovl: fsync after copy-up parisc: Ensure consistent state when switching to kernel stack at syscall entry virtio_ring: Make interrupt suppression spec compliant virtio: console: Unlock vqs while freeing buffers dm mirror: fix read error on recovery after default leg failure Input: i8042 - add XMG C504 to keyboard reset table firewire: net: guard against rx buffer overflows firewire: net: fix fragmented datagram_size off-by-one mac80211: discard multicast and 4-addr A-MSDUs scsi: megaraid_sas: Fix data integrity failure for JBOD (passthrough) devices scsi: scsi_debug: Fix memory leak if LBP enabled and module is unloaded scsi: arcmsr: Send SYNCHRONIZE_CACHE command to firmware mmc: dw_mmc-pltfm: fix the potential NULL pointer dereference Revert "drm/radeon: fix DP link training issue with second 4K monitor" drm/radeon/si_dpm: Limit clocks on HD86xx part drm/radeon/si_dpm: workaround for SI kickers drm/radeon: drop register readback in cayman_cp_int_cntl_setup drm/dp/mst: Check peer device type before attempting EDID read perf build: Fix traceevent plugins build race x86/xen: fix upper bound of pmd loop in xen_cleanhighmap() powerpc/ptrace: Fix out of bounds array access warning ARM: 8584/1: floppy: avoid gcc-6 warning mm/cma: silence warnings due to max() usage drm/exynos: fix error handling in exynos_drm_subdrv_open cgroup: avoid false positive gcc-6 warning smc91x: avoid self-comparison warning Disable "frame-address" warning UBI: fastmap: scrub PEB when bitflips are detected in a free PEB EC header pwm: Unexport children before chip removal usb: dwc3: Fix size used in dma_free_coherent() tty: vt, fix bogus division in csi_J kvm: x86: Check memopp before dereference (CVE-2016-8630) ubi: fastmap: Fix add_vol() return value test in ubi_attach_fastmap() HID: usbhid: add ATEN CS962 to list of quirky devices Linux 4.4.31 ** Affects: linux (Ubuntu) Importance: Undecided Status: New ** Affects: linux (Ubuntu Xenial) Importance: Undecided Assignee: Luis Henriques (henrix) Status: In Progress ** Tags: kernel-stable-tracking-bug ** Tags added: kernel-stable-tracking-bug ** Also affects: linux (Ubuntu Xenial) Importance: Undecided Status: New ** Description changed: + SRU Justification - 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.
