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 v4.4.56 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 v4.4.56 stable release shall be applied: netlink: remove mmapped netlink support UBUNTU: [Config] CONFIG_NETLINK_MMAP disappeared vxlan: correctly validate VXLAN ID against VXLAN_N_VID vti6: return GRE_KEY for vti6 ipv4: mask tos for input route l2tp: avoid use-after-free caused by l2tp_ip_backlog_recv net: don't call strlen() on the user buffer in packet_bind_spkt() net: net_enable_timestamp() can be called from irq contexts dccp: Unlock sock before calling sk_free() tcp: fix various issues for sockets morphing to listen state net: fix socket refcounting in skb_complete_wifi_ack() net: fix socket refcounting in skb_complete_tx_timestamp() dccp: fix use-after-free in dccp_feat_activate_values vrf: Fix use-after-free in vrf_xmit uapi: fix linux/packet_diag.h userspace compilation error act_connmark: avoid crashing on malformed nlattrs with null parms mpls: Send route delete notifications when router module is unloaded ipv6: make ECMP route replacement less greedy ipv6: avoid write to a possibly cloned skb bridge: drop netfilter fake rtable unconditionally dccp/tcp: fix routing redirect race dccp: fix memory leak during tear-down of unsuccessful connection request net sched actions: decrement module reference count after table flush. fscrypt: fix renaming and linking special files fscrypto: lock inode while setting encryption policy x86/kasan: Fix boot with KASAN=y and PROFILE_ANNOTATED_BRANCHES=y x86/perf: Fix CR4.PCE propagation to use active_mm instead of mm futex: Fix potential use-after-free in FUTEX_REQUEUE_PI futex: Add missing error handling to FUTEX_REQUEUE_PI Linux 4.4.56 ** Affects: linux (Ubuntu) Importance: Undecided Status: New ** Affects: linux (Ubuntu Xenial) Importance: Undecided Status: New ** 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.
