When using the PF_KEY interface, SHA-256 hashes are hardcoded to
use 96-bit truncation. This is a violation of RFC4868, which
specifies 128-bit truncation, but will not be fixed upstream due
to backwards compatibility concerns and because the PF_KEY
interface is deprecated in favour of netlink XFRM (which allows
the app to specify an arbitrary truncation length).
Change the hardcoded truncation length from 96 to 128 so that
PF_KEY apps such as racoon will work with standards-compliant VPN
servers.

To prevent protential risk of memory leak caused by closing socket with
out untag it from qtaguid module, the qtaguid module now do not hold any
socket file reference count. Instead, it will increase the sk_refcnt of
the sk struct to prevent a reuse of the socket pointer. And when a socket
is released. It will delete the tag if the socket is previously tagged so
no more resources is held by xt_qtaguid moudle. A flag is added to the untag
process to prevent possible kernel crash caused by fail to delete
corresponding socket_tag_entry list.

commit 4617f564c0 upstream.
When calling a dm ioctl that doesn't process any data
(IOCTL_FLAGS_NO_PARAMS), the contents of the data field in struct
dm_ioctl are left initialized. Current code is incorrectly extending
the size of data copied back to user, causing the contents of kernel
stack to be leaked to user. Fix by only copying contents before data
and allow the functions processing the ioctl to override.

commit dc434e056f upstream.
The setup/remove_state/instance() functions in the hotplug core code are
serialized against concurrent CPU hotplug, but unfortunately not serialized
against themself.
As a consequence a concurrent invocation of these function results in
corruption of the callback machinery because two instances try to invoke
callbacks on remote cpus at the same time. This results in missing callback
invocations and initiator threads waiting forever on the completion.
The obvious solution to replace get_cpu_online() with cpu_hotplug_begin()
is not possible because at least one callsite calls into these functions
from a get_online_cpu() locked region.
Extend the protection scope of the cpuhp_state_mutex from solely protecting
the state arrays to cover the callback invocation machinery as well.
