2a2403ca3a tipc: increment the tmp aead refcnt before attaching it
Li Shuang found a NULL pointer dereference crash in her testing:

  [] BUG: unable to handle kernel NULL pointer dereference at 0000000000000020
  [] RIP: 0010:tipc_crypto_rcv_complete+0xc8/0x7e0 [tipc]
  [] Call Trace:
  []  <IRQ>

  []  ipv6_rcv+0x395/0x510
  []  __netif_receive_skb_core+0x5fc/0xc40

This is caused by NULL returned by tipc_aead_get(), and then crashed when
dereferencing it later in tipc_crypto_rcv_complete(). This might happen
when tipc_crypto_rcv_complete() is called by two threads at the same time:
the tmp attached by tipc_crypto_key_attach() in one thread may be released
by the one attached by that in the other thread.

This patch is to fix it by incrementing the tmp's refcnt before attaching
it instead of calling tipc_aead_get() after attaching it.

4b4b84468a mld: change lockdep annotation for ip6_sf_socklist and ipv6_mc_socklist
struct ip6_sf_socklist and ipv6_mc_socklist are per-socket MLD data.
These data are protected by rtnl lock, socket lock, and RCU.
So, when these are used, it verifies whether rtnl lock is acquired or not.

ip6_mc_msfget() is called by do_ipv6_getsockopt().
But caller doesn't acquire rtnl lock.
So, when these data are used in the ip6_mc_msfget() lockdep warns about it.
But accessing these is actually safe because socket lock was acquired by
do_ipv6_getsockopt().

So, it changes lockdep annotation from rtnl lock to socket lock.
(rtnl_dereference -> sock_dereference)

Locking graph for mld data is like below:

When writing mld data:
do_ipv6_setsockopt()
    rtnl_lock
    lock_sock
    (mld functions)
        idev->mc_lock(if per-interface mld data is modified)

When reading mld data:
do_ipv6_getsockopt()
    lock_sock
    ip6_mc_msfget()

Splat looks like:
=============================

f20a46c304 tipc: fix unique bearer names sanity check
When enabling a bearer by name, we don't sanity check its name with
higher slot in bearer list. This may have the effect that the name
of an already enabled bearer bypasses the check.

To fix the above issue, we just perform an extra checking with all
existing bearers.

6bf24dc0cc net:tipc: Fix a double free in tipc_sk_mcast_rcv
In the if(skb_peek(arrvq) == skb) branch, it calls __skb_dequeue(arrvq) to get
the skb by skb = skb_peek(arrvq). Then __skb_dequeue() unlinks the skb from arrvq
and returns the skb which equals to skb_peek(arrvq). After __skb_dequeue(arrvq)
finished, the skb is freed by kfree_skb(__skb_dequeue(arrvq)) in the first time.

Unfortunately, the same skb is freed in the second time by kfree_skb(skb) after
the branch completed.

My patch removes kfree_skb() in the if(skb_peek(arrvq) == skb) branch, because
this skb will be freed by kfree_skb(skb) finally.

998d3907f4 tipc: re-organize members of struct publication
In a future commit we will introduce more members to struct publication.
In order to keep this structure comprehensible we now group some of
its current fields into the sub-structures where they really belong,
- A struct tipc_service_range for the functional address the publication
  is representing.
- A struct tipc_socket_addr for the socket bound to that service range.

We also rename the stack variable 'publ' to just 'p' in a few places.
This is just as easy to understand in the given context, and keeps the
number of wrapped code lines to a minimum.

There are no functional changes in this commit.

0398ba9e5a net: tipc: prevent possible null deref of link
`tipc_node_apply_property` does a null check on a `tipc_link_entry`
pointer but also accesses the same pointer out of the null check block.

This triggers a warning on Coverity Static Analyzer because we're
implying that `e->link` can BE null.

Move "Update MTU for node link entry" line into if block to make sure
that we're not in a state that `e->link` is null.
