In commit 47b7e7f82802, this bit was removed at the same time the
RT6_LOOKUP_F_IFACE flag was removed. However, it is needed when
link-local addresses are used, which is a very common case: when
packets are routed, neighbor solicitations are done using link-local
addresses. For example, the following neighbor solicitation is not
matched by "-m rpfilter":
IP6 fe80::5254:33ff:fe00:1 > ff02::1:ff00:3: ICMP6, neighbor
solicitation, who has 2001:db8::5254:33ff:fe00:3, length 32
Commit 47b7e7f82802 doesn't quite explain why we shouldn't use
RT6_LOOKUP_F_IFACE in the rpfilter case. I suppose the interface check
later in the function would make it redundant. However, the remaining
of the routing code is using RT6_LOOKUP_F_IFACE when there is no
source address (which matches rpfilter's case with a non-unicast
destination, like with neighbor solicitation).

This reverts commit f92b40a8b2645
("netfilter: core: only allow one nat hook per hook point"), this
limitation is no longer needed. The nat core now invokes these
functions and makes sure that hook evaluation stops after a mapping is
created and a null binding is created otherwise.

Currently the packet rewrite and instantiation of nat NULL bindings
happens from the protocol specific nat backend.
Invocation occurs either via ip(6)table_nat or the nf_tables nat chain type.
Invocation looks like this (simplified):
NF_HOOK()
|
`---iptable_nat
|
`---> nf_nat_l3proto_ipv4 -> nf_nat_packet
|
new packet? pass skb though iptables nat chain
|
`---> iptable_nat: ipt_do_table
In nft case, this looks the same (nft_chain_nat_ipv4 instead of
iptable_nat).
This is a problem for two reasons:
1. Can't use iptables nat and nf_tables nat at the same time,
as the first user adds a nat binding (nf_nat_l3proto_ipv4 adds a
NULL binding if do_table() did not find a matching nat rule so we
can detect post-nat tuple collisions).
2. If you use e.g. nft_masq, snat, redir, etc. uses must also register
an empty base chain so that the nat core gets called fro NF_HOOK()
to do the reverse translation, which is neither obvious nor user
friendly.
After this change, the base hook gets registered not from iptable_nat or
nftables nat hooks, but from the l3 nat core.
iptables/nft nat base hooks get registered with the nat core instead:
NF_HOOK()
|
`---> nf_nat_l3proto_ipv4 -> nf_nat_packet
|
new packet? pass skb through iptables/nftables nat chains
|
+-> iptables_nat: ipt_do_table
+-> nft nat chain x
`-> nft nat chain y
The nat core deals with null bindings and reverse translation.
When no mapping exists, it calls the registered nat lookup hooks until
one creates a new mapping.
If both iptables and nftables nat hooks exist, the first matching
one is used (i.e., higher priority wins).
Also, nft users do not need to create empty nat hooks anymore,
nat core always registers the base hooks that take care of reverse/reply
translation.

This adds the infrastructure to register nat hooks with the nat core
instead of the netfilter core.
nat hooks are used to configure nat bindings. Such hooks are registered
from ip(6)table_nat or by the nftables core when a nat chain is added.
After next patch, nat hooks will be registered with nf_nat instead of
netfilter core. This allows to use many nat lookup functions at the
same time while doing the real packet rewrite (nat transformation) in
one place.
This change doesn't convert the intended users yet to ease review.

This will allow the nat core to reuse the nf_hook infrastructure
to maintain nat lookup functions.
The raw versions don't assume a particular hook location, the
functions get added/deleted from the hook blob that is passed to the
functions.

The ip(6)tables nat table is currently receiving skbs from the netfilter

The bpf syscall and selftests conflicts were trivial
overlapping changes.
The r8169 change involved moving the added mdelay from 'net' into a
different function.
A TLS close bug fix overlapped with the splitting of the TLS state

When application fails to pass flags in netlink TLV when replacing
existing skbmod action, the kernel will leak refcnt:
$ tc actions get action skbmod index 1
total acts 0
action order 0: skbmod pipe set smac 00:11:22:33:44:55
index 1 ref 1 bind 0
For example, at this point a buggy application replaces the action with
index 1 with new smac 00:aa:22:33:44:55, it fails because of zero flags,
however refcnt gets bumped:
$ tc actions get actions skbmod index 1
total acts 0
action order 0: skbmod pipe set smac 00:11:22:33:44:55
index 1 ref 2 bind 0
$

David Howells says:
====================
rxrpc: Fixes
Here are three fixes for AF_RXRPC and two tracepoints that were useful for
finding them:
(1) Fix missing start of expect-Rx-by timeout on initial packet
transmission so that calls will time out if the peer doesn't respond.
(2) Fix error reception on AF_INET6 sockets by using the correct family of
sockopts on the UDP transport socket.
(3) Fix setting the minimum security level on kernel calls so that they
can be encrypted.
(4) Add a tracepoint to log ICMP/ICMP6 and other error reports from the
transport socket.
(5) Add a tracepoint to log UDP sendmsg failure so that we can find out if
transmission failure occurred on the UDP socket.

The caller calls action's ->init() and passes pointer to "struct tc_action *a",
which later may be initialized to point at the existing action, otherwise
"struct tc_action *a" is still invalid, and therefore dereferencing it is an
error as happens in tcf_idr_release, where refcnt is decremented.
So in case of missing flags tcf_idr_release must be called only for
existing actions.

linux-4.16 got support for softirq based hrtimers.
TCP can switch its pacing hrtimer to this variant, since this
avoids going through a tasklet and some atomic operations.
pacing timer logic looks like other (jiffies based) tcp timers.
v2: use hrtimer_try_to_cancel() in tcp_clear_xmit_timers()
to correctly release reference on socket if needed.

Add support for PHYLINK within the DSA subsystem in order to support more
complex devices such as pluggable (SFP) and non-pluggable (SFF) modules, 10G
PHYs, and traditional PHYs. Using PHYLINK allows us to drop some amount of
complexity we had while probing fixed and non-fixed PHYs using Device Tree.
Because PHYLINK separates the Ethernet MAC/port configuration into different
stages, we let switch drivers implement those, and for now, we maintain
functionality by calling dsa_slave_adjust_link() during
phylink_mac_link_{up,down} which provides semantically equivalent steps.
Drivers willing to take advantage of PHYLINK should implement the phylink_mac_*
operations that DSA wraps.
We cannot quite remove the adjust_link() callback just yet, because a number of
drivers rely on that for configuring their "CPU" and "DSA" ports, this is done
dsa_port_setup_phy_of() and dsa_port_fixed_link_register_of() still.
Drivers that utilize fixed links for user-facing ports (e.g: bcm_sf2) will need
to implement phylink_mac_ops from now on to preserve functionality, since PHYLINK
*does not* create a phy_device instance for fixed links.

Since we use PHYLIB to manage the per-port link indication, this will

In preparation for adding support for PHYLINK within DSA, define a number of
operations that we will need and that switch drivers can start implementing.
Proper integration with PHYLINK will follow in subsequent patches.
We start selecting PHYLINK (which implies PHYLIB) in net/dsa/Kconfig
such that drivers can be guaranteed that this dependency is properly
taken care of and can start referencing PHYLINK helper functions without
requiring stubs or anything.

Fix more memory leaks in ip_cmsg_send() callers. Part of them were fixed
earlier in 919483096bfe.
* udp_sendmsg one was there since the beginning when linux sources were
first added to git;
* ping_v4_sendmsg one was copy/pasted in c319b4d76b9e.
Whenever return happens in udp_sendmsg() or ping_v4_sendmsg() IP options
have to be freed if they were allocated previously.
Add label so that future callers (if any) can use it instead of kfree()
before return that is easy to forget.

AF_RXRPC tries to turn on IP_RECVERR and IP_MTU_DISCOVER on the UDP socket
it just opened for communications with the outside world, regardless of the
type of socket. Unfortunately, this doesn't work with an AF_INET6 socket.
Fix this by turning on IPV6_RECVERR and IPV6_MTU_DISCOVER instead if the
socket is of the AF_INET6 family.
Without this, kAFS server and address rotation doesn't work correctly
because the algorithm doesn't detect received network errors.

The expect_rx_by call timeout is supposed to be set when a call is started
to indicate that we need to receive a packet by that point. This is
currently put back every time we receive a packet, but it isn't started
when we first send a packet. Without this, the call may wait forever if
the server doesn't deign to reply.
Fix this by setting the timeout upon a successful UDP sendmsg call for the
first DATA packet. The timeout is initiated only for initial transmission
and not for subsequent retries as we don't want the retry mechanism to
extend the timeout indefinitely.

In Commit 1f45f78f8e51 ("sctp: allow GSO frags to access the chunk too"),
it held the chunk in sctp_ulpevent_make_rcvmsg to access it safely later
in recvmsg. However, it also added sctp_chunk_put in fail_mark err path,
which is only triggered before holding the chunk.
syzbot reported a use-after-free crash happened on this err path, where
it shouldn't call sctp_chunk_put.
This patch simply removes this call.

This version has some suggestions by Eric Dumazet:
- Use a local variable for the mark in IPv6 instead of ctl_sk to avoid SMP
races.
- Use the more elegant "IP4_REPLY_MARK(net, skb->mark) ?: sk->sk_mark"
statement.
- Factorize code as sk_fullsock() check is not necessary.
Aidan McGurn from Openwave Mobility systems reported the following bug:
"Marked routing is broken on customer deployment. Its effects are large
increase in Uplink retransmissions caused by the client never receiving
the final ACK to their FINACK - this ACK misses the mark and routes out
of the incorrect route."
Currently marks are added to sk_buffs for replies when the "fwmark_reflect"
sysctl is enabled. But not for TW sockets that had sk->sk_mark set via
setsockopt(SO_MARK..).
Fix this in IPv4/v6 by adding tw->tw_mark for TIME_WAIT sockets. Copy the the
original sk->sk_mark in __inet_twsk_hashdance() to the new tw->tw_mark location.
Then progate this so that the skb gets sent with the correct mark. Do the same
for resets. Give the "fwmark_reflect" sysctl precedence over sk->sk_mark so that
netfilter rules are still honored.

In commit be47e41d77fb ("tipc: fix use-after-free in tipc_nametbl_stop")
we fixed a problem caused by premature release of service range items.
That fix is correct, and solved the problem. However, it doesn't address
the root of the problem, which is that we don't lookup the tipc_service
-> service_range -> publication items in the correct hierarchical
order.
In this commit we try to make this right, and as a side effect obtain
some code simplification.

No changes in refcount semantics -- key init is false; replace
static_key_enable with static_branch_enable
static_key_slow_inc|dec with static_branch_inc|dec
static_key_false with static_branch_unlikely
Added a '_key' suffix to udp and udpv6 encap_needed, for better
self documentation.
