Some of the code paths calculating flow hash for IPv6 use flowlabel member
of struct flowi6 which, despite its name, encodes both flow label and
traffic class. If traffic class changes within a TCP connection (as e.g.
ssh does), ECMP route can switch between path. It's also inconsistent with
other code paths where ip6_flowlabel() (returning only flow label) is used
to feed the key.
Use only flow label everywhere, including one place where hash key is set
using ip6_flowinfo().
Fixes: 51ebd3181572 ("ipv6: add support of equal cost multipath (ECMP)")
Fixes: f70ea018da06 ("net: Add functions to get skb->hash based on flow structures")

This adds support for Flexible PPS output (which is equivalent
to per_out output of PTP subsystem).
Tested using an oscilloscope and the following commands:
1) Start PTP4L:
# ptp4l -A -4 -H -m -i eth0 &
2) Set Flexible PPS frequency:
# echo <idx> <ts> <tns> <ps> <pns> > /sys/class/ptp/ptpX/period
Where, ts/tns is start time and ps/pns is period time, and ptpX is ptp
of eth0.

selftests: forwarding: mirror_vlan: Fixlets
This patchset includes two small fixes for the tests that were
introduced in commit 1bb58d2d3cbe ("Merge branch
'Mirroring-tests-involving-VLAN'").
In patch #1, a "tc action trap" is uninstalled after the suite runs,
instead of being installed again.
In patch #2, a test in suite is renamed to differentiate it from another
test of the same name.

Add regression tests for PF_PACKET transmission using packet_snd.
The TPACKET ring interface has tests for transmission and reception.
This is an initial stab at the same for the send call based interface.
Packets are sent over loopback, then read twice. The entire packet is
read from another packet socket and compared. The packet is also
verified to arrive at a UDP socket for protocol conformance.
The test sends a packet over loopback, testing the following options
(not the full cross-product):
- SOCK_DGRAM
- SOCK_RAW
- vlan tag
- qdisc bypass
- bind() and sendto()
- virtio_net_hdr
- csum offload (NOT actual csum feature, ignored on loopback)
- gso
Besides these basic functionality tests, the test runs from a set
of bounds checks, positive and negative. Running over loopback, which
has dev->min_header_len, it cannot generate variable length hhlen.

If there is a significant amount of chains list search is too slow, so
add an rhlist table for this.
This speeds up ruleset loading: for every new rule we have to check if
the name already exists in current generation.
We need to be able to cope with duplicate chain names in case a transaction
drops the nfnl mutex (for request_module) and the abort of this old
transaction is still pending.
The list is kept -- we need a way to iterate chains even if hash resize is
in progress without missing an entry.

This features which allows you to limit the maximum number of
connections per arbitrary key. The connlimit expression is stateful,
therefore it can be used from meters to dynamically populate a set, this
provides a mapping to the iptables' connlimit match. This patch also
comes that allows you define static connlimit policies.
This extension depends on the nf_conncount infrastructure.

Pull SCSI fix from James Bottomley:
"Eve of merge window fix: The original code was so bogus as to be
casting the wrong generic device to an rport and proceeding to take
actions based on the bogus values it found.
Fortunately it seems the location that is dereferenced always exists,
so the code hasn't oopsed yet, but it certainly annoys the memory
checkers"

Before this patch, cloned expressions are released via ->destroy. This
is a problem for the new connlimit expression since the ->destroy path
drop a reference on the conntrack modules and it unregisters hooks. The
new ->destroy_clone provides context that this expression is being
released from the packet path, so it is mirroring ->clone(), where
neither module reference is dropped nor hooks need to be unregistered -
because this done from the control plane path from the ->init() path.

Use garbage collector to schedule removal of elements based of feedback
from expression that this element comes with. Therefore, the garbage
collector is not guided by timeout expirations in this new mode.
The new connlimit expression sets on the NFT_EXPR_GC flag to enable this
behaviour, the dynset expression needs to explicitly enable the garbage
collector via set->ops->gc_init call.

nft_set_elem_destroy() can be called from call_rcu context. Annotate
netns and table in set object so we can populate the context object.
Moreover, pass context object to nf_tables_set_elem_destroy() from the
commit phase, since it is already available from there.

The extracted functions will likely be usefull to implement tproxy
support in nf_tables.
Extrancted functions:
- nf_tproxy_sk_is_transparent
- nf_tproxy_laddr4
- nf_tproxy_handle_time_wait4
- nf_tproxy_get_sock_v4
- nf_tproxy_laddr6
- nf_tproxy_handle_time_wait6
- nf_tproxy_get_sock_v6
(nf_)tproxy_handle_time_wait6 also needed some refactor as its current
implementation was xtables-specific.

There is a function in include/net/netfilter/nf_socket.h to decide if a
socket has IP(V6)_TRANSPARENT socket option set or not. However this
does the same as inet_sk_transparent() in include/net/tcp.h
include/net/tcp.h:1733
/* This helper checks if socket has IP_TRANSPARENT set */
static inline bool inet_sk_transparent(const struct sock *sk)
{
switch (sk->sk_state) {
case TCP_TIME_WAIT:
return inet_twsk(sk)->tw_transparent;
case TCP_NEW_SYN_RECV:
return inet_rsk(inet_reqsk(sk))->no_srccheck;
}
return inet_sk(sk)->transparent;
}
tproxy_sk_is_transparent has also been refactored to use this function
instead of reimplementing it.

will fix it more fully outside -rc.
