Michal fixes check of scheduling node weight and priority to be done
against desired value, not current value.

Jesse adds setting of all multicast when adding promiscuous mode to
resolve traffic being lost due to filter settings.

syzbot found arm64 builds would crash in sock_recv_mark()
when CONFIG_HARDENED_USERCOPY=y

x86 and powerpc are not detecting the issue because
they define user_access_begin.
This will be handled in a different patch,
because a check_object_size() is missing.

Only data from skb->cb[] can be copied directly to/from user space,
as explained in commit 79a8a642 ("net: Whitelist
the skbuff_head_cache "cb" field")

syzbot report was:

So far changing the period by just setting new period values while
running did not work.

The order as indicated by the publicly available reference manual of the i.MX8MP [1]
indicates a sequence:

 * initiate the programming sequence
 * set the values for PPS period and start time
 * start the pulse train generation.

This is currently not used in dwmac5_flex_pps_config(), which instead does:

 * initiate the programming sequence and immediately start the pulse train generation
 * set the values for PPS period and start time

This caused the period values written not to take effect until the FlexPPS output was
disabled and re-enabled again.

This patch fix the order and allows the period to be set immediately.

There was a problem reported to us where the addition of a VF with an IPv6
address ending with a particular sequence would cause the parent device on
the PF to no longer be able to respond to neighbor discovery packets.

In this case, we had an ovs-bridge device living on top of a VLAN, which
was on top of a PF, and it would not be able to talk anymore (the neighbor
entry would expire and couldn't be restored).

The root cause of the issue is that if the PF is asked to be in IFF_PROMISC
mode (promiscuous mode) and it had an ipv6 address that needed the
33:33:ff:00:00:04 multicast address to work, then when the VF was added
with the need for the same multicast address, the VF would steal all the
traffic destined for that address.

The ice driver didn't auto-subscribe a request of IFF_PROMISC to the
"multicast replication from other port's traffic" meaning that it won't get
for instance, packets with an exact destination in the VF, as above.

The VF's IPv6 address, which adds a "perfect filter" for 33:33:ff:00:00:04,
results in no packets for that multicast address making it to the PF (which
is in promisc but NOT "multicast replication").

The fix is to enable "multicast promiscuous" whenever the driver is asked
to enable IFF_PROMISC, and make sure to disable it when appropriate.

In bnxt_reserve_rings(), there is logic to check that the number of TX
rings reserved is enough to cover all the mqprio TCs, but it fails to
account for the TX XDP rings.  So the check will always fail if there
are mqprio TCs and TX XDP rings.  As a result, the driver always fails
to initialize after the XDP program is attached and the device will be
brought down.  A subsequent ifconfig up will also fail because the
number of TX rings is set to an inconsistent number.  Fix the check to
properly account for TX XDP rings.  If the check fails, set the number
of TX rings back to a consistent number after calling netdev_reset_tc().

When converting net_device_stats to rtnl_link_stats64 sign extension
is triggered on ILP32 machines as 6c1c5097 changed the previous
"ulong -> u64" conversion to "long -> u64" by accessing the
net_device_stats fields through a (signed) atomic_long_t.

This causes for example the received bytes counter to jump to 16EiB after
having received 2^31 bytes. Casting the atomic value to "unsigned long"
beforehand converting it into u64 avoids this.

Christoph Paasch reported that commit b5fc2923 ("inet6: Remove
inet6_destroy_sock() in sk->sk_prot->destroy().") started triggering
WARN_ON_ONCE(sk->sk_forward_alloc) in sk_stream_kill_queues().  [0 - 2]
Also, we can reproduce it by a program in [3].

In the commit, we delay freeing ipv6_pinfo.pktoptions from sk->destroy()
to sk->sk_destruct(), so sk->sk_forward_alloc is no longer zero in
inet_csk_destroy_sock().

The same check has been in inet_sock_destruct() from at least v2.6,
we can just remove the WARN_ON_ONCE().  However, among the users of
sk_stream_kill_queues(), only CAIF is not calling inet_sock_destruct().
Thus, we add the same WARN_ON_ONCE() to caif_sock_destructor().

We add a new helper which clones a skb and sets its owner only

Note that we move skb_set_owner_r() forward in (dccp|tcp)_v6_do_rcv()

ipv6_opt_accepted() in the crossed SYN-ACK or self-connect() cases.

In TI's AM62x/AM64x SoCs, successful teardown of RX DMA Channel raises an
interrupt. The process of servicing this interrupt involves flushing all
pending RX DMA descriptors and clearing the teardown completion marker
(TDCM). The am65_cpsw_nuss_rx_packets() function invoked from the RX
NAPI callback services the interrupt. Thus, it is necessary to wait for
this handler to run, drain all packets and clear TDCM, before calling
napi_disable() in am65_cpsw_nuss_common_stop() function post channel
teardown. If napi_disable() executes before ensuring that TDCM is
cleared, the TDCM remains set when the interfaces are down, resulting in
an interrupt storm when the interfaces are brought up again.

Since the interrupt raised to indicate the RX DMA Channel teardown is
specific to the AM62x and AM64x SoCs, add a quirk for it.

Commit b3973bb4 ("vmxnet3: set correct hash type based on

rssType field is populated for eop descriptor. This can lead
to incorrectly reporting of hashType for packets which use
multiple rx descriptors. Multiple rx descriptors are used
for Jumbo frame or LRO packets, which can hit this issue.

This patch moves the RSS codeblock under eop descritor.

ipv6: Fix socket connection with DSCP fib-rules.

The "flowlabel" field of struct flowi6 is used to store both the actual
flow label and the DS Field (or Traffic Class). However the .connect
handlers of datagram and TCP sockets don't set the DS Field part when
doing their route lookup. This breaks fib-rules that match on DSCP.

Add the fib_rule6_send and fib_rule4_send tests to verify that DSCP
values are properly taken into account when UDP or TCP sockets try to
connect().

Tests are done with nettest, which needs a new option to specify
the DS Field value of the socket being tested. This new option is
named '-Q', in reference to the similar option used by ping.

Take into account the IPV6_TCLASS socket option (DSCP) in

So it's clear that something in the PTP RX trapping logic went wrong.

Looking a bit at the code, I can see that there are 4 typos, which
populate "ipv4" VCAP IS2 key filter fields for IPv6 keys.

VCAP IS2 keys of type OCELOT_VCAP_KEY_IPV4 and OCELOT_VCAP_KEY_IPV6 are
handled by is2_entry_set(). OCELOT_VCAP_KEY_IPV4 looks at
&filter->key.ipv4, and OCELOT_VCAP_KEY_IPV6 at &filter->key.ipv6.
Simply put, when we populate the wrong key field, &filter->key.ipv6
fields "proto.mask" and "proto.value" remain all zeroes (or "don't care").
So is2_entry_set() will enter the "else" of this "if" condition:

	if (msk == 0xff && (val == IPPROTO_TCP || val == IPPROTO_UDP))

and proceed to ignore the "proto" field. The resulting rule will match
on all IPv6 traffic, trapping it to the CPU.

This is the reason why the local_termination.sh selftest sees it,
because control traps are stronger than the PGID_MCIPV6 used for
flooding (from the forwarding data path).

But the problem is in fact much deeper. We trap all IPv6 traffic to the
CPU, but if we're bridged, we set skb->offload_fwd_mark = 1, so software
forwarding will not take place and IPv6 traffic will never reach its
destination.

The fix is simple - correct the typos.

I was intentionally inaccurate in the commit message about the breakage
occurring when any PTP timestamping is enabled. In fact it only happens
when L4 timestamping is requested (HWTSTAMP_FILTER_PTP_V2_EVENT or
HWTSTAMP_FILTER_PTP_V2_L4_EVENT). But ptp4l requests a larger RX
timestamping filter than it needs for "-2": HWTSTAMP_FILTER_PTP_V2_EVENT.
I wanted people skimming through git logs to not think that the bug
doesn't affect them because they only use ptp4l in L2 mode.
