openvswitch: get related ct labels from its master if it is not confirmed

[ Upstream commit a23ac973f67f37e77b3c634e8b1ad5b0164fcc1f ]

Ilya found a failure in running check-kernel tests with at_groups=144
(144: conntrack - FTP SNAT orig tuple) in OVS repo. After his further
investigation, the root cause is that the labels sent to userspace
for related ct are incorrect.

The labels for unconfirmed related ct should use its master's labels.
However, the changes made in commit 8c8b73320805 ("openvswitch: set
IPS_CONFIRMED in tmpl status only when commit is set in conntrack")
led to getting labels from this related ct.

So fix it in ovs_ct_get_labels() by changing to copy labels from its
master ct if it is a unconfirmed related ct. Note that there is no
fix needed for ct->mark, as it was already copied from its master
ct for related ct in init_conntrack().

net: openvswitch: fix unwanted error log on timeout policy probing

[ Upstream commit 4539f91f2a801c0c028c252bffae56030cfb2cae ]

On startup, ovs-vswitchd probes different datapath features including
support for timeout policies. While probing, it tries to execute
certain operations with OVS_PACKET_ATTR_PROBE or OVS_FLOW_ATTR_PROBE
attributes set. These attributes tell the openvswitch module to not
log any errors when they occur as it is expected that some of the
probes will fail.

For some reason, setting the timeout policy ignores the PROBE attribute
and logs a failure anyway. This is causing the following kernel log
on each re-start of ovs-vswitchd:

kernel: Failed to associated timeout policy `ovs_test_tp'

Fix that by using the same logging macro that all other messages are
using. The message will still be printed at info level when needed
and will be rate limited, but with a net rate limiter instead of
generic printk one.

The nf_ct_set_timeout() itself will still print some info messages,
but at least this change makes logging in openvswitch module more
consistent.

net/sched: act_ct: Always fill offloading tuple iifidx

[ Upstream commit 9bc64bd0cd765f696fcd40fc98909b1f7c73b2ba ]

Referenced commit doesn't always set iifidx when offloading the flow to
hardware. Fix the following cases:

- nf_conn_act_ct_ext_fill() is called before extension is created with
nf_conn_act_ct_ext_add() in tcf_ct_act(). This can cause rule offload with
unspecified iifidx when connection is offloaded after only single
original-direction packet has been processed by tc data path. Always fill
the new nf_conn_act_ct_ext instance after creating it in
nf_conn_act_ct_ext_add().

- Offloading of unidirectional UDP NEW connections is now supported, but ct
flow iifidx field is not updated when connection is promoted to
bidirectional which can result reply-direction iifidx to be zero when
refreshing the connection. Fill in the extension and update flow iifidx
before calling flow_offload_refresh().

====================
genetlink: provide struct genl_info to dumps

One of the biggest (which is not to say only) annoyances with genetlink
handling today is that doit and dumpit need some of the same information,
but it is passed to them in completely different structs.

The implementations commonly end up writing a _fill() method which
populates a message and have to pass at least 6 parameters. 3 of which
are extracted manually from request info.

After a lot of umming and ahing I decided to populate struct genl_info
for dumps, without trying to factor out only the common parts.
This makes the adoption easiest.

In the future we may add a new version of dump which takes
struct genl_info *info as the second argument, instead of
struct netlink_callback *cb. For now developers have to call
genl_info_dump(cb) to get the info.

Typical genetlink families no longer get exposed to netlink protocol
internals like pid and seq numbers.

- correct the condition in ethtool code (patch 10)
v2: https://lore.kernel.org/all/20230810233845.2318049-1-kuba@kernel.org/

Adrian Moreno says:

====================
openvswitch: add drop reasons

There is currently a gap in drop visibility in the openvswitch module.
This series tries to improve this by adding a new drop reason subsystem
for OVS.

Apart from adding a new drop reasson subsystem and some common drop
reasons, this series takes Eric's preliminary work [1] on adding an
explicit drop action and integrates it into the same subsystem.

A limitation of this series is that it does not report upcall errors.
The reason is that there could be many sources of upcall drops and the
most common one, which is the netlink buffer overflow, cannot be
reported via kfree_skb() because the skb is freed in the netlink layer
(see [2]). Therefore, using a reason for the rare events and not the
common one would be even more misleading. I'd propose we add (in a
follow up patch) a tracepoint to better report upcall errors.

Merge branch 'net-handle-the-exp-removal-problem-with-ovs-upcall-properly'

Xin Long says:

====================
net: handle the exp removal problem with ovs upcall properly

With the OVS upcall, the original ct in the skb will be dropped, and when
the skb comes back from userspace it has to create a new ct again through
nf_conntrack_in() in either OVS __ovs_ct_lookup() or TC tcf_ct_act().

However, the new ct will not be able to have the exp as the original ct
has taken it away from the hash table in nf_ct_find_expectation(). This
will cause some flow never to be matched, like:

'ip,ct_state=-trk,in_port=1 actions=ct(zone=1)'
'ip,ct_state=+trk+new+rel,in_port=1 actions=ct(commit,zone=1)'
'ip,ct_state=+trk+new+rel,in_port=1 actions=ct(commit,zone=2),normal'

if the 2nd flow triggers the OVS upcall, the 3rd flow will never get
matched.

OVS conntrack works around this by adding its own exp lookup function to
not remove the exp from the hash table and saving the exp and its master
info to the flow keys instead of create a real ct. But this way doesn't
work for TC act_ct.

The patch 1/3 allows nf_ct_find_expectation() not to remove the exp from
the hash table if tmpl is set with IPS_CONFIRMED when doing lookup. This
allows both OVS conntrack and TC act_ct to have a simple and clear fix
for this problem in the patch 2/3 and 3/3.

- Significantly reduce the search time for module symbols by
livepatch and BPF.

- Enable cpumasks to be used as kptrs, which is useful for tracing
programs tracking which tasks end up running on which CPUs in
different time intervals.

- Add support for BPF trampoline on s390x and riscv64.

- Add capability to export the XDP features supported by the NIC.

- Add __bpf_kfunc tag for marking kernel functions as kfuncs.

- Add cgroup.memory=nobpf kernel parameter option to disable BPF
memory accounting for container environments.

Netfilter:

- Remove the CLUSTERIP target. It has been marked as obsolete for
years, and we still have WARN splats wrt races of the out-of-band
/proc interface installed by this target.

- Add 'destroy' commands to nf_tables. They are identical to the
existing 'delete' commands, but do not return an error if the
referenced object (set, chain, rule...) did not exist.

Driver API:

- Improve cpumask_local_spread() locality to help NICs set the right
IRQ affinity on AMD platforms.

- Separate C22 and C45 MDIO bus transactions more clearly.

- Introduce new DCB table to control DSCP rewrite on egress.

- Support configuration of Physical Layer Collision Avoidance (PLCA)
Reconciliation Sublayer (RS) (802.3cg-2019). Modern version of
shared medium Ethernet.

- Support for MAC Merge layer (IEEE 802.3-2018 clause 99). Allowing
preemption of low priority frames by high priority frames.

- Add support for controlling MACSec offload using netlink SET.

- Rework devlink instance refcounts to allow registration and
de-registration under the instance lock. Split the code into
multiple files, drop some of the unnecessarily granular locks and
factor out common parts of netlink operation handling.

- Add TX frame aggregation parameters (for USB drivers).

- Add a new attr TCA_EXT_WARN_MSG to report TC (offload) warning
messages with notifications for debug.

- Allow offloading of UDP NEW connections via act_ct.

- Add support for per action HW stats in TC.

- Support hardware miss to TC action (continue processing in SW from
a specific point in the action chain).

- Warn if old Wireless Extension user space interface is used with
modern cfg80211/mac80211 drivers. Do not support Wireless
Extensions for Wi-Fi 7 devices at all. Everyone should switch to
using nl80211 interface instead.

- Improve the CAN bit timing configuration. Use extack to return
error messages directly to user space, update the SJW handling,
including the definition of a new default value that will benefit
CAN-FD controllers, by increasing their oscillator tolerance.
