iavf: allow changing VLAN state without calling PF

[ Upstream commit ee7d79433d783346430ee32f28c9df44a88b3bb6 ]

iavf: allow changing VLAN state without calling PF

[ Upstream commit ee7d79433d783346430ee32f28c9df44a88b3bb6 ]

First case:
> ip l a l $VF name vlanx type vlan id 100
> ip l d vlanx
> ip l a l $VF name vlanx type vlan id 100

As workqueue can be execute after sometime, there is a window to have
call trace like that:
- iavf_del_vlan
- iavf_add_vlan
- iavf_del_vlans (wq)

It means that our VLAN 100 will change the state from IAVF_VLAN_ACTIVE
to IAVF_VLAN_REMOVE (iavf_del_vlan). After that in iavf_add_vlan state
won't be changed because VLAN 100 is on the filter list. The final
result is that the VLAN 100 filter isn't added in hardware (no
iavf_add_vlans call).

To fix that change the state if the filter wasn't removed yet directly
to active. It is save as IAVF_VLAN_REMOVE means that virtchnl message
wasn't sent yet.

Second case:
> ip l a l $VF name vlanx type vlan id 100
Any type of VF reset ex. change trust
> ip l s $PF vf $VF_NUM trust on
> ip l d vlanx
> ip l a l $VF name vlanx type vlan id 100

In case of reset iavf driver is responsible for readding all filters
that are being used. To do that all VLAN filters state are changed to
IAVF_VLAN_ADD. Here is even longer window for changing VLAN state from
kernel side, as workqueue isn't called immediately. We can have call
trace like that:

- changing to IAVF_VLAN_ADD (after reset)
- iavf_del_vlan (called from kernel ops)
- iavf_del_vlans (wq)

Not exsisitng VLAN filters will be removed from hardware. It isn't a
bug, ice driver will handle it fine. However, we can have call trace
like that:

- changing to IAVF_VLAN_ADD (after reset)
- iavf_del_vlan (called from kernel ops)
- iavf_add_vlan (called from kernel ops)
- iavf_del_vlans (wq)

With fix for previous case we end up with no VLAN filters in hardware.
We have to remove VLAN filters if the state is IAVF_VLAN_ADD and delete
VLAN was called. It is save as IAVF_VLAN_ADD means that virtchnl message
wasn't sent yet.

iavf: Fix iavf_shutdown to call iavf_remove instead iavf_close

[ Upstream commit 7ae42ef308ed0f6250b36f43e4eeb182ebbe6215 ]

Make the flow for pci shutdown be the same to the pci remove.

iavf_shutdown was implementing an incomplete version
of iavf_remove. It misses several calls to the kernel like
iavf_free_misc_irq, iavf_reset_interrupt_capability, iounmap
that might break the system on reboot or hibernation.

Implement the call of iavf_remove directly in iavf_shutdown to
close this gap.

Fixes below error messages (dmesg) during shutdown stress tests -

Reproduction:

1. Create one VF interface:
echo 1 > /sys/class/net/<interface_name>/device/sriov_numvfs

2. Run live dmesg on the host:
dmesg -wH

3. On SUT, script below steps into vf_namespace_assignment.sh

ip netns exec ns$loop ip link set dev $if up
ip netns exec ns$loop ip link set dev $if netns 1
ip netns delete ns$loop

done

4. Run the script for at least 1000 iterations on SUT:

Default is on. If turned off, the filters will be removed from both
PF and iavf list. The removal is irrespective of current filter state.

Steps to reproduce:
-------------------

1. Ensure ntuple is on.

ethtool -K enp8s0 ntuple-filters on

2. Create a filter to receive the traffic into non-default rx-queue like 15
and ensure traffic is flowing into queue into 15.
Now, turn off ntuple. Traffic should not flow to configured queue 15.
It should flow to default RX queue.

iavf: Introduce new state machines for flow director

iavf: Introduce new state machines for flow director

[ Upstream commit 3a0b5a2929fdeda63fc921c2dbed237059acf732 ]

New states introduced:

IAVF_FDIR_FLTR_DIS_REQUEST
IAVF_FDIR_FLTR_DIS_PENDING
IAVF_FDIR_FLTR_INACTIVE

Current FDIR state machines (SM) are not adequate to handle a few
scenarios in the link DOWN/UP event, reset event and ntuple-feature.

For example, when VF link goes DOWN and comes back UP administratively,
the expectation is that previously installed filters should also be
restored. But with current SM, filters are not restored.
So with new SM, during link DOWN filters are marked as INACTIVE in
the iavf list but removed from PF. After link UP, SM will transition
from INACTIVE to ADD_REQUEST to restore the filter.

Similarly, with VF reset, filters will be removed from the PF, but
marked as INACTIVE in the iavf list. Filters will be restored after
reset completion.

Steps to reproduce:
-------------------

1. Create a VF. Here VF is enp8s0.

2. Assign IP addresses to VF and link partner and ping continuously
from remote. Here remote IP is 1.1.1.1.

3. Check default RX Queue of traffic.

ethtool -S enp8s0 | grep -E "rx-[[:digit:]]+\.packets"

4. Add filter - change default RX Queue (to 15 here)

ethtool -U ens8s0 flow-type ip4 src-ip 1.1.1.1 action 15 loc 5

5. Ensure filter gets added and traffic is received on RX queue 15 now.

Link event testing:
-------------------
6. Bring VF link down and up. If traffic flows to configured queue 15,
test is success, otherwise it is a failure.

Reset event testing:
--------------------
7. Reset the VF. If traffic flows to configured queue 15, test is success,
otherwise it is a failure.

iavf: Fix promiscuous mode configuration flow messages

iavf: Fix promiscuous mode configuration flow messages

[ Upstream commit 221465de6bd8090ab61267f019866e8d2dd4ea3d ]

Currently when configuring promiscuous mode on the AVF we detect a
change in the netdev->flags. We use IFF_PROMISC and IFF_ALLMULTI to
determine whether or not we need to request/release promiscuous mode
and/or multicast promiscuous mode. The problem is that the AQ calls for
setting/clearing promiscuous/multicast mode are treated separately. This
leads to a case where we can trigger two promiscuous mode AQ calls in
a row with the incorrect state. To fix this make a few changes.

Use IAVF_FLAG_AQ_CONFIGURE_PROMISC_MODE instead of the previous
IAVF_FLAG_AQ_[REQUEST|RELEASE]_[PROMISC|ALLMULTI] flags.

In iavf_set_rx_mode() detect if there is a change in the
netdev->flags in comparison with adapter->flags and set the
IAVF_FLAG_AQ_CONFIGURE_PROMISC_MODE aq_required bit. Then in
iavf_process_aq_command() only check for IAVF_FLAG_CONFIGURE_PROMISC_MODE
and call iavf_set_promiscuous() if it's set.

In iavf_set_promiscuous() check again to see which (if any) promiscuous
mode bits have changed when comparing the netdev->flags with the
adapter->flags. Use this to set the flags which get sent to the PF
driver.

Add a spinlock that is used for updating current_netdev_promisc_flags
and only allows one promiscuous mode AQ at a time.

[1] Fixes the fact that we will only have one AQ call in the aq_required
queue at any one time.

[2] Streamlines the change in promiscuous mode to only set one AQ
required bit.

[3] This allows us to keep track of the current state of the flags and
also makes it so we can take the most recent netdev->flags promiscuous
mode state.

[4] This fixes the problem where a change in the netdev->flags can cause
IAVF_FLAG_AQ_CONFIGURE_PROMISC_MODE to be set in iavf_set_rx_mode(),
but cleared in iavf_set_promiscuous() before the change is ever made via
AQ call.

In iavf_down, we're skipping the scheduling of certain operations if

request must not be skipped in this case, because iavf_close waits
for the transition to the __IAVF_DOWN state, which happens in
iavf_virtchnl_completion after the queues are released.

Without this fix, "rmmod iavf" takes half a second per interface that's
up and prints the "Device resources not yet released" warning.

aq_required:
adapter->aq_required |= IAVF_FLAG_AQ_ADD_VLAN_FILTER;
or:
adapter->aq_required |= IAVF_FLAG_AQ_DEL_VLAN_FILTER;

This is later processed by the watchdog_task, but it runs periodically
every 2 seconds, so it can be a long time before it processes the request.

In the worst case, the interface is unable to receive traffic for more
than 2 seconds for no objective reason.

Current result:
There is a probability that the mac of VF in guest is inconsistent with
it in host

Expected result:
When passthrough NIC VF to guest, the VF in guest should always get
the same mac as it in host.

Merge tag 'net-next-6.6' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next

Pull networking updates from Paolo Abeni:
"Core:

- Increase size limits for to-be-sent skb frag allocations. This
allows tun, tap devices and packet sockets to better cope with
large writes operations

- Store netdevs in an xarray, to simplify iterating over netdevs

- Refactor nexthop selection for multipath routes

- Improve sched class lifetime handling

- Add backup nexthop ID support for bridge

- Implement drop reasons support in openvswitch

- Several data races annotations and fixes

- Constify the sk parameter of routing functions

- Prepend kernel version to netconsole message

Protocols:

- Implement support for TCP probing the peer being under memory
pressure

- Remove hard coded limitation on IPv6 specific info placement inside
the socket struct

- Get rid of sysctl_tcp_adv_win_scale and use an auto-estimated per
socket scaling factor

- Scaling-up the IPv6 expired route GC via a separated list of
expiring routes

- In-kernel support for the TLS alert protocol

- Better support for UDP reuseport with connected sockets

- Add NEXT-C-SID support for SRv6 End.X behavior, reducing the SR
header size

- Get rid of additional ancillary per MPTCP connection struct socket

- Implement support for BPF-based MPTCP packet schedulers

- Format MPTCP subtests selftests results in TAP

- Several new SMC 2.1 features including unique experimental options,
max connections per lgr negotiation, max links per lgr negotiation

BPF:

- Multi-buffer support in AF_XDP

- Add multi uprobe BPF links for attaching multiple uprobes and usdt
probes, which is significantly faster and saves extra fds

- Implement an fd-based tc BPF attach API (TCX) and BPF link support
on top of it

- Add SO_REUSEPORT support for TC bpf_sk_assign

- Support new instructions from cpu v4 to simplify the generated code
and feature completeness, for x86, arm64, riscv64

- Support defragmenting IPv(4|6) packets in BPF

- Teach verifier actual bounds of bpf_get_smp_processor_id() and fix
perf+libbpf issue related to custom section handling

- Introduce bpf map element count and enable it for all program types

- Add a BPF hook in sys_socket() to change the protocol ID from
IPPROTO_TCP to IPPROTO_MPTCP to cover migration for legacy

- Introduce bpf_me_mcache_free_rcu() and fix OOM under stress

- Add uprobe support for the bpf_get_func_ip helper

- Check skb ownership against full socket

- Support for up to 12 arguments in BPF trampoline

- Extend link_info for kprobe_multi and perf_event links

Netfilter:

- Speed-up process exit by aborting ruleset validation if a fatal
signal is pending

- Allow NLA_POLICY_MASK to be used with BE16/BE32 types

Driver API:

- Page pool optimizations, to improve data locality and cache usage

- Introduce ndo_hwtstamp_get() and ndo_hwtstamp_set() to avoid the
need for raw ioctl() handling in drivers

- Simplify genetlink dump operations (doit/dumpit) providing them the
common information already populated in struct genl_info

- Extend and use the yaml devlink specs to [re]generate the split ops

- Introduce devlink selective dumps, to allow SF filtering SF based
on handle and other attributes

- Add yaml netlink spec for netlink-raw families, allow route, link
and address related queries via the ynl tool

- Remove phylink legacy mode support

- Support offload LED blinking to phy

- Add devlink port function attributes for IPsec
