According to Guillaume Nault RT_TOS should never be used for IPv6.
Quote:
RT_TOS() is an old macro used to interprete IPv4 TOS as described in
the obsolete RFC 1349. It's conceptually wrong to use it even in IPv4
code, although, given the current state of the code, most of the
existing calls have no consequence.
But using RT_TOS() in IPv6 code is always a bug: IPv6 never had a "TOS"
field to be interpreted the RFC 1349 way. There's no historical
compatibility to worry about.

When resolving the decap route device for a tunnel decap rule,
the result may be an OVS internal port device.
Prior to adding the support for internal port offload, such case
would result in using the uplink as the default decap route device
which allowed devices that can't support internal port offload
to offload this decap rule.
This behavior got broken by adding the internal port offload which
will fail in case the device can't support internal port offload.
To restore the old behavior, use the uplink device as the decap
route as before when internal port offload is not supported.

Mask the ECN bits before calling mlx5e_route_lookup_ipv4_get(). The
tunnel key might have the last ECN bit set. This interferes with the
route lookup process as ip_route_output_key_hash() interpretes this bit
specially (to restrict the route scope).
Found by code inspection, compile tested only.

There is a use case that the local and remote VTEPs are in the same
host. Currently, the out ifindex is not specified when looking up the
decap route for offloads. So in this case, a local route is returned
and the route dev is lo.
Actual tunnel interface can be created with a parameter "dev" [1],
which specifies the physical device to use for tunnel endpoint
communication. Pass this parameter to driver when looking up decap
route for offloads. So that a unicast route will be returned.

When performing route device lookup for decap action, support
the case of ovs internal port as the lookup result.
In such case, an internal port struct is mapped and attached
to the flow attributes so that the source port matching of the
rule will match on the internal port's metadata value.

When pefroming encap action, a route lookup is performed
to find the routing device the packet should be forwarded
to after the encapsulation. This is the device that has the
local tunnel ip address.
This change adds support to offload an encap rule where the
route device ends up being an ovs internal port.
In such case, the driver will add a HW rule that will encapsulate
the packet with the tunnel header and will overwrite the vport
metadata in reg_c0 to the internal port metadata value.
Finally, the packet will be forwarded to the root table to be
processed again with the indication that it came from an internal
port.

Both multipath and bonding events are changing the HW LAG state
independently.
Handling one of the features events while the other is already
enabled can cause unwanted behavior, for example handling
bonding event while multipath enabled will disable the lag and
cause multipath to stop working.
Fix it by ignoring bonding event while in multipath and ignoring FIB
events while in bonding mode.

Adding new reformat context type (INSERT_HEADER) requires adding two new
parameters to reformat context - reformat_param_0 and reformat_param_1.
As defined by HW spec, these parameters have different meaning for
different reformat context type.
The first parameter (reformat_param_0) is not new to HW spec, but it
wasn't used by any of the supported reformats. The second parameter
(reformat_param_1) is new to the HW spec - it was added to allow
supporting INSERT_HEADER.
For NSERT_HEADER, reformat_param_0 indicates the header used to
reference the location of the inserted header, and reformat_param_1
indicates the offset of the inserted header from the reference point
defined by reformat_param_0.

flow_attr->ip_version has the matching that should be done inner/outer.
When working with chains, decapsulation is done on chain0 and next chain
match on outer header which is the original inner which could be ipv4.
So in tunnel route resolution we cannot use that to know which ip version
we are at so save tun_ip_version when parsing the tunnel match and use
that.

Following patch in series implement routing update event which requires
ability to modify rule match_to_reg modify header actions dynamically
during rule lifetime. In order to accommodate such behavior, refactor and
extend TC infrastructure in following ways:
- Modify mod_hdr infrastructure to preserve its parse attribute for whole
rule lifetime, instead of deallocating it after rule creation.
- Extend match_to_reg infrastructure with new function
mlx5e_tc_match_to_reg_set_and_get_id() that returns mod_hdr action id that
can be used afterwards to update the action, and
mlx5e_tc_match_to_reg_mod_hdr_change() that can modify existing actions by
its id.
- Extend tun API with new functions mlx5e_tc_tun_update_header_ipv{4|6}()
that are used to updated existing encap entry tunnel header.

Following patches in series implements route update which can cause encap
entries to migrate between routing devices. Consecutively, their parent
nhe's need to be also transferable between devices instead of having neigh
device as a part of their immutable key. Move neigh device from struct
mlx5_neigh to struct mlx5e_neigh_hash_entry and check that nhe and neigh
devices are the same in workqueue neigh update handler.
Save neigh net_device that can change dynamically in dedicated nhe->dev
field. With FIB event handler that is implemented in following patches
changing nhe->dev, NETEVENT_DELAY_PROBE_TIME_UPDATE handler can
concurrently access the nhe entry when traversing neigh list under rcu read
lock. Processing stale values in that handler doesn't change the handler
logic, so just wrap all accesses to the dev pointer in {WRITE|READ}_ONCE()
helpers.

Refactor tun routing helpers to use dedicated struct
mlx5e_tc_tun_route_attr instead of multiple output arguments. This
simplifies the callers (no need to keep track of bunch of output param

manually release some of the output parameters that require it.
Simplify code by unifying error handling at the end of the function and

In functions mlx5e_route_lookup_ipv{4|6}() route_dev can be arbitrary net
device and not necessary mlx5 eswitch port representor. As such, in order
to ensure that route_dev is not destroyed concurrent the code needs either
explicitly take reference to the device before releasing reference to
rtable instance or ensure that caller holds rtnl lock. First approach is
chosen as a fix since rtnl lock dependency was intentionally removed from
mlx5 TC layer.
To prevent unprotected usage of route_dev in encap code take a reference to
the device before releasing rt. Don't save direct pointer to the device in
mlx5_encap_entry structure and use ifindex instead. Modify users of
route_dev pointer to properly obtain the net device instance from its
ifindex.

MPLS over UDP is supported by adding a rule on a representor net device
which does tunnel_key set, push mpls and forward to a baredup device. At
the hardware level we use a packet_reformat_context object to do the
encapsulation of the packet.
The resulting packet looks as follows (left side transmitted first):
outer L2 | outer IP | UDP | MPLS | inner L3 and data |
Example usage:
tc filter add dev $rep0 protocol ip prio 1 root flower skip_sw \
action tunnel_key set src_ip 8.8.8.21 dst_ip 8.8.8.24 id 555 \
dst_port 6635 tos 4 ttl 6 csum action mpls push protocol 0x8847 \
label 555 tc 3 action mirred egress redirect dev bareudp0
This is how the filter is shown with tc filter show:
tc filter show dev enp59s0f0_0 ingress
filter protocol ip pref 1 flower chain 0
filter protocol ip pref 1 flower chain 0 handle 0x1
eth_type ipv4

Currently, tunnel parsing is split between en_tc and tc_tun. The next
patch will replace the tunnel fields matching with a register match,
and will not need this parsing.
Move the tunnel parsing logic to tc_tun as a pre-step for skipping
it in the next patch.

ipv6_stub uses the ip6_dst_lookup function to allow other modules to
perform IPv6 lookups. However, this function skips the XFRM layer
entirely.
All users of ipv6_stub->ip6_dst_lookup use ip_route_output_flow (via the
ip_route_output_key and ip_route_output helpers) for their IPv4 lookups,
which calls xfrm_lookup_route(). This patch fixes this inconsistent
behavior by switching the stub to ip6_dst_lookup_flow, which also calls
xfrm_lookup_route().
This requires some changes in all the callers, as these two functions
take different arguments and have different return types.

Improve mlx5e_route_lookup_ipv6 function structure by avoiding #ifdef then
return -EOPNOTSUPP in the middle of the function code.
To do so, we stub out mlx5e_tc_tun_create_header_ipv6 which is the only
caller of this helper function to avoid calling it altogether
when ipv6 is compiled out, which should also cleanup some compiler
warnings of unused variables.

Add HW offloading support for flows with Geneve encap/decap.
Notes about decap flows with Geneve TLV Options:
- Support offloading of 32-bit options data only
- At any given time, only one combination of class/type parameters
can be offloaded, but the same class/type combination can have
many different flows offloaded with different 32-bit option data
- Options with value of 0 can't be offloaded

Rearrange tc tunnel code so that it would be easy to add future tunnels:
- Define tc tunnel object with the fields and callbacks that any
tunnel must implement.
- Define tc UDP tunnel object for UDP tunnels, such as VXLAN
- Move each tunnel code (GRE, VXLAN) to its own separate file
- Rewrite tc tunnel implementation in a general way - using only
the objects and their callbacks.

In mlx5e encap entry structure, IP tunnel info data structure is copied
by value. This approach worked till now, but it breaks when there are
encapsulation options, such as in case of Geneve.
These options are stored in the structure that is allocated adjacent to
the IP tunnel info struct, and not pointed at by any field in that struct.
Therefore, when copying the struct by value, we loose the address of the
original struct and can't get to the encapsulation options.
Fix the problem by storing the pointer to the tunnel info data instead.
