mlxsw: Support multiple RIF MAC prefixes
Currently, mlxsw enforces that all the netdevs used as router interfaces
(RIFs) have the same MAC prefix (e.g., same 38 MSBs in Spectrum-1).
Otherwise, an error is returned to user space with extack. This patchset
relaxes the limitation through the use of RIF MAC profiles.
A RIF MAC profile is a hardware entity that represents a particular MAC
prefix which multiple RIFs can reference. Therefore, the number of
possible MAC prefixes is no longer one, but the number of profiles
supported by the device.
The ability to change the MAC of a particular netdev is useful, for
example, for users who use the netdev to connect to an upstream provider
that performs MAC filtering. Currently, such users are either forced to
negotiate with the provider or change the MAC address of all other
netdevs so that they share the same prefix.
Patchset overview:
Patches #1-#3 are preparations.
Patch #4 adds actual support for RIF MAC profiles.
Patch #5 exposes RIF MAC profiles as a devlink resource, so that user
space has visibility into the maximum number of profiles and current
occupancy. Useful for debugging and testing (next 3 patches).
Patches #6-#8 add both scale and functional tests.
Patch #9 removes tests that validated the previous limitation. It is now
covered by patch #6 for devices that support a single profile.

Currently, mlxsw enforces that all the router interfaces (RIFs) have the
same MAC prefix.
Relax this limitation by using RIF MAC profiles. Each profile is
associated with a particular MAC prefix and multiple RIFs can use the
same profile. Therefore, the number of possible MAC prefixes is no
longer one, but the number of profiles supported by the device.
Store the profiles in an IDR and reference count them according to the
number of RIFs using them.
Associate a RIF with a profile when the RIF is created and remove the
association when the RIF is deleted.
Change the association following 'NETDEV_CHANGEADDR' events, except when
only one RIF is using the profile. In which case, change the MAC prefix
of the profile itself instead of associating the RIF with a new profile.

The next patch will set the MAC profile of a router interface (RIF) as
part of its configure() callback. The operation can fail in case the
maximum number of profiles was exceeded.
Add extack to mlxsw_sp_rif_ops::configure() in order to communicate such
failures to user space.
In addition, the MAC profile of a RIF can change following a
'NETDEV_CHANGEADDR' notification. Propagate extack to
mlxsw_sp_router_port_change_event() so that failures could be
communicated in this path as well.
No functional changes intended.

vrf: rework interaction with netfilter/conntrack
V2:
- fix 'plain integer as null pointer' warning
- reword commit message in patch 2 to clarify loss of 'ct set untracked'
This patch series aims to solve the to-be-reverted change 09e856d54b
("vrf: Reset skb conntrack connection on VRF rcv") in a different way.
Rather than have skbs pass through conntrack and nat hooks twice, suppress
conntrack invocation if the conntrack/nat hook is called from the vrf driver.
First patch deals with 'incoming connection' case:
1. suppress NAT transformations
2. skip conntrack confirmation
NAT and conntrack confirmation is done when ip/ipv6 stack calls
the postrouting hook.
Second patch deals with local packets:
in vrf driver, mark the skbs as 'untracked', so conntrack output
hook ignores them. This skips all nat hooks as well.
Afterwards, remove the untracked state again so the second
round will pick them up.
One alternative to the chosen implementation would be to add a 'caller
id' field to 'struct nf_hook_state' and then use that, these patches
use the more straightforward check of VRF flag on the state->out device.
The two patches apply to both net and net-next, i am targeting -next
because I think that since snat did not work correctly for so long that
we can take the longer route. If you disagree, apply to net at your
discretion.
The patches apply both with 09e856d54b reverted or still
in-place, but only with the revert in place ingress conntrack settings
(zone, notrack etc) start working again.
I've already submitted selftests for vrf+nfqueue and conntrack+vrf.

The VRF driver invokes netfilter for output+postrouting hooks so that users
can create rules that check for 'oif $vrf' rather than lower device name.
This is a problem when NAT rules are configured.
To avoid any conntrack involvement in round 1, tag skbs as 'untracked'
to prevent conntrack from picking them up.
This gets cleared before the packet gets handed to the ip stack so
conntrack will be active on the second iteration.
One remaining issue is that a rule like
output ... oif $vrfname notrack
won't propagate to the second round because we can't tell
'notrack set via ruleset' and 'notrack set by vrf driver' apart.
However, this isn't a regression: the 'notrack' removal happens
instead of unconditional nf_reset_ct().
I'd also like to avoid leaking more vrf specific conditionals into the
netfilter infra.
For ingress, conntrack has already been done before the packet makes it
to the vrf driver, with this patch egress does connection tracking with
lower/physical device as well.

The VRF driver invokes netfilter for output+postrouting hooks so that users
can create rules that check for 'oif $vrf' rather than lower device name.
Afterwards, ip stack calls those hooks again.
This is a problem when conntrack is used with IP masquerading.
masquerading has an internal check that re-validates the output
interface to account for route changes.
This check will trigger in the vrf case.
If the -j MASQUERADE rule matched on the first iteration, then round 2
finds state->out->ifindex != nat->masq_index: the latter is the vrf
index, but out->ifindex is the lower device.
The packet gets dropped and the conntrack entry is invalidated.
This change makes conntrack postrouting skip the nat hooks.
Also skip confirmation. This allows the second round
(postrouting invocation from ipv4/ipv6) to create nat bindings.
This also prevents the second round from seeing packets that had their
source address changed by the nat hook.

v1: Implement a more general statement as recommended by Eric Dumazet. The
sequence number will be advanced, so this check will fix the FIN case and
other cases.
A customer reported sockets stuck in the CLOSING state. A Vmcore revealed that
the write_queue was not empty as determined by tcp_write_queue_empty() but the
sk_buff containing the FIN flag had been freed and the socket was zombied in
that state. Corresponding pcaps show no FIN from the Linux kernel on the wire.
Some instrumentation was added to the kernel and it was found that there is a
timing window where tcp_sendmsg() can run after tcp_send_fin().
tcp_sendmsg() will hit an error, for example:
1269 ▹ if (sk->sk_err || (sk->sk_shutdown & SEND_SHUTDOWN))↩
1270 ▹ ▹ goto do_error;↩
tcp_remove_empty_skb() will then free the FIN sk_buff as "skb->len == 0". The
TCP socket is now wedged in the FIN-WAIT-1 state because the FIN is never sent.
If the other side sends a FIN packet the socket will transition to CLOSING and
remain that way until the system is rebooted.
Fix this by checking for the FIN flag in the sk_buff and don't free it if that
is the case. Testing confirmed that fixed the issue.
