2021-10-26mlxsw: spectrum_router: Add RIF MAC profiles supportDanielle Ratson2-47/+272
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.

2021-10-26mlxsw: spectrum_router: Propagate extack furtherDanielle Ratson1-8/+15
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.

2021-10-26vrf: run conntrack only in context of lower/physdev for locally generated packetsFlorian Westphal1-4/+24
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.

2021-10-26netfilter: conntrack: skip confirmation and nat hooks in postrouting for vrfFlorian Westphal2-1/+27
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. Signed-off-by: Florian Westphal <fw@strlen.de> Signed-off-by: David S.

2021-10-26tcp: don't free a FIN sk_buff in tcp_remove_empty_skb()Jon Maxwell1-1/+1
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.

2021-10-25usbb: catc: use correct API for MAC addressesOliver Neukum1-5/+17
Commit 406f42fa0d3c ("net-next: When a bond have a massive amount of VLANs...") introduced a rbtree for faster Ethernet address look up. To maintain netdev->dev_addr in this tree we need to make all the writes to it got through appropriate helpers. In the case of catc we need a new temporary buffer to conform to the rules for DMA coherency. That in turn necessitates a reworking of error handling in probe().

2021-10-25gve: Add a jumbo-frame device option.Shailend Chand2-4/+68
A widely deployed driver has a bug that will cause the driver not to load when a max_mtu > 2048 is present in the device descriptor. To avoid this bug while still enabling jumbo frames, we present a lower max_mtu in the device descriptor and pass the actual max_mtu in a separate device option. The driver supports 2 different queue formats. To enable features on one queue format, but not the other, a supported_features mask was added to the device options in the device descriptor.

2021-10-25gve: Implement packet continuation for RX.David Awogbemila9-126/+292
This enables the driver to receive RX packets spread across multiple buffers: For a given multi-fragment packet the "packet continuation" bit is set on all descriptors except the last one. These descriptors' payloads are combined into a single SKB before the SKB is handed to the networking stack. This change adds a "packet buffer size" notion for RX queues. The CreateRxQueue AdminQueue command sent to the device now includes the packet_buffer_size. We opt for a packet_buffer_size of PAGE_SIZE / 2 to give the driver the opportunity to flip pages where we can instead of copying.

2021-10-25gve: Add RX context.David Awogbemila2-37/+44
This refactor moves the skb_head and skb_tail fields into a new gve_rx_ctx struct. This new struct will contain information about the current packet being processed. This is in preparation for multi-descriptor RX packets.

2021-10-25selftests: mlxsw: Reduce test run timeIdo Schimmel2-18/+20
Instead of iterating over all the available trap policers, only perform the tests with three policers: The first, the last and the one in the middle of the range. On a Spectrum-3 system, this reduces the run time from almost an hour to a few minutes.

2021-10-25selftests: mlxsw: Use permanent neighbours instead of reachable onesIdo Schimmel1-11/+11
The nexthop objects tests configure dummy reachable neighbours so that the nexthops will have a MAC address and be programmed to the device. Since these are dummy reachable neighbours, they can be transitioned by the kernel to a failed state if they are around for too long. This can happen, for example, if the "TIMEOUT" variable is configured with a too high value. Make the tests more robust by configuring the neighbours as permanent, so that the tests do not depend on the configured timeout value.

2021-10-25selftests: mlxsw: Add helpers for skipping selftestsPetr Machata8-24/+81
A number of mlxsw-specific selftests currently detect whether they are run on a compatible machine, and bail out silently when not. These tests are however done in a somewhat impenetrable manner by directly comparing PCI IDs against a blacklist or a whitelist, and bailing out silently if the machine is not compatible. Instead, add a helper, mlxsw_only_on_spectrum(), which allows specifying the supported machines in a human-readable manner. If the current machine is incompatible, the helper emits a SKIP message and returns an error code, based on which the caller can gracefully bail out in a suitable way. This allows a more readable conditions such as: mlxsw_only_on_spectrum 2+ || return Convert all existing open-coded guards to the new helper. Also add two new guards to do_mark_test() and do_drop_test(), which are supported only on Spectrum-2+, but the corresponding check was not there.
