The function mlxsw_sp_nexthop_rif_update() walks the list of nexthops associated with a RIF, and updates the corresponding entries in the switch. It is used in particular when a tunnel underlay netdevice moves to a different VRF, and all the nexthops are migrated over to a new RIF. The problem is that each nexthop holds a reference to its RIF, and that is not updated. So after the old RIF is gone, further activity on these nexthops (such as downing the underlay netdevice) dereferences a dangling pointer. Fix the issue by updating rif of impacted nexthops before calling mlxsw_sp_nexthop_rif_update().

Some tunnels that are offloadable on their own can nonetheless be demoted to slow path if their local address is in conflict with that of another tunnel. When a route is formed for such a tunnel, mlxsw_sp_nexthop_ipip_init() fails to find the corresponding IPIP entry, and that triggers a FIB abort. Resolve the problem by not assuming that a tunnel for which mlxsw_sp_ipip_ops.can_offload() holds also automatically has an IPIP entry.

The mlxsw driver currently doesn't offload GRE tunnels if they have the same local address and use the same underlay VRF. When such a situation arises, the tunnels in conflict are demoted to slow path. However, the current code only verifies this condition on tunnel creation and tunnel change, not when a tunnel is moved to a different VRF. When the tunnel has no bound device, underlay and overlay are the same. Thus moving a tunnel moves the underlay as well, and that can cause local address conflict. So modify mlxsw_sp_netdevice_ipip_ol_vrf_event() to check if there are any conflicting tunnels, and demote them if yes.

Do not try to create a port if during driver initialization it was assigned a negative module number, which is invalid. This avoids the following error during unsplit: [ 941.012478] mlxsw_spectrum 0000:01:00.0: Port 43: Failed to map module The error is harmless and caused by the fact that a local port is already mapped to module 0.

As the page free path makes no distinction between cache hot and cold pages, there is no real useful ordering of pages in the free list that allocation requests can take advantage of. Juding from the users of __GFP_COLD, it is likely that a number of them are the result of copying other sites instead of actually measuring the impact. Remove the __GFP_COLD parameter which simplifies a number of paths in the page allocator. This is potentially controversial but bear in mind that the size of the per-cpu pagelists versus modern cache sizes means that the whole per-cpu list can often fit in the L3 cache. Hence, there is only a potential benefit for microbenchmarks that alloc/free pages in a tight loop. It's even worse when THP is taken into account which has little or no chance of getting a cache-hot page as the per-cpu list is bypassed and the zeroing of multiple pages will thrash the cache anyway. The truncate microbenchmarks are not shown as this patch affects the allocation path and not the free path. A page fault microbenchmark was tested but it showed no sigificant difference which is not surprising given that the __GFP_COLD branches are a miniscule percentage of the fault path.

When the VLAN tag is present in the packet buffer (i.e VLAN stripping disabled, QinQ) the driver will currently report CHECKSUM_UNNECESSARY. Instead of using CHECKSUM_COMPLETE offload for packets with first ethertype of IPv4/6, use it for packets with last ethertype of IPv4/6 to cover the former cases as well. The checksum field present in the CQE is calculated from the IP header until the end of the packet. When the first ethertype is different than IPv4/6 (for ex. 802.1Q VLAN) a checksum of the VLAN header/s should be added. The small header/s checksum calculation will allow us to use CHECKSUM_COMPLETE instead of CHECKSUM_UNNECESSARY.
