2022-05-07Merge branch 'Be explicit with XFRM offload direction'Steffen Klassert
Leon Romanovsky says: ==================== I may admit that the title of this series is not the best one as it contains straightforward cleanups and code that converts flags to something less confusing. This series follows removal of FPGA IPsec code from the mlx5 driver and based on net-next commit 4950b6990e3b ("Merge branch 'ocelot-vcap-cleanups'"). As such, first two patches delete code that was used by mlx5 FPGA code but isn't needed anymore. Third patch is simple struct rename. Rest of the patches separate user's provided flags variable from driver's usage. This allows us to created more simple in-kernel interface, that supports type checking without blending different properties into one variable. It is achieved by converting flags to specific bitfield variables with clear, meaningful names. Such change allows us more clear addition of new input flags needed to mark IPsec offload type. The followup code uses this extensively: https://git.kernel.org/pub/scm/linux/kernel/git/leon/linux-rdma.git/log/?h=xfrm-next ==================== Signed-off-by: Steffen Klassert <steffen.klassert@secunet.com>
2022-05-06Merge branch 'simplify-migration-of-host-filtered-addresses-in-felix-driver'Jakub Kicinski
Vladimir Oltean says: ==================== Simplify migration of host filtered addresses in Felix driver The purpose of this patch set is to remove the functions dsa_port_walk_fdbs() and dsa_port_walk_mdbs() from the DSA core, which were introduced when the Felix driver gained support for unicast filtering on standalone ports. They get called when changing the tagging protocol back and forth between "ocelot" and "ocelot-8021q". I did not realize we could get away without having them. The patch set was regression-tested using the local_termination.sh selftest using both tagging protocols. ==================== Link: https://lore.kernel.org/r/20220505162213.307684-1-vladimir.oltean@nxp.com Signed-off-by: Jakub Kicinski <kuba@kernel.org>

2022-05-06net: dsa: felix: perform MDB migration based on ocelot->multicast listVladimir Oltean
The felix driver is the only user of dsa_port_walk_mdbs(), and there isn't even a good reason for it, considering that the host MDB entries are already saved by the ocelot switch lib in the ocelot->multicast list. Rewrite the multicast entry migration procedure around the ocelot->multicast list so we can delete dsa_port_walk_mdbs().

2022-05-06net: dsa: felix: stop migrating FDBs back and forth on tag proto changeVladimir Oltean
I just realized we don't need to migrate the host-filtered FDB entries when the tagging protocol changes from "ocelot" to "ocelot-8021q". Host-filtered addresses are learned towards the PGID_CPU "multicast" port group, reserved by software, which contains BIT(ocelot->num_phys_ports). That is the "special" port entry in the analyzer block for the CPU port module. In "ocelot" mode, the CPU port module's packets are redirected to the NPI port. In "ocelot-8021q" mode, felix_8021q_cpu_port_init() does something funny anyway, and changes PGID_CPU to stop pointing at the CPU port module and start pointing at the physical port where the DSA master is attached. The fact that we can alter the destination of packets learned towards PGID_CPU without altering the MAC table entries themselves means that it is pointless to walk through the FDB entries, forget that they were learned towards PGID_CPU, and re-learn them towards the "unicast" PGID associated with the physical port connected to the DSA master. We can let the PGID_CPU value change simply alter the destination of the host-filtered unicast packets in one fell swoop.

2022-05-06net: dsa: felix: use PGID_CPU for FDB entry migration on NPI portVladimir Oltean
ocelot_fdb_add() redirects FDB entries installed on the NPI port towards the special reserved PGID_CPU used for host-filtered addresses. PGID_CPU contains BIT(ocelot->num_phys_ports) in the destination port mask, which is code name for the CPU port module. Whereas felix_migrate_fdbs_to_*_port() uses the ocelot->num_phys_ports PGID directly, and it appears that this works too. Even if this PGID is set to zero, apparently its number is special and packets still reach the CPU port module. Nonetheless, in the end, these addresses end up in the same place regardless of whether they go through an extra indirection layer or not. Use PGID_CPU across to have more uniformity.

2022-05-06ice: clear stale Tx queue settings before configuringAnatolii Gerasymenko
The iAVF driver uses 3 virtchnl op codes to communicate with the PF regarding the VF Tx queues: * VIRTCHNL_OP_CONFIG_VSI_QUEUES configures the hardware and firmware logic for the Tx queues * VIRTCHNL_OP_ENABLE_QUEUES configures the queue interrupts * VIRTCHNL_OP_DISABLE_QUEUES disables the queue interrupts and Tx rings. There is a bug in the iAVF driver due to the race condition between VF reset request and shutdown being executed in parallel. This leads to a break in logic and VIRTCHNL_OP_DISABLE_QUEUES is not being sent. If this occurs, the PF driver never cleans up the Tx queues. This results in leaving behind stale Tx queue settings in the hardware and firmware. The most obvious outcome is that upon the next VIRTCHNL_OP_CONFIG_VSI_QUEUES, the PF will fail to program the Tx scheduler node due to a lack of space. We need to protect ICE driver against such situation. To fix this, make sure we clear existing stale settings out when handling VIRTCHNL_OP_CONFIG_VSI_QUEUES. This ensures we remove the previous settings. Calling ice_vf_vsi_dis_single_txq should be safe as it will do nothing if the queue is not configured. The function already handles the case when the Tx queue is not currently configured and exits with a 0 return in that case.

2022-05-06ice: Fix race during aux device (un)pluggingIvan Vecera
Function ice_plug_aux_dev() assigns pf->adev field too early prior aux device initialization and on other side ice_unplug_aux_dev() starts aux device deinit and at the end assigns NULL to pf->adev. This is wrong because pf->adev should always be non-NULL only when aux device is fully initialized and ready. This wrong order causes a crash when ice_send_event_to_aux() call occurs because that function depends on non-NULL value of pf->adev and does not assume that aux device is half-initialized or half-destroyed. After order correction the race window is tiny but it is still there, as Leon mentioned and manipulation with pf->adev needs to be protected by mutex. Fix (un-)plugging functions so pf->adev field is set after aux device init and prior aux device destroy and protect pf->adev assignment by new mutex. This mutex is also held during ice_send_event_to_aux() call to ensure that aux device is valid during that call. Note that device lock used ice_send_event_to_aux() needs to be kept to avoid race with aux drv unload. Reproducer: cycle=1 while :;do echo "#### Cycle: $cycle" ip link set ens7f0 mtu 9000 ip link add bond0 type bond mode 1 miimon 100 ip link set bond0 up ifenslave bond0 ens7f0 ip link set bond0 mtu 9000 ethtool -L ens7f0 combined 1 ip link del bond0 ip link set ens7f0 mtu 1500 sleep 1 let cycle++ done In short when the device is added/removed to/from bond the aux device is unplugged/plugged. When MTU of the device is changed an event is sent to aux device asynchronously. This can race with (un)plugging operation and because pf->adev is set too early (plug) or too late (unplug) the function ice_send_event_to_aux() can touch uninitialized or destroyed fields. In the case of crash below pf->adev->dev.mutex.

2022-05-06KVM: VMX: Exit to userspace if vCPU has injected exception and invalid stateSean Christopherson
Exit to userspace with an emulation error if KVM encounters an injected exception with invalid guest state, in addition to the existing check of bailing if there's a pending exception (KVM doesn't support emulating exceptions except when emulating real mode via vm86). In theory, KVM should never get to such a situation as KVM is supposed to exit to userspace before injecting an exception with invalid guest state. But in practice, userspace can intervene and manually inject an exception and/or stuff registers to force invalid guest state while a previously injected exception is awaiting reinjection.

2022-05-06Revert "ice: Hide bus-info in ethtool for PRs in switchdev mode"Marcin Szycik
This reverts commit bfaaba99e680bf82bf2cbf69866c3f37434ff766. Commit bfaaba99e680 ("ice: Hide bus-info in ethtool for PRs in switchdev mode") was a workaround for lshw tool displaying incorrect descriptions for port representors and PF in switchdev mode. Now the issue has been fixed in the lshw tool itself [1]. Removing the workaround can be considered a regression, as the user might be running older, unpatched lshw version. However, another important change (ice: link representors to PCI device, which improves port representor netdev naming with SET_NETDEV_DEV) also causes the same "regression" as removing the workaround, i.e. unpatched lshw is able to access bus-info information (this time not via ethtool) and the bug can occur. Therefore, the workaround no longer prevents the bug and can be removed.

2022-05-06net: don't allow user space to lift the device limitsJakub Kicinski
Up until commit 46e6b992c250 ("rtnetlink: allow GSO maximums to be set on device creation") the gso_max_segs and gso_max_size of a device were not controlled from user space. The quoted commit added the ability to control them because of the following setup: netns A | netns B veth<->veth eth0 If eth0 has TSO limitations and user wants to efficiently forward traffic between eth0 and the veths they should copy the TSO limitations of eth0 onto the veths. This would happen automatically for macvlans or ipvlan but veth users are not so lucky (given the loose coupling). Unfortunately the commit in question allowed users to also override the limits on real HW devices. It may be useful to control the max GSO size and someone may be using that ability (not that I know of any user), so create a separate set of knobs to reliably record the TSO limitations. Validate the user requests. Signed-off-by: Jakub Kicinski <kuba@kernel.org> Signed-off-by: David S. Miller <davem@davemloft.net>

2022-05-06platform/surface: aggregator: Fix initialization order when compiling as ↵Maximilian Luz
builtin module When building the Surface Aggregator Module (SAM) core, registry, and other SAM client drivers as builtin modules (=y), proper initialization order is not guaranteed. Due to this, client driver registration (triggered by device registration in the registry) races against bus initialization in the core. If any attempt is made at registering the device driver before the bus has been initialized (i.e. if bus initialization fails this race) driver registration will fail with a message similar to: Driver surface_battery was unable to register with bus_type surface_aggregator because the bus was not initialized Switch from module_init() to subsys_initcall() to resolve this issue. Note that the serdev subsystem uses postcore_initcall() so we are still able to safely register the serdev device driver for the core.

2022-05-06platform/x86: thinkpad_acpi: Add a s2idle resume quirk for a number of laptopsMario Limonciello
Lenovo laptops that contain NVME SSDs across a variety of generations have trouble resuming from suspend to idle when the IOMMU translation layer is active for the NVME storage device. This generally manifests as a large resume delay or page faults. These delays and page faults occur as a result of a Lenovo BIOS specific SMI that runs during the D3->D0 transition on NVME devices. This SMI occurs because of a flag that is set during resume by Lenovo firmware: ``` OperationRegion (PM80, SystemMemory, 0xFED80380, 0x10) Field (PM80, AnyAcc, NoLock, Preserve) { SI3R, 1 } Method (_ON, 0, NotSerialized) // _ON_: Power On { TPST (0x60D0) If ((DAS3 == 0x00)) { If (SI3R) { TPST (0x60E0) M020 (NBRI, 0x00, 0x00, 0x04, (NCMD | 0x06)) M020 (NBRI, 0x00, 0x00, 0x10, NBAR) APMC = HDSI /* \HDSI */ SLPS = 0x01 SI3R = 0x00 TPST (0x60E1) } D0NV = 0x01 } } ``` Create a quirk that will run early in the resume process to prevent this SMI from running. As any of these machines are fixed, they can be peeled back from this quirk or narrowed down to individual firmware versions.

2022-05-06Merge branch 'nfp-flower-rework'David S. Miller
Simon Horman says: ==================== nfp: flower: decap neighbour table rework Louis Peens says: This patch series reworks the way in which flow rules that outputs to OVS internal ports gets handled by the nfp driver. Previously this made use of a small pre_tun_table, but this only used destination MAC addresses, and made the implicit assumption that there is only a single source MAC":"destination MAC" mapping per tunnel. In hindsight this seems to be a pretty obvious oversight, but this was hidden in plain sight for quite some time. This series changes the implementation to make use of the same Neighbour table for decap that is in use for the tunnel encap solution. It stores any new Neighbour updates in this table. Previously this path was only triggered for encapsulation candidates, and the entries were send and forget, not saved on the host as it is after this series. It also keeps track of any flow rule that outputs to OVS internal ports (and some other criteria not worth mentioning here), very similar to how it was done previously, except now these flows are kept track of in a list. When a new Neighbour entry gets added this list gets iterated for potential matches, in which case the table gets updated with a reference to the flow, and the Neighbour entry on the card gets updated with the relevant host_ctx. The same happens when a new qualifying flow gets added - the Neighbour table gets iterated for applicable matches, and once again the firmware gets updated with the host_ctx when any matches are found. Since this also requires a firmware change we add a new capability bit, and keep the old behaviour in case of older firmware without this bit set. This series starts by doing some preparation, then adding the new list and table entries. Next the functionality to link/unlink these entries are added, and finally this new functionality is enabled by adding the DECAP_V2 bit to the driver feature list. ==================== Signed-off-by: David S.

2022-05-06nfp: flower: link pre_tun flow rules with neigh entriesLouis Peens
Add helper functions that can create links between flow rules and cached neighbour entries. Also add the relevant calls to these functions. * When a new neighbour entry gets added cycle through the saved pre_tun flow list and link any relevant matches. Update the neighbour table on the nfp with this new information. * When a new pre_tun flow rule gets added iterate through the save neighbour entries and link any relevant matches. Once again update the nfp neighbour table with any new links. * Do the inverse when deleting - remove any created links and also inform the nfp of this.

2022-05-06nfp: flower: rework tunnel neighbour configurationLouis Peens
This patch updates the way in which the tunnel neighbour entries are handled. Previously they were mostly send-and-forget, with just the destination IP's cached in a list. This update changes to a scheme where the neighbour entry information is stored in a hash table. The reason for this is that the neighbour table will now also be used on the decapsulation path, whereas previously it was only used for encapsulation. We need to save more of the neighbour information in order to link them with flower flows in follow up patches. Updating of the neighbour table is now also handled by the same function, instead of separate *_write_neigh_vX functions.

2022-05-06nfp: flower: fixup ipv6/ipv4 route lookup for neigh eventsLouis Peens
When a callback is received to invalidate a neighbour entry there is no need to try and populate any other flow information. Only the flowX->daddr information is needed as lookup key to delete an entry from the NFP neighbour table. Fix this by only doing the lookup if the callback is for a new entry. As part of this cleanup remove the setting of flow6.flowi6_proto, as this is not needed either, it looks to be a possible leftover from a previous implementation.

Make sure that the rule also matches on source MAC address. On top of that also now save the src and dst MAC addresses similar to how vlan_tci is saved - this will be used in later comparisons with neighbour entries. Indicate if the flow matched on ipv4 or ipv6. Populate the vlan_tpid field that got added to the pre_run_rule struct as well.

2022-05-06nfp: flower: add infrastructure for pre_tun reworkLouis Peens
The previous implementation of using a pre_tun_table for decap has some limitations, causing flows to end up unoffloaded when in fact we are able to offload them. This is because the pre_tun_table does not have enough matching resolution. The next step is to instead make use of the neighbour table which already exists for the encap direction. This patch prepares for this by: - Moving nfp_tun_neigh/_v6 to main.h. - Creating two new "wrapping" structures, one to keep track of neighbour entries (previously they were send-and-forget), and another to keep track of pre_tun flows. - Create a new list in nfp_flower_priv to keep track of pre_tunnel flows - Create a new table in nfp_flower_priv to keep track of next neighbour entries - Initialising and destroying these new list/tables - Extending nfp_fl_payload->pre_tun_rule to save more information for future use.
