2022-05-02vsock/virtio: add support for device suspend/resumeStefano Garzarella1-0/+47
Implement .freeze and .restore callbacks of struct virtio_driver to support device suspend/resume. During suspension all connected sockets are reset and VQs deleted. During resume the VQs are re-initialized. Reported by: Vilas R K <vilas.r.k@intel.com> Signed-off-by: Stefano Garzarella <sgarzare@redhat.com> Acked-by: Michael S.

2022-05-02selftests: forwarding: add Per-Stream Filtering and Policing test for OcelotVladimir Oltean2-0/+562
The Felix VSC9959 switch in NXP LS1028A supports the tc-gate action which enforced time-based access control per stream. A stream as seen by this switch is identified by {MAC DA, VID}. We use the standard forwarding selftest topology with 2 host interfaces and 2 switch interfaces. The host ports must require timestamping non-IP packets and supporting tc-etf offload, for isochron to work. The isochron program monitors network sync status (ptp4l, phc2sys) and deterministically transmits packets to the switch such that the tc-gate action either (a) always accepts them based on its schedule, or (b) always drops them. I tried to keep as much of the logic that isn't specific to the NXP LS1028A in a new tsn_lib.sh, for future reuse. This covers synchronization using ptp4l and phc2sys, and isochron. The cycle-time chosen for this selftest isn't particularly impressive (and the focus is the functionality of the switch), but I didn't really know what to do better, considering that it will mostly be run during debugging sessions, various kernel bloatware would be enabled, like lockdep, KASAN, etc, and we certainly can't run any races with those on. I tried to look through the kselftest framework for other real time applications and didn't really find any, so I'm not sure how better to prepare the environment in case we want to go for a lower cycle time. At the moment, the only thing the selftest is ensuring is that dynamic frequency scaling is disabled on the CPU that isochron runs on. It would probably be useful to have a blacklist of kernel config options (checked through zcat /proc/config.gz) and some cyclictest scripts to run beforehand, but I saw none of those.

2022-05-02carl9170: tx: fix an incorrect use of list iteratorXiaomeng Tong1-0/+3
If the previous list_for_each_entry_continue_rcu() don't exit early (no goto hit inside the loop), the iterator 'cvif' after the loop will be a bogus pointer to an invalid structure object containing the HEAD (&ar->vif_list). As a result, the use of 'cvif' after that will lead to a invalid memory access (i.e., 'cvif->id': the invalid pointer dereference when return back to/after the callsite in the carl9170_update_beacon()). The original intention should have been to return the valid 'cvif' when found in list, NULL otherwise. So just return NULL when no entry found, to fix this bug.

2022-05-02ath11k: Add support for WCN6750 deviceManikanta Pubbisetty4-13/+158
WCN6750 is non-DBS 2x2 11AX chipset. Unlike QCA6390 which is a DBS (dual band simultaneous) solution (2 LMACs), WCN6750 has a single LMAC supporting 2G, 5G and 6G bands but will operate only on one band at any given point. WCN6750 is a PCIe based solution, but it is attached to the WPSS (Wireless Processor SubSystem) Q6 processor, hence it is enumerated by the Q6 processor. It is registered to the APSS processor (Application Processor SubSystem) as a platform device(AHB) and remoteproc APIs are used to boot up or shutdown the device like other AHB devices. Also, Device information like BAR and it's size is not known to the APSS processor as the chip is enumerated by WPSS Q6. These details are fetched over QMI. STA and AP modes are supported. Verified basic connectivity and ping in both the modes. An important point to note is that though WCN6750 is a PCIe device, it cannot be attached to any other platform except on Qualcomm Snapdragon SoCs due to the aforementioned reasons.

In the case of WCN6750, FW doesn't request for DDR memory via QMI, instead it uses a fixed 12MB reserved Memory region in the DDR which is called as MSA region. As a result, QMI message sequence is not same as other ath11k supported devices. Also, M3 firmware will be bundled into the FW and will be downloaded to the target as part of Q6 boot.

WCN6750 is the WLAN chip on Qualcomm Snapdragon SoC SC7280; Though being a PCIe based solution, it is not attached to the APSS processor (Application Processor SubSystem), it is instead attached to another tiny processor called WPSS Q6 processor (Wireless Processor SubSystem) on the SC7280 MSM, where the WLAN firmware runs, and it is the WLAN firmware running on the Q6 processor which enumerates WCN6750, as a result APPS processor would never know such a device being present in the system and would not detect the WCN6750 hardware unless and otherwise WCN6750 is registered as a platform device. This is the reason behind adding WCN6750 WLAN node in the device tree. Add WCN6750 wireless driver support, its based on ath11k driver.

WMI_UPDATE_STATS_EVENTID reported from firmware, at this moment, the ieee80211_sta can not be found again because it has remove from list in step2 and also peer->sta is clear in step3. 6. in __sta_info_destroy_part2(), it then called cleanup_single_sta()-> sta_info_free()->kfree(sta), at this moment, the ieee80211_sta is freed in memory, then the failed log will not happen because function ath11k_mac_op_sta_state() will not be called. Actually this print log is not a real error, it is only to skip parse the info, so change to skip print by default debug setting.

Andrew Lunn says: ==================== Use MMD/C45 helpers MDIO busses can perform two sorts of bus transaction, defined in clause 22 and clause 45 of 802.3. This results in two register addresses spaces. The current driver structure for indicating if C22 or C45 should be used is messy, and many C22 only bus drivers will wrongly interpret a C45 transaction as a C22 transaction. This patchset is a preparation step to cleanup the situation. It converts MDIO bus users to make use of existing _mmd and _c45 helpers to perform accesses to C45 registers. This will later allow C45 and C22 to be kept separate. ==================== Link: https://lore.kernel.org/r/20220430173037.156823-1-andrew@lunn.ch Signed-off-by: Paolo Abeni <pabeni@redhat.com>

2022-05-02nfp: support VxLAN inner TSO with GSO_PARTIAL offloadFei Qin1-2/+6
VxLAN belongs to UDP-based encapsulation protocol. Inner TSO for VxLAN packet with udpcsum requires offloading of outer header csum. The device doesn't support outer header csum offload. However, inner TSO for VxLAN with udpcsum can still work with GSO_PARTIAL offload, which means outer udp csum computed by stack and inner tcp segmentation finished by hardware. Thus, the patch enable features "NETIF_F_GSO_UDP_TUNNEL_CSUM" and "NETIF_F_GSO_PARTIAL" and set gso_partial_features.

Since o_seqno is now atomic_t, we can always turn on NETIF_F_LLTX for [IP6]GRE[TAP] devices, since we no longer need the TX lock (&txq->_xmit_lock). We could probably do the same thing to [IP6]ERSPAN devices as well, but I'm not familiar with them yet. For example, ERSPAN devices are initialized as |= GRE_FEATURES in erspan_tunnel_init(), but I don't see IP6ERSPAN devices being initialized as |= GRE6_FEATURES. Where should we initialize IP6ERSPAN devices' ->features? Please suggest if I'm missing something, thanks!
