2021-06-22wwan_hwsim: support network interface creationSergey Ryazanov
Add support for networking interface creation via the WWAN core by registering the WWAN netdev creation ops for each simulated WWAN device. Implemented minimalistic netdev support where the xmit callback just consumes all egress skbs. This should help with WWAN network interfaces creation testing.

Now that the MDIO and phylink are supported in the ACPI world, enable to use them in the mvpp2 driver. Ensure a backward compatibility with the firmware whose ACPI description does not contain the necessary elements for the proper phy handling and fall back to relying on the link interrupts instead.

The fail path of efx_ef10_sriov_alloc_vf_vswitching is identical to the full content of efx_ef10_sriov_free_vf_vswitching, so replace it for a single call to efx_ef10_sriov_free_vf_vswitching. Signed-off-by: Íñigo Huguet <ihuguet@redhat.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2021-06-22sfc: explain that "attached" VFs only refer to XenÍñigo Huguet
During SRIOV disabling it is checked wether any VF is currently attached to a guest, using pci_vfs_assigned function. However, this check only works with VFs attached with Xen, not with vfio/KVM. Added comments clarifying this point. Also, replaced manual check of PCI_DEV_FLAGS_ASSIGNED flag and used the helper function pci_is_dev_assigned instead.

2021-06-22sfc: error code if SRIOV cannot be disabledÍñigo Huguet
If SRIOV cannot be disabled during device removal or module unloading, return error code so it can be logged properly in the calling function. Note that this can only happen if any VF is currently attached to a guest using Xen, but not with vfio/KVM. Despite that in that case the VFs won't work properly with PF removed and/or the module unloaded, I have let it as is because I don't know what side effects may have changing it, and also it seems to be the same that other drivers are doing in this situation. In the case of being called during SRIOV reconfiguration, the behavior hasn't changed because the function is called with force=false.

2021-06-22sfc: avoid double pci_remove of VFsÍñigo Huguet
If pci_remove was called for a PF with VFs, the removal of the VFs was called twice from efx_ef10_sriov_fini: one directly with pci_driver->remove and another implicit by calling pci_disable_sriov, which also perform the VFs remove. This was leading to crashing the kernel on the second attempt. Given that pci_disable_sriov already calls to pci remove function, get rid of the direct call to pci_driver->remove from the driver. 2 different ways to trigger the bug: - Create one or more VFs, then attach the PF to a virtual machine (at least with qemu/KVM) - Create one or more VFs, then remove the PF with: echo 1 > /sys/bus/pci/devices/PF_PCI_ID/remove Removing sfc module does not trigger the error, at least for me, because it removes the VF first, and then the PF.

Since peer_he_cap_{mac,phy}info and he_cap_elem.{mac,phy}_cap_info are not the same sizes, memcpy() was reading beyond field boundaries. Instead, correctly cap the copy length and pad out any difference in size (peer_he_cap_macinfo is 8 bytes whereas mac_cap_info is 6, and peer_he_cap_phyinfo is 12 bytes whereas phy_cap_info is 11).

2021-06-22mwifiex: Avoid memset() over-write of WEP key_materialKees Cook
In preparation for FORTIFY_SOURCE performing compile-time and run-time field bounds checking for memset(), avoid intentionally writing across neighboring array fields. When preparing to call mwifiex_set_keyparamset_wep(), key_material is treated very differently from its structure layout (which has only a single struct mwifiex_ie_type_key_param_set). Instead, add a new type to the union so memset() can correctly reason about the size of the structure. Note that the union ("params", 196 bytes) containing key_material was not large enough to hold the target of this memset(): sizeof(struct mwifiex_ie_type_key_param_set) == 60, NUM_WEP_KEYS = 4, so 240 bytes, or 44 bytes past the end of "params". The good news is that it appears that the command buffer, as allocated, is 2048 bytes (MWIFIEX_SIZE_OF_CMD_BUFFER), so no neighboring memory appears to be getting clobbered.

2021-06-22iwlwifi: move error dump to fw utilsJohannes Berg
Conceptually, this belongs more into the firmware utils rather than the mvm opmode, so move the collection and output there. Note that this slightly changes the format of the Status line.

2021-06-22iwlwifi: support loading the reduced power table from UEFILuca Coelho
This new feature allows OEMs to set a special reduced power table in a UEFI variable, which we use to tell the firmware to change the TX power tables. Read the variable and store it in a dram block to pass it to the firmware. We do this as part of the PNVM loading flow.

2021-06-22iwlwifi: fix NUM_IWL_UCODE_TLV_* definitions to avoid sparse errorsLuca Coelho

2021-06-22iwlwifi: pcie: free some DMA memory earlierJohannes Berg
In gen3, after firmware is alive, we no longer need the firmware and image loader images, only the context info itself and PRPH info/scratch need to remain. Call iwl_pcie_ctxt_info_gen3_free() appropriately in the alive callback (iwl_trans_pcie_gen2_fw_alive()) with a new argument indicating whether it can free everything or only partially. The context info and PRPH scratch are also not needed after PNVM load, but we don't have a good hook for freeing after that, so keep them for now.

2021-06-22iwlwifi: mvm: fill phy_data.d1 for no-data RXJohannes Berg
We don't fill in phy_data.d1 in no-data RX, and thus we pretend some data is actually filled in radiotap when it isn't or has default (zero) values. Fill in phy_data.d1 appropriately, and while at it also move the info_type initialization into the initializer.

2021-06-22iwlwifi: pcie: fix context info freeingJohannes Berg
After firmware alive, iwl_trans_pcie_gen2_fw_alive() is called to free the context info. However, on gen3 that will then free the context info with the wrong size. Since we free this allocation later, let it stick around until the device is stopped for now, freeing some of it earlier is a separate change.

2021-06-22iwlwifi: mvm: support LONG_GROUP for WOWLAN_GET_STATUSES versionEmmanuel Grumbach
It's been a while that the firmware uses LONG_GROUP by default and not LEGACY_GROUP. Until now the firmware wrongly advertise the WOWLAN_GET_STATUS command's version with LEGACY_GROUP, but it is now being fixed. In order to support both firmwares, first try to get the version number of the command with the LONG_GROUP and if the firmware didn't advertise the command version with LONG_GROUP, try to get the command version with LEGACY_GROUP.

2021-06-22iwlwifi: support ver 6 of WOWLAN_CONFIGURATION and ver 10 of WOWLAN_GET_STATUSESNaftali Goldstein
These two version updates deprecate the need to set/get the nonqos sequence counter during suspend/resume flow respectively; NICs supporting this version maintain this counter internally and don't lose it during the suspend/resume flow. Note that this means that for such NICs the NON_QOS_TX_COUNTER_CMD is no longer ever sent.
