2024-06-18wifi: wlcore: correctness fix fwlog readingRussell King (Oracle)
Fix the calculation of clear_offset, which may overflow the end of the buffer. However, this is harmless if it does because in that case it will be recalculated when we copy the chunk of messages at the start of the buffer.

2024-06-18net: phy: mxl-gpy: Remove interrupt mask clearing from config_initRaju Lakkaraju
When the system resumes from sleep, the phy_init_hw() function invokes config_init(), which clears all interrupt masks and causes wake events to be lost in subsequent wake sequences. Remove interrupt mask clearing from config_init() and preserve relevant masks in config_intr().

2024-06-18wifi: wlcore: fix wlcore AP modeRussell King (Oracle)
Using wl183x devices in AP mode with various firmwares is not stable. The driver currently adds a station to firmware with basic rates when it is first known to the stack using the CMD_ADD_PEER command. Once the station has finished authorising, another CMD_ADD_PEER command is issued to update the firmware with the rates the station can use. However, after a random amount of time, the firmware ignores the power management nullfunc frames from the station, and tries to send packets while the station is asleep, resulting in lots of retries dropping down in rate due to no response. This restricts the available bandwidth. With this happening with several stations, the user visible effect is the latency of interactive connections increases significantly, packets get dropped, and in general the WiFi connections become unreliable and unstable. Eventually, the firmware transmit queue appears to get stuck - with packets and blocks allocated that never clear. TI have a couple of patches that address this, but they touch the mac80211 core to disable NL80211_FEATURE_FULL_AP_CLIENT_STATE for *all* wireless drivers, which has the effect of not adding the station to the stack until later when the rates are known. This is a sledge hammer approach to solving the problem. The solution implemented here has the same effect, but without impacting all drivers. We delay adding the station to firmware until it has been authorised in the driver, and correspondingly remove the station when unwinding from authorised state. Adding the station to firmware allocates a hlid, which will now happen later than the driver expects. Therefore, we need to track when this happens so that we transmit using the correct hlid. This patch is an equivalent fix to these two patches in TI's wilink8-wlan repository: https://git.ti.com/cgit/wilink8-wlan/build-utilites/tree/patches/kernel_patches/4.19.38/0004-mac80211-patch.patch?h=r8.9&id=a2ee50aa5190ed3b334373d6cd09b1bff56ffcf7 https://git.ti.com/cgit/wilink8-wlan/build-utilites/tree/patches/kernel_patches/4.19.38/0005-wlcore-patch.patch?h=r8.9&id=a2ee50aa5190ed3b334373d6cd09b1bff56ffcf7 Reported-by: Russell King (Oracle) <rmk+kernel@armlinux.org.uk> Co-developed-by: Johannes Berg <johannes.berg@intel.com> Tested-by: Russell King (Oracle) <rmk+kernel@armlinux.org.uk> Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: Russell King (Oracle) <rmk+kernel@armlinux.org.uk> Signed-off-by: Kalle Valo <kvalo@kernel.org> Link: https://msgid.link/E1sClp4-00Evu7-8v@rmk-PC.armlinux.org.uk

2024-06-17s390/virtio_ccw: Fix config change notificationsHalil Pasic
Commit e3e9bda38e6d ("s390/virtio_ccw: use DMA handle from DMA API") broke configuration change notifications for virtio-ccw by putting the DMA address of *indicatorp directly into ccw->cda disregarding the fact that if !!(vcdev->is_thinint) then the function virtio_ccw_register_adapter_ind() will overwrite that ccw->cda value with the address of the virtio_thinint_area so it can actually set up the adapter interrupts via CCW_CMD_SET_IND_ADAPTER. Thus we end up pointing to the wrong object for both CCW_CMD_SET_IND if setting up the adapter interrupts fails, and for CCW_CMD_SET_CONF_IND regardless whether it succeeds or fails. To fix this, let us save away the dma address of *indicatorp in a local variable, and copy it to ccw->cda after the "vcdev->is_thinint" branch.

Raptor Lake models Dell laptops with IPU6 camera (the Tiger Lake, Alder Lake and Raptor Lake generations) have broken ACPI MIPI DISCO information (this results from an OEM attempt to make Linux work by supplying it with custom data in the ACPI tables which has never been supported in the mainline). Instead of adding a lot of DMI quirks for this, check for Dell platforms based on the processor generations in question and drop the ACPI graph port nodes, likely to be created with the help of invalid data, on all of them.

2024-06-17ACPICA: Revert "ACPICA: avoid Info: mapping multiple BARs. Your kernel is fine."Raju Rangoju
Undo the modifications made in commit d410ee5109a1 ("ACPICA: avoid "Info: mapping multiple BARs. Your kernel is fine.""). The initial purpose of this commit was to stop memory mappings for operation regions from overlapping page boundaries, as it can trigger warnings if different page attributes are present. However, it was found that when this situation arises, mapping continues until the boundary's end, but there is still an attempt to read/write the entire length of the map, leading to a NULL pointer deference. For example, if a four-byte mapping request is made but only one byte is mapped because it hits the current page boundary's end, a four-byte read/write attempt is still made, resulting in a NULL pointer deference. Instead, map the entire length, as the ACPI specification does not mandate that it must be within the same page boundary. It is permissible for it to be mapped across different regions.

2024-06-17x86/sev: Extend the config-fs attestation support for an SVSMTom Lendacky
When an SVSM is present, the guest can also request attestation reports from it. These SVSM attestation reports can be used to attest the SVSM and any services running within the SVSM. Extend the config-fs attestation support to provide such. This involves creating four new config-fs attributes: - 'service-provider' (input) This attribute is used to determine whether the attestation request should be sent to the specified service provider or to the SEV firmware. The SVSM service provider is represented by the value 'svsm'. - 'service_guid' (input) Used for requesting the attestation of a single service within the service provider. A null GUID implies that the SVSM_ATTEST_SERVICES call should be used to request the attestation report. A non-null GUID implies that the SVSM_ATTEST_SINGLE_SERVICE call should be used. - 'service_manifest_version' (input) Used with the SVSM_ATTEST_SINGLE_SERVICE call, the service version represents a specific service manifest version be used for the attestation report. - 'manifestblob' (output) Used to return the service manifest associated with the attestation report. Only display these new attributes when running under an SVSM.

2024-06-17x86/sev: Take advantage of configfs visibility support in TSMTom Lendacky
The TSM attestation report support provides multiple configfs attribute types (both for standard and binary attributes) to allow for additional attributes to be displayed for SNP as compared to TDX. With the ability to hide attributes via configfs, consolidate the multiple attribute groups into a single standard attribute group and a single binary attribute group. Modify the TDX support to hide the attributes that were previously "hidden" as a result of registering the selective attribute groups.
