2022-03-09x86/boot: Fix memremap of setup_indirect structuresRoss Philipson
As documented, the setup_indirect structure is nested inside the setup_data structures in the setup_data list. The code currently accesses the fields inside the setup_indirect structure but only the sizeof(struct setup_data) is being memremapped. No crash occurred but this is just due to how the area is remapped under the covers. Properly memremap both the setup_data and setup_indirect structures in these cases before accessing them.

Michal ensures netdev features are properly updated to reflect VLAN changes received from PF and adds an additional flag for MSI-X reinitialization as further differentiation of reinitialization operations is needed for iavf. Jake stops disabling of VFs due to failed virtchannel responses for i40e and ice driver. Dave moves MTU event notification to the service task to prevent issues with RTNL lock for ice. Christophe Jaillet corrects an allocation to GFP_ATOMIC instead of GFP_KERNEL for ice.

2022-03-08tipc: fix incorrect order of state message data sanity checkTung Nguyen
When receiving a state message, function tipc_link_validate_msg() is called to validate its header portion. Then, its data portion is validated before it can be accessed correctly. However, current data sanity check is done after the message header is accessed to update some link variables. This commit fixes this issue by moving the data sanity check to the beginning of state message handling and right after the header sanity check.

Commit 9d497e2941c3 ("block: don't protect submit_bio_checks by q_usage_counter") moved blk_mq_attempt_bio_merge and rq_qos_throttle calls out of q_usage_counter protection. However, these functions require q_usage_counter protection. The blk_mq_attempt_bio_merge call without the protection resulted in blktests block/005 failure with KASAN null- ptr-deref or use-after-free at bio merge.

2022-03-08ice: Fix error with handling of bonding MTUDave Ertman
When a bonded interface is destroyed, .ndo_change_mtu can be called during the tear-down process while the RTNL lock is held. This is a problem since the auxiliary driver linked to the LAN driver needs to be notified of the MTU change, and this requires grabbing a device_lock on the auxiliary_device's dev. Currently this is being attempted in the same execution context as the call to .ndo_change_mtu which is causing a dead-lock. Move the notification of the changed MTU to a separate execution context (watchdog service task) and eliminate the "before" notification.

2022-03-08ice: stop disabling VFs due to PF error responsesJacob Keller
The ice_vc_send_msg_to_vf function has logic to detect "failure" responses being sent to a VF. If a VF is sent more than ICE_DFLT_NUM_INVAL_MSGS_ALLOWED then the VF is marked as disabled. Almost identical logic also existed in the i40e driver. This logic was added to the ice driver in commit 1071a8358a28 ("ice: Implement virtchnl commands for AVF support") which itself copied from the i40e implementation in commit 5c3c48ac6bf5 ("i40e: implement virtual device interface"). Neither commit provides a proper explanation or justification of the check. In fact, later commits to i40e changed the logic to allow bypassing the check in some specific instances. The "logic" for this seems to be that error responses somehow indicate a malicious VF. This is not really true. The PF might be sending an error for any number of reasons such as lack of resources, etc. Additionally, this causes the PF to log an info message for every failed VF response which may confuse users, and can spam the kernel log. This behavior is not documented as part of any requirement for our products and other operating system drivers such as the FreeBSD implementation of our drivers do not include this type of check. In fact, the change from dev_err to dev_info in i40e commit 18b7af57d9c1 ("i40e: Lower some message levels") explains that these messages typically don't actually indicate a real issue. It is quite likely that a user who hits this in practice will be very confused as the VF will be disabled without an obvious way to recover. We already have robust malicious driver detection logic using actual hardware detection mechanisms that detect and prevent invalid device usage. Remove the logic since its not a documented requirement and the behavior is not intuitive.

2022-03-08i40e: stop disabling VFs due to PF error responsesJacob Keller
The i40e_vc_send_msg_to_vf_ex (and its wrapper i40e_vc_send_msg_to_vf) function has logic to detect "failure" responses sent to the VF. If a VF is sent more than I40E_DEFAULT_NUM_INVALID_MSGS_ALLOWED, then the VF is marked as disabled. In either case, a dev_info message is printed stating that a VF opcode failed. This logic originates from the early implementation of VF support in commit 5c3c48ac6bf5 ("i40e: implement virtual device interface"). That commit did not go far enough. The "logic" for this behavior seems to be that error responses somehow indicate a malicious VF. This is not really true. The PF might be sending an error for any number of reasons such as lacking resources, an unsupported operation, etc. This does not indicate a malicious VF. We already have a separate robust malicious VF detection which relies on hardware logic to detect and prevent a variety of behaviors. There is no justification for this behavior in the original implementation. In fact, a later commit 18b7af57d9c1 ("i40e: Lower some message levels") reduced the opcode failure message from a dev_err to a dev_info. In addition, recent commit 01cbf50877e6 ("i40e: Fix to not show opcode msg on unsuccessful VF MAC change") changed the logic to allow quieting it for expected failures. That commit prevented this logic from kicking in for specific circumstances. This change did not go far enough. The behavior is not documented nor is it part of any requirement for our products. Other operating systems such as the FreeBSD implementation of our driver do not include this logic. It is clear this check does not make sense, and causes problems which led to ugly workarounds. Fix this by just removing the entire logic and the need for the i40e_vc_send_msg_to_vf_ex function.

2022-03-08ACPI / x86: Work around broken XSDT on Advantech DAC-BJ01 boardMark Cilissen
On this board the ACPI RSDP structure points to both a RSDT and an XSDT, but the XSDT points to a truncated FADT. This causes all sorts of trouble and usually a complete failure to boot after the following error occurs: ACPI Error: Unsupported address space: 0x20 (*/hwregs-*) ACPI Error: AE_SUPPORT, Unable to initialize fixed events (*/evevent-*) ACPI: Unable to start ACPI Interpreter This leaves the ACPI implementation in such a broken state that subsequent kernel subsystem initialisations go wrong, resulting in among others mismapped PCI memory, SATA and USB enumeration failures, and freezes. As this is an older embedded platform that will likely never see any BIOS updates to address this issue and its default shipping OS only complies to ACPI 1.0, work around this by forcing `acpi=rsdt`. This patch, applied on top of Linux 5.10.102, was confirmed on real hardware to fix the issue.

2022-03-08dt-bindings: drm/bridge: anx7625: Revert DPI supportRobert Foss
Revert DPI support from binding. DPI support relies on the bus-type enum which does not yet support Mipi DPI, since no v4l2_fwnode_bus_type has been defined for this bus type. When DPI for anx7625 was initially added, it assumed that V4L2_FWNODE_BUS_TYPE_PARALLEL was the correct bus type for representing DPI, which it is not. In order to prevent adding this mis-usage to the ABI, let's revert the support.

max_seg_size is unsigned int and it can have a value up to 2^32 (for eg:-RZ_DMAC driver sets dma_set_max_seg_size as U32_MAX) When this value is used in min_t() as an integer type, it becomes -1 and the value of sgs becomes 0.

2022-03-08arm64: Ensure execute-only permissions are not allowed without EPANCatalin Marinas
Commit 18107f8a2df6 ("arm64: Support execute-only permissions with Enhanced PAN") re-introduced execute-only permissions when EPAN is available. When EPAN is not available, arch_filter_pgprot() is supposed to change a PAGE_EXECONLY permission into PAGE_READONLY_EXEC. However, if BTI or MTE are present, such check does not detect the execute-only pgprot in the presence of PTE_GP (BTI) or MT_NORMAL_TAGGED (MTE), allowing the user to request PROT_EXEC with PROT_BTI or PROT_MTE. Remove the arch_filter_pgprot() function, change the default VM_EXEC permissions to PAGE_READONLY_EXEC and update the protection_map[] array at core_initcall() if EPAN is detected.

Indeed, from a hardware perspective, the OMAP NAND controller needs the GPMC to work. This led to a robot error which got addressed in fix merge into -rc4. Unfortunately, the approach at this time still used "select" and lead to further build error reports (sparc64:allmodconfig).
