2022-02-09x86/PCI: revert "Ignore E820 reservations for bridge windows on newer systems"Hans de Goede1-22/+1
Commit 7f7b4236f204 ("x86/PCI: Ignore E820 reservations for bridge windows on newer systems") fixes the touchpad not working on laptops like the Lenovo IdeaPad 3 15IIL05 and the Lenovo IdeaPad 5 14IIL05, as well as fixing thunderbolt hotplug issues on the Lenovo Yoga C940. Unfortunately it turns out that this is causing issues with suspend/resume on Lenovo ThinkPad X1 Carbon Gen 2 laptops. So, per the no regressions policy, rever this. Note I'm looking into another fix for the issues this fixed.

2022-02-09ACPI/IORT: Check node revision for PMCG resourcesRobin Murphy1-3/+11
The original version of the IORT PMCG definition had an oversight wherein there was no way to describe the second register page for an implementation using the recommended RELOC_CTRS feature. Although the spec was fixed, and the final patches merged to ACPICA and Linux written against the new version, it seems that some old firmware based on the original revision has survived and turned up in the wild. Add a check for the original PMCG definition, and avoid filling in the second memory resource with nonsense if so. Otherwise it is likely that something horrible will happen when the PMCG driver attempts to probe.

2022-02-09btrfs: get rid of warning on transaction commit when using flushoncommitFilipe Manana1-2/+10
When using the flushoncommit mount option, during almost every transaction commit we trigger a warning from __writeback_inodes_sb_nr(): $ cat fs/fs-writeback.c: (...) static void __writeback_inodes_sb_nr(struct super_block *sb, ... { (...)

This change was made by commit ce8ea7cc6eb313 ("btrfs: don't call btrfs_start_delalloc_roots in flushoncommit"). After that change we started producing that warning, and every now and then a user reports this since the warning happens too often, it spams dmesg/syslog, and a user is unsure if this reflects any problem that might compromise the filesystem's reliability. We can not just lock the sb->s_umount semaphore before calling writeback_inodes_sb(), because that would at least deadlock with filesystem freezing, since at fs/super.c:freeze_super() sync_filesystem() is called while we are holding that semaphore in write mode, and that can trigger a transaction commit, resulting in a deadlock. It would also trigger the same type of deadlock in the unmount path. Possibly, it could also introduce some other locking dependencies that lockdep would report. To fix this call try_to_writeback_inodes_sb() instead of writeback_inodes_sb(), because that will try to read lock sb->s_umount and then will only call writeback_inodes_sb() if it was able to lock it. This is fine because the cases where it can't read lock sb->s_umount are during a filesystem unmount or during a filesystem freeze - in those cases sb->s_umount is write locked and sync_filesystem() is called, which calls writeback_inodes_sb(). In other words, in all cases where we can't take a read lock on sb->s_umount, writeback is already being triggered elsewhere. An alternative would be to call btrfs_start_delalloc_roots() with a number of pages different from LONG_MAX, for example matching the number of delalloc bytes we currently have, in which case we would end up starting all delalloc with filemap_fdatawrite_wbc() and not with an async flush via filemap_flush() - that is only possible after the rather recent commit e076ab2a2ca70a ("btrfs: shrink delalloc pages instead of full inodes"). However that creates a whole new can of worms due to new lock dependencies, which lockdep complains, like for example: [ 8948.247280] ====================================================== [ 8948.247823] WARNING: possible circular locking dependency detected [ 8948.248353] 5.17.0-rc1-btrfs-next-111 #1 Not tainted [ 8948.248786] ------------------------------------------------------ [ 8948.249320] kworker/u16:18/933570 is trying to acquire lock: [ 8948.249812] ffff9b3de1591690 (sb_internal#2){.+.+}-{0:0}, at: find_free_extent+0x141e/0x1590 [btrfs] [ 8948.250638] but task is already holding lock: [ 8948.251140] ffff9b3e09c717d8 (&root->delalloc_mutex){+.+.}-{3:3}, at: start_delalloc_inodes+0x78/0x400 [btrfs] [ 8948.252018] which lock already depends on the new lock.

2022-02-09btrfs: defrag: don't try to defrag extents which are under writebackQu Wenruo1-0/+4
Once we start writeback (have called btrfs_run_delalloc_range()), we allocate an extent, create an extent map point to that extent, with a generation of (u64)-1, created the ordered extent and then clear the DELALLOC bit from the range in the inode's io tree. Such extent map can pass the first call of defrag_collect_targets(), as its generation is (u64)-1, meets any possible minimal generation check. And the range will not have DELALLOC bit, also passing the DELALLOC bit check. It will only be re-checked in the second call of defrag_collect_targets(), which will wait for writeback. But at that stage we have already spent our time waiting for some IO we may or may not want to defrag. Let's reject such extents early so we won't waste our time.

2022-02-09Fix regression due to "fs: move binfmt_misc sysctl to its own file"Domenico Andreoli2-5/+3
Commit 3ba442d5331f ("fs: move binfmt_misc sysctl to its own file") did not go unnoticed, binfmt-support stopped to work on my Debian system since v5.17-rc2 (did not check with -rc1). The existance of the /proc/sys/fs/binfmt_misc is a precondition for attempting to mount the binfmt_misc fs, which in turn triggers the autoload of the binfmt_misc module. Without it, no module is loaded and no binfmt is available at boot. Building as built-in or manually loading the module and mounting the fs works fine, it's therefore only a matter of interaction with user-space. I could try to improve the Debian systemd configuration but I can't say anything about the other distributions. This patch restores a working system right after boot.

2022-02-09ice: Add ability for PF admin to enable VF VLAN pruningBrett Creeley4-2/+40
VFs by default are able to see all tagged traffic regardless of trust and VLAN filters. Based on legacy devices (i.e. ixgbe, i40e), customers expect VFs to receive all VLAN tagged traffic with a matching destination MAC. Add an ethtool private flag 'vf-vlan-pruning' and set the default to off so VFs will receive all VLAN traffic directed towards them. When the flag is turned on, VF will only be able to receive untagged traffic or traffic with VLAN tags it has created interfaces for. Also, the flag cannot be changed while any VFs are allocated. This was done to simplify the implementation. So, if this flag is needed, then the PF admin must enable it. If the user tries to enable the flag while VFs are active, then print an unsupported message with the vf-vlan-pruning flag included. In case multiple flags were specified, this makes it clear to the user which flag failed.

2022-02-09ice: Advertise 802.1ad VLAN filtering and offloads for PF netdevBrett Creeley2-49/+238
In order for the driver to support 802.1ad VLAN filtering and offloads, it needs to advertise those VLAN features and also support modifying those VLAN features, so make the necessary changes to ice_set_netdev_features(). By default, enable CTAG insertion/stripping and CTAG filtering for both Single and Double VLAN Modes (SVM/DVM). Also, in DVM, enable STAG filtering by default. This is done by setting the feature bits in netdev->features. Also, in DVM, support toggling of STAG insertion/stripping, but don't enable them by default. This is done by setting the feature bits in netdev->hw_features. Since 802.1ad VLAN filtering and offloads are only supported in DVM, make sure they are not enabled by default and that they cannot be enabled during runtime, when the device is in SVM. Add an implementation for the ndo_fix_features() callback. This is needed since the hardware cannot support multiple VLAN ethertypes for VLAN insertion/stripping simultaneously and all supported VLAN filtering must either be enabled or disabled together. Disable inner VLAN stripping by default when DVM is enabled. If a VSI supports stripping the inner VLAN in DVM, then it will have to configure that during runtime. For example if a VF is configured in a port VLAN while DVM is enabled it will be allowed to offload inner VLANs.

2022-02-09ice: Support configuring the device to Double VLAN ModeBrett Creeley17-59/+996
In order to support configuring the device in Double VLAN Mode (DVM), the DDP and FW have to support DVM. If both support DVM, the PF that downloads the package needs to update the default recipes, set the VLAN mode, and update boost TCAM entries. To support updating the default recipes in DVM, add support for updating an existing switch recipe's lkup_idx and mask. This is done by first calling the get recipe AQ (0x0292) with the desired recipe ID. Then, if that is successful update one of the lookup indices (lkup_idx) and its associated mask if the mask is valid otherwise the already existing mask will be used. The VLAN mode of the device has to be configured while the global configuration lock is held while downloading the DDP, specifically after the DDP has been downloaded. If supported, the device will default to DVM.

Add support for the VF driver to be able to request VIRTCHNL_VF_OFFLOAD_VLAN_V2, negotiate its VLAN capabilities via VIRTCHNL_OP_GET_OFFLOAD_VLAN_V2_CAPS, add/delete VLAN filters, and enable/disable VLAN offloads. VFs supporting VIRTCHNL_OFFLOAD_VLAN_V2 will be able to use the following virtchnl opcodes: VIRTCHNL_OP_GET_OFFLOAD_VLAN_V2_CAPS VIRTCHNL_OP_ADD_VLAN_V2 VIRTCHNL_OP_DEL_VLAN_V2 VIRTCHNL_OP_ENABLE_VLAN_STRIPPING_V2 VIRTCHNL_OP_DISABLE_VLAN_STRIPPING_V2 VIRTCHNL_OP_ENABLE_VLAN_INSERTION_V2 VIRTCHNL_OP_DISABLE_VLAN_INSERTION_V2 Legacy VF drivers may expect the initial VLAN stripping settings to be configured by the PF, so the PF initializes VLAN stripping based on the VIRTCHNL_OP_GET_VF_RESOURCES opcode. However, with VLAN support via VIRTCHNL_VF_OFFLOAD_VLAN_V2, this function is only expected to be used for VFs that only support VIRTCHNL_VF_OFFLOAD_VLAN, which will only be supported when a port VLAN is configured. Update the function based on the new expectations. Also, change the message when the PF can't enable/disable VLAN stripping to a dev_dbg() as this isn't fatal. When a VF isn't in a port VLAN and it only supports VIRTCHNL_VF_OFFLOAD_VLAN when Double VLAN Mode (DVM) is enabled, then the PF needs to reject the VIRTCHNL_VF_OFFLOAD_VLAN capability and configure the VF in software only VLAN mode. To do this add the new function ice_vf_vsi_cfg_legacy_vlan_mode(), which updates the VF's inner and outer ice_vsi_vlan_ops functions and sets up software only VLAN mode.

2022-02-09ice: Add hot path support for 802.1Q and 802.1ad VLAN offloadsBrett Creeley9-22/+87
Currently the driver only supports 802.1Q VLAN insertion and stripping. However, once Double VLAN Mode (DVM) is fully supported, then both 802.1Q and 802.1ad VLAN insertion and stripping will be supported. Unfortunately the VSI context parameters only allow for one VLAN ethertype at a time for VLAN offloads so only one or the other VLAN ethertype offload can be supported at once. To support this, multiple changes are needed. Rx path changes: [1] In DVM, the Rx queue context l2tagsel field needs to be cleared so the outermost tag shows up in the l2tag2_2nd field of the Rx flex descriptor. In Single VLAN Mode (SVM), the l2tagsel field should remain 1 to support SVM configurations. [2] Modify the ice_test_staterr() function to take a __le16 instead of the ice_32b_rx_flex_desc union pointer so this function can be used for both rx_desc->wb.status_error0 and rx_desc->wb.status_error1. [3] Add the new inline function ice_get_vlan_tag_from_rx_desc() that checks if there is a VLAN tag in l2tag1 or l2tag2_2nd. [4] In ice_receive_skb(), add a check to see if NETIF_F_HW_VLAN_STAG_RX is enabled in netdev->features. If it is, then this is the VLAN ethertype that needs to be added to the stripping VLAN tag. Since ice_fix_features() prevents CTAG_RX and STAG_RX from being enabled simultaneously, the VLAN ethertype will only ever be 802.1Q or 802.1ad. Tx path changes: [1] In DVM, the VLAN tag needs to be placed in the l2tag2 field of the Tx context descriptor. The new define ICE_TX_FLAGS_HW_OUTER_SINGLE_VLAN was added to the list of tx_flags to handle this case. [2] When the stack requests the VLAN tag to be offloaded on Tx, the driver needs to set either ICE_TX_FLAGS_HW_OUTER_SINGLE_VLAN or ICE_TX_FLAGS_HW_VLAN, so the tag is inserted in l2tag2 or l2tag1 respectively. To determine which location to use, set a bit in the Tx ring flags field during ring allocation that can be used to determine which field to use in the Tx descriptor. In DVM, always use l2tag2, and in SVM, always use l2tag1.

2022-02-09ice: Add outer_vlan_ops and VSI specific VLAN ops implementationsBrett Creeley16-86/+813
Add a new outer_vlan_ops member to the ice_vsi structure as outer VLAN ops are only available when the device is in Double VLAN Mode (DVM). Depending on the VSI type, the requirements for what operations to use/allow differ. By default all VSI's have unsupported inner and outer VSI VLAN ops. This implementation was chosen to prevent unexpected crashes due to null pointer dereferences. Instead, if a VSI calls an unsupported op, it will just return -EOPNOTSUPP. Add implementations to support modifying outer VLAN fields for VSI context. This includes the ability to modify VLAN stripping, insertion, and the port VLAN based on the outer VLAN handling fields of the VSI context. These functions should only ever be used if DVM is enabled because that means the firmware supports the outer VLAN fields in the VSI context. If the device is in DVM, then always use the outer_vlan_ops, else use the vlan_ops since the device is in Single VLAN Mode (SVM). Also, move adding the untagged VLAN 0 filter from ice_vsi_setup() to ice_vsi_vlan_setup() as the latter function is specific to the PF and all other VSI types that need an untagged VLAN 0 filter already do this in their specific flows. Without this change, Flow Director is failing to initialize because it does not implement any VSI VLAN ops.

Add the "inner" naming to existing VLAN operations to distinguish them from the upcoming outer values and functions. Some spacing adjustments are made to align values. Note that the inner is not talking about a tunneled VLAN, but the second VLAN in the packet. For SVM the driver uses inner or single VLAN filtering and offloads and in Double VLAN Mode the driver uses the inner filtering and offloads for SR-IOV VFs in port VLANs in order to support offloading the guest VLAN while a port VLAN is configured.

This fixes dtbs_check warning: arch/arm64/boot/dts/altera/socfpga_stratix10_socdk.dt.yaml: soc: timer: {'compatible': ['arm,armv8-timer'], 'interrupts': [[1, 13, 3848], [1, 14, 3848], [1, 11, 3848], [1, 10, 3848]]} should not be valid under {'type': 'object'} From schema: dtschema/schemas/simple-bus.yaml Signed-off-by: Krzysztof Kozlowski <krzysztof.kozlowski@canonical.com> Signed-off-by: Dinh Nguyen <dinguyen@kernel.org>
