git://git.kernel.org/pub/scm/linux/kernel/git/saeed/linux Saeed Mahameed says: ==================== mlx5 subfunction support Parav Pandit says: This patchset introduces support for mlx5 subfunction (SF). A subfunction is a lightweight function that has a parent PCI function on which it is deployed. mlx5 subfunction has its own function capabilities and its own resources. This means a subfunction has its own dedicated queues(txq, rxq, cq, eq). These queues are neither shared nor stolen from the parent PCI function. When subfunction is RDMA capable, it has its own QP1, GID table and rdma resources neither shared nor stolen from the parent PCI function. A subfunction has dedicated window in PCI BAR space that is not shared with the other subfunctions or parent PCI function. This ensures that all class devices of the subfunction accesses only assigned PCI BAR space. A Subfunction supports eswitch representation through which it supports tc offloads. User must configure eswitch to send/receive packets from/to subfunction port. Subfunctions share PCI level resources such as PCI MSI-X IRQs with their other subfunctions and/or with its parent PCI function. Subfunction support is discussed in detail in RFC [1] and [2]. RFC [1] and extension [2] describes requirements, design and proposed plumbing using devlink, auxiliary bus and sysfs for systemd/udev support. Functionality of this patchset is best explained using real examples further below. overview: -------- A subfunction can be created and deleted by a user using devlink port add/delete interface. A subfunction can be configured using devlink port function attribute before its activated. When a subfunction is activated, it results in an auxiliary device on the host PCI device where it is deployed. A driver binds to the auxiliary device that further creates supported class devices. example subfunction usage sequence: ----------------------------------- Change device to switchdev mode: $ devlink dev eswitch set pci/0000:06:00.0 mode switchdev Add a devlink port of subfunction flavour: $ devlink port add pci/0000:06:00.0 flavour pcisf pfnum 0 sfnum 88 Configure mac address of the port function: $ devlink port function set ens2f0npf0sf88 hw_addr 00:00:00:00:88:88 Now activate the function: $ devlink port function set ens2f0npf0sf88 state active Now use the auxiliary device and class devices: $ devlink dev show pci/0000:06:00.0 auxiliary/mlx5_core.sf.4 $ ip link show 127: ens2f0np0: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN mode DEFAULT group default qlen 1000 link/ether 24:8a:07:b3:d1:12 brd ff:ff:ff:ff:ff:ff altname enp6s0f0np0 129: p0sf88: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN mode DEFAULT group default qlen 1000 link/ether 00:00:00:00:88:88 brd ff:ff:ff:ff:ff:ff $ rdma dev show 43: rdmap6s0f0: node_type ca fw 16.29.0550 node_guid 248a:0703:00b3:d112 sys_image_guid 248a:0703:00b3:d112 44: mlx5_0: node_type ca fw 16.29.0550 node_guid 0000:00ff:fe00:8888 sys_image_guid 248a:0703:00b3:d112 After use inactivate the function: $ devlink port function set ens2f0npf0sf88 state inactive Now delete the subfunction port: $ devlink port del ens2f0npf0sf88 [1] https://lore.kernel.org/netdev/20200519092258.GF4655@nanopsycho/ [2] https://marc.info/?l=linux-netdev&m=158555928517777&w=2 ================= * tag 'mlx5-updates-2021-01-13' of git://git.kernel.org/pub/scm/linux/kernel/git/saeed/linux: net/mlx5: Add devlink subfunction port documentation devlink: Extend devlink port documentation for subfunctions devlink: Add devlink port documentation net/mlx5: SF, Port function state change support net/mlx5: SF, Add port add delete functionality net/mlx5: E-switch, Add eswitch helpers for SF vport net/mlx5: E-switch, Prepare eswitch to handle SF vport net/mlx5: SF, Add auxiliary device driver net/mlx5: SF, Add auxiliary device support net/mlx5: Introduce vhca state event notifier devlink: Support get and set state of port function devlink: Support add and delete devlink port devlink: Introduce PCI SF port flavour and port attribute devlink: Prepare code to fill multiple port function attributes ==================== Link: https://lore.kernel.org/r/20210122193658.282884-1-saeed@kernel.org Signed-off-by: Jakub Kicinski <kuba@kernel.org>

2021-01-26net: allow user to set metric on default route learned via Router AdvertisementPraveen Chaudhary
For IPv4, default route is learned via DHCPv4 and user is allowed to change metric using config etc/network/interfaces. But for IPv6, default route can be learned via RA, for which, currently a fixed metric value 1024 is used. Ideally, user should be able to configure metric on default route for IPv6 similar to IPv4.

None of these are actually used in the kernel/userspace interface - there's a userspace component of implementing MRP, and userspace will need to construct certain frames to put on the wire, but there's no reason the kernel should provide the relevant definitions in a UAPI header. In fact, some of those definitions were broken until previous commit, so only keep the few that are actually referenced in the kernel code, and move them to the br_private_mrp.h header.

2021-01-23net: mrp: fix definitions of MRP test packetsRasmus Villemoes
Wireshark says that the MRP test packets cannot be decoded - and the reason for that is that there's a two-byte hole filled with garbage between the "transitions" and "timestamp" members. So Wireshark decodes the two garbage bytes and the top two bytes of the timestamp written by the kernel as the timestamp value (which thus fluctuates wildly), and interprets the lower two bytes of the timestamp as a new (type, length) pair, which is of course broken. Even though this makes the timestamp field in the struct unaligned, it actually makes it end up on a 32 bit boundary in the frame as mandated by the standard, since it is preceded by a two byte TLV header. The struct definitions live under include/uapi/, but they are not really part of any kernel<->userspace API/ABI, so fixing the definitions by adding the packed attribute should not cause any compatibility issues.

2021-01-22sch_htb: Hierarchical QoS hardware offloadMaxim Mikityanskiy
HTB doesn't scale well because of contention on a single lock, and it also consumes CPU. This patch adds support for offloading HTB to hardware that supports hierarchical rate limiting. In the offload mode, HTB passes control commands to the driver using ndo_setup_tc. The driver has to replicate the whole hierarchy of classes and their settings (rate, ceil) in the NIC. Every modification of the HTB tree caused by the admin results in ndo_setup_tc being called. After this setup, the HTB algorithm is done completely in the NIC. An SQ (send queue) is created for every leaf class and attached to the hierarchy, so that the NIC can calculate and obey aggregated rate limits, too. In the future, it can be changed, so that multiple SQs will back a single leaf class. ndo_select_queue is responsible for selecting the right queue that serves the traffic class of each packet. The data path works as follows: a packet is classified by clsact, the driver selects a hardware queue according to its class, and the packet is enqueued into this queue's qdisc. This solution addresses two main problems of scaling HTB: 1. Contention by flow classification. Currently the filters are attached to the HTB instance as follows: # tc filter add dev eth0 parent 1:0 protocol ip flower dst_port 80 classid 1:10 It's possible to move classification to clsact egress hook, which is thread-safe and lock-free: # tc filter add dev eth0 egress protocol ip flower dst_port 80 action skbedit priority 1:10 This way classification still happens in software, but the lock contention is eliminated, and it happens before selecting the TX queue, allowing the driver to translate the class to the corresponding hardware queue in ndo_select_queue. Note that this is already compatible with non-offloaded HTB and doesn't require changes to the kernel nor iproute2. 2. Contention by handling packets. HTB is not multi-queue, it attaches to a whole net device, and handling of all packets takes the same lock. When HTB is offloaded, it registers itself as a multi-queue qdisc, similarly to mq: HTB is attached to the netdev, and each queue has its own qdisc. Some features of HTB may be not supported by some particular hardware, for example, the maximum number of classes may be limited, the granularity of rate and ceil parameters may be different, etc. - so, the offload is not enabled by default, a new parameter is used to enable it: # tc qdisc replace dev eth0 root handle 1: htb offload Signed-off-by: Maxim Mikityanskiy <maximmi@mellanox.com> Reviewed-by: Tariq Toukan <tariqt@nvidia.com> Signed-off-by: Jakub Kicinski <kuba@kernel.org>

2021-01-22devlink: Support get and set state of port functionParav Pandit
devlink port function can be in active or inactive state. Allow users to get and set port function's state. When the port function it activated, its operational state may change after a while when the device is created and driver binds to it. Similarly on deactivation flow. To clearly describe the state of the port function and its device's operational state in the host system, define state and opstate attributes.

2021-01-22devlink: Introduce PCI SF port flavour and port attributeParav Pandit
A PCI sub-function (SF) represents a portion of the device similar to PCI VF. In an eswitch, PCI SF may have port which is normally represented using a representor netdevice. To have better visibility of eswitch port, its association with SF, and its representor netdevice, introduce a PCI SF port flavour. When devlink port flavour is PCI SF, fill up PCI SF attributes of the port. Extend port name creation using PCI PF and SF number scheme on best effort basis, so that vendor drivers can skip defining their own scheme. This is done as cApfNSfM, where A, N and M are controller, PCI PF and PCI SF number respectively. This is similar to existing naming for PCI PF and PCI VF ports. An example view of a PCI SF port: $ devlink port show pci/0000:06:00.0/32768 pci/0000:06:00.0/32768: type eth netdev ens2f0npf0sf88 flavour pcisf controller 0 pfnum 0 sfnum 88 external false splittable false function: hw_addr 00:00:00:00:88:88 state active opstate attached $ devlink port show pci/0000:06:00.0/32768 -jp { "port": { "pci/0000:06:00.0/32768": { "type": "eth", "netdev": "ens2f0npf0sf88", "flavour": "pcisf", "controller": 0, "pfnum": 0, "sfnum": 88, "splittable": false, "function": { "hw_addr": "00:00:00:00:88:88", "state": "active", "opstate": "attached" } } } } Signed-off-by: Parav Pandit <parav@nvidia.com> Reviewed-by: Jiri Pirko <jiri@nvidia.com> Reviewed-by: Vu Pham <vuhuong@nvidia.com> Signed-off-by: Saeed Mahameed <saeedm@nvidia.com>

This comes from an end-user request, where they're running multiple VMs on hosts with bonded interfaces connected to some interest switch topologies, where 802.3ad isn't an option. They're currently running a proprietary solution that effectively achieves load-balancing of VMs and bandwidth utilization improvements with a similar form of transmission algorithm. Basically, each VM has it's own vlan, so it always sends its traffic out the same interface, unless that interface fails. Traffic gets split between the interfaces, maintaining a consistent path, with failover still available if an interface goes down. Unlike bond_eth_hash(), this hash function is using the full source MAC address instead of just the last byte, as there are so few components to the hash, and in the no-vlan case, we would be returning just the last byte of the source MAC as the hash value. It's entirely possible to have two NICs in a bond with the same last byte of their MAC, but not the same MAC, so this adjustment should guarantee distinct hashes in all cases. This has been rudimetarily tested to provide similar results to the proprietary solution it is aiming to replace. A patch for iproute2 is also posted, to properly support the new mode there as well.

2021-01-19RDMA/vmw_pvrdma: Fix network_hdr_type reported in WCBryan Tan
The PVRDMA device HW interface defines network_hdr_type according to an old definition of the internal kernel rdma_network_type enum that has since changed, resulting in the wrong rdma_network_type being reported. Fix this by explicitly defining the enum used by the PVRDMA device and adding a function to convert the pvrdma_network_type to rdma_network_type enum.

Adding support to carry build id data in mmap2 event. The build id data replaces maj/min/ino/ino_generation fields, which are also used to identify map's binary, so it's ok to replace them with build id data: union { struct { u32 maj; u32 min; u64 ino; u64 ino_generation; }; struct { u8 build_id_size; u8 __reserved_1; u16 __reserved_2; u8 build_id[20]; }; }; Replaced maj/min/ino/ino_generation fields give us size of 24 bytes. We use 20 bytes for build id data, 1 byte for size and rest is unused.

2021-01-14bpf: Add instructions for atomic_[cmp]xchgBrendan Jackman
This adds two atomic opcodes, both of which include the BPF_FETCH flag. XCHG without the BPF_FETCH flag would naturally encode atomic_set. This is not supported because it would be of limited value to userspace (it doesn't imply any barriers). CMPXCHG without BPF_FETCH woulud be an atomic compare-and-write. We don't have such an operation in the kernel so it isn't provided to BPF either. There are two significant design decisions made for the CMPXCHG instruction: - To solve the issue that this operation fundamentally has 3 operands, but we only have two register fields. Therefore the operand we compare against (the kernel's API calls it 'old') is hard-coded to be R0. x86 has similar design (and A64 doesn't have this problem). A potential alternative might be to encode the other operand's register number in the immediate field. - The kernel's atomic_cmpxchg returns the old value, while the C11 userspace APIs return a boolean indicating the comparison result. Which should BPF do? A64 returns the old value. x86 returns the old value in the hard-coded register (and also sets a flag). That means return-old-value is easier to JIT, so that's what we use.

In preparation, rename the instruction mode BPF_ATOMIC and start calling the zero immediate BPF_ADD. This is possible (doesn't break existing valid BPF progs) because the immediate field is currently reserved MBZ and BPF_ADD is zero.

2021-01-09bcache: introduce BCH_FEATURE_INCOMPAT_LOG_LARGE_BUCKET_SIZE for large bucketColy Li
When large bucket feature was added, BCH_FEATURE_INCOMPAT_LARGE_BUCKET was introduced into the incompat feature set. It used bucket_size_hi (which was added at the tail of struct cache_sb_disk) to extend current 16bit bucket size to 32bit with existing bucket_size in struct cache_sb_disk. This is not a good idea, there are two obvious problems, - Bucket size is always value power of 2, if store log2(bucket size) in existing bucket_size of struct cache_sb_disk, it is unnecessary to add bucket_size_hi. - Macro csum_set() assumes d[SB_JOURNAL_BUCKETS] is the last member in struct cache_sb_disk, bucket_size_hi was added after d[] which makes csum_set calculate an unexpected super block checksum. To fix the above problems, this patch introduces a new incompat feature bit BCH_FEATURE_INCOMPAT_LOG_LARGE_BUCKET_SIZE, when this bit is set, it means bucket_size in struct cache_sb_disk stores the order of power-of-2 bucket size value. When user specifies a bucket size larger than 32768 sectors, BCH_FEATURE_INCOMPAT_LOG_LARGE_BUCKET_SIZE will be set to incompat feature set, and bucket_size stores log2(bucket size) more than store the real bucket size value. The obsoleted BCH_FEATURE_INCOMPAT_LARGE_BUCKET won't be used anymore, it is renamed to BCH_FEATURE_INCOMPAT_OBSO_LARGE_BUCKET and still only recognized by kernel driver for legacy compatible purpose. The previous bucket_size_hi is renmaed to obso_bucket_size_hi in struct cache_sb_disk and not used in bcache-tools anymore. For cache device created with BCH_FEATURE_INCOMPAT_LARGE_BUCKET feature, bcache-tools and kernel driver still recognize the feature string and display it as "obso_large_bucket". With this change, the unnecessary extra space extend of bcache on-disk super block can be avoided, and csum_set() may generate expected check sum as well.

2021-01-07KVM: SVM: Add support for booting APs in an SEV-ES guestTom Lendacky
Typically under KVM, an AP is booted using the INIT-SIPI-SIPI sequence, where the guest vCPU register state is updated and then the vCPU is VMRUN to begin execution of the AP. For an SEV-ES guest, this won't work because the guest register state is encrypted. Following the GHCB specification, the hypervisor must not alter the guest register state, so KVM must track an AP/vCPU boot. Should the guest want to park the AP, it must use the AP Reset Hold exit event in place of, for example, a HLT loop. First AP boot (first INIT-SIPI-SIPI sequence): Execute the AP (vCPU) as it was initialized and measured by the SEV-ES support. It is up to the guest to transfer control of the AP to the proper location. Subsequent AP boot: KVM will expect to receive an AP Reset Hold exit event indicating that the vCPU is being parked and will require an INIT-SIPI-SIPI sequence to awaken it. When the AP Reset Hold exit event is received, KVM will place the vCPU into a simulated HLT mode. Upon receiving the INIT-SIPI-SIPI sequence, KVM will make the vCPU runnable. It is again up to the guest to then transfer control of the AP to the proper location. To differentiate between an actual HLT and an AP Reset Hold, a new MP state is introduced, KVM_MP_STATE_AP_RESET_HOLD, which the vCPU is placed in upon receiving the AP Reset Hold exit event. Additionally, to communicate the AP Reset Hold exit event up to userspace (if needed), a new exit reason is introduced, KVM_EXIT_AP_RESET_HOLD. A new x86 ops function is introduced, vcpu_deliver_sipi_vector, in order to accomplish AP booting. For VMX, vcpu_deliver_sipi_vector is set to the original SIPI delivery function, kvm_vcpu_deliver_sipi_vector(). SVM adds a new function that, for non SEV-ES guests, invokes the original SIPI delivery function, kvm_vcpu_deliver_sipi_vector(), but for SEV-ES guests, implements the logic above.

The set flag NFT_SET_EXPR provides a hint to the kernel that userspace supports for multiple expressions per set element. In the same direction, NFT_DYNSET_F_EXPR specifies that dynset expression defines multiple expressions per set element. This allows new userspace software with old kernels to bail out with EOPNOTSUPP. This update is similar to ef516e8625dd ("netfilter: nf_tables: reintroduce the NFT_SET_CONCAT flag"). The NFT_SET_EXPR flag needs to be set on when the NFTA_SET_EXPRESSIONS attribute is specified.

git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio Pull GPIO updates from Linus Walleij: "This is the bulk of the GPIO changes for the v5.11 kernel cycle: Core changes: - Retired the old set-up function for GPIO IRQ chips. All chips now use the template struct gpio_irq_chip and pass that to the core to be set up alongside the gpio_chip. We can finally get rid of the old cruft. - Some refactoring and clean up of the core code. - Support edge event timestamps to be stamped using REALTIME (wall clock) timestamps. We have found solid use cases for this, so we support it. New drivers: - MStar MSC313 GPIO driver. - HiSilicon GPIO driver. Driver improvements: - The PCA953x driver now also supports the NXP PCAL9554B/C chips. - The mockup driver can now be probed from the device tree which is pretty useful for virtual prototyping of devices. - The Rcar driver now supports .get_multiple() - The MXC driver dropped some legacy and became a pure device tree client. - The Exar driver was moved over to the IDA interface for enumerating, and also switched over to using regmap for register access" * tag 'gpio-v5.11-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio: (87 commits) MAINTAINERS: Remove reference to non-existing file gpio: hisi: Do not require ACPI for COMPILE_TEST MAINTAINERS: Add maintainer for HiSilicon GPIO driver gpio: gpio-hisi: Add HiSilicon GPIO support gpio: cs5535: Simplify the return expression of cs5535_gpio_probe() gpiolib: irq hooks: fix recursion in gpiochip_irq_unmask dt-bindings: mt7621-gpio: convert bindings to YAML format gpiolib: cdev: Flag invalid GPIOs as used gpio: put virtual gpio device into their own submenu drivers: gpio: amd8111: use SPDX-License-Identifier drivers: gpio: amd8111: prefer dev_err()/dev_info() over raw printk drivers: gpio: bt8xx: prefer dev_err()/dev_warn() over of raw printk gpio: Add TODO item for debugfs interface gpio: just plain warning when nonexisting gpio requested tools: gpio: add option to report wall-clock time to gpio-event-mon tools: gpio: add support for reporting realtime event clock to lsgpio gpiolib: cdev: allow edge event timestamps to be configured as REALTIME gpio: msc313: MStar MSC313 GPIO driver dt-bindings: gpio: Binding for MStar MSC313 GPIO controller dt-bindings: gpio: Add a binding header for the MSC313 GPIO driver ...
