2021-06-12rtnetlink: add IFLA_PARENT_[DEV|DEV_BUS]_NAMEJohannes Berg-0/+7
In some cases, for example in the upcoming WWAN framework changes, there's no natural "parent netdev", so sometimes dummy netdevs are created or similar. IFLA_PARENT_DEV_NAME is a new attribute intended to contain a device (sysfs, struct device) name that can be used instead when creating a new netdev, if the rtnetlink family implements it. As suggested by Parav Pandit, we also introduce IFLA_PARENT_DEV_BUS_NAME attribute in order to uniquely identify a device on the system (with bus/name pair). ip-link(8) support for the generic parent device attributes will help us avoid code duplication, so no other link type will require a custom code to handle the parent name attribute. E.g. the WWAN interface creation command will looks like this: $ ip link add wwan0-1 parent-dev wwan0 type wwan channel-id 1 So, some future subsystem (or driver) FOO will have an interface creation command that looks like this: $ ip link add foo1-3 parent-dev foo1 type foo bar-id 3 baz-type Y Below is an example of dumping link info of a random device with these new attributes: $ ip --details link show wlp0s20f3 4: wlp0s20f3: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP mode DORMANT group default qlen 1000 ... parent_bus pci parent_dev 0000:00:14.3 Co-developed-by: Sergey Ryazanov <ryazanov.s.a@gmail.com> Signed-off-by: Sergey Ryazanov <ryazanov.s.a@gmail.com> Co-developed-by: Loic Poulain <loic.poulain@linaro.org> Signed-off-by: Loic Poulain <loic.poulain@linaro.org> Suggested-by: Sergey Ryazanov <ryazanov.s.a@gmail.com> Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: David S.

2021-06-10io_uring: change registration/upd/rsrc tagging ABIPavel Begunkov-9/+9
There are ABI moments about recently added rsrc registration/update and tagging that might become a nuisance in the future. First, IORING_REGISTER_RSRC[_UPD] hide different types of resources under it, so breaks fine control over them by restrictions. It works for now, but once those are wanted under restrictions it would require a rework. It was also inconvenient trying to fit a new resource not supporting all the features (e.g. dynamic update) into the interface, so better to return to IORING_REGISTER_* top level dispatching. Second, register/update were considered to accept a type of resource, however that's not a good idea because there might be several ways of registration of a single resource type, e.g. we may want to add non-contig buffers or anything more exquisite as dma mapped memory. So, remove IORING_RSRC_[FILE,BUFFER] out of the ABI, and place them internally for now to limit changes.

2021-06-07quota: Change quotactl_path() systcall to an fd-based oneJan Kara-2/+2
Some users have pointed out that path-based syscalls are problematic in some environments and at least directory fd argument and possibly also resolve flags are desirable for such syscalls. Rather than reimplementing all details of pathname lookup and following where it may eventually evolve, let's go for full file descriptor based syscall similar to how ioctl(2) works since the beginning. Managing of quotas isn't performance sensitive so the extra overhead of open does not matter and we are able to consume O_PATH descriptors as well which makes open cheap anyway. Also for frequent operations (such as retrieving usage information for all users) we can reuse single fd and in fact get even better performance as well as avoiding races with possible remounts etc. Tested-by: Sascha Hauer <s.hauer@pengutronix.de> Acked-by: Christian Brauner <christian.brauner@ubuntu.com> Reviewed-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Jan Kara <jack@suse.cz>

2021-06-04drm/panfrost: Add AFBC_FEATURES parameterAlyssa Rosenzweig-0/+1
The value of the AFBC_FEATURES register is required by userspace to determine AFBC support on Bifrost. A user on our IRC channel (#panfrost) reported a workload that raised a fault on one system's Mali G31 but worked flawlessly with another system's Mali G31. We determined the cause to be missing AFBC support on one vendor's Mali implementation -- it turns out AFBC is optional on Bifrost! Whether AFBC is supported or not is exposed in the AFBC_FEATURES register on Bifrost, which reads back as 0 on Midgard. A zero value indicates AFBC is fully supported, provided the architecture itself supports AFBC, allowing backwards-compatibility with Midgard. Bits 0 and 15 indicate that AFBC support is absent for texturing and rendering respectively. The user experiencing the fault reports that AFBC_FEATURES reads back 0x10001 on their system, confirming the architectural lack of AFBC. Userspace needs this parameter to know to disable AFBC on that chip, and perhaps others. v2: Fix typo from copy-paste fail. v3: Bump the UABI version. This commit was cherry-picked from another series so chalking this up to a rebase fail.

Shiraz Saleem says: ==================== Add Intel Ethernet Protocol Driver for RDMA (irdma) The following patch series introduces a unified Intel Ethernet Protocol Driver for RDMA (irdma) for the X722 iWARP device and a new E810 device which supports iWARP and RoCEv2. The irdma module replaces the legacy i40iw module for X722 and extends the ABI already defined for i40iw. It is backward compatible with legacy X722 rdma-core provider (libi40iw). X722 and E810 are PCI network devices that are RDMA capable. The RDMA block of this parent device is represented via an auxiliary device exported to 'irdma' using the core auxiliary bus infrastructure recently added for 5.11 kernel. The parent PCI netdev drivers 'i40e' and 'ice' register auxiliary RDMA devices with private data/ops encapsulated that bind to auxiliary drivers registered in irdma module. Currently, default is RoCEv2 for E810.

2021-06-02devlink: Allow setting parent node of rate objectsDmytro Linkin-0/+1
Refactor DEVLINK_CMD_RATE_{GET|SET} command handlers to support setting a node as a parent for another rate object (leaf or node) by means of new attribute DEVLINK_ATTR_RATE_PARENT_NODE_NAME. Extend devlink ops with new callbacks rate_{leaf|node}_parent_set() to set node as a parent for rate object to allow supporting drivers to implement rate grouping through devlink. Driver implementations are allowed to support leafs or node children only. Invoking callback with NULL as parent should be threated by the driver as unset parent action. Extend rate object struct with reference counter to disallow deleting a node with any child pointing to it. User should unset parent for the child explicitly. Example: $ devlink port function rate add netdevsim/netdevsim10/group1 $ devlink port function rate add netdevsim/netdevsim10/group2 $ devlink port function rate set netdevsim/netdevsim10/group1 parent group2 $ devlink port function rate show netdevsim/netdevsim10/group1 netdevsim/netdevsim10/group1: type node parent group2 $ devlink port function rate set netdevsim/netdevsim10/group1 noparent Co-developed-by: Vlad Buslov <vladbu@nvidia.com> Signed-off-by: Vlad Buslov <vladbu@nvidia.com> Signed-off-by: Dmytro Linkin <dlinkin@nvidia.com> Reviewed-by: Jiri Pirko <jiri@nvidia.com> Signed-off-by: David S.

2021-06-02devlink: Introduce rate nodesDmytro Linkin-0/+3
Implement support for DEVLINK_CMD_RATE_{NEW|DEL} commands that are used to create and delete devlink rate nodes. Add new attribute DEVLINK_ATTR_RATE_NODE_NAME that specify node name string. The node name is an alphanumeric identifier. No valid node name can be a devlink port index, eg. decimal number. Extend devlink ops with new callbacks rate_node_{new|del}() and rate_node_tx_{share|max}_set() to allow supporting drivers to implement ports rate grouping and setting tx rate of rate nodes through devlink. Expose devlink_rate_nodes_destroy() function to allow vendor driver do proper cleanup of internally allocated resources for the nodes if the driver goes down or due to any other reasons which requires nodes to be destroyed. Disallow moving device from switchdev to legacy mode if any node exists on that device. User must explicitly delete nodes before switching mode. Example: $ devlink port function rate add netdevsim/netdevsim10/group1 $ devlink port function rate set netdevsim/netdevsim10/group1 \ tx_share 10mbit tx_max 100mbit Add + set command can be combined: $ devlink port function rate add netdevsim/netdevsim10/group1 \ tx_share 10mbit tx_max 100mbit $ devlink port function rate show netdevsim/netdevsim10/group1 netdevsim/netdevsim10/group1: type node tx_share 10mbit tx_max 100mbit $ devlink port function rate del netdevsim/netdevsim10/group1 Co-developed-by: Vlad Buslov <vladbu@nvidia.com> Signed-off-by: Vlad Buslov <vladbu@nvidia.com> Signed-off-by: Dmytro Linkin <dlinkin@nvidia.com> Reviewed-by: Jiri Pirko <jiri@nvidia.com> Signed-off-by: David S.

Implement support for DEVLINK_CMD_RATE_SET command with new attributes DEVLINK_ATTR_RATE_TX_{SHARE|MAX} that are used to set devlink rate shared/max tx rate values. Extend devlink ops with new callbacks rate_leaf_tx_{share|max}_set() to allow supporting drivers to implement rate control through devlink. New attributes are optional. Driver implementations are allowed to support either or both of them. Shared rate example: $ devlink port function rate set netdevsim/netdevsim10/0 tx_share 10mbit $ devlink port function rate show netdevsim/netdevsim10/0 netdevsim/netdevsim10/0: type leaf tx_share 10mbit Max rate example: $ devlink port function rate set netdevsim/netdevsim10/0 tx_max 100mbit $ devlink port function rate show netdevsim/netdevsim10/0 netdevsim/netdevsim10/0: type leaf tx_max 100mbit Co-developed-by: Vlad Buslov <vladbu@nvidia.com> Signed-off-by: Vlad Buslov <vladbu@nvidia.com> Signed-off-by: Dmytro Linkin <dlinkin@nvidia.com> Reviewed-by: Jiri Pirko <jiri@nvidia.com> Signed-off-by: David S.

Adding support for processing of MAPv5 downlink packets. It involves parsing the Mapv5 packet and checking the csum header to know whether the hardware has validated the checksum and is valid or not. Based on the checksum valid bit the corresponding stats are incremented and skb->ip_summed is marked either CHECKSUM_UNNECESSARY or left as CHEKSUM_NONE to let network stack revalidate the checksum and update the respective snmp stats. Current MAPV1 header has been modified, the reserved field in the Mapv1 header is now used for next header indication.
