RDMA/nldev: Added configuration of RDMA dynamic interrupt moderation to netlink

2019-07-08T19:37:22+00:00

Added parameter in ib_device for enabling dynamic interrupt moderation so that it can be configured in userspace using rdma tool. In order to set adaptive-moderation for an ib device the command is: rdma dev set [DEV] adaptive-moderation [on|off] Please set on/off. rdma dev show 0: mlx5_0: node_type ca fw 16.26.0055 node_guid 248a:0703:00a5:29d0 sys_image_guid 248a:0703:00a5:29d0 adaptive-moderation on rdma resource show cq dev mlx5_0 cqn 0 cqe 1023 users 4 poll-ctx UNBOUND_WORKQUEUE adaptive-moderation off comm [ib_core] Signed-off-by: Yamin Friedman Reviewed-by: Sagi Grimberg Signed-off-by: Leon Romanovsky Signed-off-by: Jason Gunthorpe

RDMA/nldev: Allow counter manual mode configration through RDMA netlink

Provide an option to allow users to manually bind a qp with a counter through RDMA netlink. Limit it to users with ADMIN capability only. Signed-off-by: Mark Zhang Reviewed-by: Majd Dibbiny Signed-off-by: Leon Romanovsky Signed-off-by: Jason Gunthorpe

RDMA/counter: Allow manual mode configuration support

2019-07-05T13:22:55+00:00

In manual mode a QP is bound to a counter manually. If counter is not specified then a new one will be allocated. Manual mode is enabled when user binds a QP, and disabled when the last manually bound QP is unbound. When auto-mode is turned off and there are counters left, manual mode is enabled so that the user is able to access these counters.

RDMA/netlink: Audit policy settings for netlink attributes

2019-06-25T19:26:54+00:00

For all string attributes for which we don't currently accept the element as input, we only use it as output, set the string length to RDMA_NLDEV_ATTR_EMPTY_STRING which is defined as 1. That way we will only accept a null string for that element. This will prevent someone from writing a new input routine that uses the element without also updating the policy to have a valid value. Also while there, make sure the existing entries that are valid have the correct policy, if not, correct the policy. Remove unnecessary checks for nla_strlcpy() overflow once the policy has been set correctly. Signed-off-by: Doug Ledford Signed-off-by: Jason Gunthorpe

RDMA: Report available cdevs through RDMA_NLDEV_CMD_GET_CHARDEV

2019-06-19T02:44:08+00:00

Update the struct ib_client for all modules exporting cdevs related to the ibdevice to also implement RDMA_NLDEV_CMD_GET_CHARDEV. All cdevs are now autoloadable and discoverable by userspace over netlink instead of relying on sysfs. uverbs also exposes the DRIVER_ID for drivers that are able to support driver id binding in rdma-core.

RDMA: Add NLDEV_GET_CHARDEV to allow char dev discovery and autoload

2019-06-19T02:41:05+00:00

Allow userspace to issue a netlink query against the ib_device for something like "uverbs" and get back the char dev name, inode major/minor, and interface ABI information for "uverbs0". Since we are now in netlink this can also trigger a module autoload to make the uverbs device come into existence. Largely this will let us replace searching and reading inside sysfs to setup devices, and provides an alternative (using driver_id) to device name based provider binding for things like rxe.
