2017-08-24IB/core: Avoid accessing non-allocated memory when inferring port typeNoa Osherovich1-0/+1
Commit 44c58487d51a ("IB/core: Define 'ib' and 'roce' rdma_ah_attr types") introduced the concept of type in ah_attr: * During ib_register_device, each port is checked for its type which is stored in ib_device's port_immutable array. * During uverbs' modify_qp, the type is inferred using the port number in ib_uverbs_qp_dest struct (address vector) by accessing the relevant port_immutable array and the type is passed on to providers. IB spec (version 1.3) enforces a valid port value only in Reset to Init. During Init to RTR, the address vector must be valid but port number is not mentioned as a field in the address vector, so its value is not validated, which leads to accesses to a non-allocated memory when inferring the port type. Save the real port number in ib_qp during modify to Init (when the comp_mask indicates that the port number is valid) and use this value to infer the port type. Avoid copying the address vector fields if the matching bit is not set in the attr_mask. Address vector can't be modified before the port, so no valid flow is affected.

2017-08-18PCI/IB: add support for pci driver attribute groupsGreg Kroah-Hartman1-0/+1
Some drivers (specifically the nes IB driver), want to create a lot of sysfs driver attributes. Instead of open-coding the creation and removal of these files (and getting it wrong btw), it's a better idea to let the driver core handle all of this logic for us. So add a new field to the pci driver structure, **groups, that allows pci drivers to specify an attribute group list it wishes to have created when it is registered with the driver core. Big bonus is now the driver doesn't race with userspace when the sysfs files are created vs. when the kobject is announced, so any script/tool that actually wanted to use these files will not have to poll waiting for them to show up.

There is a need to forward FW version to user space application through RDMA netlink. In order to make it safe, there is need to declare nla_policy and limit the size of FW string. The new define IB_FW_VERSION_NAME_MAX will limit the size of FW version string. That define was chosen to be equal to ETHTOOL_FWVERS_LEN, because many drivers anyway are limited by that value indirectly.

2017-08-10RDMA/netlink: Add netlink device definitions to UAPILeon Romanovsky1-1/+38
Introduce new defines to rdma_netlink.h, so the RDMA configuration tool will be able to communicate with RDMA subsystem by using the shared defines. The addition of new client (NLDEV) revealed the fact that we exposed by mistake the RDMA_NL_I40IW define which is not backed by any RDMA netlink by now and it won't be exposed in the future too. So this patch reuses the value and deletes the old defines. The NLDEV operates with objects. The struct ib_device has two straightforward objects: device itself and ports of that device. This brings us to propose the following commands to work on those objects: * RDMA_NLDEV_CMD_{GET,SET,NEW,DEL} - works on ib_device itself * RDMA_NLDEV_CMD_PORT_{GET,SET,NEW,DEL} - works on ports of specific ib_device Those commands receive/return the device index (RDMA_NLDEV_ATTR_DEV_INDEX) and port index (RDMA_NLDEV_ATTR_PORT_INDEX). For device object accesses, the RDMA_NLDEV_ATTR_PORT_INDEX will return the maximum number of ports for specific ib_device and for port access the actual port index. The port index starts from 1 to follow RDMA/core internal semantics and the sysfs exposed knobs.

2017-08-10RDMA/netlink: Remove netlink clients infrastructureLeon Romanovsky1-9/+4
RDMA netlink has a complicated infrastructure for dynamically registering and de-registering netlink clients to the NETLINK_RDMA group. The complicated portion of this code is not widely used because 2 of the 3 current clients are statically compiled together with netlink.c. The infrastructure, therefore, is deemed overkill. Refactor the code to eliminate the dynamically added clients. Now all clients are pre-registered in a client array at compile time, and at run time they merely check-in with the infrastructure to pass their callback table for inclusion in the pre-sized client array. This also allows for future cleanups and removal of unneeded code in the iwcm* netlink handler.
