2019-02-19RDMA/rxe: Use ib_device_get_by_netdev() instead of open codingJason Gunthorpe4-47/+38
The core API handles the locking correctly and is faster if there are multiple devices. Signed-off-by: Jason Gunthorpe <jgg@mellanox.com>
2019-02-19RDMA/device: Add ib_device_get_by_netdev()Jason Gunthorpe1-12/+107
Several drivers need to find the ib_device from a given netdev. rxe needs this at speed in an unsleepable context, so choose to implement the translation using a RCU safe hash table. The hash table can have a many to one mapping. This is intended to support some future case where multiple IB drivers (ie iWarp and RoCE) connect to the same netdevs. driver_ids will need to be different to support this. In the process this makes the struct ib_device and ib_port_data RCU safe by deferring their kfrees. Signed-off-by: Jason Gunthorpe <jgg@mellanox.com>
2019-02-19RDMA/device: Add ib_device_set_netdev() as an alternative to get_netdevJason Gunthorpe5-38/+164
The associated netdev should not actually be very dynamic, so for most drivers there is no reason for a callback like this. Provide an API to inform the core code about the net dev affiliation and use a core maintained data structure instead. This allows the core code to be more aware of the ndev relationship which will allow some new APIs based around this. This also uses locking that makes some kind of sense, many drivers had a confusing RCU lock, or missing locking which isn't right. Signed-off-by: Jason Gunthorpe <jgg@mellanox.com>
2019-02-19RDMA/cache: Move the cache per-port data into the main ib_port_dataJason Gunthorpe1-58/+31
Like the other cases there no real reason to have another array just for the cache. This larger conversion gets its own patch. Signed-off-by: Jason Gunthorpe <jgg@mellanox.com>
2019-02-19RDMA/device: Consolidate ib_device per_port data into one placeJason Gunthorpe3-63/+35
There is no reason to have three allocations of per-port data. Combine them together and make the lifetime for all the per-port data match the struct ib_device. Following patches will require more port-specific data, now there is a good place to put it. Signed-off-by: Jason Gunthorpe <jgg@mellanox.com>
2019-02-19RDMA: Add and use rdma_for_each_portJason Gunthorpe10-46/+42
We have many loops iterating over all of the end port numbers on a struct ib_device, simplify them with a for_each helper. Reviewed-by: Parav Pandit <parav@mellanox.com> Signed-off-by: Jason Gunthorpe <jgg@mellanox.com>
2019-02-19RDMA/nldev: Don't expose number of not-visible entriesLeon Romanovsky1-5/+2

2019-02-19RDMA/nldev: Connect QP number to .doit callbackLeon Romanovsky2-1/+11
This patch adds ability to query specific QP based on its LQPN (local QPN), which is assigned by HW and needs special treatment while inserting into restrack DB. Signed-off-by: Leon Romanovsky <leonro@mellanox.com> Signed-off-by: Jason Gunthorpe <jgg@mellanox.com>
2019-02-19RDMA/nldev: Provide parent IDs for PD, MR and QP objectsLeon Romanovsky1-0/+18

2019-02-19RDMA/nldev: Share with user-space object IDsLeon Romanovsky1-0/+20
Give to the user space tools unique identifier for PD, MR, CQ and CM_ID objects, so they can be able to query on them with .doit callbacks. QP .doit is not supported yet, till all drivers will be updated to provide their LQPN to be equal to their restrack ID.

2019-02-19RDMA/restrack: Prepare restrack_root to addition of extra fields per-typeLeon Romanovsky3-78/+43
As a preparation to extension of rdma_restrack_root to provide software IDs, which will be per-type too. We convert the rdma_restrack_root from struct with arrays to array of structs. Such conversion allows us to drop rwsem lock in favour of internal XArray lock. Signed-off-by: Leon Romanovsky <leonro@mellanox.com> Signed-off-by: Jason Gunthorpe <jgg@mellanox.com>

2019-02-18RDMA/restrack: Convert internal DB from hash to XArrayLeon Romanovsky2-38/+78
The additions of .doit callbacks posses new access pattern to the resource entries by some user visible index. Back then, the legacy DB was implemented as hash because per-index access wasn't needed and XArray wasn't accepted yet. Acceptance of XArray together with per-index access requires the refresh of DB implementation. Signed-off-by: Leon Romanovsky <leonro@mellanox.com> Signed-off-by: Jason Gunthorpe <jgg@mellanox.com>
