RDMA: Add EFA related definitions

2019-05-06T16:47:50+00:00

Add EFA driver ID to the IOCTL interface uapi. This patch also adds unspecified node/transport type that will be used by EFA (usnic is left unchanged as it's already part of our ABI).

RDMA/verbs: Add a DMA iterator to return aligned contiguous memory blocks

2019-05-06T16:08:11+00:00

This helper iterates over a DMA-mapped SGL and returns contiguous memory blocks aligned to a HW supported page size. Suggested-by: Jason Gunthorpe Signed-off-by: Shiraz Saleem Signed-off-by: Jason Gunthorpe

IB/core: Set qp->real_qp before it may be accessed

2019-05-03T13:17:45+00:00

real_qp should be initialized before ib_destroy_qp() is called. ib_destroy_qp() may be called in the error flow if ib_create_qp_security() failed. Signed-off-by: Artemy Kovalyov Signed-off-by: Leon Romanovsky Signed-off-by: Jason Gunthorpe

RDMA: Handle SRQ allocations by IB/core

2019-04-08T16:05:25+00:00

Convert SRQ allocation from drivers to be in the IB/core Signed-off-by: Leon Romanovsky Signed-off-by: Jason Gunthorpe

RDMA: Handle AH allocations by IB/core

2019-04-08T16:05:25+00:00

Simplify drivers by ensuring lifetime of ib_ah object. The changes in .create_ah() go hand in hand with relevant update in .destroy_ah(). We will use this opportunity and convert .destroy_ah() to don't fail, as it was suggested a long time ago, because there is nothing to do in case of failure during destroy.

IB: Pass only ib_udata in function prototypes

2019-04-01T18:00:47+00:00

Now when ib_udata is passed to all the driver's object create/destroy APIs the ib_udata will carry the ib_ucontext for every user command. There is no need to also pass the ib_ucontext via the functions prototypes. Make ib_udata the only argument psssed. Signed-off-by: Shamir Rabinovitch Signed-off-by: Jason Gunthorpe

IB: Pass uverbs_attr_bundle down ib_x destroy path

2019-04-01T17:57:35+00:00

The uverbs_attr_bundle with the ucontext is sent down to the drivers ib_x destroy path as ib_udata. The next patch will use the ib_udata to free the drivers destroy path from the dependency in 'uobject->context' as we already did for the create path.

RDMA/device: Add ib_device_set_netdev() as an alternative to get_netdev

2019-02-20T03:52:18+00:00

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

RDMA: Handle PD allocations by IB/core

2019-02-08T23:51:04+00:00

The PD allocations in IB/core allows us to simplify drivers and their error flows in their .alloc_pd() paths. The changes in .alloc_pd() go hand in had with relevant update in .dealloc_pd(). We will use this opportunity and convert .dealloc_pd() to don't fail, as it was suggested a long time ago, failures are not happening as we have never seen a WARN_ON print.

IB/core: Destroy QP if XRC QP fails

2019-01-24T16:22:30+00:00

The open-coded variant missed destroy of SELinux created QP, reuse already existing ib_detroy_qp() call and use this opportunity to clean ib_create_qp() from double prints and unclear exit paths.
