2022-03-18IB/iser: Fix error flow in case of registration failureMax Gurtovoy1-3/+11
During READ/WRITE preparation, in case of failure in memory registration using iser_reg_mem_fastreg we must unmap previously mapped iser task.

2022-03-16RDMA/rxe: Replace red-black trees by xarraysBob Pearson6-280/+85
Currently the rxe driver uses red-black trees to add indices to the rxe object pools. Linux xarrays provide a better way to implement the same functionality for indices. This patch replaces red-black trees by xarrays for pool objects. Since xarrays already have a spinlock use that in place of the pool rwlock. Make sure that all changes in the xarray(index) and kref(ref counnt) occur atomically.

There is only one remaining object type that allocates its own memory, that is mr. So the sense of RXE_POOL_NO_ALLOC is changed to RXE_POOL_ALLOC. Add checks to rxe_alloc() and rxe_add_to_pool() to make sure the correct call is used for the setting of this flag.

2022-03-15RDMA/rxe: Replace mr by rkey in responder resourcesBob Pearson3-47/+87
Currently rxe saves a copy of MR in responder resources for RDMA reads. Since the responder resources are never freed just over written if more are needed this MR may not have a reference freed until the QP is destroyed. This patch uses the rkey instead of the MR and on subsequent packets of a multipacket read reply message it looks up the MR from the rkey for each packet. This makes it possible for a user to deregister an MR or unbind a MW on the fly and get correct behaviour.

2022-03-15RDMA/rxe: Fix ref error in rxe_av.cBob Pearson5-35/+63
The commit referenced below can take a reference to the AH which is never dropped. This only happens in the UD request path. This patch optionally passes that AH back to the caller so that it can hold the reference while the AV is being accessed and then drop it. Code to do this is added to rxe_req.c. The AV is also passed to rxe_prepare in rxe_net.c as an optimization.

Fix this by finding the real netdev and processing the notifications for vlan netdevs. Fixes: 915cc7ac0f8e ("RDMA/irdma: Add miscellaneous utility definitions") Link: https://lore.kernel.org/r/20220225163211.127-2-shiraz.saleem@intel.com Signed-off-by: Mustafa Ismail <mustafa.ismail@intel.com> Signed-off-by: Shiraz Saleem <shiraz.saleem@intel.com> Reviewed-by: Leon Romanovsky <leonro@nvidia.com> Signed-off-by: Jason Gunthorpe <jgg@nvidia.com>

The function irdma_create_mg_ctx always returns 0, so make it void and delete the return value check.

The union irdma_sockaddr is used frequently. So move it to the header file. Link: https://lore.kernel.org/r/20220223024252.3873736-4-yanjun.zhu@linux.dev Signed-off-by: Zhu Yanjun <yanjun.zhu@linux.dev> Signed-off-by: Jason Gunthorpe <jgg@nvidia.com>
2022-02-23RDMA/irdma: Remove the unnecessary variable saddrZhu Yanjun2-2/+0
Firstly the variable saddr was to check the type of a network. Now the variable net_type is used to do the same work. So it is removed.

2022-02-23RDMA/irdma: Remove excess error variablesShiraz Saleem2-76/+28
As irdma_status_code is replaced with an int, there is no need for two variables to hold error codes. Remove the excess variable in functions where this occurs. Also, remove any redundant initializations which are no longer needed.

2022-02-23RDMA/mlx5: Reorder calls to pcie_relaxed_ordering_enabled()Aharon Landau1-7/+7
The mkc is the key for the mkey cache, hence, created in each attempt to get a cache mkey, while pcie_relaxed_ordering_enabled() is called during the setting of the mkc, but used only for cases where IB_ACCESS_RELAXED_ORDERING is set. pcie_relaxed_ordering_enabled() is an expensive call (26 us). Reorder the code so the driver will call it only when it is needed.

2022-02-23RDMA/mlx5: Store ndescs instead of the translation table sizeAharon Landau3-10/+25
Currently, ent->xlt stores the translation table size. This data should not be stored in the cache entry but be written directly to the mailbox. Store ndescs instead, and deduce the translation table size from it according to the access mode.
