2021-12-29net: Don't include filter.h from net/sock.hJakub Kicinski1-0/+1
sock.h is pretty heavily used (5k objects rebuilt on x86 after it's touched). We can drop the include of filter.h from it and add a forward declaration of struct sk_filter instead. This decreases the number of rebuilt objects when bpf.h is touched from ~5k to ~1k. There's a lot of missing includes this was masking. Primarily in networking tho, this time.

2021-08-24RDMA: Use the sg_table directly and remove the opencoded version from umemMaor Gottlieb1-1/+2
This allows using the normal sg_table APIs and makes all the code cleaner. Remove sgt, nents and nmapd from ib_umem.

2021-06-03RDMA/mlx5: Use different doorbell memory for different processesMark Zhang1-1/+6
In a fork scenario, the parent and child can have same virtual address and also share the uverbs fd. That causes to the list_for_each_entry search return same doorbell physical page for all processes, even though that page has been COW' or copied. This patch takes the mm_struct into consideration during search, to make sure that VA's belonging to different processes are not intermixed. Resolves the malfunction of uverbs after fork in some specific cases.

2020-01-16IB: Allow calls to ib_umem_get from kernel ULPsMoni Shoua1-1/+2
So far the assumption was that ib_umem_get() and ib_umem_odp_get() are called from flows that start in UVERBS and therefore has a user context. This assumption restricts flows that are initiated by ULPs and need the service that ib_umem_get() provides. This patch changes ib_umem_get() and ib_umem_odp_get() to get IB device directly by relying on the fact that both UVERBS and ULPs sets that field correctly.

2019-01-10IB/{core,hw}: Have ib_umem_get extract the ib_ucontext from ib_udataJason Gunthorpe1-3/+3
ib_umem_get() can only be called in a method callback, which always has a udata parameter. This allows ib_umem_get() to derive the ucontext pointer directly from the udata without requiring the drivers to find it in some way or another.

2014-03-04IB: Refactor umem to use linear SG tableYishai Hadas1-3/+1
This patch refactors the IB core umem code and vendor drivers to use a linear (chained) SG table instead of chunk list. With this change the relevant code becomes clearer—no need for nested loops to build and use umem.

2013-07-08mlx5: Add driver for Mellanox Connect-IB adaptersEli Cohen1-0/+100
The driver is comprised of two kernel modules: mlx5_ib and mlx5_core. This partitioning resembles what we have for mlx4, except that mlx5_ib is the pci device driver and not mlx5_core. mlx5_core is essentially a library that provides general functionality that is intended to be used by other Mellanox devices that will be introduced in the future. mlx5_ib has a similar role as any hardware device under drivers/infiniband/hw.
