uaccess: remove CONFIG_SET_FS

2022-02-25T08:36:06Z

There are no remaining callers of set_fs(), so CONFIG_SET_FS can be removed globally, along with the thread_info field and any references to it. This turns access_ok() into a cheaper check against TASK_SIZE_MAX. As CONFIG_SET_FS is now gone, drop all remaining references to set_fs()/get_fs(), mm_segment_t, user_addr_max() and uaccess_kernel(). Acked-by: Sam Ravnborg # for sparc32 changes Acked-by: "Eric W.

RDMA/core: Calculate UDP source port based on flow label or lqpn/rqpn

2022-01-07T23:34:01Z

Calculate and set UDP source port based on the flow label. If flow label is not defined in GRH then calculate it based on lqpn/rqpn. Link: https://lore.kernel.org/r/20220106180359.2915060-2-yanjun.zhu@linux.dev Signed-off-by: Zhu Yanjun Reviewed-by: Leon Romanovsky Signed-off-by: Jason Gunthorpe

RDMA/mad: Delete duplicated init_query_mad functions

Several drivers used same function to initialize query MAD, so move that function to global header file. Link: https://lore.kernel.org/r/af6f35c590ff5ef56d0137351b8b295af0f7c13c.1641369858.git.leonro@nvidia.com Signed-off-by: Leon Romanovsky Reviewed-by: Håkon Bugge Signed-off-by: Jason Gunthorpe

RDMA/netlink: Add __maybe_unused to static inline in C file

2021-11-16T17:13:08Z

Like other commits in the tree add __maybe_unused to a static inline in a C file because some clang compilers will complain about unused code: >> drivers/infiniband/core/nldev.c:2543:1: warning: unused function '__chk_RDMA_NL_NLDEV' MODULE_ALIAS_RDMA_NETLINK(RDMA_NL_NLDEV, 5); ^ Fixes: e3bf14bdc17a ("rdma: Autoload netlink client modules") Link: https://lore.kernel.org/r/4a8101919b765e01d7fde6f27fd572c958deeb4a.1636267207.git.leonro@nvidia.com Reported-by: kernel test robot Signed-off-by: Leon Romanovsky Signed-off-by: Jason Gunthorpe

RDMA/hns: Use the core code to manage the fixed mmap entries

Add a new implementation for mmap by using the new mmap entry API. This makes way for further use of the dynamic mmap allocator in this driver.

RDMA/umem: Allow pinned dmabuf umem usage

2021-10-28T11:58:26Z

Introduce ib_umem_dmabuf_get_pinned() which allows the driver to get a dmabuf umem which is pinned and does not require move_notify callback implementation. The returned umem is pinned and DMA mapped like standard cpu umems, and is released through ib_umem_release() (incl. unpinning and unmapping).

RDMA/core: Set sgtable nents when using ib_dma_virt_map_sg()

2021-10-13T18:26:41Z

ib_dma_map_sgtable_attrs() should be mapping the sgls and setting nents but the ib_uses_virt_dma() path falls back to ib_dma_virt_map_sg() which will not set the nents in the sgtable. Check the return value (per the map_sg calling convention) and set sgt->nents appropriately on success.

RDMA/mlx5: Add modify_op_stat() support

2021-10-12T15:48:06Z

Add support for ib callback modify_op_stat() to add or remove an optional counter. When adding, a steering flow table is created with a rule that catches and counts all the matching packets. When removing, the table and flow counter are destroyed.
