Merge tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/rdma/rdma
Pull rdma fixes from Jason Gunthorpe:
"Several significant bug fixes of pre-existing issues:
- Missing validation on ucap fd types passed from userspace
- Missing validation of HW DMA space vs userpace expected sizes in
EFA queue setup
- DMA corruption when using DMA block sizes >= 4G when setting up MRs
in all drivers
- Missing validation of CPU IDs when setting up dma handles
- Missing validation of IB_MR_REREG_ACCESS when changing writability
of a MR
- Missing validation of received message/packet size in ISER and SRP"
* tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/rdma/rdma:
RDMA/srp: bound SRP_RSP sense copy by the received length
IB/isert: Reject login PDUs shorter than ISER_HEADERS_LEN
RDMA: During rereg_mr ensure that REREG_ACCESS is compatible
RDMA/core: Validate cpu_id against nr_cpu_ids in DMAH alloc
RDMA/umem: Fix truncation for block sizes >= 4G
RDMA/efa: Validate SQ ring size against max LLQ size
RDMA/core: Validate the passed in fops for ib_get_ucaps()
