Hi,
New series from Parav and Jason:
------------------
Now that we have stable pointers to the gid_attrs in the GID table, we can
replace lookups in the cache with pointer de-references throughout the
stack from the core to the drivers.
HW objects that touch gid entires will hold a reference to the gid_attrs
for their lifetime. In RoCE mode this prevents reuse of the GID index
while there is an active user, which prevents a security/functional issue
around re-assigned GID table entries.
After this series there is only one driver call remaining to the GID cache
(in RXE receive) and driver use of the grh.sgid_index has been substantially
reduced.
Thanks
Jason Gunthorpe (3):
IB/core: Add a sgid_attr pointer to struct rdma_ah_attr
IB{cm, core}: Introduce and use ah_attr copy, move, replace APIs
RDMA: Hold the sgid_attr inside the struct ib_ah/qp
Parav Pandit (5):
IB: Ensure that all rdma_ah_attr's are zero initialized
IB/core: Tidy ib_resolve_eth_dmac
RDMA: Convert drivers to use sgid_attr instead of sgid_index
IB/mlx4: Use GID attribute from ah attribute
RDMA: Convert drivers to use the AH's sgid_attr in post_wr paths
