Raw Normal View History

Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

[PATCH] IB: Add copyright notices Make some lawyers happy and add copyright notices for people who forgot to include them when they actually touched the code. Signed-off-by: Roland Dreier <rolandd@cisco.com>

[PATCH] IB: move include files to include/rdma Move the InfiniBand headers from drivers/infiniband/include to include/rdma. This allows InfiniBand-using code to live elsewhere, and lets us remove the ugly EXTRA_CFLAGS include path from the InfiniBand Makefiles. Signed-off-by: Roland Dreier <rolandd@cisco.com>

IB/core: Provide rdma_ versions of the gid cache API These versions are functionally similar but all return gid_attrs and related information via reference instead of via copy. The old API is preserved, implemented as wrappers around the new, until all callers can be converted.

RDMA: Introduce and use GID attr helper to read RoCE L2 fields Instead of RoCE drivers figuring out vlan, smac fields while working on QP/AH, provide a helper routine to read the L2 fields such as vlan_id and source mac address. This moves logic from mlx5 driver to core for wider usage for RoCE ports. This is a preparation patch to allow detaching netdev in subsequent patch.

RDMA/cma: Use rdma_read_gid_attr_ndev_rcu to access netdev To access the netdevice of the GID attribute, use an existing API rdma_read_gid_attr_ndev_rcu(). This further reduces dependency on open access to netdevice of GID attribute.

IB/core: Add ib_find_exact_cached_pkey() When P_Key tables potentially contain both full and partial membership copies for the same P_Key, we need a function to find the index for an exact (16-bit) P_Key. This is necessary when the master forwards QP1 MADs sent by guests. If the guest has sent the MAD with a limited membership P_Key, we need to to forward the MAD using the same limited membership P_Key. Since the master may have both the limited and the full member P_Keys in its table, we must make sure to retrieve the limited membership P_Key in this case.

IB/core: Introduce GID attribute get, put and hold APIs This patch introduces three APIs, rdma_get_gid_attr(), rdma_put_gid_attr(), and rdma_hold_gid_attr() which expose the reference counting for GID table entries to the entire stack. The kref counting is based on the struct ib_gid_attr pointer Later patches will convert more cache query function to return struct ib_gid_attrs.

IB/cache: Restore compatibility for ib_query_gid Code changes in smc have become so complicated this cycle that the RDMA patches to remove ib_query_gid in smc create too complex merge conflicts. Allow those conflicts to be resolved by using the net/smc hunks by providing a compatibility wrapper. During the second phase of the merge window this wrapper will be deleted and smc updated to use the new API.
