| e13619b6 | slavash | Dec. 5, 2018, 1:25 p.m. | ibcore: Fix clearing of bound device interface.
Binding to a loopback device is not allowed. Make sure the destination device address is global by clearing the bound device interface. Only do this conditionally, else link local addresses won't work. Submitted by: hselasky@ Approved by: hselasky (mentor) MFC after: 1 week Sponsored by: Mellanox Technologiescgit ViewVC |

| 5ace00df | slavash | Dec. 5, 2018, 1:24 p.m. | ibcore: Fix sleeping in atomic when RoCE is used
A couple of places in the CM do
spin_lock_irq(&cm_id_priv->lock);
...
if (cm_alloc_response_msg(work->port, work->mad_recv_wc, &msg))
However when the underlying transport is RoCE, this leads to a sleeping function
being called with the lock held - the callchain is
cm_alloc_response_msg() ->
ib_create_ah_from_wc() ->
ib_init_ah_from_wc() ->
rdma_addr_find_l2_eth_by_grh() ->
rdma_resolve_ip()
and rdma_resolve_ip() starts out by doing
req = kzalloc(sizeof *req, GFP_KERNEL);
not to mention rdma_addr_find_l2_eth_by_grh() doing
wait_for_completion(&ctx.comp);
to wait for the task that rdma_resolve_ip() queues up.
Fix this by moving the AH creation out of the lock.

| ae8534ca | slavash | Dec. 5, 2018, 1:23 p.m. | ibcore: Fix loopback with rdma-cm.
Trying to validate loopback fails because rtalloc1() resolves system local addresses to the loopback network interface, lo0. Fix this by explicitly checking for loopback during validation of the source and destination network address. If the source address belongs to a local network interface and is equal to the destination address, there is no need to run the destination address through rtalloc1().

The array ib_mad_mgmt_class_table.method_table has MAX_MGMT_CLASS (80) elements. Hence compare the array index with that value instead of with IB_MGMT_MAX_METHODS (128). This patch avoids that Coverity reports the following: Overrunning array class->method_table of 80 8-byte elements at element index 127 (byte offset 1016) using index convert_mgmt_class(mad_hdr->mgmt_class) (which evaluates to 127).
