The allocation for elem may fail (especially because we're using GFP_ATOMIC) so best to check for a null return. This fixes a potential null pointer dereference when assigning elem->pool.

On OPA devices opa_local_smp_check will receive 32Bit LIDs when the LID is Extended. In such cases, it is okay to lose the upper 16 bits of the LID as this information is obtained elsewhere. Do not issue a warning when calling ib_lid_cpu16() in this case by masking out the upper 16Bits.

When the link is disabled and re-enabled, the host version bit is not set again, so the firmware behaves as though it’s interacting with an old driver. This causes LNI to get out of sync. The host version bit needs to be set at load_8051_firmware() and _dc_start(). Currently, it's only set at load_8051_firmware(). Create a common function to set the bit with the intent to make the code more maintainable in the future, set the host version bit at _dc_start() and modify the 8051 command API to prevent a deadlock as _dc_start() is already holding the dc8051 lock.

For messages sent from the host to fw that solicit a reply from fw, the c4iw_wr_wait struct pointer is passed in the host->fw message, and included in the fw->host fw6_msg reply. This allows the sender to wait until the reply is received, and the code processing the ingress reply to wake up the sender. If c4iw_wait_for_reply() times out, however, we need to keep the c4iw_wr_wait object around in case the reply eventually does arrive. Otherwise we have touch-after-free bugs in the wake_up paths. This was hit due to a bad kernel driver that blocked ingress processing of cxgb4 for a long time, causing iw_cxgb4 timeouts, but eventually resuming ingress processing and thus hitting the touch-after-free bug. So I want to fix iw_cxgb4 such that we'll at least keep the wait object around until the reply comes. If it never comes we leak a small amount of memory, but if it does come late, we won't potentially crash the system. So add a kref struct in the c4iw_wr_wait struct, and take a reference before sending a message to FW that will generate a FW6 reply. And remove the reference (and potentially free the wait object) when the reply is processed. The ep code also uses the wr_wait for non FW6 CPL messages and doesn't embed the c4iw_wr_wait object in the message sent to firmware. So for those cases we add c4iw_wake_up_noref(). The mr/mw, cq, and qp object create/destroy paths do need this reference logic. For these paths, c4iw_ref_send_wait() is introduced to take the wr_wait reference, send the msg to fw, and then wait for the reply. So going forward, iw_cxgb4 either uses c4iw_ofld_send(), c4iw_wait_for_reply() and c4iw_wake_up_noref() like is done in the some of the endpoint logic, or c4iw_ref_send_wait() and c4iw_wake_up_deref() (formerly c4iw_wake_up()) when sending messages with the c4iw_wr_wait object pointer embedded in the message and resulting FW6 reply.

Use setup_timer and mod_timer API instead of structure assignments. This is done using Coccinelle and semantic patch used for this as follows: @@ expression x,y,z,a,b; @@ -init_timer (&x); +setup_timer (&x, y, z); +mod_timer (&a, b); -x.function = y; -x.data = z; -x.expires = b; -add_timer(&a); Signed-off-by:
