When ipoib_ib_dev_flush() is called because of a port event, the driver needs to rejoin all multicast groups, since the flush will call ipoib_mcast_dev_flush() (via ipoib_ib_dev_down()). Otherwise no (non-broadcast) multicast groups will be rejoined until the networking core calls ->set_multicast_list again, and so multicast reception will be broken for potentially a long time.

Split up ipoib_ib_handle_wc() into ipoib_ib_handle_rx_wc() and ipoib_ib_handle_tx_wc() to make the code easier to read. This will also help implement NAPI in the future. Signed-off-by: NRoland Dreier <rolandd@cisco.com>

The comparisons of priv->tx_tail to ah->last_send in ipoib_free_ah() and ipoib_post_receive() are slightly unsafe, because priv->tx_lock is not held and hence a stale value of ah->last_send might be used, which would lead to freeing an AH before the driver was really done with it. The simple way to fix this is to the optimization of early free from ipoib_free_ah() and unconditionally queue AHs for reaping, and then take priv->tx_lock in __ipoib_reap_ah().

When ipoib_stop() is called it first calls netif_stop_queue() to stop the kernel from passing more packets to the network driver. However, the completion handler may call netif_wake_queue() re-enabling packet transfer. This might result in leaks (we see AH leaks which we think can be attributed to this bug) as new packets get posted while the interface is going down.

Make IPoIB's send and receive queue sizes tunable via module parameters ("send_queue_size" and "recv_queue_size"). This allows the queue sizes to be enlarged to fix disastrously bad performance on some platforms and workloads, without bloating memory usage when large queues aren't needed.

This patch causes the network interface to respond to P_Key change events correctly. As a result, you'll see a child interface in the "RUNNING" state (netif_carrier_on()) only when the corresponding P_Key is configured by the SM. When SM removes a P_Key, the "RUNNING" state will be disabled for the corresponding network interface. To implement this, I added IB_EVENT_PKEY_CHANGE event handling. To prevent flushing the device before the device is open by the "delay open" mechanism, I added an additional device flag called IPOIB_FLAG_INITIALIZED. This also prevents the child network interface from trying to join to multicast groups until the PKEY is configured. We used to get error messages like: ib0.f2f2: couldn't attach QP to multicast group ff12:401b:f2f2:0:0:0:ffff:ffff in this case. To fix this, I just check IPOIB_FLAG_OPER_UP flag in ipoib_set_mcast_list(). Signed-off-by: NLeonid Arsh <leonida@voltaire.com> Signed-off-by: NRoland Dreier <rolandd@cisco.com>

Move ipoib_ib_dev_flush() to ipoib's workqueue. This keeps it ordered with respect to other work scheduled by the ipoib driver. This fixes problems with races, for example: - ipoib_ib_dev_flush() has started running because of an IB event - user does ifconfig ib0 down - ipoib_mcast_stop_thread() gets called twice and waits for the same completion twice Signed-off-by: NJack Morgenstein <jackm@mellanox.co.il> Signed-off-by: NMichael S.

The current handling of multicast groups in IPoIB ends up never freeing send-only multicast groups. It turns out the logic was much more complicated than it needed to be; we can fix this bug and completely kill ipoib_mcast_dev_down() at the same time.

Change the way IPoIB handles RX packets when it can't allocate a new receive skbuff. If the allocation of a new receive skb fails, we now drop the packet we just received and repost the original receive skb. This means that the receive ring always stays full and we don't have to monkey around with trying to schedule a refill task for later. Signed-off-by: NRoland Dreier <rolandd@cisco.com>

ipoib_create_qp() no longer creates IPoIB's QP, so it shouldn't destroy the QP on failure -- that unwinding happens elsewhere, so the current code can cause a double free. While we're at it, the function's name should match what it actually does, so rename it to ipoib_init_qp(). Signed-off-by: NRoland Dreier <rolandd@cisco.com>

ipoib_mcast_restart_task() is always called from within the single-threaded IPoIB workqueue, so flushing the workqueue from within the function can lead to a recursion overflow. But since we're running in a single-threaded workqueue, we're already synchronized against other items in the workqueue, so just get rid of the flush in ipoib_mcast_restart_task().

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!
