* RDMA/nes: Fix bugs in nes_reg_phys_mr()Don Wood2009-04-201-14/+13
| | | | | | | | | | | | | | The code incorrectly failed memory registration if the buffer was not page aligned. Also, the length field is mangled causing the hardware to think the registration is much larger than it really is. The fix is to remove the page alignment restriction as well the incorrect length adjustment. Also make sure that all buffers after the first start at a page boundary, and all buffers except the last end on a page boundary.

| * RDMA/nes: Fix nes_nic_cm_xmit() error handlingFaisal Latif2009-04-081-7/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We are getting crash or hung situation when we are running network cable pull tests during RDMA traffic. In schedule_nes_timer(), we return an error if nes_nic_cm_xmit() returns failure. This is changed to success as skb is being put on the timer routines to be processed later. In send_syn() case, we are indicating connect failure once from nes_connect() and the other when the rexmit retries expires. The other issue is skb->users which we are incrementing before calling nes_nic_cm_xmit() which calls dev_queue_xmit() but in case of failure we are decrementing the skb->users at the same time putting the skb on the rexmit path. Even if dev_queue_xmit() fails, the skb->users is decremented already. We are removing the decrement of skb->users in case of failure from both schedule_nes_timer() as well as from nes_cm_timer_tick(). There is also extra check in nes_cm_timer_tick() for rexmit failure which does a break from the loop is removed. This causes problem as the other nodes have their cm_node->ref_count incremented and are not processed.

To handle MPA Reject call, following changes are done: *Handle inbound/outbound MPA Reject response message. When nes_reject() is called for pending MPA request reply, send the MPA Reject message to its peer (active side)cm_node. The peer cm_node (active side) will indicate Reject message event for the pending Connect Request. *Handle MPA Reject response message for loopback connections and listener. When MPA Request is rejected, check if it is a loopback connection and if it is then it will send Reject message event to its peer loopback node. Also when destroying listener, check if the cm_nodes for that listener are loopback or not. *Add gracefull connection close with the MPA Reject response message. Send gracefull close (FIN, FIN ACK..) to terminate the cm_nodes. *Some code re-org while making the above changes. Removed recv_list and recv_list_lock from the cm_node structure as there can be only one receive close entry on the timer. Also implemented handle_recv_entry() as receive close entry is processed from both nes_rem_ref_cm_node() as well as nes_cm_timer_tick().

| * | RDMA/nes: Improve use of PBLsDon Wood2009-03-061-57/+134
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Two level 256 byte PBLs was not implemented so the driver could report out of memory when in fact there were PBLs still available. This solution prefers to use 4KB PBLs over two level 256B PBLs until the number of 4KB PBLs falls below a threshold. At this point the 4KB PBL structure is converted to use 256B PBLs which prevents the driver from running out of 4KB PBLs too quickly.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | NETIF_F_LLTX is deprecated. Remove private TX locking from the driver and remove the NETIF_F_LLTX feature flag. This also fixes a warning in some configs that comes from doing skb_linearize() call in the hard_start_xmit method with IRQs disabled (if HIGHMEM is enabled, skb_linearize() may end up enabling BHs, which is a no-no if hard IRQs are disabled in that context). By getting rid of LLTX, we do not disable IRQs when skb_linearize() is called. Remove the sq_lock as it is not needed for non-LLTX. Fix ethtool not to show the counter for sq_lock.

* | RDMA/nes: Don't allow userspace QPs to use STag zeroFaisal Latif2009-03-123-5/+37
|/ | | | | | | | | | | | | | | | | | | | | STag zero is a special STag that allows consumers to access any bus address without registering memory. The nes driver unfortunately allows STag zero to be used even with QPs created by unprivileged userspace consumers, which means that any process with direct verbs access to the nes device can read and write any memory accessible to the underlying PCI device (usually any memory in the system). Such access is usually given for cluster software such as MPI to use, so this is a local privilege escalation bug on most systems running this driver. The driver was using STag zero to receive the last streaming mode data; to allow STag zero to be disabled for unprivileged QPs, the driver now registers a special MR for this data.

There were a few things that had conflicts which I have just dropped for now, no harm done. I've built an allyesconfig with this and looked at the files that weren't built very carefully, but it's a huge patch. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: David S.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There is no lock protecting tx_free_list thus causing a system crash when skb_dequeue() is called and the list is empty. Since it did not give any performance boost under heavy load, remove it to simplify the code. Replace get_free_pkt() with dev_alloc_skb() to allocate MAX_CM_BUFFER skb for connection establishment/teardown as well as MPA request/response.

* | | RDMA/nes: Avoid race between MPA request and reset event to rdma_cmFaisal Latif2008-12-052-6/+49
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In passive open, after indicating MPA request to rdma_cm, an incoming RST would fire a reset event to rdma_cm causing it to crash, since the current state is not connected. The solution is to wait for nes_accept() or nes_reject() before firing the reset event. If nes_accept() or nes_reject() is already done, then the reset event will be fired when RST is processed.

Change some continue to break in nes_cm_timer_tick, because send_entry used to be a list processed in a loop (so continue went to the next item). Now it is a single item, so using break is correct.
