2009-04-08RDMA/nes: Fix SFP+ PHY initializationChien Tung
SFP+ PHY initialization has very long delays, incorrect settings for direct attach copper cables, and inconsistent link detection. Adjust delays to the minimum required by the PHY. Worst case is now less than 4 seconds. Add new register settings for direct attach cables. Change link detection logic to use two new registers for more consistent link state detection. Reorganize code to shorten line length. Signed-off-by: Chien Tung <chien.tin.tung@intel.com> Signed-off-by: Roland Dreier <rolandd@cisco.com>
2009-04-08RDMA/nes: Fix nes_nic_cm_xmit() error handlingFaisal Latif
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.

2009-04-08RDMA/nes: Fix error handling issuesFaisal Latif
Fix issues found by static code analysis: (1) Check if cm_node was successfully created for loopback connection. (2) schedule_nes_timer() does not free up allocated memory after encountering an error. There is a WARN_ON() for this condition. (3) there is a cm_node->freed flag which is set but not used.

2009-04-08RDMA/nes: Fix incorrect casts on 32-bit architecturesDon Wood
The were some incorrect casts to unsigned long that caused 64-bit values to be truncated on 32-bit architectures and made the driver pass invalid adresses and lengths to the hardware.

2009-03-30RDMA/cxgb3: Release dependent resources only when endpoint memory is freed.Steve Wise
The cxgb3 l2t entry, hwtid, and dst entry were being released before all the iwch_ep references were released. This can cause a crash in t3_l2t_send_slow() and other places where the l2t entry is used. The fix is to defer releasing these resources until all endpoint references are gone. Details: - move flags field to the iwch_ep_common struct. - add a flag indicating resources are to be released. - release resources at endpoint free time instead of close/abort time.

2009-03-24RDMA/cxgb3: Enforce required firmwareSteve Wise
The cxgb3 NIC driver can handle more firmware versions than iw_cxgb3, and since commit 8207befa ("cxgb3: untie strict FW matching") cxgb3 will load with firmware versions that iw_cxgb3 can't handle. The FW major number indicates a specific interface between the FW and iw_cxgb3. Thus if the major number of the running firmware does not match the required version compiled into iw_cxgb3, then iw_cxgb3 must not register that device.

2009-03-12RDMA/nes: Don't allow userspace QPs to use STag zeroFaisal Latif
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.

2009-03-06RDMA/nes: Handle MPA Reject message properlyFaisal Latif
While doing testing, there are failures as MPA Reject call is not handled. 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().

2009-03-06RDMA/nes: Improve use of PBLsDon Wood
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.

2009-03-06RDMA/nes: Remove LLTXFaisal Latif
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.

2009-02-18timers: add mod_timer_pending()Ingo Molnar
Impact: new timer API Based on an idea from Martin Josefsson with the help of Patrick McHardy and Stephen Hemminger: introduce the mod_timer_pending() API which is a mod_timer() offspring that is an invariant on already removed timers. (regular mod_timer() re-activates non-pending timers.) This is useful for the networking code in that it can allow unserialized mod_timer_pending() timer-forwarding calls, but a single del_timer*() will stop the timer from being reactivated again. Also while at it: - optimize the regular mod_timer() path some more, the timer-stat and a debug check was needlessly duplicated in __mod_timer(). - make the exports come straight after the function, as most other exports in timer.c already did. - eliminate __mod_timer() as an external API, change the users to mod_timer(). The regular mod_timer() code path is not impacted significantly, due to inlining optimizations and due to the simplifications.

2009-01-28IB/mthca: Fix dispatch of IB_EVENT_LID_CHANGE eventMoni Shoua
When snooping a PortInfo MAD, its client_reregister bit is checked. If the bit is ON then a CLIENT_REREGISTER event is dispatched, otherwise a LID_CHANGE event is dispatched. This way of decision ignores the cases where the MAD changes the LID along with an instruction to reregister (so a necessary LID_CHANGE event won't be dispatched) or the MAD is neither of these (and an unnecessary LID_CHANGE event will be dispatched). This causes problems at least with IPoIB, which will do a "light" flush on reregister, rather than the "heavy" flush required due to a LID change. Fix this by dispatching a CLIENT_REREGISTER event if the client_reregister bit is set, but also compare the LID in the MAD to the current LID.
