Pull networking fixes from David Miller: 1) L2TP doesn't get autoloaded when you try to open an L2TP socket due to a missing module alias, fix from Benjamin LaHaise. 2) Netlabel and RDS should propagate gfp flags given to them by callers, fixes from Dan Carpeneter. 3) Recursive locking fix in usbnet wasn't bulletproof and can result in objects going away mid-flight due to races, fix from Ming Lei. 4) Fix up some confusion about a bool module parameter in netfilter's iptable_filter and ip6table_filter, from Rusty Russell. 5) If SKB recycling is used via napi_reuse_skb() we end up with different amounts of headroom reserved than we had at the original SKB allocation. Fix from Eric Dumazet. 6) Fix races in TG3 driver ring refilling, from Michael Chan. 7) We have callbacks for IPSEC replay notifiers, but some call sites were not using the ops method and instead were calling one of the implementations directly. Oops. Fix from Steffen Klassert. 8) Fix IP address validation properly in the bonding driver, the previous fix only works with netlink where the subnet mask and IP address are changed in one atomic operation. When 'ifconfig' ioctls are used the IP address and the subnet mask are changed in two distinct operations. Fix from Andy Gospodarek. 9) Provide a sky2 module operation to work around power management issues with some BIOSes.

The recently added parity error handling used an error code that was already defined for a different error. This could lead to bnx2x firmware assert. We need to fix this with new error codes that are defined for parity error only.

2011-12-14[SCSI] bnx2i: Fixed kernel panic caused by unprotected task->sc->request derefEddie Wai
During session recovery, the conn_stop call will trigger a flush to all outstanding SCSI cmds in the xmit queue. This will set all outstanding task->sc to NULL prior to the session_teardown call which frees the task memory. In the bnx2i SCSI response processing path, only the task was being checked for NULL under the session lock before the task->sc->request dereferencing. If there are outstanding SCSI cmd responses pending for process, the following kernel panic can be exposed where task->sc was found to be NULL.

2011-07-21[SCSI] bnx2i: Fixed kernel panic due to illegal usage of sc->request->cpuEddie Wai
A kernel panic was observed when passing the sc->request->cpu = -1 to retrieve the per_cpu variable pointer: #0 [ffff880011203960] machine_kexec at ffffffff81022bc3 #1 [ffff8800112039b0] crash_kexec at ffffffff81088630 #2 [ffff880011203a80] __die at ffffffff8139ea20 #3 [ffff880011203aa0] no_context at ffffffff8102f3a7 #4 [ffff880011203ae0] __bad_area_nosemaphore at ffffffff8102f665 #5 [ffff880011203ba0] retint_signal at ffffffff8139dd1f #6 [ffff880011203cc8] bnx2i_indicate_kcqe at ffffffffa03dc4f2 #7 [ffff880011203da8] service_kcqes at ffffffffa03cb04f #8 [ffff880011203e68] cnic_service_bnx2x_kcq at ffffffffa03cb14a #9 [ffff880011203e88] cnic_service_bnx2x_bh at ffffffffa03cb1b3 The problem lies in the slow path sg_io (and perhaps sg_scsi_ioctl) call to blk_get_request->get_request/wait->blk_alloc_request->blk_rq_init which re-initializes the request->cpu to -1. There is no assignment for cpu from that to the request_fn call to low level drivers. When this happens, the sc->request->cpu will be using the init value of -1. This will create a kernel panic when it hits bnx2i because the code refers it to get the per_cpu variables ptr. This change is to put in a guard against that and also for cases when bio affinity/queue completion to the same cpu is not enabled. In those cases, the request->cpu will remain a -1 also. This bug was created from commit: b5cf6b63f73abdc051035f0050b367beeb2ef94c For the case when the blk layer did not setup the request->cpu, bnx2i will complete the sc with the current CPU of the thread.

2011-06-29[SCSI] bnx2i: Added the use of kthreads to handle SCSI cmd completionEddie Wai
This patch breaks the SCSI cmd completion into two parts: 1. The bh will allocate and queued work to the cmd specific CPU IO completion kthread. The CPU for the cmd is from the sc->request->cpu. 2. The CPU specific IO completion kthread will call the scsi_cmd_resp routine to do the actual cmd completion. In the normal case, these IO completion kthreads should complete before the blk IO times out at 60s. However, in the case when these kthreads are blocked for whatever reason and exceeded the timeout, the call to conn_destroy will have to iterate and exhaust all related work in the percpu work list for all online CPUs. This will guarantee the protection of the work->session and conn pointers before they get freed. Also modified the event coalescing formula to have at least the event_coal_min outstanding cmds in the pipeline so the SCSI producer would not get underrun. Also changed the following SCSI parameters: - can_queue from 1024 to 2048 - cmds_per_lun from 24 to 128 Signed-off-by: Eddie Wai <eddie.wai@broadcom.com> Acked-by: Benjamin Li <benli@broadcom.com> Acked-by: Michael Chan <mchan@broadcom.com> Signed-off-by: James Bottomley <JBottomley@Parallels.com>

New implementation of the HSI handling layer in the bnx2x (bnx2x_sp.c): - Introduced chip dependent objects that have chip independent interfaces for configuration of MACs, multicast addresses, Rx mode, indirection table, fast path queues and function initialization/cleanup. - Objects functionality is based on the private function pointers, which allows not only a per-chip but also PF/VF differentiation while still preserving the same interface towards the driver. - Objects interface is not influenced by the HSI changes which do not require providing new parameters keeping the code outside the bnx2x_sp.c invariant with regard to such HSI chnages.

2011-05-24[SCSI] bnx2i: Optimized the iSCSI offload performanceEddie Wai
Modified the event coalescing code for iSCSI offload to combat both corner cases and optimize performance as follows: 1. Added mechanism to loop back a second time to process any leftover CQEs that was generated by the hardware during the time the driver is busy processing previous CQEs in the bh. This not only helps the performance but also fixes the corner case when no more CQEs are being generated in the pipeline; so those leftover CQEs will get a a chance to be processed. 2. Added ARM_CQE_FP to distinguish between fast path arming versus slow path arming. This change will guarantee that the CQEs will always get a chance to be re-armed during fast path completions. 3. Removed the inline event coalescing division for perf optimization. Also fixed a division-by-zero error when the event_coal_div module param was set to 0. 4. Changed the default SQ WQEs size from 256 to 128 to match chip default. 5. Changed the cmd_per_lun from 32 to 24.

The number of chip's internal command cell, which is use to generate SCSI cmd packets to the target, was not initialized correctly by the driver when the sq_size is changed from the default 128. This, in turn, will create a problem where the chip's transmit pipe will erroneously reuse an old command cell that is no longer valid.

2010-12-23cnic: Improve ->iscsi_nl_msg_send()Michael Chan
1. Change first parameter from cnic_dev to ulp_handle which is the hba pointer. All other similar upcalls are using hba pointer. The callee can then directly reference the hba without conversion. 2. Change return value from void to int so that an error code can be passed back. This allows the operation to be retried. Signed-off-by: Michael Chan <mchan@broadcom.com> Signed-off-by: David S.

2010-12-21[SCSI] bnx2i: Cleaned up various error conditions in ep_connect/disconnectEddie Wai
Various error conditions inside ep_connect and ep_disconnect were either not being handled or not being handled correctly. This patch fixes all those issues.

2010-12-21[SCSI] bnx2i: Added return code check for chip kwqe submission requestEddie Wai
Added the handling for cases when a chip request is made to the CNIC module but the hardware is not ready to accept. This would lead to many unnecessary wait timeouts. This code adds check in the connect establishment and destruction path.

2010-12-21[SCSI] bnx2i: Modified the bnx2i stop path to compensate for in progress opsEddie Wai
The stop path has been augmented to wait a max of 10s for all in progress offload and destroy activities to complete before proceeding to terminate all active connections (via iscsid or forcefully). Note that any new offload and destroy requests are now blocked and return to the caller immediately.

2010-12-21[SCSI] bnx2i: Allow to abort the connection if connect request times outEddie Wai
In the situation where the connect completion response arrives after the connect request has already timed out, the connection was not being aborted but only the resource was being freed. This creates a problem for 5771X (10g) as the chip flags this with an assertion. This change will properly aborts the connection before freeing the resource.
