Delete successive tests to the same location. The code tested the result of a previous allocation, that itself was already tested. It is changed to test the result of the most recent allocation.

2013-01-29[SCSI] bnx2fc: Map the doorbell register between offload and enable requestsBhanu Prakash Gollapudi
We used to map doorbell register after FW enable request is complete. This causes a race condition when unsolicited event is received, and FW sends a CQE for it. Since the doorbell is not mapped, driver does not arm CQ, which means FW will not notify the driver for further CQ completions. To resolve this, map the doorbell between offload and enable, so that driver is ready to receive the unsolicited packets and arm the CQ as soon as FW enable is performed.

This change removes the use of __devinit, __devexit_p, __devinitdata, __devinitconst, and __devexit from these drivers.

2012-12-14bnx2fc: Use the fcoe_sysfs control interfaceRobert Love
This patch adds support for the new fcoe_sysfs control interface to bnx2fc.ko. It keeps the deprecated interface in tact and therefore either the legacy or the new control interfaces can be used. A mixed mode is not supported. A user must either use the new interfaces or the old ones, but not both. The fcoe_ctlr's link state is now driven by both the netdev link state as well as the fcoe_ctlr_device's enabled attribute. The link must be up and the fcoe_ctlr_device must be enabled before the FCoE Controller starts discovery or login.

2012-12-14libfcoe, fcoe, bnx2fc: Add new fcoe control interfaceRobert Love
This patch does a few things. 1) Makes /sys/bus/fcoe/ctlr_{create,destroy} interfaces. These interfaces take an <ifname> and will either create an FCoE Controller or destroy an FCoE Controller depending on which file is written to. The new FCoE Controller will start in a DISABLED state and will not do discovery or login until it is ENABLED. This pause will allow us to configure the FCoE Controller before enabling it. 2) Makes the 'mode' attribute of a fcoe_ctlr_device writale. This allows the user to configure the mode in which the FCoE Controller will start in when it is ENABLED. Possible modes are 'Fabric', or 'VN2VN'. The default mode for a fcoe_ctlr{,_device} is 'Fabric'. Drivers must implement the set_fcoe_ctlr_mode routine to support this feature. libfcoe offers an exported routine to set a FCoE Controller's mode. The mode can only be changed when the FCoE Controller is DISABLED. This patch also removes the get_fcoe_ctlr_mode pointer in the fcoe_sysfs function template, the code in fcoe_ctlr.c to get the mode and the assignment of the fcoe_sysfs function pointer to the fcoe_ctlr.c implementation (in fcoe and bnx2fc). fcoe_sysfs can return that value for the mode without consulting the LLD. 3) Make a 'enabled' attribute of a fcoe_ctlr_device. On a read, fcoe_sysfs will return the attribute's value. On a write, fcoe_sysfs will call the LLD (if there is a callback) to notifiy that the enalbed state has changed. This patch maintains the old FCoE control interfaces as module parameters, but it adds comments pointing out that the old interfaces are deprecated.

2012-07-20[SCSI] bnx2fc: Improve error recovery by handling parity errorsBhanu Prakash Gollapudi
During parity errors, the ramrods are not issued to FW. bnx2fc waits for the timeout value, and proceeds with cleaning up the IOs. Since we are already out-of-sync with FW, cleanup commands timeout too, and do not get the completion. This operation takes 36 secs for each session to upload causing huge delays. To fix this, bnx2fc now gets a PARITY_ERROR from cnic driver, and upon failure, the driver does not issue any commands to the FW and finishes the upload process sooner.

This patch has the SW FCoE driver and the bnx2fc driver make use of the new fcoe_sysfs API added earlier in this patch series. After this patch a fcoe_ctlr_device is allocated with private data in this order. +------------------+ +------------------+ | fcoe_ctlr_device | | fcoe_ctlr_device | +------------------+ +------------------+ | fcoe_ctlr | | fcoe_ctlr | +------------------+ +------------------+ | fcoe_interface | | bnx2fc_interface | +------------------+ +------------------+ libfcoe also takes part in this new model since it discovers and manages fcoe_fcf instances. The memory allocation is different for FCFs. I didn't want to impact libfcoe's fcoe_fcf processing, so this patch creates fcoe_fcf_device instances for each discovered fcoe_fcf. The two are paired using a (void * priv) member of the fcoe_ctlr_device. This allows libfcoe to continue maintaining its list of fcoe_fcf instances and simply attaches and detaches them from existing or new fcoe_fcf_device instances.

2012-05-23[SCSI] bnx2fc: Allocate fcoe_ctlr with bnx2fc_interface, not as a memberRobert Love
Currently the fcoe_ctlr associated with an interface is allocated as a member of struct bnx2fc_interface. This causes problems when when later patches attempt to use the new fcoe_sysfs APIs which allow us to allocate the bnx2fc_interface as private data to a fcoe_ctlr_device instance. The problem is that libfcoe wants to be able use pointer math to find a fcoe_ctlr's fcoe_ctlr_device as well as finding a fcoe_ctlr_device's assocated fcoe_ctlr. To do this we need to allocate the fcoe_ctlr_device, with private data for the LLD. The private data will contain the fcoe_ctlr and its private data will be the bnx2fc_interface. +-------------------+ | fcoe_ctlr_device | +-------------------+ | fcoe_ctlr | +-------------------+ | bnx2fc_interface | +-------------------+ This prep work will allow us to go from a fcoe_ctlr_device instance to its fcoe_ctlr as well as from a fcoe_ctlr to its fcoe_ctlr_device once the fcoe_sysfs API is in use (later patches in this series).

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. From Stephen Hemminger. * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net: usbnet: consider device busy at each recieved packet bonding: remove entries for master_ip and vlan_ip and query devices instead netfilter: remove forward module param confusion. usbnet: don't clear urb->dev in tx_complete usbnet: increase URB reference count before usb_unlink_urb xfrm: Access the replay notify functions via the registered callbacks xfrm: Remove unused xfrm_state from xfrm_state_check_space RDS: use gfp flags from caller in conn_alloc() netlabel: use GFP flags from caller instead of GFP_ATOMIC l2tp: enable automatic module loading for l2tp_ppp cnic: Fix parity error code conflict tg3: Fix RSS ring refill race condition sky2: override for PCI legacy power management net: fix napi_reuse_skb() skb reserve

2012-03-22cnic: Fix parity error code conflictMichael Chan
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.

When there are 255 NPIV ports, and the interface is brought down & up, both physical and NPIV ports are logged off and never logged back in. Since discovery happens on single CPU, XID resources on that CPU will be limited, which when exhausted the discovery fails. Increase the XID resource range to ensure that the discovery completes successfully. Also ensure that fc_exch_mgr_alloc() doesn't fail on the system that has lower number of CPUs.
