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

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | If the max receive frame size is changed during link down, the driver uses the same value after linkup unless it is reset to default. Signed-off-by: Bhanu Prakash Gollapudi <bprakash@broadcom.com> Signed-off-by: James Bottomley <JBottomley@Parallels.com>

| | | | | | | | | | | | | | | | | | This patch adds a validation step before allowing creation of a new NPIV port. It checks whether the WWPN passed for the new NPIV port to be created is unique for the given physical port.

| | | | | | | | | | | | | | | | As an initiator, driver need not handle incoming ABTS. It initiates an ABTS if any IO requests time out. Signed-off-by: Bhanu Prakash Gollapudi <bprakash@broadcom.com> Signed-off-by: James Bottomley <JBottomley@Parallels.com>

| | | | | | | | | | | | | | | | | | | | | | - Free session resources before rport logoff - Do not free session resources in bnx2fc_alloc_session_resc() as it is handled in caller's error handling path. - Do not call bnx2fc_free_session_resc() if bnx2fc_init_tgt() fails as cq_lock is not yet initialized.

| * [SCSI] bnx2fc: Fix NULL pointer deref during arm_cq.Bhanu Prakash Gollapudi2011-08-272-11/+18
| | | | | | | | | | | | | | | | | | | | | | | | There exists a race condition between CQ doorbell unmap and IO completion path that arms the CQ which causes a NULL dereference. Protect the ctx_base with cq_lock to avoid this. Also, wait for the CQ doorbell to be successfully mapped before arming the CQ. Also, do not count uncolicited CQ completions for free_sqes.

| | | | | | | | | | | | | | | | | | | | During the unsolicited LOGO processing, the session is uploaded and offloaded after the relogin is complete. In between any new IOs are errored back as the upload completion flag is set. Upon exhausting the retry count, the application fails the IOs. Return target busy for all the cases when session is not ready. Signed-off-by: Bhanu Prakash Gollapudi <bprakash@broadcom.com> Signed-off-by: James Bottomley <JBottomley@Parallels.com>

| | | | | | | | | | | | | | | | Since this flag was never cleared, the driver does not wait for firmware destroy completions, causing missed KCQEs. Signed-off-by: Bhanu Prakash Gollapudi <bprakash@broadcom.com> Signed-off-by: James Bottomley <JBottomley@Parallels.com>

| | | | | | | | | | | | | | | | | | Since the driver holds the reference for vlan netdev, the reference has to be released by the driver when the vlan device is removed. Driver handles this in NETDEV_UNREGISTER event. Signed-off-by: Bhanu Prakash Gollapudi <bprakash@broadcom.com> Signed-off-by: James Bottomley <JBottomley@Parallels.com>

| | | | | | | | | | | | | | | | | | | | Move interface specific cleanup functionality to from bnx2fc_if_destroy to bnx2fc_interface_cleanup. Do not access interface/hba in bnx2fc_if_destroy as by the time this function is called interface may already be destroyed. This patch is in preparation to handle NETDEV_UNREGISTER on a vlan device.

| * [SCSI] bnx2fc: Do not attempt destroying NPIV port twiceBhanu Prakash Gollapudi2011-08-271-0/+12
| | | | | | | | | | | | | | | | | | | | When NPIV ports are created/deleted rapidly there is a race condition between bnx2fc_vport_destroy() from sysfs and bnx2fc_flogi_resp(), which could try to delete the NPIV port from the list twice. Fix is to loop through the list of NPIV ports to find a match, and only when it exists remove it.
