| * iscsi-target: Convert gfp_t parameter to task state bitmaskNicholas Bellinger2014-01-251-7/+7
| | | | | | | | | | | | | | | | | | | | | | | | This patch propigates the use of task state bitmask now used by percpu_ida_alloc() up the iscsi-target callchain, replacing the use of GFP_ATOMIC for TASK_RUNNING, and GFP_KERNEL for TASK_INTERRUPTIBLE. Also, drop the unnecessary gfp_t parameter to isert_allocate_cmd(), and just pass TASK_INTERRUPTIBLE into iscsit_allocate_cmd(). Signed-off-by: Nicholas Bellinger <nab@linux-iscsi.org>

Changes to inet4 and inet6 addresses for the host are monitored and if the address is associated with an ocrdma device then a gid is added or deleted from the device's gid table. The gid format will be a IPv4 to IPv6 mapped or the IPv6 address.

Change this scheme such that gids encode interface IP addresses (both IP4 and IPv6). This requires learning the IP addresses which are of use by a netdevice associated with the HCA port, formatting them to gids and adding them to the port gid table. Furthermore, events of add and delete address are caught to maintain the gid table accordingly. Associated IP addresses may belong to a master of an Ethernet netdevice on top of that port so this should be considered when building and maintaining the gid table.

Change GIDs to be treated as they encode interface IP address. Since Ethernet layer 2 address parameters are not longer encoded within gids, we have to extend the Infiniband address structures (e.g. ib_ah_attr) with layer 2 address parameters, namely mac and vlan.

| * | | IB/core: Ethernet L2 attributes in verbs/cm structuresMatan Barak2014-01-1412-21/+277

When dealing with L2 Ethernet, we should use smac, dmac, vlan ID and priority in a similar manner that the IB L2 (and the L4 PKEY) attributes are used. Thus, those attributes were added to the following structures: * ib_ah_attr - added dmac * ib_qp_attr - added smac and vlan_id, (sl remains vlan priority) * ib_wc - added smac, vlan_id * ib_sa_path_rec - added smac, dmac, vlan_id * cm_av - added smac and vlan_id For the path record structure, extra care was taken to avoid the new fields when packing it into wire format, so we don't break the IB CM and SA wire protocol. On the active side, the CM fills. its internal structures from the path provided by the ULP. We add there taking the ETH L2 attributes and placing them into the CM Address Handle (struct cm_av). On the passive side, the CM fills its internal structures from the WC associated with the REQ message. We add there taking the ETH L2 attributes from the WC. When the HW driver provides the required ETH L2 attributes in the WC, they set the IB_WC_WITH_SMAC and IB_WC_WITH_VLAN flags. The IB core code checks for the presence of these flags, and in their absence does address resolution from the ib_init_ah_from_wc() helper function. ib_modify_qp_is_ok is also updated to consider the link layer. Some parameters are mandatory for Ethernet link layer, while they are irrelevant for IB. Vendor drivers are modified to support the new function signature.

In some of these instances, the call is made while holding a spinlock. Change all WARN_ON(spin_is_locked...) calls in usNIC to lockdep_assert_held to make it fool-proof bc the latter can be called while holding a spinlock and unlike spin_is_locked, lockdep_assert_held also works correctly on UP.
