cxgbi_inet6addr_handler() can be called in interrupt context, so use rcu protected list while finding netdev. This is observed as a scheduling in atomic oops when running over ipv6.

Pull networking fixes from David Miller: 1) If the user gives us a msg_namelen of 0, don't try to interpret anything pointed to by msg_name. From Ani Sinha. 2) Fix some bnx2i/bnx2fc randconfig compilation errors. The gist of the issue is that we firstly have drivers that span both SCSI and networking. And at the top of that chain of dependencies we have things like SCSI_FC_ATTRS and SCSI_NETLINK which are selected. But since select is a sledgehammer and ignores dependencies, everything to select's SCSI_FC_ATTRS and/or SCSI_NETLINK has to also explicitly select their dependencies and so on and so forth. Generally speaking 'select' is supposed to only be used for child nodes, those which have no dependencies of their own. And this whole chain of dependencies in the scsi layer violates that rather strongly. So just make SCSI_NETLINK depend upon it's dependencies, and so on and so forth for the things selecting it (either directly or indirectly). From Anish Bhatt and Randy Dunlap. 3) Fix generation of blackhole routes in IPSEC, from Steffen Klassert. 4) Actually notice netdev feature changes in rtl_open() code, from Hayes Wang. 5) Fix divide by zero in bond enslaving, from Nikolay Aleksandrov. 6) Missing memory barrier in sunvnet driver, from David Stevens. 7) Don't leave anycast addresses around when ipv6 interface is destroyed, from Sabrina Dubroca. 8) Don't call efx_{arch}_filter_sync_rx_mode before addr_list_lock is initialized in SFC driver, from Edward Cree. 9) Fix missing DMA error checking in 3c59x, from Neal Horman. 10) Openvswitch doesn't emit OVS_FLOW_CMD_NEW notifications accidently, fix from Samuel Gauthier. 11) pch_gbe needs to select NET_PTP_CLASSIFY otherwise we can get a build error. 12) Fix macvlan regression wherein we stopped emitting broadcast/multicast frames over software devices. From Nicolas Dichtel. 13) Fix infiniband bug due to unintended overflow of skb->cb[], from Eric Dumazet. And add an assertion so this doesn't happen again. 14) dm9000_parse_dt() should return error pointers, not NULL. From Tobias Klauser. 15) IP tunneling code uses this_cpu_ptr() in preemptible contexts, fix from Eric Dumazet. * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net: (87 commits) net: bcmgenet: call bcmgenet_dma_teardown in bcmgenet_fini_dma net: bcmgenet: fix TX reclaim accounting for fragments ipv4: do not use this_cpu_ptr() in preemptible context dm9000: Return an ERR_PTR() in all error conditions of dm9000_parse_dt() r8169: fix an if condition r8152: disable ALDPS ipoib: validate struct ipoib_cb size net: sched: shrink struct qdisc_skb_cb to 28 bytes tg3: Work around HW/FW limitations with vlan encapsulated frames macvlan: allow to enqueue broadcast pkt on virtual device pch_gbe: 'select' NET_PTP_CLASSIFY. scsi: Use 'depends' with LIBFC instead of 'select'. openvswitch: restore OVS_FLOW_CMD_NEW notifications genetlink: add function genl_has_listeners() lib: rhashtable: remove second linux/log2.h inclusion net: allow macvlans to move to net namespace 3c59x: Fix bad offset spec in skb_frag_dma_map 3c59x: Add dma error checking and recovery sparc: bpf_jit: fix support for ldx/stx mem and SKF_AD_VLAN_TAG can: at91_can: add missing prepare and unprepare of the clock ...
2014-09-22scsi: Use 'depends' with LIBFC instead of 'select'.David S. Miller
LIBFC depends upon SCSI_FC_ATTRS and select's CRC32C. The only alternative would be to 'select' CRC32C and all of SCSI_FC_ATTRS direct and indirect dependencies in the Kconfig section for every LIBFCOE user which makes little sense. Subsequently, use 'depends' instead of 'select' for LIBFCOE too. Signed-off-by: David S. Miller <davem@davemloft.net>
2014-09-19[SCSI] fix for bidi use after freeDaniel Gryniewicz
When ending a bi-directionional SCSI request, blk_finish_request() cleans up and frees the request, but scsi_release_bidi_buffers() tries to indirect through the request to find it's data buffers. This causes a panic due to a null pointer dereference. Move the call to scsi_release_bidi_buffers() before the call to blk_finish_request().

2014-09-16scsi: use 'depends' instead of 'select' for SCSI_FC_ATTRSRandy Dunlap
There are other kconfig symbols which use SCSI_FC_ATTRS. In order to maintain sanity and prevent kconfig warnings, change all of these from using 'select' to using 'depends on' so that proper symbol dependencies will be honored and circular depends problems will be avoided.

These need to be handled separately as they select CNIC, which can override tristate for CNIC from 'm' to 'y', which can cause build failures when ipv6 is compiled as a module even if CNIC's Kconfig will only 'm' or 'n' when ipv6 is compiled as a module.

2014-08-15[SCSI] save command pool address of Scsi_HostJuergen Gross
If a scsi host driver specifies .cmd_len in it's scsi_host_template, a driver's private command pool is needed. scsi_find_host_cmd_pool() will locate it, but scsi_alloc_host_cmd_pool() isn't saving the pool address in the host template. This will result in an access error when the host is removed. Avoid the problem by saving the address of a new allocated command pool where it is expected.

git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace Pull tracing updates from Steven Rostedt: "This pull request has a lot of work done. The main thing is the changes to the ftrace function callback infrastructure. It's introducing a way to allow different functions to call directly different trampolines instead of all calling the same "mcount" one. The only user of this for now is the function graph tracer, which always had a different trampoline, but the function tracer trampoline was called and did basically nothing, and then the function graph tracer trampoline was called. The difference now, is that the function graph tracer trampoline can be called directly if a function is only being traced by the function graph trampoline. If function tracing is also happening on the same function, the old way is still done. The accounting for this takes up more memory when function graph tracing is activated, as it needs to keep track of which functions it uses. I have a new way that wont take as much memory, but it's not ready yet for this merge window, and will have to wait for the next one. Another big change was the removal of the ftrace_start/stop() calls that were used by the suspend/resume code that stopped function tracing when entering into suspend and resume paths. The stop of ftrace was done because there was some function that would crash the system if one called smp_processor_id()! The stop/start was a big hammer to solve the issue at the time, which was when ftrace was first introduced into Linux. Now ftrace has better infrastructure to debug such issues, and I found the problem function and labeled it with "notrace" and function tracing can now safely be activated all the way down into the guts of suspend and resume Other changes include clean ups of uprobe code, clean up of the trace_seq() code, and other various small fixes and clean ups to ftrace and tracing" * tag 'trace-3.17' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace: (57 commits) ftrace: Add warning if tramp hash does not match nr_trampolines ftrace: Fix trampoline hash update check on rec->flags ring-buffer: Use rb_page_size() instead of open coded head_page size ftrace: Rename ftrace_ops field from trampolines to nr_trampolines tracing: Convert local function_graph functions to static ftrace: Do not copy old hash when resetting tracing: let user specify tracing_thresh after selecting function_graph ring-buffer: Always run per-cpu ring buffer resize with schedule_work_on() tracing: Remove function_trace_stop and HAVE_FUNCTION_TRACE_MCOUNT_TEST s390/ftrace: remove check of obsolete variable function_trace_stop arm64, ftrace: Remove check of obsolete variable function_trace_stop Blackfin: ftrace: Remove check of obsolete variable function_trace_stop metag: ftrace: Remove check of obsolete variable function_trace_stop microblaze: ftrace: Remove check of obsolete variable function_trace_stop MIPS: ftrace: Remove check of obsolete variable function_trace_stop parisc: ftrace: Remove check of obsolete variable function_trace_stop sh: ftrace: Remove check of obsolete variable function_trace_stop sparc64,ftrace: Remove check of obsolete variable function_trace_stop tile: ftrace: Remove check of obsolete variable function_trace_stop ftrace: x86: Remove check of obsolete variable function_trace_stop ...

2014-08-01scsi_transport_srp: Fix fast_io_fail_tmo=dev_loss_tmo=off behaviorBart Van Assche
If scsi_remove_host() is called while an rport is in the blocked state then scsi_remove_host() will only finish if the rport is unblocked from inside a timer function. Make sure that an rport only enters the blocked state if a timer will be started that will unblock it. This avoids that unloading the ib_srp kernel module after having disconnected the initiator from the target system results in a deadlock if both the fast_io_fail_tmo and dev_loss_tmo parameters have been set to "off".
