As of kernel 4.10, ALSA dice driver is expected to be used in default speed. In most cases, it's S400. While, IEEE 1394 specification describes the other speed such as S800. According to 'TCD30XX User Guide', its link layer controller supports several transmission speed up to S800[0]. In Dice software interface, transmission speed in output direction can be configured by asynchronous transaction to 'TX_SPEED' offset in its address space. S800 may be available. This commit improves configuration of transmission unit before starting packet streaming for this purpose. The value of 'max_speed' in 'fw_device' data structure has available maximum speed decided in bus arbitration, thus it's within capacity of the unit.

As of kernel 4.10, ALSA OXFW driver has no entry for Onyx 1640i produced by Mackie (Loud Technologies). This commit supplement it. I note that there're two models produced by Mackie (Loud Technologies), which have the same name 'Onyx 1640i'. The former model based on OXFW970, the latter model based on Dice. This is probably due to low quality of communication of OXFW series. Additionally, the tester reports his or her experiences to get unexpected result at higher sampling transmission frequency as 88.2/96.0 kHz.

Pull networking fixes from David Miller: 1) Various ipvlan fixes from Eric Dumazet and Mahesh Bandewar. The most important is to not assume the packet is RX just because the destination address matches that of the device. Such an assumption causes problems when an interface is put into loopback mode. 2) If we retry when creating a new tc entry (because we dropped the RTNL mutex in order to load a module, for example) we end up with -EAGAIN and then loop trying to replay the request. But we didn't reset some state when looping back to the top like this, and if another thread meanwhile inserted the same tc entry we were trying to, we re-link it creating an enless loop in the tc chain. Fix from Daniel Borkmann. 3) There are two different WRITE bits in the MDIO address register for the stmmac chip, depending upon the chip variant. Due to a bug we could set them both, fix from Hock Leong Kweh. 4) Fix mlx4 bug in XDP_TX handling, from Tariq Toukan. * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net: net: stmmac: fix incorrect bit set in gmac4 mdio addr register r8169: add support for RTL8168 series add-on card. net: xdp: remove unused bfp_warn_invalid_xdp_buffer() openvswitch: upcall: Fix vlan handling. ipv4: Namespaceify tcp_tw_reuse knob net: korina: Fix NAPI versus resources freeing net, sched: fix soft lockup in tc_classify net/mlx4_en: Fix user prio field in XDP forward tipc: don't send FIN message from connectionless socket ipvlan: fix multicast processing ipvlan: fix various issues in ipvlan_process_multicast()

Networking stack accelerate vlan tag handling by keeping topmost vlan header in skb. This works as long as packet remains in OVS datapath. But during OVS upcall vlan header is pushed on to the packet. When such packet is sent back to OVS datapath, core networking stack might not handle it correctly. Following patch avoids this issue by accelerating the vlan tag during flow key extract. This simplifies datapath by bringing uniform packet processing for packets from all code paths.

Shahar reported a soft lockup in tc_classify(), where we run into an endless loop when walking the classifier chain due to tp->next == tp which is a state we should never run into. The issue only seems to trigger under load in the tc control path. What happens is that in tc_ctl_tfilter(), thread A allocates a new tp, initializes it, sets tp_created to 1, and calls into tp->ops->change() with it. In that classifier callback we had to unlock/lock the rtnl mutex and returned with -EAGAIN. One reason why we need to drop there is, for example, that we need to request an action module to be loaded. This happens via tcf_exts_validate() -> tcf_action_init/_1() meaning after we loaded and found the requested action, we need to redo the whole request so we don't race against others. While we had to unlock rtnl in that time, thread B's request was processed next on that CPU. Thread B added a new tp instance successfully to the classifier chain. When thread A returned grabbing the rtnl mutex again, propagating -EAGAIN and destroying its tp instance which never got linked, we goto replay and redo A's request. This time when walking the classifier chain in tc_ctl_tfilter() for checking for existing tp instances we had a priority match and found the tp instance that was created and linked by thread B. Now calling again into tp->ops->change() with that tp was successful and returned without error. tp_created was never cleared in the second round, thus kernel thinks that we need to link it into the classifier chain (once again). tp and *back point to the same object due to the match we had earlier on. Thus for thread B's already public tp, we reset tp->next to tp itself and link it into the chain, which eventually causes the mentioned endless loop in tc_classify() once a packet hits the data path. Fix is to clear tp_created at the beginning of each request, also when we replay it. On the paths that can cause -EAGAIN we already destroy the original tp instance we had and on replay we really need to start from scratch. It seems that this issue was first introduced in commit 12186be7 ("net_cls: fix unconfigured struct tcf_proto keeps chaining and avoid kernel panic when we use cls_cgroup").

I am getting the following warning when I build kernel 4.9-git on my PowerBook G4 with a 32-bit PPC processor: AS arch/powerpc/kernel/misc_32.o arch/powerpc/kernel/misc_32.S:299:7: warning: "CONFIG_FSL_BOOKE" is not defined [-Wundef] This problem is evident after commit 989cea5c ("kbuild: prevent lib-ksyms.o rebuilds"); however, this change in kbuild only exposes an error that has been in the code since 2005 when this source file was created.

The timer type simplifications caused a new gcc warning: drivers/base/power/domain.c: In function ‘genpd_runtime_suspend’: drivers/base/power/domain.c:562:14: warning: ‘time_start’ may be used uninitialized in this function [-Wmaybe-uninitialized] elapsed_ns = ktime_to_ns(ktime_sub(ktime_get(), time_start)); despite the actual use of "time_start" not having changed in any way. It appears that simply changing the type of ktime_t from a union to a plain scalar type made gcc check the use. The variable wasn't actually used uninitialized, but gcc apparently failed to notice that the conditional around the use was exactly the same as the conditional around the initialization of that variable. Add an unnecessary initialization just to shut up the compiler. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

Add a new page flag, PageWaiters, to indicate the page waitqueue has tasks waiting. This can be tested rather than testing waitqueue_active which requires another cacheline load. This bit is always set when the page has tasks on page_waitqueue(page), and is set and cleared under the waitqueue lock. It may be set when there are no tasks on the waitqueue, which will cause a harmless extra wakeup check that will clears the bit. The generic bit-waitqueue infrastructure is no longer used for pages. Instead, waitqueues are used directly with a custom key type. The generic code was not flexible enough to have PageWaiters manipulation under the waitqueue lock (which simplifies concurrency). This improves the performance of page lock intensive microbenchmarks by 2-3%. Putting two bits in the same word opens the opportunity to remove the memory barrier between clearing the lock bit and testing the waiters bit, after some work on the arch primitives (e.g., ensuring memory operand widths match and cover both bits).

hotcpu_notifier(), cpu_notifier(), __hotcpu_notifier(), __cpu_notifier(), register_hotcpu_notifier(), register_cpu_notifier(), __register_hotcpu_notifier(), __register_cpu_notifier(), unregister_hotcpu_notifier(), unregister_cpu_notifier(), __unregister_hotcpu_notifier(), __unregister_cpu_notifier() are unused now. Remove them and all related code. Remove also the now pointless cpu notifier error injection mechanism. The states can be executed step by step and error rollback is the same as cpu down, so any state transition can be tested w/o requiring the notifier error injection. Some CPU hotplug states are kept as they are (ab)used for hotplug state tracking.

Install the callbacks via the state machine. No functional change. This is the minimal fixup so we can remove the hotplug notifier mess completely. The real rework of this driver to use work queues is still stuck in review/testing on the SCSI mailing list. Signed-off-by: Sebastian Andrzej Siewior <bigeasy@linutronix.de> Cc: "James E.J.
