* batman-adv: Less function calls in batadv_is_ap_isolated() after error detectionMarkus Elfring2016-10-181-14/+11
| | | | | | | | | | | | | | The variables "tt_local_entry" and "tt_global_entry" were eventually checked again despite of a corresponding null pointer test before. * Avoid this double check by reordering a function call sequence and the better selection of jump targets. * Omit the initialisation for these variables at the beginning then.

| * net: phy: Trigger state machine on state change and not polling.Andrew Lunn2016-10-131-2/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The phy_start() is used to indicate the PHY is now ready to do its work. The state is changed, normally to PHY_UP which means that both the MAC and the PHY are ready. If the phy driver is using polling, when the next poll happens, the state machine notices the PHY is now in PHY_UP, and kicks off auto-negotiation, if needed. If however, the PHY is using interrupts, there is no polling. The phy is stuck in PHY_UP until the next interrupt comes along. And there is no reason for the PHY to interrupt. Have phy_start() schedule the state machine to run, which both speeds up the polling use case, and makes the interrupt use case actually work. This problems exists whenever there is a state change which will not cause an interrupt. Trigger the state machine in these cases, e.g. phy_error().

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Krister reported a kernel NULL pointer dereference after tcf_action_init_1() invokes a_o->init(), it is a race condition where one thread calling tcf_register_action() to initialize the netns data after putting act ops in the global list and the other thread searching the list and then calling a_o->init(net, ...). Fix this by moving the pernet ops registration before making the action ops visible. This is fine because: a) we don't rely on act_base in pernet ops->init(), b) in the worst case we have a fully initialized netns but ops is still not ready so new actions still can't be created.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If a VIF has been ready for rx_stall_timeout (60s by default) and an Rx ring is drained of all requests an Rx stall will be incorrectly detected. When this occurs and the guest Rx queue is empty, the Rx ring's event index will not be set and the frontend will not raise an event when new requests are placed on the ring, permanently stalling the VIF. This is a regression introduced by eb1723a29b9a7 (xen-netback: refactor guest rx). Fix this by reinstating the setting of queue->last_rx_time when placing a packet onto the guest Rx ring.

Our best guess is that the "set DTR" functionality depends on chipset and/or baseband firmware generation. But USB3 is still an optional feature. Since we cannot enable this unconditionally for all older devices, and there doesn't appear to be anything we can use in the USB descriptors to identify these chips, we are forced to use a device specific quirk flag.

| * tlan: avoid unused label with PCI=nArnd Bergmann2016-10-131-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | While build testing with randconfig on x86, I ran into this warning that appears to have been around forever drivers/net/ethernet/ti/tlan.c: In function ‘tlan_probe1’: drivers/net/ethernet/ti/tlan.c:614:1: error: label ‘err_out’ defined but not used [-Werror=unused-label] This can be trivially avoided by just moving the label into the existing #ifdef.

| * xen-netback: (re-)create a debugfs node for hash informationPaul Durrant2016-10-133-2/+107
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It is useful to be able to see the hash configuration when running tests. This patch adds a debugfs node for that purpose. The original version of this patch (commit c0c64c152389) was reverted due to build failures caused by a conflict with commit 0364a8824c02 ("xen-netback: switch to threaded irq for control ring"). This new version of the patch is nearly identical to the original, the only difference being that creation of the debugfs node is predicated on 'ctrl_irq' being non-zero rather then the now non-existent 'ctrl_task'.

| * net_sched: do not broadcast RTM_GETTFILTER resultEric Dumazet2016-10-131-7/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are two ways to get tc filters from kernel to user space. 1) Full dump (tc_dump_tfilter()) 2) RTM_GETTFILTER to get one precise filter, reducing overhead. The second operation is unfortunately broadcasting its result, polluting "tc monitor" users. This patch makes sure only the requester gets the result, using netlink_unicast() instead of rtnetlink_send() Jamal cooked an iproute2 patch to implement "tc filter get" operation, but other user space libraries already use RTM_GETTFILTER when a single filter is queried, instead of dumping all filters.

Overall, the plan is to use timespec64 and ktime_t for all internal kernel representation of timestamps. CURRENT_TIME will also be removed. boot_time is used to construct the nfs client boot verifier. Use ktime_t to represent boot_time and ktime_get_real() for the boot_time value. Following Trond's request https://lkml.org/lkml/2016/6/9/22 , use ktime_t instead of converting to struct timespec64. Use higher and lower 32 bit parts of ktime_t for the boot verifier. Use the lower 32 bit part of ktime_t for the authsys_parms stamp field.
