2018-02-28timers: Forward timer base before migrating timersLingutla Chandrasekhar1-0/+6
On CPU hotunplug the enqueued timers of the unplugged CPU are migrated to a live CPU. This happens from the control thread which initiated the unplug. If the CPU on which the control thread runs came out from a longer idle period then the base clock of that CPU might be stale because the control thread runs prior to any event which forwards the clock. In such a case the timers from the unplugged CPU are queued on the live CPU based on the stale clock which can cause large delays due to increased granularity of the outer timer wheels which are far away from base:;clock. But there is a worse problem than that. The following sequence of events illustrates it: - CPU0 timer1 is queued expires = 59969 and base->clk = 59131. The timer is queued at wheel level 2, with resulting expiry time = 60032 (due to level granularity). - CPU1 enters idle @60007, with next timer expiry @60020. - CPU0 is hotplugged at @60009 - CPU1 exits idle and runs the control thread which migrates the timers from CPU0 timer1 is now queued in level 0 for immediate handling in the next softirq because the requested expiry time 59969 is before CPU1 base->clk 60007 - CPU1 runs code which forwards the base clock which succeeds because the next expiring timer. which was collected at idle entry time is still set to 60020. So it forwards beyond 60007 and therefore misses to expire the migrated timer1. That timer gets expired when the wheel wraps around again, which takes between 63 and 630ms depending on the HZ setting. Address both problems by invoking forward_timer_base() for the control CPUs timer base. All other places, which might run into a similar problem (mod_timer()/add_timer_on()) already invoke forward_timer_base() to avoid that.

In that case, the checks for xenbus_read_driver_state would return XenbusStateUnknown, and xennet_remove would hang indefinitely.

Current cleanup in the error path of xen_bind_pirq_msi_to_irq is wrong. First of all there's an off-by-one in the cleanup loop, which can lead to unbinding wrong IRQs.

IB spec says that a lid should be ignored when link layer is Ethernet, for example when building or parsing a CM request message (CA17-34). However, since ib_lid_be16() and ib_lid_cpu16() validates the slid, not only when link layer is IB, we set the slid to zero to prevent false warnings in the kernel log.

All other mlx5_events report the port number as 1 based, which is how FW reports it in the port event EQE. Reporting 0 for this event causes mlx5_ib to not raise a fatal event notification to registered clients due to a seemingly invalid port. All switch cases in mlx5_ib_event that go through the port check are supposed to set the port now, so just do it once at variable declaration.

During QP creation, the mlx5 driver translates the QP type to an internal value which is passed on to FW. There was no check to make sure that the translated value is valid, and -EINVAL was coerced into the mailbox command.

2018-02-28ipvs: remove IPS_NAT_MASK check to fix passive FTPJulian Anastasov1-1/+1
The IPS_NAT_MASK check in 4.12 replaced previous check for nfct_nat() which was needed to fix a crash in 2.6.36-rc, see commit 7bcbf81a2296 ("ipvs: avoid oops for passive FTP"). But as IPVS does not set the IPS_SRC_NAT and IPS_DST_NAT bits, checking for IPS_NAT_MASK prevents PASV response to be properly mangled and blocks the transfer. Remove the check as it is not needed after 3.12 commit 41d73ec053d2 ("netfilter: nf_conntrack: make sequence number adjustments usuable without NAT") which changes nfct_nat() with nfct_seqadj() and especially after 3.13 commit b25adce16064 ("ipvs: correct usage/allocation of seqadj ext in ipvs").

2018-02-28ARC: mcip: halt GFRC counter when ARC cores haltEugeniy Paltsev2-0/+40
In SMP systems, GFRC is used for clocksource. However by default the counter keeps running even when core is halted (say when debugging via a JTAG debugger). This confuses Linux timekeeping and triggers flase RCU stall splat such as below: | [ARCLinux]# while true; do ./shm_open_23-1.run-test ; done | Running with 1000 processes for 1000 objects | hrtimer: interrupt took 485060 ns | | create_cnt: 1000 | Running with 1000 processes for 1000 objects | [ARCLinux]# INFO: rcu_preempt self-detected stall on CPU | 2-...: (1 GPs behind) idle=a01/1/0 softirq=135770/135773 fqs=0 | INFO: rcu_preempt detected stalls on CPUs/tasks: | 0-...: (1 GPs behind) idle=71e/0/0 softirq=135264/135264 fqs=0 | 2-...: (1 GPs behind) idle=a01/1/0 softirq=135770/135773 fqs=0 | 3-...: (1 GPs behind) idle=4e0/0/0 softirq=134304/134304 fqs=0 | (detected by 1, t=13648 jiffies, g=31493, c=31492, q=1) Starting from ARC HS v3.0 it's possible to tie GFRC to state of up-to 4 ARC cores with help of GFRC's CORE register where we set a mask for cores which state we need to rely on. We update cpu mask every time new cpu came online instead of using hardcoded one or using mask generated from "possible_cpus" as we want it set correctly even if we run kernel on HW which has fewer cores than expected (or we launch kernel via debugger and kick fever cores than HW has) Note that GFRC halts when all cores have halted and thus relies on programming of Inter-Core-dEbug register to halt all cores when one halts.

2018-02-28spectrum: Reference count VLAN entriesIdo Schimmel2-1/+8
One of the basic construct in the device is a port-VLAN pair, which can be bound to a FID or a RIF in order to direct packets to the bridge or the router, respectively. Since not all the netdevs are configured with a VLAN (e.g., sw1p1 vs. sw1p1.10), VID 1 is used to represent these and thus this VID can be used by both upper devices of mlxsw ports and by the driver itself. However, this VID is not reference counted and therefore might be freed prematurely, which can result in various WARNINGs. For example: $ ip link add name br0 type bridge vlan_filtering 1 $ teamd -t team0 -d -c '{"runner": {"name": "lacp"}}' $ ip link set dev team0 master br0 $ ip link set dev enp1s0np1 master team0 $ ip address add 192.0.2.1/24 dev enp1s0np1 The enslavement to team0 will fail because team0 already has an upper and thus vlan_vids_del_by_dev() will be executed as part of team's error path which will delete VID 1 from enp1s0np1 (added by br0 as PVID). The WARNING will be generated when the driver will realize it can't find VID 1 on the port and bind it to a RIF. Fix this by adding a reference count to the VLAN entries on the port, in a similar fashion to the reference counting used by the corresponding 'vlan_vid_info' structure in the 8021q driver.

2018-02-28mlxsw: spectrum: Treat IPv6 unregistered multicast as broadcastIdo Schimmel1-1/+1
When multicast snooping is enabled, the Linux bridge resorts to flooding unregistered multicast packets to all ports only in case it did not detect a querier in the network. The above condition is not reflected to underlying drivers, which is especially problematic in IPv6 environments, as multicast snooping is enabled by default and since neighbour solicitation packets might be treated as unregistered multicast packets in case there is no corresponding MDB entry. Until the Linux bridge reflects its querier state to underlying drivers, simply treat unregistered multicast packets as broadcast and allow them to reach their destination.
