2020-05-06net: flow_offload: skip hw stats check for FLOW_ACTION_HW_STATS_DONT_CAREPablo Neira Ayuso1-1/+2
This patch adds FLOW_ACTION_HW_STATS_DONT_CARE which tells the driver that the frontend does not need counters, this hw stats type request never fails. The FLOW_ACTION_HW_STATS_DISABLED type explicitly requests the driver to disable the stats, however, if the driver cannot disable counters, it bails out. TCA_ACT_HW_STATS_* maintains the 1:1 mapping with FLOW_ACTION_HW_STATS_* except by disabled which is mapped to FLOW_ACTION_HW_STATS_DISABLED (this is 0 in tc). Add tc_act_hw_stats() to perform the mapping between TCA_ACT_HW_STATS_* and FLOW_ACTION_HW_STATS_*.

2020-05-06wireguard: send/receive: use explicit unlikely branch instead of implicit ↵Jason A. Donenfeld2-16/+12
coalescing It's very unlikely that send will become true. It's nearly always false between 0 and 120 seconds of a session, and in most cases becomes true only between 120 and 121 seconds before becoming false again. So, unlikely(send) is clearly the right option here. What happened before was that we had this complex boolean expression with multiple likely and unlikely clauses nested. Since this is evaluated left-to-right anyway, the whole thing got converted to unlikely. So, we can clean this up to better represent what's going on. The generated code is the same.

2020-05-06wireguard: send/receive: cond_resched() when processing worker ringbuffersJason A. Donenfeld2-0/+6
Users with pathological hardware reported CPU stalls on CONFIG_ PREEMPT_VOLUNTARY=y, because the ringbuffers would stay full, meaning these workers would never terminate. That turned out not to be okay on systems without forced preemption, which Sultan observed. This commit adds a cond_resched() to the bottom of each loop iteration, so that these workers don't hog the core. Note that we don't need this on the napi poll worker, since that terminates after its budget is expended.

2020-05-06wireguard: socket: remove errant restriction on looping to selfJason A. Donenfeld1-12/+0
It's already possible to create two different interfaces and loop packets between them. This has always been possible with tunnels in the kernel, and isn't specific to wireguard. Therefore, the networking stack already needs to deal with that. At the very least, the packet winds up exceeding the MTU and is discarded at that point. So, since this is already something that happens, there's no need to forbid the not very exceptional case of routing a packet back to the same interface; this loop is no different than others, and we shouldn't special case it, but rather rely on generic handling of loops in general. This also makes it easier to do interesting things with wireguard such as onion routing. At the same time, we add a selftest for this, ensuring that both onion routing works and infinite routing loops do not crash the kernel. We also add a test case for wireguard interfaces nesting packets and sending traffic between each other, as well as the loop in this case too. We make sure to send some throughput-heavy traffic for this use case, to stress out any possible recursion issues with the locks around workqueues.

The K3 INTA driver, which is source TX/RX IRQs for CPSW NUSS, defines IRQs triggering type as EDGE by default, but triggering type for CPSW NUSS TX/RX IRQs has to be LEVEL as the EDGE triggering type may cause unnecessary IRQs triggering and NAPI scheduling for empty queues. It was discovered with RT-kernel. Fix it by explicitly specifying CPSW NUSS TX/RX IRQ type as IRQF_TRIGGER_HIGH.

When running 'bridge fdb dump' on Felix, sometimes learnt and static MAC addresses would appear, sometimes they wouldn't. Turns out, the MAC table has 4096 entries on VSC7514 (Ocelot) and 8192 entries on VSC9959 (Felix), so the existing code from the Ocelot common library only dumped half of Felix's MAC table. They are both organized as a 4-way set-associative TCAM, so we just need a single variable indicating the correct number of rows.

2020-05-06net: dsa: sja1105: the PTP_CLK extts input reacts on both edgesVladimir Oltean1-8/+18
It looks like the sja1105 external timestamping input is not as generic as we thought. When fed a signal with 50% duty cycle, it will timestamp both the rising and the falling edge. When fed a short pulse signal, only the timestamp of the falling edge will be seen in the PTPSYNCTS register, because that of the rising edge had been overwritten. So the moral is: don't feed it short pulse inputs. Luckily this is not a complete deal breaker, as we can still work with 1 Hz square waves. But the problem is that the extts polling period was not dimensioned enough for this input signal. If we leave the period at half a second, we risk losing timestamps due to jitter in the measuring process. So we need to increase it to 4 times per second. Also, the very least we can do to inform the user is to deny any other flags combination than with PTP_RISING_EDGE and PTP_FALLING_EDGE both set.

asus-nb-wmi does not add any extra functionality on these Asus Transformer books. They have detachable keyboards, so the hotkeys are send through a HID device (and handled by the hid-asus driver) and also the rfkill functionality is not used on these devices. Besides not adding any extra functionality, initializing the WMI interface on these devices actually has a negative side-effect. For some reason the \_SB.ATKD.INIT() function which asus_wmi_platform_init() calls drives GPO2 (INT33FC:02) pin 8, which is connected to the front facing webcam LED, high and there is no (WMI or other) interface to drive this low again causing the LED to be permanently on, even during suspend.

Without this quirk the keyboard/touchpad combo works fine when connected at boot, but when hotplugged 9 out of 10 times it will not work properly. Adding the quirk fixes this.

2020-05-02vhost: vsock: kick send_pkt worker once device is startedJia He1-0/+5
Ning Bo reported an abnormal 2-second gap when booting Kata container [1]. The unconditional timeout was caused by VSOCK_DEFAULT_CONNECT_TIMEOUT of connecting from the client side. The vhost vsock client tries to connect an initializing virtio vsock server. The abnormal flow looks like: host-userspace vhost vsock guest vsock ============== =========== ============ connect() --------> vhost_transport_send_pkt_work() initializing | vq->private_data==NULL | will not be queued V schedule_timeout(2s) vhost_vsock_start() <--------- device ready set vq->private_data wait for 2s and failed connect() again vq->private_data!=NULL recv connecting pkt Details: 1. Host userspace sends a connect pkt, at that time, guest vsock is under initializing, hence the vhost_vsock_start has not been called. So vq->private_data==NULL, and the pkt is not been queued to send to guest 2. Then it sleeps for 2s 3. After guest vsock finishes initializing, vq->private_data is set 4. When host userspace wakes up after 2s, send connecting pkt again, everything is fine. As suggested by Stefano Garzarella, this fixes it by additional kicking the send_pkt worker in vhost_vsock_start once the virtio device is started. This makes the pending pkt sent again. After this patch, kata-runtime (with vsock enabled) boot time is reduced from 3s to 1s on a ThunderX2 arm64 server.

2020-05-01net: Make PTP-specific drivers depend on PTP_1588_CLOCKClay McClure5-5/+5
Commit d1cbfd771ce8 ("ptp_clock: Allow for it to be optional") changed all PTP-capable Ethernet drivers from `select PTP_1588_CLOCK` to `imply PTP_1588_CLOCK`, "in order to break the hard dependency between the PTP clock subsystem and ethernet drivers capable of being clock providers." As a result it is possible to build PTP-capable Ethernet drivers without the PTP subsystem by deselecting PTP_1588_CLOCK. Drivers are required to handle the missing dependency gracefully. Some PTP-capable Ethernet drivers (e.g., TI_CPSW) factor their PTP code out into separate drivers (e.g., TI_CPTS_MOD). The above commit also changed these PTP-specific drivers to `imply PTP_1588_CLOCK`, making it possible to build them without the PTP subsystem. But as Grygorii Strashko noted in [1]: On Wed, Apr 22, 2020 at 02:16:11PM +0300, Grygorii Strashko wrote: > Another question is that CPTS completely nonfunctional in this case and > it was never expected that somebody will even try to use/run such > configuration (except for random build purposes). In my view, enabling a PTP-specific driver without the PTP subsystem is a configuration error made possible by the above commit. Kconfig should not allow users to create a configuration with missing dependencies that results in "completely nonfunctional" drivers. I audited all network drivers that call ptp_clock_register() but merely `imply PTP_1588_CLOCK` and found five PTP-specific drivers that are likely nonfunctional without PTP_1588_CLOCK: NET_DSA_MV88E6XXX_PTP NET_DSA_SJA1105_PTP MACB_USE_HWSTAMP CAVIUM_PTP TI_CPTS_MOD Note how these symbols all reference PTP or timestamping in their name; this is a clue that they depend on PTP_1588_CLOCK. Change them from `imply PTP_1588_CLOCK` [2] to `depends on PTP_1588_CLOCK`. I'm not using `select PTP_1588_CLOCK` here because PTP_1588_CLOCK has its own dependencies, which `select` would not transitively apply. Additionally, remove the `select NET_PTP_CLASSIFY` from CPTS_TI_MOD; PTP_1588_CLOCK already selects that. [1]: https://lore.kernel.org/lkml/c04458ed-29ee-1797-3a11-7f3f560553e6@ti.com/ [2]: NET_DSA_SJA1105_PTP had never declared any type of dependency on PTP_1588_CLOCK (`imply` or otherwise); adding a `depends on PTP_1588_CLOCK` here seems appropriate.

2020-05-01hv_netvsc: Fix netvsc_start_xmit's return typeNathan Chancellor1-1/+2
netvsc_start_xmit is used as a callback function for the ndo_start_xmit function pointer. ndo_start_xmit's return type is netdev_tx_t but netvsc_start_xmit's return type is int. This causes a failure with Control Flow Integrity (CFI), which requires function pointer prototypes and callback function definitions to match exactly. When CFI is in enforcing, the kernel panics. When booting a CFI kernel with WSL 2, the VM is immediately terminated because of this. The splat when CONFIG_CFI_PERMISSIVE is used: [ 5.916765] CFI failure (target: netvsc_start_xmit+0x0/0x10): [ 5.916771] WARNING: CPU: 8 PID: 0 at kernel/cfi.c:29 __cfi_check_fail+0x2e/0x40 [ 5.916772] Modules linked in: [ 5.916774] CPU: 8 PID: 0 Comm: swapper/8 Not tainted 5.7.0-rc3-next-20200424-microsoft-cbl-00001-ged4eb37d2c69-dirty #1 [ 5.916776] RIP: 0010:__cfi_check_fail+0x2e/0x40 [ 5.916777] Code: 48 c7 c7 70 98 63 a9 48 c7 c6 11 db 47 a9 e8 69 55 59 00 85 c0 75 02 5b c3 48 c7 c7 73 c6 43 a9 48 89 de 31 c0 e8 12 2d f0 ff <0f> 0b 5b c3 00 00 cc cc 00 00 cc cc 00 00 cc cc 00 00 85 f6 74 25 [ 5.916778] RSP: 0018:ffffa803c0260b78 EFLAGS: 00010246 [ 5.916779] RAX: 712a1af25779e900 RBX: ffffffffa8cf7950 RCX: ffffffffa962cf08 [ 5.916779] RDX: ffffffffa9c36b60 RSI: 0000000000000082 RDI: ffffffffa9c36b5c [ 5.916780] RBP: ffff8ffc4779c2c0 R08: 0000000000000001 R09: ffffffffa9c3c300 [ 5.916781] R10: 0000000000000151 R11: ffffffffa9c36b60 R12: ffff8ffe39084000 [ 5.916782] R13: ffffffffa8cf7950 R14: ffffffffa8d12cb0 R15: ffff8ffe39320140 [ 5.916784] FS: 0000000000000000(0000) GS:ffff8ffe3bc00000(0000) knlGS:0000000000000000 [ 5.916785] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 [ 5.916786] CR2: 00007ffef5749408 CR3: 00000002f4f5e000 CR4: 0000000000340ea0 [ 5.916787] Call Trace: [ 5.916788] <IRQ> [ 5.916790] __cfi_check+0x3ab58/0x450e0 [ 5.916793] ? dev_hard_start_xmit+0x11f/0x160 [ 5.916795] ? sch_direct_xmit+0xf2/0x230 [ 5.916796] ? __dev_queue_xmit.llvm.11471227737707190958+0x69d/0x8e0 [ 5.916797] ? neigh_resolve_output+0xdf/0x220 [ 5.916799] ? neigh_connected_output.cfi_jt+0x8/0x8 [ 5.916801] ? ip6_finish_output2+0x398/0x4c0 [ 5.916803] ? nf_nat_ipv6_out+0x10/0xa0 [ 5.916804] ? nf_hook_slow+0x84/0x100 [ 5.916807] ? ip6_input_finish+0x8/0x8 [ 5.916807] ? ip6_output+0x6f/0x110 [ 5.916808] ? __ip6_local_out.cfi_jt+0x8/0x8 [ 5.916810] ? mld_sendpack+0x28e/0x330 [ 5.916811] ? ip_rt_bug+0x8/0x8 [ 5.916813] ? mld_ifc_timer_expire+0x2db/0x400 [ 5.916814] ? neigh_proxy_process+0x8/0x8 [ 5.916816] ? call_timer_fn+0x3d/0xd0 [ 5.916817] ? __run_timers+0x2a9/0x300 [ 5.916819] ? rcu_core_si+0x8/0x8 [ 5.916820] ? run_timer_softirq+0x14/0x30 [ 5.916821] ? __do_softirq+0x154/0x262 [ 5.916822] ? native_x2apic_icr_write+0x8/0x8 [ 5.916824] ? irq_exit+0xba/0xc0 [ 5.916825] ? hv_stimer0_vector_handler+0x99/0xe0 [ 5.916826] ? hv_stimer0_callback_vector+0xf/0x20 [ 5.916826] </IRQ> [ 5.916828] ? hv_stimer_global_cleanup.cfi_jt+0x8/0x8 [ 5.916829] ? raw_setsockopt+0x8/0x8 [ 5.916830] ? default_idle+0xe/0x10 [ 5.916832] ? do_idle.llvm.10446269078108580492+0xb7/0x130 [ 5.916833] ? raw_setsockopt+0x8/0x8 [ 5.916833] ? cpu_startup_entry+0x15/0x20 [ 5.916835] ? cpu_hotplug_enable.cfi_jt+0x8/0x8 [ 5.916836] ? start_secondary+0x188/0x190 [ 5.916837] ? secondary_startup_64+0xa5/0xb0 [ 5.916838] ---[ end trace f2683fa869597ba5 ]--- Avoid this by using the right return type for netvsc_start_xmit.
