So when geneve link down, we will not able to show remote address and checksum info after commit 11387fe4a98 ("geneve: fix fill_info when using collect_metadata").

2017-11-15usbnet: ipheth: prevent TX queue timeouts when device not readyAlexander Kappner1-9/+21
iOS devices require the host to be "trusted" before servicing network packets. Establishing trust requires the user to confirm a dialog on the iOS device.Until trust is established, the iOS device will silently discard network packets from the host. Currently, the ipheth driver does not detect whether an iOS device has established trust with the host, and immediately sets up the transmit queues. This causes the following problems: - Kernel taint due to WARN() in netdev watchdog. - Dmesg spam ("TX timeout"). - Disruption of user space networking activity (dhcpd, etc...) when new interface comes up but cannot be used. - Unnecessary host and device wakeups and USB traffic Example dmesg output: [ 1101.319778] NETDEV WATCHDOG: eth1 (ipheth): transmit queue 0 timed out [ 1101.319817] ------------[ cut here ]------------ [ 1101.319828] WARNING: CPU: 0 PID: 0 at net/sched/sch_generic.c:316 dev_watchdog+0x20f/0x220 [ 1101.319831] Modules linked in: ipheth usbmon nvidia_drm(PO) nvidia_modeset(PO) nvidia(PO) iwlmvm mac80211 iwlwifi btusb btrtl btbcm btintel qmi_wwan bluetooth cfg80211 ecdh_generic thinkpad_acpi rfkill [last unloaded: ipheth] [ 1101.319861] CPU: 0 PID: 0 Comm: swapper/0 Tainted: P O 4.13.12.1 #1 [ 1101.319864] Hardware name: LENOVO 20ENCTO1WW/20ENCTO1WW, BIOS N1EET62W (1.35 ) 11/10/2016 [ 1101.319867] task: ffffffff81e11500 task.stack: ffffffff81e00000 [ 1101.319873] RIP: 0010:dev_watchdog+0x20f/0x220 [ 1101.319876] RSP: 0018:ffff8810a3c03e98 EFLAGS: 00010292 [ 1101.319880] RAX: 000000000000003a RBX: 0000000000000000 RCX: 0000000000000000 [ 1101.319883] RDX: ffff8810a3c15c48 RSI: ffffffff81ccbfc2 RDI: 00000000ffffffff [ 1101.319886] RBP: ffff880c04ebc41c R08: 0000000000000000 R09: 0000000000000379 [ 1101.319889] R10: 00000100696589d0 R11: 0000000000000378 R12: ffff880c04ebc000 [ 1101.319892] R13: 0000000000000000 R14: 0000000000000001 R15: ffff880c2865fc80 [ 1101.319896] FS: 0000000000000000(0000) GS:ffff8810a3c00000(0000) knlGS:0000000000000000 [ 1101.319899] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 [ 1101.319902] CR2: 00007f3ff24ac000 CR3: 0000000001e0a000 CR4: 00000000003406f0 [ 1101.319905] DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000 [ 1101.319908] DR3: 0000000000000000 DR6: 00000000fffe0ff0 DR7: 0000000000000400 [ 1101.319910] Call Trace: [ 1101.319914] <IRQ> [ 1101.319921] ? dev_graft_qdisc+0x70/0x70 [ 1101.319928] ? dev_graft_qdisc+0x70/0x70 [ 1101.319934] ? call_timer_fn+0x2e/0x170 [ 1101.319939] ? dev_graft_qdisc+0x70/0x70 [ 1101.319944] ? run_timer_softirq+0x1ea/0x440 [ 1101.319951] ? timerqueue_add+0x54/0x80 [ 1101.319956] ? enqueue_hrtimer+0x38/0xa0 [ 1101.319963] ? __do_softirq+0xed/0x2e7 [ 1101.319970] ? irq_exit+0xb4/0xc0 [ 1101.319976] ? smp_apic_timer_interrupt+0x39/0x50 [ 1101.319981] ? apic_timer_interrupt+0x8c/0xa0 [ 1101.319983] </IRQ> [ 1101.319992] ? cpuidle_enter_state+0xfa/0x2a0 [ 1101.319999] ? do_idle+0x1a3/0x1f0 [ 1101.320004] ? cpu_startup_entry+0x5f/0x70 [ 1101.320011] ? start_kernel+0x444/0x44c [ 1101.320017] ? early_idt_handler_array+0x120/0x120 [ 1101.320023] ? x86_64_start_kernel+0x145/0x154 [ 1101.320028] ? secondary_startup_64+0x9f/0x9f [ 1101.320033] Code: 20 04 00 00 eb 9f 4c 89 e7 c6 05 59 44 71 00 01 e8 a7 df fd ff 89 d9 4c 89 e6 48 c7 c7 70 b7 cd 81 48 89 c2 31 c0 e8 97 64 90 ff <0f> ff eb bf 66 66 66 66 2e 0f 1f 84 00 00 00 00 00 0f 1f 44 00 [ 1101.320103] ---[ end trace 0cc4d251e2b57080 ]--- [ 1101.320110] ipheth 1-5:4.2: ipheth_tx_timeout: TX timeout The last message "TX timeout" is repeated every 5 seconds until trust is established or the device is disconnected, filling up dmesg. The proposed patch eliminates the problem by, upon connection, keeping the TX queue and carrier disabled until a packet is first received from the iOS device. This is reflected by the confirmed_pairing variable in the device structure. Only after at least one packet has been received from the iOS device, the transmit queue and carrier are brought up during the periodic device poll in ipheth_carrier_set. Because the iOS device will always send a packet immediately upon trust being established, this should not delay the interface becoming useable. To prevent failed UBRs in ipheth_rcvbulk_callback from perpetually re-enabling the queue if it was disabled, a new check is added so only successful transfers re-enable the queue, whereas failed transfers only trigger an immediate poll. This has the added benefit of removing the periodic control requests to the iOS device until trust has been established and thus should reduce wakeup events on both the host and the iOS device.

Pull GPIO updates from Linus Walleij: "This is the bulk of GPIO changes for the v4.15 kernel cycle: Core: - Fix the semantics of raw GPIO to actually be raw. No inversion semantics as before, but also no open draining, and allow the raw operations to affect lines used for interrupts as the caller supposedly knows what they are doing if they are getting the big hammer. - Rewrote the __inner_function() notation calls to names that make more sense. I just find this kind of code disturbing. - Drop the .irq_base() field from the gpiochip since now all IRQs are mapped dynamically. This is nice. - Support for .get_multiple() in the core driver API. This allows us to read several GPIO lines with a single register read. This has high value for some usecases: it can be used to create oscilloscopes and signal analyzers and other things that rely on reading several lines at exactly the same instant. Also a generally nice optimization. This uses the new assign_bit() macro from the bitops lib that was ACKed by Andrew Morton and is implemented for two drivers, one of them being the generic MMIO driver so everyone using that will be able to benefit from this. - Do not allow requests of Open Drain and Open Source setting of a GPIO line simultaneously. If the hardware actually supports enabling both at the same time the electrical result would be disastrous. - A new interrupt chip core helper. This will be helpful to deal with "banked" GPIOs, which means GPIO controllers with several logical blocks of GPIO inside them. This is several gpiochips per device in the device model, in contrast to the case when there is a 1-to-1 relationship between a device and a gpiochip. New drivers: - Maxim MAX3191x industrial serializer, a very interesting piece of professional I/O hardware. - Uniphier GPIO driver. This is the GPIO block from the recent Socionext (ex Fujitsu and Panasonic) platform. - Tegra 186 driver. This is based on the new banked GPIO infrastructure. Other improvements: - Some documentation improvements. - Wakeup support for the DesignWare DWAPB GPIO controller. - Reset line support on the DesignWare DWAPB GPIO controller. - Several non-critical bug fixes and improvements for the Broadcom BRCMSTB driver. - Misc non-critical bug fixes like exotic errorpaths, removal of dead code etc. - Explicit comments on fall-through switch() statements" * tag 'gpio-v4.15-1' of ssh://gitolite.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio: (65 commits) gpio: tegra186: Remove tegra186_gpio_lock_class gpio: rcar: Add r8a77995 (R-Car D3) support pinctrl: bcm2835: Fix some merge fallout gpio: Fix undefined lock_dep_class gpio: Automatically add lockdep keys gpio: Introduce struct gpio_irq_chip.first gpio: Disambiguate struct gpio_irq_chip.nested gpio: Add Tegra186 support gpio: Export gpiochip_irq_{map,unmap}() gpio: Implement tighter IRQ chip integration gpio: Move lock_key into struct gpio_irq_chip gpio: Move irq_valid_mask into struct gpio_irq_chip gpio: Move irq_nested into struct gpio_irq_chip gpio: Move irq_chained_parent to struct gpio_irq_chip gpio: Move irq_default_type to struct gpio_irq_chip gpio: Move irq_handler to struct gpio_irq_chip gpio: Move irqdomain into struct gpio_irq_chip gpio: Move irqchip into struct gpio_irq_chip gpio: Introduce struct gpio_irq_chip pinctrl: armada-37xx: remove unused variable ...

Now that dax_flush() is no longer a driver callback (commit c3ca015fab6d "dax: remove the pmem_dax_ops->flush abstraction"), stop requiring the dax_read_lock() to be held and the device to be alive.

2017-11-14brd: remove dax supportDan Williams2-77/+0
DAX support in brd is awkward because its backing page frames are distinct from the ones provided by pmem, dcssblk, or axonram. We need pfn_t_devmap() entries to fully support DAX, and the limited DAX support for pfn_t_special() page frames is not interesting for brd when pmem is already a superset of brd. Lastly, brd is the only dax capable driver that may sleep in its ->direct_access() implementation. So it causes a global burden with no net gain of kernel functionality. For all these reasons, remove DAX support.

The vhost_vsock->guest_cid field is uninitialized when /dev/vhost-vsock is opened until the VHOST_VSOCK_SET_GUEST_CID ioctl is called. kvmalloc(..., GFP_KERNEL | __GFP_RETRY_MAYFAIL) does not zero memory. All other vhost_vsock fields are initialized explicitly so just initialize this field too. Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com> Signed-off-by: Michael S. Tsirkin <mst@redhat.com>
2017-11-14vhost: fix end of range for access_okMichael S. Tsirkin1-2/+2
During access_ok checks, addr increases as we iterate over the data structure, thus addr + len - 1 will point beyond the end of region we are translating. Harmless since we then verify that the region covers addr, but let's not waste cpu cycles. Reported-by: Koichiro Den <den@klaipeden.com> Signed-off-by: Michael S.

2017-11-14virtio_balloon: fix deadlock on OOMMichael S. Tsirkin1-5/+19
fill_balloon doing memory allocations under balloon_lock can cause a deadlock when leak_balloon is called from virtballoon_oom_notify and tries to take same lock. To fix, split page allocation and enqueue and do allocations outside the lock. Here's a detailed analysis of the deadlock by Tetsuo Handa: In leak_balloon(), mutex_lock(&vb->balloon_lock) is called in order to serialize against fill_balloon(). But in fill_balloon(), alloc_page(GFP_HIGHUSER[_MOVABLE] | __GFP_NOMEMALLOC | __GFP_NORETRY) is called with vb->balloon_lock mutex held. Since GFP_HIGHUSER[_MOVABLE] implies __GFP_DIRECT_RECLAIM | __GFP_IO | __GFP_FS, despite __GFP_NORETRY is specified, this allocation attempt might indirectly depend on somebody else's __GFP_DIRECT_RECLAIM memory allocation. And such indirect __GFP_DIRECT_RECLAIM memory allocation might call leak_balloon() via virtballoon_oom_notify() via blocking_notifier_call_chain() callback via out_of_memory() when it reached __alloc_pages_may_oom() and held oom_lock mutex. Since vb->balloon_lock mutex is already held by fill_balloon(), it will cause OOM lockup. Thread1 Thread2 fill_balloon() takes a balloon_lock balloon_page_enqueue() alloc_page(GFP_HIGHUSER_MOVABLE) direct reclaim (__GFP_FS context) takes a fs lock waits for that fs lock alloc_page(GFP_NOFS) __alloc_pages_may_oom() takes the oom_lock out_of_memory() blocking_notifier_call_chain() leak_balloon() tries to take that balloon_lock and deadlocks Reported-by: Tetsuo Handa <penguin-kernel@I-love.SAKURA.ne.jp> Cc: Michal Hocko <mhocko@suse.com> Cc: Wei Wang <wei.w.wang@intel.com> Signed-off-by: Michael S.
