Another patch by me for the mcp251xfd driver add sanity checking to bail out if no IRQ is configured. The next three patches target the m_can driver. A patch by me removes the hardcoded IRQF_TRIGGER_FALLING from the request_threaded_irq() as this clashes with the trigger level specified in the DT. Further a patch by me fixes the nominal bitiming tseg2 min value for modern m_can cores. Pankaj Sharma's patch add support for cores version 3.3.x. The last patch by Oliver Hartkopp is for af_can and converts a WARN() into a pr_warn(), which is triggered by the syzkaller. It was able to create a situation where the closing of a socket runs simultaneously to the notifier call chain for removing the CAN network device in use. * tag 'linux-can-fixes-for-5.10-20201127' of git://git.kernel.org/pub/scm/linux/kernel/git/mkl/linux-can: can: af_can: can_rx_unregister(): remove WARN() statement from list operation sanity check can: m_can: m_can_dev_setup(): add support for bosch mcan version 3.3.0 can: m_can: fix nominal bitiming tseg2 min for version >= 3.1 can: m_can: m_can_open(): remove IRQF_TRIGGER_FALLING from request_threaded_irq()'s flags can: mcp251xfd: mcp251xfd_probe(): bail out if no IRQ was given can: gs_usb: fix endianess problem with candleLight firmware ==================== Link: https://lore.kernel.org/r/20201127100301.512603-1-mkl@pengutronix.de Signed-off-by: Jakub Kicinski <kuba@kernel.org> 27 November 2020, 19:13:39 UTC

d3ab788 Paolo Abeni 26 November 2020, 14:17:53 UTC mptcp: fix NULL ptr dereference on bad MPJ If an msk listener receives an MPJ carrying an invalid token, it will zero the request socket msk entry. That should later cause fallback and subflow reset - as per RFC - at subflow_syn_recv_sock() time due to failing hmac validation. Since commit 4cf8b7e48a09 ("subflow: introduce and use mptcp_can_accept_new_subflow()"), we unconditionally dereference - in mptcp_can_accept_new_subflow - the subflow request msk before performing hmac validation. In the above scenario we hit a NULL ptr dereference. Address the issue doing the hmac validation earlier.

69929d4 Eelco Chaudron 24 November 2020, 12:34:44 UTC net: openvswitch: fix TTL decrement action netlink message format Currently, the openvswitch module is not accepting the correctly formated netlink message for the TTL decrement action. For both setting and getting the dec_ttl action, the actions should be nested in the OVS_DEC_TTL_ATTR_ACTION attribute as mentioned in the openvswitch.h uapi. When the original patch was sent, it was tested with a private OVS userspace implementation. This implementation was unfortunately not upstreamed and reviewed, hence an erroneous version of this patch was sent out. Leaving the patch as-is would cause problems as the kernel module could interpret additional attributes as actions and vice-versa, due to the actions not being encapsulated/nested within the actual attribute, but being concatinated after it.

Note, this happens with the traditional MMU and EPT enabled, not with the newly introduced TDP MMU. Turns out, there was a subtle change in the above mentioned commit. Previously, walk_shadow_page_get_mmio_spte() was setting 'root' to 'iterator.level' which is returned by shadow_walk_init() and this equals to 'vcpu->arch.mmu->shadow_root_level'. Now, get_mmio_spte() sets it to 'int root = vcpu->arch.mmu->root_level'. The difference between 'root_level' and 'shadow_root_level' on CPUs supporting 5-level page tables is that in some case we don't want to use 5-level, in particular when 'cpuid_maxphyaddr(vcpu) <= 48' kvm_mmu_get_tdp_level() returns '4'.

71cc849 Paolo Bonzini 27 November 2020, 08:18:20 UTC KVM: x86: Fix split-irqchip vs interrupt injection window request kvm_cpu_accept_dm_intr and kvm_vcpu_ready_for_interrupt_injection are a hodge-podge of conditions, hacked together to get something that more or less works. But what is actually needed is much simpler; in both cases the fundamental question is, do we have a place to stash an interrupt if userspace does KVM_INTERRUPT? In userspace irqchip mode, that is !vcpu->arch.interrupt.injected. Currently kvm_event_needs_reinjection(vcpu) covers it, but it is unnecessarily restrictive. In split irqchip mode it's a bit more complicated, we need to check kvm_apic_accept_pic_intr(vcpu) (the IRQ window exit is basically an INTACK cycle and thus requires ExtINTs not to be masked) as well as !pending_userspace_extint(vcpu). However, there is no need to check kvm_event_needs_reinjection(vcpu), since split irqchip keeps pending ExtINT state separate from event injection state, and checking kvm_cpu_has_interrupt(vcpu) is wrong too since ExtINT has higher priority than APIC interrupts. In fact the latter fixes a bug: when userspace requests an IRQ window vmexit, an interrupt in the local APIC can cause kvm_cpu_has_interrupt() to be true and thus kvm_vcpu_ready_for_interrupt_injection() to return false. When this happens, vcpu_run does not exit to userspace but the interrupt window vmexits keep occurring. The VM loops without any hope of making progress. Once we try to fix these with something like return kvm_arch_interrupt_allowed(vcpu) && - !kvm_cpu_has_interrupt(vcpu) && - !kvm_event_needs_reinjection(vcpu) && - kvm_cpu_accept_dm_intr(vcpu); + (!lapic_in_kernel(vcpu) + ? !vcpu->arch.interrupt.injected + : (kvm_apic_accept_pic_intr(vcpu) + && !pending_userspace_extint(v))); we realize two things. First, thanks to the previous patch the complex conditional can reuse !kvm_cpu_has_extint(vcpu). Second, the interrupt window request in vcpu_enter_guest() bool req_int_win = dm_request_for_irq_injection(vcpu) && kvm_cpu_accept_dm_intr(vcpu); should be kept in sync with kvm_vcpu_ready_for_interrupt_injection(): it is unnecessary to ask the processor for an interrupt window if we would not be able to return to userspace. Therefore, kvm_cpu_accept_dm_intr(vcpu) is basically !kvm_cpu_has_extint(vcpu) ANDed with the existing check for masked ExtINT. It all makes sense: - we can accept an interrupt from userspace if there is a place to stash it (and, for irqchip split, ExtINTs are not masked). Interrupts from userspace _can_ be accepted even if right now EFLAGS.IF=0. - in order to tell userspace we will inject its interrupt ("IRQ window open" i.e. kvm_vcpu_ready_for_interrupt_injection), both KVM and the vCPU need to be ready to accept the interrupt. ... and this is what the patch implements.

This removes duplicated code from kvm_cpu_has_injectable_intr and kvm_cpu_has_interrupt, and makes the code more similar between kvm_cpu_has_{extint,interrupt} on one side and kvm_cpu_get_{extint,interrupt} on the other.

Initially we thought it was due to the cache alignment change introduced by the patch, but further debug shows that it is due to some hot data members ('vmstats_local', 'vmstats_percpu', 'vmstats') sit in 2 adjacent cacheline (2N and 2N+1 cacheline), and when adjacent cache line prefetch is enabled, it triggers an "extended level" of cache false sharing for 2 adjacent cache lines. So exchange the 2 member blocks, while keeping mostly the original cache alignment, which can restore and even enhance the performance, and save 64 bytes of space for 'struct mem_cgroup' (from 2880 to 2816, with 0day's default RHEL-8.3 kernel config) [1]. https://lore.kernel.org/lkml/20201102091543.GM31092@shao2-debian/ Fixes: bd0b230fe145 ("mm/memcg: unify swap and memsw page counters") Reported-by: kernel test robot <rong.a.chen@intel.com> Signed-off-by: Feng Tang <feng.tang@intel.com> Acked-by: Waiman Long <longman@redhat.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> 26 November 2020, 17:35:49 UTC

f2eae18 Hans de Goede 06 November 2020, 14:01:30 UTC platform/x86: thinkpad_acpi: Do not report SW_TABLET_MODE on Yoga 11e The Yoga 11e series has 2 accelerometers described by a BOSC0200 ACPI node. This setup relies on a Windows service which reads both accelerometers and then calculates the angle between the 2 halves to determine laptop / tent / tablet mode and then reports the calculated mode back to the EC by calling special ACPI methods on the BOSC0200 node. The bmc150 iio driver does not support this (it involves double calculations requiring sqrt and arccos so this really needs to be done in userspace), as a result of this on the Yoga 11e the thinkpad_acpi code always reports SW_TABLET_MODE=0, starting with GNOME 3.38 reporting SW_TABLET_MODE=0 causes GNOME to: 1. Not show the onscreen keyboard when a text-input field is focussed with the touchscreen. 2. Disable accelerometer based auto display-rotation. This makes sense when in laptop-mode but not when in tablet-mode. But since for the Yoga 11e the thinkpad_acpi code always reports SW_TABLET_MODE=0, GNOME does not know when the device is in tablet-mode. Stop reporting the broken (always 0) SW_TABLET_MODE on Yoga 11e models to fix this. Note there are plans for userspace to support 360 degree hinges style 2-in-1s with 2 accelerometers and figure out the mode by itself, see: https://gitlab.freedesktop.org/hadess/iio-sensor-proxy/-/issues/216 Signed-off-by: Hans de Goede <hdegoede@redhat.com> Link: https://lore.kernel.org/r/20201106140130.46820-1-hdegoede@redhat.com 26 November 2020, 14:44:35 UTC

4ba1cb3 Marc Kleine-Budde 19 November 2020, 13:03:17 UTC can: gs_usb: fix endianess problem with candleLight firmware The firmware on the original USB2CAN by Geschwister Schneider Technologie Entwicklungs- und Vertriebs UG exchanges all data between the host and the device in host byte order. This is done with the struct gs_host_config::byte_order member, which is sent first to indicate the desired byte order. The widely used open source firmware candleLight doesn't support this feature and exchanges the data in little endian byte order. This breaks if a device with candleLight firmware is used on big endianess systems. To fix this problem, all u32 (but not the struct gs_host_frame::echo_id, which is a transparent cookie) are converted to __le32.

As the same value is also used for the network ID, the range 0xff01-0xffff also fits better, as values lower than that depend if the network is used for satellite, terrestrial, cable of CI. While here, move the TS ID to the bridge code, where it is used, and change its value, as it was identical to the value previously used by network ID.
