I noticed that apic test from kvm-unit-tests always hangs on my EPYC 7401P, the hanging test nmi-after-sti is trying to deliver 30000 NMIs and tracing shows that we're sometimes able to deliver a few but never all. When we're trying to inject an NMI we may fail to do so immediately for various reasons, however, we still need to inject it so enable_nmi_window() arms nmi_singlestep mode. #DB occurs as expected, but we're not checking for pending NMIs before entering the guest and unless there's a different event to process, the NMI will never get delivered. Make KVM_REQ_EVENT request on the vCPU from db_interception() to make sure pending NMIs are checked and possibly injected. Signed-off-by:

This reverts commit bb218fbc. As Oren Twaig pointed out the old discussion: https://patchwork.kernel.org/patch/8292231/ that the change coud potentially cause an extra IPI to be sent to the destination vcpu because the AVIC hardware already set the IRR bit before the incomplete IPI #VMEXIT with id=1 (target vcpu is not running). Since writting to ICR and ICR2 will also set the IRR. If something triggers the destination vcpu to get scheduled before the emulation finishes, then this could result in an additional IPI. Also, the issue mentioned in the commit bb218fbc was misdiagnosed. Cc: Radim Krčmář <rkrcmar@redhat.com> Cc: Paolo Bonzini <pbonzini@redhat.com> Reported-by:

KVM bases its memory usage limits on the total number of guest pages across all memslots. However, those limits, and the calculations to produce them, use 32 bit unsigned integers. This can result in overflow if a VM has more guest pages that can be represented by a u32. As a result of this overflow, KVM can use a low limit on the number of MMU pages it will allocate. This makes KVM unable to map all of guest memory at once, prompting spurious faults. Tested: Ran all kvm-unit-tests on an Intel Haswell machine. This patch introduced no new failures. Signed-off-by:

The remaining failures of vmx.flat when EPT is disabled are caused by incorrectly reflecting VMfails to the L1 hypervisor. What happens is that nested_vmx_restore_host_state corrupts the guest CR3, reloading it with the host's shadow CR3 instead, because it blindly loads GUEST_CR3 from the vmcs01. For simplicity let's just always use hardware VMCS checks when EPT is disabled. This way, nested_vmx_restore_host_state is not reached at all (or at least shouldn't be reached). Signed-off-by:

Badly-designed systems might have (for example) active-high wake pins that default to high (e.g., because of external pull ups) until they have an active firmware which starts driving it low. This can cause an interrupt storm in the time between request_irq() and disable_irq(). We don't support shared interrupts here, so let's just pre-configure the interrupt to avoid auto-enabling it.

There is logic to check that the RX/TPA consumer index is the expected index to work around a hardware problem. However, the potentially bad consumer index is first used to index into an array to reference an entry. This can potentially crash if the bad consumer index is beyond legal range.

Michael Zhivich says: ==================== ethtool: fix use of SPEED_UNKNOWN constant This patch series addresses 2 related issues: 1. ethtool_validate_speed() triggers a "signed-unsigned comparison" warning due to type difference of SPEED_UNKNOWN constant (int) and argument to ethtool_validate_speed (__u32). 2. some drivers use u16 storage for SPEED_UNKNOWN constant, resulting in value truncation and thus failure to test against SPEED_UNKNOWN correctly.

The poll condition should only check response_length, because reads should only be issued if there is data to read. The response_read flag only prevents double writes. The problem was that the write set the response_read to false, enqued a tpm job, and returned. Then application called poll which checked the response_read flag and returned EPOLLIN. Then the application called read, but got nothing. After all that the async_work kicked in. Added also mutex_lock around the poll check to prevent other possible race conditions.

There's a significant number of reports that re-enabling ASPM causes different issues, ranging from decreased performance to system not booting at all. This affects only a minority of users, but the number of affected users is big enough that we better switch off ASPM again. This will hurt notebook users who are not affected by the issues, they may see decreased battery runtime w/o ASPM. With the PCI core folks is being discussed to add generic sysfs attributes to control ASPM. Once this is in place brave enough users can re-enable ASPM on their system.

When the mtu of a vrf device is set to 0, it would cause ping failed. So I think we should limit vrf mtu in a reasonable range to solve this problem. I set dev->min_mtu to IPV6_MIN_MTU, so it will works for both ipv4 and ipv6. And if dev->max_mtu still be 0 can be confusing, so I set dev->max_mtu to ETH_MAX_MTU. Here is the reproduce step: 1.Config vrf interface and set mtu to 0: 3: enp4s0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel master vrf1 state UP mode DEFAULT group default qlen 1000 link/ether 52:54:00:9e:dd:c1 brd ff:ff:ff:ff:ff:ff 2.Ping peer: 3: enp4s0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel master vrf1 state UP group default qlen 1000 link/ether 52:54:00:9e:dd:c1 brd ff:ff:ff:ff:ff:ff inet 10.0.0.1/16 scope global enp4s0 valid_lft forever preferred_lft forever connect: Network is unreachable 3.Set mtu to default value, ping works: PING 10.0.0.2 (10.0.0.2) 56(84) bytes of data. 64 bytes from 10.0.0.2: icmp_seq=1 ttl=64 time=1.88 ms Fixes: ad49bc63 ("net: vrf: remove MTU limits for vrf device") Signed-off-by:
