[PATCH v4 2/6] usb: dwc3: gadget: cancel requests instead of release after missed isoc

by Dan Vacura

From: Jeff Vanhoof <qjv001(a)motorola.com> arm-smmu related crashes seen after a Missed ISOC interrupt when no_interrupt=1 is used. This can happen if the hardware is still using the data associated with a TRB after the usb_request's ->complete call has been made. Instead of immediately releasing a request when a Missed ISOC interrupt has occurred, this change will add logic to cancel the request instead where it will eventually be released when the END_TRANSFER command has completed. This logic is similar to some of the cleanup done in dwc3_gadget_ep_dequeue.

[PATCH] ACPI: APEI: set memory failure flags as MF_ACTION_REQUIRED on action required events

by Shuai Xue

There are two major types of uncorrected error (UC) : - Action Required: The error is detected and the processor already consumes the memory. OS requires to take action (for example, offline failure page/kill failure thread) to recover this uncorrectable error. - Action Optional: The error is detected out of processor execution context. Some data in the memory are corrupted. But the data have not been consumed. OS is optional to take action to recover this uncorrectable error. For X86 platforms, we can easily distinguish between these two types based on the MCA Bank. While for arm64 platform, the memory failure flags for all UCs which severity are GHES_SEV_RECOVERABLE are set as 0, a.k.a, Action Optional now. If UC is detected by a background scrubber, it is obviously an Action Optional error. For other errors, we should conservatively regard them as Action Required. cper_sec_mem_err::error_type identifies the type of error that occurred if CPER_MEM_VALID_ERROR_TYPE is set. So, set memory failure flags as 0 for Scrub Uncorrected Error (type 14). Otherwise, set memory failure flags as MF_ACTION_REQUIRED.

[PATCH] iio: afe: rescale: Fix logic bug

by Linus Walleij

When introducing support for processed channels I needed to invert the expression: if (!iio_channel_has_info(schan, IIO_CHAN_INFO_RAW) || !iio_channel_has_info(schan, IIO_CHAN_INFO_SCALE)) dev_err(dev, "source channel does not support raw/scale\n"); To the inverse, meaning detect when we can usse raw+scale rather than when we can not. This was the result: if (iio_channel_has_info(schan, IIO_CHAN_INFO_RAW) || iio_channel_has_info(schan, IIO_CHAN_INFO_SCALE)) dev_info(dev, "using raw+scale source channel\n"); Ooops. Spot the error. Yep old George Boole came up and bit me. That should be an &&. The current code "mostly works" because we have not run into systems supporting only raw but not scale or only scale but not raw, and I doubt there are few using the rescaler on anything such, but let's fix the logic.

[PATCH 1/1] tpm: disable hwrng for fTPM on some AMD designs

by Mario Limonciello

AMD has issued an advisory indicating that having fTPM enabled in BIOS can cause "stuttering" in the OS. This issue has been fixed in newer versions of the fTPM firmware, but it's up to system designers to decide whether to distribute it. This issue has existed for a while, but is more prevalent starting with kernel 6.1 because commit b006c439d58db ("hwrng: core - start hwrng kthread also for untrusted sources") started to use the fTPM for hwrng by default. However, all uses of /dev/hwrng result in unacceptable stuttering. So, simply disable registration of the defective hwrng when detecting these faulty fTPM versions.

[PATCH 2/3] acpi/processor: sanitize _PDC buffer bits when running as Xen dom0

by Roger Pau Monne

The Processor _PDC buffer bits notify ACPI of the OS capabilities, and so ACPI can adjust the return of other Processor methods taking the OS capabilities into account. When Linux is running as a Xen dom0, it's the hypervisor the entity in charge of processor power management, and hence Xen needs to make sure the capabilities reported in the _PDC buffer match the capabilities of the driver in Xen. Introduce a small helper to sanitize the buffer when running as Xen dom0.

[PATCH] ext4: Fix possible corruption when moving a directory

by Jan Kara

When we are renaming a directory to a different directory, we need to update '..' entry in the moved directory. However nothing prevents moved directory from being modified and even converted from the inline format to the normal format. When such race happens the rename code gets confused and we crash. Fix the problem by locking the moved directory.

[PATCH 1/1] net: cdc_ncm: Allow for dwNtbOutMaxSize to be unset or zero

by Lee Jones

Currently, due to the sequential use of min_t() and clamp_t() macros, in cdc_ncm_check_tx_max(), if dwNtbOutMaxSize is not set, the logic sets tx_max to 0. This is then used to allocate the data area of the SKB requested later in cdc_ncm_fill_tx_frame(). This does not cause an issue presently because when memory is allocated during initialisation phase of SKB creation, more memory (512b) is allocated than is required for the SKB headers alone (320b), leaving some space (512b - 320b = 192b) for CDC data (172b). However, if more elements (for example 3 x u64 = [24b]) were added to one of the SKB header structs, say 'struct skb_shared_info', increasing its original size (320b [320b aligned]) to something larger (344b [384b aligned]), then suddenly the CDC data (172b) no longer fits in the spare SKB data area (512b - 384b = 128b). Consequently the SKB bounds checking semantics fails and panics: skbuff: skb_over_panic: text:ffffffff830a5b5f len:184 put:172 \ head:ffff888119227c00 data:ffff888119227c00 tail:0xb8 end:0x80 dev:<NULL> ------------[ cut here ]------------ kernel BUG at net/core/skbuff.c:110!

[PATCH 0/9] KVM backports to 5.10

by Rishabh Bhatnagar

This patch series backports a few VM preemption_status, steal_time and PV TLB flushing fixes to 5.10 stable kernel. Most of the changes backport cleanly except i had to work around a few becauseof missing support/APIs in 5.10 kernel. I have captured those in the changelog as well in the individual patches. Changelog - Use mark_page_dirty_in_slot api without kvm argument (KVM: x86: Fix recording of guest steal time / preempted status) - Avoid checking for xen_msr and SEV-ES conditions (KVM: x86: do not set st->preempted when going back to user space) - Use VCPU_STAT macro to expose preemption_reported and preemption_other fields (KVM: x86: do not report a vCPU as preempted outside instruction boundaries) David Woodhouse (2): KVM: x86: Fix recording of guest steal time / preempted status KVM: Fix steal time asm constraints Lai Jiangshan (1): KVM: x86: Ensure PV TLB flush tracepoint reflects KVM behavior Paolo Bonzini (5): KVM: x86: do not set st->preempted when going back to user space KVM: x86: do not report a vCPU as preempted outside instruction boundaries KVM: x86: revalidate steal time cache if MSR value changes KVM: x86: do not report preemption if the steal time cache is stale KVM: x86: move guest_pv_has out of user_access section Sean Christopherson (1): KVM: x86: Remove obsolete disabling of page faults in kvm_arch_vcpu_put() arch/x86/include/asm/kvm_host.h | 5 +- arch/x86/kvm/svm/svm.c | 2 + arch/x86/kvm/vmx/vmx.c | 1 + arch/x86/kvm/x86.c | 164 ++++++++++++++++++++++---------- 4 files changed, 122 insertions(+), 50 deletions(-) -- 2.37.1
