[PATCH OLK-6.6] arm64: lib: improve usercopy performance by mitigating data dependencies
by Li Zetao 16 May '24

16 May '24

hulk inclusion category: performance bugzilla: https://gitee.com/openeuler/kernel/issues/I9PXLD?from=project-issue CVE: NA -------------------------------- In the copy_from/to_user scenario, due to the need to accurately calculate the number of copied bytes for fixup, it is necessary to increment the values of src and dst after each copy of the data. Therefore, this introduce RAW dependency which result in some bubble in pipline and degrade the IPC. Consider updating the values of src and dst only when the copy is completed in the current stage to reduce data dependence. But this will break the function of fixup, so in order to maintain the function of fixup, a new macro USER_OFF is introduced to determine the number of bytes that load/store has completed copying at this stage, the final number of bytes that have not been copied can be determined.

[PATCH OLK-5.10] x86/cpufeatures: Fix dependencies for GFNI, VAES, and VPCLMULQDQ
by Yang Yingliang 16 May '24

16 May '24

From: Eric Biggers <ebiggers(a)google.com> Fix cpuid_deps[] to list the correct dependencies for GFNI, VAES, and VPCLMULQDQ. These features don't depend on AVX512, and there exist CPUs that support these features but not AVX512. GFNI actually doesn't even depend on AVX. This prevents GFNI from being unnecessarily disabled if AVX is disabled to mitigate the GDS vulnerability. This also prevents all three features from being unnecessarily disabled if AVX512VL (or its dependency AVX512F) were to be disabled, but it looks like there isn't any case where this happens anyway.

At this piont, accidentally if usb transport error should happen in usb_ep_enable(), 'in_ep' and/or 'out_ep' may not be enabled. After that, ncm_disable() is called to disable for ncm unbind but gether_disconnect() is never called since 'in_ep' is not enabled. As the result, ncm object is released in ncm unbind but 'dev->port_usb' associated to 'ncm->port' is not NULL. And when ncm bind again to recover netdev, ncm object is reallocated but usb0 interface is already associated to previous released ncm object. Therefore, once usb0 interface is up and eth_start_xmit() is called, released ncm object is dereferrenced and it might cause use-after-free memory.

We only need to send the CMD_SYNC in the granual of the level 3 pagetable block size, this can greatly reduce the amounts of CMD_SYNC times sent to avoiding the errata. Detecting the hardware ability by read the SMMU_USER_CONFIG1. Also, We don't have to send a tlbi before a CMD_SYNC, It will be OK for the hardware to merge the CMD_SYNC.

On CPU hotplug MSR_IA32_XFD is reset to the init_fpstate.xfd, which wipes out any stale state. But the per CPU cached xfd value is not reset, which brings them out of sync. As a consequence a subsequent xfd_update_state() might fail to update the MSR which in turn can result in XRSTOR raising a #NM in kernel space, which crashes the kernel. To fix this, introduce xfd_set_state() to write xfd_state together with MSR_IA32_XFD, and use it in all places that set MSR_IA32_XFD.

We only need to send the CMD_SYNC in the granual of the level 3 pagetable block size, this can greatly reduce the amounts of CMD_SYNC times sent to avoiding the errata. Detecting the hardware ability by read the SMMU_USER_CONFIG1. Also, We don't have to send a tlbi before a CMD_SYNC, It will be OK for the hardware to merge the CMD_SYNC.

[PATCH OLK-5.10] cpu/SMT: Make SMT control more robust against enumeration failures
by Yang Yingliang 16 May '24

16 May '24

From: Thomas Gleixner <tglx(a)linutronix.de> mainline inclusion from mainline-v6.7-rc1 commit d91bdd96b55cc3ce98d883a60f133713821b80a6 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I9NZ3E Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- The SMT control mechanism got added as speculation attack vector mitigation. The implemented logic relies on the primary thread mask to be set up properly. This turns out to be an issue with XEN/PV guests because their CPU hotplug mechanics do not enumerate APICs and therefore the mask is never correctly populated. This went unnoticed so far because by chance XEN/PV ends up with smp_num_siblings == 2. So smt_hotplug_control stays at its default value CPU_SMT_ENABLED and the primary thread mask is never evaluated in the context of CPU hotplug. This stopped "working" with the upcoming overhaul of the topology evaluation which legitimately provides a fake topology for XEN/PV. That sets smp_num_siblings to 1, which causes the core CPU hot-plug core to refuse to bring up the APs. This happens because smt_hotplug_control is set to CPU_SMT_NOT_SUPPORTED which causes cpu_smt_allowed() to evaluate the unpopulated primary thread mask with the conclusion that all non-boot CPUs are not valid to be plugged. Make cpu_smt_allowed() more robust and take CPU_SMT_NOT_SUPPORTED and CPU_SMT_NOT_IMPLEMENTED into account. Rename it to cpu_bootable() while at it as that makes it more clear what the function is about. The primary mask issue on x86 XEN/PV needs to be addressed separately as there are users outside of the CPU hotplug code too.
