[PATCH] KVM: vmx, svm: always run with EFER.NXE=1 when shadow paging is active

by Paolo Bonzini

VMX already does so if the host has SMEP, in order to support the combination of CR0.WP=1 and CR4.SMEP=1. However, it is perfectly safe to always do so, and in fact VMX already ends up running with EFER.NXE=1 on old processors that lack the "load EFER" controls, because it may help avoiding a slow MSR write. Removing all the conditionals simplifies the code. SVM does not have similar code, but it should since recent AMD processors do support SMEP. So this patch also makes the code for the two vendors more similar while fixing NPT=0, CR0.WP=1 and CR4.SMEP=1 on AMD processors.

[PATCH AUTOSEL 5.3 01/89] iio: adc: meson_saradc: Fix memory allocation order

by Sasha Levin

From: Remi Pommarel <repk(a)triplefau.lt> [ Upstream commit de10ac47597e7a3596b27631d0d5ce5f48d2c099 ] meson_saradc's irq handler uses priv->regmap so make sure that it is allocated before the irq get enabled. This also fixes crash when CONFIG_DEBUG_SHIRQ is enabled, as device managed resources are freed in the inverted order they had been allocated, priv->regmap was freed before the spurious fake irq that CONFIG_DEBUG_SHIRQ adds called the handler.

patch "USB: gadget: Reject endpoints with 0 maxpacket value" added to usb-linus

by gregkh＠linuxfoundation.org

This is a note to let you know that I've just added the patch titled USB: gadget: Reject endpoints with 0 maxpacket value to my usb git tree which can be found at git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb.git in the usb-linus branch. The patch will show up in the next release of the linux-next tree (usually sometime within the next 24 hours during the week.) The patch will hopefully also be merged in Linus's tree for the next -rc kernel release. If you have any questions about this process, please let me know. >From 54f83b8c8ea9b22082a496deadf90447a326954e Mon Sep 17 00:00:00 2001 From: Alan Stern <stern(a)rowland.harvard.edu> Date: Mon, 28 Oct 2019 10:54:26 -0400 Subject: USB: gadget: Reject endpoints with 0 maxpacket value Endpoints with a maxpacket length of 0 are probably useless. They can't transfer any data, and it's not at all unlikely that a UDC will crash or hang when trying to handle a non-zero-length usb_request for such an endpoint. Indeed, dummy-hcd gets a divide error when trying to calculate the remainder of a transfer length by the maxpacket value, as discovered by the syzbot fuzzer. Currently the gadget core does not check for endpoints having a maxpacket value of 0. This patch adds a check to usb_ep_enable(), preventing such endpoints from being used. As far as I know, none of the gadget drivers in the kernel tries to create an endpoint with maxpacket = 0, but until now there has been nothing to prevent userspace programs under gadgetfs or configfs from doing it.

Overall result: FAILED (see details below) Merge: OK Compile: OK Tests: FAILED All kernel binaries, config files, and logs are available for download here: https://artifacts.cki-project.org/pipelines/251766 One or more kernel tests failed: ppc64le: ❌ xfstests: ext4 ❌ xfstests: xfs aarch64: ❌ xfstests: ext4 ❌ xfstests: xfs x86_64: ❌ Memory function: kaslr ❌ xfstests: ext4 ❌ xfstests: xfs We hope that these logs can help you find the problem quickly. For the full detail on our testing procedures, please scroll to the bottom of this message. Please reply to this email if you have any questions about the tests that we ran or if you have any suggestions on how to make future tests more effective. ,-. ,-.

Waived tests ------------ If the test run included waived tests, they are marked with 🚧. Such tests are executed but their results are not taken into account. Tests are waived when their results are not reliable enough, e.g. when they're just introduced or are being fixed. Testing timeout --------------- We aim to provide a report within reasonable timeframe. Tests that haven't finished running are marked with ⏱. Reports for non-upstream kernels have a Beaker recipe linked to next to each host.
