2020-03-01KVM: VMX: check descriptor table exits on instruction emulationOliver Upton1-0/+15
KVM emulates UMIP on hardware that doesn't support it by setting the 'descriptor table exiting' VM-execution control and performing instruction emulation. When running nested, this emulation is broken as KVM refuses to emulate L2 instructions by default. Correct this regression by allowing the emulation of descriptor table instructions if L1 hasn't requested 'descriptor table exiting'.

2020-02-29ext4: potential crash on allocation error in ext4_alloc_flex_bg_array()Dan Carpenter1-3/+3
If sbi->s_flex_groups_allocated is zero and the first allocation fails then this code will crash. The problem is that "i--" will set "i" to -1 but when we compare "i >= sbi->s_flex_groups_allocated" then the -1 is type promoted to unsigned and becomes UINT_MAX. Since UINT_MAX is more than zero, the condition is true so we call kvfree(new_groups[-1]). The loop will carry on freeing invalid memory until it crashes.

2020-02-29macintosh: therm_windtunnel: fix regression when instantiating devicesWolfram Sang1-21/+31
Removing attach_adapter from this driver caused a regression for at least some machines. Those machines had the sensors described in their DT, too, so they didn't need manual creation of the sensor devices. The old code worked, though, because manual creation came first. Creation of DT devices then failed later and caused error logs, but the sensors worked nonetheless because of the manually created devices. When removing attach_adaper, manual creation now comes later and loses the race. The sensor devices were already registered via DT, yet with another binding, so the driver could not be bound to it. This fix refactors the code to remove the race and only manually creates devices if there are no DT nodes present. Also, the DT binding is updated to match both, the DT and manually created devices. Because we don't know which device creation will be used at runtime, the code to start the kthread is moved to do_probe() which will be called by both methods.

2020-02-28kvm: x86: Limit the number of "kvm: disabled by bios" messagesErwan Velu1-2/+2
In older version of systemd(219), at boot time, udevadm is called with : /usr/bin/udevadm trigger --type=devices --action=add" This program generates an echo "add" in /sys/devices/system/cpu/cpu<x>/uevent, leading to the "kvm: disabled by bios" message in case of your Bios disabled the virtualization extensions. On a modern system running up to 256 CPU threads, this pollutes the Kernel logs. This patch offers to ratelimit this message to avoid any userspace program triggering this uevent printing this message too often. This patch is only a workaround but greatly reduce the pollution without breaking the current behavior of printing a message if some try to instantiate KVM on a system that doesn't support it. Note that recent versions of systemd (>239) do not have trigger this behavior. This patch will be useful at least for some using older systemd with recent Kernels.

2020-02-27io_uring: fix 32-bit compatability with sendmsg/recvmsgJens Axboe1-0/+10
We must set MSG_CMSG_COMPAT if we're in compatability mode, otherwise the iovec import for these commands will not do the right thing and fail the command with -EINVAL. Found by running the test suite compiled as 32-bit.

2020-02-27mlxsw: pci: Wait longer before accessing the device after resetAmit Cohen1-1/+1
During initialization the driver issues a reset to the device and waits for 100ms before checking if the firmware is ready. The waiting is necessary because before that the device is irresponsive and the first read can result in a completion timeout. While 100ms is sufficient for Spectrum-1 and Spectrum-2, it is insufficient for Spectrum-3. Fix this by increasing the timeout to 200ms.

2020-02-27sfc: fix timestamp reconstruction at 16-bit rollover pointsAlex Maftei (amaftei)1-3/+35
We can't just use the top bits of the last sync event as they could be off-by-one every 65,536 seconds, giving an error in reconstruction of 65,536 seconds. This patch uses the difference in the bottom 16 bits (mod 2^16) to calculate an offset that needs to be applied to the last sync event to get to the current time.
