Donenfeld" <Jason(a)zx2c4.com> Date: Thu, 28 Jul 2022 00:32:18 +1000 Subject: [PATCH] powerpc/powernv/kvm: Use darn for H_RANDOM on Power9 The existing logic in KVM to support guests calling H_RANDOM only works on Power8, because it looks for an RNG in the device tree, but on Power9 we just use darn. In addition the existing code needs to work in real mode, so we have the special cased powernv_get_random_real_mode() to deal with that. Instead just have KVM call ppc_md.get_random_seed(), and do the real mode check inside of there, that way we use whatever RNG is available, including darn on Power9.

[PATCH AUTOSEL 5.19 001/105] fbdev: Restart conflicting fb removal loop when unregistering devices

by Sasha Levin

From: Javier Martinez Canillas <javierm(a)redhat.com> [ Upstream commit 3367aa7d74d240261de2543ddb35531ccad9d884 ] Drivers that want to remove registered conflicting framebuffers prior to register their own framebuffer, call to remove_conflicting_framebuffers(). This function takes the registration_lock mutex, to prevent a race when drivers register framebuffer devices. But if a conflicting framebuffer device is found, the underlaying platform device is unregistered and this will lead to the platform driver .remove callback to be called. Which in turn will call to unregister_framebuffer() that takes the same lock. To prevent this, a struct fb_info.forced_out field was used as indication to unregister_framebuffer() whether the mutex has to be grabbed or not. But this could be unsafe, since the fbdev core is making assumptions about what drivers may or may not do in their .remove callbacks. Allowing to run these callbacks with the registration_lock held can cause deadlocks, since the fbdev core has no control over what drivers do in their removal path. A better solution is to drop the lock before platform_device_unregister(), so unregister_framebuffer() can take it when called from the fbdev driver. The lock is acquired again after the device has been unregistered and at this point the removal loop can be restarted. Since the conflicting framebuffer device has already been removed, the loop would just finish when no more conflicting framebuffers are found.

FAILED: patch "[PATCH] KVM: nVMX: Snapshot pre-VM-Enter DEBUGCTL for" failed to apply to 4.19-stable tree

by gregkh＠linuxfoundation.org

The patch below does not apply to the 4.19-stable tree. If someone wants it applied there, or to any other stable or longterm tree, then please email the backport, including the original git commit id to <stable(a)vger.kernel.org>. thanks, greg k-h ------------------ original commit in Linus's tree ------------------ From 764643a6be07445308e492a528197044c801b3ba Mon Sep 17 00:00:00 2001 From: Sean Christopherson <seanjc(a)google.com> Date: Tue, 14 Jun 2022 21:58:28 +0000 Subject: [PATCH] KVM: nVMX: Snapshot pre-VM-Enter DEBUGCTL for !nested_run_pending case If a nested run isn't pending, snapshot vmcs01.GUEST_IA32_DEBUGCTL irrespective of whether or not VM_ENTRY_LOAD_DEBUG_CONTROLS is set in vmcs12. When restoring nested state, e.g. after migration, without a nested run pending, prepare_vmcs02() will propagate nested.vmcs01_debugctl to vmcs02, i.e. will load garbage/zeros into vmcs02.GUEST_IA32_DEBUGCTL. If userspace restores nested state before MSRs, then loading garbage is a non-issue as loading DEBUGCTL will also update vmcs02. But if usersepace restores MSRs first, then KVM is responsible for propagating L2's value, which is actually thrown into vmcs01, into vmcs02. Restoring L2 MSRs into vmcs01, i.e. loading all MSRs before nested state is all kinds of bizarre and ideally would not be supported. Sadly, some VMMs do exactly that and rely on KVM to make things work. Note, there's still a lurking SMM bug, as propagating vmcs01's DEBUGCTL to vmcs02 across RSM may corrupt L2's DEBUGCTL. But KVM's entire VMX+SMM emulation is flawed as SMI+RSM should not toouch _any_ VMCS when use the "default treatment of SMIs", i.e. when not using an SMI Transfer Monitor.
