2020-10-30KVM: x86: Fix NULL dereference at kvm_msr_ignored_check()Takashi Iwai
The newly introduced kvm_msr_ignored_check() tries to print error or debug messages via vcpu_*() macros, but those may cause Oops when NULL vcpu is passed for KVM_GET_MSRS ioctl. Fix it by replacing the print calls with kvm_*() macros. (Note that this will leave vcpu argument completely unused in the function, but I didn't touch it to make the fix as small as possible. A clean up may be applied later.) Fixes: 12bc2132b15e ("KVM: X86: Do the same ignore_msrs check for feature msrs") BugLink: https://bugzilla.suse.com/show_bug.cgi?id=1178280 Cc: <stable@vger.kernel.org> Signed-off-by: Takashi Iwai <tiwai@suse.de> Message-Id: <20201030151414.20165-1-tiwai@suse.de> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

2020-10-30lockdep: Fix nr_unused_locks accountingPeter Zijlstra
Chris reported that commit 24d5a3bffef1 ("lockdep: Fix usage_traceoverflow") breaks the nr_unused_locks validation code triggered by /proc/lockdep_stats. By fully splitting LOCK_USED and LOCK_USED_READ it becomes a bad indicator for accounting nr_unused_locks; simplyfy by using any first bit.

2020-10-30locking/lockdep: Remove more raw_cpu_read() usagePeter Zijlstra
I initially thought raw_cpu_read() was OK, since if it is !0 we have IRQs disabled and can't get migrated, so if we get migrated both CPUs must have 0 and it doesn't matter which 0 we read. And while that is true; it isn't the whole store, on pretty much all architectures (except x86) this can result in computing the address for one CPU, getting migrated, the old CPU continuing execution with another task (possibly setting recursion) and then the new CPU reading the value of the old CPU, which is no longer 0.

2020-10-30KVM: arm64: Handle Asymmetric AArch32 systemsQais Yousef
On a system without uniform support for AArch32 at EL0, it is possible for the guest to force run AArch32 at EL0 and potentially cause an illegal exception if running on a core without AArch32. Add an extra check so that if we catch the guest doing that, then we prevent it from running again by resetting vcpu->arch.target and return ARM_EXCEPTION_IL. We try to catch this misbehaviour as early as possible and not rely on an illegal exception occuring to signal the problem. Attempting to run a 32bit app in the guest will produce an error from QEMU if the guest exits while running in AArch32 EL0. Tested on Juno by instrumenting the host to fake asym aarch32 and instrumenting KVM to make the asymmetry visible to the guest.

2020-10-30blk-mq: mark flush request as IDLE in flush_end_io()Ming Lei
Mark flush request as IDLE in its .end_io(), aligning it with how normal requests behave. The flush request stays in in-flight tags if we're not using an IO scheduler, so we need to change its state into IDLE. Otherwise, we will hang in blk_mq_tagset_wait_completed_request() during error recovery because flush the request state is kept as COMPLETED.

ibx_irq_pre_postinstall() looks totally pointless. We can just init both SDEIMR and SDEIER at the same time before enabling the master interrupt. It's equally racy as the other order due to doing all of this from the postinstall stage with the interrupt handler already in place. That is, safe with MSI but racy with shared legacy interrupts.

Unfortunately, the ABI is dependent on the specific device features. As such, ambient_light_level range is somewhat different among the supported devices. The ambient_light_zone is even worse: the meanings of each preset are different, and there's no ABI to retrieve the supported types nor their meanins.

2020-10-30docs: ABI: change read/write attributesMauro Carvalho Chehab
Unfortunately, (R) and (W) are valid markups for enumerated lists, as described at: https://docutils.sourceforge.io/docs/ref/rst/restructuredtext.html#enumerated-lists So, we ned to replace them by: (R) -> (Read) (W) -> (Write) As otherwise, (R) will be displayed as R., with is not what it is desired. There's no need to touch (RO) and (RW).

2020-10-30docs: Kconfig/Makefile: add a check for broken ABI filesMauro Carvalho Chehab
The files under Documentation/ABI should follow the syntax as defined at Documentation/ABI/README. Allow checking if they're following the syntax by running the ABI parser script on COMPILE_TEST. With that, when there's a problem with a file under Documentation/ABI, it would produce a warning like: Warning: file ./Documentation/ABI/testing/sysfs-bus-pci-devices-aer_stats#14: What '/sys/bus/pci/devices/<dev>/aer_stats/aer_rootport_total_err_cor' doesn't have a description Warning: file ./Documentation/ABI/testing/sysfs-bus-pci-devices-aer_stats#21: What '/sys/bus/pci/devices/<dev>/aer_stats/aer_rootport_total_err_fatal' doesn't have a description Acked-by: Jonathan Corbet <corbet@lwn.net> Signed-off-by: Mauro Carvalho Chehab <mchehab+huawei@kernel.org> Link: https://lore.kernel.org/r/57a38de85cb4b548857207cf1fc1bf1ee08613c9.1604042072.git.mchehab+huawei@kernel.org Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
