2020-04-24dt-bindings: Fix erroneous 'additionalProperties'Rob Herring
There's several cases of json-schema 'additionalProperties' at the wrong indentation level which has the effect of making them DT properties. This is harmless, but let's fix them so a meta-schema check for this can be added. In all the cases, either the 'additionalProperties' was extra or doesn't work because there's a $ref to more properties. In the latter case, we can use 'unevaluatedProperties' instead.

2020-04-24dt-bindings: Fix command line length limit calling dt-mk-schemaRob Herring
As the number of schemas has increased, we're starting to hit the error "execvp: /bin/sh: Argument list too long". This is due to passing all the schema files on the command line to dt-mk-schema. It currently is only with out of tree builds and is intermittent depending on the file path lengths. Commit 2ba06cd8565b ("kbuild: Always validate DT binding examples") made hitting this proplem more likely since the example validation now always gets the full list of schemas. Fix this by passing the schema file list in a pipe and using xargs. We end up doing the find twice, but the time is insignificant compared to the dt-mk-schema time.

2020-04-22dt-bindings: Re-enable core schemas for dtbs_checkRob Herring
In commit 2ba06cd8565b ("kbuild: Always validate DT binding examples"), the core schemas (from dtschema repo) were inadvertently disabled for dtbs_checks. Re-enable them.

2020-04-17kbuild: check libyaml installation for 'make dt_binding_check'Masahiro Yamada
If you run 'make dtbs_check' without installing the libyaml package, the error message "dtc needs libyaml ..." is shown. This should be checked also for 'make dt_binding_check' because dtc needs to validate *.example.dts extracted from *.yaml files. It is missing since commit 4f0e3a57d6eb ("kbuild: Add support for DT binding schema checks"), but this fix-up is applicable only after commit e10c4321dc1e ("kbuild: allow to run dt_binding_check and dtbs_check in a single command"). I gave the Fixes tag to the latter in case somebody is interested in back-porting this.

2020-04-17of: unittest: kmemleak in duplicate property updateFrank Rowand
kmemleak reports several memory leaks from devicetree unittest. This is the fix for problem 5 of 5. When overlay 'overlay_bad_add_dup_prop' is applied, the apply code properly detects that a memory leak will occur if the overlay is removed since the duplicate property is located in a base devicetree node and reports via printk(): OF: overlay: WARNING: memory leak will occur if overlay removed, property: /testcase-data-2/substation@100/motor-1/rpm_avail OF: overlay: WARNING: memory leak will occur if overlay removed, property: /testcase-data-2/substation@100/motor-1/rpm_avail The overlay is removed when the apply code detects multiple changesets modifying the same property. This is reported via printk(): OF: overlay: ERROR: multiple fragments add, update, and/or delete property /testcase-data-2/substation@100/motor-1/rpm_avail As a result of this error, the overlay is removed resulting in the expected memory leak. Add another device node level to the overlay so that the duplicate property is located in a node added by the overlay, thus no memory leak will occur when the overlay is removed. Thus users of kmemleak will not have to debug this leak in the future.

This sorts the actual field names too, potentially causing even more chaos and confusion at merge time if you have edited the MAINTAINERS file.

2020-04-12MAINTAINERS: sort entries by entry nameLinus Torvalds
They are all supposed to be sorted, but people who add new entries don't always know the alphabet. Plus sometimes the entry names get edited, and people don't then re-order the entry. Let's see how painful this will be for merging purposes (the MAINTAINERS file is often edited in various different trees), but Joe claims there's relatively few patches in -next that touch this, and doing it just before -rc1 is likely the best time. Fingers crossed. This was scripted with /scripts/parse-maintainers.pl --input=MAINTAINERS --output=MAINTAINERS but then I also ended up manually upper-casing a few entry names that stood out when looking at the end result.

2020-04-11KVM: VMX: Extend VMXs #AC interceptor to handle split lock #AC in guestXiaoyao Li
Two types of #AC can be generated in Intel CPUs: 1. legacy alignment check #AC 2. split lock #AC Reflect #AC back into the guest if the guest has legacy alignment checks enabled or if split lock detection is disabled. If the #AC is not a legacy one and split lock detection is enabled, then invoke handle_guest_split_lock() which will either warn and disable split lock detection for this task or force SIGBUS on it. [ tglx: Switch it to handle_guest_split_lock() and rename the misnamed helper function. ] Suggested-by: Sean Christopherson <sean.j.christopherson@intel.com> Signed-off-by: Xiaoyao Li <xiaoyao.li@intel.com> Signed-off-by: Sean Christopherson <sean.j.christopherson@intel.com> Signed-off-by: Thomas Gleixner <tglx@linutronix.de> Signed-off-by: Borislav Petkov <bp@suse.de> Acked-by: Paolo Bonzini <pbonzini@redhat.com> Link: https://lkml.kernel.org/r/20200410115517.176308876@linutronix.de
2020-04-11KVM: x86: Emulate split-lock access as a write in emulatorXiaoyao Li
Emulate split-lock accesses as writes if split lock detection is on to avoid #AC during emulation, which will result in a panic(). This should never occur for a well-behaved guest, but a malicious guest can manipulate the TLB to trigger emulation of a locked instruction[1]. More discussion can be found at [2][3].

2020-04-11x86/split_lock: Provide handle_guest_split_lock()Thomas Gleixner
Without at least minimal handling for split lock detection induced #AC, VMX will just run into the same problem as the VMWare hypervisor, which was reported by Kenneth. It will inject the #AC blindly into the guest whether the guest is prepared or not. Provide a function for guest mode which acts depending on the host SLD mode. If mode == sld_warn, treat it like user space, i.e. emit a warning, disable SLD and mark the task accordingly. Otherwise force SIGBUS.
