2023-08-03spi: mpc5xxx-psc: Fix unsigned expression compared with zeroLi Zetao
There is two warnings reported by coccinelle: ./drivers/spi/spi-mpc512x-psc.c:493:5-13: WARNING: Unsigned expression compared with zero: mps -> irq < 0 ./drivers/spi/spi-mpc52xx-psc.c:332:5-13: WARNING: Unsigned expression compared with zero: mps -> irq < 0 The commit "208ee586f862" ("spi: mpc5xxx-psc: Return immediately if IRQ resource is unavailable") was to check whether the IRQ resource is unavailable. When the IRQ resource is unavailable, an error code is returned, however, the type of "mps->irq" is "unsigned int", causing the error code to flip. Modify the type of "mps->irq" to solve this problem.

Instead, create a separate variable to use to notify readers to reset. - Fix the ref counts of the "soft disable" mode.

2023-07-29arch/*/configs/*defconfig: Replace AUTOFS4_FS by AUTOFS_FSSven Joachim
Commit a2225d931f75 ("autofs: remove left-over autofs4 stubs") promised the removal of the fs/autofs/Kconfig fragment for AUTOFS4_FS within a couple of releases, but five years later this still has not happened yet, and AUTOFS4_FS is still enabled in 63 defconfigs. Get rid of it mechanically: git grep -l CONFIG_AUTOFS4_FS -- '*defconfig' | xargs sed -i 's/AUTOFS4_FS/AUTOFS_FS/' Also just remove the AUTOFS4_FS config option stub. Anybody who hasn't regenerated their config file in the last five years will need to just get the new name right when they do.

2023-07-29KVM: selftests: Expand x86's sregs test to cover illegal CR0 valuesSean Christopherson
Add coverage to x86's set_sregs_test to verify KVM rejects vendor-agnostic illegal CR0 values, i.e. CR0 values whose legality doesn't depend on the current VMX mode. KVM historically has neglected to reject bad CR0s from userspace, i.e. would happily accept a completely bogus CR0 via KVM_SET_SREGS{2}. Punt VMX specific subtests to future work, as they would require quite a bit more effort, and KVM gets coverage for CR0 checks in general through other means, e.g. KVM-Unit-Tests.

2023-07-29KVM: VMX: Don't fudge CR0 and CR4 for restricted L2 guestSean Christopherson
Stuff CR0 and/or CR4 to be compliant with a restricted guest if and only if KVM itself is not configured to utilize unrestricted guests, i.e. don't stuff CR0/CR4 for a restricted L2 that is running as the guest of an unrestricted L1. Any attempt to VM-Enter a restricted guest with invalid CR0/CR4 values should fail, i.e. in a nested scenario, KVM (as L0) should never observe a restricted L2 with incompatible CR0/CR4, since nested VM-Enter from L1 should have failed. And if KVM does observe an active, restricted L2 with incompatible state, e.g. due to a KVM bug, fudging CR0/CR4 instead of letting VM-Enter fail does more harm than good, as KVM will often neglect to undo the side effects, e.g. won't clear rmode.vm86_active on nested VM-Exit, and thus the damage can easily spill over to L1. On the other hand, letting VM-Enter fail due to bad guest state is more likely to contain the damage to L2 as KVM relies on hardware to perform most guest state consistency checks, i.e. KVM needs to be able to reflect a failed nested VM-Enter into L1 irrespective of (un)restricted guest behavior.

2023-07-29KVM: x86: Disallow KVM_SET_SREGS{2} if incoming CR0 is invalidSean Christopherson
Reject KVM_SET_SREGS{2} with -EINVAL if the incoming CR0 is invalid, e.g. due to setting bits 63:32, illegal combinations, or to a value that isn't allowed in VMX (non-)root mode. The VMX checks in particular are "fun" as failure to disallow Real Mode for an L2 that is configured with unrestricted guest disabled, when KVM itself has unrestricted guest enabled, will result in KVM forcing VM86 mode to virtual Real Mode for L2, but then fail to unwind the related metadata when synthesizing a nested VM-Exit back to L1 (which has unrestricted guest enabled). Opportunistically fix a benign typo in the prototype for is_valid_cr4().

2023-07-29Revert "debugfs, coccinelle: check for obsolete DEFINE_SIMPLE_ATTRIBUTE() usage"Sean Christopherson
Remove coccinelle's recommendation to use DEFINE_DEBUGFS_ATTRIBUTE() instead of DEFINE_SIMPLE_ATTRIBUTE(). Regardless of whether or not the "significant overhead" incurred by debugfs_create_file() is actually meaningful, warnings from the script have led to a rash of low-quality patches that have sowed confusion and consumed maintainer time for little to no benefit. There have been no less than four attempts to "fix" KVM, and a quick search on lore shows that KVM is not alone. This reverts commit 5103068eaca290f890a30aae70085fac44cecaf6.
