2024-10-31KVM: arm64: nv: Honor MDCR_EL2.{TPM, TPMCR} in Host EL0Oliver Upton
TPM and TPMCR trap bits also affect Host EL0. How fun. Mark these two trap bits as such and take advantage of the new infrastructure for dealing w/ EL0 traps.

2024-10-31KVM: arm64: nv: Reinject traps that take effect in Host EL0Oliver Upton
Wire up the other end of traps that affect host EL0 by actually injecting them into the guest hypervisor. Skip over FGT entirely, as a cursory glance suggests no FGT is effective in host EL0. Note that kvm_inject_nested() is already equipped for handling exceptions while the VM is already in a host context.

2024-10-31KVM: arm64: nv: Allow coarse-grained trap combos to use complex trapsOliver Upton
KVM uses a sanity-check to avoid infinite recursion in trap combinations that could potentially depend on itself. Narrow the scope of this sanity check to the exact CGT IDs that correspond w/ trap combos, opening the door to using 'complex' traps as part of a combination.

2024-10-31KVM: arm64: Extend masking facility to arbitrary registersMarc Zyngier
We currently only use the masking (RES0/RES1) facility for VNCR registers, as they are memory-based and thus easy to sanitise. But we could apply the same thing to other registers if we: - split the sanitisation from __VNCR_START__ - apply the sanitisation when reading from a HW register This involves a new "marker" in the vcpu_sysreg enum, which defines the point at which the sanitisation applies (the VNCR registers being of course after this marker). Whle we are at it, rename kvm_vcpu_sanitise_vncr_reg() to kvm_vcpu_apply_reg_masks(), which is vaguely more explicit, and harden set_sysreg_masks() against setting masks for random registers...

2024-10-31KVM: arm64: Correctly access TCR2_EL1, PIR_EL1, PIRE0_EL1 with VHEMarc Zyngier
For code that accesses any of the guest registers for emulation purposes, it is crucial to know where the most up-to-date data is. While this is pretty clear for nVHE (memory is the sole repository), things are a lot muddier for VHE, as depending on the SYSREGS_ON_CPU flag, registers can either be loaded on the HW or be in memory. Even worse with NV, where the loaded state is by definition partial. For these reasons, KVM offers the vcpu_read_sys_reg() and vcpu_write_sys_reg() primitives that always do the right thing. However, these primitive must know what register to access, and this is the role of the __vcpu_read_sys_reg_from_cpu() and __vcpu_write_sys_reg_to_cpu() helpers. As it turns out, TCR2_EL1, PIR_EL1, PIRE0_EL1 and not described in the latter helpers, meaning that the AT code cannot use them to emulate S1PIE. Add the three registers to the (long) list.

2024-10-31KVM: arm64: nv: Save/Restore vEL2 sysregsMarc Zyngier
Whenever we need to restore the guest's system registers to the CPU, we now need to take care of the EL2 system registers as well. Most of them are accessed via traps only, but some have an immediate effect and also a guest running in VHE mode would expect them to be accessible via their EL1 encoding, which we do not trap. For vEL2 we write the virtual EL2 registers with an identical format directly into their EL1 counterpart, and translate the few registers that have a different format for the same effect on the execution when running a non-VHE guest guest hypervisor. Based on an initial patch from Andre Przywara, rewritten many times since.

2024-10-31KVM: arm64: nv: Handle CNTHCTL_EL2 speciallyMarc Zyngier
Accessing CNTHCTL_EL2 is fraught with danger if running with HCR_EL2.E2H=1: half of the bits are held in CNTKCTL_EL1, and thus can be changed behind our back, while the rest lives in the CNTHCTL_EL2 shadow copy that is memory-based. Yes, this is a lot of fun! Make sure that we merge the two on read access, while we can write to CNTKCTL_EL1 in a more straightforward manner.

2024-10-27firewire: core: fix invalid port index for parent deviceTakashi Sakamoto
In a commit 24b7f8e5cd65 ("firewire: core: use helper functions for self ID sequence"), the enumeration over self ID sequence was refactored with some helper functions with KUnit tests. These helper functions are guaranteed to work expectedly by the KUnit tests, however their application includes a mistake to assign invalid value to the index of port connected to parent device. This bug affects the case that any extra node devices which has three or more ports are connected to 1394 OHCI controller. In the case, the path to update the tree cache could hits WARN_ON(), and gets general protection fault due to the access to invalid address computed by the invalid value. This commit fixes the bug to assign correct port index.

2024-10-25x86: fix whitespace in runtime-const assembler outputLinus Torvalds

2024-10-25x86: fix user address masking non-canonical speculation issueLinus Torvalds
It turns out that AMD has a "Meltdown Lite(tm)" issue with non-canonical accesses in kernel space. And so using just the high bit to decide whether an access is in user space or kernel space ends up with the good old "leak speculative data" if you have the right gadget using the result: CVE-2020-12965 “Transient Execution of Non-Canonical Accesses“ Now, the kernel surrounds the access with a STAC/CLAC pair, and those instructions end up serializing execution on older Zen architectures, which closes the speculation window. But that was true only up until Zen 5, which renames the AC bit [1]. That improves performance of STAC/CLAC a lot, but also means that the speculation window is now open. Note that this affects not just the new address masking, but also the regular valid_user_address() check used by access_ok(), and the asm version of the sign bit check in the get_user() helpers. It does not affect put_user() or clear_user() variants, since there's no speculative result to be used in a gadget for those operations.
