I'll queue the series shortly so that it can simmer in -next for a bit. Potential fixes can go on top if required. M.

This is the fourth version of this series introducing ERET and PAuth support for NV guests, and now the base prefix for the NV support series. Unless someone shouts, I intend to take this in for 6.10. * From v3 [3] - Check for NV support before checking for HCR_EL2.NV on vpcu exit - Rebased on 6.9-rc1 * From v2 [2] - Enforce that both Address and Generic authentication use the same algorithm - Reduce PAuth trapping by eagerly setting the HCR_EL2.API/APK bits - Collected RBs, with thanks - Rebased on kvmarm-6.9 * From v1 [1]: - Don't repaint the ISS_ERET* definitions, but provide reasonable helpers instead - Dropped superfluous VNCR_EL2 definition - Amended comments and creative spelling [1] https://lore.kernel.org/r/20240219092014.783809-1-maz@kernel.org [2] https://lore.kernel.org/r/20240226100601.2379693-1-maz@kernel.org [3] https://lore.kernel.org/r/20240321155356.3236459-1-maz@kernel.org Marc Zyngier (15): KVM: arm64: Harden __ctxt_sys_reg() against out-of-range values KVM: arm64: Add helpers for ESR_ELx_ERET_ISS_ERET* KVM: arm64: Constraint PAuth support to consistent implementations KVM: arm64: nv: Drop VCPU_HYP_CONTEXT flag KVM: arm64: nv: Configure HCR_EL2 for FEAT_NV2 KVM: arm64: nv: Add trap forwarding for ERET and SMC KVM: arm64: nv: Fast-track 'InHost' exception returns KVM: arm64: nv: Honor HFGITR_EL2.ERET being set KVM: arm64: nv: Handle HCR_EL2.{API,APK} independently KVM: arm64: nv: Reinject PAC exceptions caused by HCR_EL2.API==0 KVM: arm64: nv: Add kvm_has_pauth() helper KVM: arm64: nv: Add emulation for ERETAx instructions KVM: arm64: nv: Handle ERETA[AB] instructions KVM: arm64: nv: Advertise support for PAuth KVM: arm64: Drop trapping of PAuth instructions/keys arch/arm64/include/asm/esr.h | 12 ++ arch/arm64/include/asm/kvm_emulate.h | 10 -- arch/arm64/include/asm/kvm_host.h | 26 +++- arch/arm64/include/asm/kvm_nested.h | 13 ++ arch/arm64/include/asm/kvm_ptrauth.h | 21 +++ arch/arm64/include/asm/pgtable-hwdef.h | 1 + arch/arm64/kvm/Makefile | 1 + arch/arm64/kvm/arm.c | 83 +++++++++- arch/arm64/kvm/emulate-nested.c | 66 +++++--- arch/arm64/kvm/handle_exit.c | 36 ++++- arch/arm64/kvm/hyp/include/hyp/switch.h | 62 +------- arch/arm64/kvm/hyp/nvhe/switch.c | 4 +- arch/arm64/kvm/hyp/vhe/switch.c | 96 +++++++++++- arch/arm64/kvm/nested.c | 8 +- arch/arm64/kvm/pauth.c | 196 ++++++++++++++++++++++++ 15 files changed, 514 insertions(+), 121 deletions(-) create mode 100644 arch/arm64/kvm/pauth.c
