2024-09-10KVM: arm64: Add memory length checks and remove inline in do_ffa_mem_xferSnehal Koukuntla
When we share memory through FF-A and the description of the buffers exceeds the size of the mapped buffer, the fragmentation API is used. The fragmentation API allows specifying chunks of descriptors in subsequent FF-A fragment calls and no upper limit has been established for this. The entire memory region transferred is identified by a handle which can be used to reclaim the transferred memory. To be able to reclaim the memory, the description of the buffers has to fit in the ffa_desc_buf. Add a bounds check on the FF-A sharing path to prevent the memory reclaim from failing. Also do_ffa_mem_xfer() does not need __always_inline, except for the BUILD_BUG_ON() aspect, which gets moved to a macro. [maz: fixed the BUILD_BUG_ON() breakage with LLVM, thanks to Wei-Lin Chang for the timely report] Fixes: 634d90cf0ac65 ("KVM: arm64: Handle FFA_MEM_LEND calls from the host") Cc: stable@vger.kernel.org Reviewed-by: Sebastian Ene <sebastianene@google.com> Signed-off-by: Snehal Koukuntla <snehalreddy@google.com> Reviewed-by: Oliver Upton <oliver.upton@linux.dev> Link: https://lore.kernel.org/r/20240909180154.3267939-1-snehalreddy@google.com Signed-off-by: Marc Zyngier <maz@kernel.org>
2024-08-29KVM: arm64: selftests: Cope with lack of GICv3 in set_id_regsOliver Upton
Broonie reports that the set_id_regs test is failing as of commit 5cb57a1aff75 ("KVM: arm64: Zero ID_AA64PFR0_EL1.GIC when no GICv3 is presented to the guest"). The test does not anticipate the 'late' ID register fixup where KVM clobbers the GIC field in absence of GICv3. While the field technically has FTR_LOWER_SAFE behavior, fix the issue by setting it to an exact value of 0, matching the effect of the 'late' fixup.

2024-08-27KVM: arm64: Unify UNDEF injection helpersMarc Zyngier
We currently have two helpers (undef_access() and trap_undef()) that do exactly the same thing: inject an UNDEF and return 'false' (as an indication that PC should not be incremented). We definitely could do with one less. Given that undef_access() is used 80ish times, while trap_undef() is only used 30 times, the latter loses the battle and is immediately sacrificed. We also have a large number of instances where undef_access() is open-coded. Let's also convert those.

2024-08-27KVM: arm64: Make most GICv3 accesses UNDEF if they trapMarc Zyngier
We don't expect to trap any GICv3 register for host handling, apart from ICC_SRE_EL1 and the SGI registers. If they trap, that's because the guest is playing with us despite being told it doesn't have a GICv3. If it does, UNDEF is what it will get.

2024-08-27KVM: arm64: Zero ID_AA64PFR0_EL1.GIC when no GICv3 is presented to the guestMarc Zyngier
In order to be consistent, we shouldn't advertise a GICv3 when none is actually usable by the guest. Wipe the feature when these conditions apply, and allow the field to be written from userspace. This now allows us to rewrite the kvm_has_gicv3 helper() in terms of kvm_has_feat(), given that it is always evaluated at runtime.

2024-08-27KVM: arm64: Force GICv3 trap activation when no irqchip is configured on VHEMarc Zyngier
On a VHE system, no GICv3 traps get configured when no irqchip is present. This is not quite matching the "no GICv3" semantics that we want to present. Force such traps to be configured in this case.

2024-08-27KVM: arm64: Force SRE traps when SRE access is not enabledMarc Zyngier
We so far only write the ICH_HCR_EL2 config in two situations: - when we need to emulate the GICv3 CPU interface due to HW bugs - when we do direct injection, as the virtual CPU interface needs to be enabled This is all good. But it also means that we don't do anything special when we emulate a GICv2, or that there is no GIC at all. What happens in this case when the guest uses the GICv3 system registers? The *guest* gets a trap for a sysreg access (EC=0x18) while we'd really like it to get an UNDEF. Fixing this is a bit involved: - we need to set all the required trap bits (TC, TALL0, TALL1, TDIR) - for these traps to take effect, we need to (counter-intuitively) set ICC_SRE_EL1.SRE to 1 so that the above traps take priority. Note that doesn't fully work when GICv2 emulation is enabled, as we cannot set ICC_SRE_EL1.SRE to 1 (it breaks Group0 delivery as IRQ).
