commit f2ae85b2 upstream. Since KVM internally represents the ICFGR registers by stuffing two of them into one word, the offset for accessing the internal representation and the one for the MMIO based access are different. So keep the original offset around, but adjust the internal array offset by one bit. Reported-by:

commit 6cbde825 upstream. Add a stub for kvm_vgic_addr when compiling without CONFIG_KVM_ARM_VGIC. The usefulness of this configurarion is extremely doubtful, but let's fix it anyway (until we decide that we'll always support a VGIC). Reported-by:

commit 8034699a upstream. In order to be able to detect the point where the guest enables its MMU and caches, trap all the VM related system registers. Once we see the guest enabling both the MMU and the caches, we can go back to a saner mode of operation, which is to leave these registers in complete control of the guest. Signed-off-by:

commit af20814e upstream. HCR.TVM traps (among other things) accesses to AMAIR0 and AMAIR1. In order to minimise the amount of surprise a guest could generate by trying to access these registers with caches off, add them to the list of registers we switch/handle. Signed-off-by:

commit ac30a11e upstream. So far, KVM/ARM used a fixed HCR configuration per guest, except for the VI/VF/VA bits to control the interrupt in absence of VGIC. With the upcoming need to dynamically reconfigure trapping, it becomes necessary to allow the HCR to be changed on a per-vcpu basis. The fix here is to mimic what KVM/arm64 already does: a per vcpu HCR field, initialized at setup time. Signed-off-by:

commit 547f7813 upstream. Commit 240e99cb (ARM: KVM: Fix 64-bit coprocessor handling) added an ordering dependency for the 64bit registers. The order described is: CRn, CRm, Op1, Op2, 64bit-first. Unfortunately, the implementation is: CRn, 64bit-first, CRm... Move the 64bit test to be last in order to match the documentation. Signed-off-by:

commit 46c214dd upstream. Commit 240e99cb (ARM: KVM: Fix 64-bit coprocessor handling) changed the way we match the 64bit coprocessor access from user space, but didn't update the trap handler for the same set of registers. The effect is that a trapped 64bit access is never matched, leading to a fault being injected into the guest. This went unnoticed as we didn't really trap any 64bit register so far. Placing the CRm field of the access into the CRn field of the matching structure fixes the problem. Also update the debug feature to emit the expected string in case of failing match. Signed-off-by:

commit 15979300 upstream. In order for a guest with caches disabled to observe data written contained in a given page, we need to make sure that page is committed to memory, and not just hanging in the cache (as guest accesses are completely bypassing the cache until it decides to enable it). For this purpose, hook into the coherent_cache_guest_page function and flush the region if the guest SCTLR register doesn't show the MMU and caches as being enabled. Signed-off-by:

commit 9d218a1f upstream. When the guest runs with caches disabled (like in an early boot sequence, for example), all the writes are diectly going to RAM, bypassing the caches altogether. Once the MMU and caches are enabled, whatever sits in the cache becomes suddenly visible, which isn't what the guest expects. A way to avoid this potential disaster is to invalidate the cache when the MMU is being turned on. For this, we hook into the SCTLR_EL1 trapping code, and scan the stage-2 page tables, invalidating the pages/sections that have already been mapped in. Signed-off-by:

commit a3c8bd31 upstream. The use of p*d_addr_end with stage-2 translation is slightly dodgy, as the IPA is 40bits, while all the p*d_addr_end helpers are taking an unsigned long (arm64 is fine with that as unligned long is 64bit). The fix is to introduce 64bit clean versions of the same helpers, and use them in the stage-2 page table code. Signed-off-by:

commit 2072d29c upstream. The current handling of AArch32 trapping is slightly less than perfect, as it is not possible (from a handler point of view) to distinguish it from an AArch64 access, nor to tell a 32bit from a 64bit access either. Fix this by introducing two additional flags: - is_aarch32: true if the access was made in AArch32 mode - is_32bit: true if is_aarch32 == true and a MCR/MRC instruction was used to perform the access (as opposed to MCRR/MRRC). This allows a handler to cover all the possible conditions in which a system register gets trapped. Signed-off-by:

commit b20c9f29 upstream. Commit 1fcf7ce0 (arm: kvm: implement CPU PM notifier) added support for CPU power-management, using a cpu_notifier to re-init KVM on a CPU that entered CPU idle. The code assumed that a CPU entering idle would actually be powered off, loosing its state entierely, and would then need to be reinitialized. It turns out that this is not always the case, and some HW performs CPU PM without actually killing the core. In this case, we try to reinitialize KVM while it is still live. It ends up badly, as reported by Andre Przywara (using a Calxeda Midway): [ 3.663897] Kernel panic - not syncing: unexpected prefetch abort in Hyp mode at: 0x685760 [ 3.663897] unexpected data abort in Hyp mode at: 0xc067d150 [ 3.663897] unexpected HVC/SVC trap in Hyp mode at: 0xc0901dd0 The trick here is to detect if we've been through a full re-init or not by looking at HVBAR (VBAR_EL2 on arm64). This involves implementing the backend for __hyp_get_vectors in the main KVM HYP code (rather small), and checking the return value against the default one when the CPU notifier is called on CPU_PM_EXIT.

commit 478a8237 upstream. The current KVM implementation of PSCI returns INVALID_PARAMETERS if the waitqueue for the corresponding CPU is not active. This does not seem correct, since KVM should not care what the specific thread is doing, for example, user space may not have called KVM_RUN on this VCPU yet or the thread may be busy looping to user space because it received a signal; this is really up to the user space implementation. Instead we should check specifically that the CPU is marked as being turned off, regardless of the VCPU thread state, and if it is, we shall simply clear the pause flag on the CPU and wake up the thread if it happens to be blocked for us. Further, the implementation seems to be racy when executing multiple VCPU threads. There really isn't a reasonable user space programming scheme to ensure all secondary CPUs have reached kvm_vcpu_first_run_init before turning on the boot CPU. Therefore, set the pause flag on the vcpu at VCPU init time (which can reasonably be expected to be completed for all CPUs by user space before running any VCPUs) and clear both this flag and the feature (in case the feature can somehow get set again in the future) and ping the waitqueue on turning on a VCPU using PSCI.

commit e9b152cb upstream. The arch-generic KVM code expects the cpu field of a vcpu to be -1 if the vcpu is no longer assigned to a cpu. This is used for the optimized make_all_cpus_request path and will be used by the vgic code to check that no vcpus are running. Acked-by:

commit e1ba0207 upstream. Rework the VGIC initialization slightly to allow initialization of the vgic cpu-specific state even if the irqchip (the VGIC) hasn't been created by user space yet. This is safe, because the vgic data structures are already allocated when the CPU is allocated if VGIC support is compiled into the kernel. Further, the init process does not depend on any other information and the sacrifice is a slight performance degradation for creating VMs in the no-VGIC case. The reason is that the new device control API doesn't mandate creating the VGIC before creating the VCPU and it is unreasonable to require user space to create the VGIC before creating the VCPUs. At the same time move the irqchip_in_kernel check out of kvm_vcpu_first_run_init and into the init function to make the per-vcpu and global init functions symmetric and add comments on the exported functions making it a bit easier to understand the init flow by only looking at vgic.c.

commit d241aac7 upstream. On an (even slightly) oversubscribed system, spinlocks are quickly becoming a bottleneck, as some vcpus are spinning, waiting for a lock to be released, while the vcpu holding the lock may not be running at all. The solution is to trap blocking WFEs and tell KVM that we're now spinning. This ensures that other vpus will get a scheduling boost, allowing the lock to be released more quickly. Also, using CONFIG_HAVE_KVM_CPU_RELAX_INTERCEPT slightly improves the performance when the VM is severely overcommited. Acked-by:

commit 79c64880 upstream. The KVM PSCI code blindly assumes that vcpu_id and MPIDR are the same thing. This is true when vcpus are organized as a flat topology, but is wrong when trying to emulate any other topology (such as A15 clusters). Change the KVM PSCI CPU_ON code to look at the MPIDR instead of the vcpu_id to pick a target CPU. Signed-off-by:

commit 1f558098 upstream. On an (even slightly) oversubscribed system, spinlocks are quickly becoming a bottleneck, as some vcpus are spinning, waiting for a lock to be released, while the vcpu holding the lock may not be running at all. This creates contention, and the observed slowdown is 40x for hackbench. No, this isn't a typo. The solution is to trap blocking WFEs and tell KVM that we're now spinning. This ensures that other vpus will get a scheduling boost, allowing the lock to be released more quickly. Also, using CONFIG_HAVE_KVM_CPU_RELAX_INTERCEPT slightly improves the performance when the VM is severely overcommited. Quick test to estimate the performance: hackbench 1 process 1000 2xA15 host (baseline): 1.843s 2xA15 guest w/o patch: 2.083s 4xA15 guest w/o patch: 80.212s 8xA15 guest w/o patch: Could not be bothered to find out 2xA15 guest w/ patch: 2.102s 4xA15 guest w/ patch: 3.205s 8xA15 guest w/ patch: 6.887s So we go from a 40x degradation to 1.5x in the 2x overcommit case, which is vaguely more acceptable.

commit 5e497046 upstream. The T{0,1}SZ fields of TTBCR are 3 bits wide when using the long descriptor format. Likewise, the T0SZ field of the HTCR is 3-bits. KVM currently defines TTBCR_T{0,1}SZ as 3, not 7. The T0SZ mask is used to calculate the value for the HTCR, both to pick out TTBCR.T0SZ and mask off the equivalent field in the HTCR during read-modify-write. The incorrect mask size causes the (UNKNOWN) reset value of HTCR.T0SZ to leak in to the calculated HTCR value. Linux will hang when initializing KVM if HTCR's reset value has bit 2 set (sometimes the case on A7/TC2) Fixing T0SZ allows A7 cores to boot and T1SZ is also fixed for completeness. Signed-off-by:

commit 1158fca4 upstream. KVM does not have a notion of multiple clusters for CPUs, just a linear array of CPUs. When using a system with cores in more than one cluster, the current method for calculating the virtual MPIDR will leak the (physical) cluster information into the virtual MPIDR. One effect of this is that Linux under KVM fails to boot multiple CPUs that aren't in the 0th cluster. This patch does away with exposing the real MPIDR fields in favour of simply using the virtual CPU number (but preserving the U bit, as before). Signed-off-by:

commit db29a950 upstream. Given following iptables ruleset: -P FORWARD DROP -A FORWARD -m sctp --dport 9 -j ACCEPT -A FORWARD -p tcp --dport 80 -j ACCEPT -A FORWARD -p tcp -m conntrack -m state ESTABLISHED,RELATED -j ACCEPT One would assume that this allows SCTP on port 9 and TCP on port 80. Unfortunately, if the SCTP conntrack module is not loaded, this allows *all* SCTP communication, to pass though, i.e. -p sctp -j ACCEPT, which we think is a security issue. This is because on the first SCTP packet on port 9, we create a dummy "generic l4" conntrack entry without any port information (since conntrack doesn't know how to extract this information). All subsequent packets that are unknown will then be in established state since they will fallback to proto_generic and will match the 'generic' entry. Our originally proposed version [1] completely disabled generic protocol tracking, but Jozsef suggests to not track protocols for which a more suitable helper is available, hence we now mitigate the issue for in tree known ct protocol helpers only, so that at least NAT and direction information will still be preserved for others.
