2019-09-24KVM: selftests: Create VM earlier for dirty log testPeter Xu1-3/+16
Since we've just removed the dependency of vm type in previous patch, now we can create the vm much earlier. Note that to move it earlier we used an approximation of number of extra pages but it should be fine. This prepares for the follow up patches to finally remove the duplication of guest mode parsings.

2019-09-24KVM: selftests: Move vm type into _vm_create() internallyPeter Xu3-20/+17
Rather than passing the vm type from the top level to the end of vm creation, let's simply keep that as an internal of kvm_vm struct and decide the type in _vm_create(). Several reasons for doing this: - The vm type is only decided by physical address width and currently only used in aarch64, so we've got enough information as long as we're passing vm_guest_mode into _vm_create(), - This removes a loop dependency between the vm->type and creation of vms. That's why now we need to parse vm_guest_mode twice sometimes, once in run_test() and then again in _vm_create(). The follow up patches will move on to clean up that as well so we can have a single place to decide guest machine types and so. Note that this patch will slightly change the behavior of aarch64 tests in that previously most vm_create() callers will directly pass in type==0 into _vm_create() but now the type will depend on vm_guest_mode, however it shouldn't affect any user because all vm_create() users of aarch64 will be using VM_MODE_DEFAULT guest mode (which is VM_MODE_P40V48_4K) so at last type will still be zero.

2019-09-24KVM: x86: announce KVM_CAP_HYPERV_ENLIGHTENED_VMCS support only when it is availableVitaly Kuznetsov1-2/+4
It was discovered that after commit 65efa61dc0d5 ("selftests: kvm: provide common function to enable eVMCS") hyperv_cpuid selftest is failing on AMD. The reason is that the commit changed _vcpu_ioctl() to vcpu_ioctl() in the test and this one can't fail. Instead of fixing the test is seems to make more sense to not announce KVM_CAP_HYPERV_ENLIGHTENED_VMCS support if it is definitely missing (on svm and in case kvm_intel.nested=0).

Since commit 5158917c7b019 ("KVM: x86: nVMX: Allow nested_enable_evmcs to be NULL") the code in x86.c is prepared to see nested_enable_evmcs being NULL and in VMX case it actually is when nesting is disabled.

Hyper-V direct tlb flush function should be enabled for guest that only uses Hyper-V hypercall. User space hypervisor(e.g, Qemu) can disable KVM identification in CPUID and just exposes Hyper-V identification to make sure the precondition.

Pull SafeSetID fix from Micah Morton: "Jann Horn sent some patches to fix some bugs in SafeSetID for 5.3. After he had done his testing there were a couple small code tweaks that went in and caused this bug. From what I can see SafeSetID is broken in 5.3 and crashes the kernel every time during initialization if you try to use it. I came across this bug when backporting Jann's changes for 5.3 to older kernels (4.14 and 4.19). I've tested on a Chrome OS device with those kernels and verified that this change fixes things. It doesn't seem super useful to have this bake in linux-next, since it is completely broken in 5.3 and nobody noticed" * tag 'safesetid-bugfix-5.4' of git://github.com/micah-morton/linux: LSM: SafeSetID: Stop releasing uninitialized ruleset

Previously we would return an error if we couldn't allocate a new cache entry, now we always return the label even if we can't create a new cache entry for it. - Convert the sidtab atomic_t counter to a normal u32 with READ/WRITE_ONCE() and memory barrier protection. - A few patches to policydb.c to clean things up (remove forward declarations, long lines, bad variable names, etc) * tag 'selinux-pr-20190917' of git://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/selinux: lsm: remove current_security() selinux: fix residual uses of current_security() for the SELinux blob selinux: avoid atomic_t usage in sidtab fanotify, inotify, dnotify, security: add security hook for fs notifications selinux: always return a secid from the network caches if we find one selinux: policydb - rename type_val_to_struct_array selinux: policydb - fix some checkpatch.pl warnings selinux: shuffle around policydb.c to get rid of forward declarations

2019-09-22firmware: bcm47xx_nvram: _really_ correct size_t printf formatLinus Torvalds1-1/+1
Commit feb4eb060c3a ("firmware: bcm47xx_nvram: Correct size_t printf format") was wrong, and changed a printout of 'header.len' - which is an u32 type - to use '%zu'. It apparently did pattern matching on the other case, where it printed out 'nvram_len', which is indeed of type 'size_t'. Rather than undoing the change, this just makes it use the variable that the change seemed to expect to be used.

2019-09-22modules: make MODULE_IMPORT_NS() work even when modular builds are disabledLinus Torvalds1-2/+2
It's an unusual configuration, and was apparently never tested, and not caught in linux-next because of a combination of travels and it making it into the tree too late. The fix is to simply move the #define to outside the CONFIG_MODULE section, since MODULE_INFO() will do the right thing.
