2019-06-28x86/vsyscall: Add a new vsyscall=xonly modeAndy Lutomirski
With vsyscall emulation on, a readable vsyscall page is still exposed that contains syscall instructions that validly implement the vsyscalls. This is required because certain dynamic binary instrumentation tools attempt to read the call targets of call instructions in the instrumented code. If the instrumented code uses vsyscalls, then the vsyscall page needs to contain readable code. Unfortunately, leaving readable memory at a deterministic address can be used to help various ASLR bypasses, so some hardening value can be gained by disallowing vsyscall reads. Given how rarely the vsyscall page needs to be readable, add a mechanism to make the vsyscall page be execute only.

2019-06-21x86/vdso: Prevent segfaults due to hoisted vclock readsAndy Lutomirski
GCC 5.5.0 sometimes cleverly hoists reads of the pvclock and/or hvclock pages before the vclock mode checks. This creates a path through vclock_gettime() in which no vclock is enabled at all (due to disabled TSC on old CPUs, for example) but the pvclock or hvclock page nevertheless read. This will segfault on bare metal. This fixes commit 459e3a21535a ("gcc-9: properly declare the {pv,hv}clock_page storage") in the sense that, before that commit, GCC didn't seem to generate the offending code. There was nothing wrong with that commit per se, and -stable maintainers should backport this to all supported kernels regardless of whether the offending commit was present, since the same crash could just as easily be triggered by the phase of the moon. On GCC 9.1.1, this doesn't seem to affect the generated code at all, so I'm not too concerned about performance regressions from this fix.

2019-06-20KVM: nVMX: reorganize initial steps of vmx_set_nested_statePaolo Bonzini
Commit 332d079735f5 ("KVM: nVMX: KVM_SET_NESTED_STATE - Tear down old EVMCS state before setting new state", 2019-05-02) broke evmcs_test because the eVMCS setup must be performed even if there is no VMXON region defined, as long as the eVMCS bit is set in the assist page. While the simplest possible fix would be to add a check on kvm_state->flags & KVM_STATE_NESTED_EVMCS in the initial "if" that covers kvm_state->hdr.vmx.vmxon_pa == -1ull, that is quite ugly. Instead, this patch moves checks earlier in the function and conditionalizes them on kvm_state->hdr.vmx.vmxon_pa, so that vmx_set_nested_state always goes through vmx_leave_nested and nested_enable_evmcs.

2019-06-19KVM: x86: Modify struct kvm_nested_state to have explicit fields for dataLiran Alon
Improve the KVM_{GET,SET}_NESTED_STATE structs by detailing the format of VMX nested state data in a struct. In order to avoid changing the ioctl values of KVM_{GET,SET}_NESTED_STATE, there is a need to preserve sizeof(struct kvm_nested_state). This is done by defining the data struct as "data.vmx[0]". It was the most elegant way I found to preserve struct size while still keeping struct readable and easy to maintain. It does have a misfortunate side-effect that now it has to be accessed as "data.vmx[0]" rather than just "data.vmx". Because we are already modifying these structs, I also modified the following: * Define the "format" field values as macros. * Rename vmcs_pa to vmcs12_pa for better readability.

2019-06-14x86/kasan: Fix boot with 5-level paging and KASANAndrey Ryabinin
Since commit d52888aa2753 ("x86/mm: Move LDT remap out of KASLR region on 5-level paging") kernel doesn't boot with KASAN on 5-level paging machines. The bug is actually in early_p4d_offset() and introduced by commit 12a8cc7fcf54 ("x86/kasan: Use the same shadow offset for 4- and 5-level paging") early_p4d_offset() tries to convert pgd_val(*pgd) value to a physical address. This doesn't make sense because pgd_val() already contains the physical address. It did work prior to commit d52888aa2753 because the result of "__pa_nodebug(pgd_val(*pgd)) & PTE_PFN_MASK" was the same as "pgd_val(*pgd) & PTE_PFN_MASK". __pa_nodebug() just set some high bits which were masked out by applying PTE_PFN_MASK. After the change of the PAGE_OFFSET offset in commit d52888aa2753 __pa_nodebug(pgd_val(*pgd)) started to return a value with more high bits set and PTE_PFN_MASK wasn't enough to mask out all of them. So it returns a wrong not even canonical address and crashes on the attempt to dereference it. Switch back to pgd_val() & PTE_PFN_MASK to cure the issue.

2019-06-12x86/resctrl: Don't stop walking closids when a locksetup group is foundJames Morse
When a new control group is created __init_one_rdt_domain() walks all the other closids to calculate the sets of used and unused bits. If it discovers a pseudo_locksetup group, it breaks out of the loop. This means any later closid doesn't get its used bits added to used_b. These bits will then get set in unused_b, and added to the new control group's configuration, even if they were marked as exclusive for a later closid. When encountering a pseudo_locksetup group, we should continue. This is because "a resource group enters 'pseudo-locked' mode after the schemata is written while the resource group is in 'pseudo-locksetup' mode." When we find a pseudo_locksetup group, its configuration is expected to be overwritten, we can skip it.

2019-06-08x86/fpu: Update kernel's FPU state before using for the fsave headerSebastian Andrzej Siewior
In commit 39388e80f9b0c ("x86/fpu: Don't save fxregs for ia32 frames in copy_fpstate_to_sigframe()") I removed the statement | if (ia32_fxstate) | copy_fxregs_to_kernel(fpu); and argued that it was wrongly merged because the content was already saved in kernel's state. This was wrong: It is required to write it back because it is only saved on the user-stack and save_fsave_header() reads it from task's FPU-state. I missed that part… Save x87 FPU state unless thread's FPU registers are already up to date.

2019-06-07x86/mm/KASLR: Compute the size of the vmemmap section properlyBaoquan He
The size of the vmemmap section is hardcoded to 1 TB to support the maximum amount of system RAM in 4-level paging mode - 64 TB. However, 1 TB is not enough for vmemmap in 5-level paging mode. Assuming the size of struct page is 64 Bytes, to support 4 PB system RAM in 5-level, 64 TB of vmemmap area is needed: 4 * 1000^5 PB / 4096 bytes page size * 64 bytes per page struct / 1000^4 TB = 62.5 TB. This hardcoding may cause vmemmap to corrupt the following cpu_entry_area section, if KASLR puts vmemmap very close to it and the actual vmemmap size is bigger than 1 TB. So calculate the actual size of the vmemmap region needed and then align it up to 1 TB boundary. In 4-level paging mode it is always 1 TB. In 5-level it's adjusted on demand. The current code reserves 0.5 PB for vmemmap on 5-level. With this change, the space can be saved and thus used to increase entropy for the randomization.

2019-06-06x86/fpu: Use fault_in_pages_writeable() for pre-faultingHugh Dickins
Since commit d9c9ce34ed5c8 ("x86/fpu: Fault-in user stack if copy_fpstate_to_sigframe() fails") get_user_pages_unlocked() pre-faults user's memory if a write generates a page fault while the handler is disabled. This works in general and uncovered a bug as reported by Mike Rapoport¹. It has been pointed out that this function may be fragile and a simple pre-fault as in fault_in_pages_writeable() would be a better solution. Better as in taste and simplicity: that write (as performed by the alternative function) performs exactly the same faulting of memory as before. This was suggested by Hugh Dickins and Andrew Morton. Use fault_in_pages_writeable() for pre-faulting user's stack.
