2019-06-23lkdtm: Check for SMEP clearing protectionsKees Cook3-0/+68
This adds an x86-specific test for pinned cr4 bits. A successful test will validate pinning and check the ROP-style call-middle-of-function defense, if needed. For example, in the case of native_write_cr4() looking like this: ffffffff8171bce0 <native_write_cr4>: ffffffff8171bce0: 48 8b 35 79 46 f2 00 mov 0xf24679(%rip),%rsi ffffffff8171bce7: 48 09 f7 or %rsi,%rdi ffffffff8171bcea: 0f 22 e7 mov %rdi,%cr4 ... ffffffff8171bd5a: c3 retq The UNSET_SMEP test will jump to ffffffff8171bcea (the mov to cr4) instead of ffffffff8171bce0 (native_write_cr4() entry) to simulate a direct-call bypass attempt. Expected successful results: # echo UNSET_SMEP > /sys/kernel/debug/provoke-crash/DIRECT # dmesg [ 79.594433] lkdtm: Performing direct entry UNSET_SMEP [ 79.596459] lkdtm: trying to clear SMEP normally [ 79.598406] lkdtm: ok: SMEP did not get cleared [ 79.599981] lkdtm: trying to clear SMEP with call gadget [ 79.601810] ------------[ cut here ]------------ [ 79.603421] Attempt to unpin cr4 bits: 100000; bypass attack?! ...

That should be introduced by commit: 7560cc3ca7d9 ("iommu/vt-d: Fix lock inversion between iommu->lock and device_domain_lock", 2019-05-27) So far I still cannot figure out how the previous deadlock was triggered (I cannot find iommu lock taken before calling of iommu_flush_dev_iotlb()), however I'm pretty sure that that change should be incomplete at least because it does not fix all the places so we're still taking the locks in different orders, while reverting that commit is very clean to me so far that we should always take device_domain_lock first then the iommu lock. We can continue to try to find the real culprit mentioned in 7560cc3ca7d9, but for now I think we should revert it to fix current breakage.

git://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux Pull powerpc fixes from Michael Ellerman: "This is a frustratingly large batch at rc5. Some of these were sent earlier but were missed by me due to being distracted by other things, and some took a while to track down due to needing manual bisection on old hardware. But still we clearly need to improve our testing of KVM, and of 32-bit, so that we catch these earlier. Summary: seven fixes, all for bugs introduced this cycle. - The commit to add KASAN support broke booting on 32-bit SMP machines, due to a refactoring that moved some setup out of the secondary CPU path. - A fix for another 32-bit SMP bug introduced by the fast syscall entry implementation for 32-bit BOOKE. And a build fix for the same commit. - Our change to allow the DAWR to be force enabled on Power9 introduced a bug in KVM, where we clobber r3 leading to a host crash. - The same commit also exposed a previously unreachable bug in the nested KVM handling of DAWR, which could lead to an oops in a nested host. - One of the DMA reworks broke the b43legacy WiFi driver on some people's powermacs, fix it by enabling a 30-bit ZONE_DMA on 32-bit. - A fix for TLB flushing in KVM introduced a new bug, as it neglected to also flush the ERAT, this could lead to memory corruption in the guest.

2019-06-22Bluetooth: Fix regression with minimum encryption key size alignmentMarcel Holtmann2-14/+37
When trying to align the minimum encryption key size requirement for Bluetooth connections, it turns out doing this in a central location in the HCI connection handling code is not possible. Original Bluetooth version up to 2.0 used a security model where the L2CAP service would enforce authentication and encryption. Starting with Bluetooth 2.1 and Secure Simple Pairing that model has changed into that the connection initiator is responsible for providing an encrypted ACL link before any L2CAP communication can happen. Now connecting Bluetooth 2.1 or later devices with Bluetooth 2.0 and before devices are causing a regression. The encryption key size check needs to be moved out of the HCI connection handling into the L2CAP channel setup. To achieve this, the current check inside hci_conn_security() has been moved into l2cap_check_enc_key_size() helper function and then called from four decisions point inside L2CAP to cover all combinations of Secure Simple Pairing enabled devices and device using legacy pairing and legacy service security model.

2019-06-21x86/vdso: Prevent segfaults due to hoisted vclock readsAndy Lutomirski1-2/+13
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.

We can end up in nfs4_opendata_alloc during task exit, in which case current->fs has already been cleaned up. This leads to a crash in current_umask(). Fix this by only setting creation opendata if we are actually doing an open with O_CREAT. We can drop the check for NULL nfs4_open_createattrs, since O_CREAT will never be set for the recovery path.

2019-06-21VMCI: Fix integer overflow in VMCI handle arraysVishnu DASA4-59/+99
The VMCI handle array has an integer overflow in vmci_handle_arr_append_entry when it tries to expand the array. This can be triggered from a guest, since the doorbell link hypercall doesn't impose a limit on the number of doorbell handles that a VM can create in the hypervisor, and these handles are stored in a handle array. In this change, we introduce a mandatory max capacity for handle arrays/lists to avoid excessive memory usage.

2019-06-21ARM: 8867/1: vdso: pass --be8 to linker if necessaryJason A. Donenfeld1-2/+3
The commit fe00e50b2db8 ("ARM: 8858/1: vdso: use $(LD) instead of $(CC) to link VDSO") removed the passing of CFLAGS, since ld doesn't take those directly. However, prior, big-endian ARM was relying on gcc to translate its -mbe8 option into ld's --be8 option. Lacking this, ld generated be32 code, making the VDSO generate SIGILL when called by userspace. This commit passes --be8 if CONFIG_CPU_ENDIAN_BE8 is enabled. Signed-off-by: Jason A.
