According to NXP Reference Manuals and uboot/atf sources the OCOTP block on imx8m behaves more like imx6 than imx7. - Fuses can be read/written 32bits at a time (no imx7-like banking) - The OCOTP_HW_OCOTP_TIMING register is like imx6 not imx7 Since nvmem doesn't support uboot-style "sense" and "override" this issue only affected "write" which is very rarely used.

This patch adds support to burn the fuses on the i.MX8MM. https://www.nxp.com/webapp/Download?colCode=IMX8MMRM The i.MX8MM is similar to i.MX6 processors in terms of addressing and clock setup. The documentation specifies 60 discreet OTP registers but, the fusemap address space encompasses up to 256 registers. We map the entire putative 256 OTP registers.

The RELAX field of the OCOTP block is turning out as a zero on i.MX8MM. This messes up the subsequent re-load of the fuse shadow registers. After some discussion with people @ NXP its clear we have missed a trick here in Linux. The OCOTP fuse programming time has a physical minimum 'burn time' that is not related to the ipg_clk. We need to define the RELAX, STROBE_READ and STROBE_PROG fields in terms of desired timings to allow for the burn-in to safely complete. Right now only the RELAX field is calculated in terms of an absolute time and we are ending up with a value of zero. This patch inherits the u-boot timings for the OCOTP_TIMING calculation on the i.MX6 and i.MX8. Those timings are known to work and critically specify values such as STROBE_PROG as a minimum timing.

The i.MX6 and i.MX8 both have a bit-field spanning bits 27:22 called the WAIT field. The WAIT field according to the documentation for both parts "specifies time interval between auto read and write access in one time program. It is given in number of ipg_clk periods." This patch ensures that the relevant field is read and written back to the timing register.

i.MX6 defines OCOTP_CTRLn:ADDR as seven bit address-field with a one bit RSVD0 field, i.MX7 defines OCOTP_CTRLn:ADDR as a four bit address-field with a four bit RSVD0 field. i.MX8 defines the OCOTP_CTRLn:ADDR bit-field as a full range eight bits. i.MX6 and i.MX7 should return zero for their respective RSVD0 bits and ignore a write-back of zero where i.MX8 will make use of the full range. This patch expands the bit-field definition for all users to eight bits, which is safe due to RSVD0 being a no-op for the i.MX6 and i.MX7.

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: 7560cc3c ("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 7560cc3c, but for now I think we should revert it to fix current breakage.

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.

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.

They're still fixes, but they're more complex issues like livelock under heavy load where the answer was to change work queue usage and spinlock usage to resolve the problem, or issues with orphaned requests during certain types of failures like link down which required some more complex work to fix too.

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 459e3a21 ("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.

Pull still more SPDX updates from Greg KH: "Another round of SPDX updates for 5.2-rc6 Here is what I am guessing is going to be the last "big" SPDX update for 5.2. It contains all of the remaining GPLv2 and GPLv2+ updates that were "easy" to determine by pattern matching. The ones after this are going to be a bit more difficult and the people on the spdx list will be discussing them on a case-by-case basis now. Another 5000+ files are fixed up, so our overall totals are: Files checked: 64545 Files with SPDX: 45529 Compared to the 5.1 kernel which was: Files checked: 63848 Files with SPDX: 22576 This is a huge improvement.

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.
