git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull ARM SoC fixes from Olof Johansson: "We had a small batch of fixes before -rc1, but here is a larger one. It contains a backmerge of 4.12-rc1 since some of the downstream branches we merge had that as base; at the same time we already had merged contents before -rc1 and rebase wasn't the right solution. A mix of random smaller fixes and a few things worth pointing out: - We've started telling people to avoid cross-tree shared branches if all they're doing is picking up one or two DT-used constants from a shared include file, and instead to use the numeric values on first submission. Follow-up moving over to symbolic names are sent in right after -rc1, i.e. here. It's only a few minor patches of this type. - Linus Walleij and others are resurrecting the 'Gemini' platform, and wanted a cut-down platform-specific defconfig for it. So I picked that up for them. - Rob Herring ran 'savedefconfig' on arm64, it's a bit churny but it helps people to prepare patches since it's a pain when defconfig and current savedefconfig contents differs too much. - Devicetree additions for some pinctrl drivers for Armada that were merged this window. I'd have preferred to see those earlier but it's not a huge deail. The biggest change worth pointing out though since it's touching other parts of the tree: We added prefixes to be used when cross-including DT contents between arm64 and arm, allowing someone to #include <arm/foo.dtsi> from arm64, and likewise. As part of that, we needed arm/foo.dtsi to work on arm as well. The way I suggested this to Heiko resulted in a recursive symlink. Instead, I've now moved it out of arch/*/boot/dts/include, into a shared location under scripts/dtc. While I was at it, I consolidated so all architectures now behave the same way in this manner. Rob Herring (DT maintainer) has acked it. I cc:d most other arch maintainers but nobody seems to care much; it doesn't really affect them since functionality is unchanged for them by default" * tag 'armsoc-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (29 commits) arm64: dts: rockchip: fix include reference firmware: ti_sci: fix strncat length check ARM: remove duplicate 'const' annotations' arm64: defconfig: enable options needed for QCom DB410c board arm64: defconfig: sync with savedefconfig ARM: configs: add a gemini defconfig devicetree: Move include prefixes from arch to separate directory ARM: dts: dra7: Reduce cpu thermal shutdown temperature memory: omap-gpmc: Fix debug output for access width ARM: dts: LogicPD Torpedo: Fix camera pin mux ARM: dts: omap4: enable CEC pin for Pandaboard A4 and ES ARM: dts: gta04: fix polarity of clocks for mcbsp4 ARM: dts: dra7: Add power hold and power controller properties to palmas soc: imx: add PM dependency for IMX7_PM_DOMAINS ARM: dts: imx6sx-sdb: Remove OPP override ARM: dts: imx53-qsrb: Pulldown PMIC IRQ pin soc: bcm: brcmstb: Correctly match 7435 SoC tee: add ARM_SMCCC dependency ARM: omap2+: make omap4_get_cpu1_ns_pa_addr declaration usable ARM64: dts: mediatek: configure some fixed mmc parameters ...

2017-05-19KVM: X86: Fix read out-of-bounds vulnerability in kvm pio emulationWanpeng Li1-9/+15
Huawei folks reported a read out-of-bounds vulnerability in kvm pio emulation. - "inb" instruction to access PIT Mod/Command register (ioport 0x43, write only, a read should be ignored) in guest can get a random number. - "rep insb" instruction to access PIT register port 0x43 can control memcpy() in emulator_pio_in_emulated() to copy max 0x400 bytes but only read 1 bytes, which will disclose the unimportant kernel memory in host but no crash. The similar test program below can reproduce the read out-of-bounds vulnerability: void hexdump(void *mem, unsigned int len) { unsigned int i, j; for(i = 0; i < len + ((len % HEXDUMP_COLS) ? (HEXDUMP_COLS - len % HEXDUMP_COLS) : 0); i++) { /* print offset */ if(i % HEXDUMP_COLS == 0) { printf("0x%06x: ", i); } /* print hex data */ if(i < len) { printf("%02x ", 0xFF & ((char*)mem)[i]); } else /* end of block, just aligning for ASCII dump */ { printf(" "); } /* print ASCII dump */ if(i % HEXDUMP_COLS == (HEXDUMP_COLS - 1)) { for(j = i - (HEXDUMP_COLS - 1); j <= i; j++) { if(j >= len) /* end of block, not really printing */ { putchar(' '); } else if(isprint(((char*)mem)[j])) /* printable char */ { putchar(0xFF & ((char*)mem)[j]); } else /* other char */ { putchar('.'); } } putchar('\n'); } } } int main(void) { int i; if (iopl(3)) { err(1, "set iopl unsuccessfully\n"); return -1; } static char buf[0x40]; /* test ioport 0x40,0x41,0x42,0x43,0x44,0x45 */ memset(buf, 0xab, sizeof(buf)); asm volatile("push %rdi;"); asm volatile("mov %0, %%rdi;"::"q"(buf)); asm volatile ("mov $0x40, %rdx;"); asm volatile ("in %dx,%al;"); asm volatile ("stosb;"); asm volatile ("mov $0x41, %rdx;"); asm volatile ("in %dx,%al;"); asm volatile ("stosb;"); asm volatile ("mov $0x42, %rdx;"); asm volatile ("in %dx,%al;"); asm volatile ("stosb;"); asm volatile ("mov $0x43, %rdx;"); asm volatile ("in %dx,%al;"); asm volatile ("stosb;"); asm volatile ("mov $0x44, %rdx;"); asm volatile ("in %dx,%al;"); asm volatile ("stosb;"); asm volatile ("mov $0x45, %rdx;"); asm volatile ("in %dx,%al;"); asm volatile ("stosb;"); asm volatile ("pop %rdi;"); hexdump(buf, 0x40); printf("\n"); /* ins port 0x40 */ memset(buf, 0xab, sizeof(buf)); asm volatile("push %rdi;"); asm volatile("mov %0, %%rdi;"::"q"(buf)); asm volatile ("mov $0x20, %rcx;"); asm volatile ("mov $0x40, %rdx;"); asm volatile ("rep insb;"); asm volatile ("pop %rdi;"); hexdump(buf, 0x40); printf("\n"); /* ins port 0x43 */ memset(buf, 0xab, sizeof(buf)); asm volatile("push %rdi;"); asm volatile("mov %0, %%rdi;"::"q"(buf)); asm volatile ("mov $0x20, %rcx;"); asm volatile ("mov $0x43, %rdx;"); asm volatile ("rep insb;"); asm volatile ("pop %rdi;"); hexdump(buf, 0x40); printf("\n"); return 0; } The vcpu->arch.pio_data buffer is used by both in/out instrutions emulation w/o clear after using which results in some random datas are left over in the buffer. Guest reads port 0x43 will be ignored since it is write only, however, the function kernel_pio() can't distigush this ignore from successfully reads data from device's ioport. There is no new data fill the buffer from port 0x43, however, emulator_pio_in_emulated() will copy the stale data in the buffer to the guest unconditionally. This patch fixes it by clearing the buffer before in instruction emulation to avoid to grant guest the stale data in the buffer. In addition, string I/O is not supported for in kernel device. So there is no iteration to read ioport %RCX times for string I/O. The function kernel_pio() just reads one round, and then copy the io size * %RCX to the guest unconditionally, actually it copies the one round ioport data w/ other random datas which are left over in the vcpu->arch.pio_data buffer to the guest. This patch fixes it by introducing the string I/O support for in kernel device in order to grant the right ioport datas to the guest.

Safe access to per-CPU data requires a couple of constraints, though: the thread working with the data cannot be preempted and it cannot be migrated while it manipulates per-CPU variables. If the thread is preempted, the thread that replaces it could try to work with the same variables; migration to another CPU could also cause confusion. However there is no preemption disable when reads host per-CPU tsc rate to calculate the current kvmclock timestamp. This patch fixes it by utilizing get_cpu/put_cpu pair to guarantee both __this_cpu_read() and rdtsc() are not preempted.

2017-05-19i2c: designware: don't infer timings described by ACPI from clock rateArd Biesheuvel1-8/+10
Commit bd698d24b1b57 ("i2c: designware: Get selected speed mode sda-hold-time via ACPI") updated the logic that reads the timing parameters for various I2C bus rates from the DSDT, to only read the timing parameters for the currently selected mode. This causes a WARN_ON() splat on platforms that legally omit the clock frequency from the ACPI description, because in the new situation, the core I2C designware driver still accesses the fields in the driver struct that we no longer populate, and proceeds to calculate them from the clock frequency. Since the clock frequency is unspecified, the driver complains loudly using a WARN_ON(). So revert back to the old situation, where the struct fields for all timings are populated, but retain the new logic which chooses the SDA hold time from the timing mode that is currently in use.

2017-05-19iTCO_wdt: all versions count down twicePaolo Bonzini2-13/+11
The ICH9 is listed as having TCO v2, and indeed the behavior in the datasheet corresponds to v2 (for example the NO_REBOOT flag is accessible via the 16KiB-aligned Root Complex Base Address). However, the TCO counts twice just like in v1; the documentation of the SECOND_TO_STS bit says: "ICH9 sets this bit to 1 to indicate that the TIMEOUT bit had been (or is currently) set and a second timeout occurred before the TCO_RLD register was written. If this bit is set and the NO_REBOOT config bit is 0, then the ICH9 will reboot the system after the second timeout. The same can be found in the BayTrail (Atom E3800) datasheet, and even HOWTOs around the Internet say that it will reboot after _twice_ the specified heartbeat. I did not find the Apollo Lake datasheet, but because v4/v5 has a SECOND_TO_STS bit just like the previous version I'm enabling this for Apollo Lake as well.

2017-05-18devicetree: Move include prefixes from arch to separate directoryOlof Johansson26-11/+16
We use a directory under arch/$ARCH/boot/dts as an include path that has links outside of the subtree to find dt-bindings from under include/dt-bindings. That's been working well, but new DT architectures haven't been adding them by default. Recently there's been a desire to share some of the DT material between arm and arm64, which originally caused developers to create symlinks or relative includes between the subtrees. This isn't ideal -- it breaks if the DT files aren't stored in the exact same hierarchy as the kernel tree, and generally it's just icky. As a somewhat cleaner solution we decided to add a $ARCH/ prefix link once, and allow DTS files to reference dtsi (and dts) files in other architectures that way. Original approach was to create these links under each architecture, but it lead to the problem of recursive symlinks. As a remedy, move the include link directories out of the architecture trees into a common location. At the same time, they can now share one directory and one dt-bindings/ link as well.

2017-05-19powerpc/mm: Fix virt_addr_valid() etc. on 64-bit hashMichael Ellerman1-0/+12
virt_addr_valid() is supposed to tell you if it's OK to call virt_to_page() on an address. What this means in practice is that it should only return true for addresses in the linear mapping which are backed by a valid PFN. We are failing to properly check that the address is in the linear mapping, because virt_to_pfn() will return a valid looking PFN for more or less any address. That bug is actually caused by __pa(), used in virt_to_pfn(). eg: __pa(0xc000000000010000) = 0x10000 # Good __pa(0xd000000000010000) = 0x10000 # Bad! __pa(0x0000000000010000) = 0x10000 # Bad! This started happening after commit bdbc29c19b26 ("powerpc: Work around gcc miscompilation of __pa() on 64-bit") (Aug 2013), where we changed the definition of __pa() to work around a GCC bug. Prior to that we subtracted PAGE_OFFSET from the value passed to __pa(), meaning __pa() of a 0xd or 0x0 address would give you something bogus back. Until we can verify if that GCC bug is no longer an issue, or come up with another solution, this commit does the minimal fix to make virt_addr_valid() work, by explicitly checking that the address is in the linear mapping region.
