33c9e97 Linus Torvalds 22 May 2017, 01:26:54 UTC x86: fix 32-bit case of __get_user_asm_u64() The code to fetch a 64-bit value from user space was entirely buggered, and has been since the code was merged in early 2016 in commit b2f680380ddf ("x86/mm/32: Add support for 64-bit __get_user() on 32-bit kernels"). Happily the buggered routine is almost certainly entirely unused, since the normal way to access user space memory is just with the non-inlined "get_user()", and the inlined version didn't even historically exist. The normal "get_user()" case is handled by external hand-written asm in arch/x86/lib/getuser.S that doesn't have either of these issues. There were two independent bugs in __get_user_asm_u64(): - it still did the STAC/CLAC user space access marking, even though that is now done by the wrapper macros, see commit 11f1a4b9755f ("x86: reorganize SMAP handling in user space accesses"). This didn't result in a semantic error, it just means that the inlined optimized version was hugely less efficient than the allegedly slower standard version, since the CLAC/STAC overhead is quite high on modern Intel CPU's. - the double register %eax/%edx was marked as an output, but the %eax part of it was touched early in the asm, and could thus clobber other inputs to the asm that gcc didn't expect it to touch. In particular, that meant that the generated code could look like this: mov (%eax),%eax mov 0x4(%eax),%edx where the load of %edx obviously was _supposed_ to be from the 32-bit word that followed the source of %eax, but because %eax was overwritten by the first instruction, the source of %edx was basically random garbage. The fixes are trivial: remove the extraneous STAC/CLAC entries, and mark the 64-bit output as early-clobber to let gcc know that no inputs should alias with the output register.

334a023 Linus Torvalds 21 May 2017, 22:25:46 UTC Clean up x86 unsafe_get/put_user() type handling Al noticed that unsafe_put_user() had type problems, and fixed them in commit a7cc722fff0b ("fix unsafe_put_user()"), which made me look more at those functions. It turns out that unsafe_get_user() had a type issue too: it limited the largest size of the type it could handle to "unsigned long". Which is fine with the current users, but doesn't match our existing normal get_user() semantics, which can also handle "u64" even when that does not fit in a long. While at it, also clean up the type cast in unsafe_put_user(). We actually want to just make it an assignment to the expected type of the pointer, because we actually do want warnings from types that don't convert silently. And it makes the code more readable by not having that one very long and complex line. [ This patch might become stable material if we ever end up back-porting any new users of the unsafe uaccess code, but as things stand now this doesn't matter for any current existing uses. ] Cc: Al Viro <viro@zeniv.linux.org.uk> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> 21 May 2017, 22:25:46 UTC

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.

cbfc6c9 Wanpeng Li 19 May 2017, 09:46:56 UTC KVM: X86: Fix read out-of-bounds vulnerability in kvm pio emulation 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.

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.

1fccb73 Paolo Bonzini 05 April 2017, 11:41:15 UTC iTCO_wdt: all versions count down twice 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.

A run of sparse revealed a couple of endianness issues that are now fixed, and addressed is also a user-triggerable division-by-zero in io_ti when debugging is enabled. Finally there are some new device ids, including a simplification of how we deal with a couple of older Olimex JTAG adapters. All have been in linux-next with no reported issues.

d5d332d Olof Johansson 13 May 2017, 03:13:26 UTC devicetree: Move include prefixes from arch to separate directory 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.

e41e53c Michael Ellerman 18 May 2017, 10:37:31 UTC powerpc/mm: Fix virt_addr_valid() etc. on 64-bit hash 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.

It circumvents the existing STRICT_DEVMEM permission check because the loop immediately terminates (as the start address is already higher than the end address). On the x86_64 architecture it will then cause a panic (from the BUG(start >= end) in arch/x86/mm/pat.c:reserve_memtype()).

This seems to be caused by the fact that now phy is enabled earlier, and we are wrongly trying to force USB host mode on an OTG port. The errors we are getting are "trying to suspend as a_idle while active". For ports configured as OTG, we should not need to do anything to try to force USB host mode on it's OTG port. Trying to force host mode in this case just seems to completely confuse the musb state machine. Let's fix the issue by making musb_host_setup() attempt to force the mode only if port_mode is configured for host mode.
