2018-08-17ntfs: mft: remove VLA usageKees Cook1-2/+10
In the quest to remove all stack VLA usage from the kernel[1], this allocates the maximum size stack buffer. Existing checks already require that blocksize >= NTFS_BLOCK_SIZE and mft_record_size <= PAGE_SIZE, so max_bhs can be at most PAGE_SIZE / NTFS_BLOCK_SIZE. Sanity checks are added for robustness.

2018-08-17ntfs: decompress: remove VLA usageKees Cook1-12/+16
In the quest to remove all stack VLA usage from the kernel[1], this moves the stack buffer used during decompression to be allocated externally. The existing "dest_max_index" used in the VLA is bounded by cb_max_page. cb_max_page is bounded by max_page, and max_page is bounded by nr_pages. Since nr_pages is used for the "pages" allocation, it can similarly be used for the "completed_pages" allocation and passed into the decompression function. The error paths are updated to free the new allocation.

2018-08-17fs/ntfs/aops.c: don't disable interrupts during kmap_atomic()Sebastian Andrzej Siewior1-4/+0
ntfs_end_buffer_async_read() disables interrupts around kmap_atomic(). This is a leftover from the old kmap_atomic() implementation which relied on fixed mapping slots, so the caller had to make sure that the same slot could not be reused from an interrupting context. kmap_atomic() was changed to dynamic slots long ago and commit 1ec9c5ddc17a ("include/linux/highmem.h: remove the second argument of k[un]map_atomic()") removed the slot assignements, but the callers were not checked for now redundant interrupt disabling. Remove the conditional interrupt disable.

2018-08-17scripts: add Python 3 compatibility to spdxcheck.pyJeremy Cline1-2/+5
"dict.has_key(key)" on dictionaries has been replaced with "key in dict". Additionally, when run under Python 3 some files don't decode with the default encoding (tested with UTF-8). To handle that, don't open the file in text mode and decode text line-by-line, ignoring encoding errors. This remains compatible with Python 2 and should have no functional change.

2018-08-17fs/hpfs: extend gmt_to_local() conversion to 64-bit timesArnd Bergmann2-9/+16
The VFS timestamps are all 64-bit now, the only missing piece for hpfs is the internal conversion function. One interesting bit about hpfs is that it can already deal with moving the 136 year window of its timestamps to support a much wider range than other file systems with 32-bit timestamps. It also treats the timestamps as 'unsigned' on 64-bit architectures (but signed on 32-bit, because time_t always around to negative numbers in 2038). Changing the conversion to use time64_t makes 32-bit architectures behave the same way as 64-bit. For completeness, this also adds a clamp_t call for each conversion, so we don't wrap the timestamps but instead stay within the [0..U32_MAX] range of the on-disk timestamps.

2018-08-17fs/ntfs: use timespec64 directly for timestamp conversionArnd Bergmann2-18/+21
Now that the VFS has been converted from timespec to timespec64 timestamps, only the conversion to/from ntfs timestamps uses 32-bit seconds. This changes that last missing piece to get the ntfs implementation y2038 safe on 32-bit architectures.

2018-08-17fs/ufs: use ktime_get_real_seconds for sb and cg timestampsArnd Bergmann4-5/+19
get_seconds() is deprecated because of the 32-bit overflow and will be removed. All callers in ufs also truncate to a 32-bit number, so nothing changes during the conversion, but this should be harmless as the superblock and cylinder group timestamps are not visible to user space, except for checking the fs-dirty state, wich works fine across the overflow. This moves the call to get_seconds() into a new inline function, with a comment explaining the constraints, while converting it to ktime_get_real_seconds().

2018-08-17firewire: use 64-bit time_t based interfacesArnd Bergmann1-4/+4
32-bit CLOCK_REALTIME timestamps overflow in year 2038, so all such interfaces are deprecated now. For the FW_CDEV_IOC_GET_CYCLE_TIMER2 ioctl, we already support 64-bit timestamps, but the implementation still uses timespec. This changes the code to use timespec64 instead with the appropriate accessor functions.

2018-08-17dax: remove VM_MIXEDMAP for fsdax and device daxDave Jiang11-14/+27
This patch is reworked from an earlier patch that Dan has posted: https://patchwork.kernel.org/patch/10131727/ VM_MIXEDMAP is used by dax to direct mm paths like vm_normal_page() that the memory page it is dealing with is not typical memory from the linear map. The get_user_pages_fast() path, since it does not resolve the vma, is already using {pte,pmd}_devmap() as a stand-in for VM_MIXEDMAP, so we use that as a VM_MIXEDMAP replacement in some locations. In the cases where there is no pte to consult we fallback to using vma_is_dax() to detect the VM_MIXEDMAP special case. Now that we have explicit driver pfn_t-flag opt-in/opt-out for get_user_pages() support for DAX we can stop setting VM_MIXEDMAP. This also means we no longer need to worry about safely manipulating vm_flags in a future where we support dynamically changing the dax mode of a file. DAX should also now be supported with madvise_behavior(), vma_merge(), and copy_page_range(). This patch has been tested against ndctl unit test. It has also been tested against xfstests commit: 625515d using fake pmem created by memmap and no additional issues have been observed.

2018-08-17x86/speculation/l1tf: Exempt zeroed PTEs from inversionSean Christopherson1-1/+10
It turns out that we should *not* invert all not-present mappings, because the all zeroes case is obviously special. clear_page() does not undergo the XOR logic to invert the address bits, i.e. PTE, PMD and PUD entries that have not been individually written will have val=0 and so will trigger __pte_needs_invert(). As a result, {pte,pmd,pud}_pfn() will return the wrong PFN value, i.e. all ones (adjusted by the max PFN mask) instead of zero. A zeroed entry is ok because the page at physical address 0 is reserved early in boot specifically to mitigate L1TF, so explicitly exempt them from the inversion when reading the PFN. Manifested as an unexpected mprotect(..., PROT_NONE) failure when called on a VMA that has VM_PFNMAP and was mmap'd to as something other than PROT_NONE but never used. mprotect() sends the PROT_NONE request down prot_none_walk(), which walks the PTEs to check the PFNs. prot_none_pte_entry() gets the bogus PFN from pte_pfn() and returns -EACCES because it thinks mprotect() is trying to adjust a high MMIO address. [ This is a very modified version of Sean's original patch, but all credit goes to Sean for doing this and also pointing out that sometimes the __pte_needs_invert() function only gets the protection bits, not the full eventual pte. But zero remains special even in just protection bits, so that's ok. - Linus ] Fixes: f22cc87f6c1f ("x86/speculation/l1tf: Invert all not present mappings") Signed-off-by: Sean Christopherson <sean.j.christopherson@intel.com> Acked-by: Andi Kleen <ak@linux.intel.com> Cc: Thomas Gleixner <tglx@linutronix.de> Cc: Josh Poimboeuf <jpoimboe@redhat.com> Cc: Michal Hocko <mhocko@suse.com> Cc: Vlastimil Babka <vbabka@suse.cz> Cc: Dave Hansen <dave.hansen@intel.com> Cc: Greg Kroah-Hartman <gregkh@linuxfoundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

2018-08-17arm64: mm: check for upper PAGE_SHIFT bits in pfn_valid()Greg Hackmann1-1/+5
ARM64's pfn_valid() shifts away the upper PAGE_SHIFT bits of the input before seeing if the PFN is valid. This leads to false positives when some of the upper bits are set, but the lower bits match a valid PFN. For example, the following userspace code looks up a bogus entry in /proc/kpageflags: int pagemap = open("/proc/self/pagemap", O_RDONLY); int pageflags = open("/proc/kpageflags", O_RDONLY); uint64_t pfn, val; lseek64(pagemap, [...], SEEK_SET); read(pagemap, &pfn, sizeof(pfn)); if (pfn & (1UL << 63)) { /* valid PFN */ pfn &= ((1UL << 55) - 1); /* clear flag bits */ pfn |= (1UL << 55); lseek64(pageflags, pfn * sizeof(uint64_t), SEEK_SET); read(pageflags, &val, sizeof(val)); } On ARM64 this causes the userspace process to crash with SIGSEGV rather than reading (1 << KPF_NOPAGE). kpageflags_read() treats the offset as valid, and stable_page_flags() will try to access an address between the user and kernel address ranges.

2018-08-17arm64: Avoid calling stop_machine() when patching jump labelsWill Deacon1-1/+1
Patching a jump label involves patching a single instruction at a time, swizzling between a branch and a NOP. The architecture treats these instructions specially, so a concurrently executing CPU is guaranteed to see either the NOP or the branch, rather than an amalgamation of the two instruction encodings. However, in order to guarantee that the new instruction is visible, it is necessary to send an IPI to the concurrently executing CPU so that it discards any previously fetched instructions from its pipeline. This operation therefore cannot be completed from a context with IRQs disabled, but this is exactly what happens on the jump label path where the hotplug lock is held and irqs are subsequently disabled by stop_machine_cpuslocked(). This results in a deadlock during boot on Hikey-960. Due to the architectural guarantees around patching NOPs and branches, we don't actually need to stop_machine() at all on the jump label path, so we can avoid the deadlock by using the "nosync" variant of our instruction patching routine.

git://git.kernel.org/pub/scm/linux/kernel/git/jmorris/linux-security Pull TPM updates from James Morris: - Migrate away from PM runtime as explicit cmdReady/goIdle transactions for every command is a spec requirement. PM runtime adds only a layer of complexity on our case. - tpm_tis drivers can now specify the hwrng quality. - TPM 2.0 code uses now tpm_buf for constructing messages. Jarkko thinks Tomas Winkler has done the same for TPM 1.2, and will start digging those changes from the patchwork in the near future. - Bug fixes and clean ups * 'next-tpm' of git://git.kernel.org/pub/scm/linux/kernel/git/jmorris/linux-security: ima: Get rid of ima_used_chip and use ima_tpm_chip != NULL instead ima: Use tpm_default_chip() and call TPM functions with a tpm_chip tpm: replace TPM_TRANSMIT_RAW with TPM_TRANSMIT_NESTED tpm: Convert tpm_find_get_ops() to use tpm_default_chip() tpm: Implement tpm_default_chip() to find a TPM chip tpm: rename tpm_chip_find_get() to tpm_find_get_ops() tpm: Allow tpm_tis drivers to set hwrng quality. tpm: Return the actual size when receiving an unsupported command tpm: separate cmd_ready/go_idle from runtime_pm tpm/tpm_i2c_infineon: switch to i2c_lock_bus(..., I2C_LOCK_SEGMENT) tpm_tis_spi: Pass the SPI IRQ down to the driver tpm: migrate tpm2_get_random() to use struct tpm_buf tpm: migrate tpm2_get_tpm_pt() to use struct tpm_buf tpm: migrate tpm2_probe() to use struct tpm_buf tpm: migrate tpm2_shutdown() to use struct tpm_buf
