      ntb_perf: potential info leak in debugfs · 819baf88
      Dan Carpenter 提交于
      This is a static checker warning, not something I'm desperately
      concerned about.  But snprintf() returns the number of bytes that
      would have been copied if there were space.  We really care about the
      number of bytes that actually were copied so we should use scnprintf()
      instead.
      
      It probably won't overrun, and in that case we may as well just use
      sprintf() but these sorts of things make static checkers and code
      reviewers happier.

      ntb: ntb_hw_intel: init peer_addr in struct intel_ntb_dev · 25ea9f2b
      Dave Jiang 提交于
      The peer_addr member of intel_ntb_dev is not set, therefore when
      acquiring ntb_peer_db and ntb_peer_spad we only get the offset rather
      than the actual physical address. Adding fix to correct that.

        The last patch on this series is actually not related to DMA on stack.
        It solves a longstanding bug affecting module unload, causing
        module_put() to be called twice. It was reported by the user who
        reported and tested the issues with the gp8psk driver with the DMA
        fixup patches. As we're late at -rc cycle, maybe you prefer to not
        apply it right now. If this is the case, I'll add to the pile of
        patches for 4.10.

      iio: maxim_thermocouple: detect invalid storage size in read() · d70674ee
      Arnd Bergmann 提交于
      As found by gcc -Wmaybe-uninitialized, having a storage_bytes value other
      than 2 or 4 will result in undefined behavior:
      
      drivers/iio/temperature/maxim_thermocouple.c: In function 'maxim_thermocouple_read':
      drivers/iio/temperature/maxim_thermocouple.c:141:5: error: 'ret' may be used uninitialized in this function [-Werror=maybe-uninitialized]
      
      This probably cannot happen, but returning -EINVAL here is appropriate
      and makes gcc happy and the code more robust.

      x86/efi: Prevent mixed mode boot corruption with CONFIG_VMAP_STACK=y · f6697df3
      Matt Fleming 提交于
      Booting an EFI mixed mode kernel has been crashing since commit:
      
        e37e43a4 ("x86/mm/64: Enable vmapped stacks (CONFIG_HAVE_ARCH_VMAP_STACK=y)")
      
      The user-visible effect in my test setup was the kernel being unable
      to find the root file system ramdisk. This was likely caused by silent
      memory or page table corruption.
      
      Enabling CONFIG_DEBUG_VIRTUAL=y immediately flagged the thunking code as
      abusing virt_to_phys() because it was passing addresses that were not
      part of the kernel direct mapping.
      
      Use the slow version instead, which correctly handles all memory
      regions by performing a page table walk.

      x86/efi: Fix EFI memmap pointer size warning · 02e56902
      Borislav Petkov 提交于
      Fix this when building on 32-bit:
      
        arch/x86/platform/efi/efi.c: In function ‘__efi_enter_virtual_mode’:
        arch/x86/platform/efi/efi.c:911:5: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast]
             (efi_memory_desc_t *)pa);
             ^
        arch/x86/platform/efi/efi.c:918:5: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast]
             (efi_memory_desc_t *)pa);
             ^
      
      The @pa local variable is declared as phys_addr_t and that is a u64 when
      CONFIG_PHYS_ADDR_T_64BIT=y. (The last is enabled on 32-bit on a PAE
      build.)
      
      However, its value comes from __pa() which is basically doing pointer
      arithmetic and checking, and returns unsigned long as it is the native
      pointer width.
      
      So let's use an unsigned long too. It should be fine to do so because
      the later users cast it to a pointer too.
