      Richard Leitner authored
      commit 0224ec9e upstream.
      
      Fix the format string for serio device name generation to avoid negative
      device numbers when the id exceeds the maximum signed integer value.

      Input: xpad - add VID/PID for Razer Sabertooth · d73acdbb
      Frank Razenberg authored
      commit a7b44738 upstream.
      
      The xpad driver recognizes Razer Sabertooth controllers as generic xbox
      controller, while it is really a 360 controller.  This patch adds pid/vid
      mappings for the controller so that it is correctly recognized.

      Bluetooth: Fix crash in the Marvell driver initialization codepath · a7b25652
      Anatol Pomozov authored
      commit 8500d791 upstream.
      
      btmrvl_add_card() function calls kthread_run that might return error
      (e.g. if current thread is killed). If one tries to use the error
      value as a pointer then invalid memory access oops happens.
      
      Check kthread_run() return value, if it is an error then release resources
      correctly.
      
      TEST=boot computer with BT modules enabled. I see the error message that
      BT device initialization failed. Now kernel does not crash. Hint: to enable
      BT run 'rmmod btmrvl_sdio; modprobe btmrvl_sdio'

      Bluetooth: Fix endian and alignment issue with ath3k version handling · 0c557568
      Marcel Holtmann authored
      commit 72dd2b2a upstream.
      
      The ath3k driver is treating the version information badly when it
      comes to loading the right firmware version and comparing that it
      actually matches with the hardware.
      
      Initially this showed up as this:
      
        CHECK   drivers/bluetooth/ath3k.c
      drivers/bluetooth/ath3k.c:373:17: warning: cast to restricted __le32
      drivers/bluetooth/ath3k.c:435:17: warning: cast to restricted __le32
      
      However when fixing this by actually using __packed and __le32 for
      the ath3_version structure, more issues came up:
      
        CHECK   drivers/bluetooth/ath3k.c
      drivers/bluetooth/ath3k.c:381:32: warning: incorrect type in assignment (different base types)
      drivers/bluetooth/ath3k.c:381:32:    expected restricted __le32 [usertype] rom_version
      drivers/bluetooth/ath3k.c:381:32:    got int [signed] <noident>
      drivers/bluetooth/ath3k.c:382:34: warning: incorrect type in assignment (different base types)
      drivers/bluetooth/ath3k.c:382:34:    expected restricted __le32 [usertype] build_version
      drivers/bluetooth/ath3k.c:382:34:    got int [signed] <noident>
      drivers/bluetooth/ath3k.c:386:28: warning: restricted __le32 degrades to integer
      drivers/bluetooth/ath3k.c:386:56: warning: restricted __le32 degrades to integer
      
      This patch fixes every instance of the firmware version handling and
      makes sure it is endian safe and uses proper unaligned access.

      Bluetooth: Ignore isochronous endpoints for Intel USB bootloader · cfe9113b
      Marcel Holtmann authored
      commit d92f2df0 upstream.
      
      The isochronous endpoints are not valid when the Intel Bluetooth
      controller boots up in bootloader mode. So just mark these endpoints
      as broken and then they will not be configured.

      Bluetooth: Add support for Intel bootloader devices · b8405fb6
      Marcel Holtmann authored
      commit 40df783d upstream.
      
      Intel Bluetooth devices that boot up in bootloader mode can not
      be used as generic HCI devices, but their HCI transport is still
      valuable and so bring that up as raw-only devices.

      HID: usbhid: Use flag HID_DISCONNECTED when a usb device is removed · 0948a8e2

      commit 46df9ded upstream.
      
      Set disconnected flag in struct usbhid when a usb device is removed. Check for
      disconnected flag before sending urb requests. This prevents a kernel panic
      when a hid driver calls hid_hw_request() after removing a usb device.

      arm64/crypto: fix makefile rule for aes-glue-%.o · d9d8d655
      Andreas Schwab authored
      commit 7c2105fb upstream.
      
      This fixes the following build failure when building with CONFIG_MODVERSIONS
      enabled:
      
        CC [M]  arch/arm64/crypto/aes-glue-ce.o

      make: *** [arch/arm64/crypto] Error 2
      
      The $(obj)/aes-glue-%.o rule only creates $(obj)/.tmp_aes-glue-ce.o, it
      should use if_changed_rule instead of if_changed_dep.

      ARM: pxa: fix hang on startup with DEBUG_LL · c6f4b45b
      Robert Jarzmik authored
      commit cde7fc87 upstream.
      
      The commit 2111667b ("ARM: pxa: call debug_ll_io_init for
      earlyprintk") triggers in the current kernel the attached backtrace on
      PXA/tosa early in the boot time when DEBUG_LL is enabled.
      
      It is due to overlap between uart virtual memory defined in
      DEBUG_UART_VIRT and mapped by debug_ll_io_init() and peripheral bus
      mapped by pxa_map_io at the same address, 0xf2100000.
      
      As hinted by Arnd, map early virtual memory for low level debug on
      address 0xf6200000, even if that means 2 virtual mappings will give
      access to the pxa internal UARTs (FFUART, BTUART, STUART, ...).

      vfs: Don't exchange "short" filenames unconditionally. · f1052d21
      Mikhail Efremov authored
      commit d2fa4a84 upstream.
      
      Only exchange source and destination filenames
      if flags contain RENAME_EXCHANGE.
      In case if executable file was running and replaced by
      other file /proc/PID/exe should still show correct file name,
      not the old name of the file by which it was replaced.
      
      The scenario when this bug manifests itself was like this:
      * ALT Linux uses rpm and start-stop-daemon;
      * during a package upgrade rpm creates a temporary file
        for an executable to rename it upon successful unpacking;
      * start-stop-daemon is run subsequently and it obtains
        the (nonexistant) temporary filename via /proc/PID/exe
        thus failing to identify the running process.
      
      Note that "long" filenames (> DNAiME_INLINE_LEN) are still
      exchanged without RENAME_EXCHANGE and this behaviour exists
      long enough (should be fixed too apparently).
      So this patch is just an interim workaround that restores
      behavior for "short" names as it was before changes
      introduced by commit da1ce067 ("vfs: add cross-rename").
      
      See https://lkml.org/lkml/2014/9/7/6 for details.
      
      AV: the comments about being more careful with ->d_name.hash
      than with ->d_name.name are from back in 2.3.40s; they
      became obsolete by 2.3.60s, when we started to unhash the
      target instead of swapping hash chain positions followed
      by d_delete() as we used to do when dcache was first
      introduced.

      x86_64, traps: Stop using IST for #SS · 09f581ba
      Andy Lutomirski authored
      commit 6f442be2 upstream.
      
      On a 32-bit kernel, this has no effect, since there are no IST stacks.
      
      On a 64-bit kernel, #SS can only happen in user code, on a failed iret
      to user space, a canonical violation on access via RSP or RBP, or a
      genuine stack segment violation in 32-bit kernel code.  The first two
      cases don't need IST, and the latter two cases are unlikely fatal bugs,
      and promoting them to double faults would be fine.
      
      This fixes a bug in which the espfix64 code mishandles a stack segment
      violation.
      
      This saves 4k of memory per CPU and a tiny bit of code.
