      rtlwifi: Fix fallback firmware loading · 4870e166
      Sven Joachim authored
      commit 1d9b168d upstream.
      
      Commit f70e4df2 ("rtlwifi: Add code to read new versions of
      firmware") added code to load an old firmware file if the new one is
      not available.  Unfortunately that code is never reached because
      request_firmware_nowait() does not wait for the firmware to show up
      and returns 0 even if the file is not there.
      
      Use the existing fallback mechanism introduced by commit 62009b7f
      ("rtlwifi: rtl8192cu: Add new firmware") instead.

      of/device: Prevent buffer overflow in of_device_modalias() · d29e6c2a
      Bjorn Andersson authored
      commit 08ab58d9 upstream.
      
      As of_device_get_modalias() returns the number of bytes that would have
      been written to the target string, regardless of how much did fit in the
      buffer, it's possible that the returned index points beyond the buffer
      passed to of_device_modalias() - causing memory beyond the buffer to be
      null terminated.

      scsi: sg: recheck MMAP_IO request length with lock held · 9cbbaf10
      Todd Poynor authored
      commit 8d26f491 upstream.
      
      Commit 1bc0eb04 ("scsi: sg: protect accesses to 'reserved' page
      array") adds needed concurrency protection for the "reserve" buffer.
      Some checks that are initially made outside the lock are replicated once
      the lock is taken to ensure the checks and resulting decisions are made
      using consistent state.
      
      The check that a request with flag SG_FLAG_MMAP_IO set fits in the
      reserve buffer also needs to be performed again under the lock to ensure
      the reserve buffer length compared against matches the value in effect
      when the request is linked to the reserve buffer.  An -ENOMEM should be
      returned in this case, instead of switching over to an indirect buffer
      as for non-MMAP_IO requests.

      scsi: sg: protect against races between mmap() and SG_SET_RESERVED_SIZE · 200afc40
      Todd Poynor authored
      commit 6a8dadcc upstream.
      
      Take f_mutex around mmap() processing to protect against races with the
      SG_SET_RESERVED_SIZE ioctl.  Ensure the reserve buffer length remains
      consistent during the mapping operation, and set the "mmap called" flag
      to prevent further changes to the reserved buffer size as an atomic
      operation with the mapping.

      commit 591b6bb6 upstream.
      
      Several legacy devices such as Geode-based Cisco ASA appliances
      and DB800 development board do possess CS5536 IDE controller
      with different PCI id than existing one. Using pata_generic is
      not always feasible as at least DB800 requires MSR quirk from
      pata_cs5536 to be used with vendor firmware.

      drm/nouveau/pci/msi: disable MSI on big-endian platforms by default · a6034956
      Ilia Mirkin authored
      commit bc60c90f upstream.
      
      It appears that MSI does not work on either G5 PPC nor on a E5500-based
      platform, where other hardware is reported to work fine with MSI.
      
      Both tests were conducted with NV4x hardware, so perhaps other (or even
      this) hardware can be made to work. It's still possible to force-enable
      with config=NvMSI=1 on load.

      s390/mm: avoid empty zero pages for KVM guests to avoid postcopy hangs · e0441819
      Christian Borntraeger authored
      commit fa41ba0d upstream.
      
      Right now there is a potential hang situation for postcopy migrations,
      if the guest is enabling storage keys on the target system during the
      postcopy process.
      
      For storage key virtualization, we have to forbid the empty zero page as
      the storage key is a property of the physical page frame.  As we enable
      storage key handling lazily we then drop all mappings for empty zero
      pages for lazy refaulting later on.
      
      This does not work with the postcopy migration, which relies on the
      empty zero page never triggering a fault again in the future. The reason
      is that postcopy migration will simply read a page on the target system
      if that page is a known zero page to fault in an empty zero page.  At
      the same time postcopy remembers that this page was already transferred
      - so any future userfault on that page will NOT be retransmitted again
      to avoid races.
      
      If now the guest enters the storage key mode while in postcopy, we will
      break this assumption of postcopy.
      
      The solution is to disable the empty zero page for KVM guests early on
      and not during storage key enablement. With this change, the postcopy
      migration process is guaranteed to start after no zero pages are left.
      
      As guest pages are very likely not empty zero pages anyway the memory
      overhead is also pretty small.
      
      While at it this also adds proper page table locking to the zero page
      removal.

      mwifiex: correct channel stat buffer overflows · 24bb35f2
      Brian Norris authored
      commit 4b5dde2d upstream.
      
      mwifiex records information about various channels as it receives scan
      information. It does this by appending to a buffer that was sized
      to the max number of supported channels on any band, but there are
      numerous problems:
      
      (a) scans can return info from more than one band (e.g., both 2.4 and 5
          GHz), so the determined "max" is not large enough
      (b) some firmware appears to return multiple results for a given
          channel, so the max *really* isn't large enough
      (c) there is no bounds checking when stashing these stats, so problems
          (a) and (b) can easily lead to buffer overflows
      
      Let's patch this by setting a slightly-more-correct max (that accounts
      for a combination of both 2.4G and 5G bands) and adding a bounds check
      when writing to our statistics buffer.
      
      Due to problem (b), we still might not properly report all known survey
      information (e.g., with "iw <dev> survey dump"), since duplicate results
      (or otherwise "larger than expected" results) will cause some
      truncation. But that's a problem for a future bugfix.
      
      (And because of this known deficiency, only log the excess at the WARN
      level, since that isn't visible by default in this driver and would
      otherwise be a bit too noisy.)

      dlm: avoid double-free on error path in dlm_device_{register,unregister} · 6b42a3cc
      Edwin Török authored
      commit 55acdd92 upstream.
      
      Can be reproduced when running dlm_controld (tested on 4.4.x, 4.12.4):
       # seq 1 100 | xargs -P0 -n1 dlm_tool join
       # seq 1 100 | xargs -P0 -n1 dlm_tool leave
      
      misc_register fails due to duplicate sysfs entry, which causes
      dlm_device_register to free ls->ls_device.name.
      In dlm_device_deregister the name was freed again, causing memory
      corruption.
      
      According to the comment in dlm_device_deregister the name should've been
      set to NULL when registration fails,
      so this patch does that.

      rtlwifi: rtl_pci_probe: Fix fail path of _rtl_pci_find_adapter · 3d9dc09e
      Malcolm Priestley authored
      commit fc81bab5 upstream.
      
      _rtl_pci_find_adapter fail path will jump to label fail3 for
      unsupported adapter types.
      
      However, on course for fail3 there will be call rtl_deinit_core
      before rtl_init_core.
      
      For the inclusion of checking pci_iounmap this fail can be moved to
      fail2.
      
      Fixes
