      afs: proc cells and rootcell are writeable · 1bda2ac0
      Pali Rohár authored
      Both proc files are writeable and used for configuring cells. But
      there is missing correct mode flag for writeable files. Without
      this patch both proc files are read only.
      
      [ It turns out they aren't really read-only, since root can write to
        them even if the write bit isn't set due to CAP_DAC_OVERRIDE ]

      tile: remove compat_sys_lookup_dcookie declaration to fix compile error · 5a5e75f4
      Heiko Carstens authored
      With commit d8d14bd0 ("fs/compat: fix lookup_dcookie() parameter
      handling") I changed the type of the len parameter of the
      lookup_dcookie() syscall.
      
      However I missed that there was still a stale declaration in
      arch/tile/..  which now causes a compile error on tile:
      
        In file included from fs/dcookies.c:28:0:
        include/linux/compat.h:425:17: error: conflicting types for 'compat_sys_lookup_dcookie'
        fs/dcookies.c:207:1: error: conflicting types for 'compat_sys_lookup_dcookie'
      
      Simply remove the declaration in the tile architecture, which is only a
      leftover from before the different compat lookup_dcookie() versions have
      been merged.  The correct declaration is now in include/linux/compat.h
      
      The build error was reported by Fenguang's build bot.

      Revert "PCI: Remove from bus_list and release resources in pci_release_dev()" · 04480094
      Rafael J. Wysocki authored
      Revert commit ef83b078 "PCI: Remove from bus_list and release
      resources in pci_release_dev()" that made some nasty race conditions
      become possible.  For example, if a Thunderbolt link is unplugged
      and then replugged immediately, the pci_release_dev() resulting from
      the hot-remove code path may be racing with the hot-add code path
      which after that commit causes various kinds of breakage to happen
      (up to and including a hard crash of the whole system).
      
      Moreover, the problem that commit ef83b078 attempted to address
      cannot happen any more after commit 8a4c5c32 "PCI: Check parent
      kobject in pci_destroy_dev()", because pci_destroy_dev() will now
      return immediately if it has already been executed for the given
      device.
      
      Note, however, that the invocation of msi_remove_pci_irq_vectors()
      removed by commit ef83b078 from pci_free_resources() along with
      the other changes made by it is not added back because of subsequent
      code changes depending on that modification.

      hfsplus: use xattr handlers for removexattr · b168fff7

      hfsplus was already using the handlers for get and set operations,
      and with the removal of can_set_xattr we've now allow operations that
      wouldn't otherwise be allowed.
      
      With this we can also centralize the special-casing of the osx.

      fs/super.c: sync ro remount after blocking writers · 807612db
      Andrew Ruder authored
      Move sync_filesystem() after sb_prepare_remount_readonly().  If writers
      sneak in anywhere from sync_filesystem() to sb_prepare_remount_readonly()
      it can cause inodes to be dirtied and writeback to occur well after
      sys_mount() has completely successfully.
      
      This was spotted by corrupted ubifs filesystems on reboot, but appears
      that it can cause issues with any filesystem using writeback.

       - The regulator API needs to be told to stay away from things on systems

      alpha: fix broken network checksum · 0ef38d70
      Mikulas Patocka authored
      The patch 3ddc5b46 breaks networking on
      alpha (there is a follow-up fix 5cfe8f1b,
      but networking is still broken even with the second patch).
      
      The patch 3ddc5b46 makes
      csum_partial_copy_from_user check the pointer with access_ok. However,
      csum_partial_copy_from_user is called also from csum_partial_copy_nocheck
      and csum_partial_copy_nocheck is called on kernel pointers and it is
      supposed not to check pointer validity.
      
      This bug results in ssh session hangs if the system is loaded and bulk
      data are printed to ssh terminal.
      
      This patch fixes csum_partial_copy_nocheck to call set_fs(KERNEL_DS), so
      that access_ok in csum_partial_copy_from_user accepts kernel-space
      addresses.

      ALSA: hda/hdmi - allow PIN_OUT to be dynamically enabled · 75fae117
      Stephen Warren authored
      Commit 384a48d7 "ALSA: hda: HDMI: Support codecs with fewer cvts
      than pins" dynamically enabled each pin widget's PIN_OUT only when the
      pin was actively in use. This was required on certain NVIDIA CODECs for
      correct operation. Specifically, if multiple pin widgets each had their
      mux input select the same audio converter widget and each pin widget had
      PIN_OUT enabled, then only one of the pin widgets would actually receive
      the audio, and often not the one the user wanted!
      
      However, this apparently broke some Intel systems, and commit
      6169b673 "ALSA: hda - Always turn on pins for HDMI/DP" reverted the
      dynamic setting of PIN_OUT. This in turn broke the afore-mentioned NVIDIA
      CODECs.
      
      This change supports either dynamic or static handling of PIN_OUT,
      selected by a flag set up during CODEC initialization. This flag is
      enabled for all recent NVIDIA GPUs.

      cifs: Fix check for regular file in couldbe_mf_symlink() · a9a315d4
      Sachin Prabhu authored
      MF Symlinks are regular files containing content in a specified format.
      
      The function couldbe_mf_symlink() checks the mode for a set S_IFREG bit
      as a test to confirm that it is a regular file. This bit is also set for
      other filetypes and simply checking for this bit being set may return
      false positives.
      
      We ensure that we are actually checking for a regular file by using the
      S_ISREG macro to test instead.

      drivers: xen: deaggressive selfballoon driver · bc1b0df5
      Bob Liu authored
      Current xen-selfballoon driver is too aggressive which may cause OOM be
      triggered more often. Eg. this bug reported by James:
      https://lkml.org/lkml/2013/11/21/158
      
      There are two mainly reasons:
      1) The original goal_page didn't consider some pages used by kernel space, like
      slab pages and pages used by device drivers.
      
      2) The balloon driver may not give back memory to guest OS fast enough when the
      workload suddenly aquries a lot of physical memory.
      
      In both cases, the guest OS will suffer from memory pressure and OOM may
      be triggered.
      
      The fix is make xen-selfballoon driver not that aggressive by adding extra 10%
      of total ram pages to goal_page.
      It's more valuable to keep the guest system reliable and response faster than
      balloon out these 10% pages to XEN.

      xen/grant-table: Avoid m2p_override during mapping · 08ece5bb
      Zoltan Kiss authored
      The grant mapping API does m2p_override unnecessarily: only gntdev needs it,
      for blkback and future netback patches it just cause a lock contention, as
      those pages never go to userspace. Therefore this series does the following:
      - the original functions were renamed to __gnttab_[un]map_refs, with a new
        parameter m2p_override
      - based on m2p_override either they follow the original behaviour, or just set
        the private flag and call set_phys_to_machine
      - gnttab_[un]map_refs are now a wrapper to call __gnttab_[un]map_refs with
        m2p_override false
      - a new function gnttab_[un]map_refs_userspace provides the old behaviour
      
      It also removes a stray space from page.h and change ret to 0 if
      XENFEAT_auto_translated_physmap, as that is the only possible return value
      there.
      
      v2:
      - move the storing of the old mfn in page->index to gnttab_map_refs
      - move the function header update to a separate patch
      
      v3:
      - a new approach to retain old behaviour where it needed
      - squash the patches into one
      
      v4:
      - move out the common bits from m2p* functions, and pass pfn/mfn as parameter
      - clear page->private before doing anything with the page, so m2p_find_override
        won't race with this
      
      v5:
      - change return value handling in __gnttab_[un]map_refs
      - remove a stray space in page.h
      - add detail why ret = 0 now at some places
      
      v6:
      - don't pass pfn to m2p* functions, just get it locally

      arm64: mm: Introduce PTE_WRITE · c2c93e5b
      Steve Capper authored
      We have the following means for encoding writable or dirty ptes:
      
                                      PTE_DIRTY       PTE_RDONLY
      !pte_dirty && !pte_write        0               1
      !pte_dirty && pte_write         0               1
      pte_dirty && !pte_write         1               1
      pte_dirty && pte_write          1               0
      
      So we can't distinguish between writable clean ptes and read only
      ptes. This can cause problems with ptes being incorrectly flagged as
      read only when they are writable but not dirty.
      
      This patch introduces a new software bit PTE_WRITE which allows us to
      correctly identify writable ptes. PTE_RDONLY is now only clear for
      valid ptes where a page is both writable and dirty.
