      ALSA: hda - Check leaf nodes to find aamix amps · 2ded3e5b
      Takashi Iwai authored
      The current generic parser assumes blindly that the volume and mute
      amps are found in the aamix node itself.  But on some codecs,
      typically Analog Devices ones, the aamix amps are separately
      implemented in each leaf node of the aamix node, and the current
      driver can't establish the correct amp controls.  This is a regression
      compared with the previous static quirks.
      This patch extends the search for the amps to the leaf nodes for
      allowing the aamix controls again on such codecs.
      In this implementation, I didn't code to loop through the whole paths,
      since usually one depth should suffice, and we can't search too
      deeply, as it may result in the conflicting control assignments.

       - The value of FDF is sfc.
       - The packet includes only CIP headers
      Way 2. a special non-empty packet defined in IEC 61883-6
       - Size of packet is following to blocking mode
       - The value of FDF is 0xff. This value is 'NO-DATA'. This means 'The receiver'
         must ignore all the data in a CIP with this FDF code'.
       - The packet includes dummy data.
      But current implementation is a combination of them.
       - Size of packet is 2 (way 1)
       - FDF = 0xff (way 2)
      This causes BeBoB chipset cannot sound.
      This patch applies Way 1.

      Pull security subsystem updates from James Morris:
       "In this patchset, we finally get an SELinux update, with Paul Moore
        taking over as maintainer of that code.
        Also a significant update for the Keys subsystem, as well as
        maintenance updates to Smack, IMA, TPM, and Apparmor"
      and since I wanted to know more about the updates to key handling,
      here's the explanation from David Howells on that:
       "Okay.  There are a number of separate bits.  I'll go over the big bits
        and the odd important other bit, most of the smaller bits are just
        fixes and cleanups.  If you want the small bits accounting for, I can
        do that too.
         (1) Keyring capacity expansion.
              KEYS: Consolidate the concept of an 'index key' for key access
              KEYS: Introduce a search context structure
              KEYS: Search for auth-key by name rather than target key ID
              Add a generic associative array implementation.
              KEYS: Expand the capacity of a keyring
           Several of the patches are providing an expansion of the capacity of a
           keyring.  Currently, the maximum size of a keyring payload is one page.
           Subtract a small header and then divide up into pointers, that only gives
           you ~500 pointers on an x86_64 box.  However, since the NFS idmapper uses
           a keyring to store ID mapping data, that has proven to be insufficient to
           the cause.
           Whatever data structure I use to handle the keyring payload, it can only
           store pointers to keys, not the keys themselves because several keyrings
           may point to a single key.  This precludes inserting, say, and rb_node
           struct into the key struct for this purpose.
           I could make an rbtree of records such that each record has an rb_node
           and a key pointer, but that would use four words of space per key stored
           in the keyring.  It would, however, be able to use much existing code.
           I selected instead a non-rebalancing radix-tree type approach as that
           could have a better space-used/key-pointer ratio.  I could have used the
           radix tree implementation that we already have and insert keys into it by
           their serial numbers, but that means any sort of search must iterate over
           the whole radix tree.  Further, its nodes are a bit on the capacious side
           for what I want - especially given that key serial numbers are randomly
           allocated, thus leaving a lot of empty space in the tree.
           So what I have is an associative array that internally is a radix-tree
           with 16 pointers per node where the index key is constructed from the key
           type pointer and the key description.  This means that an exact lookup by
           type+description is very fast as this tells us how to navigate directly to
           the target key.
           I made the data structure general in lib/assoc_array.c as far as it is
           concerned, its index key is just a sequence of bits that leads to a
           pointer.  It's possible that someone else will be able to make use of it
           also.  FS-Cache might, for example.
         (2) Mark keys as 'trusted' and keyrings as 'trusted only'.
              KEYS: verify a certificate is signed by a 'trusted' key
              KEYS: Make the system 'trusted' keyring viewable by userspace
              KEYS: Add a 'trusted' flag and a 'trusted only' flag
              KEYS: Separate the kernel signature checking keyring from module signing
           These patches allow keys carrying asymmetric public keys to be marked as
           being 'trusted' and allow keyrings to be marked as only permitting the
           addition or linkage of trusted keys.
           Keys loaded from hardware during kernel boot or compiled into the kernel
           during build are marked as being trusted automatically.  New keys can be
           loaded at runtime with add_key().  They are checked against the system
           keyring contents and if their signatures can be validated with keys that
           are already marked trusted, then they are marked trusted also and can
           thus be added into the master keyring.
           Patches from Mimi Zohar make this usable with the IMA keyrings also.
         (3) Remove the date checks on the key used to validate a module signature.
              X.509: Remove certificate date checks
           It's not reasonable to reject a signature just because the key that it was
           generated with is no longer valid datewise - especially if the kernel
           hasn't yet managed to set the system clock when the first module is
           loaded - so just remove those checks.
         (4) Make it simpler to deal with additional X.509 being loaded into the kernel.
              KEYS: Load *.x509 files into kernel keyring
              KEYS: Have make canonicalise the paths of the X.509 certs better to deduplicate
           The builder of the kernel now just places files with the extension ".x509"
           into the kernel source or build trees and they're concatenated by the
           kernel build and stuffed into the appropriate section.
         (5) Add support for userspace kerberos to use keyrings.
              KEYS: Add per-user_namespace registers for persistent per-UID kerberos caches
              KEYS: Implement a big key type that can save to tmpfs
           Fedora went to, by default, storing kerberos tickets and tokens in tmpfs.
           We looked at storing it in keyrings instead as that confers certain
           advantages such as tickets being automatically deleted after a certain
           amount of time and the ability for the kernel to get at these tokens more
           To make this work, two things were needed:
           (a) A way for the tickets to persist beyond the lifetime of all a user's
               sessions so that cron-driven processes can still use them.
               The problem is that a user's session keyrings are deleted when the
               session that spawned them logs out and the user's user keyring is
               deleted when the UID is deleted (typically when the last log out
               happens), so neither of these places is suitable.
               I've added a system keyring into which a 'persistent' keyring is
               created for each UID on request.  Each time a user requests their
               persistent keyring, the expiry time on it is set anew.  If the user
               doesn't ask for it for, say, three days, the keyring is automatically
               expired and garbage collected using the existing gc.  All the kerberos
               tokens it held are then also gc'd.
           (b) A key type that can hold really big tickets (up to 1MB in size).
               The problem is that Active Directory can return huge tickets with lots
               of auxiliary data attached.  We don't, however, want to eat up huge
               tracts of unswappable kernel space for this, so if the ticket is
               greater than a certain size, we create a swappable shmem file and dump
               the contents in there and just live with the fact we then have an
               inode and a dentry overhead.  If the ticket is smaller than that, we
               slap it in a kmalloc()'d buffer"

      Kirill A. Shutemov authored
      I don't know what went wrong, mis-merge or something, but ->pmd_huge_pte
      placed in wrong union within struct page.
      In original patch[1] it's placed to union with ->lru and ->slab, but in
      commit e009bb30 ("mm: implement split page table lock for PMD
      level") it's in union with ->index and ->freelist.
      That union seems also unused for pages with table tables and safe to
      re-use, but it's not what I've tested.
      Let's move it to original place.  It fixes indentation at least.  :)

      ipc,shm: correct error return value in shmctl (SHM_UNLOCK) · 3a72660b
      Jesper Nilsson authored
      Commit 2caacaa8
       ("ipc,shm: shorten critical region for shmctl")
      restructured the ipc shm to shorten critical region, but introduced a
      path where the return value could be -EPERM, even if the operation
      actually was performed.
      Before the commit, the err return value was reset by the return value
      from security_shm_shmctl() after the if (!ns_capable(...)) statement.
      Now, we still exit the if statement with err set to -EPERM, and in the
      case of SHM_UNLOCK, it is not reset at all, and used as the return value
      from shmctl.
      To fix this, we only set err when errors occur, leaving the fallthrough
      case alone.

      Since this is just a read out of bounds it's not that bad, but the
      problem becomes user-visible eg if one tries to use DEBUG_PAGEALLOC and
      DEBUG_RODATA, at least with some enhancements from Hiroshi.  Of course
      the destination array can contain garbage when we read beyond the end of

      Make sure RTC-interrupts are disabled at shutdown.
      As the RTC is generally powered by backup power (VDDBU), its interrupts
      are not disabled on wake-up, user, watchdog or software reset.  This
      could cause troubles on other systems (e.g.  older kernels) if an
      interrupt occurs before a handler has been installed at next boot.
      Let us be well-behaved and disable them on clean shutdowns at least (as
      do the RTT-based rtc-at91sam9 driver).

      mm: hugetlbfs: fix hugetlbfs optimization · 27c73ae7
      Andrea Arcangeli authored
      Commit 7cb2ef56
       ("mm: fix aio performance regression for database
      caused by THP") can cause dereference of a dangling pointer if
      split_huge_page runs during PageHuge() if there are updates to the
      tail_page->private field.
      Also it is repeating compound_head twice for hugetlbfs and it is running
      compound_head+compound_trans_head for THP when a single one is needed in
      both cases.
      The new code within the PageSlab() check doesn't need to verify that the
      THP page size is never bigger than the smallest hugetlbfs page size, to
      avoid memory corruption.
      A longstanding theoretical race condition was found while fixing the
      above (see the change right after the skip_unlock label, that is
      relevant for the compound_lock path too).
      By re-establishing the _mapcount tail refcounting for all compound
      pages, this also fixes the below problem:
