       1) Fix memory leaks and other issues in mwifiex driver, from Amitkumar
          Karwar.
      
       2) skb_segment() can choke on packets using frag lists, fix from
          Herbert Xu with help from Eric Dumazet and others.
      
       3) IPv4 output cached route instantiation properly handles races
          involving two threads trying to install the same route, but we
          forgot to propagate this logic to input routes as well.  Fix from
          Alexei Starovoitov.
      
       4) Put protections in place to make sure that recvmsg() paths never
          accidently copy uninitialized memory back into userspace and also
          make sure that we never try to use more that sockaddr_storage for
          building the on-kernel-stack copy of a sockaddr.  Fixes from Hannes
          Frederic Sowa.
      
       5) R8152 driver transmit flow bug fixes from Hayes Wang.
      
       6) Fix some minor fallouts from genetlink changes, from Johannes Berg
          and Michael Opdenacker.
      
       7) AF_PACKET sendmsg path can race with netdevice unregister notifier,
          fix by using RCU to make sure the network device doesn't go away
          from under us.  Fix from Daniel Borkmann.

      David Henningsson authored
      current_headset_type should be of the HEADSET_TYPE enum, not the
      HEADSET_MODE enum. Since ALC_HEADSET_TYPE_UNKNOWN and ALC_HEADSET_MODE_UNKNOWN
      are both 0, this patch is just janitorial.

      ALSA: hda - Provide missing pin configs for VAIO with ALC260 · d08c5ef2
      Takashi Iwai authored
      Some models (or maybe depending on BIOS version) of Sony VAIO with
      ALC260 give no proper pin configurations as default, resulting in the
      non-working speaker, etc.  Just provide the whole pin configurations
      via a fixup.

       "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
           easily.
      
           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"

      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.  :)

      There are two code paths how page with pmd page table can be freed:
      pmd_free() and pmd_free_tlb().
      
      I've missed the second one and didn't add page table destructor call
      there.  It leads to leak of page->ptl for pmd page tables, if
      dynamically allocated page->ptl is in use.

      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.

      Use ARRAY_SIZE instead of sizeof to get proper max for label length.
      
      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
      source array so that would be another user-visible problem.

      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).

      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:
      
        echo 0 >/sys/kernel/mm/hugepages/hugepages-2048kB/nr_hugepages

      ipc,shm: fix shm_file deletion races · a399b29d
      Greg Thelen authored
      When IPC_RMID races with other shm operations there's potential for
      use-after-free of the shm object's associated file (shm_file).
      
      Here's the race before this patch:
      
        TASK 1                     TASK 2
        ------                     ------
        shm_rmid()
          ipc_lock_object()
                                   shmctl()
                                   shp = shm_obtain_object_check()
      
          shm_destroy()
            shum_unlock()
            fput(shp->shm_file)
                                   ipc_lock_object()
                                   shmem_lock(shp->shm_file)
                                   <OOPS>
      
      The oops is caused because shm_destroy() calls fput() after dropping the
      ipc_lock.  fput() clears the file's f_inode, f_path.dentry, and
      f_path.mnt, which causes various NULL pointer references in task 2.  I
      reliably see the oops in task 2 if with shmlock, shmu
      
      This patch fixes the races by:
      1) set shm_file=NULL in shm_destroy() while holding ipc_object_lock().
      2) modify at risk operations to check shm_file while holding
         ipc_object_lock().
      
      Example workloads, which each trigger oops...
      
      Workload 1:
        while true; do
          id=$(shmget 1 4096)
          shm_rmid $id &
          shmlock $id &
          wait
        done
      
        The oops stack shows accessing NULL f_inode due to racing fput:
          _raw_spin_lock
          shmem_lock
          SyS_shmctl
      
      Workload 2:
        while true; do
          id=$(shmget 1 4096)
          shmat $id 4096 &
          shm_rmid $id &
          wait
        done
      
        The oops stack is similar to workload 1 due to NULL f_inode:
          touch_atime
          shmem_mmap
          shm_mmap
          mmap_region
          do_mmap_pgoff
          do_shmat
          SyS_shmat
      
      Workload 3:
        while true; do
          id=$(shmget 1 4096)
          shmlock $id
          shm_rmid $id &
          shmunlock $id &
          wait
        done
      
        The oops stack shows second fput tripping on an NULL f_inode.  The
        first fput() completed via from shm_destroy(), but a racing thread did
        a get_file() and queued this fput():
          locks_remove_flock
          __fput
          ____fput
          task_work_run
          do_notify_resume
          int_signal
      
      Fixes: c2c737a0 ("ipc,shm: shorten critical region for shmat")
      Fixes: 2caacaa8 ("ipc,shm: shorten critical region for shmctl")

      mm: thp: give transparent hugepage code a separate copy_page · 30b0a105
      Dave Hansen authored
      Right now, the migration code in migrate_page_copy() uses copy_huge_page()
      for hugetlbfs and thp pages:
      
             if (PageHuge(page) || PageTransHuge(page))
                      copy_huge_page(newpage, page);
      
      So, yay for code reuse.  But:
      
        void copy_huge_page(struct page *dst, struct page *src)
        {
              struct hstate *h = page_hstate(src);
      
      and a non-hugetlbfs page has no page_hstate().  This works 99% of the
      time because page_hstate() determines the hstate from the page order
      alone.  Since the page order of a THP page matches the default hugetlbfs
      page order, it works.
      
      But, if you change the default huge page size on the boot command-line
      (say default_hugepagesz=1G), then we might not even *have* a 2MB hstate
      so page_hstate() returns null and copy_huge_page() oopses pretty fast
      since copy_huge_page() dereferences the hstate:
      
        void copy_huge_page(struct page *dst, struct page *src)
        {
              struct hstate *h = page_hstate(src);
              if (unlikely(pages_per_huge_page(h) > MAX_ORDER_NR_PAGES)) {
        ...
      
      Mel noticed that the migration code is really the only user of these
      functions.  This moves all the copy code over to migrate.c and makes
      copy_huge_page() work for THP by checking for it explicitly.
      
      I believe the bug was introduced in commit b32967ff ("mm: numa: Add
      THP migration for the NUMA working set scanning fault case")

      configfs: fix race between dentry put and lookup · 76ae281f
      Junxiao Bi authored
      A race window in configfs, it starts from one dentry is UNHASHED and end
      before configfs_d_iput is called.  In this window, if a lookup happen,
      since the original dentry was UNHASHED, so a new dentry will be
      allocated, and then in configfs_attach_attr(), sd->s_dentry will be
      updated to the new dentry.  Then in configfs_d_iput(),
      BUG_ON(sd->s_dentry != dentry) will be triggered and system panic.
      
      sys_open:                     sys_close:
       ...                           fput
                                      dput
                                       dentry_kill
                                        __d_drop <--- dentry unhashed here,
                                                 but sd->dentry still point
                                                 to this dentry.
      
       lookup_real
        configfs_lookup
         configfs_attach_attr---> update sd->s_dentry
                                  to new allocated dentry here.
      
                                         d_kill
                                           configfs_d_iput <--- BUG_ON(sd->s_dentry != dentry)
                                                           triggered here.
      
      To fix it, change configfs_d_iput to not update sd->s_dentry if
      sd->s_count > 2, that means there are another dentry is using the sd
      beside the one that is going to be put.  Use configfs_dirent_lock in
      configfs_attach_attr to sync with configfs_d_iput.
      
      With the following steps, you can reproduce the bug.
      
      1. enable ocfs2, this will mount configfs at /sys/kernel/config and
         fill configure in it.
      
      2. run the following script.
      	while [ 1 ]; do cat /sys/kernel/config/cluster/$your_cluster_name/idle_timeout_ms > /dev/null; done &
      	while [ 1 ]; do cat /sys/kernel/config/cluster/$your_cluster_name/idle_timeout_ms > /dev/null; done &
