      Linus Torvalds authored
      Pull pidfd fix from Christian Brauner:
       "This fixes a problem reported by lockdep when installing a pidfd via
        fd_install() with siglock and the tasklisk write lock held in
        copy_process() when calling clone()/clone3() with CLONE_PIDFD.
      
        Originally a pidfd was created prior to holding any of these locks but
        this required a call to ksys_close(). So quite some time ago in
        6fd2fe49 ("copy_process(): don't use ksys_close() on cleanups") we
        switched to a get_unused_fd_flags() + fd_install() model.
      
        As part of that we moved fd_install() as late as possible. This was
        done for two main reasons. First, because we needed to ensure that we
        call fd_install() past the point of no return as once that's called
        the fd is live in the task's file table. Second, because we tried to
        ensure that the fd is visible in /proc/<pid>/fd/<pidfd> right when the
        task is visible.
      
        This fix moves the fd_install() to an even later point which means
        that a task will be visible in proc while the pidfd isn't yet under
        /proc/<pid>/fd/<pidfd>.
      
        While this is a user visible change it's very unlikely that this will
        have any impact. Nobody should be relying on that and if they do we
        need to come up with something better but again, it's doubtful this is
        relevant"

      Pull ucounts fixes from Eric Biederman:
       "Michal Koutný recently found some bugs in the enforcement of
        RLIMIT_NPROC in the recent ucount rlimit implementation.
      
        In this set of patches I have developed a very conservative approach
        changing only what is necessary to fix the bugs that I can see
        clearly. Cleanups and anything that is making the code more consistent
        can follow after we have the code working as it has historically.
      
        The problem is not so much inconsistencies (although those exist) but
        that it is very difficult to figure out what the code should be doing
        in the case of RLIMIT_NPROC.
      
        All other rlimits are only enforced where the resource is acquired
        (allocated). RLIMIT_NPROC by necessity needs to be enforced in an
        additional location, and our current implementation stumbled it's way
        into that implementation"

      Input: psmouse - set up dependency between PS/2 and SMBus companions · 7b1f781f
      Dmitry Torokhov authored
      When we switch from emulated PS/2 to native (RMI4 or Elan) protocols, we
      create SMBus companion devices that are attached to I2C/SMBus controllers.
      However, when suspending and resuming, we also need to make sure that we
      take into account the PS/2 device they are associated with, so that PS/2
      device is suspended after the companion and resumed before it, otherwise
      companions will not work properly. Before I2C devices were marked for
      asynchronous suspend/resume, this ordering happened naturally, but now we
      need to enforce it by establishing device links, with PS/2 devices being
      suppliers and SMBus companions being consumers.
      
      Fixes: 172d9319 ("i2c: enable async suspend/resume on i2c client devices")

      bonding: force carrier update when releasing slave · a6ab75ce
      Zhang Changzhong authored
      In __bond_release_one(), bond_set_carrier() is only called when bond
      device has no slave. Therefore, if we remove the up slave from a master
      with two slaves and keep the down slave, the master will remain up.
      
      Fix this by moving bond_set_carrier() out of if (!bond_has_slaves(bond))
      statement.
      
      Reproducer:
      $ insmod bonding.ko mode=0 miimon=100 max_bonds=2
      $ ifconfig bond0 up
      $ ifenslave bond0 eth0 eth1
      $ ifconfig eth0 down
      $ ifenslave -d bond0 eth1
      $ cat /proc/net/bonding/bond0

      Check for a hwaccel VLAN tag on rx and use it if present.  Otherwise,
      use __skb_vlan_pop() like the other tag parsers do.  This fixes the case
      where the VLAN tag has already been consumed by the master.

      mm: don't try to NUMA-migrate COW pages that have other uses · 80d47f5d
      Linus Torvalds authored
      Oded Gabbay reports that enabling NUMA balancing causes corruption with
      his Gaudi accelerator test load:
      
       "All the details are in the bug, but the bottom line is that somehow,
        this patch causes corruption when the numa balancing feature is
        enabled AND we don't use process affinity AND we use GUP to pin pages
        so our accelerator can DMA to/from system memory.
      
        Either disabling numa balancing, using process affinity to bind to
        specific numa-node or reverting this patch causes the bug to
        disappear"
      
      and Oded bisected the issue to commit 09854ba9 ("mm: do_wp_page()
      simplification").
      
      Now, the NUMA balancing shouldn't actually be changing the writability
      of a page, and as such shouldn't matter for COW.  But it appears it
      does.  Suspicious.
      
      However, regardless of that, the condition for enabling NUMA faults in
      change_pte_range() is nonsensical.  It uses "page_mapcount(page)" to
      decide if a COW page should be NUMA-protected or not, and that makes
      absolutely no sense.
      
      The number of mappings a page has is irrelevant: not only does GUP get a
      reference to a page as in Oded's case, but the other mappings migth be
      paged out and the only reference to them would be in the page count.
      
      Since we should never try to NUMA-balance a page that we can't move
      anyway due to other references, just fix the code to use 'page_count()'.
      Oded confirms that that fixes his issue.
      
      Now, this does imply that something in NUMA balancing ends up changing
      page protections (other than the obvious one of making the page
      inaccessible to get the NUMA faulting information).  Otherwise the COW
      simplification wouldn't matter - since doing the GUP on the page would
      make sure it's writable.
      
      The cause of that permission change would be good to figure out too,
      since it clearly results in spurious COW events - but fixing the
      nonsensical test that just happened to work before is obviously the
      CorrectThing(tm) to do regardless.

      vsock: remove vsock from connected table when connect is interrupted by a signal · b9208492
      Seth Forshee authored
      vsock_connect() expects that the socket could already be in the
      TCP_ESTABLISHED state when the connecting task wakes up with a signal
      pending. If this happens the socket will be in the connected table, and
      it is not removed when the socket state is reset. In this situation it's
      common for the process to retry connect(), and if the connection is
      successful the socket will be added to the connected table a second
      time, corrupting the list.
      
      Prevent this by calling vsock_remove_connected() if a signal is received
      while waiting for a connection. This is harmless if the socket is not in
      the connected table, and if it is in the table then removing it will
      prevent list corruption from a double add.
      
      Note for backporting: this patch requires d5afa82c ("vsock: correct
      removal of socket from the list"), which is in all current stable trees
      except 4.9.y.

      ucounts: Handle wrapping in is_ucounts_overlimit · 0cbae9e2
      Eric W. Biederman authored
      While examining is_ucounts_overlimit and reading the various messages
      I realized that is_ucounts_overlimit fails to deal with counts that
      may have wrapped.
      
      Being wrapped should be a transitory state for counts and they should
      never be wrapped for long, but it can happen so handle it.
