      rxrpc: Kernel calls get stuck in recvmsg · d7e15835
      David Howells authored
      Calls made through the in-kernel interface can end up getting stuck because
      of a missed variable update in a loop in rxrpc_recvmsg_data().  The problem
      is like this:
      
       (1) A new packet comes in and doesn't cause a notification to be given to
           the client as there's still another packet in the ring - the
           assumption being that if the client will keep drawing off data until
           the ring is empty.
      
       (2) The client is in rxrpc_recvmsg_data(), inside the big while loop that
           iterates through the packets.  This copies the window pointers into
           variables rather than using the information in the call struct
           because:
      
           (a) MSG_PEEK might be in effect;
      
           (b) we need a barrier after reading call->rx_top to pair with the
           	 barrier in the softirq routine that loads the buffer.
      
       (3) The reading of call->rx_top is done outside of the loop, and top is
           never updated whilst we're in the loop.  This means that even through
           there's a new packet available, we don't see it and may return -EFAULT
           to the caller - who will happily return to the scheduler and await the
           next notification.
      
       (4) No further notifications are forthcoming until there's an abort as the
           ring isn't empty.
      
      The fix is to move the read of call->rx_top inside the loop - but it needs
      to be done before the condition is checked.

      net sched actions: decrement module reference count after table flush. · edb9d1bf
      Roman Mashak authored
      When tc actions are loaded as a module and no actions have been installed,
      flushing them would result in actions removed from the memory, but modules
      reference count not being decremented, so that the modules would not be
      unloaded.
      
      Following is example with GACT action:
      
      % sudo modprobe act_gact
      % lsmod
      Module                  Size  Used by
      act_gact               16384  0
      %
      % sudo tc actions ls action gact

      % sudo tc actions flush action gact
      % lsmod

      act_gact               16384  1

      % sudo rmmod act_gact
      rmmod: ERROR: Module act_gact is in use
      ....
      
      After the fix:
      % lsmod
      Module                  Size  Used by
      act_gact               16384  0
      %

      ipv6: check sk sk_type and protocol early in ip_mroute_set/getsockopt · 99253eb7
      Xin Long authored
      Commit 5e1859fb ("ipv4: ipmr: various fixes and cleanups") fixed
      the issue for ipv4 ipmr:
      
        ip_mroute_setsockopt() & ip_mroute_getsockopt() should not
        access/set raw_sk(sk)->ipmr_table before making sure the socket
        is a raw socket, and protocol is IGMP
      
      The same fix should be done for ipv6 ipmr as well.
      
      This patch can fix the panic caused by overwriting the same offset
      as ipmr_table as in raw_sk(sk) when accessing other type's socket
      by ip_mroute_setsockopt().

      sctp: set sin_port for addr param when checking duplicate address · 2e3ce5bc
      Xin Long authored
      Commit b8607805 ("sctp: not copying duplicate addrs to the assoc's
      bind address list") tried to check for duplicate address before copying
      to asoc's bind_addr list from global addr list.
      
      But all the addrs' sin_ports in global addr list are 0 while the addrs'
      sin_ports are bp->port in asoc's bind_addr list. It means even if it's
      a duplicate address, af->cmp_addr will still return 0 as the their
      sin_ports are different.
      
      This patch is to fix it by setting the sin_port for addr param with
      bp->port before comparing the addrs.

      vxlan: don't allow overwrite of config src addr · 1158632b
      Brian Russell authored
      When using IPv6 transport and a default dst, a pointer to the configured
      source address is passed into the route lookup. If no source address is
      configured, then the value is overwritten.
      
      IPv6 route lookup ignores egress ifindex match if the source address is set,
      so if egress ifindex match is desired, the source address must be passed
      as any. The overwrite breaks this for subsequent lookups.
      
      Avoid this by copying the configured address to an existing stack variable
      and pass a pointer to that instead.

      rxrpc: Fix an assertion in rxrpc_read() · 774521f3
      Marc Dionne authored
      In the rxrpc_read() function, which allows a user to read the contents of a
      key, we miscalculate the expected length of an encoded rxkad token by not
      taking into account the key length.  However, the data is stored later
      anyway with an ENCODE_DATA() call - and an assertion failure then ensues
      when the lengths are checked at the end.
      
      Fix this by including the key length in the token size estimation.
      
      The following assertion is produced:
      
      Assertion failed - 384(0x180) == 380(0x17c) is false

      sctp: deny peeloff operation on asocs with threads sleeping on it · dfcb9f4f
      Marcelo Ricardo Leitner authored
      commit 2dcab598 ("sctp: avoid BUG_ON on sctp_wait_for_sndbuf")
      attempted to avoid a BUG_ON call when the association being used for a
      sendmsg() is blocked waiting for more sndbuf and another thread did a
      peeloff operation on such asoc, moving it to another socket.
      
      As Ben Hutchings noticed, then in such case it would return without
      locking back the socket and would cause two unlocks in a row.
      
      Further analysis also revealed that it could allow a double free if the
      application managed to peeloff the asoc that is created during the
      sendmsg call, because then sctp_sendmsg() would try to free the asoc
      that was created only for that call.
      
      This patch takes another approach. It will deny the peeloff operation
      if there is a thread sleeping on the asoc, so this situation doesn't
      exist anymore. This avoids the issues described above and also honors
      the syscalls that are already being handled (it can be multiple sendmsg
      calls).
      
      Joint work with Xin Long.

      Linus Torvalds authored
      Pull namespace updates from Eric Biederman:
       "There is a lot here. A lot of these changes result in subtle user
        visible differences in kernel behavior. I don't expect anything will
        care but I will revert/fix things immediately if any regressions show
        up.
      
        From Seth Forshee there is a continuation of the work to make the vfs
        ready for unpriviled mounts. We had thought the previous changes
        prevented the creation of files outside of s_user_ns of a filesystem,
        but it turns we missed the O_CREAT path. Ooops.
      
        Pavel Tikhomirov and Oleg Nesterov worked together to fix a long
        standing bug in the implemenation of PR_SET_CHILD_SUBREAPER where only
        children that are forked after the prctl are considered and not
        children forked before the prctl. The only known user of this prctl
        systemd forks all children after the prctl. So no userspace
        regressions will occur. Holding earlier forked children to the same
        rules as later forked children creates a semantic that is sane enough
        to allow checkpoing of processes that use this feature.
      
        There is a long delayed change by Nikolay Borisov to limit inotify
        instances inside a user namespace.
      
        Michael Kerrisk extends the API for files used to maniuplate
        namespaces with two new trivial ioctls to allow discovery of the
        hierachy and properties of namespaces.
      
        Konstantin Khlebnikov with the help of Al Viro adds code that when a
        network namespace exits purges it's sysctl entries from the dcache. As
        in some circumstances this could use a lot of memory.
      
        Vivek Goyal fixed a bug with stacked filesystems where the permissions
        on the wrong inode were being checked.
      
        I continue previous work on ptracing across exec. Allowing a file to
        be setuid across exec while being ptraced if the tracer has enough
        credentials in the user namespace, and if the process has CAP_SETUID
        in it's own namespace. Proc files for setuid or otherwise undumpable
        executables are now owned by the root in the user namespace of their
        mm. Allowing debugging of setuid applications in containers to work
        better.
      
        A bug I introduced with permission checking and automount is now
        fixed. The big change is to mark the mounts that the kernel initiates
        as a result of an automount. This allows the permission checks in sget
        to be safely suppressed for this kind of mount. As the permission
        check happened when the original filesystem was mounted.
      
        Finally a special case in the mount namespace is removed preventing
        unbounded chains in the mount hash table, and making the semantics
        simpler which benefits CRIU.
      
        The vfs fix along with related work in ima and evm I believe makes us
        ready to finish developing and merge fully unprivileged mounts of the
        fuse filesystem. The cleanups of the mount namespace makes discussing
        how to fix the worst case complexity of umount. The stacked filesystem
        fixes pave the way for adding multiple mappings for the filesystem
        uids so that efficient and safer containers can be implemented"

      Pull drm updates from Dave Airlie:
       "This is the main drm pull request for v4.11.
      
        Nothing too major, the tinydrm and mmu-less support should make
        writing smaller drivers easier for some of the simpler platforms, and
        there are a bunch of documentation updates.
      
        Intel grew displayport MST audio support which is hopefully useful to
        people, and FBC is on by default for GEN9+ (so people know where to
        look for regressions). AMDGPU has a lot of fixes that would like new
        firmware files installed for some GPUs.
      
        Other than that it's pretty scattered all over.
      
        I may have a follow up pull request as I know BenH has a bunch of AST
        rework and fixes and I'd like to get those in once they've been tested
        by AST, and I've got at least one pull request I'm just trying to get
        the author to fix up.

       "In the SoC branch we normally collect classic arch/arm/mach-*
        contents, i.e. C code changes for SoC platforms. This release cycle
        the diffstat is quite nice, in that we're removing 3x the amount of
        code that's being added.
      
        The main reason for this is that there's a removal of camera drivers
        for Freescale i.MX chips (driver was removed so the device
        registration isn't needed any more). There's also removal of display
        initialization code for OMAP that is no longer needed.
      
        The rest are mostly minor tweaks and cleanups; constification on
        Samsung platforms, cleanup of ux500 platform data, purge of other
        unused platform data/device seutp on i.MX and other good stuff.
