      Pull overflow updates from Kees Cook:
       "This adds the new overflow checking helpers and adds them to the
        2-factor argument allocators. And this adds the saturating size
        helpers and does a treewide replacement for the struct_size() usage.
        Additionally this adds the overflow testing modules to make sure
        everything works.
      
        I'm still working on the treewide replacements for allocators with
        "simple" multiplied arguments:
      
           *alloc(a * b, ...) -> *alloc_array(a, b, ...)
      
        and
      
           *zalloc(a * b, ...) -> *calloc(a, b, ...)
      
        as well as the more complex cases, but that's separable from this
        portion of the series. I expect to have the rest sent before -rc1
        closes; there are a lot of messy cases to clean up.
      
        Summary:
      
         - Introduce arithmetic overflow test helper functions (Rasmus)
      
         - Use overflow helpers in 2-factor allocators (Kees, Rasmus)
      
         - Introduce overflow test module (Rasmus, Kees)
      
         - Introduce saturating size helper functions (Matthew, Kees)
      
         - Treewide use of struct_size() for allocators (Kees)"

      Linus Torvalds authored
      Pull audit updates from Paul Moore:
       "Another reasonable chunk of audit changes for v4.18, thirteen patches
        in total.
      
        The thirteen patches can mostly be broken down into one of four
        categories: general bug fixes, accessor functions for audit state
        stored in the task_struct, negative filter matches on executable
        names, and extending the (relatively) new seccomp logging knobs to the
        audit subsystem.
      
        The main driver for the accessor functions from Richard are the
        changes we're working on to associate audit events with containers,
        but I think they have some standalone value too so I figured it would
        be good to get them in now.
      
        The seccomp/audit patches from Tyler apply the seccomp logging
        improvements from a few releases ago to audit's seccomp logging;
        starting with this patchset the changes in
        /proc/sys/kernel/seccomp/actions_logged should apply to both the
        standard kernel logging and audit.
      
        As usual, everything passes the audit-testsuite and it happens to
        merge cleanly with your tree"

        also came in from Paul   - Linus ]

      Pull security system updates from James Morris:
      
       - incorporate new socketpair() hook into LSM and wire up the SELinux
         and Smack modules. From David Herrmann:
      
           "The idea is to allow SO_PEERSEC to be called on AF_UNIX sockets
            created via socketpair(2), and return the same information as if
            you emulated socketpair(2) via a temporary listener socket.
      
            Right now SO_PEERSEC will return the unlabeled credentials for a
            socketpair, rather than the actual credentials of the creating
            process."
      
       - remove the unused security_settime LSM hook (Sargun Dhillon).

       "It's been a busy release for the IPMI driver. Some notable changes:
      
         - A user was running into timeout issues doing maintenance commands
           over the IPMB network behind an IPMI controller.
      
           Extend the maintenance mode concept to messages over IPMB and allow
           the timeouts to be tuned.
      
         - Lots of cleanup, style fixing, some bugfixes, and such.
      
         - At least one user was having trouble with the way the IPMI driver
           would lock the i2c driver module it used.
      
           The IPMI driver was not designed for hotplug. However, hotplug is a
           reality now, so the IPMI driver was modified to support hotplug.

         Alexandre Belloni.
      
       - Several minor spelling and bug fixes.
      
       - New cgroup tests from Roman Gushchin and Mike Rapoport.
      
       - Kselftest framework changes to handle and report skipped tests
         correctly.
      
         Prior to these changes, framework treated all non-zero return codes
         from tests as failures. When tests are skipped with non-zero return
         code, due to unmet dependencies and/or unsupported configuration,
         reporting them as failed lead to false negatives on the tests that
         couldn't be run.
      
       - Fixes to test Makefiles to remove unnecessary RUN_TESTS and
         EMIT_TESTS overrides and use common defines from lib.mk.

       "Kconfig now supports new functionality to perform textual

        language.
      
        Some built-in functions such as 'shell' are provided. Variables and
        user-defined functions are also supported so that 'cc-option',
        'ld-option', etc. are implemented as macros.
      
        Summary:
      
         - refactor package checks for building {m,n,q,g}conf
      
         - remove unused/unmaintained localization support

      treewide: Use struct_size() for kmalloc()-family · acafe7e3
      Kees Cook authored
      One of the more common cases of allocation size calculations is finding
      the size of a structure that has a zero-sized array at the end, along
      with memory for some number of elements for that array. For example:
      
      struct foo {
          int stuff;
          void *entry[];
      };
      
      instance = kmalloc(sizeof(struct foo) + sizeof(void *) * count, GFP_KERNEL);
      
      Instead of leaving these open-coded and prone to type mistakes, we can
      now use the new struct_size() helper:
      
      instance = kmalloc(struct_size(instance, entry, count), GFP_KERNEL);
      
      This patch makes the changes for kmalloc()-family (and kvmalloc()-family)
      uses. It was done via automatic conversion with manual review for the
      "CHECKME" non-standard cases noted below, using the following Coccinelle
      script:
      
      // pkey_cache = kmalloc(sizeof *pkey_cache + tprops->pkey_tbl_len *

      strparser: Add __strp_unpause and use it in ktls. · 7170e604
      Doron Roberts-Kedes authored
      strp_unpause queues strp_work in order to parse any messages that
      arrived while the strparser was paused. However, the process invoking
      strp_unpause could eagerly parse a buffered message itself if it held
      the sock lock.
      
      __strp_unpause is an alternative to strp_pause that avoids the scheduling
      overhead that results when a receiving thread unpauses the strparser
      and waits for the next message to be delivered by the workqueue thread.
      
      This patch more than doubled the IOPS achieved in a benchmark of NBD
      traffic encrypted using ktls.

      rxrpc: Fix terminal retransmission connection ID to include the channel · fb1967a6
      David Howells authored
      When retransmitting the final ACK or ABORT packet for a call, the cid field
      in the packet header is set to the connection's cid, but this is incorrect
      as it also needs to include the channel number on that connection that the
      call was made on.
      
      Fix this by OR'ing in the channel number.
      
      Note that this fixes the bug that:
      
      	commit 1a025028
      	rxrpc: Fix handling of call quietly cancelled out on server
      
      works around.  I'm not intending to revert that as it will help protect

      net: dsa: b53: Fix for brcm tag issue in Cygnus SoC · 5040cc99
      Arun Parameswaran authored
      In the Broadcom Cygnus SoC, the brcm tag needs to be inserted
      in between the mac address and the ether type (should use
      'DSA_PROTO_TAG_BRCM') for the packets sent to the internal
      b53 switch.
      
      Since the Cygnus was added with the BCM58XX device id and the
      BCM58XX uses 'DSA_PROTO_TAG_BRCM_PREPEND', the data path is
      broken, due to the incorrect brcm tag location.
      
      Add a new b53 device id (BCM583XX) for Cygnus family to fix the
      issue. Add the new device id to the BCM58XX family as Cygnus
      is similar to the BCM58XX in most other functionalities.
      
      Fixes: 11606039 ("net: dsa: b53: Support prepended Broadcom tags")

      enic: fix UDP rss bits · 4016a7f1
      Govindarajulu Varadarajan authored
      In commit 48398b6e ("enic: set UDP rss flag") driver needed to set a
      single bit to enable UDP rss. This is changed to two bit. One for UDP
      IPv4 and other bit for UDP IPv6. The hardware which supports this is not
      released yet. When released, driver should set 2 bit to enable UDP rss for
      both IPv4 and IPv6.
      
      Also add spinlock around vnic_dev_capable_rss_hash_type().

      Pull cgroup updates from Tejun Heo:
      
       - For cpustat, cgroup has a percpu hierarchical stat mechanism which
         propagates up the hierarchy lazily.
      
         This contains commits to factor out and generalize the mechanism so
         that it can be used for other cgroup stats too.
      
         The original intention was to update memcg stats to use it but memcg
         went for a different approach, so still the only user is cpustat. The
         factoring out and generalization still make sense and it's likely
         that this can be used for other purposes in the future.
      
       - cgroup uses kernfs_notify() (which uses fsnotify()) to inform user
         space of certain events. A rate limiting mechanism is added.
      
       - Other misc changes.

       - libata has always been limiting the maximum queue depth to 31, with
