      Pull x86 mm changes from Ingo Molnar:
       "PCID support, 5-level paging support, Secure Memory Encryption support
      
        The main changes in this cycle are support for three new, complex
        hardware features of x86 CPUs:
      
         - Add 5-level paging support, which is a new hardware feature on
           upcoming Intel CPUs allowing up to 128 PB of virtual address space
           and 4 PB of physical RAM space - a 512-fold increase over the old
           limits. (Supercomputers of the future forecasting hurricanes on an
           ever warming planet can certainly make good use of more RAM.)
      
           Many of the necessary changes went upstream in previous cycles,
           v4.14 is the first kernel that can enable 5-level paging.
      
           This feature is activated via CONFIG_X86_5LEVEL=y - disabled by
           default.
      
           (By Kirill A. Shutemov)
      
         - Add 'encrypted memory' support, which is a new hardware feature on
           upcoming AMD CPUs ('Secure Memory Encryption', SME) allowing system
           RAM to be encrypted and decrypted (mostly) transparently by the
           CPU, with a little help from the kernel to transition to/from
           encrypted RAM. Such RAM should be more secure against various
           attacks like RAM access via the memory bus and should make the
           radio signature of memory bus traffic harder to intercept (and
           decrypt) as well.
      
           This feature is activated via CONFIG_AMD_MEM_ENCRYPT=y - disabled
           by default.
      
           (By Tom Lendacky)
      
         - Enable PCID optimized TLB flushing on newer Intel CPUs: PCID is a
           hardware feature that attaches an address space tag to TLB entries
           and thus allows to skip TLB flushing in many cases, even if we
           switch mm's.
      
           (By Andy Lutomirski)
      
        All three of these features were in the works for a long time, and
        it's coincidence of the three independent development paths that they
        are all enabled in v4.14 at once"

      Linus Torvalds authored
      Pull x86 asm updates from Ingo Molnar:
      
       - Introduce the ORC unwinder, which can be enabled via
         CONFIG_ORC_UNWINDER=y.
      
         The ORC unwinder is a lightweight, Linux kernel specific debuginfo
         implementation, which aims to be DWARF done right for unwinding.
         Objtool is used to generate the ORC unwinder tables during build, so
         the data format is flexible and kernel internal: there's no
         dependency on debuginfo created by an external toolchain.
      
         The ORC unwinder is almost two orders of magnitude faster than the
         (out of tree) DWARF unwinder - which is important for perf call graph
         profiling. It is also significantly simpler and is coded defensively:
         there has not been a single ORC related kernel crash so far, even
         with early versions. (knock on wood!)
      
         But the main advantage is that enabling the ORC unwinder allows
         CONFIG_FRAME_POINTERS to be turned off - which speeds up the kernel
         measurably:
      
         With frame pointers disabled, GCC does not have to add frame pointer
         instrumentation code to every function in the kernel. The kernel's
         .text size decreases by about 3.2%, resulting in better cache
         utilization and fewer instructions executed, resulting in a broad
         kernel-wide speedup. Average speedup of system calls should be
         roughly in the 1-3% range - measurements by Mel Gorman [1] have shown
         a speedup of 5-10% for some function execution intense workloads.
      
         The main cost of the unwinder is that the unwinder data has to be
         stored in RAM: the memory cost is 2-4MB of RAM, depending on kernel
         config - which is a modest cost on modern x86 systems.
      
         Given how young the ORC unwinder code is it's not enabled by default
         - but given the performance advantages the plan is to eventually make
         it the default unwinder on x86.
      
         See Documentation/x86/orc-unwinder.txt for more details.
      
       - Remove lguest support: its intended role was that of a temporary
         proof of concept for virtualization, plus its removal will enable the
         reduction (removal) of the paravirt API as well, so Rusty agreed to
         its removal. (Juergen Gross)

      Pull perf updates from Ingo Molnar:
       "Kernel side changes:
      
         - Add branch type profiling/tracing support. (Jin Yao)
      
         - Add the PERF_SAMPLE_PHYS_ADDR ABI to allow the tracing/profiling of
           physical memory addresses, where the PMU supports it. (Kan Liang)
      
         - Export some PMU capability details in the new
           /sys/bus/event_source/devices/cpu/caps/ sysfs directory. (Andi
           Kleen)
      
         - Aux data fixes and updates (Will Deacon)
      
         - kprobes fixes and updates (Masami Hiramatsu)
      
         - AMD uncore PMU driver fixes and updates (Janakarajan Natarajan)
      
        On the tooling side, here's a (limited!) list of highlights - there
        were many other changes that I could not list, see the shortlog and
        git history for details:
      
        UI improvements:
      
         - Implement a visual marker for fused x86 instructions in the
           annotate TUI browser, available now in 'perf report', more work
           needed to have it available as well in 'perf top' (Jin Yao)
      
           Further explanation from one of Jin's patches:
      
                   │   ┌──cmpl   $0x0,argp_program_version_hook
             81.93 │   ├──je     20
                   │   │  lock   cmpxchg %esi,0x38a9a4(%rip)
                   │   │↓ jne    29
                   │   │↓ jmp    43
             11.47 │20:└─→cmpxch %esi,0x38a999(%rip)
      
           That means the cmpl+je is a fused instruction pair and they should
           be considered together.
      
         - Record the branch type and then show statistics and info about in
           callchain entries (Jin Yao)
      
           Example from one of Jin's patches:
      
              # perf record -g -j any,save_type
              # perf report --branch-history --stdio --no-children

                         __random random.c:295 (RET CROSS_2M cycles:9)
      
        namespaces support:
      
         - Add initial support for namespaces, using setns to access files in
           namespaces, grabbing their build-ids, etc. (Krister Johansen)
      
        perf trace enhancements:
      
         - Beautify pkey_{alloc,free,mprotect} arguments in 'perf trace'
           (Arnaldo Carvalho de Melo)
      
         - Add initial 'clone' syscall args beautifier in 'perf trace'
           (Arnaldo Carvalho de Melo)
      
         - Ignore 'fd' and 'offset' args for MAP_ANONYMOUS in 'perf trace'
           (Arnaldo Carvalho de Melo)
      
         - Beautifiers for the 'cmd' arg of several ioctl types, including:
           sound, DRM, KVM, vhost virtio and perf_events. (Arnaldo Carvalho de
           Melo)
      
         - Add PERF_SAMPLE_CALLCHAIN and PERF_RECORD_MMAP[2] to 'perf data'
           CTF conversion, allowing CTF trace visualization tools to show
           callchains and to resolve symbols (Geneviève Bastien)
      
         - Beautify the fcntl syscall, which is an interesting one in the
           sense that infrastructure had to be put in place to change the
           formatters of some arguments according to the value in a previous
           one, i.e. cmd dictates how arg and the syscall return will be
           formatted. (Arnaldo Carvalho de Melo
      
        perf stat enhancements:
      
         - Use group read for event groups in 'perf stat', reducing overhead
           when groups are defined in the event specification, i.e. when using
           {} to enclose a list of events, asking them to be read at the same
           time, e.g.: "perf stat -e '{cycles,instructions}'" (Jiri Olsa)
      
        pipe mode improvements:
      
         - Process tracing data in 'perf annotate' pipe mode (David
           Carrillo-Cisneros)
      
         - Add header record types to pipe-mode, now this command:
      
              $ perf record -o - -e cycles sleep 1 | perf report --stdio --header
      
           Will show the same as in non-pipe mode, i.e. involving a perf.data
           file (David Carrillo-Cisneros)
      
        Vendor specific hardware event support updates/enhancements:
      
         - Update POWER9 vendor events tables (Sukadev Bhattiprolu)
      
         - Add POWER9 PMU events Sukadev (Bhattiprolu)
      
         - Support additional POWER8+ PVR in PMU mapfile (Shriya)
      
         - Add Skylake server uncore JSON vendor events (Andi Kleen)
      
         - Support exporting Intel PT data to sqlite3 with python perf
           scripts, this is in addition to the postgresql support that was
           already there (Adrian Hunter)"

      Linus Torvalds authored
      Pull rdma updates from Doug Ledford:
       "This is a big pull request.
      
        Of note is that I'm sending you the new ioctl API for the rdma
        subsystem. We put it up on linux-api@, but didn't get much response.
        The API is complex, but it solves two different problems in one go:
      
         1) The bi-directional nature of the RDMA file write calls, which
            created the security hole we had to handle (and for which the fix
            is now causing problems for systems in production, we were a bit
            over zealous in the fix and the ability to open a device, then
            fork, then create new queue pairs on the device and use them is
            broken).
      
         2) The bloat caused by different vendors implementing extensions to
            the base verbs API. Each vendor's hardware is slightly different,
            and the hardware might be suitable for one extension but not
            another.
      
            By the time we add generic extensions for all the different ways
            that the different hardware can offload things, the API becomes
            bloated. Things like our completion structs have started to exceed
            a cache line in size because of all the elements needed to support
            this. That in turn shows up heavily in the performance graphs with
            a noticable drop in performance on 100Gigabit links as our
            completion structs go from occupying one cache line to 1+.
      
            This API makes things like the completion structs modular in a
            very similar way to netlink so that your structs can only include
            the items needed for the offloads/features you are actually using
            on a given queue pair. In that way we support everything, but only
            use what we need, and our structs stay smaller.
      
        The ioctl API is better explained by the posting on linux-api@ than I
        can explain it here, so I'll just leave it at that.
      
        The rest of the pull request is typical stuff.

        you.
      
        Outside drm changes:

        place. It adds one export to the radix tree code for new i915 use
        case. There are some minor AGP cleanups (don't see that too often).

      epoll: fix race between ep_poll_callback(POLLFREE) and ep_free()/ep_remove() · 138e4ad6
      Oleg Nesterov authored
      The race was introduced by me in commit 971316f0 ("epoll:
      ep_unregister_pollwait() can use the freed pwq->whead").  I did not
      realize that nothing can protect eventpoll after ep_poll_callback() sets
      ->whead = NULL, only whead->lock can save us from the race with
      ep_free() or ep_remove().
      
      Move ->whead = NULL to the end of ep_poll_callback() and add the
      necessary barriers.
      
      TODO: cleanup the ewake/EPOLLEXCLUSIVE logic, it was confusing even
      before this patch.
      
      Hopefully this explains use-after-free reported by syzcaller:
      
      	BUG: KASAN: use-after-free in debug_spin_lock_before
      	...

      	 ep_poll_callback+0x29f/0xff0 fs/eventpoll.c:1148
      
      this is spin_lock(eventpoll->lock),

      After commit dce4551c ("udp: preserve head state for IP_CMSG_PASSSEC")
      we preserve the secpath for the whole skb lifecycle, but we also
      end up leaking a reference to it.
      
      We must clear the head state on skb reception, if secpath is
      present.
