      perf record: Add an option to force per-cpu mmaps · 539e6bb7
      Adrian Hunter authored
      By default, when tasks are specified (i.e. -p, -t or -u options)
      per-thread mmaps are created.
      
      Add an option to override that and force per-cpu mmaps.
      
      Further comments by peterz:
      
      So this option allows -t/-p/-u to create one buffer per cpu and attach
      all the various thread/process/user tasks' their counters to that one
      buffer?
      
      As opposed to the current state where each such counter would have its
      own buffer.

      perf probe: Add '--demangle'/'--no-demangle' · 35e17b24
      Azat Khuzhin authored
      You can't pass demangled name into "perf probe", because of special chars:
      ./perf probe -f -x /tmp/a.out 'foo(int)'
      Semantic error :There is non-digit char in line number.
      
      And you can't even pass without demangling (because it search symbol in
      DSO with demangle=true):
      ./perf probe -f -x /tmp/a.out _Z3fooi
      no symbols found in /tmp/a.out, maybe install a debug package?
      
      However:
      nm /tmp/a.out | grep foo
      000000000040056d T _Z3fooi
      
      After this patch, using the next command:
      ./perf probe -f --no-demangle -x /tmp/a.out _Z3fooi
      
      probe will be successfully added.

      perf symbols: Limit max callchain using max_stack on DWARF unwinding too · 37676af1
      Arnaldo Carvalho de Melo authored
      It was affecting only frame-pointer (fp) based callchain processing.
      
      Usage example:
      
        perf top --call-graph dwarf,1024 --max-stack 2
      
      Works for any tool that does callchain resolving and provides a
      --max-stack option.

      perf tools: Synthesize anon MMAP records again · 9d4ecc88
      Don Zickus authored
      When introducing the PERF_RECORD_MMAP2 in:
      
      5c5e854b perf tools: Add attr->mmap2 support
      
      A check for the number of entries parsed by sscanf was introduced that
      assumed all of the 8 fields needed to be correctly parsed so that
      particular /proc/pid/maps line would be considered synthesizable.
      
      That broke anon records synthesizing, as it doesn't have the 'execname'
      field.
      
      Fix it by keeping the sscanf return check, changing it to not require
      that the 'execname' variable be parsed, so that the preexisting logic
      can kick in and set it to '//anon'.
      
      This should get things like JIT profiling working again.

      tools/perf/build: Fix feature-libunwind-debug-frame handling · e310718d
      Ingo Molnar authored
      Set feature-libunwind-debug-frame. We don't want it in
      CORE_FEATURE_TESTS because it's not the generic case, but we
      need to set it in the !feature-libunwind case.
      
      Also, because x86 distributions typically don't have
      dwarf_find_debug_frame() unwinding method:
      
        test-libunwind-debug-frame.c:(.text+0x31): undefined reference to `_Ux86_64_dwarf_find_debug_frame'
      
      Restrict this new API to ARM for the time being.
      
      With this patch test-all.c works again, so repeat perf builds
      are  fast again:

      tools/perf/build: Fix timerfd feature check · bb4c5500
      Ingo Molnar authored
      'feature_timerfd' is checked all the time and calculated explicitly,
      in a serial fashion. Add it to CORE_FEATURE_TESTS which causes it to
      be built in parallel, using the newfangled parallel build autodetection
      code.
      
      This shaves 137 msecs off the perf build time on my system, which

         - dm crypt support for activating legacy CBC TrueCrypt containers
           (useful for forensics of these old TCRYPT containers)
         - reduced dm-cache memory requirements for each block in the cache
         - basic support for shrinking a dm-cache's cache (fast) device
         - most notably, dm-cache support for managing cache coherency when
           deploying dm-cache with sophisticated origin volumes (that support
           hardware snapshots and/or clustering): these changes come in the
           form of a new passthrough operation mode and a cache block

       - Unify some compile-time differences so that we have fewer uses of
         #ifdef CONFIG_OF in atmel_nand
       - Other general cleanups (removing unused functions, options,
         variables, fields; use correct interfaces)

         dimensions via ONFI
       - Miscellaneous driver fixes (SPI NOR flash; BCM47xx NAND flash; etc.)
       - Improve differentiation between SLC and MLC NAND -- this clarifies an
         ABI issue regarding the MTD "type" (in sysfs and in the MEMGETINFO
         ioctl), where the MTD_MLCNANDFLASH type was present but
         inconsistently used
       - Extend GPMI NAND to support multi-chip-select NAND for some platforms
       - Many improvements to the OMAP2/3 NAND driver, including an expanded
         DT binding to bring us closer to mainline support for some OMAP
         systems
       - Fix a deadlock in the error path of the Atmel NAND driver probe
       - Correct the error codes from MTD mmap() to conform to POSIX and the
         Linux Programmer's Manual.  This is an acknowledged change in the MTD
         ABI, but I can't imagine somebody relying on the non-standard -ENOSYS
         error code specifically.  Am I just being unimaginative? :)
       - Fix a few important GPMI NAND bugs (one regression from 3.12 and one

      Pull block IO core updates from Jens Axboe:

         - The new blk-mq request interface.
      
           This is a new and more scalable queueing model that marries the
           best part of the request based interface we currently have (which
           is fully featured, but scales poorly) and the bio based "interface"
           which the new drivers for high IOPS devices end up using because
           it's much faster than the request based one.
      
           The bio interface has no block layer support, since it taps into
           the stack much earlier.  This means that drivers end up having to
           implement a lot of functionality on their own, like tagging,
           timeout handling, requeue, etc.  The blk-mq interface provides all
           these.  Some drivers even provide a switch to select bio or rq and
           has code to handle both, since things like merging only works in
           the rq model and hence is faster for some workloads.  This is a
           huge mess.  Conversion of these drivers nets us a substantial code
           reduction.  Initial results on converting SCSI to this model even
           shows an 8x improvement on single queue devices.  So while the
           model was intended to work on the newer multiqueue devices, it has
           substantial improvements for "classic" hardware as well.  This code
           has gone through extensive testing and development, it's now ready
           to go.  A pull request is coming to convert virtio-blk to this
           model will be will be coming as well, with more drivers scheduled
           for 3.14 conversion.

        A heads-up that I had to rebase this branch.  Initially the immutable
        bio_vecs had been queued up for inclusion, but a week later, it became
        clear that it wasn't fully cooked yet.  So the decision was made to
        pull this out and postpone it until 3.14.  It was a straight forward
        rebase, just pruning out the immutable series and the later fixes of
        problems with it.  The rest of the patches applied directly and no
        further changes were made"

      Pull ARM updates from Russell King:
       "Included in this series are:
      
         1. BE8 (modern big endian) changes for ARM from Ben Dooks
         2. big.Little support from Nicolas Pitre and Dave Martin
         3. support for LPAE systems with all system memory above 4GB
         4. Perf updates from Will Deacon
         5. Additional prefetching and other performance improvements from Will.
         6. Neon-optimised AES implementation fro Ard.
         7. A number of smaller fixes scattered around the place.
      
        There is a rather horrid merge conflict in tools/perf - I was never
        notified of the conflict because it originally occurred between Will's
        tree and other stuff.  Consequently I have a resolution which Will
        forwarded me, which I'll forward on immediately after sending this
        mail.
      
        The other notable thing is I'm expecting some build breakage in the
        crypto stuff on ARM only with Ard's AES patches.  These were merged
        into a stable git branch which others had already pulled, so there's
        little I can do about this.  The problem is caused because these
        patches have a dependency on some code in the crypto git tree - I
        tried requesting a branch I can pull to resolve these, and all I got
        each time from the crypto people was "we'll revert our patches then"
        which would only make things worse since I still don't have the
        dependent patches.  I've no idea what's going on there or how to
        resolve that, and since I can't split these patches from the rest of
        this pull request, I'm rather stuck with pushing this as-is or
        reverting Ard's patches.
      
        Since it should "come out in the wash" I've left them in - the only
        build problems they seem to cause at the moment are with randconfigs,
        and since it's a new feature anyway.  However, if by -rc1 the
        dependencies aren't in, I think it'd be best to revert Ard's patches"
      
      I resolved the perf conflict roughly as per the patch sent by Russell,
      but there may be some differences.  Any errors are likely mine.  Let's
      see how the crypto issues work out..

      Linus Torvalds authored
      Pull DMA mask updates from Russell King:
       "This series cleans up the handling of DMA masks in a lot of drivers,
        fixing some bugs as we go.
      
        Some of the more serious errors include:
         - drivers which only set their coherent DMA mask if the attempt to
           set the streaming mask fails.
         - drivers which test for a NULL dma mask pointer, and then set the
           dma mask pointer to a location in their module .data section -
           which will cause problems if the module is reloaded.
      
        To counter these, I have introduced two helper functions:
         - dma_set_mask_and_coherent() takes care of setting both the
           streaming and coherent masks at the same time, with the correct
           error handling as specified by the API.
         - dma_coerce_mask_and_coherent() which resolves the problem of
           drivers forcefully setting DMA masks.  This is more a marker for
           future work to further clean these locations up - the code which
           creates the devices really should be initialising these, but to fix
           that in one go along with this change could potentially be very
           disruptive.
      
        The last thing this series does is prise away some of Linux's addition
        to "DMA addresses are physical addresses and RAM always starts at
        zero".  We have ARM LPAE systems where all system memory is above 4GB
        physical, hence having DMA masks interpreted by (eg) the block layers
        as describing physical addresses in the range 0..DMAMASK fails on
        these platforms.  Santosh Shilimkar addresses this in this series; the
        patches were copied to the appropriate people multiple times but were
        ignored.
      
        Fixing this also gets rid of some ARM weirdness in the setup of the
        max*pfn variables, and brings ARM into line with every other Linux
        architecture as far as those go"

      Pull networking updates from David Miller:
      
       1) The addition of nftables.  No longer will we need protocol aware
          firewall filtering modules, it can all live in userspace.
      
          At the core of nftables is a, for lack of a better term, virtual
          machine that executes byte codes to inspect packet or metadata
          (arriving interface index, etc.) and make verdict decisions.
      
          Besides support for loading packet contents and comparing them, the
          interpreter supports lookups in various datastructures as
          fundamental operations.  For example sets are supports, and
          therefore one could create a set of whitelist IP address entries
          which have ACCEPT verdicts attached to them, and use the appropriate
          byte codes to do such lookups.
      
          Since the interpreted code is composed in userspace, userspace can
          do things like optimize things before giving it to the kernel.
      
          Another major improvement is the capability of atomically updating
          portions of the ruleset.  In the existing netfilter implementation,
          one has to update the entire rule set in order to make a change and
          this is very expensive.
      
          Userspace tools exist to create nftables rules using existing
          netfilter rule sets, but both kernel implementations will need to
          co-exist for quite some time as we transition from the old to the
          new stuff.
      
          Kudos to Patrick McHardy, Pablo Neira Ayuso, and others who have
          worked so hard on this.
      
       2) Daniel Borkmann and Hannes Frederic Sowa made several improvements
          to our pseudo-random number generator, mostly used for things like
          UDP port randomization and netfitler, amongst other things.
      
          In particular the taus88 generater is updated to taus113, and test
          cases are added.
      
       3) Support 64-bit rates in HTB and TBF schedulers, from Eric Dumazet
          and Yang Yingliang.
      
       4) Add support for new 577xx tigon3 chips to tg3 driver, from Nithin
          Sujir.
      
       5) Fix two fatal flaws in TCP dynamic right sizing, from Eric Dumazet,
          Neal Cardwell, and Yuchung Cheng.
      
       6) Allow IP_TOS and IP_TTL to be specified in sendmsg() ancillary
          control message data, much like other socket option attributes.
          From Francesco Fusco.
      
       7) Allow applications to specify a cap on the rate computed
          automatically by the kernel for pacing flows, via a new
          SO_MAX_PACING_RATE socket option.  From Eric Dumazet.
      
       8) Make the initial autotuned send buffer sizing in TCP more closely
          reflect actual needs, from Eric Dumazet.
      
       9) Currently early socket demux only happens for TCP sockets, but we
          can do it for connected UDP sockets too.  Implementation from Shawn
          Bohrer.
      
      10) Refactor inet socket demux with the goal of improving hash demux
          performance for listening sockets.  With the main goals being able
          to use RCU lookups on even request sockets, and eliminating the
          listening lock contention.  From Eric Dumazet.
      
      11) The bonding layer has many demuxes in it's fast path, and an RCU
          conversion was started back in 3.11, several changes here extend the
          RCU usage to even more locations.  From Ding Tianhong and Wang
          Yufen, based upon suggestions by Nikolay Aleksandrov and Veaceslav
          Falico.
      
      12) Allow stackability of segmentation offloads to, in particular, allow
          segmentation offloading over tunnels.  From Eric Dumazet.
      
      13) Significantly improve the handling of secret keys we input into the
          various hash functions in the inet hashtables, TCP fast open, as
          well as syncookies.  From Hannes Frederic Sowa.  The key fundamental
          operation is "net_get_random_once()" which uses static keys.
      
          Hannes even extended this to ipv4/ipv6 fragmentation handling and
          our generic flow dissector.
      
      14) The generic driver layer takes care now to set the driver data to
          NULL on device removal, so it's no longer necessary for drivers to
          explicitly set it to NULL any more.  Many drivers have been cleaned
          up in this way, from Jingoo Han.
      
      15) Add a BPF based packet scheduler classifier, from Daniel Borkmann.
      
      16) Improve CRC32 interfaces and generic SKB checksum iterators so that
          SCTP's checksumming can more cleanly be handled.  Also from Daniel
          Borkmann.
      
      17) Add a new PMTU discovery mode, IP_PMTUDISC_INTERFACE, which forces
          using the interface MTU value.  This helps avoid PMTU attacks,
          particularly on DNS servers.  From Hannes Frederic Sowa.
      
      18) Use generic XPS for transmit queue steering rather than internal
          (re-)implementation in virtio-net.  From Jason Wang.
