      perf evlist: Add evlist__add_dummy_on_all_cpus() · 126d68fd
      Adrian Hunter authored
      Add evlist__add_dummy_on_all_cpus() to enable creating a system-wide dummy
      event that sets up the system-wide maps before map propagation.
      
      For convenience, add evlist__add_aux_dummy() so that the logic can be used
      whether or not the event needs to be system-wide.

      perf auxtrace: Add mmap_needed to auxtrace_mmap_params · d01508f2
      Adrian Hunter authored
      Add mmap_needed to auxtrace_mmap_params.
      
      Currently an auxtrace mmap is always attempted even if the event is not an
      auxtrace event. That works because, when AUX area tracing, there is always
      an auxtrace event first for every mmap. Prepare for that not being the
      case, which it won't be when sideband tracking events are allowed on
      all CPUs even when auxtrace is limited to selected CPUs.

      perf intel-pt: Add a test for system-wide side band · 1097b38f
      Adrian Hunter authored
      Add a test for system-wide side band even when tracing selected CPUs.
      
      The test fails before the patches up to "perf tools: Allow system-wide
      events to keep their own CPUs" are applied, passes afterwards.

      perf build: Stop using __weak bpf_map_create() to handle older libbpf versions · df76e003
      Arnaldo Carvalho de Melo authored
      By adding a feature test for bpf_map_create() and providing a fallback if
      it isn't present in older versions of libbpf.
      
      This also fixes the build with torvalds/master at this point:

      perf build: Fix btf__load_from_kernel_by_id() feature check · 73534617
      Jiri Olsa authored
      The btf__load_from_kernel_by_id() only takes one arg, not two.
      
      Committer notes:
      
      I tested it just with an older libbpf, one where
      btf__load_from_kernel_by_id() wasn't introduced yet.
      
      A test with a newer dynamic libbpf would fail because the
      btf__load_from_kernel_by_id() is there, but takes just one arg.

      Linus Torvalds authored
      Pull xfs updates from Dave Chinner:
       "This is a big update with lots of new code. The summary below them
        all, so I'll just touch on teh higlights. The two main new features
        are Large Extent Counts and Logged Attribute Replay - these are two
        new foundational features that we are building more complex future
        features on top of.
      
        For upcoming functionality, we need to be able to store hundreds of
        millions of xattrs per inode. The Large Extent Count feature removes
        the limits that prevent this scale of xattr storage, and while we were
        modifying the on disk extent count format we also increased the number
        of data extents we support per inode from 2^32 to 2^47.
      
        We also need to be able to modify xattrs as part of larger atomic
        transactions rather than as standalone transactions. The Logged
        Attribute Replay feature introduces the infrastructure that allows us
        to use intents to record the attribute modifications in the journal
        before we start them, hence allowing other atomic transactions to log
        attribute modification intents and then defer the actual modification
        to later. If we then crash, log recovery then guarantees that the
        attribute is replayed in the context of the atomic transaction that
        logged the intent.
      
        A significant chunk of the commits in this merge are for the base
        attribute replay functionality along with fixes, improvements and
        cleanups related to this new functioanlity. Allison deserves a big
        round of thanks for her ongoing work to get this functionality into
        XFS.
      
        There are also many other smaller changes and improvements, so overall
        this is one of the bigger XFS merge requests in some time.
      
        I will be following up next week with another smaller pull request -
        we already have another round of fixes and improvements to the logged
        attribute replay functionality just about ready to go. They'll soak
        and test over the next week, and I'll send a pull request for them
        near the end of the merge window.
      
        Summary:
      
         - support for printk message indexing.
      
         - large extent counts to provide support for up to 2^47 data extents
           and 2^32 attribute extents, allowing us to scale beyond 4 billion
           data extents to billions of xattrs per inode.
      
         - conversion of various flags fields to be consistently declared as
           unsigned bit fields.
      
         - improvements to realtime extent accounting and converts them to
           per-cpu counters to match all the other block and inode accounting.
      
         - reworks core log formatting code to reduce iterations, have a
           shorter, cleaner fast path and generally be easier to understand
           and maintain.
      
         - improvements to rmap btree searches that reduce overhead by up to
           30% resulting in xfs_scrub runtime reductions of 15%.
      
         - improvements to reflink that remove the size limitations in
           remapping operations and greatly reduce the size of transaction
           reservations.
      
         - reworks the minimum log size calculations to allow us to change
           transaction reservations without changing the minimum supported log
           size.
      
         - removal of quota warning support as it has never been used on
           Linux.
      
         - intent whiteouts to allow us to cancel intents that are completed
           entirely in memory rather than having use CPU and disk bandwidth
           formatting and writing them into the journal when it is not
           necessary. This makes rmap, reflink and extent freeing slightly
           more efficient, but provides massive improvements for....
      
         - Logged Attribute Replay feature support. This is a fundamental
           change to the way we modify attributes, laying the foundation for
           future integration of attribute modifications as part of other
           atomic transactional operations the filesystem performs.
      
         - Lots of cleanups and fixes for the logged attribute replay
           functionality"

      Pull networking updates from Jakub Kicinski:
       "Core
        ----
      
         - Support TCPv6 segmentation offload with super-segments larger than
           64k bytes using the IPv6 Jumbogram extension header (AKA BIG TCP).
      
         - Generalize skb freeing deferral to per-cpu lists, instead of
           per-socket lists.
      
         - Add a netdev statistic for packets dropped due to L2 address
           mismatch (rx_otherhost_dropped).
      
         - Continue work annotating skb drop reasons.
      
         - Accept alternative netdev names (ALT_IFNAME) in more netlink
           requests.
      
         - Add VLAN support for AF_PACKET SOCK_RAW GSO.
      
         - Allow receiving skb mark from the socket as a cmsg.
      
         - Enable memcg accounting for veth queues, sysctl tables and IPv6.
      
        BPF
        ---
      
         - Add libbpf support for User Statically-Defined Tracing (USDTs).
      
         - Speed up symbol resolution for kprobes multi-link attachments.
      
         - Support storing typed pointers to referenced and unreferenced
           objects in BPF maps.
      
         - Add support for BPF link iterator.
      
         - Introduce access to remote CPU map elements in BPF per-cpu map.
      
         - Allow middle-of-the-road settings for the
           kernel.unprivileged_bpf_disabled sysctl.
      
         - Implement basic types of dynamic pointers e.g. to allow for
           dynamically sized ringbuf reservations without extra memory copies.
      
        Protocols
        ---------
      
         - Retire port only listening_hash table, add a second bind table
           hashed by port and address. Avoid linear list walk when binding to
           very popular ports (e.g. 443).
      
         - Add bridge FDB bulk flush filtering support allowing user space to
           remove all FDB entries matching a condition.
      
         - Introduce accept_unsolicited_na sysctl for IPv6 to implement
           router-side changes for RFC9131.
      
         - Support for MPTCP path manager in user space.
      
         - Add MPTCP support for fallback to regular TCP for connections that
           have never connected additional subflows or transmitted
           out-of-sequence data (partial support for RFC8684 fallback).
      
         - Avoid races in MPTCP-level window tracking, stabilize and improve
           throughput.
      
         - Support lockless operation of GRE tunnels with seq numbers enabled.
      
         - WiFi support for host based BSS color collision detection.
      
         - Add support for SO_TXTIME/SCM_TXTIME on CAN sockets.
      
         - Support transmission w/o flow control in CAN ISOTP (ISO 15765-2).
      
         - Support zero-copy Tx with TLS 1.2 crypto offload (sendfile).
      
         - Allow matching on the number of VLAN tags via tc-flower.
      
         - Add tracepoint for tcp_set_ca_state().
      
        Driver API
        ----------
      
         - Improve error reporting from classifier and action offload.
      
         - Add support for listing line cards in switches (devlink).
      
         - Add helpers for reporting page pool statistics with ethtool -S.
      
         - Add support for reading clock cycles when using PTP virtual clocks,
           instead of having the driver convert to time before reporting. This
           makes it possible to report time from different vclocks.
      
         - Support configuring low-latency Tx descriptor push via ethtool.
      
         - Separate Clause 22 and Clause 45 MDIO accesses more explicitly.

       - Offload writing printk() messages on consoles to per-console
         kthreads.
      
         It prevents soft-lockups when an extensive amount of messages is
         printed. It was observed, for example, during boot of large systems
         with a lot of peripherals like disks or network interfaces.
      
         It prevents live-lockups that were observed, for example, when
         messages about allocation failures were reported and a CPU handled
         consoles instead of reclaiming the memory. It was hard to solve even
         with rate limiting because it would need to take into account the
         amount of messages and the speed of all consoles.
      
         It is a must to have for real time. Otherwise, any printk() might
         break latency guarantees.
      
         The per-console kthreads allow to handle each console on its own
         speed. Slow consoles do not longer slow down faster ones. And
         printk() does not longer unpredictably slows down various code paths.
      
         There are situations when the kthreads are either not available or
         not reliable, for example, early boot, suspend, or panic. In these
         situations, printk() uses the legacy mode and tries to handle
         consoles immediately.
      
       - Add documentation for the printk index.

       - Conversion of slub_debug stack traces to stackdepot, allowing more
         useful debugfs-based inspection for e.g. memory leak debugging.
         Allocation and free debugfs info now includes full traces and is
         sorted by the unique trace frequency.
      
         The stackdepot conversion was already attempted last year but
         reverted by ae14c63a. The memory overhead (while not actually
         enabled on boot) has been meanwhile solved by making the large
         stackdepot allocation dynamic. The xfstest issues haven't been
         reproduced on current kernel locally nor in -next, so the slab cache
         layout changes that originally made that bug manifest were probably
         not the root cause.

      linux/types.h: reinstate "__bitwise__" macro for user space use · caa28984
      Linus Torvalds authored
      Commit c724c866 ("linux/types.h: remove unnecessary __bitwise__")
      was right that there are no users of __bitwise__ in the kernel, but it
      turns out there are user space users of it that do expect it.
      
      It is, after all, in the uapi directory, so user space usage is to be
      expected.
      
      Instead of reverting the commit completely, let's just clarify the
      situation so that it doesn't happen again, and have some in-code
      explanations for why that "__bitwise__" still exists.

       "There's a couple of corrections sent in by Andreas for some accounting
        errors.
      
        The biggest change this time around is that writeback errors longer
        clear pageuptodate nor does XFS invalidate the page cache anymore.
        This brings XFS (and gfs2/zonefs) behavior in line with every other
        Linux filesystem driver, and fixes some UAF bugs that only cropped up
        after willy turned on multipage folios for XFS in 5.18-rc1.
      
        Regrettably, it took all the way to the end of the 5.18 cycle to find
        the source of these bugs and reach a consensus that XFS' writeback
        failure behavior from 20 years ago is no longer necessary.
      
        Summary:
      
         - Fix a couple of accounting errors in the buffered io code.
      
         - Discontinue the practice of marking folios !uptodate and
           invalidating them when writeback fails.
      
           This fixes some UAF bugs when multipage folios are enabled, and
           brings the behavior of XFS/gfs/zonefs into alignment with the
           behavior of all the other Linux filesystems"
