      tipc: re-configure queue limit for broadcast link · 75cee397
      Hoang Huu Le authored
      The queue limit of the broadcast link is being calculated base on initial
      MTU. However, when MTU value changed (e.g manual changing MTU on NIC
      device, MTU negotiation etc.,) we do not re-calculate queue limit.
      This gives throughput does not reflect with the change.
      
      So fix it by calling the function to re-calculate queue limit of the
      broadcast link.

      Pull networking updates from Jakub Kicinski:
      
       - Add redirect_neigh() BPF packet redirect helper, allowing to limit
         stack traversal in common container configs and improving TCP
         back-pressure.
      
         Daniel reports ~10Gbps => ~15Gbps single stream TCP performance gain.
      
       - Expand netlink policy support and improve policy export to user
         space. (Ge)netlink core performs request validation according to
         declared policies. Expand the expressiveness of those policies
         (min/max length and bitmasks). Allow dumping policies for particular
         commands. This is used for feature discovery by user space (instead
         of kernel version parsing or trial and error).
      
       - Support IGMPv3/MLDv2 multicast listener discovery protocols in
         bridge.
      
       - Allow more than 255 IPv4 multicast interfaces.
      
       - Add support for Type of Service (ToS) reflection in SYN/SYN-ACK
         packets of TCPv6.
      
       - In Multi-patch TCP (MPTCP) support concurrent transmission of data on
         multiple subflows in a load balancing scenario. Enhance advertising
         addresses via the RM_ADDR/ADD_ADDR options.
      
       - Support SMC-Dv2 version of SMC, which enables multi-subnet
         deployments.
      
       - Allow more calls to same peer in RxRPC.
      
       - Support two new Controller Area Network (CAN) protocols - CAN-FD and
         ISO 15765-2:2016.
      
       - Add xfrm/IPsec compat layer, solving the 32bit user space on 64bit
         kernel problem.
      
       - Add TC actions for implementing MPLS L2 VPNs.
      
       - Improve nexthop code - e.g. handle various corner cases when nexthop
         objects are removed from groups better, skip unnecessary
         notifications and make it easier to offload nexthops into HW by
         converting to a blocking notifier.
      
       - Support adding and consuming TCP header options by BPF programs,
         opening the doors for easy experimental and deployment-specific TCP
         option use.
      
       - Reorganize TCP congestion control (CC) initialization to simplify
         life of TCP CC implemented in BPF.
      
       - Add support for shipping BPF programs with the kernel and loading
         them early on boot via the User Mode Driver mechanism, hence reusing
         all the user space infra we have.
      
       - Support sleepable BPF programs, initially targeting LSM and tracing.
      
       - Add bpf_d_path() helper for returning full path for given 'struct
         path'.
      
       - Make bpf_tail_call compatible with bpf-to-bpf calls.
      
       - Allow BPF programs to call map_update_elem on sockmaps.
      
       - Add BPF Type Format (BTF) support for type and enum discovery, as
         well as support for using BTF within the kernel itself (current use
         is for pretty printing structures).
      
       - Support listing and getting information about bpf_links via the bpf
         syscall.
      
       - Enhance kernel interfaces around NIC firmware update. Allow
         specifying overwrite mask to control if settings etc. are reset
         during update; report expected max time operation may take to users;
         support firmware activation without machine reboot incl. limits of
         how much impact reset may have (e.g. dropping link or not).
      
       - Extend ethtool configuration interface to report IEEE-standard
         counters, to limit the need for per-vendor logic in user space.
      
       - Adopt or extend devlink use for debug, monitoring, fw update in many
         drivers (dsa loop, ice, ionic, sja1105, qed, mlxsw, mv88e6xxx,
         dpaa2-eth).
      
       - In mlxsw expose critical and emergency SFP module temperature alarms.
         Refactor port buffer handling to make the defaults more suitable and
         support setting these values explicitly via the DCBNL interface.
      
       - Add XDP support for Intel's igb driver.
      
       - Support offloading TC flower classification and filtering rules to
         mscc_ocelot switches.
      
       - Add PTP support for Marvell Octeontx2 and PP2.2 hardware, as well as
         fixed interval period pulse generator and one-step timestamping in
         dpaa-eth.
      
       - Add support for various auth offloads in WiFi APs, e.g. SAE (WPA3)
         offload.
      
       - Add Lynx PHY/PCS MDIO module, and convert various drivers which have
         this HW to use it. Convert mvpp2 to split PCS.
      
       - Support Marvell Prestera 98DX3255 24-port switch ASICs, as well as
         7-port Mediatek MT7531 IP.
      
       - Add initial support for QCA6390 and IPQ6018 in ath11k WiFi driver,
         and wcn3680 support in wcn36xx.
      
       - Improve performance for packets which don't require much offloads on
         recent Mellanox NICs by 20% by making multiple packets share a
         descriptor entry.
      
       - Move chelsio inline crypto drivers (for TLS and IPsec) from the
         crypto subtree to drivers/net. Move MDIO drivers out of the phy
         directory.
      
       - Clean up a lot of W=1 warnings, reportedly the actively developed
         subsections of networking drivers should now build W=1 warning free.
      
       - Make sure drivers don't use in_interrupt() to dynamically adapt their
         code. Convert tasklets to use new tasklet_setup API (sadly this
         conversion is not yet complete).

      bpf, selftest: Fix flaky tcp_hdr_options test when adding addr to lo · 8a3feed9
      Martin KaFai Lau authored
      The tcp_hdr_options test adds a "::eB9F" addr to the lo dev.
      However, this non loopback address will have a race on ipv6 dad
      which may lead to EADDRNOTAVAIL error from time to time.
      
      Even nodad is used in the iproute2 command, there is still a race in
      when the route will be added.  This will then lead to ENETUNREACH from
      time to time.
      
      To avoid the above, this patch uses the default loopback address "::1"
      to do the test.

      Add the necessary __acquires and __release annotations to make the
      iterator locking schema palatable to sparse. Also add __must_hold
      for good measure.
      
      The kernel codebase uses both __acquires(rcu) and __acquires(RCU).
      I couldn't find any guidance which one is preferred, so I used
      what is easier to type out.

      Many laptops can be woken up from Suspend-to-Idle by touchpad. This is
      also the default behavior on other OSes.
      
      However, if touchpad and touchscreen contact to each other when lid is
      closed, wakeup events can be triggered inadventertly.
      
      So let's disable the wakeup by default, but enable the wakeup capability
      so users can enable it at their own discretion.

      netfilter: nftables: allow re-computing sctp CRC-32C in 'payload' statements · 346e320c
      Davide Caratti authored
      nftables payload statements are used to mangle SCTP headers, but they can
      only replace the Internet Checksum. As a consequence, nftables rules that
      mangle sport/dport/vtag in SCTP headers potentially generate packets that
      are discarded by the receiver, unless the CRC-32C is "offloaded" (e.g the
      rule mangles a skb having 'ip_summed' equal to 'CHECKSUM_PARTIAL'.
      
      Fix this extending uAPI definitions and L4 checksum update function, in a
      way that userspace programs (e.g. nft) can instruct the kernel to compute
      CRC-32C in SCTP headers. Also ensure that LIBCRC32C is built if NF_TABLES
      is 'y' or 'm' in the kernel build configuration.

       "Not a major amount of change, the i915 trees got split into display
        and gt trees to better facilitate higher level review, and there's a
        major refactoring of i915 GEM locking to use more core kernel concepts
        (like ww-mutexes). msm gets per-process pagetables, older AMD SI cards
        get DC support, nouveau got a bump in displayport support with common
        code extraction from i915.
      
        Outside of drm this contains a couple of patches for hexint
        moduleparams which you've acked, and a virtio common code tree that

      net: fix pos incrementment in ipv6_route_seq_next · 6617dfd4
      Yonghong Song authored
      Commit 4fc427e0 ("ipv6_route_seq_next should increase position index")
      tried to fix the issue where seq_file pos is not increased
      if a NULL element is returned with seq_ops->next(). See bug
        https://bugzilla.kernel.org/show_bug.cgi?id=206283
      The commit effectively does:
        - increase pos for all seq_ops->start()
        - increase pos for all seq_ops->next()
      
      For ipv6_route, increasing pos for all seq_ops->next() is correct.
      But increasing pos for seq_ops->start() is not correct
      since pos is used to determine how many items to skip during
      seq_ops->start():
        iter->skip = *pos;
      seq_ops->start() just fetches the *current* pos item.
      The item can be skipped only after seq_ops->show() which essentially
      is the beginning of seq_ops->next().
      
      For example, I have 7 ipv6 route entries,
        root@arch-fb-vm1:~/net-next dd if=/proc/net/ipv6_route bs=4096

        root@arch-fb-vm1:~/net-next
      
      In the above, I specify buffer size 4096, so all records can be returned
      to user space with a single trip to the kernel.
      
      If I use buffer size 128, since each record size is 149, internally
      kernel seq_read() will read 149 into its internal buffer and return the data
      to user space in two read() syscalls. Then user read() syscall will trigger
      next seq_ops->start(). Since the current implementation increased pos even
      for seq_ops->start(), it will skip record #2, #4 and #6, assuming the first
      record is #1.

      To fix the problem, create a fake pos pointer so seq_ops->start()
      won't actually increase seq_file pos. With this fix, the
      above `dd` command with `bs=128` will show correct result.

      The first patch fixes a possible use-after-free of delayed llc events.
      Patch 2 corrects the number of DMB buffer sizes. And patch 3 ensures
      a correctly formatted return code when smc_ism_register_dmb() fails to

      net/smc: fix invalid return code in smcd_new_buf_create() · 6b1bbf94
      Karsten Graul authored
      smc_ism_register_dmb() returns error codes set by the ISM driver which
      are not guaranteed to be negative or in the errno range. Such values
      would not be handled by ERR_PTR() and finally the return code will be
      used as a memory address.
      Fix that by using a valid negative errno value with ERR_PTR().
