  • 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).

  • lance_interrupt() contains two pointless checks:

    - A check whether the 'dev_id' argument is NULL. 'dev_id' is the pointer
    which was handed in to request_irq() and the interrupt handler will
    always be invoked with that pointer as 'dev_id' argument by the core
    code.

    - A check for interrupt reentrancy. The core code already guarantees
    non-reentrancy of interrupt handlers.

    Remove these check.

  • The au1000-eth driver contains none of the manual cache synchronization
    required for using DMA_ATTR_NON_CONSISTENT. From what I can tell it
    can be used on both dma coherent and non-coherent DMA platforms, but
    I suspect it has been buggy on the non-coherent platforms all along.

  • Make use of the new udp_tunnel_nic infra. Don't clear the features
    when VxLAN port is not present to make all drivers behave the same.
    Driver will now (until we address the problem in the core) leave
    the RX UDP tunnel feature always on, since this is what most drivers
    do.

    Remove the list of VxLAN ports, just program the one core told us to.

    The driver seem to want to clear the VxLAN ports on close but it
    doesn't seem to flush the port list properly so it'd get wrong
    use counts after close/open. Again since it calls its own open
    handler we need the reset notification hack.

  • Instead of looping though the list of ports just check
    if the geometry of the packet is correct for VxLAN.
    HW most likely doesn't care about the exact port, anyway,
    since only first port is actually offloaded, and this way
    we won't have to maintain the port list at all.

  • The wrappers in include/linux/pci-dma-compat.h should go away.

    The patch has been generated with the coccinelle script below and has been
    hand modified to replace GPF_ with a correct flag.
    It has been compile tested.

    When memory is allocated in 'pcnet32_realloc_tx_ring()' and
    'pcnet32_realloc_rx_ring()', GFP_ATOMIC must be used because a spin_lock is
    hold.
    The call chain is:
    pcnet32_set_ringparam
    ** spin_lock_irqsave(&lp->lock, flags);
    --> pcnet32_realloc_tx_ring
    --> pcnet32_realloc_rx_ring
    ** spin_unlock_irqrestore(&lp->lock, flags);

    When memory is in 'pcnet32_probe1()' and 'pcnet32_alloc_ring()', GFP_KERNEL
    can be used.

    While at it, update a few comments and pr_err messages to be more in line
    with the new function names.

    The driver should support dev_pm_ops callbacks and bind them to pci_driver.

  • Remove legacy PM callbacks and use generic operations. With legacy code,
    drivers were responsible for handling PCI PM operations like
    pci_save_state(). In generic code, all these are handled by PCI core.

    The generic suspend() and resume() are called at the same point the legacy
    ones were called. Thus, it does not affect the normal functioning of the
    driver.

    Compile-tested only.

  • Since commit 84af7a6194e4 ("checkpatch: kconfig: prefer 'help' over
    '---help---'"), the number of '---help---' has been gradually
    decreasing, but there are still more than 2400 instances.

    This commit finishes the conversion. While I touched the lines,
    I also fixed the indentation.

    There are a variety of indentation styles found.

    a) 4 spaces + '---help---'
    b) 7 spaces + '---help---'
    c) 8 spaces + '---help---'
    d) 1 space + 1 tab + '---help---'
    e) 1 tab + '---help---' (correct indentation)
    f) 1 tab + 1 space + '---help---'
    g) 1 tab + 2 spaces + '---help---'

    In order to convert all of them to 1 tab + 'help', I ran the
    following commend:

    $ find . -name 'Kconfig*' | xargs sed -i 's/^[[:space:]]*---help---/\thelp/'

  • The current codebase makes use of the zero-length array language
    extension to the C90 standard, but the preferred mechanism to declare
    variable-length types such as these ones is a flexible array member[1][2],
    introduced in C99:

    struct foo {
    int stuff;
    struct boo array[];
    };

    By making use of the mechanism above, we will get a compiler warning
    in case the flexible array does not occur last in the structure, which
    will help us prevent some kind of undefined behavior bugs from being
    inadvertently introduced[3] to the codebase from now on.

    Also, notice that, dynamic memory allocations won't be affected by
    this change:

    "Flexible array members have incomplete type, and so the sizeof operator
    may not be applied. As a quirk of the original implementation of
    zero-length arrays, sizeof evaluates to zero."[1]

    sizeof(flexible-array-member) triggers a warning because flexible array
    members have incomplete type[1]. There are some instances of code in
    which the sizeof operator is being incorrectly/erroneously applied to
    zero-length arrays and the result is zero. Such instances may be hiding
    some bugs. So, this work (flexible-array member conversions) will also
    help to get completely rid of those sorts of issues.

    This issue was found with the help of Coccinelle.

  • The driver uses __napi_schedule_irqoff() which is fine as long as it is
    invoked with disabled interrupts by everybody. Since the commit
    mentioned below the driver may invoke xgbe_isr_task() in tasklet/softirq
    context. This may lead to list corruption if another driver uses
    __napi_schedule_irqoff() in IRQ context.

    Use __napi_schedule() which safe to use from IRQ and softirq context.

    then manually changing the few places which actually
    call ndo_tx_timeout.

  • Replace all the occurrences of FIELD_SIZEOF() with sizeof_field() except
    at places where these are defined. Later patches will remove the unused
    definition of FIELD_SIZEOF().

    This patch is generated using following script:

    EXCLUDE_FILES="include/linux/stddef.h|include/linux/kernel.h"

    git grep -l -e "\bFIELD_SIZEOF\b" | while read file;
    do

    if [[ "$file" =~ $EXCLUDE_FILES ]]; then
    continue
    fi
    sed -i -e 's/\bFIELD_SIZEOF\b/sizeof_field/g' $file;
    done

  • When calling debugfs functions, there is no need to ever check the
    return value. The function can work or not, but the code logic should
    never do something different based on this.

    This cleans up a lot of unneeded code and logic around the debugfs
    files, making all of this much simpler and easier to understand.
