Add the missing pieces to allow multiple PPEs units, one for each GMAC. mtk_gdm_config has been modified to work on targted mac ID, the inner loop moved outside of the function to allow unrelated operations like setting the MAC's PPE index. Introduce a sanity check in flow_offload_replace to account for non-MTK ingress devices. Additional field 'ppe_idx' was added to struct mtk_mac in order to keep track on the assigned PPE unit.

Petr Machata says: ==================== Allow configuration of multipath hash seed Let me just quote the commit message of patch #2 here to inform the motivation and some of the implementation: When calculating hashes for the purpose of multipath forwarding, both IPv4 and IPv6 code currently fall back on flow_hash_from_keys(). That uses a randomly-generated seed. That's a fine choice by default, but unfortunately some deployments may need a tighter control over the seed used. In this patchset, make the seed configurable by adding a new sysctl key, net.ipv4.fib_multipath_hash_seed to control the seed. This seed is used specifically for multipath forwarding and not for the other concerns that flow_hash_from_keys() is used for, such as queue selection. Expose the knob as sysctl because other such settings, such as headers to hash, are also handled that way. Despite being placed in the net.ipv4 namespace, the multipath seed sysctl is used for both IPv4 and IPv6, similarly to e.g. a number of TCP variables. Like those, the multipath hash seed is a per-netns variable. The seed used by flow_hash_from_keys() is a 128-bit quantity. However it seems that usually the seed is a much more modest value. 32 bits seem typical (Cisco, Cumulus), some systems go even lower. For that reason, and to decouple the user interface from implementation details, go with a 32-bit quantity, which is then quadruplicated to form the siphash key. One example of use of this interface is avoiding hash polarization, where two ECMP routers, one behind the other, happen to make consistent hashing decisions, and as a result, part of the ECMP space of the latter router is never used. Another is a load balancer where several machines forward traffic to one of a number of leaves, and the forwarding decisions need to be made consistently. (This is a case of a desired hash polarization, mentioned e.g. in chapter 6.3 of [0].) There has already been a proposal to include a hash seed control interface in the past[1]. - Patches #1-#2 contain the substance of the work - Patch #3 is an mlxsw offload - Patches #4 and #5 are a selftest [0] https://www.usenix.org/system/files/conference/nsdi18/nsdi18-araujo.pdf [1] https://lore.kernel.org/netdev/YIlVpYMCn%2F8WfE1P@rnd/ ==================== Link: https://lore.kernel.org/r/20240607151357.421181-1-petrm@nvidia.comSigned-off-by: -

Years ago flow dissector gained ability to delegate flow dissection to a bpf program, scoped per netns. Unfortunately, skb_get_hash() only gets an sk_buff argument instead of both net+skb. This means the flow dissector needs to obtain the netns pointer from somewhere else. The netns is derived from skb->dev, and if that is not available, from skb->sk. If neither is set, we hit a (benign) WARN_ON_ONCE(). Trying both dev and sk covers most cases, but not all, as recently reported by Christoph Paasch. In case of nf-generated tcp reset, both sk and dev are NULL: WARNING: .. net/core/flow_dissector.c:1104 skb_flow_dissect_flow_keys include/linux/skbuff.h:1536 [inline] skb_get_hash include/linux/skbuff.h:1578 [inline] nft_trace_init+0x7d/0x120 net/netfilter/nf_tables_trace.c:320 nft_do_chain+0xb26/0xb90 net/netfilter/nf_tables_core.c:268 nft_do_chain_ipv4+0x7a/0xa0 net/netfilter/nft_chain_filter.c:23 nf_hook_slow+0x57/0x160 net/netfilter/core.c:626 __ip_local_out+0x21d/0x260 net/ipv4/ip_output.c:118 ip_local_out+0x26/0x1e0 net/ipv4/ip_output.c:127 nf_send_reset+0x58c/0x700 net/ipv4/netfilter/nf_reject_ipv4.c:308 nft_reject_ipv4_eval+0x53/0x90 net/ipv4/netfilter/nft_reject_ipv4.c:30 [..] syzkaller did something like this: table inet filter { chain input { type filter hook input priority filter; policy accept; meta nftrace set 1 tcp dport 42 reject with tcp reset } chain output { type filter hook output priority filter; policy accept; # empty chain is enough } } ... then sends a tcp packet to port 42. Initial attempt to simply set skb->dev from nf_reject_ipv4 doesn't cover all cases: skbs generated via ipv4 igmp_send_report trigger similar splat. Moreover, Pablo Neira found that nft_hash.c uses __skb_get_hash_symmetric() which would trigger same warn splat for such skbs. Lets allow callers to pass the current netns explicitly. The nf_trace infrastructure is adjusted to use the new helper. __skb_get_hash_symmetric is handled in the next patch.

Instead of forcing userspace to parse dmesg (that's what currently is happening, at least in codebase of my current company), provide a better way, that can be enabled/disabled in runtime. Currently, there are already tcp events, add hashing related ones there, too. Rasdaemon currently exercises net_dev_xmit_timeout, devlink_health_report, but it'll be trivial to teach it to deal with failed hashes. Otherwise, BGP may trace/log them itself. Especially exciting for possible investigations is key rotation (RNext_key requests). Suggested-by:

The helper setup_ns() doesn't work when a net namespace named "ns" is passed to it. For example, in net/mptcp/diag.sh, the name of the namespace is "ns". If "setup_ns ns" is used in it, diag.sh fails with errors: Invalid netns name "./mptcp_connect" Cannot open network namespace "10000": No such file or directory Cannot open network namespace "10000": No such file or directory That is because "ns" is also a local variable in setup_ns, and it will not set the value for the global variable that has been giving in argument. To solve this, we could rename the variable, but it sounds better to drop it, as we can resolve the name using the variable passed in argument instead. The other local variables -- "ns_list" and "ns_name" -- are more unlikely to conflict with existing global variables. They don't seem to be currently used in any other net selftests. Co-developed-by:

It sounds good to mark the global netns variable as 'readonly', but Bash doesn't allow the creation of local variables with the same name. Because it looks like 'readonly' is mainly used here to check if a netns with that name has already been set, it sounds fine to check if a variable with this name has already been set instead. By doing that, we avoid having to modify helpers from MPTCP selftests using the same variable name as the one used to store the created netns name. While at it, also avoid an unnecessary call to 'eval' to set a local variable. Reviewed-by:

Move ip_tunnel driver to leverage the core allocation. All the ip_tunnel_init() users call ip_tunnel_init() as part of their .ndo_init callback.

irq_set_affinity_hint() is deprecated. Use irq_update_affinity_hint() instead. This removes the side-effect of actually applying the affinity. The driver does not really need to worry about spreading its IRQs across CPUs. The core code already takes care of that. On the contrary, when the driver applies affinities by itself, it breaks the users' expectations: 1. The user configures irqbalance with IRQBALANCE_BANNED_CPULIST in order to prevent IRQs from being moved to certain CPUs that run a real-time workload. 2. ice reconfigures VSIs at runtime due to a MIB change (ice_dcb_process_lldp_set_mib_change). Reopening a VSI resets the affinity in ice_vsi_req_irq_msix(). 3. ice has no idea about irqbalance's config, so it may move an IRQ to a banned CPU. The real-time workload suffers unacceptable latency. I am not sure if updating the affinity hints is at all useful, because irqbalance ignores them since 2016 ([1]), but at least it's harmless. This ice change is similar to i40e commit d34c54d1 ("i40e: Use irq_update_affinity_hint()").

In ice_ptp_cfg_clkout(), the ice driver needs to calculate the nearest next second of a current time value specified in nanoseconds. It implements this using div64_u64, because the time value is a u64. It could use div_u64 since NSEC_PER_SEC is smaller than 32-bits. Ideally this would be implemented directly with roundup(), but that can't work on all platforms due to a division which requires using the specific macros and functions due to platform restrictions, and to ensure that the most appropriate and fast instructions are used. The kernel doesn't currently provide any 64-bit equivalents for doing roundup. Attempting to use roundup() on a 32-bit platform will result in a link failure due to not having a direct 64-bit division. The closest equivalent for this is DIV64_U64_ROUND_UP, which does a division always rounding up. However, this only computes the division, and forces use of the div64_u64 in cases where the divisor is a 32bit value and could make use of div_u64. Introduce DIV_U64_ROUND_UP based on div_u64, and then use it to implement roundup_u64 which takes a u64 input value and a u32 rounding value. The name roundup_u64 matches the naming scheme of div_u64, and future patches could implement roundup64_u64 if they need to round by a multiple that is greater than 32-bits. Replace the logic in ice_ptp.c which does this equivalent with the newly added roundup_u64. Tested-by:

The main changes are: 1) Add a user space notification mechanism via epoll when a struct_ops object is getting detached/unregistered, from Kui-Feng Lee. 2) Big batch of BPF selftest refactoring for sockmap and BPF congctl tests, from Geliang Tang. 3) Add BTF field (type and string fields, right now) iterator support to libbpf instead of using existing callback-based approaches, from Andrii Nakryiko. 4) Extend BPF selftests for the latter with a new btf_field_iter selftest, from Alan Maguire. 5) Add new kfuncs for a generic, open-coded bits iterator, from Yafang Shao. 6) Fix BPF selftests' kallsyms_find() helper under kernels configured with CONFIG_LTO_CLANG_THIN, from Yonghong Song. 7) Remove a bunch of unused structs in BPF selftests, from David Alan Gilbert. 8) Convert test_sockmap section names into names understood by libbpf so it can deduce program type and attach type, from Jakub Sitnicki. 9) Extend libbpf with the ability to configure log verbosity via LIBBPF_LOG_LEVEL environment variable, from Mykyta Yatsenko. 10) Fix BPF selftests with regards to bpf_cookie and find_vma flakiness in nested VMs, from Song Liu. 11) Extend riscv32/64 JITs to introduce shift/add helpers to generate Zba optimization, from Xiao Wang. 12) Enable BPF programs to declare arrays and struct fields with kptr, bpf_rb_root, and bpf_list_head, from Kui-Feng Lee. * tag 'for-netdev' of https://git.kernel.org/pub/scm/linux/kernel/git/bpf/bpf-next: (54 commits) selftests/bpf: Drop useless arguments of do_test in bpf_tcp_ca selftests/bpf: Use start_test in test_dctcp in bpf_tcp_ca selftests/bpf: Use start_test in test_dctcp_fallback in bpf_tcp_ca selftests/bpf: Add start_test helper in bpf_tcp_ca selftests/bpf: Use connect_to_fd_opts in do_test in bpf_tcp_ca libbpf: Auto-attach struct_ops BPF maps in BPF skeleton selftests/bpf: Add btf_field_iter selftests selftests/bpf: Fix send_signal test with nested CONFIG_PARAVIRT libbpf: Remove callback-based type/string BTF field visitor helpers bpftool: Use BTF field iterator in btfgen libbpf: Make use of BTF field iterator in BTF handling code libbpf: Make use of BTF field iterator in BPF linker code libbpf: Add BTF field iterator selftests/bpf: Ignore .llvm.<hash> suffix in kallsyms_find() selftests/bpf: Fix bpf_cookie and find_vma in nested VM selftests/bpf: Test global bpf_list_head arrays. selftests/bpf: Test global bpf_rb_root arrays and fields in nested struct types. selftests/bpf: Test kptr arrays and kptrs in nested struct fields. bpf: limit the number of levels of a nested struct type. bpf: look into the types of the fields of a struct type recursively. ... ==================== Link: https://lore.kernel.org/r/20240606223146.23020-1-daniel@iogearbox.netSigned-off-by: -

Marek Behún says: ==================== Fix changing DSA conduit This series fixes an issue in the DSA code related to host interface UC address installed into port FDB and port conduit address database when live-changing port conduit. The first patch refactores/deduplicates the installation/uninstallation of the interface's MAC address and the second patch fixes the issue.
