2025-07-25selftests: netfilter: Enable CONFIG_INET_SCTP_DIAGSebastian Andrzej Siewior
The config snippet specifies CONFIG_SCTP_DIAG. This was never an option. Replace CONFIG_SCTP_DIAG with the intended CONFIG_INET_SCTP_DIAG. Signed-off-by: Sebastian Andrzej Siewior <bigeasy@linutronix.de> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
2025-07-25selftests: net: Enable legacy netfilter legacy options.Florian Westphal
Some specified options rely on NETFILTER_XTABLES_LEGACY to be enabled. IP_NF_TARGET_TTL for instance depends on IP_NF_MANGLE which in turn depends on IP_NF_IPTABLES_LEGACY -> NETFILTER_XTABLES_LEGACY. Enable relevant iptables config options explicitly, this is needed to avoid breakage when symbols related to iptables-legacy will depend on NETFILTER_LEGACY resp. IP_TABLES_LEGACY. This also means that the classic tables (Kernel modules) will not be enabled by default, so enable them too.

2025-07-25netfilter: Exclude LEGACY TABLES on PREEMPT_RT.Pablo Neira Ayuso
The seqcount xt_recseq is used to synchronize the replacement of xt_table::private in xt_replace_table() against all readers such as ipt_do_table() To ensure that there is only one writer, the writing side disables bottom halves. The sequence counter can be acquired recursively. Only the first invocation modifies the sequence counter (signaling that a writer is in progress) while the following (recursive) writer does not modify the counter. The lack of a proper locking mechanism for the sequence counter can lead to live lock on PREEMPT_RT if the high prior reader preempts the writer. Additionally if the per-CPU lock on PREEMPT_RT is removed from local_bh_disable() then there is no synchronisation for the per-CPU sequence counter. The affected code is "just" the legacy netfilter code which is replaced by "netfilter tables". That code can be disabled without sacrificing functionality because everything is provided by the newer implementation. This will only requires the usage of the "-nft" tools instead of the "-legacy" ones. The long term plan is to remove the legacy code so lets accelerate the progress. Relax dependencies on iptables legacy, replace select with depends on, this should cause no harm to existing kernel configs and users can still toggle IP{6}_NF_IPTABLES_LEGACY in any case. Make EBTABLES_LEGACY, IPTABLES_LEGACY and ARPTABLES depend on NETFILTER_XTABLES_LEGACY. Hide xt_recseq and its users, xt_register_table() and xt_percpu_counter_alloc() behind NETFILTER_XTABLES_LEGACY. Let NETFILTER_XTABLES_LEGACY depend on !PREEMPT_RT. This will break selftest expecing the legacy options enabled and will be addressed in a following patch.

2025-07-24selftests: drv-net: Make command requirements explicitGal Pressman
Make require_cmd() calls explicit about whether commands are needed locally, remotely, or both. Since require_cmd() defaults to local=True, tests should explicitly set local=False when commands are only needed remotely. - socat: Set local=False since it's only needed on remote hosts. - iperf3: Use single call with both local=True and remote=True since it's needed on both hosts. This avoids unnecessary test failures when commands are missing locally but available remotely where actually needed, and consolidates a duplicate require_cmd() call into single call that checks both hosts.

2025-07-24net/mlx5: Fix build -Wframe-larger-than warningsZhu Yanjun
When building, the following warnings will appear. " pci_irq.c: In function ‘mlx5_ctrl_irq_request’: pci_irq.c:494:1: warning: the frame size of 1040 bytes is larger than 1024 bytes [-Wframe-larger-than=] pci_irq.c: In function ‘mlx5_irq_request_vector’: pci_irq.c:561:1: warning: the frame size of 1040 bytes is larger than 1024 bytes [-Wframe-larger-than=] eq.c: In function ‘comp_irq_request_sf’: eq.c:897:1: warning: the frame size of 1080 bytes is larger than 1024 bytes [-Wframe-larger-than=] irq_affinity.c: In function ‘irq_pool_request_irq’: irq_affinity.c:74:1: warning: the frame size of 1048 bytes is larger than 1024 bytes [-Wframe-larger-than=] " These warnings indicate that the stack frame size exceeds 1024 bytes in these functions. To resolve this, instead of allocating large memory buffers on the stack, it is better to use kvzalloc to allocate memory dynamically on the heap. This approach reduces stack usage and eliminates these frame size warnings.

Prepare for adding an enum type for NAPI threaded states by adding netif_threaded_enable API. De-export the existing netif_set_threaded API and only use it internally. Update existing drivers to use netif_threaded_enable instead of the de-exported netif_set_threaded. Note that dev_set_threaded used by mt76 debugfs file is unchanged.

2025-07-24tools: ynl-gen: print setters for multi-val attrsJakub Kicinski
For basic types we "flatten" setters. If a request "a" has a simple nest "b" with value "val" we print helpers like: req_set_a_b(struct a *req, int val) { req->_present.a = 1; req->b._present.val = 1; req->b.val = ... } This is not possible for multi-attr because they have to be allocated dynamically by the user. Print "object level" setters so that user preparing the object doesn't have to futz with the presence bits and other YNL internals. Add the ability to pass in the variable name to generated setters. Using "req" here doesn't feel right, while the attr is part of a request it's not the request itself, so it seems cleaner to call it "obj". Example: static inline void netdev_queue_id_set_id(struct netdev_queue_id *obj, __u32 id) { obj->_present.id = 1; obj->id = id; } Reviewed-by: Donald Hunter <donald.hunter@gmail.com> Acked-by: Stanislav Fomichev <sdf@fomichev.me> Link: https://patch.msgid.link/20250723171046.4027470-5-kuba@kernel.org Signed-off-by: Jakub Kicinski <kuba@kernel.org>
2025-07-24tools: ynl-gen: print alloc helper for multi-val attrsJakub Kicinski
In general YNL provides allocation and free helpers for types. For pure nested structs which are used as multi-attr (and therefore have to be allocated dynamically) we already print a free helper as it's needed by free of the containing struct. Add printing of the alloc helper for consistency. The helper takes the number of entries to allocate as an argument, e.g.: static inline struct netdev_queue_id *netdev_queue_id_alloc(unsigned int n) { return calloc(n, sizeof(struct netdev_queue_id)); } Reviewed-by: Donald Hunter <donald.hunter@gmail.com> Acked-by: Stanislav Fomichev <sdf@fomichev.me> Link: https://patch.msgid.link/20250723171046.4027470-4-kuba@kernel.org Signed-off-by: Jakub Kicinski <kuba@kernel.org>
