Merge tag 'net-next-6.3' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-nextgrafted
Pull networking updates from Jakub Kicinski:
"Core:
- Add dedicated kmem_cache for typical/small skb->head, avoid having
to access struct page at kfree time, and improve memory use.
- Introduce sysctl to set default RPS configuration for new netdevs.
- Define Netlink protocol specification format which can be used to
describe messages used by each family and auto-generate parsers.
Add tools for generating kernel data structures and uAPI headers.
- Expose all net/core sysctls inside netns.
- Remove 4s sleep in netpoll if carrier is instantly detected on
boot.
- Add configurable limit of MDB entries per port, and port-vlan.
- Continue populating drop reasons throughout the stack.
- Retire a handful of legacy Qdiscs and classifiers.
Protocols:
- Support IPv4 big TCP (TSO frames larger than 64kB).
- Add IP_LOCAL_PORT_RANGE socket option, to control local port range
on socket by socket basis.
- Track and report in procfs number of MPTCP sockets used.
- Support mixing IPv4 and IPv6 flows in the in-kernel MPTCP path
manager.
- IPv6: don't check net.ipv6.route.max_size and rely on garbage
collection to free memory (similarly to IPv4).
- Support Penultimate Segment Pop (PSP) flavor in SRv6 (RFC8986).
- ICMP: add per-rate limit counters.
- Add support for user scanning requests in ieee802154.
- Remove static WEP support.
- Support minimal Wi-Fi 7 Extremely High Throughput (EHT) rate
reporting.
- WiFi 7 EHT channel puncturing support (client & AP).
BPF:
- Add a rbtree data structure following the "next-gen data structure"
precedent set by recently added linked list, that is, by using
kfunc + kptr instead of adding a new BPF map type.
- Expose XDP hints via kfuncs with initial support for RX hash and
timestamp metadata.
- Add BPF_F_NO_TUNNEL_KEY extension to bpf_skb_set_tunnel_key to
better support decap on GRE tunnel devices not operating in collect
metadata.
- Improve x86 JIT's codegen for PROBE_MEM runtime error checks.
- Remove the need for trace_printk_lock for bpf_trace_printk and
bpf_trace_vprintk helpers.
- Extend libbpf's bpf_tracing.h support for tracing arguments of
kprobes/uprobes and syscall as a special case.
- Significantly reduce the search time for module symbols by
livepatch and BPF.
- Enable cpumasks to be used as kptrs, which is useful for tracing
programs tracking which tasks end up running on which CPUs in
different time intervals.
- Add support for BPF trampoline on s390x and riscv64.
- Add capability to export the XDP features supported by the NIC.
- Add __bpf_kfunc tag for marking kernel functions as kfuncs.
- Add cgroup.memory=nobpf kernel parameter option to disable BPF
memory accounting for container environments.
Netfilter:
- Remove the CLUSTERIP target. It has been marked as obsolete for
years, and we still have WARN splats wrt races of the out-of-band
/proc interface installed by this target.
- Add 'destroy' commands to nf_tables. They are identical to the
existing 'delete' commands, but do not return an error if the
referenced object (set, chain, rule...) did not exist.
Driver API:
- Improve cpumask_local_spread() locality to help NICs set the right
IRQ affinity on AMD platforms.
- Separate C22 and C45 MDIO bus transactions more clearly.
- Introduce new DCB table to control DSCP rewrite on egress.
- Support configuration of Physical Layer Collision Avoidance (PLCA)
Reconciliation Sublayer (RS) (802.3cg-2019). Modern version of
shared medium Ethernet.
- Support for MAC Merge layer (IEEE 802.3-2018 clause 99). Allowing
preemption of low priority frames by high priority frames.
- Add support for controlling MACSec offload using netlink SET.
- Rework devlink instance refcounts to allow registration and
de-registration under the instance lock. Split the code into
multiple files, drop some of the unnecessarily granular locks and
factor out common parts of netlink operation handling.
- Add TX frame aggregation parameters (for USB drivers).
- Add a new attr TCA_EXT_WARN_MSG to report TC (offload) warning
messages with notifications for debug.
- Allow offloading of UDP NEW connections via act_ct.
- Add support for per action HW stats in TC.
- Support hardware miss to TC action (continue processing in SW from
a specific point in the action chain).
- Warn if old Wireless Extension user space interface is used with
modern cfg80211/mac80211 drivers. Do not support Wireless
Extensions for Wi-Fi 7 devices at all. Everyone should switch to
using nl80211 interface instead.
- Improve the CAN bit timing configuration. Use extack to return
error messages directly to user space, update the SJW handling,
including the definition of a new default value that will benefit
CAN-FD controllers, by increasing their oscillator tolerance.

Non dipendente dal fatto che un file + d'intestazione include anche quelli usati da voi. + +2) Compilazione pulita: + + a) con le opzioni ``CONFIG`` negli stati ``=y``, ``=m`` e ``=n``. Nessun + avviso/errore di ``gcc`` e nessun avviso/errore dal linker. + + b) con ``allnoconfig``, ``allmodconfig`` + + c) quando si usa ``O=builddir`` + + d) Qualsiasi modifica in Documentation/ deve compilare con successo senza + avvisi o errori. Usare ``make htmldocs`` o ``make pdfdocs`` per verificare + e correggere i problemi + +3) Compilare per diverse architetture di processore usando strumenti per + la cross-compilazione o altri. + +4) Una buona architettura per la verifica della cross-compilazione è la ppc64 + perché tende ad usare ``unsigned long`` per le quantità a 64-bit. + +5) Controllate lo stile del codice della vostra patch secondo le direttive + scritte in :ref:`Documentation/translations/it_IT/process/coding-style.rst <it_codingstyle>`. + Prima dell'invio della patch, usate il verificatore di stile + (``script/checkpatch.pl``) per scovare le violazioni più semplici. + Dovreste essere in grado di giustificare tutte le violazioni rimanenti nella + vostra patch. + +6) Le opzioni ``CONFIG``, nuove o modificate, non scombussolano il menu + di configurazione e sono preimpostate come disabilitate a meno che non + soddisfino i criteri descritti in ``Documentation/kbuild/kconfig-language.rst`` + alla punto "Voci di menu: valori predefiniti". + +7) Tutte le nuove opzioni ``Kconfig`` hanno un messaggio di aiuto. + +8) La patch è stata accuratamente revisionata rispetto alle più importanti + configurazioni ``Kconfig``. Questo è molto difficile da fare + correttamente - un buono lavoro di testa sarà utile. + +9) Verificare con sparse. + +10) Usare ``make checkstack`` e correggere tutti i problemi rilevati. + + .. note:: + + ``checkstack`` non evidenzia esplicitamente i problemi, ma una funzione + che usa più di 512 byte sullo stack è una buona candidata per una + correzione. + +11) Includete commenti :ref:`kernel-doc <kernel_doc>` per documentare API + globali del kernel. Usate ``make htmldocs`` o ``make pdfdocs`` per + verificare i commenti :ref:`kernel-doc <kernel_doc>` ed eventualmente + correggerli. + +12) La patch è stata verificata con le seguenti opzioni abilitate + contemporaneamente: ``CONFIG_PREEMPT``, ``CONFIG_DEBUG_PREEMPT``, + ``CONFIG_DEBUG_SLAB``, ``CONFIG_DEBUG_PAGEALLOC``, ``CONFIG_DEBUG_MUTEXES``, + ``CONFIG_DEBUG_SPINLOCK``, ``CONFIG_DEBUG_ATOMIC_SLEEP``, + ``CONFIG_PROVE_RCU`` e ``CONFIG_DEBUG_OBJECTS_RCU_HEAD``. + +13) La patch è stata compilata e verificata in esecuzione con, e senza, + le opzioni ``CONFIG_SMP`` e ``CONFIG_PREEMPT``. + +14) Se la patch ha effetti sull'IO dei dischi, eccetera: allora dev'essere + verificata con, e senza, l'opzione ``CONFIG_LBDAF``. + +15) Tutti i percorsi del codice sono stati verificati con tutte le funzionalità + di lockdep abilitate. + +16) Tutti i nuovi elementi in ``/proc`` sono documentati in ``Documentation/``. + +17) Tutti i nuovi parametri d'avvio del kernel sono documentati in + ``Documentation/admin-guide/kernel-parameters.rst``. + +18) Tutti i nuovi parametri dei moduli sono documentati con ``MODULE_PARM_DESC()``. + +19) Tutte le nuove interfacce verso lo spazio utente sono documentate in + ``Documentation/ABI/``. Leggete ``Documentation/ABI/README`` per maggiori + informazioni. Le patch che modificano le interfacce utente dovrebbero + essere inviate in copia anche a linux-api@vger.kernel.org. + +20) La patch è stata verificata con l'iniezione di fallimenti in slab e + nell'allocazione di pagine. Vedere ``Documentation/fault-injection/``. + + Se il nuovo codice è corposo, potrebbe essere opportuno aggiungere + l'iniezione di fallimenti specifici per il sottosistema. + +21) Il nuovo codice è stato compilato con ``gcc -W`` (usate + ``make KCFLAGS=-W``). Questo genererà molti avvisi, ma è ottimo + per scovare bachi come "warning: comparison between signed and unsigned". + +22) La patch è stata verificata dopo essere stata inclusa nella serie di patch + -mm; questo al fine di assicurarsi che continui a funzionare assieme a + tutte le altre patch in coda e i vari cambiamenti nei sottosistemi VM, VFS + e altri. + +23) Tutte le barriere di sincronizzazione {per esempio, ``barrier()``, + ``rmb()``, ``wmb()``} devono essere accompagnate da un commento nei + sorgenti che ne spieghi la logica: cosa fanno e perché. + +24) Se la patch aggiunge nuove chiamate ioctl, allora aggiornate + ``Documentation/userspace-api/ioctl/ioctl-number.rst``. + +25) Se il codice che avete modificato dipende o usa una qualsiasi interfaccia o + funzionalità del kernel che è associata a uno dei seguenti simboli + ``Kconfig``, allora verificate che il kernel compili con diverse + configurazioni dove i simboli sono disabilitati e/o ``=m`` (se c'è la + possibilità) [non tutti contemporaneamente, solo diverse combinazioni + casuali]: + + ``CONFIG_SMP``, ``CONFIG_SYSFS``, ``CONFIG_PROC_FS``, ``CONFIG_INPUT``, + ``CONFIG_PCI``, ``CONFIG_BLOCK``, ``CONFIG_PM``, ``CONFIG_MAGIC_SYSRQ``, + ``CONFIG_NET``, ``CONFIG_INET=n`` (ma l'ultimo con ``CONFIG_NET=y``). |
