Core ---- - Introduce a config option to tweak MAX_SKB_FRAGS. Increasing the default value allows for better BIG TCP performances. - Reduce compound page head access for zero-copy data transfers. - RPS/RFS improvements, avoiding unneeded NET_RX_SOFTIRQ when possible. - Threaded NAPI improvements, adding defer skb free support and unneeded softirq avoidance. - Address dst_entry reference count scalability issues, via false sharing avoidance and optimize refcount tracking. - Add lockless accesses annotation to sk_err[_soft]. - Optimize again the skb struct layout. - Extends the skb drop reasons to make it usable by multiple subsystems. - Better const qualifier awareness for socket casts. BPF --- - Add skb and XDP typed dynptrs which allow BPF programs for more ergonomic and less brittle iteration through data and variable-sized accesses. - Add a new BPF netfilter program type and minimal support to hook BPF programs to netfilter hooks such as prerouting or forward. - Add more precise memory usage reporting for all BPF map types. - Adds support for using {FOU,GUE} encap with an ipip device operating in collect_md mode and add a set of BPF kfuncs for controlling encap params. - Allow BPF programs to detect at load time whether a particular kfunc exists or not, and also add support for this in light skeleton. - Bigger batch of BPF verifier improvements to prepare for upcoming BPF open-coded iterators allowing for less restrictive looping capabilities. - Rework RCU enforcement in the verifier, add kptr_rcu and enforce BPF programs to NULL-check before passing such pointers into kfunc. - Add support for kptrs in percpu hashmaps, percpu LRU hashmaps and in local storage maps. - Enable RCU semantics for task BPF kptrs and allow referenced kptr tasks to be stored in BPF maps. - Add support for refcounted local kptrs to the verifier for allowing shared ownership, useful for adding a node to both the BPF list and rbtree. - Add BPF verifier support for ST instructions in convert_ctx_access() which will help new -mcpu=v4 clang flag to start emitting them. - Add ARM32 USDT support to libbpf. - Improve bpftool's visual program dump which produces the control flow graph in a DOT format by adding C source inline annotations. Protocols --------- - IPv4: Allow adding to IPv4 address a 'protocol' tag. Such value indicates the provenance of the IP address. - IPv6: optimize route lookup, dropping unneeded R/W lock acquisition. - Add the handshake upcall mechanism, allowing the user-space to implement generic TLS handshake on kernel's behalf. - Bridge: support per-{Port, VLAN} neighbor suppression, increasing resilience to nodes failures. - SCTP: add support for Fair Capacity and Weighted Fair Queueing schedulers. - MPTCP: delay first subflow allocation up to its first usage. This will allow for later better LSM interaction. - xfrm: Remove inner/outer modes from input/output path. These are not needed anymore. - WiFi: - reduced neighbor report (RNR) handling for AP mode - HW timestamping support - support for randomized auth/deauth TA for PASN privacy - per-link debugfs for multi-link - TC offload support for mac80211 drivers - mac80211 mesh fast-xmit and fast-rx support - enable Wi-Fi 7 (EHT) mesh support Netfilter --------- - Add nf_tables 'brouting' support, to force a packet to be routed instead of being bridged. - Update bridge netfilter and ovs conntrack helpers to handle IPv6 Jumbo packets properly, i.e. fetch the packet length from hop-by-hop extension header. This is needed for BIT TCP support. - The iptables 32bit compat interface isn't compiled in by default anymore. - Move ip(6)tables builtin icmp matches to the udptcp one. This has the advantage that icmp/icmpv6 match doesn't load the iptables/ip6tables modules anymore when iptables-nft is used. - Extended netlink error report for netdevice in flowtables and netdev/chains. Allow for incrementally add/delete devices to netdev basechain. Allow to create netdev chain without device. Driver API ---------- - Remove redundant Device Control Error Reporting Enable, as PCI core has already error reporting enabled at enumeration time. - Move Multicast DB netlink handlers to core, allowing devices other then bridge to use them. - Allow the page_pool to directly recycle the pages from safely localized NAPI. - Implement lockless TX queue stop/wake combo macros, allowing for further code de-duplication and sanitization. - Add YNL support for user headers and struct attrs. - Add partial YNL specification for devlink. - Add partial YNL specification for ethtool. - Add tc-mqprio and tc-taprio support for preemptible traffic classes. - Add tx push buf len param to ethtool, specifies the maximum number of bytes of a transmitted packet a driver can push directly to the underlying device. - Add basic LED support for switch/phy. - Add NAPI documentation, stop relaying on external links. - Convert dsa_master_ioctl() to netdev notifier. This is a preparatory work to make the hardware timestamping layer selectable by user space. - Add transceiver support and improve the error messages for CAN-FD controllers.

|
|
* "GPL" [GNU Public License v2]
|
|
* "GPL v2" [GNU Public License v2]
|

* "GPL and additional rights" [GNU Public License v2 rights and more]

* "Dual MIT/GPL" [GNU Public License v2

|
|
* "Dual MPL/GPL" [GNU Public License v2
|
|
* or Mozilla license choice]
|
|
*
|
|
* The following other idents are available
|
|
*
|
|
* "Proprietary" [Non free products]
|
|
*
|
|
* Both "GPL v2" and "GPL" (the latter also in dual licensed strings) are
|
|
* merely stating that the module is licensed under the GPL v2, but are not
|
|
* telling whether "GPL v2 only" or "GPL v2 or later". The reason why there
|
|
* are two variants is a historic and failed attempt to convey more
|
|
* information in the MODULE_LICENSE string. For module loading the
|
|
* "only/or later" distinction is completely irrelevant and does neither
|
|
* replace the proper license identifiers in the corresponding source file
|
|
* nor amends them in any way. The sole purpose is to make the
|
|
* 'Proprietary' flagging work and to refuse to bind symbols which are
|
|
* exported with EXPORT_SYMBOL_GPL when a non free module is loaded.
|
|
*
|
|
* In the same way "BSD" is not a clear license information. It merely
|
|
* states, that the module is licensed under one of the compatible BSD
|
|
* license variants. The detailed and correct license information is again
|
|
* to be found in the corresponding source files.
|
|
*
|
|
* There are dual licensed components, but when running with Linux it is the
|
|
* GPL that is relevant so this is a non issue. Similarly LGPL linked with GPL
|
|
* is a GPL combined work.
|
|
*
|
|
* This exists for several reasons
|
|
* 1. So modinfo can show license info for users wanting to vet their setup
|
|
* is free
|
|
* 2. So the community can ignore bug reports including proprietary modules
|
|
* 3. So vendors can do likewise based on their own policies
