The main changes are: 1) Add open-coded task, css_task and css iterator support. One of the use cases is customizable OOM victim selection via BPF, from Chuyi Zhou. 2) Fix BPF verifier's iterator convergence logic to use exact states comparison for convergence checks, from Eduard Zingerman, Andrii Nakryiko and Alexei Starovoitov. 3) Add BPF programmable net device where bpf_mprog defines the logic of its xmit routine. It can operate in L3 and L2 mode, from Daniel Borkmann and Nikolay Aleksandrov. 4) Batch of fixes for BPF per-CPU kptr and re-enable unit_size checking for global per-CPU allocator, from Hou Tao. 5) Fix libbpf which eagerly assumed that SHT_GNU_verdef ELF section was going to be present whenever a binary has SHT_GNU_versym section, from Andrii Nakryiko. 6) Fix BPF ringbuf correctness to fold smp_mb__before_atomic() into atomic_set_release(), from Paul E. McKenney. 7) Add a warning if NAPI callback missed xdp_do_flush() under CONFIG_DEBUG_NET which helps checking if drivers were missing the former, from Sebastian Andrzej Siewior. 8) Fix missed RCU read-lock in bpf_task_under_cgroup() which was throwing a warning under sleepable programs, from Yafang Shao. 9) Avoid unnecessary -EBUSY from htab_lock_bucket by disabling IRQ before checking map_locked, from Song Liu. 10) Make BPF CI linked_list failure test more robust, from Kumar Kartikeya Dwivedi. 11) Enable samples/bpf to be built as PIE in Fedora, from Viktor Malik. 12) Fix xsk starving when multiple xsk sockets were associated with a single xsk_buff_pool, from Albert Huang. 13) Clarify the signed modulo implementation for the BPF ISA standardization document that it uses truncated division, from Dave Thaler. 14) Improve BPF verifier's JEQ/JNE branch taken logic to also consider signed bounds knowledge, from Andrii Nakryiko. 15) Add an option to XDP selftests to use multi-buffer AF_XDP xdp_hw_metadata and mark used XDP programs as capable to use frags, from Larysa Zaremba. 16) Fix bpftool's BTF dumper wrt printing a pointer value and another one to fix struct_ops dump in an array, from Manu Bretelle. * tag 'for-netdev' of ssh://gitolite.kernel.org/pub/scm/linux/kernel/git/bpf/bpf-next: (51 commits) netkit: Remove explicit active/peer ptr initialization selftests/bpf: Fix selftests broken by mitigations=off samples/bpf: Allow building with custom bpftool samples/bpf: Fix passing LDFLAGS to libbpf samples/bpf: Allow building with custom CFLAGS/LDFLAGS bpf: Add more WARN_ON_ONCE checks for mismatched alloc and free selftests/bpf: Add selftests for netkit selftests/bpf: Add netlink helper library bpftool: Extend net dump with netkit progs bpftool: Implement link show support for netkit libbpf: Add link-based API for netkit tools: Sync if_link uapi header netkit, bpf: Add bpf programmable net device bpf: Improve JEQ/JNE branch taken logic bpf: Fold smp_mb__before_atomic() into atomic_set_release() bpf: Fix unnecessary -EBUSY from htab_lock_bucket xsk: Avoid starving the xsk further down the list bpf: print full verifier states on infinite loop detection selftests/bpf: test if state loops are detected in a tricky case bpf: correct loop detection for iterators convergence ... ==================== Link: https://lore.kernel.org/r/20231026150509.2824-1-daniel@iogearbox.net Signed-off-by: Jakub Kicinski <kuba@kernel.org>
2023-10-26netlink: specs: support conditional operationsJakub Kicinski
Page pool code is compiled conditionally, but the operations are part of the shared netlink family. We can handle this by reporting empty list of pools or -EOPNOTSUPP / -ENOSYS but the cleanest way seems to be removing the ops completely at compilation time. That way user can see that the page pool ops are not present using genetlink introspection. Same way they'd check if the kernel is "new enough" to support the ops. Extend the specs with the ability to specify the config condition under which op (and its policies, etc.) should be hidden.

2023-10-25mptcp: add a new sysctl for make after break timeoutPaolo Abeni
The MPTCP protocol allows sockets with no alive subflows to stay in ESTABLISHED status for and user-defined timeout, to allow for later subflows creation. Currently such timeout is constant - TCP_TIMEWAIT_LEN. Let the user-space configure them via a newly added sysctl, to better cope with busy servers and simplify (make them faster) the relevant pktdrill tests. Note that the new know does not apply to orphaned MPTCP socket waiting for the data_fin handshake completion: they always wait TCP_TIMEWAIT_LEN.

The Marvell MV88E6060 is one of the oldest DSA switches from Marvell, and it has DT bindings used in the wild. Let's define them properly. It is different enough from the rest of the MV88E6xxx switches that it deserves its own binding.

When adding a proper schema for the Marvell mx88e6xxx switch, the scripts start complaining about this embedded example: dtschema/dtc warnings/errors: net/marvell,mvusb.example.dtb: switch@0: ports: '#address-cells' is a required property from schema $id: http://devicetree.org/schemas/net/dsa/marvell,mv88e6xxx.yaml# net/marvell,mvusb.example.dtb: switch@0: ports: '#size-cells' is a required property from schema $id: http://devicetree.org/schemas/net/dsa/marvell,mv88e6xxx.yaml# Fix this up by extending the example with those properties in the ports node. While we are at it, rename "ports" to "ethernet-ports" and rename "switch" to "ethernet-switch" as this is recommended practice.

Declaration is '.. c:function:: void ieee80211_tx_status (struct ieee80211_hw *hw, struct sk_buff *skb)'. This is because there's a function named ieee80211_tx_status() and a struct named ieee80211_tx_status. This has been discussed previously but no solution found: https://lore.kernel.org/all/20220521114629.6ee9fc06@coco.lan/ There's also a bug open for three years with no solution in sight: https://github.com/sphinx-doc/sphinx/pull/8313 So I guess we have no other solution than to a workaround this in the code, for example to rename the function to ieee80211_tx_status_skb() to avoid the name conflict. I got the idea for the name from ieee80211_tx_status_noskb() in which the skb is not provided as an argument, instead with ieee80211_tx_status_skb() the skb is provided. Compile tested only.

2023-10-20netlink: add variable-length / auto integersJakub Kicinski
We currently push everyone to use padding to align 64b values in netlink. Un-padded nla_put_u64() doesn't even exist any more. The story behind this possibly start with this thread: https://lore.kernel.org/netdev/20121204.130914.1457976839967676240.davem@davemloft.net/ where DaveM was concerned about the alignment of a structure containing 64b stats. If user space tries to access such struct directly: struct some_stats *stats = nla_data(attr); printf("A: %llu", stats->a); lack of alignment may become problematic for some architectures. These days we most often put every single member in a separate attribute, meaning that the code above would use a helper like nla_get_u64(), which can deal with alignment internally. Even for arches which don't have good unaligned access - access aligned to 4B should be pretty efficient. Kernel and well known libraries deal with unaligned input already. Padded 64b is quite space-inefficient (64b + pad means at worst 16B per attr vs 32b which takes 8B). It is also more typing: if (nla_put_u64_pad(rsp, NETDEV_A_SOMETHING_SOMETHING, value, NETDEV_A_SOMETHING_PAD)) Create a new attribute type which will use 32 bits at netlink level if value is small enough (probably most of the time?), and (4B-aligned) 64 bits otherwise. Kernel API is just: if (nla_put_uint(rsp, NETDEV_A_SOMETHING_SOMETHING, value)) Calling this new type "just" sint / uint with no specific size will hopefully also make people more comfortable with using it. Currently telling people "don't use u8, you may need the bits, and netlink will round up to 4B, anyway" is the #1 comment we give to newcomers. In terms of netlink layout it looks like this: 0 4 8 12 16 32b: [nlattr][ u32 ] 64b: [ pad ][nlattr][ u64 ] uint(32) [nlattr][ u32 ] uint(64) [nlattr][ u64 ] Signed-off-by: Jakub Kicinski <kuba@kernel.org> Acked-by: Nicolas Dichtel <nicolas.dichtel@6wind.com> Signed-off-by: David S.

Extend the support to full range of min/max checks. None of the existing YNL families required complex integer validation. The support is less than trivial, because we try to keep struct nla_policy tiny the min/max members it holds in place are s16. Meaning we can only express checks in range of s16.

Accordingly, FW sends vhca event to driver to inform about this state change asynchronously. Each vhca event is critical because all related SW/FW operations are triggered by it. Currently there is only a single mlx5 general event handler which not only handles vhca event but many other events. This incurs huge bottleneck because all events are forced to be handled in serial manner. Moreover, all SFs share same table_lock which inevitably impacts each other when they are created in parallel. This series will solve this issue by: 1. A dedicated vhca event handler is introduced to eliminate the mutual impact with other mlx5 events. 2. Max FW threads work queues are employed in the vhca event handler to fully utilize FW capability. 3. Redesign SF active work logic to completely remove table_lock. With above optimization, SF creation time is reduced by 25%, i.e. from 80s to 60s when creating 100 SFs. Patches summary: Patch 1 - implement dedicated vhca event handler with max FW cmd threads of work queues.
