Merge branch 'New nf_conntrack kfuncs for insertion, changing timeout, status'

Kumar Kartikeya Dwivedi says:

====================

Introduce the following new kfuncs:
- bpf_{xdp,skb}_ct_alloc
- bpf_ct_insert_entry
- bpf_ct_{set,change}_timeout
- bpf_ct_{set,change}_status

The setting of timeout and status on allocated or inserted/looked up CT
is same as the ctnetlink interface, hence code is refactored and shared
with the kfuncs. It is ensured allocated CT cannot be passed to kfuncs
that expected inserted CT, and vice versa. Please see individual patches
for details.

bpf: Introduce 8-byte BTF set

Introduce support for defining flags for kfuncs using a new set of
macros, BTF_SET8_START/BTF_SET8_END, which define a set which contains
8 byte elements (each of which consists of a pair of BTF ID and flags),
using a new BTF_ID_FLAGS macro.

This will be used to tag kfuncs registered for a certain program type
as acquire, release, sleepable, ret_null, etc. without having to create
more and more sets which was proving to be an unscalable solution.

Now, when looking up whether a kfunc is allowed for a certain program,
we can also obtain its kfunc flags in the same call and avoid further
lookups.

The resolve_btfids change is split into a separate patch.

Merge branch 'bpf: cgroup_sock lsm flavor'

Stanislav Fomichev says:

====================

This series implements new lsm flavor for attaching per-cgroup programs to
existing lsm hooks. The cgroup is taken out of 'current', unless
the first argument of the hook is 'struct socket'. In this case,
the cgroup association is taken out of socket. The attachment
looks like a regular per-cgroup attachment: we add new BPF_LSM_CGROUP
attach type which, together with attach_btf_id, signals per-cgroup lsm.
Behind the scenes, we allocate trampoline shim program and
attach to lsm. This program looks up cgroup from current/socket
and runs cgroup's effective prog array. The rest of the per-cgroup BPF
stays the same: hierarchy, local storage, retval conventions
(return 1 == success).

Current limitations:
* haven't considered sleepable bpf; can be extended later on
* not sure the verifier does the right thing with null checks;
see latest selftest for details
* total of 10 (global) per-cgroup LSM attach points

v11:
- Martin: address selftest memory & fd leaks
- Martin: address moving into root (instead have another temp leaf cgroup)

- Martin: update tools header in a separate commit
- Quentin: do libbpf_find_kernel_btf from the ops that need it
- lkp@intel.com: another build failure

v9:
Major change since last version is the switch to bpf_setsockopt to
change the socket state instead of letting the progs poke socket directly.
This, in turn, highlights the challenge that we need to care about whether
the socket is locked or not when we call bpf_setsockopt. (with my original
example selftest, the hooks are running early in the init phase for this
not to matter).

For now, I've added two btf id lists:
* hooks where we know the socket is locked and it's safe to call bpf_setsockopt
* hooks where we know the socket is _not_ locked, but the hook works on
the socket that's not yet exposed to userspace so it should be safe
(for this mode, special new set of bpf_{s,g}etsockopt helpers
is added; they don't have sock_owned_by_me check)

Going forward, for the rest of the hooks, this might be a good motivation
to expand lsm cgroup to support sleeping bpf and allow the callers to
lock/unlock sockets or have a new bpf_setsockopt variant that does the
locking.

- ifdef around cleanup in cgroup_bpf_release
- Andrii: a few nits in libbpf patches
- Martin: remove unused btf_id_set_index
- Martin: bring back refcnt for cgroup_atype
- Martin: make __cgroup_bpf_query a bit more readable
- Martin: expose dst_prog->aux->attach_btf as attach_btf_obj_id as well
- Martin: reorg check_return_code path for BPF_LSM_CGROUP
- Martin: return directly from check_helper_call (instead of goto err)
- Martin: add note to new warning in check_return_code, print only for void hooks
- Martin: remove confusing shim reuse
- Martin: use bpf_{s,g}etsockopt instead of poking into socket data
- Martin: use CONFIG_CGROUP_BPF in bpf_prog_alloc_no_stats/bpf_prog_free_deferred

- Andrii: reorder SEC_DEF("lsm_cgroup+")
- Andrii: OPTS_SET instead of OPTS_HAS
- Andrii: rename attach_btf_func_id
- Andrii: move into 1.0 map

v7:
- there were a lot of comments last time, hope I didn't forget anything,
some of the bigger ones:
- Martin: use/extend BTF_SOCK_TYPE_SOCKET
- Martin: expose bpf_set_retval
- Martin: reject 'return 0' at the verifier for 'void' hooks
- Martin: prog_query returns all BPF_LSM_CGROUP, prog_info
returns attach_btf_func_id
- Andrii: split libbpf changes
- Andrii: add field access test to test_progs, not test_verifier (still
using asm though)
- things that I haven't addressed, stating them here explicitly, let
me know if some of these are still problematic:
1. Andrii: exposing only link-based api: seems like the changes
to support non-link-based ones are minimal, couple of lines,
so seems like it worth having it?
2. Alexei: applying cgroup_atype for all cgroup hooks, not only
cgroup lsm: looks a bit harder to apply everywhere that I
originally thought; with lsm cgroup, we have a shim_prog pointer where
we store cgroup_atype; for non-lsm programs, we don't have a
trace program where to store it, so we still need some kind
of global table to map from "static" hook to "dynamic" slot.
So I'm dropping this "can be easily extended" clause from the
description for now. I have converted this whole machinery
to an RCU-managed list to remove synchronize_rcu().
- also note that I had to introduce new bpf_shim_tramp_link and
moved refcnt there; we need something to manage new bpf_tramp_link

v6:
- remove active count & stats for shim program (Martin KaFai Lau)
- remove NULL/error check for btf_vmlinux (Martin)

bpf: per-cgroup lsm flavor

Allow attaching to lsm hooks in the cgroup context.

Attaching to per-cgroup LSM works exactly like attaching
to other per-cgroup hooks. New BPF_LSM_CGROUP is added
to trigger new mode; the actual lsm hook we attach to is
signaled via existing attach_btf_id.

For the hooks that have 'struct socket' or 'struct sock' as its first
argument, we use the cgroup associated with that socket. For the rest,
we use 'current' cgroup (this is all on default hierarchy == v2 only).
Note that for some hooks that work on 'struct sock' we still
take the cgroup from 'current' because some of them work on the socket
that hasn't been properly initialized yet.

Behind the scenes, we allocate a shim program that is attached
to the trampoline and runs cgroup effective BPF programs array.
This shim has some rudimentary ref counting and can be shared
between several programs attaching to the same lsm hook from
different cgroups.

Note that this patch bloats cgroup size because we add 211
cgroup_bpf_attach_type(s) for simplicity sake. This will be
addressed in the subsequent patch.

Also note that we only add non-sleepable flavor for now. To enable
sleepable use-cases, bpf_prog_run_array_cg has to grab trace rcu,
shim programs have to be freed via trace rcu, cgroup_bpf.effective
should be also trace-rcu-managed + maybe some other changes that
I'm not aware of.

Merge tag 'net-next-5.19' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next

Pull networking updates from Jakub Kicinski:
"Core
----

- Support TCPv6 segmentation offload with super-segments larger than
64k bytes using the IPv6 Jumbogram extension header (AKA BIG TCP).

- Generalize skb freeing deferral to per-cpu lists, instead of
per-socket lists.

- Add a netdev statistic for packets dropped due to L2 address
mismatch (rx_otherhost_dropped).

- Continue work annotating skb drop reasons.

- Accept alternative netdev names (ALT_IFNAME) in more netlink
requests.

- Add VLAN support for AF_PACKET SOCK_RAW GSO.

- Allow receiving skb mark from the socket as a cmsg.

- Enable memcg accounting for veth queues, sysctl tables and IPv6.

BPF
---

- Add libbpf support for User Statically-Defined Tracing (USDTs).

- Speed up symbol resolution for kprobes multi-link attachments.

- Support storing typed pointers to referenced and unreferenced
objects in BPF maps.

- Add support for BPF link iterator.

- Introduce access to remote CPU map elements in BPF per-cpu map.

- Allow middle-of-the-road settings for the
kernel.unprivileged_bpf_disabled sysctl.

- Implement basic types of dynamic pointers e.g. to allow for
dynamically sized ringbuf reservations without extra memory copies.

Protocols
---------

- Retire port only listening_hash table, add a second bind table
hashed by port and address. Avoid linear list walk when binding to
very popular ports (e.g. 443).

- Add bridge FDB bulk flush filtering support allowing user space to
remove all FDB entries matching a condition.

- Introduce accept_unsolicited_na sysctl for IPv6 to implement
router-side changes for RFC9131.

- Support for MPTCP path manager in user space.

- Add MPTCP support for fallback to regular TCP for connections that
have never connected additional subflows or transmitted
out-of-sequence data (partial support for RFC8684 fallback).

- Avoid races in MPTCP-level window tracking, stabilize and improve
throughput.

- Support lockless operation of GRE tunnels with seq numbers enabled.

- WiFi support for host based BSS color collision detection.

- Add support for SO_TXTIME/SCM_TXTIME on CAN sockets.

- Support transmission w/o flow control in CAN ISOTP (ISO 15765-2).

- Support zero-copy Tx with TLS 1.2 crypto offload (sendfile).

- Allow matching on the number of VLAN tags via tc-flower.

- Add tracepoint for tcp_set_ca_state().

Driver API
----------

- Improve error reporting from classifier and action offload.

- Add support for listing line cards in switches (devlink).

- Add helpers for reporting page pool statistics with ethtool -S.

- Add support for reading clock cycles when using PTP virtual clocks,
instead of having the driver convert to time before reporting. This
makes it possible to report time from different vclocks.

- Support configuring low-latency Tx descriptor push via ethtool.

- Separate Clause 22 and Clause 45 MDIO accesses more explicitly.

Merge branch 'bpf: mptcp: Support for mptcp_sock'

Mat Martineau says:

====================

This patch set adds BPF access to mptcp_sock structures, along with
associated self tests. You may recognize some of the code from earlier
(https://lore.kernel.org/bpf/20200918121046.190240-6-nicolas.rybowski@tessares.net/)
but it has been reworked quite a bit.

v1 -> v2: Emit BTF type, add func_id checks in verifier.c and bpf_trace.c,
remove build check for CONFIG_BPF_JIT, add selftest check for CONFIG_MPTCP,
and add a patch to include CONFIG_IKCONFIG/CONFIG_IKCONFIG_PROC for the
BPF self tests.

v2 -> v3: Access sysctl through the filesystem to work around CI use of
the more limited busybox sysctl command.

v3 -> v4: Dropped special case kernel code for tcp_sock is_mptcp, use
existing bpf_tcp_helpers.h, and add check for 'ip mptcp monitor' support.

v4 -> v5: Use BPF test skeleton, more consistent use of ASSERT macros,
drop some unnecessary parameters / checks, and use tracing to acquire
MPTCP token.

Geliang Tang (6):
bpf: add bpf_skc_to_mptcp_sock_proto
selftests/bpf: Enable CONFIG_IKCONFIG_PROC in config
selftests/bpf: test bpf_skc_to_mptcp_sock
selftests/bpf: verify token of struct mptcp_sock
selftests/bpf: verify ca_name of struct mptcp_sock
