Merge branch 'bpf-link-support-for-tc-bpf-programs'
Daniel Borkmann says:
==================== BPF link support for tc BPF programs
This series adds BPF link support for tc BPF programs. We initially presented the motivation, related work and design at last year's LPC conference in the networking & BPF track [0], and a recent update on our progress of the rework during this year's LSF/MM/BPF summit [1]. The main changes are in first two patches and the last two have an extensive batch of test cases we developed along with it, please see individual patches for details. We tested this series with tc-testing selftest suite as well as BPF CI/selftests. Thanks!
v5 -> v6: - Remove export symbol on tcx_inc/dec (Jakub) - Treat fd==0 as invalid (Stan, Alexei) v4 -> v5: - Updated bpftool docs and usage of bpftool net (Quentin) - Consistent dump "prog id"/"link id" -> "prog_id"/"link_id" (Quentin) - Reworked bpftool flag output handling (Quentin) - LIBBPF_OPTS_RESET() macro with varargs for reinit (Andrii) - libbpf opts/link bail out on relative_fd && relative_id (Andrii) - libbpf improvements for assigning attr.relative_{id,fd} (Andrii) - libbpf sorting in libbpf.map (Andrii) - libbpf move ifindex to bpf_program__attach_tcx param (Andrii) - libbpf move BPF_F_ID flag handling to bpf_link_create (Andrii) - bpf_program_attach_fd with tcx instead of tc (Andrii) - Reworking kernel-internal bpf_mprog API (Alexei, Andrii) - Change "object" notation to "id_or_fd" (Andrii) - Remove on stack cpp[BPF_MPROG_MAX] and switch to memmove (Andrii) - Simplify bpf_mprog_{insert,delete} and add comment on internals - Get rid of BPF_MPROG_* return codes (Alexei, Andrii) v3 -> v4: - Fix bpftool output to display tcx/{ingress,egress} (Stan) - Documentation around API, BPF_MPROG_* return codes and locking expectations (Stan, Alexei) - Change _after and _before to have the same semantics for return value (Alexei) - Rework mprog initialization and move allocation/free one layer up into tcx to simplify the code (Stan) - Add comment on synchronize_rcu and parent->ref (Stan) - Add comment on bpf_mprog_pos_() helpers wrt target position (Stan) v2 -> v3: - Removal of BPF_F_FIRST/BPF_F_LAST from control UAPI (Toke, Stan) - Along with that full rework of bpf_mprog internals to simplify dependency management, looks much nicer now imho - Just single bpf_mprog_cp instead of two (Andrii) - atomic64_t for revision counter (Andrii) - Evaluate target position and reject on conflicts (Andrii) - Keep track of actual count in bpf_mprob_bundle (Andrii) - Make combo of REPLACE and BEFORE/AFTER work (Andrii) - Moved miniq as first struct member (Jamal) - Rework tcx_link_attach with regards to rtnl (Jakub, Andrii) - Moved wrappers after bpf_prog_detach_ops (Andrii) - Removed union for relative_fd and friends for opts and link in libbpf (Andrii) - Add doc comments to attach/detach/query libbpf APIs (Andrii) - Dropped SEC_ATTACHABLE_OPT (Andrii) - Add an OPTS_ZEROED check to bpf_link_create (Andrii) - Keep opts as the last argument in bpf_program_attach_fd (Andrii) - Rework bpf_program_attach_fd (Andrii) - Remove OPTS_GET before we checked OPTS_VALID in bpf_program__attach_tcx (Andrii) - Add `size_t :0;` to prevent compiler from leaving garbage (Andrii) - Add helper macro to clear opts structs which I found useful when writing tests - Rework of both opts and link test cases to accommodate for changes v1 -> v2: - Rework of almost entire series to remove prio from UAPI and switch to better control directives BPF_F_FIRST/BPF_F_LAST/BPF_F_BEFORE/ BPF_F_AFTER (Alexei, Toke, Stan, Andrii) - Addition of big test suite to cover all corner cases

bpftool: Extend net dump with tcx progs
Add support to dump fd-based attach types via bpftool. This includes both the tc BPF link and attach ops programs. Dumped information contain the attach location, function entry name, program ID and link ID when applicable.
Example with tc BPF link:
# ./bpftool net xdp:
tc: bond0(4) tcx/ingress cil_from_netdev prog_id 784 link_id 10 bond0(4) tcx/egress cil_to_netdev prog_id 804 link_id 11

netfilter:
Example with tc BPF attach ops:
# ./bpftool net xdp:
tc: bond0(4) tcx/ingress cil_from_netdev prog_id 654 bond0(4) tcx/egress cil_to_netdev prog_id 672
flow_dissector:
netfilter:
Currently, permanent flags are not yet supported, so 'unknown' ones are dumped via NET_DUMP_UINT_ONLY() and once we do have permanent ones, we dump them as human readable string.

Pull networking updates from Jakub Kicinski: "Core ----
- Defer freeing TCP skbs to the BH handler, whenever possible, or at least perform the freeing outside of the socket lock section to decrease cross-CPU allocator work and improve latency.
- Add netdevice refcount tracking to locate sources of netdevice and net namespace refcount leaks.
- Make Tx watchdog less intrusive - avoid pausing Tx and restarting all queues from a single CPU removing latency spikes.
- Various small optimizations throughout the stack from Eric Dumazet.
- Make netdev->dev_addr[] constant, force modifications to go via appropriate helpers to allow us to keep addresses in ordered data structures.
- Replace unix_table_lock with per-hash locks, improving performance of bind() calls.
- Extend skb drop tracepoint with a drop reason.
- Allow SO_MARK and SO_PRIORITY setsockopt under CAP_NET_RAW.
BPF ---
- New helpers: - bpf_find_vma(), find and inspect VMAs for profiling use cases - bpf_loop(), runtime-bounded loop helper trading some execution time for much faster (if at all converging) verification - bpf_strncmp(), improve performance, avoid compiler flakiness - bpf_get_func_arg(), bpf_get_func_ret(), bpf_get_func_arg_cnt() for tracing programs, all inlined by the verifier
- Support BPF relocations (CO-RE) in the kernel loader.
- Further the support for BTF_TYPE_TAG annotations.
- Allow access to local storage in sleepable helpers.
- Convert verifier argument types to a composable form with different attributes which can be shared across types (ro, maybe-null).
- Prepare libbpf for upcoming v1.0 release by cleaning up APIs, creating new, extensible ones where missing and deprecating those to be removed.
Protocols ---------
- WiFi (mac80211/cfg80211): - notify user space about long "come back in N" AP responses, allow it to react to such temporary rejections - allow non-standard VHT MCS 10/11 rates - use coarse time in airtime fairness code to save CPU cycles
- Bluetooth: - rework of HCI command execution serialization to use a common queue and work struct, and improve handling errors reported in the middle of a batch of commands - rework HCI event handling to use skb_pull_data, avoiding packet parsing pitfalls - support AOSP Bluetooth Quality Report
- SMC: - support net namespaces, following the RDMA model - improve connection establishment latency by pre-clearing buffers - introduce TCP ULP for automatic redirection to SMC
- Multi-Path TCP: - support ioctls: SIOCINQ, OUTQ, and OUTQNSD - support socket options: IP_TOS, IP_FREEBIND, IP_TRANSPARENT, IPV6_FREEBIND, and IPV6_TRANSPARENT, TCP_CORK and TCP_NODELAY - support cmsgs: TCP_INQ - improvements in the data scheduler (assigning data to subflows) - support fastclose option (quick shutdown of the full MPTCP connection, similar to TCP RST in regular TCP)
- MCTP (Management Component Transport) over serial, as defined by DMTF spec DSP0253 - "MCTP Serial Transport Binding".
Driver API ----------
- Support timestamping on bond interfaces in active/passive mode.
- Introduce generic phylink link mode validation for drivers which don't have any quirks and where MAC capability bits fully express what's supported. Allow PCS layer to participate in the validation. Convert a number of drivers.
- Add support to set/get size of buffers on the Rx rings and size of the tx copybreak buffer via ethtool.
- Support offloading TC actions as first-class citizens rather than only as attributes of filters, improve sharing and device resource utilization.
- WiFi (mac80211/cfg80211): - support forwarding offload (ndo_fill_forward_path) - support for background radar detection hardware - SA Query Procedures offload on the AP side
New hardware / drivers ----------------------
- tsnep - FPGA based TSN endpoint Ethernet MAC used in PLCs with real-time requirements for isochronous communication with protocols like OPC UA Pub/Sub.
- Qualcomm BAM-DMUX WWAN - driver for data channels of modems integrated into many older Qualcomm SoCs, e.g. MSM8916 or MSM8974 (qcom_bam_dmux).

bpftool: Update doc (use susbtitutions) and test_bpftool_synctypes.py
test_bpftool_synctypes.py helps detecting inconsistencies in bpftool between the different list of types and options scattered in the sources, the documentation, and the bash completion. For options that apply to all bpftool commands, the script had a hardcoded list of values, and would use them to check whether the man pages are up-to-date. When writing the script, it felt acceptable to have this list in order to avoid to open and parse bpftool's main.h every time, and because the list of global options in bpftool doesn't change so often.
However, this is prone to omissions, and we recently added a new -l|--legacy option which was described in common_options.rst, but not listed in the options summary of each manual page. The script did not complain, because it keeps comparing the hardcoded list to the (now) outdated list in the header file.
To address the issue, this commit brings the following changes:
- Options that are common to all bpftool commands (--json, --pretty, and --debug) are moved to a dedicated file, and used in the definition of a RST substitution. This substitution is used in the sources of all the man pages.
- This list of common options is updated, with the addition of the new -l|--legacy option.
- The script test_bpftool_synctypes.py is updated to compare: - Options specific to a command, found in C files, for the interactive help messages, with the same specific options from the relevant man page for that command. - Common options, checked just once: the list in main.h is compared with the new list in substitutions.rst.

bpftool: Add SPDX tags to RST documentation files
Most files in the kernel repository have a SPDX tags. The files that don't have such a tag (or another license boilerplate) tend to fall under the GPL-2.0 license. In the past, bpftool's Makefile (for example) has been marked as GPL-2.0 for that reason, when in fact all bpftool is dual-licensed.
To prevent a similar confusion from happening with the RST documentation files for bpftool, let's explicitly mark all files as dual-licensed.

We've added 72 non-merge commits during the last 13 day(s) which contain a total of 171 files changed, 2728 insertions(+), 1143 deletions(-).
The main changes are:
1) Add btf_type_tag attributes to bring kernel annotations like __user/__rcu to BTF such that BPF verifier will be able to detect misuse, from Yonghong Song.
2) Big batch of libbpf improvements including various fixes, future proofing APIs, and adding a unified, OPTS-based bpf_prog_load() low-level API, from Andrii Nakryiko.
3) Add ingress_ifindex to BPF_SK_LOOKUP program type for selectively applying the programmable socket lookup logic to packets from a given netdev, from Mark Pashmfouroush.
4) Remove the 128M upper JIT limit for BPF programs on arm64 and add selftest to ensure exception handling still works, from Russell King and Alan Maguire.
5) Add a new bpf_find_vma() helper for tracing to map an address to the backing file such as shared library, from Song Liu.
6) Batch of various misc fixes to bpftool, fixing a memory leak in BPF program dump, updating documentation and bash-completion among others, from Quentin Monnet.
7) Deprecate libbpf bpf_program__get_prog_info_linear() API and migrate its users as the API is heavily tailored around perf and is non-generic, from Dave Marchevsky.
8) Enable libbpf's strict mode by default in bpftool and add a --legacy option as an opt-out for more relaxed BPF program requirements, from Stanislav Fomichev.
9) Fix bpftool to use libbpf_get_error() to check for errors, from Hengqi Chen.
