====================
pull-request: bpf-next 2024-05-13

We've added 119 non-merge commits during the last 14 day(s) which contain
a total of 134 files changed, 9462 insertions(+), 4742 deletions(-).

The main changes are:

1) Add BPF JIT support for 32-bit ARCv2 processors, from Shahab Vahedi.

2) Add BPF range computation improvements to the verifier in particular
   around XOR and OR operators, refactoring of checks for range computation
   and relaxing MUL range computation so that src_reg can also be an unknown
   scalar, from Cupertino Miranda.

3) Add support to attach kprobe BPF programs through kprobe_multi link in
   a session mode, meaning, a BPF program is attached to both function entry
   and return, the entry program can decide if the return program gets
   executed and the entry program can share u64 cookie value with return
   program. Session mode is a common use-case for tetragon and bpftrace,
   from Jiri Olsa.

4) Fix a potential overflow in libbpf's ring__consume_n() and improve libbpf
   as well as BPF selftest's struct_ops handling, from Andrii Nakryiko.

5) Improvements to BPF selftests in context of BPF gcc backend,
   from Jose E. Marchesi & David Faust.

6) Migrate remaining BPF selftest tests from test_sock_addr.c to prog_test-
   -style in order to retire the old test, run it in BPF CI and additionally
   expand test coverage, from Jordan Rife.

7) Big batch for BPF selftest refactoring in order to remove duplicate code
   around common network helpers, from Geliang Tang.

8) Another batch of improvements to BPF selftests to retire obsolete
   bpf_tcp_helpers.h as everything is available vmlinux.h,
   from Martin KaFai Lau.

9) Fix BPF map tear-down to not walk the map twice on free when both timer
   and wq is used, from Benjamin Tissoires.

10) Fix BPF verifier assumptions about socket->sk that it can be non-NULL,
    from Alexei Starovoitov.

11) Change BTF build scripts to using --btf_features for pahole v1.26+,
    from Alan Maguire.

12) Small improvements to BPF reusing struct_size() and krealloc_array(),
    from Andy Shevchenko.

13) Fix s390 JIT to emit a barrier for BPF_FETCH instructions,
    from Ilya Leoshkevich.

14) Extend TCP ->cong_control() callback in order to feed in ack and
    flag parameters and allow write-access to tp->snd_cwnd_stamp
    from BPF program, from Miao Xu.

15) Add support for internal-only per-CPU instructions to inline
    bpf_get_smp_processor_id() helper call for arm64 and riscv64 BPF JITs,
    from Puranjay Mohan.

16) Follow-up to remove the redundant ethtool.h from tooling infrastructure,
    from Tushar Vyavahare.

17) Extend libbpf to support "module:<function>" syntax for tracing
    programs, from Viktor Malik.

-/**
- * struct ethtool_cmd - DEPRECATED, link control and status
- * This structure is DEPRECATED, please use struct ethtool_link_settings.
- * @cmd: Command number = %ETHTOOL_GSET or %ETHTOOL_SSET
- * @supported: Bitmask of %SUPPORTED_* flags for the link modes,
- *	physical connectors and other link features for which the
- *	interface supports autonegotiation or auto-detection.
- *	Read-only.
- * @advertising: Bitmask of %ADVERTISED_* flags for the link modes,
- *	physical connectors and other link features that are
- *	advertised through autonegotiation or enabled for
- *	auto-detection.
- * @speed: Low bits of the speed, 1Mb units, 0 to INT_MAX or SPEED_UNKNOWN
- * @duplex: Duplex mode; one of %DUPLEX_*
- * @port: Physical connector type; one of %PORT_*
- * @phy_address: MDIO address of PHY (transceiver); 0 or 255 if not
- *	applicable.  For clause 45 PHYs this is the PRTAD.
- * @transceiver: Historically used to distinguish different possible
- *	PHY types, but not in a consistent way.  Deprecated.
- * @autoneg: Enable/disable autonegotiation and auto-detection;
- *	either %AUTONEG_DISABLE or %AUTONEG_ENABLE
- * @mdio_support: Bitmask of %ETH_MDIO_SUPPORTS_* flags for the MDIO
- *	protocols supported by the interface; 0 if unknown.
- *	Read-only.
- * @maxtxpkt: Historically used to report TX IRQ coalescing; now
- *	obsoleted by &struct ethtool_coalesce.  Read-only; deprecated.
- * @maxrxpkt: Historically used to report RX IRQ coalescing; now
- *	obsoleted by &struct ethtool_coalesce.  Read-only; deprecated.
- * @speed_hi: High bits of the speed, 1Mb units, 0 to INT_MAX or SPEED_UNKNOWN
- * @eth_tp_mdix: Ethernet twisted-pair MDI(-X) status; one of
- *	%ETH_TP_MDI_*.  If the status is unknown or not applicable, the
- *	value will be %ETH_TP_MDI_INVALID.  Read-only.
- * @eth_tp_mdix_ctrl: Ethernet twisted pair MDI(-X) control; one of
- *	%ETH_TP_MDI_*.  If MDI(-X) control is not implemented, reads
- *	yield %ETH_TP_MDI_INVALID and writes may be ignored or rejected.
- *	When written successfully, the link should be renegotiated if
- *	necessary.
- * @lp_advertising: Bitmask of %ADVERTISED_* flags for the link modes
- *	and other link features that the link partner advertised
- *	through autonegotiation; 0 if unknown or not applicable.
- *	Read-only.
- * @reserved: Reserved for future use; see the note on reserved space.
- *
- * The link speed in Mbps is split between @speed and @speed_hi.  Use
- * the ethtool_cmd_speed() and ethtool_cmd_speed_set() functions to
- * access it.
- *
- * If autonegotiation is disabled, the speed and @duplex represent the
- * fixed link mode and are writable if the driver supports multiple
- * link modes.  If it is enabled then they are read-only; if the link
- * is up they represent the negotiated link mode; if the link is down,
- * the speed is 0, %SPEED_UNKNOWN or the highest enabled speed and
- * @duplex is %DUPLEX_UNKNOWN or the best enabled duplex mode.
- *
- * Some hardware interfaces may have multiple PHYs and/or physical
- * connectors fitted or do not allow the driver to detect which are
- * fitted.  For these interfaces @port and/or @phy_address may be
- * writable, possibly dependent on @autoneg being %AUTONEG_DISABLE.
- * Otherwise, attempts to write different values may be ignored or
- * rejected.
- *
- * Users should assume that all fields not marked read-only are
- * writable and subject to validation by the driver.  They should use
- * %ETHTOOL_GSET to get the current values before making specific
- * changes and then applying them with %ETHTOOL_SSET.
- *
- * Deprecated fields should be ignored by both users and drivers.

- * drivers to improve latency under low packet rates and improve
- * throughput under high packet rates.  Some drivers only implement
- * one of RX or TX adaptive coalescing.  Anything not implemented by
- * the driver causes these values to be silently ignored.

- * @pkt_rate_low (both measured in packets per second) the
