2021-12-01net: dsa: mv88e6xxx: Link in pcs_get_state() if AN is bypassedMarek Behún
Function mv88e6xxx_serdes_pcs_get_state() currently does not report link up if AN is enabled, Link bit is set, but Speed and Duplex Resolved bit is not set, which testing shows is the case for when auto-negotiation was bypassed (we have AN enabled but link partner does not). An example of such link partner is Marvell 88X3310 PHY, when put into the mode where host interface changes between 10gbase-r, 5gbase-r, 2500base-x and sgmii according to copper speed. The 88X3310 does not enable AN in 2500base-x, and so SerDes on mv88e6xxx currently does not link with it. Fix this.

2021-12-01net: dsa: mv88e6xxx: Fix inband AN for 2500base-x on 88E6393X familyMarek Behún
Inband AN is broken on Amethyst in 2500base-x mode when set by standard mechanism (via cmode). (There probably is some weird setting done by default in the switch for this mode that make it cycle in some state or something, because when the peer is the mvneta controller, it receives link change interrupts every ~0.3ms, but the link is always down.) Get around this by configuring the PCS mode to 1000base-x (where inband AN works), and then changing the SerDes frequency while SerDes transmitter and receiver are disabled, before enabling SerDes PHY. After disabling SerDes PHY, change the PCS mode back to 2500base-x, to avoid confusing the device (if we leave it at 1000base-x PCS mode but with different frequency, and then change cmode to sgmii, the device won't change the frequency because it thinks it already has the correct one). The register which changes the frequency is undocumented. I discovered it by going through all registers in the ranges 4.f000-4.f100 and 1e.8000-1e.8200 for all SerDes cmodes (sgmii, 1000base-x, 2500base-x, 5gbase-r, 10gbase-r, usxgmii) and filtering out registers that didn't make sense (the value was the same for modes which have different frequency). The result of this was: reg sgmii 1000base-x 2500base-x 5gbase-r 10gbase-r usxgmii 04.f002 005b 0058 0059 005c 005d 005f 04.f076 3000 0000 1000 4000 5000 7000 04.f07c 0950 0950 1850 0550 0150 0150 1e.8000 0059 0059 0058 0055 0051 0051 1e.8140 0e20 0e20 0e28 0e21 0e42 0e42 Register 04.f002 is the documented Port Operational Confiuration register, it's last 3 bits select PCS type, so changing this register also changes the frequency to the appropriate value. Registers 04.f076 and 04.f07c are not writable. Undocumented register 1e.8000 was the one: changing bits 3:0 from 9 to 8 changed SerDes frequency to 3.125 GHz, while leaving the value of PCS mode in register 04.f002.2:0 at 1000base-x. Inband autonegotiation started working correctly. (I didn't try anything with register 1e.8140 since 1e.8000 solved the problem.) Since I don't have documentation for this register 1e.8000.3:0, I am using the constants without names, but my hypothesis is that this register selects PHY frequency. If in the future I have access to an oscilloscope able to handle these frequencies, I will try to test this hypothesis.

Always use MLX5_FLOW_TABLE_OTHER_VPORT flag when creating egress ACL table for single FDB. Not doing so on BlueField will make firmware fail the command.

2021-11-30net/mlx5e: Sync TIR params updates against concurrent create/modifyTariq Toukan
Transport Interface Receive (TIR) objects perform the packet processing and reassembly and is also responsible for demultiplexing the packets into the different RQs. There are certain TIR context attributes that propagate to the pointed RQs and applied to them (like packet_merge offloads (LRO/SHAMPO) and tunneled_offload_en). When TIRs do not agree on attributes values, a "last one wins" policy is applied. Hence, if not synced properly, a race between TIR params update and a concurrent TIR create/modify operation might yield to a mismatch between the shadow parameters in SW and the actual applied state of the RQs in HW. tunneled_offload_en is a fixed attribute per profile, while packet merge offload state might be toggled and get out-of-sync. When this happens, packet_merge offload might be working although not requested, or the opposite. All updates to packet_merge state and all create/modify operations of regular redirection/steering TIRs are done under the same priv->state_lock, so they do not run in parallel, and no race is possible. However, there are other kind of TIRs (acceleration offloads TIRs, like TLS TIRs) which are created on demand for each new connection without holding the coarse priv->state_lock, hence might race. Fix this by synchronizing all packet_merge state reads and writes against all TIR create/modify operations. Include the modify operations of the regular redirection steering TIRs under the new lock, for better code layering and division of responsibilities.

2021-11-30igc: enable XDP metadata in driverJesper Dangaard Brouer
Enabling the XDP bpf_prog access to data_meta area is a very small change. Hint passing 'true' to xdp_prepare_buff(). The SKB layers can also access data_meta area, which required more driver changes to support. Reviewers, notice the igc driver have two different functions that can create SKBs, depending on driver config.

2021-11-30igc: AF_XDP zero-copy metadata adjust breaks SKBs on XDP_PASSJesper Dangaard Brouer
Driver already implicitly supports XDP metadata access in AF_XDP zero-copy mode, as xsk_buff_pool's xp_alloc() naturally set xdp_buff data_meta equal data. This works fine for XDP and AF_XDP, but if a BPF-prog adjust via bpf_xdp_adjust_meta() and choose to call XDP_PASS, then igc function igc_construct_skb_zc() will construct an invalid SKB packet. The function correctly include the xdp->data_meta area in the memcpy, but forgot to pull header to take metasize into account.

2021-11-30bond: pass get_ts_info and SIOC[SG]HWTSTAMP ioctl to active deviceHangbin Liu
We have VLAN PTP support(via get_ts_info) on kernel, and bond support(by getting active interface via netlink message) on userspace tool linuxptp. But there are always some users who want to use PTP with VLAN over bond, which is not able to do with the current implementation. This patch passed get_ts_info and SIOC[SG]HWTSTAMP ioctl to active device with bond mode active-backup/tlb/alb. With this users could get kernel native bond or VLAN over bond PTP support. Test with ptp4l and it works with VLAN over bond after this patch: ]# ptp4l -m -i bond0.23 ptp4l[53377.141]: selected /dev/ptp4 as PTP clock ptp4l[53377.142]: port 1: INITIALIZING to LISTENING on INIT_COMPLETE ptp4l[53377.143]: port 0: INITIALIZING to LISTENING on INIT_COMPLETE ptp4l[53377.143]: port 0: INITIALIZING to LISTENING on INIT_COMPLETE ptp4l[53384.127]: port 1: LISTENING to MASTER on ANNOUNCE_RECEIPT_TIMEOUT_EXPIRES ptp4l[53384.127]: selected local clock e41d2d.fffe.123db0 as best master ptp4l[53384.127]: port 1: assuming the grand master role Signed-off-by: Hangbin Liu <liuhangbin@gmail.com> Signed-off-by: David S.
