has_vhe() expands to a compile-time constant when evaluated from the VHE or nVHE code, alternatively checking a static key when called from elsewhere in the kernel. On face value, this looks like a case of premature optimization, but in fact this allows symbol references on VHE-specific code paths to be dropped from the nVHE object. Expand the comment in has_vhe() to make this clearer, hopefully discouraging anybody from simplifying the code.

2022-06-08net: dsa: realtek: rtl8365mb: fix GMII caps for ports with internal PHYAlvin Šipraga1-29/+9
Since commit a18e6521a7d9 ("net: phylink: handle NA interface mode in phylink_fwnode_phy_connect()"), phylib defaults to GMII when no phy-mode or phy-connection-type property is specified in a DSA port node of the device tree. The same commit caused a regression in rtl8365mb whereby phylink would fail to connect, because the driver did not advertise support for GMII for ports with internal PHY. It should be noted that the aforementioned regression is not because the blamed commit was incorrect: on the contrary, the blamed commit is correcting the previous behaviour whereby unspecified phy-mode would cause the internal interface mode to be PHY_INTERFACE_MODE_NA. The rtl8365mb driver only worked by accident before because it _did_ advertise support for PHY_INTERFACE_MODE_NA, despite NA being reserved for internal use by phylink. With one mistake fixed, the other was exposed. Commit a5dba0f207e5 ("net: dsa: rtl8365mb: add GMII as user port mode") then introduced implicit support for GMII mode on ports with internal PHY to allow a PHY connection for device trees where the phy-mode is not explicitly set to "internal". At this point everything was working OK again. Subsequently, commit 6ff6064605e9 ("net: dsa: realtek: convert to phylink_generic_validate()") broke this behaviour again by discarding the usage of rtl8365mb_phy_mode_supported() - where this GMII support was indicated - while switching to the new .phylink_get_caps API. With the new API, rtl8365mb_phy_mode_supported() is no longer needed. Remove it altogether and add back the GMII capability - this time to rtl8365mb_phylink_get_caps() - so that the above default behaviour works for ports with internal PHY again.

Commit ede359d8843a ("net: dsa: mv88e6xxx: Link in pcs_get_state() if AN is bypassed") added the ability to link if AN was bypassed, and added filling of state->an_complete field, but set it to true if AN was enabled in BMCR, not when AN was reported complete in BMSR. This was done because for some reason, when I wanted to use BMSR value to infer an_complete, I was looking at BMSR_ANEGCAPABLE bit (which was always 1), instead of BMSR_ANEGCOMPLETE bit.

2022-06-08net: openvswitch: fix misuse of the cached connection on tuple changesIlya Maximets2-1/+9
If packet headers changed, the cached nfct is no longer relevant for the packet and attempt to re-use it leads to the incorrect packet classification. This issue is causing broken connectivity in OpenStack deployments with OVS/OVN due to hairpin traffic being unexpectedly dropped. The setup has datapath flows with several conntrack actions and tuple changes between them: actions:ct(commit,zone=8,mark=0/0x1,nat(src)), set(eth(src=00:00:00:00:00:01,dst=00:00:00:00:00:06)), set(ipv4(src=172.18.2.10,dst=192.168.100.6,ttl=62)), ct(zone=8),recirc(0x4) After the first ct() action the packet headers are almost fully re-written. The next ct() tries to re-use the existing nfct entry and marks the packet as invalid, so it gets dropped later in the pipeline. Clearing the cached conntrack entry whenever packet tuple is changed to avoid the issue. The flow key should not be cleared though, because we should still be able to match on the ct_state if the recirculation happens after the tuple change but before the next ct() action.

2022-06-08ip_gre: test csum_start instead of transport headerWillem de Bruijn1-6/+5
GRE with TUNNEL_CSUM will apply local checksum offload on CHECKSUM_PARTIAL packets. ipgre_xmit must validate csum_start after an optional skb_pull, else lco_csum may trigger an overflow. The original check was if (csum && skb_checksum_start(skb) < skb->data) return -EINVAL; This had false positives when skb_checksum_start is undefined: when ip_summed is not CHECKSUM_PARTIAL. A discussed refinement was straightforward if (csum && skb->ip_summed == CHECKSUM_PARTIAL && skb_checksum_start(skb) < skb->data) return -EINVAL; But was eventually revised more thoroughly: - restrict the check to the only branch where needed, in an uncommon GRE path that uses header_ops and calls skb_pull. - test skb_transport_header, which is set along with csum_start in skb_partial_csum_set in the normal header_ops datapath. Turns out skbs can arrive in this branch without the transport header set, e.g., through BPF redirection. Revise the check back to check csum_start directly, and only if CHECKSUM_PARTIAL. Do leave the check in the updated location. Check field regardless of whether TUNNEL_CSUM is configured.

2022-06-08net/mlx5e: CT: Fix cleanup of CT before cleanup of TC ct rulesPaul Blakey1-15/+16
CT cleanup assumes that all tc rules were deleted first, and so is free to delete the CT shared resources (e.g the dr_action fwd_action which is shared for all tuples). But currently for uplink, this is happens in reverse, causing the below trace. CT cleanup is called from: mlx5e_cleanup_rep_tx()->mlx5e_cleanup_uplink_rep_tx()-> mlx5e_rep_tc_cleanup()->mlx5e_tc_esw_cleanup()-> mlx5_tc_ct_clean() Only afterwards, tc cleanup is called from: mlx5e_cleanup_rep_tx()->mlx5e_tc_ht_cleanup() which would have deleted all the tc ct rules, and so delete all the offloaded tuples. Fix this reversing the order of init and on cleanup, which will result in tc cleanup then ct cleanup.

Currently usb_submit_urb is called directly to submit deferred tx urbs after unanchor them. So the usb_giveback_urb_bh would failed to unref it in usb_unanchor_urb and cause memory leak.
