2023-02-08drm/amd/display: fix cursor offset on rotation 180Melissa Wen
Cursor gets clipped off in the middle of the screen with hw rotation 180. Fix a miscalculation of cursor offset when it's placed near the edges in the pipe split case. Cursor bugs with hw rotation were reported on AMD issue tracker: https://gitlab.freedesktop.org/drm/amd/-/issues/2247 The issues on rotation 270 was fixed by: https://lore.kernel.org/amd-gfx/20221118125935.4013669-22-Brian.Chang@amd.com/ that partially addressed the rotation 180 too. So, this patch is the final bits for rotation 180.

2023-02-08selftests: mptcp: stop tests earlierMatthieu Baerts
These 'endpoint' tests from 'mptcp_join.sh' selftest start a transfer in the background and check the status during this transfer. Once the expected events have been recorded, there is no reason to wait for the data transfer to finish. It can be stopped earlier to reduce the execution time by more than half. For these tests, the exchanged data were not verified. Errors, if any, were ignored but that's fine, plenty of other tests are looking at that. It is then OK to mute stderr now that we are sure errors will be printed (and still ignored) because the transfer is stopped before the end.

2023-02-08mptcp: be careful on subflow status propagation on errorsPaolo Abeni
Currently the subflow error report callback unconditionally propagates the fallback subflow status to the owning msk. If the msk is already orphaned, the above prevents the code from correctly tracking the msk moving to the TCP_CLOSE state and doing the appropriate cleanup. All the above causes increasing memory usage over time and sporadic self-tests failures. There is a great deal of infrastructure trying to propagate correctly the fallback subflow status to the owning mptcp socket, e.g. via mptcp_subflow_eof() and subflow_sched_work_if_closed(): in the error propagation path we need only to cope with unorphaned sockets.

2023-02-08mptcp: fix locking for in-kernel listener creationPaolo Abeni
For consistency, in mptcp_pm_nl_create_listen_socket(), we need to call the __mptcp_nmpc_socket() under the msk socket lock. Note that as a side effect, mptcp_subflow_create_socket() needs a 'nested' lockdep annotation, as it will acquire the subflow (kernel) socket lock under the in-kernel listener msk socket lock. The current lack of locking is almost harmless, because the relevant socket is not exposed to the user space, but in future we will add more complexity to the mentioned helper, let's play safe.

2023-02-08mptcp: do not wait for bare sockets' timeoutPaolo Abeni
If the peer closes all the existing subflows for a given mptcp socket and later the application closes it, the current implementation let it survive until the timewait timeout expires. While the above is allowed by the protocol specification it consumes resources for almost no reason and additionally causes sporadic self-tests failures. Let's move the mptcp socket to the TCP_CLOSE state when there are no alive subflows at close time, so that the allocated resources will be freed immediately.

2023-02-08net: ethernet: mtk_eth_soc: fix DSA TX tag hwaccel for switch port 0Vladimir Oltean
Arınç reports that on his MT7621AT Unielec U7621-06 board and MT7623NI Bananapi BPI-R2, packets received by the CPU over mt7530 switch port 0 (of which this driver acts as the DSA master) are not processed correctly by software. More precisely, they arrive without a DSA tag (in packet or in the hwaccel area - skb_metadata_dst()), so DSA cannot demux them towards the switch's interface for port 0. Traffic from other ports receives a skb_metadata_dst() with the correct port and is demuxed properly. Looking at mtk_poll_rx(), it becomes apparent that this driver uses the skb vlan hwaccel area: union { u32 vlan_all; struct { __be16 vlan_proto; __u16 vlan_tci; }; }; as a temporary storage for the VLAN hwaccel tag, or the DSA hwaccel tag. If this is a DSA master it's a DSA hwaccel tag, and finally clears up the skb VLAN hwaccel header. I'm guessing that the problem is the (mis)use of API. skb_vlan_tag_present() looks like this: #define skb_vlan_tag_present(__skb) (!!(__skb)->vlan_all) So if both vlan_proto and vlan_tci are zeroes, skb_vlan_tag_present() returns precisely false. I don't know for sure what is the format of the DSA hwaccel tag, but I surely know that lowermost 3 bits of vlan_proto are 0 when receiving from port 0: unsigned int port = vlan_proto & GENMASK(2, 0); If the RX descriptor has no other bits set to non-zero values in RX_DMA_VTAG, then the call to __vlan_hwaccel_put_tag() will not, in fact, make the subsequent skb_vlan_tag_present() return true, because it's implemented like this: static inline void __vlan_hwaccel_put_tag(struct sk_buff *skb, __be16 vlan_proto, u16 vlan_tci) { skb->vlan_proto = vlan_proto; skb->vlan_tci = vlan_tci; } What we need to do to fix this problem (assuming this is the problem) is to stop using skb->vlan_all as temporary storage for driver affairs, and just create some local variables that serve the same purpose, but hopefully better. Instead of calling skb_vlan_tag_present(), let's look at a boolean has_hwaccel_tag which we set to true when the RX DMA descriptors have something. Disambiguate based on netdev_uses_dsa() whether this is a VLAN or DSA hwaccel tag, and only call __vlan_hwaccel_put_tag() if we're certain it's a VLAN tag. Arınç confirms that the treatment works, so this validates the assumption.

Currently, each core device has VF pages counter which stores number of fw pages used by its VFs and SFs. The current design led to a hang when performing firmware reset on DPU, where the DPU PFs stalled in sriov unload flow due to waiting on release of SFs pages instead of waiting on only VFs pages.

2023-02-07net/mlx5e: Update rx ring hw mtu upon each rx-fcs flag changeAdham Faris
rq->hw_mtu is used in function en_rx.c/mlx5e_skb_from_cqe_mpwrq_linear() to catch oversized packets. If FCS is concatenated to the end of the packet then the check should be updated accordingly. Rx rings initialization (mlx5e_init_rxq_rq()) invoked for every new set of channels, as part of mlx5e_safe_switch_params(), unknowingly if it runs with default configuration or not. Current rq->hw_mtu initialization assumes default configuration and ignores params->scatter_fcs_en flag state. Fix this, by accounting for params->scatter_fcs_en flag state during rq->hw_mtu initialization. In addition, updating rq->hw_mtu value during ingress traffic might lead to packets drop and oversize_pkts_sw_drop counter increase with no good reason. Hence we remove this optimization and switch the set of channels with a new one, to make sure we don't get false positives on the oversize_pkts_sw_drop counter.

2023-02-07cxl/region: Fix passthrough-decoder detectionDan Williams
A passthrough decoder is a decoder that maps only 1 target. It is a special case because it does not impose any constraints on the interleave-math as compared to a decoder with multiple targets. Extend the passthrough case to multi-target-capable decoders that only have one target selected. I.e. the current code was only considering passthrough *ports* which are only a subset of the potential passthrough decoder scenarios.

2023-02-07can: j1939: do not wait 250 ms if the same addr was already claimedDevid Antonio Filoni
The ISO 11783-5 standard, in "4.5.2 - Address claim requirements", states: d) No CF shall begin, or resume, transmission on the network until 250 ms after it has successfully claimed an address except when responding to a request for address-claimed. But "Figure 6" and "Figure 7" in "4.5.4.2 - Address-claim prioritization" show that the CF begins the transmission after 250 ms from the first AC (address-claimed) message even if it sends another AC message during that time window to resolve the address contention with another CF. As stated in "4.4.2.3 - Address-claimed message": In order to successfully claim an address, the CF sending an address claimed message shall not receive a contending claim from another CF for at least 250 ms. As stated in "4.4.3.2 - NAME management (NM) message": 1) A commanding CF can d) request that a CF with a specified NAME transmit the address- claimed message with its current NAME. 2) A target CF shall d) send an address-claimed message in response to a request for a matching NAME Taking the above arguments into account, the 250 ms wait is requested only during network initialization. Do not restart the timer on AC message if both the NAME and the address match and so if the address has already been claimed (timer has expired) or the AC message has been sent to resolve the contention with another CF (timer is still running).
