2024-05-02bnxt_en: Don't call ULP_STOP/ULP_START during L2 resetMichael Chan
There is no need to call ULP_STOP and ULP_START before and after the L2 reset in bnxt_reset_task(). This L2 reset is done after detecting TX timeout, RX ring errors, or VF config changes. The L2 reset does not affect RoCE since the firmware is not reset and the backing store is left alone.

2024-05-02bnxt_en: Don't support offline self test when RoCE driver is loadedKalesh AP
Offline self test is a very disruptive operation for RoCE and requires all active QPs to be destroyed. With a large number of QPs, it can take a long time to destroy all the QPs and can timeout. Do not allow ethtool offline self test if the RoCE driver is registered on the device.

2024-05-02bnxt_en: share NQ ring sw_stats memory with subringsEdwin Peer
On P5_PLUS chips and later, the NQ rings have subrings for RX and TX completions respectively. These subrings are passed to the poll function instead of the base NQ, but each ring carries its own copy of the software ring statistics. For stats to be conveniently accessible in __bnxt_poll_work(), the statistics memory should either be shared between the NQ and its subrings or the subrings need to be included in the ethtool stats aggregation logic. This patch opts for the former, because it's more efficient and less confusing having the software statistics for a ring exist in a single place. Before this patch, the counter will not be displayed if the "wrong" cpr->sw_stats was used to increment a counter.

Naresh and Eric report several errors (corrupted elements in the dynamic key hash list), when running tdc.py or syzbot.

2024-05-02wifi: ath12k: fix the problem that down grade phy mode operationLingbo Kong
Currently, when using WCN7850 or QCN9274 as AP, ath12k always performs down grade phy mode operation regardless of whether the firmware supports EHT capability or not and then vdev will start in HE mode. When stations that support EHT capability try to connect to the AP, the AP will set phy mode to EHT after receiving the association request packet, and then send WMI_PEER_ASSOC_CMDID command to firmware, AP’s firmware will crash. This is because when the ath12k_mac_copy_sband_iftype_data() function handles EHT capability, it does not copy the EHT capability into the iftype[band][type] array according to the interface type. So, interface type should not be used as an index to get eht_cap in ath12k_mac_check_down_grade_phy_mode() function. To address this issue, use types_mask to select the eht_cap in ath12k_mac_check_down_grade_phy_mode() function. This patch affects QCN9274 and WCN7850 because they have the same issue.

2024-05-02Merge branch 'net-gro-add-flush-flush_id-checks-and-fix-wrong-offset-in-udp'Paolo Abeni
Richard Gobert says: ==================== net: gro: add flush/flush_id checks and fix wrong offset in udp This series fixes a bug in the complete phase of UDP in GRO, in which socket lookup fails due to using network_header when parsing encapsulated packets. The fix is to add network_offset and inner_network_offset to napi_gro_cb and use these offsets for socket lookup. In addition p->flush/flush_id should be checked in all UDP flows. The same logic from tcp_gro_receive is applied for all flows in udp_gro_receive_segment. This prevents packets with mismatching network headers (flush/flush_id turned on) from merging in UDP GRO. The original series includes a change to vxlan test which adds the local parameter to prevent similar future bugs. I plan to submit it separately to net-next.

2024-05-02net: gro: add flush check in udp_gro_receive_segmentRichard Gobert
GRO-GSO path is supposed to be transparent and as such L3 flush checks are relevant to all UDP flows merging in GRO. This patch uses the same logic and code from tcp_gro_receive, terminating merge if flush is non zero. Fixes: e20cf8d3f1f7 ("udp: implement GRO for plain UDP sockets.")

2024-05-02net: gro: fix udp bad offset in socket lookup by adding ↵Richard Gobert
{inner_}network_offset to napi_gro_cb Commits a602456 ("udp: Add GRO functions to UDP socket") and 57c67ff ("udp: additional GRO support") introduce incorrect usage of {ip,ipv6}_hdr in the complete phase of gro. The functions always return skb->network_header, which in the case of encapsulated packets at the gro complete phase, is always set to the innermost L3 of the packet. That means that calling {ip,ipv6}_hdr for skbs which completed the GRO receive phase (both in gro_list and *_gro_complete) when parsing an encapsulated packet's _outer_ L3/L4 may return an unexpected value. This incorrect usage leads to a bug in GRO's UDP socket lookup. udp{4,6}_lib_lookup_skb functions use ip_hdr/ipv6_hdr respectively. These *_hdr functions return network_header which will point to the innermost L3, resulting in the wrong offset being used in __udp{4,6}_lib_lookup with encapsulated packets. This patch adds network_offset and inner_network_offset to napi_gro_cb, and makes sure both are set correctly. To fix the issue, network_offsets union is used inside napi_gro_cb, in which both the outer and the inner network offsets are saved.
