git://git.kernel.org/pub/scm/linux/kernel/git/wireless/wireless-next Kalle Valo says: ==================== wireless-next patches for v6.7 The first pull request for v6.7, with both stack and driver changes. We have a big change how locking is handled in cfg80211 and mac80211 which removes several locks and hopefully simplifies the locking overall. In drivers rtw89 got MCC support and smaller features to other active drivers but nothing out of ordinary. Major changes: cfg80211 - remove wdev mutex, use the wiphy mutex instead - annotate iftype_data pointer with sparse - first kunit tests, for element defrag - remove unused scan_width support mac80211 - major locking rework, remove several locks like sta_mtx, key_mtx etc. and use the wiphy mutex instead - remove unused shifted rate support - support antenna control in frame injection (requires driver support) - convert RX_DROP_UNUSABLE to more detailed reason codes rtw89 - TDMA-based multi-channel concurrency (MCC) support iwlwifi - support set_antenna() operation - support frame injection antenna control ath12k - WCN7850: enable 320 MHz channels in 6 GHz band - WCN7850: hardware rfkill support - WCN7850: enable IEEE80211_HW_SINGLE_SCAN_ON_ALL_BANDS to make scan faster ath11k - add chip id board name while searching board-2.bin * tag 'wireless-next-2023-10-06' of git://git.kernel.org/pub/scm/linux/kernel/git/wireless/wireless-next: (272 commits) wifi: rtlwifi: remove unreachable code in rtl92d_dm_check_edca_turbo() wifi: rtw89: debug: txpwr table supports Wi-Fi 7 chips wifi: rtw89: debug: show txpwr table according to chip gen wifi: rtw89: phy: set TX power RU limit according to chip gen wifi: rtw89: phy: set TX power limit according to chip gen wifi: rtw89: phy: set TX power offset according to chip gen wifi: rtw89: phy: set TX power by rate according to chip gen wifi: rtw89: mac: get TX power control register according to chip gen wifi: rtlwifi: use unsigned long for rtl_bssid_entry timestamp wifi: rtlwifi: fix EDCA limit set by BT coexistence wifi: rt2x00: fix MT7620 low RSSI issue wifi: rtw89: refine bandwidth 160MHz uplink OFDMA performance wifi: rtw89: refine uplink trigger based control mechanism wifi: rtw89: 8851b: update TX power tables to R34 wifi: rtw89: 8852b: update TX power tables to R35 wifi: rtw89: 8852c: update TX power tables to R67 wifi: rtw89: regd: configure Thailand in regulation type wifi: mac80211: add back SPDX identifier wifi: mac80211: fix ieee80211_drop_unencrypted_mgmt return type/value wifi: rtlwifi: cleanup few rtlxxxx_set_hw_reg() routines ... ==================== Link: https://lore.kernel.org/r/87jzrz6bvw.fsf@kernel.org Signed-off-by: Jakub Kicinski <kuba@kernel.org>

2023-10-05net_sched: sch_fq: add 3 bands and WRR schedulingEric Dumazet1-2/+9
Before Google adopted FQ for its production servers, we had to ensure AF4 packets would get a higher share than BE1 ones. As discussed this week in Netconf 2023 in Paris, it is time to upstream this for public use. After this patch FQ can replace pfifo_fast, with the following differences : - FQ uses WRR instead of strict prio, to avoid starvation of low priority packets. - We make sure each band/prio tracks its own usage against sch->limit. This was done to make sure flood of low priority packets would not prevent AF4 packets to be queued. Contributed by Willem. - priomap can be changed, if needed (default value are the ones coming from pfifo_fast). In this patch, we set default band weights so that : - high prio (band=0) packets get 90% of the bandwidth if they compete with low prio (band=2) packets. - high prio packets get 75% of the bandwidth if they compete with medium prio (band=1) packets. Following patch in this series adds the possibility to tune the per-band weights. As we added many fields in 'struct fq_sched_data', we had to make sure to have the first cache line read-mostly, and avoid wasting precious cache lines. More optimizations are possible but will be sent separately.

2023-10-01net_sched: sch_fq: add fast path for mostly idle qdiscEric Dumazet1-0/+1
TCQ_F_CAN_BYPASS can be used by few qdiscs. Idea is that if we queue a packet to an empty qdisc, following dequeue() would pick it immediately. FQ can not use the generic TCQ_F_CAN_BYPASS code, because some additional checks need to be performed. This patch adds a similar fast path to FQ. Most of the time, qdisc is not throttled, and many packets can avoid bringing/touching at least four cache lines, and consuming 128bytes of memory to store the state of a flow. After this patch, netperf can send UDP packets about 13 % faster, and pktgen goes 30 % faster (when FQ is in the way), on a fast NIC. TCP traffic is also improved, thanks to a reduction of cache line misses. I have measured a 5 % increase of throughput on a tcp_rr intensive workload. tc -s -d qd sh dev eth1 ... qdisc fq 8004: parent 1:2 limit 10000p flow_limit 100p buckets 1024 orphan_mask 1023 quantum 3028b initial_quantum 15140b low_rate_threshold 550Kbit refill_delay 40ms timer_slack 10us horizon 10s horizon_drop Sent 5646784384 bytes 1985161 pkt (dropped 0, overlimits 0 requeues 0) backlog 0b 0p requeues 0 flows 122 (inactive 122 throttled 0) gc 0 highprio 0 fastpath 659990 throttled 27762 latency 8.57us Signed-off-by: Eric Dumazet <edumazet@google.com> Signed-off-by: David S.

2023-09-17devlink: expose peer SF devlink instanceJiri Pirko1-0/+1
Introduce a new helper devl_port_fn_devlink_set() to be used by driver assigning a devlink instance to the peer devlink port function. Expose this to user over new netlink attribute nested under port function nest to expose devlink handle related to the port function. This is particularly helpful for user to understand the relationship between devlink instances created for SFs and the port functions they belong to. Note that caller of devlink_port_notify() needs to hold devlink instance lock, put the assertion to devl_port_fn_devlink_set() to make this requirement explicit. Also note the limitations that only allow to make this assignment for registered objects. Signed-off-by: Jiri Pirko <jiri@nvidia.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2023-09-17netdev: expose DPLL pin handle for netdeviceJiri Pirko1-1/+1
In case netdevice represents a SyncE port, the user needs to understand the connection between netdevice and associated DPLL pin. There might me multiple netdevices pointing to the same pin, in case of VF/SF implementation. Add a IFLA Netlink attribute to nest the DPLL pin handle, similar to how it is implemented for devlink port. Add a struct dpll_pin pointer to netdev and protect access to it by RTNL. Expose netdev_dpll_pin_set() and netdev_dpll_pin_clear() helpers to the drivers so they can set/clear the DPLL pin relationship to netdev. Note that during the lifetime of struct dpll_pin the pin handle does not change. Therefore it is save to access it lockless. It is drivers responsibility to call netdev_dpll_pin_clear() before dpll_pin_put().

2023-09-16tcp: new TCP_INFO stats for RTO eventsAananth V1-0/+12
The 2023 SIGCOMM paper "Improving Network Availability with Protective ReRoute" has indicated Linux TCP's RTO-triggered txhash rehashing can effectively reduce application disruption during outages. To better measure the efficacy of this feature, this patch adds three more detailed stats during RTO recovery and exports via TCP_INFO. Applications and monitoring systems can leverage this data to measure the network path diversity and end-to-end repair latency during network outages to improve their network infrastructure. The following counters are added to tcp_sock in order to track RTO events over the lifetime of a TCP socket. 1. u16 total_rto - Counts the total number of RTO timeouts. 2. u16 total_rto_recoveries - Counts the total number of RTO recoveries. 3. u32 total_rto_time - Counts the total time spent (ms) in RTO recoveries. (time spent in CA_Loss and CA_Recovery states) To compute total_rto_time, we add a new u32 rto_stamp field to tcp_sock. rto_stamp records the start timestamp (ms) of the last RTO recovery (CA_Loss). Corresponding fields are also added to the tcp_info struct.

2023-09-13uapi: stddef.h: Fix __DECLARE_FLEX_ARRAY for C++Alexey Dobriyan1-0/+6
__DECLARE_FLEX_ARRAY(T, member) macro expands to struct { struct {} __empty_member; T member[]; }; which is subtly wrong in C++ because sizeof(struct{}) is 1 not 0, changing UAPI structures layouts. This can be fixed by expanding to T member[]; Now g++ doesn't like "T member[]" either, throwing errors on the following code: struct S { union { T1 member1[]; T2 member2[]; }; }; or struct S { T member[]; }; Use "T member[0];" which seems to work and does the right thing wrt structure layout.

2023-09-01RISC-V: Add ptrace support for vectorsAndy Chiu1-0/+2
This patch add back the ptrace support with the following fix: - Define NT_RISCV_CSR and re-number NT_RISCV_VECTOR to prevent conflicting with gdb's NT_RISCV_CSR. - Use struct __riscv_v_regset_state to handle ptrace requests Since gdb does not directly include the note description header in Linux and has already defined NT_RISCV_CSR as 0x900, we decide to sync with gdb and renumber NT_RISCV_VECTOR to solve and prevent future conflicts.
