This could lead to double free issue in a scenario where ath11k_hal_srng_deinit() is invoked back to back. In the current code, although the chances are very low, the above said scenario could happen when hardware recovery has failed and then there is another FW assert where ath11k_hal_srng_deinit() is invoked once again as part of recovery. Fix this by assigning the struct ath11k_hal::srng_config pointer to NULL after freeing the memory.

Modify print_array_to_buf() to call print_array_to_buf_index() with 0 as the starting index.

For targets such as WCN6750 in which CE address space is same as WCSS address space (i.e. "ce_remap" hw_param is set to false), mem_ce and mem iomem addresses are same. In the initial SRNG setup for such targets, the CE offset address and hence CE register base addresses are calculated correctly in ath11k_hal_srng_init() as both mem and mem_ce are initialized with same iomem address. Later, after the firmware download, mem is initialized with BAR address received in qmi_wlanfw_device_info_resp_msg_v01 QMI message, while mem_ce is not updated. After initial setup success, during Subsystem Restart (SSR), as part of reinitialization, ath11k_hal_srng_init() will be called again, and CE offset address will be calculated incorrectly this time as mem_ce address was not updated. Due to the incorrect CE offset address, APPS accesses an invalid CE register address which leads to improper behavior in firmware after SSR is triggered. To fix the above issue, update mem_ce to mem iomem address in ath11k_qmi_request_device_info() for targets which do not support ce_remap feature.

Fix that by switching to use recently introduced ieee80211_iterate_stations_mtx(). Do note that WCN6855 firmware is still crashing, I'm not sure if that firmware even supports bitrate WMI commands and should we consider disabling ath12k_mac_op_set_bitrate_mask() for WCN6855? But that's for another patch.

The benefits are: * one lock less and simplified locking * possibility to use wiphy_work_queue() without other locks Most of the mac80211 ops are called within wiphy_lock(), most notable exception being tx op. This can be checked with lockdep_assert_wiphy() from net/mac80211/driver-ops.[ch] and I veried that by manually going through all the ops in ath12k_ops which had lockdep_assert_wiphy(). The conversion was simple: * All conf_mutex lock() and unlock() calls which already were called under wiphy_lock() I replaced with lockdep_assert_wiphy(). * The rest of conf_mutex calls I replaced with wiphy_lock() and wiphy_unlock(). * All lockdep_asset_held(conf_mutex) calls I replaced with lockdep_assert_wiphy(). One exception was in ath12k_core_post_reconfigure_recovery() where the wiphy lock needs to be taken before hw_mutex to avoid a lockdep warning.

Sleep timer will be deleted before ath10k_core_destroy() in ath10k_hif_power_down(). ath10k_sdio_irq_disable() only be called in ath10k_hif_stop(). ath10k_core_unregister() will call ath10k_hif_power_down() to stop hif bus, so ath10k_sdio_hif_tx_sg() won't be called anymore.

Add firmware coredump collection support for PCI bus. Collect RDDM and firmware paging dumps from MHI and pack them in TLV format and also pack various memory shared during QMI phase in separate TLVs. Add necessary header and share the dumps to user space using dev coredump framework. Coredump collection is disabled by default and can be enabled using menuconfig. Dump collected for a radio is 55 MB approximately.

This requires changing the use of arvif to per link and not per hw which can now comprise of multiple links. Also since most configurations from mac80211 are done per link, do refactoring of the driver functions to apply these configurations at link level. Split ath12k_vif which is the driver private of ieee80211_vif to store link specific information as ath12k_link_vif. For default use cases the ath12k vif will have a preallocated link vif called deflink which will be used by non ML and the first link vif of ML vif. With MLO support to be added, remaining link vifs will be allocated during channel assignment where vdev create/start happens. These link vifs will be freed during interface down.

In this patch set, only deflink is used to be on par with the existing code. When MLO support is added the link id will be used to fetch the arvif. 3. For mac80211 ops which doesn't use specific link_id, the config or info is common for the vif, hence apply the config to all link vifs. The links_map in the ahvif, will be used to identify all the link vifs that are setup. 4. Change ath12k_vif_to_arvif() as ath12k_vif_to_ahvif() to fetch the hw level vif. The link vif can be fetched from ahvif->link[], or the deflink can be accessed via ahvif->deflink. API to access link vif (arvif) by passing link_id can be introduced with MLO Support. 5. The ieee80211_vif can be accessed from ahvif using ath12k_ahvif_to_vif(). The locking continues to use wiphy_lock() for protecting access to most data in struct ath12k&co, there are no changes in that regard. Though struct ath12k_vif::link[] is protected with RCU.

With MLO support being added multiple link vifs can be part of an ieee80211_vif/ahvif and all these functions will need link id along with ieee80211_vif/ahvif to be passed to fetch the corresponding link vif (arvif) to which the control/config applies. Also all these functions need to validate the locking dependency before dereferencing and start using the link vifs. To avoid these redundant link dereferences and validations, limit ieee80211_vif/ahvif argument to mac80211 ops unless otherwise really required. Do link vif dereference only in mac80211 ops. Replace vif arg with ath12k_link_vif and internally fetch ath12k_vif (ahvif) and vif (ieee80211_vif) if required on other functions.

This requires changing the use of arsta to per link and not per hw which can now comprise of multiple links. Also since most configurations from mac80211 are done per link, do refactoring of the driver functions to apply these configurations at link level. Split struct ath12k_sta, which is the driver private of struct ieee80211_sta, to store link specific information as struct ath12k_link_sta. For default use cases struct ath12k_sta will have a preallocated link sta called deflink which will be used by non ML STAs and the first link sta of ML STA. With MLO support to be added, remaining link stas will allocated during state change where new STA is added. These link stas will be freed when STA is deleted. Current ath12k_sta(arsta) structure: +-----------------+ +----------------+ | | | | | ieee80211_sta | | ieee80211_sta | | private data | | private data | | | | | | ath12k_sta | | ath12k_sta | | (arsta) | | (arsta) | |+---------------+| | +-------------+| || *arvif (link || | |*arvif (link || || vif of an ar || | | vif of an ar|| || say 5GHz) || | | say 6GHz) || |+---------------+| | +-------------+| +-----------------+ +----------------+ New struct ath12k_sta (ahsta) containing ath12k_link_sta(s) (arsta) (deflink is preallocated member which is always the first link if ieee80211_sta is ML STA and is the only link sta otherwise): +---------------------------------------+ | ieee80211_sta | | private data | | | | ath12k_sta (ahsta) | | +-------------------------------------+ | | ath12k_link_sta deflink (arsta) | | | | | | *arvif (link vif of ar (5GHz)) | | +-------------------------------------+ | +-------------------------------------+ | | ath12k_link_sta *link (arsta) | | | | | | *arvif (link vif of ar (6GHz)) | | | | | +-------------------------------------+ | | +---------------------------------------+ To refactor existing ath12k_sta to make use of link stas, following changes are made: 1. Limit struct ieee80211_sta argument mac80211 ops unless otherwise really required. 2. struct ath12k_sta, now called by variable name arsta, stores multiple arstas (struct ah12k_link_sta) and also has a back pointer to struct ath12k_sta. 3. Pass struct ath12k_link_sta to mac functions that passed struct ieee80211_sta argument and fetch struct ath12k_sta (ahsta) and struct ieee80211_sta(sta) internally. This is done to avoid passing link id in all the functions and performing validation across these functions. Rather the validation and sta to arsta conversion can be done only at the mac80211 ops. 4. In this patchset, only ahsta->deflink is used to be on par with the existing code. When MLO support is added the link id will be used to fetch the arsta. 5. Change ath12k_sta_to_arsta() to ath12k_vif_to_ahsta() to fetch the ML level sta. The link sta can be fetched from ahsta->link[], or the deflink can be accessed via ahsta->deflink. API to access link sta (arsta) by passing link_id can be introduced with MLO Support. 6. The ieee80211_sta can be accessed from ahsta using ath12k_ahsta_to_sta() Tested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.0.1-00029-QCAHKSWPL_SILICONZ-1 Tested-on: WCN7850 hw2.0 PCI WLAN.HMT.1.0.c5-00481-QCAHMTSWPL_V1.0_V2.0_SILICONZ-3 Signed-off-by: Sriram R Co-developed-by: Rameshkumar Sundaram Signed-off-by: Rameshkumar Sundaram Signed-off-by: Kalle Valo Link: https://patch.msgid.link/20241015171416.518022-4-kvalo@kernel.org Signed-off-by: Jeff Johnson --- drivers/net/wireless/ath/ath12k/core.h | 20 ++- drivers/net/wireless/ath/ath12k/dp_mon.c | 14 +- drivers/net/wireless/ath/ath12k/dp_rx.c | 14 +- drivers/net/wireless/ath/ath12k/mac.c | 194 +++++++++++++++-------- 4 files changed, 167 insertions(+), 75 deletions(-) diff --git a/drivers/net/wireless/ath/ath12k/core.h b/drivers/net/wireless/ath/ath12k/core.h index eef4251fb8e0..c87f4783fb29 100644 --- a/drivers/net/wireless/ath/ath12k/core.h +++ b/drivers/net/wireless/ath/ath12k/core.h @@ -456,15 +456,15 @@ struct ath12k_wbm_tx_stats { u64 wbm_tx_comp_stats[HAL_WBM_REL_HTT_TX_COMP_STATUS_MAX];

With MLO changes the ieee80211_vif drv priv is now ahvif and its arvifs (struct ath12k_link_vif) other than deflink can be allocated dynamically during channel assignment. Hence maintain link level cache in ahvif and whenever channel is assigned for link vif and vdev is created, flush the corresponding link vif cache from ahvif. Current code uses cache of ATH12K_DEFAULT_LINK_ID (0) which is the cache of ahvif->deflink.

With MLO multiple links could be associated to the ahvif. Use link id from link_conf passed by mac80211 and do vdev create start for intended link of ahvif. Add ath12k_mac_assign_link_vif() helper to allocate and initialize link arvif object based on input link_id. The first link arvif that is being created in an ahvif will use preallocated ahvif->deflink object and the rest gets allocated. Currently link arvif can be removed in two call backs namely ath12k_mac_op_remove_interface() and ath12k_mac_op_unassign_vif_chanctx(): * ath12k_mac_op_unassign_vif_chanctx() carries link_info so obtain link_id from link_info and handle removal for that link * ath12k_mac_op_remove_interface() is done at interface/MLD level hence loop through the active link arvifs and remove all of them Add ath12k_mac_unassign_link_vif() helper to reset/destroy the link arvifs allocated for an ahvif. For scan request from mac80211, check if the any of the link arvifs of the ahvif is already created on the radio in which scan is requested and use it. If not use deflink(link 0) for creating scan arvif. Also ath12k creates vdev during assign_vif_chanctx() mac80211 op callback as it knows channel associated with given link only in this callback. Whereas mac80211 updates addition/deletion of links to an ML vif via .change_vif_links() callback and this is done before channel assignment. Hence register an dummy ath12k_mac_op_change_vif_links() function to change_vif_links() and acknowledge mac80211s link updates.

This is because the definition of the rx_msdu_end_wcn7850 structure in ath12k is incorrect. In fact, the rx_msdu_end structure used by WCN7850 is the same as the rx_msdu_end structure of QCN9274. Commit ed823fd113b7 ("wifi: ath12k: add msdu_end structure for WCN7850") introduced this structure. The original issue trying to be fixed with that commit is that the TID information retrieved from the rx_msdu_end structure was incorrect, and it was thought that the structure wasn't correct, so a supposedly correct structure was introduced. However it was subsequently discovered that the TID information is only guaranteed to be valid in the rx_msdu_start structure, so that commit added the logic to retrieve the TID from the rx_msdu_start, but unfortunately kept the rx_msdu_end_wcn7850 structure. To address this issue, revert the code related to the rx_msdu_end_wcn7850 structure, retaining the TID retrieval logic. This patch does not affect QCN9274.

Then host can use these status information to get specific information about this packet, such as l3 offset, bandwidth, mcs, packet type. If this packet is composed of multiple MSDUs, then hardware will only fill status information for the last(tail) MSDU. At this time, MSDU information is uncertain for others MSDUs. But current code use the first MSDU in monitor mode, so will get the wrong information. Fix it by getting msdu information from last(tail) msdu.

However the tasklet is marked deprecated and has some design flaws. To replace tasklets, BH workqueue support has been added. BH workqueue behaves similarly to regular workqueues except that the queued work items are executed in the BH context. Hence, convert the tasklet to BH workqueue for handling CE interrupts in the BH context.
