2024-05-03bnxt: fix bnxt_get_avail_msix() returning negative valuesDavid Wei
Current net-next/main does not boot for older chipsets e.g. Stratus. Sample dmesg: [ 11.368315] bnxt_en 0000:02:00.0 (unnamed net_device) (uninitialized): Able to reserve only 0 out of 9 requested RX rings [ 11.390181] bnxt_en 0000:02:00.0 (unnamed net_device) (uninitialized): Unable to reserve tx rings [ 11.438780] bnxt_en 0000:02:00.0 (unnamed net_device) (uninitialized): 2nd rings reservation failed. [ 11.487559] bnxt_en 0000:02:00.0 (unnamed net_device) (uninitialized): Not enough rings available. [ 11.506012] bnxt_en 0000:02:00.0: probe with driver bnxt_en failed with error -12 This is caused by bnxt_get_avail_msix() returning a negative value for these chipsets not using the new resource manager i.e. !BNXT_NEW_RM. This in turn causes hwr.cp in __bnxt_reserve_rings() to be set to 0. In the current call stack, __bnxt_reserve_rings() is called from bnxt_set_dflt_rings() before bnxt_init_int_mode(). Therefore, bp->total_irqs is always 0 and for !BNXT_NEW_RM bnxt_get_avail_msix() always returns a negative number. Historically, MSIX vectors were requested by the RoCE driver during run-time and bnxt_get_avail_msix() was used for this purpose. Today, RoCE MSIX vectors are statically allocated. bnxt_get_avail_msix() should only be called for the BNXT_NEW_RM() case to reserve the MSIX ahead of time for RoCE use. bnxt_get_avail_msix() is also be simplified to handle the BNXT_NEW_RM() case only.

2024-05-03net: ks8851: Queue RX packets in IRQ handler instead of disabling BHsMarek Vasut
Currently the driver uses local_bh_disable()/local_bh_enable() in its IRQ handler to avoid triggering net_rx_action() softirq on exit from netif_rx(). The net_rx_action() could trigger this driver .start_xmit callback, which is protected by the same lock as the IRQ handler, so calling the .start_xmit from netif_rx() from the IRQ handler critical section protected by the lock could lead to an attempt to claim the already claimed lock, and a hang. The local_bh_disable()/local_bh_enable() approach works only in case the IRQ handler is protected by a spinlock, but does not work if the IRQ handler is protected by mutex, i.e. this works for KS8851 with Parallel bus interface, but not for KS8851 with SPI bus interface. Remove the BH manipulation and instead of calling netif_rx() inside the IRQ handler code protected by the lock, queue all the received SKBs in the IRQ handler into a queue first, and once the IRQ handler exits the critical section protected by the lock, dequeue all the queued SKBs and push them all into netif_rx(). At this point, it is safe to trigger the net_rx_action() softirq, since the netif_rx() call is outside of the lock that protects the IRQ handler.

2024-05-03wifi: iwlwifi: pcie: allocate dummy net_device dynamicallyBreno Leitao
struct net_device shouldn't be embedded into any structure, instead, the owner should use the priv space to embed their state into net_device. Embedding net_device into structures prohibits the usage of flexible arrays in the net_device structure. For more details, see the discussion at [1]. Un-embed the net_device from struct iwl_trans_pcie by converting it into a pointer. Then use the leverage alloc_netdev() to allocate the net_device object at iwl_trans_pcie_alloc. The private data of net_device becomes a pointer for the struct iwl_trans_pcie, so, it is easy to get back to the iwl_trans_pcie parent given the net_device object.

Since commit a3c53be55c95 ("net: dsa: mv88e6xxx: Support multiple MDIO busses") mv88e6xxx_default_mdio_bus() has checked that the return value of list_first_entry() is non-NULL. This appears to be intended to guard against the list chip->mdios being empty. However, it is not the correct check as the implementation of list_first_entry is not designed to return NULL for empty lists. Instead, use list_first_entry_or_null() which does return NULL if the list is empty. Flagged by Smatch. Compile tested only.

2024-05-02bnxt_en: Optimize recovery path ULP locking in the driverKalesh AP
In the error recovery path (AER, firmware recovery, etc), the driver notifies the RoCE driver via ULP_STOP before the reset and via ULP_START after the reset, all under RTNL_LOCK. The RoCE driver can take a long time if there are a lot of QPs to destroy, so it is not ideal to hold the global RTNL lock. Rely on the new en_dev_lock mutex instead for ULP_STOP and ULP_START. For the most part, we move the ULP_STOP call before we take the RTNL lock and move the ULP_START after RTNL unlock. Note that SRIOV re-enablement must be done after ULP_START or RoCE on the VFs will not resume properly after reset. The one scenario in bnxt_hwrm_if_change() where the RTNL lock is already taken in the .ndo_open() context requires the ULP restart to be deferred to the bnxt_sp_task() workqueue.

Add a new en_dev_lock mutex so that the asynchronous ULP_STOP and ULP_START operations can be serialized with bnxt_register_dev() and bnxt_unregister_dev() calls without relying on the RTNL lock.

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.

2024-05-02wifi: mt76: mt7921s: fix potential hung tasks during chip recoveryLeon Yen
During chip recovery (e.g. chip reset), there is a possible situation that kernel worker reset_work is holding the lock and waiting for kernel thread stat_worker to be parked, while stat_worker is waiting for the release of the same lock. It causes a deadlock resulting in the dumping of hung tasks messages and possible rebooting of the device. This patch prevents the execution of stat_worker during the chip recovery.
