2025-03-07wifi: iwlwifi: trans: cancel restart work on op mode leaveMiri Korenblit1-0/+2
If the restart work happens to run after the opmode left (i.e. called iwl_trans_op_mode_leave), then the opmode memory (including its mutex) is likely to be freed already, and trans->opmode is NULL. Although the hw is stopped in that stage, which means that this restart got aborted (i.e. STATUS_RESET_PENDING will be cleared), it still can access trans->opmode (NULL pointer dereference) or the opmodes memory (which is freed). Fix this by canceling the restart wk in iwl_trans_op_mode_leave. Also make sure that the restart wk is really aborted.

2025-03-07wifi: iwlwifi: mvm: fix PNVM timeout for non-MSI-X platformsEmmanuel Grumbach1-3/+3
When MSI-X is not enabled, we mask all the interrupts in the interrupt handler and re-enable them when the interrupt thread runs. If STATUS_INT_ENABLED is not set, we won't re-enable in the thread. In order to get the ALIVE interrupt, we allow the ALIVE interrupt itself, and RX as well in order to receive the ALIVE notification (which is received as an RX from the firmware. The problem is that STATUS_INT_ENABLED is clear until the op_mode calls trans_fw_alive which means that until trans_fw_alive is called, any notification from the firmware will not be received. This became a problem when we inserted the pnvm_load exactly between the ALIVE and trans_fw_alive. Fix that by calling trans_fw_alive before loading the PNVM. This will allow to get the notification from the firmware about PNVM load being complete and continue the flow normally. This didn't happen on MSI-X because we don't disable the interrupts in the ISR when MSI-X is available. The error in the log looks like this: iwlwifi 0000:00:03.0: Timeout waiting for PNVM load! iwlwifi 0000:00:03.0: Failed to start RT ucode: -110 iwlwifi 0000:00:03.0: WRT: Collecting data: ini trigger 13 fired (delay=0ms).

2025-03-07net/mlx5e: Enable lanes configuration when auto-negotiation is offShahar Shitrit3-55/+67
Currently, when auto-negotiation is disabled, the driver retrieves the speed and converts it into all link modes that correspond to that speed. With this patch, we add the ability to set the number of lanes, so that the combination of speed and lanes corresponds to exactly one specific link mode for the extended bit map. For the legacy bit map the driver sets all link modes correspond to speed and lanes. This change provides users with the option to set a specific link mode, rather than enabling all link modes associated with a given speed when auto-negotiation is off.

2025-03-07net: stmmac: simplify phylink_suspend() and phylink_resume() callsRussell King (Oracle)1-14/+8
Currently, the calls to phylink's suspend and resume functions are inside overly complex tests, and boil down to: if (device_may_wakeup(priv->device) && priv->plat->pmt) { call phylink } else { call phylink and if (device_may_wakeup(priv->device)) do something else } This results in phylink always being called, possibly with differing arguments for phylink_suspend(). Simplify this code, noting that each site is slightly different due to the order in which phylink is called and the "something else".

2025-03-07net: stmmac: mostly remove "buf_sz"Russell King (Oracle)1-6/+1
The "buf_sz" parameter is not used in the stmmac driver - there is one place where the value of buf_sz is validated, and two places where it is written. It is otherwise unused. Remove these accesses. However, leave the module parameter in place as removing it could cause module load to fail, breaking user setups.

2025-03-06eth: bnxt: remove most dependencies on RTNLStanislav Fomichev6-73/+96
Only devlink and sriov paths are grabbing rtnl explicitly. The rest is covered by netdev instance lock which the core now grabs, so there is no need to manage rtnl in most places anymore. On the core side we can now try to drop rtnl in some places (do_setlink for example) for the drivers that signal non-rtnl mode (TBD). Boot-tested and with `ethtool -L eth1 combined 24` to trigger reset.

Protect all ethtool callbacks and PHY related state with the netdev instance lock, for drivers which want / need to have their ops instance-locked. Basically take the lock everywhere we take rtnl_lock. It was tempting to take the lock in ethnl_ops_begin(), but turns out we actually nest those calls (when generating notifications).

For the drivers that use queue management API, switch to the mode where core stack holds the netdev instance lock. This affects the following drivers: - bnxt - gve - netdevsim Originally I locked only start/stop, but switched to holding the lock over all iterations to make them look atomic to the device (feels like it should be easier to reason about).

For the drivers that use shaper API, switch to the mode where core stack holds the netdev lock. This affects two drivers: * iavf - already grabs netdev lock in ndo_open/ndo_stop, so mostly remove these * netdevsim - switch to _locked APIs to avoid deadlock iavf_close diff is a bit confusing, the existing call looks like this: iavf_close() { netdev_lock() .. netdev_unlock() wait_event_timeout(down_waitqueue) } I change it to the following: netdev_lock() iavf_close() { .. netdev_unlock() wait_event_timeout(down_waitqueue) netdev_lock() // reusing this lock call } netdev_unlock() Since I'm reusing existing netdev_lock call, so it looks like I only add netdev_unlock.
