Zheng Wang 9c6da3b7f1 scsi: message: mptlan: Fix use after free bug in mptlan_remove() due to race condition ... [ Upstream commit f486893288 ] mptlan_probe() calls mpt_register_lan_device() which initializes the &priv->post_buckets_task workqueue. A call to mpt_lan_wake_post_buckets_task() will subsequently start the work. During driver unload in mptlan_remove() the following race may occur: CPU0 CPU1 |mpt_lan_post_receive_buckets_work() mptlan_remove() | free_netdev() | kfree(dev); | | | dev->mtu | //use Fix this by finishing the work prior to cleaning up in mptlan_remove(). [mkp: we really should remove mptlan instead of attempting to fix it] Signed-off-by: Zheng Wang <zyytlz.wz@163.com> Link: https://lore.kernel.org/r/20230318081635.796479-1-zyytlz.wz@163.com Signed-off-by: Martin K.
