net: hns3: fix deadlock issue when externel_lb and reset are executed together
Source: NVD (National Vulnerability Database)
Vulnerability Description
In the Linux kernel, the following vulnerability has been resolved: net: hns3: fix deadlock issue when externel_lb and reset are executed together When externel_lb and reset are executed together, a deadlock may occur: [ 3147.217009] INFO: task kworker/u321:0:7 blocked for more than 120 seconds. [ 3147.230483] "echo 0 > /proc/sys/kernel/hung_task_timeout_secs" disables this message. [ 3147.238999] task:kworker/u321:0 state:D stack: 0 pid: 7 ppid: 2 flags:0x00000008 [ 3147.248045] Workqueue: hclge hclge_service_task [hclge] [ 3147.253957] Call trace: [ 3147.257093] __switch_to+0x7c/0xbc [ 3147.261183] __schedule+0x338/0x6f0 [ 3147.265357] schedule+0x50/0xe0 [ 3147.269185] schedule_preempt_disabled+0x18/0x24 [ 3147.274488] __mutex_lock.constprop.0+0x1d4/0x5dc [ 3147.279880] __mutex_lock_slowpath+0x1c/0x30 [ 3147.284839] mutex_lock+0x50/0x60 [ 3147.288841] rtnl_lock+0x20/0x2c [ 3147.292759] hclge_reset_prepare+0x68/0x90 [hclge] [ 3147.298239] hclge_reset_subtask+0x88/0xe0 [hclge] [ 3147.303718] hclge_reset_service_task+0x84/0x120 [hclge] [ 3147.309718] hclge_service_task+0x2c/0x70 [hclge] [ 3147.315109] process_one_work+0x1d0/0x490 [ 3147.319805] worker_thread+0x158/0x3d0 [ 3147.324240] kthread+0x108/0x13c [ 3147.328154] ret_from_fork+0x10/0x18 In externel_lb process, the hns3 driver call napi_disable() first, then the reset happen, then the restore process of the externel_lb will fail, and will not call napi_enable(). When doing externel_lb again, napi_disable() will be double call, cause a deadlock of rtnl_lock(). This patch use the HNS3_NIC_STATE_DOWN state to protect the calling of napi_disable() and napi_enable() in externel_lb process, just as the usage in ndo_stop() and ndo_start().
