Description

In the Linux kernel, the following vulnerability has been resolved: scsi: hisi_sas: Fix a deadlock issue related to automatic dump If we issue a disabling PHY command, the device attached with it will go offline, if a 2 bit ECC error occurs at the same time, a hung task may be found: [ 4613.652388] INFO: task kworker/u256:0:165233 blocked for more than 120 seconds.

However, the internal abort timed out due to the 2 bit ECC error and triggers automatic dump. In addition, since the hisi_hba semaphore has been obtained, the dump cannot be executed and the controller cannot be reset. Therefore, the deadlocks occur on the following circular dependencies ---truncated---
