In the Linux kernel, the following vulnerability has been resolved:
scsi: ufs: Fix a deadlock in the error handler
The following deadlock has been observed on a test setup:
- All tags allocated
- The SCSI error handler calls ufshcd_eh_host_reset_handler()
- ufshcd_eh_host_reset_handler() queues work that calls
ufshcd_err_handler()
- ufshcd_err_handler() locks up as follows:
Workqueue: ufs_eh_wq_0 ufshcd_err_handler.cfi_jt
Call trace:

Fix this lockup by making ufshcd_exec_dev_cmd() allocate a reserved
request.
