Detail

In the Linux kernel, the following vulnerability has been resolved:

scsi: lpfc: Move cfg_log_verbose check before calling lpfc_dmp_dbg()

In an attempt to log message 0126 with LOG_TRACE_EVENT, the following hard lockup call trace hangs the system.

Call Trace:
_raw_spin_lock_irqsave+0x32/0x40
lpfc_dmp_dbg.part.32+0x28/0x220 [lpfc]
lpfc_cmpl_els_fdisc+0x145/0x460 [lpfc]
lpfc_sli_cancel_jobs+0x92/0xd0 [lpfc]
lpfc_els_flush_cmd+0x43c/0x670 [lpfc]
lpfc_els_flush_all_cmd+0x37/0x60 [lpfc]
lpfc_sli4_async_event_proc+0x956/0x1720 [lpfc]
lpfc_do_work+0x1485/0x1d70 [lpfc]
kthread+0x112/0x130
ret_from_fork+0x1f/0x40 Kernel panic - not syncing: Hard LOCKUP

The same CPU tries to claim the phba->port_list_lock twice.

Move the cfg_log_verbose checks as part of the lpfc_printf_vlog() and lpfc_printf_log() macros before calling lpfc_dmp_dbg(). There is no need to take the phba->port_list_lock within lpfc_dmp_dbg().
