Subject: [PATCH] scsi: qla2xxx: Completely fix fcport double free
Date: Tue, 10 Feb 2026 11:08:22 +0100 [thread overview]
Message-ID: <aYsDln9NFQQsPDgg@vova-pc> (raw)
In qla24xx_els_dcmd_iocb sp->free is set to qla2x00_els_dcmd_sp_free.
When an error happens, this function is called by qla2x00_sp_release,
when kref_put releases the first and the last reference.
qla2x00_els_dcmd_sp_free frees fcport by calling qla2x00_free_fcport.
Doing it one more time after kref_put is a bad idea.
Fixes: 82f522ae0d97 ("scsi: qla2xxx: Fix double free of fcport")
Fixes: 4895009c4bb7 ("scsi: qla2xxx: Prevent command send on chip reset")
