libata: Return correct status in sata_pmp_eh_recover_pm() when ATA_DFLAG_DETACH is set

2020-04-07T20:45:15Z

During system resume from suspend, this can be observed on ASM1062 PMP controller: ata10.01: SATA link down (SStatus 0 SControl 330) ata10.02: hard resetting link ata10.02: SATA link down (SStatus 0 SControl 330) ata10.00: configured for UDMA/133 Kernel panic - not syncing: stack-protector: Kernel in: sata_pmp_eh_recover+0xa2b/0xa40 CPU: 2 PID: 230 Comm: scsi_eh_9 Tainted: P OE #49-Ubuntu Hardware name: System manufacturer System Product 1001 12/10/2017 Call Trace: dump_stack+0x63/0x8b panic+0xe4/0x244 ? sata_pmp_eh_recover+0xa2b/0xa40 __stack_chk_fail+0x19/0x20 sata_pmp_eh_recover+0xa2b/0xa40 ? ahci_do_softreset+0x260/0x260 [libahci] ? ahci_do_hardreset+0x140/0x140 [libahci] ? ata_phys_link_offline+0x60/0x60 ? ahci_stop_engine+0xc0/0xc0 [libahci] sata_pmp_error_handler+0x22/0x30 ahci_error_handler+0x45/0x80 [libahci] ata_scsi_port_error_handler+0x29b/0x770 ? ata_scsi_cmd_error_handler+0x101/0x140 ata_scsi_error+0x95/0xd0 ? scsi_try_target_reset+0x90/0x90 scsi_error_handler+0xd0/0x5b0 kthread+0x121/0x140 ? scsi_eh_get_sense+0x200/0x200 ? kthread_create_worker_on_cpu+0x70/0x70 ret_from_fork+0x22/0x40 Kernel Offset: 0xcc00000 from 0xffffffff81000000 (relocation range: 0xffffffff80000000-0xffffffffbfffffff) Since sata_pmp_eh_recover_pmp() doens't set rc when ATA_DFLAG_DETACH is set, sata_pmp_eh_recover() continues to run. During retry it triggers the stack protector. Set correct rc in sata_pmp_eh_recover_pmp() to let sata_pmp_eh_recover() jump to pmp_fail directly.
