Reported-by: kernel test robot Closes: https://lore.kernel.org/oe-kbuild-all/202406120146.xchlZbqX-lkp@ intel.com/ Reviewed-by: Sesidhar Baddela Signed-off-by: Gian Carlo Boffa Signed-off-by: Arulprabhu Ponnusamy Signed-off-by: Arun Easi Signed-off-by: Karan Tilak Kumar --- Changes between v2 and v3: Fix issue found by kernel test robot. Remove fnic_std_ba_acc definition to fix compilation warning. Incorporate review comments from Hannes: Replace redundant definitions with standard definitions. Replace static OXIDs with pool-based OXIDs for targets. Changes between v1 and v2: Incorporate review comments from Hannes: Use the correct kernel-doc format. Replace htonll() with get_unaligned_be64(). Replace fnic_del_fabric_timer_sync macro calls to function calls. Replace fnic_del_tport_timer_sync macro calls to function calls. Rename fc_abts_s to fc_tport_abts_s. Modify fc_tport_abts_s to be a global frame. Rename variable pfc_abts to tport_abts. Replace definitions with standard definitions from fc_els.h. Modify functions with returns in the middle to if else clauses. Replace simultaneous use of fc_tport_abts_s and tport_abts with just tport_abts. --- drivers/scsi/fnic/fdls_disc.c | 1567 +++++++++++++++++++++++++++++++-- drivers/scsi/fnic/fnic.h | 6 + drivers/scsi/fnic/fnic_fdls.h | 2 +- 3 files changed, 1501 insertions(+), 74 deletions(-) diff --git a/drivers/scsi/fnic/fdls_disc.c b/drivers/scsi/fnic/fdls_disc.c index d203398b2743..0757b9ab1a28 100644 --- a/drivers/scsi/fnic/fdls_disc.c +++ b/drivers/scsi/fnic/fdls_disc.c @@ -11,6 +11,10 @@ #include #include +#define FC_FC4_TYPE_SCSI 0x08 + +static void fdls_send_rpn_id(struct fnic_iport_s *iport);

This protocol will be exercised on Cisco UCS rack servers. Add support to specifically print FIP related debug messages. Replace existing definitions to handle new data structures. Clean up old and obsolete definitions. Reviewed-by: Sesidhar Baddela Signed-off-by: Gian Carlo Boffa Signed-off-by: Arulprabhu Ponnusamy Signed-off-by: Arun Easi Signed-off-by: Karan Tilak Kumar --- Changes between v2 and v3: Incorporate review comments from Hannes: Replace redundant definitions with standard definitions. Incorporate review comments from John: Replace GFP_ATOMIC with GFP_KERNEL where applicable. Changes between v1 and v2: Incorporate review comments from Hannes from other patches: Use the correct kernel-doc format. Replace htonll() with get_unaligned_be64(). Replace definitions with standard definitions from fc_els.h. Incorporate review comments from John: Remove unreferenced variable. Use standard definitions of true and false. Replace if else clauses with switch statement. Use kzalloc instead of kmalloc. --- drivers/scsi/fnic/Makefile | 1 + drivers/scsi/fnic/fip.c | 854 ++++++++++++++++++++++++++++++++ drivers/scsi/fnic/fip.h | 345 +++++++++++++ drivers/scsi/fnic/fnic.h | 23 +- drivers/scsi/fnic/fnic_fcs.c | 885 ++++++---------------------------- drivers/scsi/fnic/fnic_main.c | 47 +- 6 files changed, 1381 insertions(+), 774 deletions(-) create mode 100644 drivers/scsi/fnic/fip.c create mode 100644 drivers/scsi/fnic/fip.h diff --git a/drivers/scsi/fnic/Makefile b/drivers/scsi/fnic/Makefile index af156c69da0c..c025e875009e 100644 --- a/drivers/scsi/fnic/Makefile +++ b/drivers/scsi/fnic/Makefile @@ -2,6 +2,7 @@ obj-$(CONFIG_FCOE_FNIC) += fnic.o fnic-y := \ + fip.o\ fnic_attrs.o \ fnic_isr.o \ fnic_main.o \ diff --git a/drivers/scsi/fnic/fip.c b/drivers/scsi/fnic/fip.c new file mode 100644 index 000000000000..870b8e64a75c --- /dev/null +++ b/drivers/scsi/fnic/fip.c @@ -0,0 +1,854 @@ +// SPDX-License-Identifier: GPL-2.0-only +/* + * Copyright 2008 Cisco Systems, Inc.

Refactor code in fnic_probe and fnic_remove. Get fnic from shost_priv. Add error handling in stats processing functions. Modify some print statements. Add support to do module unload cleanup. Use placeholder functions/modify function declarations to not break compilation. Reviewed-by: Sesidhar Baddela Reviewed-by: Arulprabhu Ponnusamy Reviewed-by: Gian Carlo Boffa Signed-off-by: Arun Easi Signed-off-by: Karan Tilak Kumar --- Changes between v2 and v3: Modify scsi_unload to fix null pointer exception during fnic_remove. Replace fnic->host with fnic->lport->host to prevent compilation errors. Changes between v1 and v2: Incorporate review comments from Hannes from other patches: Replace pr_info with dev_info. Replace pr_err with dev_err. --- drivers/scsi/fnic/fnic.h | 12 +- drivers/scsi/fnic/fnic_attrs.c | 12 +- drivers/scsi/fnic/fnic_debugfs.c | 28 +- drivers/scsi/fnic/fnic_fcs.c | 16 + drivers/scsi/fnic/fnic_main.c | 491 +++++++++++++++++-------------- drivers/scsi/fnic/fnic_res.c | 30 +- drivers/scsi/fnic/fnic_scsi.c | 39 +++ drivers/scsi/fnic/fnic_trace.c | 6 + 8 files changed, 384 insertions(+), 250 deletions(-) diff --git a/drivers/scsi/fnic/fnic.h b/drivers/scsi/fnic/fnic.h index c6fe9eec9a0c..58d864b59c89 100644 --- a/drivers/scsi/fnic/fnic.h +++ b/drivers/scsi/fnic/fnic.h @@ -81,6 +81,7 @@ #define IS_FNIC_FCP_INITIATOR(fnic) (fnic->role == FNIC_ROLE_FCP_INITIATOR) #define FNIC_FW_RESET_TIMEOUT 60000 /* mSec */ +#define FNIC_FCOE_MAX_CMD_LEN 16 /* Retry supported by rport (returned by PRLI service parameters) */ #define FNIC_FC_RP_FLAGS_RETRY 0x1 @@ -340,6 +341,7 @@ struct fnic { int fnic_num; enum fnic_role_e role; struct fnic_iport_s iport; + struct Scsi_Host *host; struct fc_lport *lport; struct fcoe_ctlr ctlr; /* FIP FCoE controller structure */ struct vnic_dev_bar bar0; @@ -458,11 +460,6 @@ struct fnic { ____cacheline_aligned struct vnic_intr intr[FNIC_MSIX_INTR_MAX]; }; -static inline struct fnic *fnic_from_ctlr(struct fcoe_ctlr *fip) -{ - return container_of(fip, struct fnic, ctlr); -} - extern struct workqueue_struct *fnic_event_queue; extern struct workqueue_struct *fnic_fip_queue; extern const struct attribute_group *fnic_host_groups[]; @@ -491,6 +488,7 @@ int fnic_eh_host_reset_handler(struct scsi_cmnd *sc); int fnic_host_reset(struct Scsi_Host *shost); void fnic_reset(struct Scsi_Host *shost); int fnic_issue_fc_host_lip(struct Scsi_Host *shost); +void fnic_get_host_port_state(struct Scsi_Host *shost); void fnic_scsi_fcpio_reset(struct fnic *fnic); int fnic_wq_copy_cmpl_handler(struct fnic *fnic, int copy_work_to_do, unsigned int cq_index); int fnic_wq_cmpl_handler(struct fnic *fnic, int); @@ -503,7 +501,7 @@ const char *fnic_state_to_str(unsigned int state); void fnic_mq_map_queues_cpus(struct Scsi_Host *host); void fnic_log_q_error(struct fnic *fnic); void fnic_handle_link_event(struct fnic *fnic); -void fnic_stats_debugfs_init(struct fnic *fnic); +int fnic_stats_debugfs_init(struct fnic *fnic); void fnic_stats_debugfs_remove(struct fnic *fnic); int fnic_is_abts_pending(struct fnic *, struct scsi_cmnd *); @@ -532,5 +530,7 @@ unsigned int fnic_count_lun_ioreqs_wq(struct fnic *fnic, u32 hwq, struct scsi_device *device); unsigned int fnic_count_lun_ioreqs(struct fnic *fnic, struct scsi_device *device); +void fnic_scsi_unload(struct fnic *fnic); +void fnic_scsi_unload_cleanup(struct fnic *fnic); #endif /* _FNIC_H_ */ diff --git a/drivers/scsi/fnic/fnic_attrs.c b/drivers/scsi/fnic/fnic_attrs.c index 0c5e57c7e322..705718f0809b 100644 --- a/drivers/scsi/fnic/fnic_attrs.c +++ b/drivers/scsi/fnic/fnic_attrs.c @@ -11,8 +11,8 @@ static ssize_t fnic_show_state(struct device *dev, struct device_attribute *attr, char *buf) { - struct fc_lport *lp = shost_priv(class_to_shost(dev)); - struct fnic *fnic = lport_priv(lp); + struct fnic *fnic = + *((struct fnic **) shost_priv(class_to_shost(dev))); return sysfs_emit(buf, "%s\n", fnic_state_str[fnic->state]); } @@ -26,9 +26,13 @@ static ssize_t fnic_show_drv_version(struct device *dev, static ssize_t fnic_show_link_state(struct device *dev, struct device_attribute *attr, char *buf) { - struct fc_lport *lp = shost_priv(class_to_shost(dev)); + struct fnic *fnic = + *((struct fnic **) shost_priv(class_to_shost(dev))); - return sysfs_emit(buf, "%s\n", (lp->link_up) ?

Port channel RSCN is a Cisco vendor specific RSCN event. It is applicable only to Cisco UCS fabrics. If there's a change in the port channel configuration, an RCSN is sent to fnic. This is used to serially reset the scsi initiator fnics so that there's no all paths down scenario. The affected fnics are added to a list that are reset with a small time gap between them.
