However, instead of using strncpy(dest, src, LEN-1) we can opt for strscpy(dest, src, sizeof(dest)) which will result in NUL-termination as well. It should be noted that the entire chap_table is zero-allocated so the NUL-padding provided by strncpy is not needed. While here, I noticed that MIN_CHAP_SECRET_LEN was not used anywhere. Since strscpy gives us the number of bytes copied into the destination buffer (or an -E2BIG) we can check both for an error during copying and also for a non-length compliant secret. Add a new jump label so we can properly clean up our chap_table should we have to abort due to bad secret. The third instance in this file involves some more peculiar handling of strings: | uint32_t mbox_cmd[MBOX_REG_COUNT]; | ... | memset(&mbox_cmd, 0, sizeof(mbox_cmd)); | ... | mbox_cmd[0] = MBOX_CMD_SET_PARAM; | if (param == SET_DRVR_VERSION) { | mbox_cmd[1] = SET_DRVR_VERSION; | strncpy((char *)&mbox_cmd[2], QLA4XXX_DRIVER_VERSION, | MAX_DRVR_VER_LEN - 1); mbox_cmd has a size of 8: | #define MBOX_REG_COUNT 8 ... and its type width is 4 bytes. Hence, we have 32 bytes to work with here. The first 4 bytes are used as a flag for the MBOX_CMD_SET_PARAM. The next 4 bytes are used for SET_DRVR_VERSION. We now have 32-8=24 bytes remaining -- which thankfully is what MAX_DRVR_VER_LEN is equal to | #define MAX_DRVR_VER_LEN 24 ... and the thing we're copying into this pseudo-string buffer is | #define QLA4XXX_DRIVER_VERSION "5.04.00-k6" ... which is great because its less than 24 bytes (therefore we aren't truncating the source). All to say, there's no bug in the existing implementation (yay!) but we can clean the code up a bit by using strscpy(). In ql4_os.c, there aren't any strncpy() uses to replace but there are some existing strscpy() calls that could be made more idiomatic. Where possible, use strscpy(dest, src, sizeof(dest)). Note that chap_rec->password has a size of ISCSI_CHAP_AUTH_SECRET_MAX_LEN | #define ISCSI_CHAP_AUTH_SECRET_MAX_LEN 256 ... while the current strscpy usage uses QL4_CHAP_MAX_SECRET_LEN | #define QL4_CHAP_MAX_SECRET_LEN 100 ... however since chap_table->secret was set and bounded properly in its string assignment its probably safe here to switch over to sizeof(). | struct iscsi_chap_rec { ... | char username[ISCSI_CHAP_AUTH_NAME_MAX_LEN]; | uint8_t password[ISCSI_CHAP_AUTH_SECRET_MAX_LEN]; ... | }; | strscpy(chap_rec->password, chap_table->secret, | QL4_CHAP_MAX_SECRET_LEN); Reviewed-by: Kees Cook Signed-off-by: Justin Stitt Link: https://lore.kernel.org/r/20240305-strncpy-drivers-scsi-mpi3mr-mpi3mr_fw-c-v3-4-5b78a13ff984@google.com Signed-off-by: Martin K.

Similar to how a standard template is used in libata with __ATA_BASE_SHT, create a standard template in LIBSAS_SHT_BASE. Don't set a default for max_sectors at SCSI_DEFAULT_MAX_SECTORS, as scsi_host_alloc() will default to this value automatically.

This commit introduces the ncq_prio_supported and ncq_prio_enable sysfs device attributes to discover and control the use of this features, similarly to libata. However, libata publicly declares these device attributes and export them for use in ATA low level drivers. This leads to a compilation error when libsas and libata are built-in due to the double definition: ld: drivers/ata/libata-sata.o:/home/Linux/scsi/drivers/ata/libata-sata.c:900: multiple definition of `dev_attr_ncq_prio_supported'; drivers/scsi/libsas/sas_ata.o:/home/Linux/scsi/drivers/scsi/libsas/sas_ata.c:984: first defined here ld: drivers/ata/libata-sata.o:/home/Linux/scsi/drivers/ata/libata-sata.c:1026: multiple definition of `dev_attr_ncq_prio_enable'; drivers/scsi/libsas/sas_ata.o:/home/Linux/scsi/drivers/scsi/libsas/sas_ata.c:1022: first defined here Resolve this problem by directly declaring the libsas attributes instead of using the DEVICE_ATTR() macro. And for good measure, the device attribute variables are also renamed.

It is vanishingly unlikely that even there are out there platforms that uses earlier host controllers, let alone that those ancient platforms will ever run a V6.10 kernel. To be extra cautious, leave out removal of UFSHCI 2.0 support from this patch, and just remove support of host controllers prior to UFS2.0. This patch removes some legacy tuning calls that no longer apply.

This fixes 7 kernel-doc warnings. - In struct fc_rport_priv, change 'event_callback' to 'lld_event_callback' to match the struct member name. - In struct fc_fcp_pkt, add a description for 'timer_delay' to eliminate one kernel-doc warning. - Add return value notation for 3 functions. This fixes 3 kernel-doc warnings. There are still 12 warnings for struct members not described in struct fc_rport_priv and struct fc_lport, e.g: libfc.h:218: warning: Function parameter or struct member 'event' not described in 'fc_rport_priv' libfc.h:760: warning: Function parameter or struct member 'vlan' not described in 'fc_lport' Warnings that are fixed in this patch: libfc.h:75: warning: Enum value 'LPORT_ST_RNN_ID' not described in enum 'fc_lport_state' libfc.h:75: warning: Enum value 'LPORT_ST_RSNN_NN' not described in enum 'fc_lport_state' libfc.h:75: warning: Enum value 'LPORT_ST_RSPN_ID' not described in enum 'fc_lport_state' libfc.h:75: warning: Enum value 'LPORT_ST_RPA' not described in enum 'fc_lport_state' libfc.h:75: warning: Enum value 'LPORT_ST_DHBA' not described in enum 'fc_lport_state' libfc.h:75: warning: Enum value 'LPORT_ST_DPRT' not described in enum 'fc_lport_state' libfc.h:75: warning: Excess enum value 'LPORT_ST_RPN_ID' description in 'fc_lport_state' libfc.h:218: warning: Excess struct member 'event_callback' description in 'fc_rport_priv' libfc.h:793: warning: No description found for return value of 'fc_lport_test_ready' libfc.h:835: warning: No description found for return value of 'fc_lport_init_stats' libfc.h:856: warning: No description found for return value of 'lport_priv' Signed-off-by: Randy Dunlap Link: https://lore.kernel.org/r/20240424050038.31403-1-rdunlap@infradead.org Cc: Hannes Reinecke Cc: James E.J.

Note we make use of the previously added EXYNOS_UFS_OPT_UFSPR_SECURE option, to skip initialisation of UFSPR registers as these are only accessible via SMC call. EXYNOS_UFS_OPT_TIMER_TICK_SELECT option is also set to select tick source. This has been done so as not to effect any existing platforms. DBG_OPTION_SUITE on gs101 has different address offsets to other SoCs so these register offsets now come from uic_attr struct.

Changes to accommodate 32 byte CDBs include: - Updating various size fields to allow for the larger 32 byte CDB. - Starting the FCP command payload at an earlier offset in WQE submission to fit the 32 byte CDB. - Redefining relevant structs to __le32/__be32 data types for proper cpu endianness macro usage.
