Add a check in lpfc_poll_eratt() when the driver is unloading. There is no point to check for error attention events if the driver is rmmod'ed.

2023-11-15scsi: elx: libefc: Replace deprecated strncpy() with strscpy_pad()/memcpy()Justin Stitt1-6/+6
strncpy() is deprecated for use on NUL-terminated destination strings [1] and as such we should prefer more robust and less ambiguous string interfaces. To keep node->current_state_name and node->prev_state_name NUL-padded and NUL-terminated let's use strscpy_pad() as this implicitly provides both. For the swap between the two, a simple memcpy() will suffice.

strncpy() is deprecated for use on NUL-terminated destination strings [1] and as such we should prefer more robust and less ambiguous string interfaces. 'hw' is kzalloc'd just before this string assignment: | hw = kzalloc(sizeof(struct csio_hw), GFP_KERNEL); ... which means any NUL-padding is redundant. Since CSIO_DRV_VERSION is a small string literal (smaller than sizeof(dest)): ... there is functionally no change in this swap from strncpy() to strscpy(). Nonetheless, let's make the change for robustness' sake -- as it will ensure that drv_version is _always_ NUL-terminated.

strncpy() is deprecated for use on NUL-terminated destination strings [1] and as such we should prefer more robust and less ambiguous string interfaces. These labels get copied out to the user so lets make sure they are NUL-terminated and NUL-padded. vparams is already memset to 0 so we don't need to do any NUL-padding (like what strncpy() is doing). Considering the above, a suitable replacement is strscpy() [2] due to the fact that it guarantees NUL-termination on the destination buffer without unnecessarily NUL-padding. Let's also opt to use the more idiomatic strscpy() usage of: (dest, src, sizeof(dest)) as this more closely ties the destination buffer to the length.

strncpy() is deprecated for use on NUL-terminated destination strings [1] and as such we should prefer more robust and less ambiguous string interfaces. We expect hba->chip_num to be NUL-terminated based on its usage with format strings: snprintf(fc_host_symbolic_name(lport->host), 256, "%s (QLogic %s) v%s over %s", BNX2FC_NAME, hba->chip_num, BNX2FC_VERSION, interface->netdev->name); Moreover, NUL-padding is not required as hba is zero-allocated from its callsite: hba = kzalloc(sizeof(*hba), GFP_KERNEL); Considering the above, a suitable replacement is strscpy() [2] due to the fact that it guarantees NUL-termination on the destination buffer without unnecessarily NUL-padding. Regarding stats_addr->version, I've opted to also use strscpy() instead of strscpy_pad() as I typically see these XYZ_get_strings() pass zero-allocated data. I couldn't track all of where bnx2fc_ulp_get_stats() is used and if required, we could opt for strscpy_pad().

2023-11-15scsi: 3w-sas: Replace deprecated strncpy() with strscpy()Justin Stitt1-1/+2
strncpy() is deprecated for use on NUL-terminated destination strings [1] and as such we should prefer more robust and less ambiguous string interfaces. This pattern of strncpy(dest, src, strlen(src)) is extremely bug-prone. This pattern basically never results in NUL-terminated destination strings unless `dest` was zero-initialized. The current implementation may be accidentally correct as tw_dev is zero-allocated via: host = scsi_host_alloc(&driver_template, sizeof(TW_Device_Extension)); ... tw_dev = shost_priv(host); ... wherein scsi_host_alloc() zero-allocates host: shost = kzalloc(sizeof(struct Scsi_Host) + privsize, GFP_KERNEL); Also, further suggesting this change is worthwhile is another strscpy() usage in 3w-9xxx.c: strscpy(tw_dev->tw_compat_info.driver_version, TW_DRIVER_VERSION, sizeof(tw_dev->tw_compat_info.driver_version)); Considering the above, a suitable replacement is strscpy() [2] due to the fact that it guarantees NUL-termination on the destination buffer without unnecessarily NUL-padding. Let's not be accidentally correct, let's be definitely correct.

2023-11-15scsi: mpt3sas: Remove the iounit_pg8 member of the per-adapter structJames Seo2-5/+4
The per-adapter struct (struct MPT3SAS_ADAPTER) contains a MPI2_CONFIG_PAGE_IO_UNIT_8 (Mpi2IOUnitPage8_t) iounit_pg8 member that is populated by mpt3sas_base.c:_base_static_config_pages(). As the name of that function indicates, the iounit_pg8 member represents a static configuration page data structure that rarely changes, and is among several such static config pages that are currently being fetched once per adapter per init (or reset) and copied to the per-adapter struct for later use. However, unlike the other static config pages, the iounit_pg8 member is never actually used outside of _base_static_config_pages(). Also, Mpi2IOUnitPage8_t has a flexible array member, making its presence in the _middle_ of the per-adapter struct rather strange.

2023-11-08scsi: sd: Fix sshdr use in sd_suspend_common()Mike Christie1-30/+23
If scsi_execute_cmd() returns < 0, it doesn't initialize the sshdr, so we shouldn't access the sshdr. If it returns 0, then the cmd executed successfully, so there is no need to check the sshdr. sd_sync_cache() will only access the sshdr if it's been setup because it calls scsi_status_is_check_condition() before accessing it. However, the sd_sync_cache() caller, sd_suspend_common(), does not check. sd_suspend_common() is only checking for ILLEGAL_REQUEST which it's using to determine if the command is supported. If it's not it just ignores the error. So to fix its sshdr use this patch just moves that check to sd_sync_cache() where it converts ILLEGAL_REQUEST to success/0. sd_suspend_common() was ignoring that error and sd_shutdown() doesn't check for errors so there will be no behavior changes.

2023-11-08scsi: qla2xxx: Fix system crash due to bad pointer accessQuinn Tran1-2/+10
User experiences system crash when running AER error injection. The perturbation causes the abort-all-I/O path to trigger. The driver assumes all I/O on this path is FCP only. If there is both NVMe & FCP traffic, a system crash happens. Add additional check to see if I/O is FCP or not before access.

Joel Granados has been doing all this work. On the v6.6 kernel we got the major infrastructure changes required to support this. For v6.7-rc1 we have all arch/ and drivers/ modified to remove the sentinel. Both arch and driver changes have been on linux-next for a bit less than a month. It is worth re-iterating the value: - this helps reduce the overall build time size of the kernel and run time memory consumed by the kernel by about ~64 bytes per array - the extra 64-byte penalty is no longer inncurred now when we move sysctls out from kernel/sysctl.c to their own files For v6.8-rc1 expect removal of all the sentinels and also then the unneeded check for procname == NULL. The last two patches are fixes recently merged by Krister Johansen which allow us again to use softlockup_panic early on boot. This used to work but the alias work broke it.

git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull x86 core updates from Thomas Gleixner: - Limit the hardcoded topology quirk for Hygon CPUs to those which have a model ID less than 4. The newer models have the topology CPUID leaf 0xB correctly implemented and are not affected. - Make SMT control more robust against enumeration failures SMT control was added to allow controlling SMT at boottime or runtime. The primary purpose was to provide a simple mechanism to disable SMT in the light of speculation attack vectors. It turned out that the code is sensible to enumeration failures and worked only by chance for XEN/PV. XEN/PV has no real APIC enumeration which means the primary thread mask is not set up correctly. By chance a XEN/PV boot ends up with smp_num_siblings == 2, which makes the hotplug control stay at its default value "enabled". So the mask is never evaluated. The ongoing rework of the topology evaluation caused XEN/PV to end up with smp_num_siblings == 1, which sets the SMT control to "not supported" and the empty primary thread mask causes the hotplug core to deny the bringup of the APS. Make the decision logic more robust and take 'not supported' and 'not implemented' into account for the decision whether a CPU should be booted or not. - Fake primary thread mask for XEN/PV Pretend that all XEN/PV vCPUs are primary threads, which makes the usage of the primary thread mask valid on XEN/PV. That is consistent with because all of the topology information on XEN/PV is fake or even non-existent. - Encapsulate topology information in cpuinfo_x86 Move the randomly scattered topology data into a separate data structure for readability and as a preparatory step for the topology evaluation overhaul. - Consolidate APIC ID data type to u32 It's fixed width hardware data and not randomly u16, int, unsigned long or whatever developers decided to use. - Cure the abuse of cpuinfo for persisting logical IDs. Per CPU cpuinfo is used to persist the logical package and die IDs. That's really not the right place simply because cpuinfo is subject to be reinitialized when a CPU goes through an offline/online cycle. Use separate per CPU data for the persisting to enable the further topology management rework. It will be removed once the new topology management is in place. - Provide a debug interface for inspecting topology information Useful in general and extremly helpful for validating the topology management rework in terms of correctness or "bug" compatibility. * tag 'x86-core-2023-10-29-v2' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (23 commits) x86/apic, x86/hyperv: Use u32 in hv_snp_boot_ap() too x86/cpu: Provide debug interface x86/cpu/topology: Cure the abuse of cpuinfo for persisting logical ids x86/apic: Use u32 for wakeup_secondary_cpu[_64]() x86/apic: Use u32 for [gs]et_apic_id() x86/apic: Use u32 for phys_pkg_id() x86/apic: Use u32 for cpu_present_to_apicid() x86/apic: Use u32 for check_apicid_used() x86/apic: Use u32 for APIC IDs in global data x86/apic: Use BAD_APICID consistently x86/cpu: Move cpu_l[l2]c_id into topology info x86/cpu: Move logical package and die IDs into topology info x86/cpu: Remove pointless evaluation of x86_coreid_bits x86/cpu: Move cu_id into topology info x86/cpu: Move cpu_core_id into topology info hwmon: (fam15h_power) Use topology_core_id() scsi: lpfc: Use topology_core_id() x86/cpu: Move cpu_die_id into topology info x86/cpu: Move phys_proc_id into topology info x86/cpu: Encapsulate topology information in cpuinfo_x86 ...

2023-10-27scsi: sd: Introduce manage_shutdown device flagDamien Le Moal1-3/+36
Commit aa3998dbeb3a ("ata: libata-scsi: Disable scsi device manage_system_start_stop") change setting the manage_system_start_stop flag to false for libata managed disks to enable libata internal management of disk suspend/resume. However, a side effect of this change is that on system shutdown, disks are no longer being stopped (set to standby mode with the heads unloaded). While this is not a critical issue, this unclean shutdown is not recommended and shows up with increased smart counters (e.g. the unexpected power loss counter "Unexpect_Power_Loss_Ct"). Instead of defining a shutdown driver method for all ATA adapter drivers (not all of them define that operation), this patch resolves this issue by further refining the sd driver start/stop control of disks using the new flag manage_shutdown. If this new flag is set to true by a low level driver, the function sd_shutdown() will issue a START STOP UNIT command with the start argument set to 0 when a disk needs to be powered off (suspended) on system power off, that is, when system_state is equal to SYSTEM_POWER_OFF. Similarly to the other manage_xxx flags, the new manage_shutdown flag is exposed through sysfs as a read-write device attribute. To avoid any confusion between manage_shutdown and manage_system_start_stop, the comments describing these flags in include/scsi/scsi.h are also improved.

2023-10-16scsi: qla2xxx: Fix double free of dsd_list during driver loadQuinn Tran1-1/+1
On driver load, scsi_add_host() can fail. This triggers the free path to call qla2x00_mem_free() multiple times. This causes NULL pointer access of ha->base_qpair. Add check before access.

2023-10-16scsi: core: Handle depopulation and restoration in progressDouglas Gilbert2-0/+5
The default handling of the NOT READY sense key is to wait for the device to become ready. The "wait" is assumed to be relatively short. However there is a sub-class of NOT READY that have the "... in progress" phrase in their additional sense code and these can take much longer. Following on from commit 505aa4b6a883 ("scsi: sd: Defer spinning up drive while SANITIZE is in progress") we now have element depopulation and restoration that can take a long time. For example, over 24 hours for a 20 TB, 7200 rpm hard disk to depopulate 1 of its 20 elements. Add handling of ASC/ASCQ: 0x4,0x24 (depopulation in progress) and ASC/ASCQ: 0x4,0x25 (depopulation restoration in progress) to sd.c . The scsi_lib.c has incomplete handling of these two messages, so complete it.
