treewide: Replace kmalloc with kmalloc_obj for non-scalar types

2026-02-21T09:02:28+00:00

This is the result of running the Coccinelle script from scripts/coccinelle/api/kmalloc_objs.cocci. The script is designed to avoid scalar types (which need careful case-by-case checking), and instead replace kmalloc-family calls that allocate struct or union object instances: Single allocations: kmalloc(sizeof(TYPE), ...) are replaced with: kmalloc_obj(TYPE, ...) Array allocations: kmalloc_array(COUNT, sizeof(TYPE), ...) are replaced with: kmalloc_objs(TYPE, COUNT, ...) Flex array allocations: kmalloc(struct_size(PTR, FAM, COUNT), ...) are replaced with: kmalloc_flex(*PTR, FAM, COUNT, ...) (where TYPE may also be *VAR) The resulting allocations no longer return "void *", instead returning "TYPE *". Signed-off-by: Kees Cook

scsi: lpfc: Add support for reporting encryption events

2025-12-17T02:56:48+00:00

Support logging encryption events in both point-to-point and fabric topologies. A new LOG_ENCRYPTION flag is defined for reporting encryption related events for HBAs that support the FEDIF feature. Encryption information is stored in each NDLP object, which is determined during the discovery stage after PLOGI completes. For reporting encryption information to upper layers, the .get_fc_rport_enc_info routine is implemented in lpfc_get_enc_info(). This allows encryption status to be reported through fc_remote_ports sysfs. Debugfs is also updated to report encryption information for all NDLP objects.

scsi: lpfc: Convert debugfs directory counts from atomic to unsigned int

2025-09-17T02:20:00+00:00

Atomicity is not necessary for debugfs directory accounting because vport deletion and creation is already serialized. Creation has always been serialized through sysfs. Deletion is serialized via walking the lpfc_create_vport_work_array and calling fc_vport_terminate one-by-one for each NPIV port.

scsi: lpfc: Clean up extraneous phba dentries

2025-09-17T02:20:00+00:00

Because debugfs_remove recursively removes debugfs entries, the lpfc_debugfs_terminate routine is updated to remove only the parent/root debugfs directories. As such, there no longer is a need to keep track of each individual debugfs entry so clean up the unused phba dentries.

scsi: lpfc: Use switch case statements in DIF debugfs handlers

2025-09-17T02:20:00+00:00

With the introduction of aux numbers for debugfs entries, there's no need to use the if-else-if clause based on debugfs entry pointers. Update both the lpfc_debugfs_dif_err_read and lpfc_debugfs_dif_err_write routines to use switch case based on aux instead.

scsi: lpfc: Fix memory leak when nvmeio_trc debugfs entry is used

2025-09-17T02:20:00+00:00

Right after phba->nvmeio_trc is kzalloc'ed, phba->nvmeio_trc is set to NULL and the memory reference to free the kzalloc'ed memory is lost. Remove the phba->nvmeio_trc NULL ptr assignment after kzalloc. phba->nvmeio_trc is freed in lpfc_debugfs_terminate.
