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: aacraid: struct {user,}sgmap{,64,raw}: Replace 1-element arrays with flexible arrays

2024-08-03T01:38:08+00:00

Replace the deprecated[1] use of 1-element arrays in struct sgmap, struct sgmap64, struct sgmapraw, struct user_sgmap, and struct user_sgmap64 with modern flexible arrays. Additionally remove struct user_sgmapraw as it is unused. The resulting binary output differences from this change are limited only to stack space consumption of the smaller "srbu" variable in aac_issue_safw_bmic_identify() and aac_get_safw_ciss_luns(), as well as the smaller associated pair of memcpy()s in aac_send_safw_bmic_cmd(). Artificially growing the size of srbu back to its prior size removes all binary differences[2]. As an aside, after studying the aacraid driver code I wonder how aac_send_wellness_command() ever works. It is reporting a size 4 bytes too small for what it has constructed in memory in the DMA region: sgentry64 is size 12, whereas sgentry is size 8. Perhaps the hardware doesn't care. (Regardless, it is unchanged by this patch.)

scsi: core: Improve type safety of scsi_rescan_device()

2023-08-25T02:11:29+00:00

Most callers of scsi_rescan_device() have the scsi_device pointer readily available. Pass a struct scsi_device pointer to scsi_rescan_device() instead of a struct device pointer. This change prevents that a pointer to another struct device would be passed accidentally to scsi_rescan_device(). Remove the scsi_rescan_device() declaration from the scsi_priv.h header file since it duplicates the declaration in .

scsi: aacraid: Reply queue mapping to CPUs based on IRQ affinity

2023-06-15T01:13:40+00:00

Fix the I/O hang that arises because of the MSIx vector not having a mapped online CPU upon receiving completion. SCSI cmds take the blk_mq route, which is setup during init. Reserved cmds fetch the vector_no from mq_map after init is complete. Before init, they have to use 0 - as per the norm.
