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

vdpa: introduce map ops

2025-10-01T11:24:55+00:00

Virtio core allows the transport to provide device or transport specific mapping functions. This patch adds this support to vDPA. We can simply do this by allowing the vDPA parent to register a virtio_map_ops.

vdpa: solidrun: Replace deprecated PCI functions

2025-01-27T14:39:25+00:00

The PCI functions pcim_iomap_regions() pcim_iounmap_regions() pcim_iomap_table() have been deprecated by the PCI subsystem. Replace these functions with their successors pcim_iomap_region() and pcim_iounmap_region().

vdpa: solidrun: Fix UB bug with devres

2024-11-06T09:40:07+00:00

In psnet_open_pf_bar() and snet_open_vf_bar() a string later passed to pcim_iomap_regions() is placed on the stack. Neither pcim_iomap_regions() nor the functions it calls copy that string. Should the string later ever be used, this, consequently, causes undefined behavior since the stack frame will by then have disappeared. Fix the bug by allocating the strings on the heap through devm_kasprintf(). Cc: stable@vger.kernel.org # v6.3 Fixes: 51a8f9d7f587 ("virtio: vdpa: new SolidNET DPU driver.")
