soc: fsl: qe: panic on ioremap() failure in qe_reset()

2026-04-04T16:52:09+00:00

When ioremap() fails in qe_reset(), the global pointer qe_immr remains NULL, leading to a subsequent NULL pointer dereference when the pointer is accessed. Since this happens early in the boot process, a failure to map a few bytes of I/O memory indicates a fatal error from which the system cannot recover. Follow the same pattern as qe_sdma_init() and panic immediately when ioremap() fails. This avoids a silent NULL pointer dereference later and makes the error explicit.

soc: fsl: qe_ports_ic: switch to irq_domain_create_linear()

2026-03-25T10:24:07+00:00

irq_domain_add_linear() is about to be removed, replace by the more generic irq_domain_create_linear(), see commit 42b8b16fe56c ("irqdomain: Drop irq_domain_add_*() functions") for details.

soc: fsl: guts: don't access of_root directly

Don't access of_root directly as it reduces the build test coverage for this driver with COMPILE_TEST=y and OF=n. Use existing helper functions to retrieve the relevant information.

Fix wrong variable used for error checking after devm_ioremap_resource() call. The function checks qmc->scc_pram instead of qmc->dpram, which could lead to incorrect error handling.

soc: fsl: qbman: fix race condition in qman_destroy_fq

2026-02-23T13:49:27+00:00

When QMAN_FQ_FLAG_DYNAMIC_FQID is set, there's a race condition between fq_table[fq->idx] state and freeing/allocating from the pool and WARN_ON(fq_table[fq->idx]) in qman_create_fq() gets triggered. Indeed, we can have: Thread A Thread B qman_destroy_fq() qman_create_fq() qman_release_fqid() qman_shutdown_fq() gen_pool_free() -- At this point, the fqid is available again -- qman_alloc_fqid() -- so, we can get the just-freed fqid in thread B -- fq->fqid = fqid; fq->idx = fqid * 2; WARN_ON(fq_table[fq->idx]); fq_table[fq->idx] = fq; fq_table[fq->idx] = NULL; And adding some logs between qman_release_fqid() and fq_table[fq->idx] = NULL makes the WARN_ON() trigger a lot more. To prevent that, ensure that fq_table[fq->idx] is set to NULL before gen_pool_free() is called by using smp_wmb().

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
