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

net: phy: microchip_rds_ptp: add HW timestamp configuration reporting

The driver stores HW timestamping configuration and can technically report it. Add callback to do it. Reviewed-by: Kory Maincent Signed-off-by: Vadim Fedorenko Link: https://patch.msgid.link/20260106160723.3925872-5-vadim.fedorenko@linux.dev Signed-off-by: Jakub Kicinski

net: phy: microchip_rds_ptp: improve HW ts config logic

2026-01-09T02:13:12+00:00

The driver stores new HW timestamping configuration values unconditionally and may create inconsistency with what is actually configured in case of error. Improve the logic to store new values only once everything is configured.

net: ptp: introduce .supported_perout_flags to ptp_clock_info

2025-04-16T03:20:58+00:00

The PTP_PEROUT_REQUEST2 ioctl has gained support for flags specifying specific output behavior including PTP_PEROUT_ONE_SHOT, PTP_PEROUT_DUTY_CYCLE, PTP_PEROUT_PHASE. Driver authors are notorious for not checking the flags of the request. This results in misinterpreting the request, generating an output signal that does not match the requested value. It is anticipated that even more flags will be added in the future, resulting in even more broken requests. Expecting these issues to be caught during review or playing whack-a-mole after the fact is not a great solution. Instead, introduce the supported_perout_flags field in the ptp_clock_info structure. Update the core character device logic to explicitly reject any request which has a flag not on this list. This ensures that drivers must 'opt in' to the flags they support. Drivers which don't set the .supported_perout_flags field will not need to check that unsupported flags aren't passed, as the core takes care of this. Update the drivers which do support flags to set this new field. Note the following driver files set n_per_out to a non-zero value but did not check the flags at all: • drivers/ptp/ptp_clockmatrix.c • drivers/ptp/ptp_idt82p33.c • drivers/ptp/ptp_fc3.c • drivers/net/ethernet/ti/am65-cpts.c • drivers/net/ethernet/aquantia/atlantic/aq_ptp.c • drivers/net/ethernet/broadcom/bnxt/bnxt_ptp.c • drivers/net/dsa/sja1105/sja1105_ptp.c • drivers/net/ethernet/freescale/dpaa2/dpaa2-ptp.c • drivers/net/ethernet/mscc/ocelot_vsc7514.c • drivers/net/ethernet/intel/i40e/i40e_ptp.c Reviewed-by: Vadim Fedorenko Signed-off-by: Jacob Keller Reviewed-by: Kory Maincent Link: https://patch.msgid.link/20250414-jk-supported-perout-flags-v2-2-f6b17d15475c@intel.com Signed-off-by: Jakub Kicinski
