ethtool: tsconfig: fix missing ethnl_ops_complete()

2026-06-09T10:32:26+00:00

[ Upstream commit 6386bd772de64e6760306eb91c7e86163af6c22f ] tsconfig_prepare_data() calls ethnl_ops_begin(), we need to call ethnl_ops_complete() before returning the error.

ethtool: tsconfig: fix reply error handling

2026-06-09T10:32:25+00:00

[ Upstream commit a888bbd43940cada72f7686337741ce86d1cf869 ] A couple of trivial bugs in error handling in tsconfig_send_reply(). If we failed to allocate rskb we need to set the error. If we did allocate it but failed to send it - we need to remember to free it.

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: ethtool: tsconfig: set command must provide a reply

2025-09-24T00:13:05+00:00

Timestamping configuration through ethtool has inconsistent behavior of skipping the reply for set command if configuration was not changed. Fix it be providing reply in any case.

net: ethtool: tsconfig: Fix netlink type of hwtstamp flags

2025-02-07T00:35:21+00:00

Fix the netlink type for hardware timestamp flags, which are represented as a bitset of flags. Although only one flag is supported currently, the correct netlink bitset type should be used instead of u32 to keep consistency with other fields. Address this by adding a new named string set description for the hwtstamp flag structure. The code has been introduced in the current release so the uAPI change is still okay.

net: ethtool: Add support for tsconfig command to get/set hwtstamp config

Introduce support for ETHTOOL_MSG_TSCONFIG_GET/SET ethtool netlink socket to read and configure hwtstamp configuration of a PHC provider. Note that simultaneous hwtstamp isn't supported; configuring a new one disables the previous setting. Signed-off-by: Kory Maincent Signed-off-by: David S. Miller
