[PATCH 4/4] drbd: switch from genl_magic macros to YNL-generated code

Christoph Böhmwalder
2026-04-07T17:34:17Z

Replace the genl_magic multi-include macro system with proper YNL
generation.

The bulk of the changes are mechanical renames to fit the generator
naming conventions:
- Handler functions: drbd_adm_* -> drbd_nl_*_doit/dumpit
- GENL_MAGIC_VERSION -> DRBD_FAMILY_VERSION
- GENL_MAGIC_FAMILY_HDRSZ -> sizeof(struct drbd_genlmsghdr)
- drbd_genl_family -> drbd_nl_family
- Attribute IDs: T_* -> DRBD_A_*

Remove the nested_attr_tb static global buffer and move to a per-call
allocation approach: each deserialization manages its own nested
attribute table. This will be needed anyway when we eventually move to
parallel_ops, and it's actually simpler to generate, so make this move
now.

Replace the functionality of the "sensitive" flag: this was only used
by a single field (shared_secret), open-code redaction logic for that
locally.

Also replace the "invariant" flag: this only had a couple of users, and
those basically never change. Hard code the check directly inline.

Define the genl_family struct manually in drbd_nl.c; this is not
emitted by the generator for genetlink-legacy families.

Also replace a couple of drbd-specific wrappers (nla_put_u64_0pad,
drbd_nla_find_nested) and replace by standard kernel functions while
we're at it.

Finally, completely remove the genl_magic system; DRBD was its only
user.

- *
- * sequence of netlink attributes:
- * I chose to have all "top level" attributes NLA_NESTED,
- * corresponding to some real struct.
- * So we have a sequence of |tla, len|<nested nla sequence>
- *
- * nested nla sequence:
- * may be empty, or contain a sequence of netlink attributes
- * representing the struct fields.
- *
- * The tag number of any field (regardless of containing struct)
- * will be available as T_ ## field_name,
- * so you cannot have the same field name in two differnt structs.
- *
- * The tag numbers themselves are per struct, though,
- * so should always begin at 1 (not 0, that is the special "NLA_UNSPEC" type,
- * which we won't use here).
- * The tag numbers are used as index in the respective nla_policy array.
- *
- * GENL_struct(tag_name, tag_number, struct name, struct fields) - struct and policy
- * genl_magic_struct.h
- * generates the struct declaration,
- * generates an entry in the tla enum,
- * genl_magic_func.h
- * generates an entry in the static tla policy
- * with .type = NLA_NESTED
- * generates the static <struct_name>_nl_policy definition,

- * tla list: the list of expected top level attributes,
- * for documentation and sanity checking.
- *
- * GENL_op(op_name, op_num, flags and handler, tla list) - "genl operations"
- * These are requests from userspace.
- *
- * _op and _notification share the same "number space",
- * op_nr will be assigned to "genlmsghdr->cmd"
- *
- * genl_magic_struct.h
- * generates an entry in the genl_ops enum,
