netlink: clean up sockets, close files

2026-01-10T09:45:22Z

Sockets are handled for most usage paths, except for shutdown. Handle those at shutdown. Signed-off-by: Paul Donald Link: https://github.com/openwrt/odhcpd/pull/367 Signed-off-by: Álvaro Fernández Rojas

netlink: make it clearer that we're handling realloc correctly

2025-11-27T07:24:53Z

This doesn't really change the code, it just makes it clearer when grepping for realloc() that failure is handled correctly. Signed-off-by: David Härdeman Link: https://github.com/openwrt/odhcpd/pull/320 Signed-off-by: Álvaro Fernández Rojas

netlink: add netmask for IPv4

2025-11-27T07:24:02Z

Add a netmask member to struct odhcpd_ipaddr, this is mostly for convenience. Signed-off-by: David Härdeman Link: https://github.com/openwrt/odhcpd/pull/320 Signed-off-by: Álvaro Fernández Rojas

netlink: variable naming cleanup

2025-11-27T07:23:59Z

Correct some comments, use boolean where a boolean value is expected, rename more "struct odhcpd_ipaddr" variables to indicate that it is a struct odhcpd_ipaddr and indicate plural/IPv4/IPv6 in the variable names.

odhcpd: rename iface->addr4 -> iface->oaddrs4

2025-11-27T07:23:50Z

Rename iface->addr4 to iface->oaddrs4, to make it clearer from a cursory glance that this isn't e.g. "struct in_addr" addresses but a number of "struct odhcpd_ipaddr" addresses. At the same time, rename iface->addr4_len to iface->oaddrs4_cnt, to make it clear that this is a count and not e.g. an allocation length.

odhcpd: rename prefix -> prefix_len

2025-11-27T07:23:45Z

Change a bunch of places where a prefix length is stored as "prefix" to instead call the length "prefix_len", to make it clearer that it is not a prefix that is stored. Signed-off-by: David Härdeman Link: https://github.com/openwrt/odhcpd/pull/320 Signed-off-by: Álvaro Fernández Rojas

src: improve attributes

2025-11-17T07:24:50Z

- Properly guard odhcp6c.h attributes with `#ifndef` to avoid redefining them when including external headers. - Also convert the remaining __attribute__ usages to the custom declarations. - Consolidate custom declarations with _o_ prefix.

src: consolidate and improve fallthrough

2025-11-17T07:24:34Z

- Enable fallthrough warnings. - Use fallthrough attribute instead of comments. - Drop unneeded fallthroughs (no code between two case statements). Signed-off-by: Álvaro Fernández Rojas Link: https://github.com/openwrt/odhcpd/pull/307

netlink: fix typo in debug msg

2025-11-11T13:18:39Z

As noted by @CasperVector in #115, there's a typo in netlink.c, checking if true is true isn't very useful :) Signed-off-by: David Härdeman Link: https://github.com/openwrt/odhcpd/pull/305 Signed-off-by: Álvaro Fernández Rojas

src: fix whitespace issues

2025-11-11T11:46:15Z

- Remove double whitespaces. - Convert whitespace alignments to tabs. - Fix code comments using whitespaces. Signed-off-by: Álvaro Fernández Rojas
