batman-adv: fix kmalloc_obj redefinition on stable 6.18.33+

2026-05-27T07:59:16Z

Linux 6.18.33 stable backported kmalloc_obj/kmalloc_objs/kzalloc_obj, causing a redefinition conflict with compat-hacks.h which also defines these for kernels before 7.0.0. Exclude the 6.18.33-6.18.x stable range from the backport definitions. Signed-off-by: Janusz Dziedzic

batman-adv: fix build against Linux 6.18

2026-04-08T20:42:41Z

The EXTRA_CFLAGS for batman-adv were not applied with Linux 6.18. As result, C files for a specific features were build but the datastructures were missing the members for this specific feature. This can be avoided by switching to a more modern way of setting up the make command (like in this case "mt76"). Besides simplifying and cleaning up the code, it is now also directly providing the CONFIG preprocessor variables as part of NOSTDINC_FLAGS. This works on the current kernel versions 6.12 (default) and 6.18 (testing). Signed-off-by: Sven Eckelmann

batman-adv: update to version 2026.1

2026-04-08T12:12:50Z

* support latest kernels (5.10 - 7.1) * coding style cleanups and refactoring * bugs squashed: - reject oversized global TT response buffers - avoid OGM aggregation when skb tailroom is insufficient - prevent freed backbones when dumping BLA claims Signed-off-by: Sven Eckelmann

batman-adv: drop kmod-lib-crc32c on newer kernels

batman-adv: improve batadv_vlan.sh for LuCI

2026-03-18T12:50:06Z

Apply ap_isolation default value '0' if option ap_isolation is not present in the batadv_vlan interface configuration. Default value '0' should be applied for the use case where "option ap_isolation '1'" was present, is removed, and 'service network reload' is executed. This is required for proper LuCI integration, because if an option is set to the default value, LuCI removes the option. Also take into account $INCLUDE_ONLY as in other /lib/netifd/proto scripts and as recommended in the guide at: https://openwrt.org/docs/guide-developer/network-scripting Signed-off-by: Bastiaan Stougie

batman-adv: drop kmod-lib-crc32c on newer kernels

2026-03-03T19:24:14Z

This patch makes the dependency on kmod-lib-crc32c for the batman-adv package conditional: it is only required for Linux kernel 6.12. For kernel 6.18 and newer, the dependency is no longer needed. This prevents installing unnecessary modules on newer kernels. Signed-off-by: Mieczyslaw Nalewaj

batman-adv: update to version 2026.0

2026-02-24T16:39:03Z

* support latest kernels (5.10 - 7.0) * bugs squashed: - fix double-rtnl_lock ELP metric worker Signed-off-by: Sven Eckelmann

batman-adv: drop support for kernels < 6.12

2025-12-20T18:24:46Z

OpenWrt only supports Linux 6.12 at the moment. It is no longer necessary to support older versions of the kernel. Signed-off-by: Sven Eckelmann

batman-adv: update to version 2025.5
