It does this while still being able to fall back to the old debugfs tables on kernels which don't support the new generic netlink family. Something similar should be done in the future for the settings which are currently part of sysfs. But we can already see that the current integration of netlink in batctl only done in a single file - netlink.c But this file is already starting to be so big that working with it is rather cumbersome. So as first steps: * restructure command registration * move commands in separate files (which should store their actual implementation) * add a new helper command to receive multicast group messages from the kernel More things will follow in the future. Changes: v3: * correctly split ap_isolation and bonding patch * fix copyright headers for new files * move more routing_algo specific code to its command specific file * fix build problems with musl in OpenWrt 18.06 * switch Makefile's OBJ + OBJ_BISECT to obj-y and obj-n * add way to "freely" disable some commands for size optimization reasons - it is for example now possible to reduce the size of the batctl on mips_24kc_musl from 64604 bytes to 14252 bytes when only the interface commands are required (I know, stupid example) - the binary to generate the debug tables output for the same architectur used 26988 bytes v2: * Add missing orig_interval.c Kind regards, Sven Sven Eckelmann (42): batctl: Drop unused define SOCKET_PATH_FMT batctl: Use common code organization for statistics batctl: Drop legacy vis_* related warning messages batctl: Move loglevel command to separate file batctl: Move log command to separate file batctl: Move gw_mode command to separate file batctl: Move routing_algo command to separate file batctl: Rename tp_meter to throughputmeter batctl: Introduce datastructure for subcommands batctl: Add per command flags batctl: Use command structure for remaining subcommands batctl: Use getopt to parse main options batctl: Store usage line next to command batctl: Prepare command infrastructure for shared functions batctl: Add type to command to structure usage output batctl: Convert debug table to command infrastructure batctl: Convert sysfs settings to command infrastructure batctl: Move backbonetable debug table to own file batctl: Move claimtable debug table to own file batctl: Move dat_cache debug table to own file batctl: Move gateways debug table to own file batctl: Move mcast_flags debug table to own file batctl: Move nc_nodes debug table to own file batctl: Move neighbors debug table to own file batctl: Move originators debug table to own file batctl: Move transglobal debug table to own file batctl: Move translocal debug table to own file batctl: Move aggregation setting to own file batctl: Move ap_isolation setting to own file batctl: Move bonding setting to own file batctl: Move bridge_loop_avoidance setting to own file batctl: Move distributed_arp_table setting to own file batctl: Move fragmentation setting to own file batctl: Move isolation_mark setting to own file batctl: Move multicast_mode setting to own file batctl: Move network_coding setting to own file batctl: Move orig_interval setting to own file batctl: Use external netlink socket for debug tables batctl: Move routing_algo specific code it command source file batctl: Add command to monitor for netlink events batctl: Simplify enabling for bisect_iv subcommand batctl: Allow to enable/disable subcommands Makefile | 91 ++- translate.h => aggregation.c | 15 +- ap_isolation.c | 33 + backbonetable.c | 126 ++++ bisect_iv.c | 6 +- bisect_iv.h | 4 - traceroute.h => bonding.c | 15 +- bridge_loop_avoidance.c | 33 + claimtable.c | 131 ++++ dat_cache.c | 147 +++++ debug.c | 218 +------ debug.h | 38 +- distributed_arp_table.c | 33 + event.c | 246 ++++++++ ping.h => fragmentation.c | 15 +- functions.c | 28 +- functions.h | 1 - gateways.c | 175 +++++ gw_mode.c | 171 +++++ interface.c | 23 +- ioctl.h | 28 - isolation_mark.c | 35 + log.c | 73 +++ loglevel.c | 147 +++++ main.c | 274 ++++---- main.h | 65 +- man/batctl.8 | 4 + mcast_flags.c | 180 ++++++ multicast_mode.c | 33 + interface.h => nc_nodes.c | 14 +- neighbors.c | 142 +++++ netlink.c | 1332 ++++----------------------------------- netlink.h | 55 +- network_coding.c | 33 + orig_interval.c | 35 + originators.c | 228 +++++++ ping.c | 10 +- routing_algo.c | 263 ++++++++ ioctl.c => statistics.c | 10 +- sys.c | 432 +------------ sys.h | 39 +- tcpdump.c | 5 +- tcpdump.h | 2 - tp_meter.c => throughputmeter.c | 10 +- tp_meter.h | 28 - traceroute.c | 10 +- transglobal.c | 162 +++++ translate.c | 8 +- translocal.c | 158 +++++ 49 files changed, 3156 insertions(+), 2208 deletions(-) rename translate.h => aggregation.c (67%) create mode 100644 ap_isolation.c create mode 100644 backbonetable.c rename traceroute.h => bonding.c (68%) create mode 100644 bridge_loop_avoidance.c create mode 100644 claimtable.c create mode 100644 dat_cache.c create mode 100644 distributed_arp_table.c create mode 100644 event.c rename ping.h => fragmentation.c (67%) create mode 100644 gateways.c create mode 100644 gw_mode.c delete mode 100644 ioctl.h create mode 100644 isolation_mark.c create mode 100644 log.c create mode 100644 loglevel.c create mode 100644 mcast_flags.c create mode 100644 multicast_mode.c rename interface.h => nc_nodes.c (73%) create mode 100644 neighbors.c create mode 100644 network_coding.c create mode 100644 orig_interval.c create mode 100644 originators.c create mode 100644 routing_algo.c rename ioctl.c => statistics.c (90%) rename tp_meter.c => throughputmeter.c (97%) delete mode 100644 tp_meter.h create mode 100644 transglobal.c create mode 100644 translocal.c
