Most commands have a separate file which is called like command itself.
They also tend to share the same function signature to make it easier to
use. Do the same for the ethtool statistics to make it easier to find.

The vis support code was removed with batman-adv 2014.0.0 (Linux 3.13). All
kernel versions with up to this version are EOL for a while and also batctl
warned now about this problem for nearly 5 years. It should therefore no
(serious) problem to remove these warning messages.

More complex commands in batctl are stored in separate files which are
called like the actual command name. This makes it easier to group
functionality and detect which parts belong to a more complex construct.

More complex commands in batctl are stored in separate files which are
called like the actual command name. This makes it easier to group
functionality and detect which parts belong to a more complex construct.

The command itself is called throughputmeter but the file and function is
called tp_meter. Use "throughputmeter" for both to make it easier to
identify the correct source file.

To: b.a.t.m.a.n
The registration of more complex subcommands in batctl required a lot of
extra code to get it integrated in the main routine. This lead to a hard
to read main function which switches between the subcommand which performs
an action.
The command structure allows us to provide an simpler way to insert
functionality. It currently only works for complete separated commands
which operates on already existing batman-adv interface. But it is flexible
enough to later also support the rest of the commands.

From: Sven Eckelmann @ 2018-10-25 16:22 UTC (permalink / raw)
To: b.a.t.m.a.n
Some commands have different prerequists than other commands. Using flags
to specify them would allow batctl to use the same command structure for
the non-mesh_iface based command as for mesh_iface based commands.

From: Sven Eckelmann @ 2018-10-25 16:22 UTC (permalink / raw)
To: b.a.t.m.a.n
The command datastructure was extended to be usable for mesh_iface and
non-mesh_iface subcommands. The referenced subcommands only have to use the
same function signature to work correctly.
The introduction of dummy parameter to the functions allows therefore to
convert all non-settings and non-debug-tables subcommands to the new
infrastructure.

The handwritten option parser is rather fragile and doesn't support all
features of a normal commandline option parser. Instead use getopt to
handle the most critical parts and keep it more flexible.

The single line usage information for a subcommand is the simplest way to
learn how to use a command. It is displayed when either the -h option is
used or when the initial part of the batctl command is incorrect.
Since the commands are no longer registered manually in the main function,
the usage line should also no longer be stored there. Instead add it to the
same file as the command itself.

From: Sven Eckelmann @ 2018-10-25 16:22 UTC (permalink / raw)
To: b.a.t.m.a.n
The command structure first mapped from one name and abbrevation to a
single function of batctl. But there can be commands which share a
significant portion of the code. To support these kind of things better,
add an additional arg pointer to the command structure. The handler then
receive a state struct from the main function instead of the mesh_iface.
The command implementation can then use the state to retrieve both the
mesh_iface and the cmd with the arg pointer.

be preserved when the remaining subcommands are converted to the command
infrastructure.

To: b.a.t.m.a.n
Most of the commands were already converted to the new command
infrastructure. To use the new state and pre-initialization steps, the
debugfs tables also have to be converted.

From: Sven Eckelmann @ 2018-10-25 16:22 UTC (permalink / raw)
To: b.a.t.m.a.n
Most of the commands were already converted to the new command
infrastructure. To use the new state and pre-initialization steps, the
sysfs settings also have to be converted.

The netlink.c file contains to many different functions and mixes helper
functions with actual command implementations. The debug table commands
should be placed in separate files to better group the command specific
code sections together.

The netlink.c file contains to many different functions and mixes helper
functions with actual command implementations. The debug table commands
should be placed in separate files to better group the command specific
code sections together.

To: b.a.t.m.a.n
The netlink.c file contains to many different functions and mixes helper
functions with actual command implementations. The debug table commands
should be placed in separate files to better group the command specific
code sections together.

The other commands are stored in separate files and nc_nodes might also
receive a netlink implementation. The latter would increase the complexity
significantly and thus justify that the command is also added via an extra
file.

The netlink.c file contains to many different functions and mixes helper
functions with actual command implementations. The debug table commands
should be placed in separate files to better group the command specific
code sections together.

functions with actual command implementations. The debug table commands
should be placed in separate files to better group the command specific
code sections together.

The sysfs settings are planned to get also be implemented in netlink. To
avoid cluttering up netlink.c again, it should be stored in a separate
file. This also allows to order the usage lines using the Makefile.

The netlink socket is used by the debug table functionality to retrieve the
tables. The initialization can be centralized and moved to the main
function (controlled by a flag) to share it between the other commands.
Since more commands will use netlink in the future, this flag can reduce
the implementation effort significantly.

From: Sven Eckelmann @ 2018-10-25 16:22 UTC (permalink / raw)
To: b.a.t.m.a.n
It is easier to work on the actual command implementation when its source
code is also saved it the correct source file. Only the shared code should
be in the shared code location.

To: b.a.t.m.a.n
The netlink multicast groups of batman-adv are currently used to inform
userspace about finished throughputmeter runs. It will later also be used
to inform about changes of settings of a specific batadv interface.
The "event" will wait for these messages and print brief summaries about
the received data. This can be used during the development of new features
or to monitor running systems.

To: b.a.t.m.a.n
The variable content of CONFIG_BATCTL_BISECT can be used to decide whether
the bisect_iv command is enabled or not. This would make it possible in the
future to introduce a generic way to enable or disable commands. Combining
this with link-time-optimization and/or function/data-section allows to
relatively freely scale the functionality of batctl and its size.

Systems with limited space are usually not using all the functionality of
batman-adv and of batctl. Still, most of the batctl is still build even
when the corresponding batman-adv functionality would not be available.
This becomes especially important for subcommands which implement most
functionality in userspace when it was previously completely handled by the
kernel.
An external build system for such system can now just select the commands
it really needs. Combining this with link-time-optimizationa and/or
function/data-section garbage collection allows to find the right mix
between size and functionality.
