cfa55c6d47 batman-adv: Drop publication years from copyright info
The batman-adv source code was using the year of publication (to net-next)
as "last" year for the copyright statement. The whole source code mentioned
in the MAINTAINERS "BATMAN ADVANCED" section was handled as a single entity
regarding the publishing year.

This avoided having outdated (in sense of year information - not copyright
holder) publishing information inside several files. But since the simple
"update copyright year" commit (without other changes) in the file was not
well received in the upstream kernel, the option to not have a copyright
year (for initial and last publication) in the files are chosen instead.
More detailed information about the years can still be retrieved from the
SCM system.

e2d0d35b5b batman-adv: Add gateway mesh genl configuration
The mesh/soft-interface can optimize the handling of DHCP packets. Instead
of flooding them through the whole mesh, it can be forwarded as unicast to
a specific gateway server. The originator which injects the packets in the
mesh has to select (based on sel_class thresholds) a responsible gateway
server. This is done by switching this originator to the gw_mode client.
The servers announce their forwarding bandwidth (download/upload) when the
gw_mode server was selected.

The BATADV_CMD_SET_MESH/BATADV_CMD_GET_MESH commands allow to set/get the
configuration of this feature using the attributes:

* u8 BATADV_ATTR_GW_MODE (0 == off, 1 == client, 2 == server)
* u32 BATADV_ATTR_GW_BANDWIDTH_DOWN (in 100 kbit/s steps)
* u32 BATADV_ATTR_GW_BANDWIDTH_UP (in 100 kbit/s steps)
* u32 BATADV_ATTR_GW_SEL_CLASS

fec149f5d3 batman-adv: Convert packet.h to uapi header

or to decode sniffed packets. It should therefore be available to them as
userspace header.

Also other components in the kernel (like the flow dissector) require

packets.

1a9070ec91 batman-adv: Initialize gw sel_class via batadv_algo
The gateway selection class variable is shared between different algorithm
versions. But the interpretation of the content is algorithm specific. The
initialization is therefore also algorithm specific.

But this was implemented incorrectly and the initialization for BATMAN_V
always overwrote the value previously written for BATMAN_IV. This could
only be avoided when BATMAN_V was disabled during compile time.

Using a special batadv_algo hook for this initialization avoids this
problem.

0b8336f5fc batman-adv: Fix gw_bandwidth calculation on 32 bit systems
The TVLV for the gw_bandwidth stores everything as u32. But the
gw_bandwidth reads the signed long which limits the maximum value to
(2 ** 31 - 1) on systems with 4 byte long. Also the input value is always
converted from either Mibit/s or Kibit/s to 100Kibit/s. This reduces the
values even further when the user sets it via the default unit Kibit/s. It
may even cause an integer overflow and end up with a value the user never
intended.

Instead read the values as u64, check for possible overflows, do the unit
adjustments and then reduce the size to u32.

1e2c2a4fe4 batman-adv: Add required includes to all files
The header files could not be build indepdent from each other. This is
happened because headers didn't include the files for things they've used.
This was problematic because the success of a build depended on the
knowledge about the right order of local includes.

Also source files were not including everything they've used explicitly.
Instead they required that transitive includes are always stable. This is
problematic because some transitive includes are not obvious, depend on
config settings and may not be stable in the future.

The order for include blocks are:

 * primary headers (main.h and the *.h file of a *.c file)
 * global linux headers
 * required local headers
 * extra forward declarations for pointers in function/struct declarations

The only exceptions are linux/bitops.h and linux/if_ether.h in packet.h.
This header file is shared with userspace applications like batctl and must
therefore build together with userspace applications. The header
linux/bitops.h is not part of the uapi headers and linux/if_ether.h
conflicts with the musl implementation of netinet/if_ether.h. The
maintainers rejected the use of __KERNEL__ preprocessor checks and thus
these two headers are only in main.h. All files using packet.h first have
to include main.h to work correctly.

b7a8d756fb batman-adv: replace strnicmp with strncasecmp
The kernel used to contain two functions for length-delimited,
case-insensitive string comparison, strnicmp with correct semantics and
a slightly buggy strncasecmp.  The latter is the POSIX name, so strnicmp
was renamed to strncasecmp, and strnicmp made into a wrapper for the new
strncasecmp to avoid breaking existing users.

To allow the compat wrapper strnicmp to be removed at some point in the
future, and to avoid the extra indirection cost, do
s/strnicmp/strncasecmp/g.

37a4065ec7 batman-adv: Only use int up and down gw representation

conversation routines.
