batman-adv: Convert batadv_dat_addr_t to proper type

2018-07-08T10:56:38+00:00

The #define for batadv_dat_addr_t is doing nothing else than giving u16 a
new typename. But C already has the special keyword "typedef" which is also
better supported by kernel-doc.

batman-adv: Join batadv_purge_orig_ref and _batadv_purge_orig

2018-07-07T20:02:17+00:00

The single line function batadv_purge_orig_ref has no function beside
providing the name used by other source files. This can also be done
simpler by just renaming _batadv_purge_orig to batadv_purge_orig_ref.

batman-adv: Unify include guards style

2018-07-07T20:02:17+00:00

All other include guards in batman-adv use the style:

* _NET_BATMAN_ADV_$(FILENAME)_
* uppercase only
* "." & "-" replaced with "_"

Use this also in the B.A.T.M.A.N. IV/V OGM implementation headers.

batman-adv: Remove "default n" in Kconfig

2018-06-23T08:30:06+00:00

The "default n" is the default value for any bool or tristate Kconfig
setting. It is therefore not necessary to add it to a config entry.

batman-adv: enable DAT by default at compile time

2018-06-23T08:30:06+00:00

DAT (Distributed ARP Table) has been enabled by default
in the out-of-tree batman-adv kernel module for several
years already.
It can now be enabled in the kernel too.

batman-adv: Drop "experimental" from BATMAN_V Kconfig

2018-06-23T08:30:06+00:00

The Kconfig option BATMAN_ADV_BATMAN_V is now enabled by default when the
BATMAN_ADV is enabled. A feature which is enabled by default for a module
should not be considered experimental.

batman-adv: Fix multicast TT issues with bogus ROAM flags

2018-06-23T08:29:33+00:00

When a (broken) node wrongly sends multicast TT entries with a ROAM
flag then this causes any receiving node to drop all entries for the
same multicast MAC address announced by other nodes, leading to
packet loss.

Fix this DoS vector by only storing TT sync flags. For multicast TT
non-sync'ing flag bits like ROAM are unused so far anyway.
