Andrew Lunn (2):
Fix the naming of the debug option in Kconfig.
Add Kconfig dependancies on PROC_FS and PACKET. signed-off-by: Andrew
Lunn <andrew@lunn.ch>
marek (4):
[batman-adv] replace internal logging mechanism with standard kernel
logging
[batctl adapt batctl to the new logging mechanisms
Updating orig_str for debug
[batman-adv] correctly name the configuration option for debugging
simon (4):
Andrews refactored routing.c file patch: "I broke a lot of the big
functions up into many smaller ones. This helps with readability
and there is now a lot less code squashed against the right
margin."
stop permanent warnings if a device is added but deactivated.
split originator handling parts off routing.c
if discarding a packet, we need to read it under any condition.

+All error messages, warnings and information messages are sent to the
+kernel log. Depending on your operating system distribution this can be
+read in one of a number of ways. Try using the commands: dmesg,
+logread, or looking in the files /var/log/kern.log or
+/var/log/syslog. All batman-adv messages are prefixed with
+"batman-adv:" So to see just these messages try
+
+dmesg | grep batman-adv
+
+When investigating problems with your mesh network it is sometimes

+compiling the batman-adv module. When building batman-adv as part of
+kernel, use "make menuconfig" and enable the option

+The additional debug output is by default disabled. It can be enabled
+either at kernel modules load time or during run time. To enable debug
+output at module load time, add the module parameter debug=<value>.
+<value> can take one of four values.
+

+3 - Enable all messages

+
+modprobe batman-adv debug=2
+
+will load the module and enable debug messages for when routes or HNAs

+The debug output can also be changed at runtime using the file

In commit 1488 the orig_str has been removed from
purge_orig_neighbours(). Apparently, this breaks compilation when
enabling debug-flags, as bat_dbg() is expecting this variable as a
parameter. Actually, this variable has never been initialised also
before commit 1488 (which was probably the reason for mistakenly
removing it).
This tiny patch adds the orig_str again, but initialises it now as
well.

First off, much better on sending the patches, that worked fine.

But it seems that only this one, and one other (10/10) are able to be
applied to the kernel tree, as they properly have the files in the
correct location.
What were the other patches against? A local repo somewhere that did
not have the batman-adv code in drivers/staging/batman-adv?
