[batman-adv] maint: batman-adv: set up network coding packet handlers during module init (586cf84)

Repository : ssh://git@open-mesh.org/batman-adv On branch : maint >--------------------------------------------------------------- commit 586cf84b0ce6f9e8faa95e5f435de4be49a7eb88 Author: Matthias Schiffer <mschiffer(a)universe-factory.net> Date: Fri Sep 27 18:03:39 2013 +0200 batman-adv: set up network coding packet handlers during module init batman-adv saves its table of packet handlers as a global state, so handlers must be set up only once (and setting them up a second time will fail). The recently-added network coding support tries to set up its handler each time a new softif is registered, which obviously fails when more that one softif is used (and in consequence, the softif creation fails). Fix this by splitting up batadv_nc_init into batadv_nc_init (which is called only once) and batadv_nc_mesh_init (which is called for each softif); in addition batadv_nc_free is renamed to batadv_nc_mesh_free to keep naming consistent.

[alfred] master: alfred: Don't fail rebuild when header is removed (133331a)

Repository : ssh://git@open-mesh.org/alfred On branch : master >--------------------------------------------------------------- commit 133331a3dc2e3011de6d4db70feb11544c47cb1b Author: Sven Eckelmann <sven(a)narfation.org> Date: Sat Sep 21 16:31:14 2013 +0200 alfred: Don't fail rebuild when header is removed The *.d depends files for make just list the files used when building an object file. Removing a file listed in such a dependency file causes make to search for a way to recreate it. This usually cannot work because these files aren't autogenerated. The gcc option -MP can be used to generate empty rule for these files. Removing a file in a dependency list will then execute this empty rule and continue with the execution of the creation of the object file. This compilation process will then automatically correct the dependency file.

This data can be anything which +appears to be useful - originally designed to replace the batman-adv +visualization (vis), you may distribute hostnames, phone books, administration +information, DNS information, the local weather forecast ... +.PP +alfred runs as daemon in the background of the system. A user may insert +information by using the alfred binary on the command line, or use special +programs to communicate with alfred (done via unix sockets). alfred then takes +care of distributing the local information to other alfred servers on other +nodes. This is done via IPv6 link-local multicast, and does not require any +configuration. A user can request data from alfred, and will receive the +information available from all alfred servers in the network. +.PP +.PP +.SH OPTIONS +.TP +\fB\-v\fP, \fB\-\-version\fP +Print the version +.TP +\fB\-h\fP, \fB\-\-help\fP +Display a brief help message. +. +.SH CLIENT OPTIONS +.TP +\fB\-s\fP, \fB\-\-set\-data\fP \fIdata\-type\fP +Sets new data to distribute from stdin for the supplied data type (0\-255). + +Note that 0 - 63 are reserved (please send an e-mail to the authors if you want +to register a datatype), and can not be used on the commandline.

Masters will +exchange their data (which they have received from slaves or got on their own) +with other masters.

[batctl] next: batctl tcpdump: Fix reported length of TCP payload (e374a3f)

Previously TCP header length size was considered fixed, while this is actually not the case given the variable length (or no presence at all) of the options field.
