[quagga-dev 10532] bgp and Multiprotocol Extension Capability

'Chris Hall' — 2013-05-13T20:10:34

If a neighbour sends no Multiprotocol Extension Capability (MP-Ext) at
all, Quagga will happily assume that the neighbour supports all the
afi/safi it is configured for.

This strikes me as broken.  RFC4760 says that one or more MP-Ext
capabilities implies that the BGP speaker "uses Multiprotocol
Extensions".  The RFC does not specify what the absence of any MP-Ext
means, but I think it reasonable to assume a BGP speaker that does not
"use Multiprotocol Extensions" is implicitly an unadorned IPv4 Unicast
BGP speaker.

Does anyone think it is unreasonable to treat current behaviour as a
bug ?

I guess most BGP implementations these days send MP-Ext for every
afi/safi supported, even if that is only IPv4 Unicast ?  I note that
BIRD has an option:

  advertise ipv4 switch

  Advertise IPv4 multiprotocol capability. This is not a correct
  behavior according to the strict interpretation of RFC 4760,
  but it is widespread and required by some BGP implementations
  (Cisco and Quagga). This option is relevant to I

[quagga-dev 10530] Some GSOC proposals

hervé frantz — 2013-05-10T11:03:26

Hi to everybody,
I have a set of proposition and questions that can be often used for GSOC
and everyone is welcome to give is point of view

*OpenFlow INTEGRATION*

It is planned to join quagga in the SDN moving ? if Openflow should be
integrated should be in the OS or Quagga itself?

*Quagga and other routing protocols implementation*

I have a question about quagga interoperability with other opensource
software implementation (BIRD, XORP, OpenBGPd/OpenOSPFd) and even vendor
implementation address to quagga developer and adminis . Does quagga work
well in a heterogeneous environment? Is it a need to make quagga more
interoperable with other implementation?

*IDRP implementation*

What do you think about some IDRP implementation within quagga *?

*
*NETCONF integration for Quagga

*What do you think about some IDRP integration within quagga *?*



the discussion is open so don't hesitated

have a nice day, Frantz Kengne

[quagga-dev 10527] RFC-6506(Supporting Authentication Trailer for OSPFv3) implementation in quagga-0.99.21 version

Lokesh Pareta — 2013-05-09T05:41:58

Hi All,

Tata Consultancy Services (TCS) wants to contribute to Quagga development 
by providing the implementation code for RFC-6506, developed and tested on 
quagga-0.99.21 version. 

Abstract of the RFC-6506:
Currently, OSPF for IPv6 (OSPFv3) uses IPsec as the only mechanism for 
authenticating protocol packets.
This behavior is different from authentication mechanisms present in other 
routing protocols (OSPFv2, Intermediate System to Intermediate System 
(IS-IS), RIP, and Routing Information Protocol Next Generation (RIPng)). 
In some environments, it has been found that IPsec is difficult to 
configure and maintain and thus cannot be used. 
RFC-6506 defines an alternative mechanism to authenticate OSPFv3 protocol 
packets so that OSPFv3 does not only depend upon IPsec for authentication.

Steps to test/run the developed patch file on quagga-0.99.21 :
As per RFC, implementation is done by TCS in order to provide 
authentication support on both interface and area.
Commands to be used are as follows:

[quagga-dev 10496] Additional GSoC Proposal

Nathan Wilder — 2013-05-01T19:51:47

Quagga Community,

Unless you all have any objections, I would like to submit a second proposal for GSoC.  The OSPF replay and testing tool is still hands down my preferred project.  But as it seem to be a popular choice among potential GSoC students, I'd like to submit an additional proposal for the Zebra IPC clean-up in case I'm not selected to work on the OSPF tool.  It looks like an interesting endeavor that would get me familiar with all the Quagga components, although I do have some concerns about thorough testing, particularly with those protocols with which I have no experience (Babel, ISIS, and only have a little knowledge of RIP).  I'd assume that any testing I would do would be supplemented by and any code reviewed by the community before it's committed? 

So, the way I understand this clean-up project is that the Zebra IPC exchanges route information among the daemons and the local machine-specific route stack.  However, this IPC is interfaced to each daemon in different ways specific to th

[quagga-dev 10489] Adding "encapsulation dot1q" option to interfaces

Adrian Ban — 2013-05-01T11:39:17

Hi,

I want to try to add the possibility to create VLANs subinterfaces 
directly from Quagga.
The reason is that I hate to do it all the time from the OS with iproute 
or OS specific init.d scripts. More elegant is to do it from one 
combined CLI.

 From the point of view of the programming logic seems to not be to 
difficult.

But I'm not very familiarly with the quagga libs and I need some help 
from you or some points of start.

For the part of netlink/rtnetlink I can handle it (already found what I 
need and also the parameters I need to set in the netlink message, 
inspired from iproute, to be send to the kernel).

But before I send the message to the kernel I need to make some sanity 
checks before the "encapsulation dot1q <1-4094>" command to be send.

So this is what I want to do:

1. check the interface name to be in a format like this: eth0.243
2. extract the real interface from the interface name: eth0
3. check if the dot1q parameter is in the range 1-4094 (already done it)
4. check if the specif

[quagga-dev 10488] ripd/rip_interface.c memleak from inappropriatestrdup() calls

Charlet, Ricky — 2013-05-01T00:09:09

Howdy,
        I'm new around these parts and just jumping into quagga code.

        During review, I believe I've spotted a few memory leaks in ripd/rip_interface.c.  In several places, there are calls to stdlib.h's strdup() function. Memory returned from strdup() never seems to be free'd.  For example:

/* Add interface to rip_enable_if. */
static int
rip_enable_if_add (struct rip *rip, const char *ifname)
{
  int ret;

  ret = rip_enable_if_lookup (rip, ifname);
  if (ret >= 0)
    return -1;

  vector_set (rip->rip_enable_interface, strdup (ifname));

  rip_enable_apply_all (rip); /* TODOVJ */

  return 1;
}


        I'm just tossing this out as an FYI cause I've been wrong before (especially when I'm in a new code base). So will someone else put some eyeballs on that and see if you think those are true memleaks? And if they are not, I would love to be educated.

Thanks.

Hi,

It is very great full if interested mentor for GSOC willing to help with
this idea. This is a fairly new concept and only very few implementations
are available.
so it will be grate if it is available through the open source world.

I'll be posting a proposal at gsoc melange.
but regardless of gsoc i' ll need some help for this implementation.
so any developer is welcome to help me on this implementation.

Thank you.

Dear Quagga developers,

I'm studying in Brno University of Technology, Faculty of Information

I've succesfully passed CCNA1 (Networking fundamentals) and on 2nd May, I'm

not SW for routers, but in those courses I've understood the principles of
routing protocols and some commands that are similar to the ones used in
Quagga, as I've read in documentation. I've also quite good knowledge of
UNIX, kernel, signals etc. In May, I'm taking Computer Communications and
Networks exam, which I hope will give

This patch (attached) updates my previously-posted patch of April 10:

0. patch against Apr 24, 2013 git version

1. thread.c: Remove overflow handling change - take up later in separate
   patch after further study.

2. skiplist.c: 

    static int
    randomLevel(void)

3. thread.h: Add forward declaration "struct skiplist;" and
   add "struct skiplist *skiplist_timer" to the thread master
   structure.

   thread.c: Change void* skiplist pointer to struct skiplist*

4. Put skiplist test functions in separate file under tests/test-skiplist.c

It still has the thread code to use skiplists under control of
THREAD_TIMER_USE_SKIPLIST. Christian, I can spin another version
of the patch without these ifdefs if you think it is warranted.
