Hello,
I am doing development work on the 2.4.0 kernel, and can not seem to get
multicasting to work.
I have included two test files which I attempted to run, one as a
sender, and another as the receiver. The
code worked as expected on a stock redhat 6.2 - linux 2.2.14-5.0 kernel.
I have found from tcpdump that the
IGMP packets that are supposed to be sent when (un)subscribing to a
group are not being sent. I am using an
ARM build for the application, but I don't believe that the problem
resides in ARM specific code, since I also
tested this feature on a 2.4.0test11 - i386 as well.
Also included is the ethernet driver modified by us for the 2.4 kernel.
I have not seen anything that would
affect this problem, but it is included just in case.
Any help would be much appreciated.
BTW: I may be doing something really stupid, please be gentle ;-)

I am doing development work on the 2.4.0 kernel, and can not seem to get
multicasting to work.
I have included two test files which I attempted to run, one as a
sender, and another as the receiver. The
code worked as expected on a stock redhat 6.2 - linux 2.2.14-5.0 kernel.
I have found from tcpdump that the
IGMP packets that are supposed to be sent when (un)subscribing to a
group are not being sent. I am using an
ARM build for the application, but I don't believe that the problem
resides in ARM specific code, since I also
tested this feature on a 2.4.0test11 - i386 as well.
Also included is the ethernet driver modified by us for the 2.4 kernel.
I have not seen anything that would
affect this problem, but it is included just in case.
Any help would be much appreciated.
BTW: I may be doing something really stupid, please be gentle ;-)

Changelog:
Mike Cruse : mcruse@cti-ltd.com
: Changes for Linux 2.0 compatibility.
: Added dev_id parameter in net_interrupt(),
: request_irq() and free_irq(). Just NULL for now.
Mike Cruse : Added MOD_INC_USE_COUNT and MOD_DEC_USE_COUNT macros
: in net_open() and net_close() so kerneld would know
: that the module is in use and wouldn't eject the
: driver prematurely.
Mike Cruse : Rewrote init_module() and cleanup_module using 8390.c
: as an example. Disabled autoprobing in init_module(),
: not a good thing to do to other devices while Linux
: is running from all accounts.
Russ Nelson : Jul 13 1998. Added RxOnly DMA support.
Melody Lee : Aug 10 1999. Changes for Linux 2.2.5 compatibility.
: email: ethernet@crystal.cirrus.com
Alan Cox : Removed 1.2 support, added 2.1 extra counters.
Andrew Morton : andrewm@uow.edu.au
: Kernel 2.3.48
: Handle kmalloc() failures
: Other resource allocation fixes
: Add SMP locks
: Integrate Russ Nelson's ALLOW_DMA functionality back in.
: If ALLOW_DMA is true, make DMA runtime selectable
: Folded in changes from Cirrus (Melody Lee
: <klee@crystal.cirrus.com>)
: Don't call netif_wake_queue() in net_send_packet()
: Fixed an out-of-mem bug in dma_rx()
: Updated Documentation/cs89x0.txt

I frequently experiment with "zebra" (http://www.zebra.org) routing engine
and multicasting works for me (2.4.0-test11), according to tcpdump and
observed behavior.
If you have multiple interfaces with the same IP address (point-to-point
interfaces: same local address) then it is possible that the packets go
out via the wrong interface. This has bitten me once.
