Hello all,
I'm working on an implementation of the IGMPv3 protocol in the Net/3
stack, and several questions popped up. The first one is about the
socket structure.
The IGMPv3 protocol allows a process to set (ip)source filters, which is
a list of ip addresses of sources which indicates the pro
Hi,
As part of an IGMPv3 implementation on FreeBSD I
had to add a list to a datastructure (in_multi). This list can be set by users
(using ioctl) and be replaced later. While
replacing this list, there is the possibility (ad1) of a concurrent reader (the
process when an incoming packet has
Could anybody advise me on this:
For an implementation of IGMPv3, I
had to extend the socket api
following the draft(s). I had to add
two ioctl commands:
SIO_GET_MULTICAST_FILTER and SIO_SET_MULTICAST_FILTER.
The argument is a
structure that has a variable size.
FreeBSD uses some macros, and the
Maybe obvious to some of you, but I had to define two new structures (as
described in an ietf draft) in . This in order to be able to
support igmpv3 / multicast source filters. Anyway, these structures require
'struct sockaddr_storage' which is defined in .
When I compiled the code, it stopped si
