Hi,
There are ioctl's for attaching bpf like filters to socket. I found it
in kernel documentation.
setsockopt(sockfd, SOL_SOCKET, SO_ATTACH_FILTER, &Filter, sizeof(Filter));
I doubt is can we attach filters in case of netlink socket.
I am logging all packets using ULOG target and using ulogd.
Is it possible to use same ioctl for netlink socket we create in ulogd?

You can use socket filters on netlink sockets since 2.6.26 ^ permalink raw reply [flat|nested] 3+ messages in thread

My kernel is 2.6.27.45 :). I am taking bpf string like "host <ip>" from command prompt and doing "pcap_compile_nopcap". Create my filter and do setsockopt but I am not able to get result i wanted. May be i am doing something wrong in creating filters. I am using link type as DLT_RAW.
