Hi,
I'm a student in computer science and for my master thesis i have to
handle packets in a userspace queue. Libipq works fine for me, except
one information which is missing: the owner of a (transmitted) packet.
With the following two additional lines, the problem seems to be solved:
in file
include/linux/netfilter_ipv4/ip_queue.h
in
typedef struct ipq_packet_msg_t
line 33 add:
unsigned int uid; /* uid of packet owner*/
in file
net/ipv4/netfilter/ip_queue.c
line 249 add:
pmsg->uid = entry->skb->sk->sk_socket->file->f_uid;
Initial tests have been successful and are showing the correct uid in
ipq_packet_msg_t in userspace. Please tell me, what you think about
this modification.
Since I found some other people who are looking for the same
information, i wonder if there is a possibility to include the uid
field officially in the source of netfilter?!
Regards,
Jack
