|IPQ_SET_VERDICT(3)||Linux Programmer's Manual||IPQ_SET_VERDICT(3)|
int ipq_set_verdict(const struct ipq_handle *h, ipq_id_t id, unsigned int verdict, size_t data_len, unsigned char *buf);
The h parameter is a context handle which must previously have been returned successfully from a call to ipq_create_handle.
The id parameter is the packet identifier obtained via ipq_get_packet.
The verdict parameter must be one of:
- Accept the packet and continue traversal within the kernel.
- Drop the packet.
- Requeue the packet.
NF_STOLEN and NF_REPEAT are kernel-internal constants and should not be used from userspace as their exact side effects have not been investigated.
The data_len parameter is the length of the data pointed to by buf, the optional replacement payload data.
If simply setting a verdict without modifying the payload data, use zero for data_len and NULL for buf.
The application is responsible for recalculating any packet checksums when modifying packets.
On success, a non-zero positive value is returned.
