Detailed Description

Function Documentation

   void nfq_nlmsg_cfg_put_cmd (struct nlmsghdr * nlh, uint16_t pf, uint8_t cmd)
       nfq_nlmsg_cfg_put_cmd Add netlink config command to netlink message

       Parameters
           nlh Pointer to netlink message
           pf Packet family (e.g. AF_INET)
           cmd nfqueue nfnetlink command.

       Possible commands are:

       • NFQNL_CFG_CMD_NONE: Do nothing. It can be useful to know if the queue subsystem is working.

       • NFQNL_CFG_CMD_BIND: Binds the program to a specific queue.

       • NFQNL_CFG_CMD_UNBIND: Unbinds the program to a specifiq queue.

       Obsolete commands:

       • NFQNL_CFG_CMD_PF_BIND:  Binds  to  process packets belonging to the given protocol family (ie. PF_INET,
         PF_INET6, etc).

       • NFQNL_CFG_CMD_PF_UNBIND: Unbinds from processing packets belonging to the given protocol  family.  Both
         commands are ignored by Linux kernel 3.8 and later versions.

       nfq_nlmsg_cfg_put_params Add parameter to netlink message

       Parameters
           nlh Pointer to netlink message

   void nfq_nlmsg_cfg_put_qmaxlen (struct nlmsghdr * nlh, uint32_t queue_maxlen)
       nfq_nlmsg_cfg_put_qmaxlen Add queue maximum length to netlink message

       Parameters
           nlh Pointer to netlink message
           queue_maxlen Maximum queue length
