''' RTNetlink: network setup ======================== RTNL is a netlink protocol, used to get and set information about different network objects -- addresses, routes, interfaces etc. RTNL protocol-specific data in messages depends on the object type. E.g., complete packet with the interface address information:: nlmsg header: + uint32 length + uint16 type + uint16 flags + uint32 sequence number + uint32 pid ifaddrmsg structure: + unsigned char ifa_family + unsigned char ifa_prefixlen + unsigned char ifa_flags + unsigned char ifa_scope + uint32 ifa_index [ optional NLA tree ] NLA for this kind of packets can be of type IFA_ADDRESS, IFA_LOCAL etc. -- please refer to the corresponding source. Other objects types require different structures, sometimes really complex. All these structures are described in sources. --------------------------- Module contents: ''' from pyroute2.common import map_namespace # RTnetlink multicast groups RTNLGRP_NONE = 0x0 RTNLGRP_LINK = 0x1 RTNLGRP_NOTIFY = 0x2 RTNLGRP_NEIGH = 0x4 RTNLGRP_TC = 0x8 RTNLGRP_IPV4_IFADDR = 0x10 RTNLGRP_IPV4_MROUTE = 0x20 RTNLGRP_IPV4_ROUTE = 0x40 RTNLGRP_IPV4_RULE = 0x80 RTNLGRP_IPV6_IFADDR = 0x100 RTNLGRP_IPV6_MROUTE = 0x200 RTNLGRP_IPV6_ROUTE = 0x400 RTNLGRP_IPV6_IFINFO = 0x800 RTNLGRP_DECnet_IFADDR = 0x1000 RTNLGRP_NOP2 = 0x2000 RTNLGRP_DECnet_ROUTE = 0x4000 RTNLGRP_DECnet_RULE = 0x8000 RTNLGRP_NOP4 = 0x10000 RTNLGRP_IPV6_PREFIX = 0x20000 RTNLGRP_IPV6_RULE = 0x40000 RTNLGRP_MPLS_ROUTE = 0x4000000 # Types of messages # RTM_BASE = 16 RTM_NEWLINK = 16 RTM_DELLINK = 17 RTM_GETLINK = 18 RTM_SETLINK = 19 RTM_NEWADDR = 20 RTM_DELADDR = 21 RTM_GETADDR = 22 RTM_NEWROUTE = 24 RTM_DELROUTE = 25 RTM_GETROUTE = 26 RTM_NEWNEIGH = 28 RTM_DELNEIGH = 29 RTM_GETNEIGH = 30 RTM_NEWRULE = 32 RTM_DELRULE = 33 RTM_GETRULE = 34 RTM_NEWQDISC = 36 RTM_DELQDISC = 37 RTM_GETQDISC = 38 RTM_NEWTCLASS = 40 RTM_DELTCLASS = 41 RTM_GETTCLASS = 42 RTM_NEWTFILTER = 44 RTM_DELTFILTER = 45 RTM_GETTFILTER = 46 RTM_NEWACTION = 48 RTM_DELACTION = 49 RTM_GETACTION = 50 RTM_NEWPREFIX = 52 RTM_GETMULTICAST = 58 RTM_GETANYCAST = 62 RTM_NEWNEIGHTBL = 64 RTM_GETNEIGHTBL = 66 RTM_SETNEIGHTBL = 67 # custom message types RTM_GETBRIDGE = 88 RTM_SETBRIDGE = 89 RTM_GETBOND = 90 RTM_SETBOND = 91 (RTM_NAMES, RTM_VALUES) = map_namespace('RTM', globals()) TC_H_INGRESS = 0xfffffff1 TC_H_CLSACT = TC_H_INGRESS TC_H_ROOT = 0xffffffff RTNL_GROUPS = RTNLGRP_IPV4_IFADDR |\ RTNLGRP_IPV6_IFADDR |\ RTNLGRP_IPV4_ROUTE |\ RTNLGRP_IPV6_ROUTE |\ RTNLGRP_IPV4_RULE |\ RTNLGRP_IPV6_RULE |\ RTNLGRP_NEIGH |\ RTNLGRP_LINK |\ RTNLGRP_TC |\ RTNLGRP_MPLS_ROUTE encap_type = {'unspec': 0, 'mpls': 1, 0: 'unspec', 1: 'mpls'} rtypes = {'RTN_UNSPEC': 0, 'RTN_UNICAST': 1, # Gateway or direct route 'RTN_LOCAL': 2, # Accept locally 'RTN_BROADCAST': 3, # Accept locally as broadcast # send as broadcast 'RTN_ANYCAST': 4, # Accept locally as broadcast, # but send as unicast 'RTN_MULTICAST': 5, # Multicast route 'RTN_BLACKHOLE': 6, # Drop 'RTN_UNREACHABLE': 7, # Destination is unreachable 'RTN_PROHIBIT': 8, # Administratively prohibited 'RTN_THROW': 9, # Not in this table 'RTN_NAT': 10, # Translate this address 'RTN_XRESOLVE': 11} # Use external resolver # normalized rt_type = dict([(x[0][4:].lower(), x[1]) for x in rtypes.items()] + [(x[1], x[0][4:].lower()) for x in rtypes.items()]) rtprotos = {'RTPROT_UNSPEC': 0, 'RTPROT_REDIRECT': 1, # Route installed by ICMP redirects; # not used by current IPv4 'RTPROT_KERNEL': 2, # Route installed by kernel 'RTPROT_BOOT': 3, # Route installed during boot 'RTPROT_STATIC': 4, # Route installed by administrator # Values of protocol >= RTPROT_STATIC are not # interpreted by kernel; # keep in sync with iproute2 !
