There was a regression introduced with the previous commit:
"ipv6 nd home-agent-lifetime 1800000" appeared by default in every
interface section of running-config, although this command is
invalid in this context. Troubleshooting and bugfixing of the issue
tracked out several bugs in router advertisement procedures, some of
which are fixed in this commit.
* zebra/interface.c
* if_zebra_new_hook(): update to treat -1 as "uninitialized"
* nd_dump_vty(): idem
* zebra/rtadv.c
* rtadv_send_packet(): update processing of "router lifetime" field,
"home agent" option and "home agent lifetime" field to conform to
RFC6275 better
* ipv6_nd_ra_interval_msec(): update MaxRtrAdvInterval range check,
make sure it never exceeds (initialized) AdvDefaultLifetime
* ipv6_nd_ra_interval(): idem
* ipv6_nd_ra_lifetime(): update AdvDefaultLifetime range check, make
sure it never falls below MaxRtrAdvInterval
* ipv6_nd_homeagent_lifetime(): update HomeAgentLifetime range check
* no_ipv6_nd_ra_lifetime(): update to treat -1 as "uninitialized"
* no_ipv6_nd_homeagent_lifetime(): idem
* rtadv_config_write(): idem

The following options could be configured for an interface, but were
never visible in the config text:
ipv6 nd adv-interval-option
ipv6 nd home-agent-preference
ipv6 nd home-agent-lifetime
ipv6 nd home-agent-config-flag

This implements a new "ipv6 nd mtu <1-65535>" interface-level command.
* doc/ipv6.texi: add description
* zebra/rtadv.c
* rtadv_send_packet(): send option type 5, when configured
* ipv6_nd_mtu(): new VTY helper

|
|
* (general) Move functions in headers into files, to be compiled into
shared object files. Remove inline qualifier from functions. Let the
compiler do the work.

When the same ip address is used on several interfaces,
and one of them gets deleted (or equivalent: set to down and
then address removed), rib_delete_ipv[46] will also remove
the connected route from other interfaces.
rib_delete_ipv[46] is called twice when an interface is
deleted:
- for the "ifdown" event
- for the address removal
(note: this may be specific to the netlink interface of linux)
The second call does not find the connected route to that same
ifindex anymore, but deletes similar connected routes to any
other ifindex instead.
Reason: the ifindex check is on the same level as the check
for ZEBRA_ROUTE_CONNECT/NEXTHOP_TYPE_IFINDEX. If everything
matches except for the ifindex, the "else" part (intended for
different route types) is executed, thus removing the route
from the wrong interface.
fix: move ifindex check inside the "then" part of the check
for ZEBRA_ROUTE_CONNECT/NEXTHOP_TYPE_IFINDEX. Now connected
routes to other ifindexes will not spill over to the "else"
part for different route types anymore.

ZEBRA_HELLO message is used by routing daemons to inform zebra
what type of routes daemon will be announcing to zebra. Also
zebra uses route_type_oaths array to track which daemon announces
which protocol. Zebra mops up routes if daemon didn't for some
reason.

(This patch was modified to leave calls to stream_getl() in place, they
are necessary for the stream's internal pointer to advance to the
correct position. -- Denis)

this replaces most occurences of routing protocol lists by preprocessor
defines from route_types.h. the latter is autogenerated from
route_types.txt by a perl script (previously awk). adding a routing
protocol now is mostly a matter of changing route_types.txt and log.c.
Conflicts:
lib/route_types.awk

redistribute is currently limited to "known" protocols. there is no
reason for this limitation, so, remove it.
|
|
adding protocols and forgetting to update zebra_rib.c currently causes
a beyond end of array access for the default distance value. fix by
making 150 the default distance for unknown routing protocols.
150 is higher than all other IGPs but lower than iBGP (200)

* kernel_socket.c: (ifm_read) The reorganization from commit
6fe70d1b35c189cb1e488b2c26551ba7baac6148 removed setting the
interface link-layer socket address structure on routing socket
platforms. This restores saving the link-layer information because
it might be used elsewhere: rtm_write() when no gateway is given,
if_dump_vty() and rtadv_send_packet().

The router-id table looks like is supposed to be sorted in current
quagga code, but the nodes are not added with the sorting
function.
The sorting function is host byte order dependent.
The values need to converted before comparison.
Fixing this causes Zebra to choose the largest IP address
as router-id, rather than the last address. This probably will
surprise some users. The other option would be to just remove the
comparison function and keep the existing LIFO behavior.
Lastly, simple subtraction works well for comparing.

* router_id_cmp(): employ ntohl(), then compare integers

The RTF_CLONING flag has been removed in FreeBSD 8.0 with arp-v2 (see
http://svn.freebsd.org/viewvc/base/stable/8/UPDATING?view=markup),
since it no longer has any meaning. This patch checks if RTF_CLONING
exists before using it.

* kernel_socket.c: (rtm_flag_dump) Use a const message pointer to be

* rtadv.c: round up when calculating the link-layer address option length;
add padding to the option if needed to end on an octet boundary

* testrib.conf: Example config file for testzebra

* test_main.c: If required arguments are missing, say that.
|
|
* */*main.c: (main) Current versions of Gcc warn if the return value for
daemon() is not checked. So add a simple test and exit on failure.
|
|
* kernel_null.c: we're pretending to add an address, so
set IFC_REAL. If this isn't done, calling into the 'got address
from kernel' half of zebra will implicitly-withdraw the ifc, which
could cause a crash in test_zebra.c.

Move zserv socket creation code into zebra_zserv_socket_init() and

A static route like below: ip route 172.16.1.0/30 192.168.101.162 11
does not move properly to a new interface when the
interface used goes down. Zebra reports that it have
moved but kernel isn't informed so the route is lost.
* zebra_rib.c: (nexthop_active_update) if ifindex has changed, then the
route should be considered to have changed.

Quagga support linux policy routing (ip route ... table $X) with zebra.conf
table $X option. It works fine on ipv4. On ipv6 the parameter is ignored
(table 0 is used).

nowadays is to just replace it.
