Based on RFC-5340, there could be multiple Router LSAs
associated with Same Advertising Router. During SPF calculation
ensure first Root Vertex accommodates all Link state IDs for its
originated Router LSAs push them into priority queue.
Similarly follow for other Vertexes, considering Router LSAs
with multiple Link State IDs.
Ticket: CM-18069
Testing Done:
Topology: R1 === R2 -- R3
Validated with more than 100 Subinterfaces
between R1 === R2 with broadcast links,
Validated show ipv6 ospf6 spf tree containing all graph nodes.
Validated ip -6 route at R3 and all intra prefix LSAs route
installed with ospf6 as protocol.
2) Run R1 === R2 with Point-to-Point links.
3) Perform few other abr and ospf6 test cases of LSA ageout,
route install and delete cases.

When the kernel installs/updates a lsp the return code for
success is a 0. The code was interpreting the 0 as a failure
case for the Install/Update code paths. This caused upon
a true deletion zebra loosing knowledge of the lsp
but the kernel still had it installed.

Signed-off-by: Donald Sharp <sharpd@cumulusnetworks.com>
The SET_FLAG(nexthop->flags, NEXTHOP_FLAG_FIB)
is already taken care of in zebra_rib.c. There
is no need for this to be handled by rt_socket.c.
rt_netlink.c does not do a SET_FLAG(nexthop->flags, NEXTHOP_FLAG_FIB)
for route installation. Please note it does do it for a mpls
labeled route installation, which will be fixed in a future
commit.

When BGP is being redistributed prefixes, allow it to
understand the nexthop type.
This fixes the issue where a blackhole route was being interpreted
to having a nexthop of 1.0.0.0( ruh-roh!!! ). This broke
downstream neighbors as that they would receive a 1.0.0.0 nexthop,
which is bad, very very bad.
This commit sets us up for the future where we can match
a route-map against a nexthop type. In that bgp is
now at least nominally paying attention to the type.

RIP is not using the nexthop data structure and as such when

types.

This code modifies zebra to use the STREAM_GET functionality.
This will allow zebra to continue functioning in the case of
bad input data from higher level protocols instead of crashing.
Signed-off-by: Donald Sharp <sharpd@cumulusnetworks.com>
Currently when stream reads fail, for any reason, we assert.
While a *great* debugging tool, Asserting on production code
is not a good thing. So this is the start of a conversion over
to a series of STREAM_GETX functions that do not assert and
allow the developer a way to program this gracefully and still
clean up.
Current code is something like this( taken from redistribute.c
because this is dead simple ):
afi = stream_getc(client->ibuf);
type = stream_getc(client->ibuf);
instance = stream_getw(client->ibuf);
This code has several issues:
1) There is no failure mode for the stream read other than assert.
if afi fails to be read the code stops.
2) stream_getX functions cannot be converted to a failure mode
because it is impossible to tell a failure from good data
with this api.
So this new code will convert to this:
STREAM_GETC(client->ibuf, afi);
STREAM_GETC(client->ibuf, type);
STREAM_GETW(client->ibuf, instance);
....
stream_failure:
return;
We've created a stream_getc2( which does not assert ),
but we need a way to allow clean failure mode handling.
This is done by macro'ing stream_getX2 functions with
the equivalent all uppercase STREAM_GETX functions that
include a goto.
