IPV4_ADDR_SAME() wasn't passed the right union member, this could cause
a bug due to strict-aliasing. IPV6_ADDR_SAME() case got its fix before
the error could be created by macro upgrade.

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.

ip_masklen() was likely to return incorrect results after being compiled
with -fstrict-aliasing (-O2, -O3, -Os)
|
|
The new implementation makes use of a 64KB mapping table, which makes it
possible to compute masklen faster and with constant execution time. The
map also allows for additional version of the function, which can detect
errors in input argument.
The previous implementation had a variable cost of execution, which
depended on masklen in a non-linear manner, and at its worst (/31) was
4 times slower, than the new implementation. The only case of old
function just slightly outperforming the new one is /0, which is of
little practical interest.

* ospf_abr.c
* ospf_abr_nssa_am_elected(): feed "best" instead of "address of best"
into IPV4_ADDR_CMP(), because "best" is a pointer; also, mean s_addr
field of the structures to get better typed pointers

The if_dump code had empty loop, that caused set-never-used warning.
|
|
Stephen Hemminger's commits contain all the changes and
several other warning fixes.
This reverts commit 6947dbebdc91b6272f8107a6e0dd211457438606.

Make progname a string, and cast when calling asn1.
Remove variable set but never used.
|
|
Check result of fgets(), and don't set variable that is
never used.
|

When doing valgrind testing, the privledges from zprivs_init() need
to be cleaned up on exit.

The code for nssa_range and other bits that were written but
never used.

BGP was ignoring nexthop info for static and other redistributed
routes for IPv6. Build extra attribute info to store the nexthop.

The old algorithim looked up every node twice as it withdrew
the entry. It looks up entry once in redistribute_withdraw, then
looks it up again info_delete. Use result of first lookup
to do the free directly.
This may explain the slow performance observed in

Change sockunion_log() to not use strdup(). This fixes a small memory
leak that occurs on every failed connect(), and is simpler/cleaner.
|
|
The delete_hook was being run after calling access list delete function.
This would cause ospf to dereference a NULL, in ospf_filter_update
because 'access->name' was already freed.

Experience with IPv4 counterpart of this function suggests, that
this way of type-punning is likely to cause errors.

(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 is needed to avoid stale routes in some cases; the regression was
introduced by commit 1d19234e79c77a7d55194b513f2a77c6a691bc2c.
* ospf6_spf.c: (ospf6_spf_calculation) Call ospf6_spf_table_finish()
before possibly returning if no router-LSA is found for the root of
the SPF tree.

This issue has been pointed out by Lou Berger and Tim Browski.

As long as ospf6_packet_examin() is now the single checkpoint for
received packets, most of the old checks performed elsewhere can
be converted into assert() constructs. Malformed input data at
respective points can be attributed solely to a programming error,
not a malformed packet.

getaddrinfo returns a list of socket parameters for listening. it
will contain both IPv4 and IPv6 listening sockets. unless we use
IPV6_V6ONLY on the IPv6 ones, only the socket listed first will
work. if the IPv4 one came first, the IPv6 one would get an
"Address in use" error.
this functionality was already present for bgpd and its listening
sockets. as it is needed for vtys as well, make it a common helper.

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.

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)

MALLOC/REALLOC aren't used properly (no rpl_malloc), remove them
while at it, infer some sane ipforwarding method from the OS value.
(v2 on that, "==" is not a proper operator for standard "test")

* 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().

socket.
lib: generalize a zclient connection
zclient_socket_connect added. zclient_socket and
zclient_socket_un were hidden under static expression.
"zclient_serv_path_set" modified.
