All daemons modified to support custom path to zserv
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.
Second patch replaces "VTY_GET_LONG ("AS", as_ul, arg);"
by "VTY_GET_INTEGER_RANGE ("AS", as, arg, 1, BGP_AS4_MAX);"
as done in all other code, which parses AS numbers.
ospf6_routemap_rule_match_interface* was imported from ospfd
daemon with minor changes. new CLI options defined.
`ospf6_routemap_rule_match_interface' was changed to support
IPv6 (ospfv3) route's external information.
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
https://bugzilla.vyatta.com/show_bug.cgi?id=4421
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.

if update-source was given as interface name, bgpd was unconditionally
trying to bind to an IPv4 address from that interface.
change function to find the best-matching (number of address bits)
same-family address on the interface.
* ospf6_message.c: (ospf6_packet_max): new function, return maximum IPv6
payload on an interface; (ospf6_hello_send, ospf6_dbdesc_send,
ospf6_dbdesc_send_newone, ospf6_lsreq_send, ospf6_lsupdate_send_neighbor,
ospf6_lsupdate_send_interface, ospf6_lsack_send_neighbor,
ospf6_lsack_send_interface): compare message size with the maximum
payload instead of the MTU.
To set the TOS bits on TCP connections, platforms that restrict
capabilities need the priv level to be raised before the sockopt
is set, and this requires the ZCAP_NET_ADMIN priv.
* bgp_main.c: update _caps_p to include ZCAP_NET_ADMIN
* bgp_network.c
* bgp_connect(): request ZPRIVS_RAISE/ZPRIVS_LOWER
* bgp_listener(): request ZPRIVS_RAISE earlier
Commit 05a4936b713b9882171d0f7fb20b8439df23939e fixed some of the
attributes involved, but not all. This commit should do it.

bgp_notify_send_with_data() directly, but master branch assumes
using bgp_attr_malformed().

IPv6 supports the same concept of differentiated service for routing
protocols as IPv4, but like too many things, the standards committee
decided that having two names for the same thing wasn't good enough and
introduced a third more generic term transport class.
The socket option to set transport class works the same as IPv4, but the
arguments are different.

* ripngd/ripngd.c
* ripng_make_socket(): set socket option
Commit 2febf323411c1aed9d7694898f852ce2ef36a7e5 assumed every flag
bit except optional/transitive/partial unset, which at times could
not be true for "extended length" bit.

"While setting up a testbed, I ran across a little problem in the
parsing of the "graceful restart" BGP capability that resulted in
Quagga not actually activating it for the peer in question - when
the peer sent a single AFI/SAFI block."

* bgp_capability_restart(): actually process the last AFI/SAFI block
* bgp_attr.c
* bgp_attr_parse(): provide extra argument to bgp_attr_aggregator()

Do not check each of the Optional/Transitive/Partial attribute
flag bits, when their only valid combination is known in advance,
but still perform bit-deep error message logging. This change
assumes unused (low-order) 4 bits of the flag octet cleared.

ORIGIN handling function used to have "partial" bit check and recent
commits added it for NEXT_HOP, MULTI_EXIT_DISC and ATOMIC_AGGREGATE
cases. This commit adds "partial" check for AS_PATH and LOCAL_PREF
cases, which should leave attributes 1 through 6 inclusive completely
covered with attribute flags checks.
* bgp_attr.c
* bgp_attr_origin(): use bit-by-bit checks for better diagnostics
* bgp_attr_aspath(): add flag check

* lib/prefix.h
* IPV4_CLASS_DE(): new helper macro

reporting, explain meaning of RFC4271 section 6.3 and implement it

- SAFI value 3 is reserved. It was assigned by RFC 2858 for a use
that was never fully implemented, so it is deprecated by this
document.
* zebra.h: rename macro
* bgp_fsm.c: (bgp_graceful_restart_timer_expire,
bgp_graceful_stale_timer_expire, bgp_stop, bgp_establish): update
* bgpd.c: (peer_nsf_stop): update
* bgp_open.c: (bgp_capability_vty_out): SAFI 3 isn't a recognized case
any more
