* (general) More solaris PF_ROUTE hacks. The IFF_UP mangling
for solaris was incomplete on the PF_ROUTE side. fix it.
This changeset generally uglifies things. For some future
work I'd like to see the state changes seperated out from
the details of the code. Differences between systems might
then be slightly easier to implement without convoluted
hacks.
Changes should be specific to Solaris mostly, however
also tested on FreeBSD 6.
* if_ioctl_solaris.c: (interface_list_ioctl) ignore ~IFF_UP
interfaces, we'll hear about them when/if interface goes up
through NEWADDR.
Update flags explicitely at end of it to kick mangling.
* ioctl_solaris.c: (if_mangle_up) removed to interface.c, in
kind.
(lifreq_set_name) more convenient to take the string, than
the ifp.
(if_get_flags_direct) new convenience function, returns
the actual flags. Used during bootstrap in if_ioctl_solaris.c
to peek at flags of logical interfaces to see whether or
not to ignore them.
(if_get_flags) ENXIO means it's gone, poke out IFF_UP and
kick flags update.
(if_{un,}set_flags) flags argument should be 64bit.
* ioctl.{c,h}: flags argument should be 64bit.
* interface.h: Add a 'primary_state' flag to struct zebra_if on
SUNOS_5.
Export if_flags_update.
* interface.c: (if_flags_mangle) moved over in kind from
ioctl_solaris.c. Nasty kludge to try get IFF_UP right, as
much as is possible. Also keep track of the actual IFF_UP
value for the primary interface, so we can know when the ifp
must be deleted.
(if_flags_update) Take a new interface flags value, apply it
to the interface, and take whatever actions are required due
to flag transitions.
(if_refresh) flag state change logic is moved out to
previous. Just call if_get_flags, which will end up using
previous to effect the update of flags.
(if_flag_dump_vty) IFF_IPV{4,6} aren't interesting, VIRTUAL
and NOXMIT are though.
* kernel_socket.c: (ifm_read) Down->Down transitions shouldn't
create ifp, for non-IFANNOUNCE systems.
Use if_flags_update to update flags.
flag transition logic is now handled automatically through
if_flags_update.
(ifam_read) Better to call if_refresh *after* adding
connected addresses, as connected count affects IFF_UP on
IFF_UP-mangled systems.
On Solaris, Up->Down due to DELADDR means we need to delete
the ifp - the IFINFO might already have been and gone.
* rt.h: include other dependent headers.

* connected.{c,h}: Include memory.h
(connected_add_ipv4) Use MTYPE for ifc label.
(connected_add_ipv6) Also should accept label. Store it in ifp.
(connected_del_ipv4) Taking label as argument is pointless.
* rt_netlink.c: (netlink_interface_addr) update label usage
for connected_{add,delete} functions.
* if_ioctl.c: (if_getaddrs) NULL label for connected_add_ipv6.
* if_ioctl_solaris.c: (interface_list_ioctl) Pass LIFC_NOXMIT
so we also find out about NOXMIT interfaces like VNI.
Bit of hackery to turn interface names into the primary
interface name, later with routing socket messages we only
will about primary interfaces anyway, so we must normalise
the name.
(if_get_addr) take label as argument, so it can
be passed to connected_add.
If label is provided, then it is interface name to issue the
ioctl for address information on, not the ifp name.
(interface_list) List AF_UNSPEC too, just in case.
* if_proc.c: (ifaddr_proc_ipv6) label for connected_add_ipv6.
* interface.c: (if_addr_wakeup) Some very bogus code - sets
IFF_RUNNING - add comment.
(if_refresh)
(ip_address_install) Use MTYPE for ifc label.
* ioctl_solaris.c: (if_mangle_up) New function. Hackery to make
IFF_UP reflect whether any addresses are left on the
interface, as we get signalled for IFF_UP flags change on the
primary interface only. Logical interfaces dont generate
IFINFO, but we do get an RTM_DELADDR.
(if_get_flags) Call if_mangle_up before return.
* kernel_socket.c: (ifam_read) Fixup calls to
connected_{add,delete} to match above changes. Rename gate
variable to brd, less confusing.
Pass the interface name as a label, if it is not same name
as ifp->name.

* if_ioctl_solaris.c: (interface_list_ioctl) Save errno before calling
zserv_privs.change.
* ioctl{,_solaris}.c: (if_ioctl,if_ioctl_ipv6) Save errno before calling
zserv_privs.change.

[backport candidate]

* global: Replace strerror with safe_strerror. And vtysh/vtysh.c
needs to include "log.h" to pick up the declaration.
|

* if_ioctl_solaris.c: HAVE_IPV6 ifdef fixups
* zserv.c: ditto
* ioctl_solaris.c: ditto.
* interface.c: cast for LLADDR
* interface.h: Add guards, include redistribute.h and remove
extraneous definitions of zebra_interface_{up,down}_update
* ioctl.h: Add AF_IOCTL define for non SOLARIS_IPV6
* redistribute.h: include dependent header, zserv.h
* zserv.h: include dependent header, rib.h

* Makefile.am: support for IOCTL_METHOD, as per Sowmini's patch.
* if_ioctl_solaris.c: Fixup some erroneous privilege changes and
add privs.h header.
