ip6mr: limit IPv6 MRT_TABLE identifiers

2013-01-28T00:31:03+00:00

We did this for IPv4 in b49d3c1e1c "net: ipmr: limit MRT_TABLE
identifiers" but we need to do it for IPv6 as well.  On IPv6 the name
is "pim6reg" instead of "pimreg" so there is one less digit allowed.

The strcpy() is in ip6mr_reg_vif().

ip6mr: fix rtm_family of rtnl msg

2012-12-04T18:27:24+00:00

We talk about IPv6, hence the family is RTNL_FAMILY_IP6MR!
rtnl_register() is already called with RTNL_FAMILY_IP6MR.

The bug is here since the beginning of this function (commit 5b285cac3570).

ip6mr: advertise new mfc entries via rtnl

2012-12-04T18:08:11+00:00

This patch allows to monitor mf6c activities via rtnetlink.
To avoid parsing two times the mf6c oifs, we use maxvif to allocate the rtnl
msg, thus we may allocate some superfluous space.

ipmr/ip6mr: allow to get unresolved cache via netlink

2012-12-04T18:08:11+00:00

/proc/net/ip[6]_mr_cache allows to get all mfc entries, even if they are put in
the unresolved list (mfc[6]_unres_queue). But only the table RT_TABLE_DEFAULT is
displayed.
This patch adds the parsing of the unresolved list when the dump is made via
rtnetlink, hence each table can be checked.

In IPv6, we set rtm_type in ip6mr_fill_mroute(), because in case of unresolved
mfc __ip6mr_fill_mroute() will not set it. In IPv4, it is already done.

ipmr/ip6mr: report origin of mfc entry into rtnl msg

2012-12-04T18:08:11+00:00

A mfc entry can be static or not (added via the mroute_sk socket). The patch
reports MFC_STATIC flag into rtm_protocol by setting rtm_protocol to
RTPROT_STATIC or RTPROT_MROUTED.

ipmr/ip6mr: advertise mfc stats via rtnetlink

2012-12-04T18:08:10+00:00

These statistics can be checked only via /proc/net/ip_mr_cache or
SIOCGETSGCNT[_IN6] and thus only for the table RT_TABLE_DEFAULT.
Advertising them via rtnetlink allows to get statistics for all cache entries,
whatever the table is.

using standard helpers.

netconf: advertise mc_forwarding status

This patch advertise the MC_FORWARDING status for IPv4 and IPv6.
This field is readonly, only multicast engine in the kernel updates it.

ipv4/ipmr and ipv6/ip6mr: Convert int mroute_do_ to bool

2012-11-25T21:34:17+00:00

Save a few bytes per table by convert mroute_do_assert and
mroute_do_pim from int to bool.

Remove !! as the compiler does that when assigning int to bool.
