The multicast messages are coming from src/sys/netinet/if_ether.c.
Reviewing that code:
http://svnweb.freebsd.org/base/stable/9/sys/netinet/if_ether.c
r241992 catches my eye, referring to the sysctl named
net.link.ether.inet.allow_multicast, which defaults to 0. Note
the commit message, however:
Merge 240073 from head:
Provide a sysctl switch that allows to install ARP entries
with multicast bit set. FreeBSD refuses to install such
entries since 9.0, and this broke installations running
Microsoft NLB, which are violating standards.
Tested by: Tarasov Oleg <oleg_tarasov sg-tea.com>
The relevant logging line code is:
549 if (allow_multicast == 0 && ETHER_IS_MULTICAST(ar_sha(ah))) {
550 log(LOG_NOTICE, "arp: %*D is multicast\n",
551 ifp->if_addrlen, (u_char *)ar_sha(ah), ":");
552 return;
553 }
Where allow_multicast correlates directly with the aforementioned
sysctl, and ETHER_IS_MULTICAST is a macro in src/sys/net/ethernet.h
73 #define ETHER_IS_MULTICAST(addr) (*(addr) & 0x01) /* is address mcast/bcast? */
I'm not familiar with what ar_sha() does, but the macro checks to see if
the dereferenced value has bit 0 set or not.
I do not think setting net.link.ether.inet.allow_multicast=1 would
alleviate the mbuf issue, based on the code I've looked at. I do see
some code in src/sys/net/if_ethersubr.c that relates to mbufs and
ETHER_IS_MULTICAST() conditions, however.
I'm CC'ing the committer, Gleb Smirnoff, who might have some more
insights on what's going on here, where in the kernel the leak may be,
and/or how to track it down.
