tcpdump uses that symbol directly:
/*XXX from libbpfc.a */
extern struct eproto {
char *s;
u_short p;
} eproto_db[];
static void
init_eprotoarray(void)
{
int i;
struct hnamemem *table;
for (i = 0; eproto_db[i].s; i++) {
int j = ntohs(eproto_db[i].p) & (HASHNAMESIZE-1);
table = &eprototable[j];
while (table->name)
table = table->nxt;
table->name = eproto_db[i].s;
table->addr = ntohs(eproto_db[i].p);
table->nxt = newhnamemem();
}
}
The result is a (harmless) warning:
tcpdump:tcpdump: /usr/lib/libpcap.so.8.2 : WARNING: symbol(eproto_db) size
mismatch, relink your program
It would probably be nice to stop using directly this from tcpdump, and
to hide that stuff using the Symbols.list infrastructure. But for now
I think that a minor bump is better than nothing.
