This should be fixed by rev 1.1.1.5 of src/contrib/libpcap/inet.c . Bill To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-current" in the body of the message

I guess this is http://www.tcpdump.org/cgi-bin/cvsweb/libpcap/inet.c?r1=1.25&r2=1.26 The easiest thing to do is probably cvs import their rev 1.26 of inet.c . Shall I do this? Bill To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-current" in the body of the message
Re: trafshow doesn't work?
[ Bill Fenner added as "maintainer" of libpcap/tcpdump ] According to Kris Kennaway: > Fallout from the malloc.conf changes. tcpdump has the same bug. I think^W'm sure the bug is in libpcap though as several libpcap applications fail with the same error (tcpdump, ntop, trafshow). The problem is inside pcap_lookupdev(), "buf" is used to store interface data, then freed then the buffer is used again : -=-=- for (;;) { buf = malloc (buf_size); if (buf == NULL) { close (fd); (void)sprintf(errbuf, "out of memory"); return (NULL); } ifc.ifc_len = buf_size; ifc.ifc_buf = buf; memset (buf, 0, buf_size); ... for (cp = ifrp->ifr_name; !isdigit(*cp); ++cp) continue; n = atoi(cp); if (n < minunit) { minunit = n; mp = ifrp; } } free(buf); <<< (void)close(fd); if (mp == NULL) { (void)strcpy(errbuf, "no suitable device found"); return (NULL); } (void)strncpy(device, mp->ifr_name, sizeof(device) - 1);<<< device[sizeof(device) - 1] = '\0'; return (device); -=-=- The last free(buf) has filled "buf" with 0xd0 so "mp" points to the same area. If anyone has the address of the mailing list for libpcap, please send this patch. I won't commit it as it would get the file out of the vendor branch.

trafshow doesn't work?
Hi! There, My trafshow doesn't work. Whenever I tried to run trafshow, it gave me error message says, "trafshow: : Device not configured" I check my Kernel configuration file, a line "device bpf 4 #Berkeley packet filter" is there and device drivers bpf0, bpf1, bpf2, and bpf3 are in /dev. I don't know whatelse I should configure. Can someone help me? My OS is FreeBSD 5.0-CURRENT #21. Thanks!
