Package: isc-dhcp-client
Version: 4.3.1-5
Severity: important
Hello,
Running
dhclient -6 -r
basically hangs for one minute before returning. Running
dhclient -1 -6 -r
does finish. dhclient.c reads as
if (release mode) {
#ifndef DHCPv6
return 0;
#else
if (local_family == AF_INET6) {
if (onetry)
return 0;
} else
return 0;
#endif /* DHCPv6 */
}
I don't really understand why looking for -1 (onetry) in the inet6 case,
I don't see anything in the documentation, and what I understand from
the source code is that in that case, since -r is specified no request
will be sent, and thus no answer will be received, and thus dhclient
will just wait for the timeout (one minute) without doing anything.
This affects d-i's netcfg finish-install script on !linux ports, where
it runs both dhclient -r and dhclient -6 -r. One way to workaround
the issue for now is adding -1 to netcfg. It happens that it doesn't
hit kfreebsd just because it happens that umount -a in the 95umount
finish-install script manages to kill dhclient for some reason...
