dhcp6c's Issues

Core dump when HUP - Only happens when RAW options are in use.

Kev picked this one up, Seems that he noticed issues when his LAN connection was flapping due to a faulty cable. He was getting strangeness in one of the options being sent by dhcp6c. It was fine on the initial run but if a SIGUP was sent ( LAN or WAN flap ) then one of the options showed a corrupted string.

I tried it on my test unit, adding the options in advanced etc and in my case dhcp6c exited with SIGBUS error and a dhcp6c.core for me to look at. Tracing that and the logs appears to show it's trying to free memory that it should not. Looking through the source there is a call at line 151 in common.c -

free(op); // Needed?

I have commented this out and re-compiled and now the error does not occur.
op is a pointer to a structure and I think the function TAILQ_REMOVE(head,op,link) call already frees the pointed to structure,

Thoughts?

Sent a version to Kev for testing on his OR France system to see if it fixes it.

Building DHCP6c from source code fails.

segfault

i told you what exactly is wrong and never blamed you how bad you are. so fix it or keep it as is. i'm not interested of sending pull requests to people who are not accepting that there might be a bug. i described it really in detail and the difference between pointers and numeric 64 bit values should be clear to any programmer . thanks.

Wrong advertized link layer address?

The link layer address advertised with the SOLICIT request is not the one of the interface I run dhcp6c on. It's the address of an unrelated interface. It's neither WAN, neither LAN.

Any idea how that could happen? Not sure which of the two is the problem. The configuration:

profile default
{
  information-only;

  request domain-name-servers;
  request domain-name;

  script "/etc/wide-dhcpv6/dhcp6c-script";
};


interface internet0 {
  send ia-pd 3337356211;
  request domain-name-servers;
  request domain-name;
  request ntp-servers;
  script "/etc/wide-dhcpv6/dhcp6c-script";
};

id-assoc pd 3337356211 {
 prefix-interface br0 { #internal facing interface (LAN)
    sla-id 1; 
    ifid 1; 
    sla-len 8;
    };
  };

Get delegated prefix information in script

Is there a way to get information about delegated prefixes passed to the script?

I'm running a system where 2 prefix are delegated:

The first is normal /64 prefix that I'm attaching to an interface for normal SLAAC address allocation.
The second is a /96 or /120 that I'm using for 464XLAT that I need to pass to an instance of Jool running on the router. At the moment I'm having to hardcode/manually enter this.

If not can I ask for it to be a feature request?

ia-pd and ia-na T1 and T2 values

Is there any way to set the T1 and T2 values for ia-pd and ia-na options?

The doco doesnt seem to have a way, im about to dive in to the code...

Issues with load all interfaces patches

I'm running into some issues I'm not sure the cause of when trying to use the opnsense patches to load all interfaces in the config instead of requiring them on the command line. It causes sigbus/segfaults on OpenBSD and I'm not sure why. I'm getting 0xdfdfdfdfdfdfdfdf as the pointer being passed into:

ifinit (ifname=0xdfdfdfdfdfdfdfdf <Address 0xdfdfdfdfdfdfdfdf out of bounds>)

From the initial loop in main. Which is usually a sign of a free after use or similar issue on OpenBSD's malloc/free implementation. I've been staring at this longer than I'd like to admit and I'm not really seeing why this is happening. I'm also confused as to why cfparse() needs to be called on either side of that interface name loading.

The patch also makes specifying interfaces on the command line only work until the next SIGHUP which I submitted #30 to fix. With #30 the code runs and works on OpenBSD so long as interfaces are passed on the command line. Without #30 when passing interfaces on the command line a sigbus/segfault will also happen on SIGHUP as if an interface was not specified on the command line at startup.

Parsing configuration failed at startup if request is tracked by a bridged interface

Hi,

I'm using OPNSense following this setup : https://wiki.opnsense.org/manual/how-tos/orange_fr_fttp.html

My box is set up as :

igb0 as WAN
igb1, igb2, igb3… as bridge0
bridge0 as LAN

On startup, dhcp6c client parses the config file and see that my LAN interface (bridge0) is tracking the WAN interface to get IPv6 configuration, but bridge0 is not set up at this moment, so the config fails and dhcp6c didnt start.

Jan  8 20:19:12 opnsense dhcp6c[38999]: /var/etc/dhcp6c_wan.conf:13 invalid interface (bridge0): Device not configured
Jan  8 20:19:12 opnsense dhcp6c[38999]: called
Jan  8 20:19:12 opnsense dhcp6c[38999]: failed to parse configuration file

I need to force a dhcp refresh after startup to get IPv6

How to reproduce :

set up a WAN interface with dhcp6c
set up a LAN interface with bridge on multiple physical interfaces
set up id-assoc to the bridge interface

id-assoc pd 0 {
  prefix-interface bridge0 {
    sla-id 0;
    sla-len 8;
  };
};

reboot
see logs

What expected :

no errors during boot, ipv6 working directly

[support] IPV6 prefix update causes loss of IPV6 connection

Describe the bug

In my use of opnsense, the IPV6 connection often disconnects after a few days (not at a fixed time).
The problem occurs when I can see from the opnsense admin page that the device from the ISP has assigned a different IPV6 prefix to the WAN, but the LAN is still using an old IPV6 prefix.
At this point no other device connected to the LAN can access the internet via IPV6, whereas the opnsense unit can access the IPV6 public address.

I believe the problem is caused by my ISP assigning new IPV6 prefixes from time to time and opnsense not being able to update the IPV6 prefixes on the LAN.

I turned on the debug log for dhcp6c.Here's the log when the problem happened.

Looking at the LOG, the problem occurs at “2024-07-18T21:59:23” and the ISP doesn't seem to have assigned us any IPV6, but according to the admin page, the WAN does get a new IPV6 prefix.

After a problem occurs, PCs accessing the LAN can only access the opnsense LAN

If you reset or reload the WAN interface after the problem occurs, it returns to normal.

Expected behavior

Losing IPV6 connectivity at irregular intervals is annoying, and the behavior I would expect should be that you shouldn't lose IPV6 connectivity altogether after changing prefixes.

Environment

OPNsense 24.1.10_3-amd64
Dell Optiplex 3070 MFF
Intel(R) Core(TM) i3-8100T CPU @ 3.10GHz (4 cores, 4 threads)
Network card:

Realtek NIC (LAN)

Full Debug output is not being sent to syslog.

if '-D' is used to get full debug output only normal debug output is sent, running from the shell in foreground mode then full debug output can be seen. Has there been a syslog change that may have affected this?

Typo

dhcp6c/dhcp6c.c

Line 1067 in 162461f

"failed to add an IAPD");

Should be "Failed to add IANA"

segfault

a 100% segfault on big endian is the missuse of a long long number for pointers in the config parser for the rawoption option number. this will crash on and mips big endian system. use "long" or use a string or even use a numeric value. but never use 64 bit integers as casted pointer here.

Patch request - ignore advertise messages with none of requested data and missed status codes

I was hoping to get a sense of whether a wide-dhcpv6 patch that was introduced in the upstream in 2015 will make it into OPNsense.

The issue is this (as explained to me by my ISP). Whenever dhcp6c on OPNsense sends a release to my ISP, and then (as is usual) tries to send a solicit straight after the release to obtain a new lease, the ISP's BNG responds with a DHCPv6 UnspecFail advertise. Apparently, somewhere between the DHCPv6 proxy and DHCPv6 server running on the BNG, the release process has not been finalised (and so the lease is not considered available to the client again) when dhcp6c sends the new solicit, hence the UnspecFail response.

However, dhcp6c does not interpret this correctly and instead assumes the BNG is trying to advertise the prefix, and so dhcp6c sends a DHCPv6 request for a blank prefix back to the BNG. The BNG of course drops this as invalid. dhcp6c then eventually gives up trying to get a DHCPv6 lease, and accordingly no WAN GUA or IPv6 PD is received, until dhcp6c is reloaded or restarted.

The behaviour can be seen in these logs (anonymised):

The BNG's behaviour (my ISP uses Cisco routers) is actually RFC compliant, according to my ISP (and I understand Cisco, with whom my ISP has apparently been discussing the issue). Per RFC 3315 (https://tools.ietf.org/html/rfc3315#section-15):

If a server receives a message that contains options it should not contain (such as an Information-request message with an IA option), is missing options that it should contain, or is otherwise not valid, it MAY send a Reply (or Advertise as appropriate) with a Server Identifier option, a Client Identifier option if one was included in the message and a Status Code option with status UnSpecFail.

Same for the updated RFC 8415 (https://tools.ietf.org/html/rfc8415#section-16):

If a server receives a message that it considers invalid, it MAY send a Reply message (or Advertise message, as appropriate) with a Server Identifier option (see Section 21.3), a Client Identifier option (see Section 21.2) (if one was included in the message), and a Status Code option (see Section 21.13) with status UnspecFail.

The issue of wide-dhcpv6 / dhcp6c not responding correctly to UnspecFail advertises was, I am told, addressed in the upstream. My research suggests that occurred in 2015: https://sourceforge.net/p/wide-dhcpv6/bugs/34/. Specifically, item 4:

4) dhcpv6: ignore advertise messages with none of requested data and missed status codes.

This patch was implemented in Debian in March 2018: https://metadata.ftp-master.debian.org/changelogs//main/w/wide-dhcpv6/wide-dhcpv6_20080615-23_changelog. Specifically, patch 0018:

- Add patch 0018 to ignore advertise messages with none of requested data and missed status codes.
Thanks to Roman Mamedov for the report and Evgeniy Manachkin for the patch (Closes: #765453).

What I understand to be the content of the patch is attached: 0018-dhcpv6-ignore-advertise-messages-with-none-of-reques.patch.txt

My ISP tells me that they believe Netcomm has implemented the patch, and I have seen comments from Ubiquiti on their forums that they plan to implement the patch, at least for their Edgerouter line.

But this patch does not appear to have made it into FreeBSD or OPNsense.

Curiously, some of the items addressed by the upstream patch in 2015 have been implemented - in FreeBSD in Jan 2016 (based on the descriptions in https://www.freshports.org/net/dhcp6 for version 20080615_4) and in OPNsense in December 2016 (based on the commit descriptions in https://github.com/opnsense/dhcp6c/commits/master). But not item 4.

Is there any prospect of this patch being implemented in OPNsense?
