Hi,

Several pfSense users report IPv6-related panics when an = interface is deleted.
The relevant bug reports are https://redmine.pfsense.org/issues/14164 and https://redmine.pfsense.org/issues/= 14431.
The latest report is for a build that includes commits up to 1a18383a52bc= 373e316d224cef1298debf6f7e25 (=E2=80=9Clibcrypto: link engines and the le= gacy provider to libcrypto=E2=80=9D, September 15th).

I believe all reports are for users running PPPoE, via ne= tgraph, but that might be coincidental, as that=E2=80=99s the most likely= way for interfaces to be destroyed (when PPP disconnects and reconnects)= =2E

There are a few different backtraces, but they appear to = have the same root cause, so I=E2=80=99ll focus on one of them:

My understanding is that the fib table should get updated= whenever we change the routing table (such as during interface cleanup i= n if_detach= _internal()). Some quick experimentation with epair and dtrace als= o shows:

              kernel`0xffffffff8102315b

In other words, when we delete the interface if_detach_internal() purges the interface addresses, which ends up rebuilding the fib (rebuild_fd()) via r= ib_del_route().
That ought to ensure that we cannot end up finding this struct ifnet thro= ugh fib6_lo= okup(), as the purging of the addresses (and thus the rebuilding o= f the fib) is done before we if_domdetach() at the end of if_detach_internal(), a= nd the NULL afdata[AF_INET6] demonstrates that we=E2=80=99ve gotten there= =2E

We=E2=80=99ve also gone through if_free(), as the ifindex_tab= le no longer contains the struct ifnet pointer for the relevant interface= =2E
We appear to have not yet called if_free_deferred() (and indeed, ifp->if_r= efcount is 4, so we wouldn=E2=80=99t have called that yet).

I=E2=80=99m confused as to how this can happen, and would= appreciate hints.

Hi,

Several pfSense users = report IPv6-related panics when an interface is deleted.
The relevant bug reports are https://redmine.pfsense.org/issues/14164 and https://redmine.pfsense.org/issues/14431.
The latest report is for a build that includes commits up to = 1a18383a52bc373e316d224cef1298debf6f7e25 (=E2=80=9Clibcrypto: link = engines and the legacy provider to libcrypto=E2=80=9D, September = 15th).

I believe all reports are for users = running PPPoE, via netgraph, but that might be coincidental, as that=E2=80= =99s the most likely way for interfaces to be destroyed (when PPP = disconnects and reconnects).

There are a = few different backtraces, but they appear to have the same root cause, = so I=E2=80=99ll focus on one of them:

This happens in the TCP output = path, where we look up the hop limit for a specific destination. I=E2=80=99= ve obtained a core dump for such a crash, and I believe the panic = happens on line https://cgit.freebsd.org/src/tree/sys/netinet6/in6_src.c#n861

The call in tcp_default_output() is = in6_selecthlim(int, NULL);, so we don=E2=80=99t get an = ifp from the caller, but instead perform a route lookup, and try to = obtain the hop limit through ND_IFINFO(nh->nh_ifp). = This panics because the afdata[AF_INET6] pointer is NULL. The core dump = shows a deleted structure ifnet:



`egrep -r 'if_afdata\[AF_INET6\]\s*[!=3D]=3D\s*NULL' = sys/netinet6'` shows there're many places do the NULL check. I think we = can do it in in6_selecthlim() as a = workaround.

My understanding is that the fib = table should get updated whenever we change the routing table (such as = during interface cleanup in if_detach_internal()). = Some quick experimentation with epair and dtrace also shows:

In other words, when we delete = the interface if_detach_internal() purges the interface = addresses, which ends up rebuilding the fib (rebuild_fd()) via = rib_del_route().
That ought to ensure that we cannot end up finding this struct ifnet = through fib6_lookup(), as the purging of the addresses (and = thus the rebuilding of the fib) is done before we if_domdetach() = at the end of if_detach_internal(), and the NULL = afdata[AF_INET6] demonstrates that we=E2=80=99ve gotten there.



By intuition, fib6_lookup() should not return = **INVALID** next hop (with detaching interfaces), unless explicitly = requested.

We=E2=80=99ve also gone through if_free(), as the ifindex_table no longer contains the = struct ifnet pointer for the relevant interface.
We appear to have not yet called if_free_deferred() (and = indeed, ifp->if_refcount is 4, so we wouldn=E2=80=99t have called = that yet).

I=E2=80=99m confused as to how = this can happen, and would appreciate hints.



I believe Alexander has insight on this.

Thanks,
Kristof

Assume we run some FreeBSD-based broadband remote access server for PPPoE (net/mpd5 for example). The server has hundreds or thousands vlan interfaces and even more ngXXX interfaces, one per user PPPoE session. The server software may need to enable its PPPoE service for all newly created vlans over another "physical" parent interface just configured in addition to already running ones. I see no effective userland API for the software to list vlan interfaces under specific parent one. The only option I see is getifaddrs(3) function to get list of ALL interfaces in the system then iterate over the list calling ioctl SIOCGETVLAN and if there is no error, compare returned vlr_parent name with the name of needed parent interface. Not efficient at all, while serving new PPPoE connection attempts simultaneously, collecting traffic stats for RADIUS accounting etc. Do I miss something?
