That sounds like an outright bug. Looks like it was true in 14.0 as well= =2E Is there a bug report? I couldn't find one. btw, UPDATING is meant for upgrades from source.

For example, e6000sw creates such struct ifnets for each of its ports s= o it can call into the MII code. If there is then a link state event this calls do_link_state_change() -> rtnl_handle_ifevent() -> dump_iface() -> get_operstate() -> get_operstate_ether(). That wants to know if the link is up or down, so= it tries to ioctl(SIOCGIFMEDIA), which doesn't go well if if_ioctl is NULL. Guard against this, and return EOPNOTSUPP.

    alc(4): disable MSI-X by default on Killer cards

    Several users with alc(4)-based "Killer" Ethernet cards have reported
    issues with this driver not passing traffic, which are solved by
    disabling MSI-X using the provided tunable.

    To work around this issue, disable MSI-X by default on this card.

    This is done by having msix_disable default to 2, which means
    "auto-detect".  The user can still override this to either 0 or 1 as
    desired.

    Since these are slow (1Gbps) Ethernet ICs used in low-end systems, it's
    unlikely this will cause any practical performance issues; on the other
    hand, the card not working by default likely causes issues for many new
    FreeBSD users who find their network port doesn't work and have no idea
    why.

Please see also bug 277063. Perhaps it has already been fixed[1]. Could you
test if the panics are reproducible on 14.1-BETA3 ?

Hi,

sorry, I cannot dump; this is a diskless and netdump does not do IPv6;
needless to say that would be funny in this case anyway; unfortunately
I have also already re-compiled the kernel so I can only look things up approx.

FreeBSD main from May 13 (f3eeeb959c9b00c89a2e1ff009c78162eb398656).

I assume we lost the ifp from a destroy of a cloned interface in ip6_output()
between lines 806 and 811?

I'm not quite sure, but it seems the `ifp` is not fully constructed. See =
https://cgit.freebsd.org/src/tree/sys/net/if.c#n950 =
=20

If I read the code correctly, the clone created interface is made =
visible via `if_link_ifnet(ifp);` , and at that time the
`ifp->if_afdata[AF_INET6]` is NULL and is not initialized yet by =
`if_attachdomain1()` which will call `in6_domifattach()`
to allocate the required data.

So I guess there is a race condition. I bet this can be repeated easily.

I have not tested this yet, and not sure if it is the right fix, but you =
can give it a try.

I'm =
not quite sure, but it seems the `ifp` is not fully constructed. =
See https://cgit.freebsd.org/src/tree/sys/net/if.c#n950 

If I read the code correctly, the =
clone created interface is made visible via `if_link_ifnet(ifp);` , and =
at that time the
`ifp->if_afdata[AF_INET6]` is NULL and is =
not initialized yet by `if_attachdomain1()` which will call =
`in6_domifattach()`
to allocate the required =
data.

So I guess there is a race =
condition. I bet this can be repeated easily.

I have not tested this yet, and not sure if it is =
the right fix, but you can give it a try.

    if_vxlan(4): Add checking for loops and nesting of tunnels

    User misconfiguration, either tunnel loops, or a large number of
    different nested tunnels, can overflow the kernel stack. Prevent that
    by using if_tunnel_check_nesting().

    if_vxlan(4): Add checking for loops and nesting of tunnels

    User misconfiguration, either tunnel loops, or a large number of
    different nested tunnels, can overflow the kernel stack. Prevent that
    by using if_tunnel_check_nesting().

--- Comment #5 from Sergey  ---
(In reply to Marek Zarychta from comment #4)
I have a master gateway that I have updated=20
FreeBSD localhost 13.2-RELEASE-p4 FreeBSD 13.2-RELEASE-p4 GENERIC i386
up to
FreeBSD localhost 14.0-RELEASE-p6 FreeBSD 14.0-RELEASE-p6 GENERIC amd64=20

After that, I encountered unstable operation of the static arp table, which=
 is
actively used there.

It seems that it is too early to upgrade to a 64-bit system.

Yes I think it was running netif restart wlan0 in loops.

I'll do; I haven't seen the error happening since on other test
machines, so not sure about repeatability.

I am also not entirely sure this is not a ping6 ff02::1%wlan0 while
the ifp was destroyed by netif restart at the same time the packet was
still on the way out?

If it was during create, the wlan(4) interface would not be associated
and UP at that point of if_attach_internal() and
`ifconfig inet6 -ifdisabled` would not have been run to be able to send
that packet in first place?

Othwerwise the packet would have had to "survive" the clone destroy and
clone create cycle somewhere ...?
