Hi,
I hit a problem when attempting to upgrade to kernel 3.17.2 on a
particular server.
Some time between 3.13 and 3.17, the bonding driver has stopped
accepting ppp devices, instead throwing an error that the MAC address
cannot be changed.
(And does not allow this to be forced)
I suspect it's unlikely.. but has anyone here encountered this issue
and found a solution?
Alternatively.. do you know where the right place to file bug report
about this would be? It's been a while since I've filed anything
against the linux kernel itself.
Cheers,
Toby

I have two upstream PPPoEs to different ISPs.
I don't bond them, but I have policy routing magick to send replies out
the correct link (without bothering with BGP and an AS):

No idea if that's a usable plan B for your setup.

If it's a stock kernel, complain to your distro.
If you're compiling it yourself, have you double-checked that you
haven't accidentally =n'd something you need for bonds to accept pppN?

It's a mainline kernel I was trying.. Doesn't look like there's
anything new or changed in the config around either the network
bonding driver, or the ppp network driver.
What is particularly strange, is that between 3.13 and 3.17, this
commit was added:
bonding: permit enslaving interfaces without set_mac support
https://github.com/torvalds/linux/commit/f54424412b6b2f64cae4d7c39d981ca14c…
ie. That seems to suggest what I was doing *wouldn't* work previously,
but would in 3.17, yet my experience is the opposite... o.O
However it looks like the way they handle/reach the error is
different, and the commit gives me some hints that it *should* work..
perhaps by ensuring that the bonding driver is set to balancing before
adding any slaves. (Maybe the Ubuntu/Debian network start-up is adding
slaves before setting mode?)

I don't think it'll work in my case, as incoming data streams are
split up between the links (so I get an aggregated amount of
bandwidth, even on single TCP streams on the downlink)

In regard to the commit you mentioned later in the thread, git shows the
author as:
Author: Veaceslav Falico <vfalico(a)gmail.com>
So perhaps contacting him might be useful if you can demonstrate that
reverting that commit fixes the regression.
Linus takes a dim view of people breaking compatability so it may also be
worth asking on LKML.
Good luck!

I never did manage to get things running on 3.17.4 (latest stable) and
couldn't see anything promising committed to latest release candidate,
so have submitted a bug report:
https://bugzilla.kernel.org/show_bug.cgi?id=89161
Have not as yet tried reverting just that commit as there's always too
much other stuff to be doing in the day :(

Have you tried the teaming driver? They seem to be phasing out the
bonding driver in favour of team. But I've never seen team in action, so
don't know how it compares.

New subject: Kernel 3.17 (and later) no longer allows bonding ppp devices
Just rebooting a thread a year later..
Thought I'd mention that
a) the teaming driver doesn't support bonding ppp devices
b) the linux kernel bonding driver still hasn't corrected the regression I
reported a year ago.
c) I patched the kernel myself, and thus have a working modern kernel again.
Patch is attached to the bug report below.
d) Linux netdev mailing list pretty much ignored my attempts to get this
sorted out, so I gave up, and will just quietly keep patching my own
kernels.
Figured I'd mention this in case anyone else comes across this thread while
searching for a solution.

Disappointed to hear that.. :-(
