LinuxLists.cc - [PATCH 01/10] appletalk: remove localtalk and ppp support

Subject: [PATCH 01/10] appletalk: remove localtalk and ppp support

From: Arnd Bergmann <[email protected]>

The last localtalk driver is gone now, and ppp support was never fully
merged, so clean up the appletalk code by removing the obvious dead
code paths.

Notably, this removes one of the two callers of the old .ndo_do_ioctl()
callback that was abused for getting device addresses and is now
only used in the ieee802154 subsystem, which still uses the same trick.

The include/uapi/linux/if_ltalk.h header might still be required
for building userspace programs, but I made sure that debian code
search and the netatalk upstream have no references it it, so it
should be fine to remove.

Subject: [PATCH 05/10] staging: rtl8192: remove unused legacy ioctl handlers

From: Arnd Bergmann <[email protected]>

The .ndo_do_ioctl functions are never called, and can just be removed,
especially since this is a staging driver.

Subject: [PATCH 06/10] staging: rtl8712: remove unused legacy ioctl handlers

[permalink] [raw]

Subject: [PATCH 07/10] staging: rtl8723bs: remove dead code

From: Arnd Bergmann <[email protected]>

The .ndo_do_ioctl functions are never called, so the three implementation here
is useless but only works as a way to identify the device in the notifiers,
which can really be removed as well.

Looking through the exported functions, I found a bunch more that have
no callers, so just drop all of those.

Subject: [PATCH 10/10] net: remove ndo_do_ioctl handler

All of the references to the callback pointer are gone, so remove the
pointer itself before we grow new references to it.

Does it really need it to be a kernel protocol stack?
What about doing it in userspace or with BPF?

Looks like it depends on the ipddp driver removal.
Could you repost once that one is merged (~tomorrow)?

Yes I too think it is good to remove ndo_do_ioctl, I designed the TashTalk driver to be a drop-in replacement for COPS mostly for compatibility with netatalk 2.2. My plan was to propose it like this (so nothing else needed to be changed) and the propose some patches in the kernel part and userspace part (netatalk).

This was my initial thought, at least for the moment, mostly to keep netatalk happy and make sure I don’t break other stuff that makes assumptions on how the address probing worked. There are other bits I would like to improve, for example tcpdump (which parses correctly appetalk packets!) is broken in the current implementation.

This is sorta the “second step” I was planning, I think the logic for probing could be redesigned and simplified (it also does not work 100% correctly), and it could be a good chance to improve the interface with netatalk too.

We had some discussion too if to just make the lt an userspace stack, I personally like how it is currently implemented because existing code can run basically without modification.

I would propose at this stage to change the TashTalk driver to remove ndo_do_ioctl and to use a custom callback, if this ok.

Many thanks,

Subject: [PATCH v2] appletalk: make localtalk and ppp support conditional

From: Arnd Bergmann <[email protected]>

The last localtalk driver is gone now, and ppp support was never fully
merged, but the code to support them for phase1 networking still calls
the deprecated .ndo_do_ioctl() helper.

In order to better isolate the localtalk and ppp portions of appletalk,
guard all of the corresponding code with CONFIG_DEV_APPLETALK checks,
including a preprocessor conditional that guards the internal ioctl calls.

This is currently all dead code and will now be left out of the
module since this Kconfig symbol is always undefined, but there are
plans to add a new driver for localtalk again in the future. When
that happens, the logic can be cleaned up to work properly without
the need for the ioctl.

Link: https://lore.kernel.org/lkml/[email protected]/
Signed-off-by: Arnd Bergmann <[email protected]>

v2: don't actually remove the code, just make it conditional since we
are likely to need it again.

Ok, I've adapted my patch now to not actually drop the
localtalk code for now, and sent that out, I hope that works
for you. Even if we go with the v1 patch that removes it all,
you could just as well start with a revert of my patch when
you add your driver, so in the end it shouldn't make much
of a difference.

It looks like you still need a custom userspace tool to set up
the uart for your new driver, so my feeling would be that having a
userspace bridge to implement the localtalk/uart to ethertalk/tap
driver would actually be nicer for both usability and maintenance.

It's not something we need to decide now though, and is up to
you in the end.

Thank you very much! I will try to make my patch ready to be submitted soon, and I will add the proper reverts if needed.
