From: Arnd Bergmann <[email protected]>
While looking at the old drivers using the obsolete .ndo_do_ioctl()
callback, I found a number of network drivers that are especially
obsolete, in particular for 802.11b (11Mbit/s) or even older wireless
networks, using non-busmaster ISA/PCMCIA style bus interfaces, and using
the legacy wireless extension ioctls rather than the netlink interfaces
that were meant to replace them in 2007. All of these drivers are
obsolete or orphaned.
We had previously discussed this topic, but nobody ever moved the
files, so I now went through the list to my best knowledge. These
are the drivers that I would classify as "probably unused" by now:
- Atmel at76c502/at76c504/at76c506 is a PIO-only (PCMCIA, mini-PCI
and Cardbus) 802.11b driver with incomplete CFG80211 support.
The related at76c50x USB driver uses MAC80211 and remains.
- Cisco Aironet is an 802.11b PCMCIA and mini-PCI with limited support
for Cardbus DMA and for CFG80211.
- HostAP is an ISA/PCMCIA style 802.11b driver supporting only
wireless extensions, and some custom ioctls (already removed).
Some devices include a legacy PCI bridge but no DMA.
- Aviator/Raytheon is an early PCMCIA driver, apparently predating
802.11b and only supporting wireless extensions.
- Planet WL3501 is another PCMCIA driver for pre-802.11b interfaces
(2Mbit/s) with incomplete CFG80211 support
- Zydas zd1201 is a USB 802.11b driver with limited support for
CFG80211.
- Orinoco is a PIO-only ISA/PCMCIA 802.11b device with extra bus
interface connections for PCI/Cardbus/mini-PCI and a few
pre-2002 Apple PowerMac variants. It supports both
wireless extensions and CFG80211, but I could not tell if
it requires using both.
- Wireless RNDIS USB is a new-style CFG80211 driver for 802.11b
and 802.11g USB hardware from around 2004 to 2006. This makes it
more modern than any of the others, but Kalle already classified
it as "legacy" in commit 298e50ad8eb8f ("wifi: move raycs, wl3501
and rndis_wlan to legacy directory"), so it stays with ray_cs and
wl3501_cs.
There are a few other drivers that are similar to these but that are
more likely to still be needed, and are not moved here:
- Intel ipw2x00 is a PCI bus-master device for 802.11a/b/g that was
popular in "Centrino" branded laptops from 2003 to 2005, but it
still requires wireless extensions.
- Marvell Libertas is an 802.11a/b/g device with a number of bus
interfaces (USB, SDIO, SPI, PCMCIA) and incomplete CFG80211
support. This one was used in the OLPC XO laptop and some other
embedded devices that are still supported.
- Some broadcom b43xx devices use the SSB bus that can be abstracted
through PCMCIA. All of them use CFG80211.
- The Sony Playstation 3 "gelic" ethernet driver contains a bridge
and an 802.11b/g client chip that is controlled through a hypervisor
interface from the OS, and it uses wireless extensions in the kernel
driver.

I'm mainly taking educated guesses about which drivers are actually
obsolete. Let me know if I got any of them wrong, or if any others
should be included here.
I did not move the staging drivers for ks7010, rtl8192e, rtl8192u,
rtl8712, rtl8723bs, vt6656 or wlan-ng into driver/staging/wireless,
as they are already directly under drivers/staging, but that could
be another patch if we want to keep them all in one place.

+TODO (Oct. 2023)
+
+These 802.11(b) wireless drivers are likely all unused and can be removed
+in the near future, unless we find a reason to keep them.
+
+All except the rndis_wlan driver still rely on the deprecated wireless
+extension ioctl interface, which in modern drivers is only provided
+as an emulation layer on top of the cfg80211 interface.
+
+Ideally, any drivers we want to keep around should be converted to no
+longer require iw_handler_def.

We (the wireless folks) have been talking about dropping legacy drivers
on and off for several years now. The problem is that we don't know
which of them work and which not, for example IIRC someone reported
recently that wl3501 still works.
Personally I would be extremly happy to remove all the ancient drivers
as that reduces the amount of code for us to maintain but is that the
right thing to do for the users? I don't have an answer to that,
comments very welcome.
I have been also wondering if I should add warnings like this to every
ancient driver to see if there are any users left:
"wl3501 wireless driver will be removed in 2024. If the driver still
works and you are using it send a report NOW to
[email protected] to avoid the removal."
But with the long release cycles the kernel and distros have I doubt
waiting for a year is enough, it should be more like three years.

No matter what the time frame is, it's never going to line up with all
distros, or catch everyone properly.
I recommend, just delete all the ones you feel are not being used, in a
patch that removes them one-by-one, so that it is trivial to revert if
someone shows up and says "hey, my device stopped working!" a few years
in the future.

I had a look at what openwrt enables, to see if any of the drivers
in my RFC patch are actually enabled, if anything supports legacy
embedded devices with these it would be openwrt. The good news here
is that openwrt intentionally leaves WEXT disabled, and none of them
are still in use.
I also did the same thing for the kernel defconfig files, which
has a few hits:

My interpretation here is that these defconfigs just enabled
all drivers that were relevant at the time when the boards
were new. The loongarch defconfig is a bit of an outlier,
as this is a fairly new platform.
Debian on the other just enables every driver, so there
is no good way to know what they actually use.

Yeah, that's true.

I'm starting to lean towards this as well. We have talked about this for
so long now but no practical solution ever found so maybe just bite the
bullet finally. What do others think?

Yeah, as you point out, we can't go by distro kernel configs as they
obviously error on the side of "build everything!". But your openwrt
info is good, thanks for that, that's a huge hint that no one uses those
drivers anymore.

I don't think openwrt is a good metric in this case. These drivers are
for 20+ years old hardware, most likely running on really old x86
laptops. So the chances of them running openwrt on those laptops is low
and I would expect them to run more traditional distros like debian or
ubuntu. But of course this is just guessing.

Nice, thanks so much for testing.
I see the two bugs were introduced in 2016 by commit 1761a85c3bed3
("staging: rtl8192u: Remove create_workqueue()") and in 2021 by
commit 061e390b7c87f ("staging: rtl8192u: ieee80211_softmac: Move a
large data struct onto the heap"), so it's been broken for a while.
I also checked rtl8192e for the same bugs, but that driver
managed to avoid this even though it had the same code
originally.
Regarding the firmware files, I found:
- rtl8192e, rtl7812 and rtl8723bs are all in the linux-firmware
package, unlike rtl8192u
- atmel firmware is not in upstream linux-firmware, but Debian
has an atmel-firmware package for it
- I could not find a Debian package for ks7010sd.rom
- vt6656/vntwusb.fw is in firmware-misc-nonfree
- orinoco has multiple firmware files, but only agere_sta_fw.bin
and agere_ap_fw.bin are in Debian and linux-firmware.

This one never made it to lore... I think we wouldn't have merged it
without a lore review these days. (There was a lot of moaning and
complaining at the time).

:/ No way would I have seen this in review. Smatch is supposed to find
some of these "sleeping in invalid context" warnings but the sleeping in
IRQ stuff doesn't work and hasn't been released.

Thanks, good to know that you have had positive experiences with this
approach. As I didn't hear any concerns from anyone so I'm convinced we
should do this. I'm sure it will make my life a lot easier :)
Is anyone willing to submit patches? Use wireless-next as the baseline
for patches and one driver per commit, please. That way it's easy to
revert later, if needed (hopefully not).

If you didn't update the firmware, you could keep on using Linux.
And people may have found a vulnerability in more recent firmware
versions that allows them to run custom software.
I don't know, it's been +10 years ago I touched a PS3 ;-)

Yeah, fair.

I never had one :-)
But seriously - is it worth to try to keep a wireless driver for it if
we don't even know anyone using a PS3 at all?
But maybe we'll find someone :-)

Hi Arnd,
please allow me to do this.
I had a separate mail with Greg this morning...
https://lore.kernel.org/linux-staging/2023101244-unaudited-sadly-d9d6@gregkh/T/#t
Waiting for your confirmation who is sending the patch for removal.
Thanks

This was only for CF cards of which there were a couple; I still have
cards but don't have a machine with CF anymore. USB/SDIO/SPI (as you
point out) have much higher usage.
ACK from me (if my historical libertas involvement counts for anything)
on removing Libertas CF support.

There is still a considerable user base for the PS3, so we
must keep the ps3-gelic-wireless driver.

Hi Arnd,
we should take into account how good the wlan connection is.
This of course leads to tests on real hardware. I do have a vt6655.
Please have a look at the test results below. In a nutshell it is a very
bumpy connection you get with vt6655. You can have issues to connect on
every channel and data is coming in waves. So sometimes you will almost
not notice you have a wlan connection and then it takes very long to
load the next site. Ping times up to 80 seconds. Packet losses up to
40%. So I assume all users have gone away from this module as it is not
comfortable.
Do you think this helps you?
I do have two vt6656 hardware as well. Are you interested in tests?
I can do a patch to remove vt6655. Do you think it makes sense?
Thanks for your support.

Hi Philipp,
My vague feeling is that bad performance on its own is not
enough justification to remove the driver without some other
reason. From what I can tell in the logs, Malcolm Priestley
made good progress on cleaning up theses driver, converting it
to mac80211 and sending improvements until 2020.
At the moment, I'd suggest focusing on the drivers that
still use wext (git grep -w iw_handler_def drivers), if we
can show that rtl8192e, rtl8712 or ks7010 have been broken
for a while, removing those would help with removing wext
altogether.

Do you know if anyone has tried changing this driver over to the
cfg80211 interface from the wireless extensions? With the
series I have prepared now, it is the only driver outside of
drivers/staging that still uses wext and stops us from removing
that altogether.
[side note: it appears that the PS3 I have is the only model
without wireless networking, as I bought cheapest Asian 20GB version
back in early 2007. It still has the original firmware on it
and should run Linux, but I haven't tried it since at least
2009].

This is a good point. It doesn't matter if the clients work if there are
no Access Points to connect to. And if you do have an old one you can
connect to, it will be an insecure connection. Wardriving, anyone?
