[PATCH] [RFC] wireless: move obsolete drivers to staging

[PATCH] [RFC] wireless: move obsolete drivers to staging

[Arnd Bergmann]

From: Arnd Bergmann <arnd@arndb.de>

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.

Stuff in drivers/staging/ is to get code _into_ the main portion of the
kernel tree, not out.  If these aren't being used, let's just drop them
entirely.

What is the need to have them move to staging, only to have me delete
them in the next release after that (or after that?)  Why delay and why
not just remove them now?

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
linux-wireless@vger.kernel.org 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.

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?

FWIW in Ethernet we do what Greg says. Delete it, if someone complains
we revert back in. The revert did actually happen once, it was pretty
painless (Greg even took it into stable tree, IIRC).

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).

I can do it, I've already done most of the work for moving the
drivers, so I just need to split up my existing patch and leave out
the bits that get added to drivers/staging.

I'll also send Greg a patch to remove rtl8192u now that we know
that this has been broken for 7 years. Similarly, I'd include
another patch to remove PCMCIA support for libertas, as that
would otherwise be the only remaining 16-bit PCMCIA wlan card,
and I could find no indication of this one ever being popular,
unlike the USB/SDIO/SPI variants of the same device or the
other PCMCIA drivers.

This would leave only a handful of wext implementations in the
tree: ipw2x00, ps3-gelic-wireless, staging/rtl8712, staging/rtl8192e
and staging/ks7010. Since ipw2x00 is apparently still supported
in theory and was rather popular on Pentium-M based systems 20
years ago, this may still need to be converted to cfg80211
before you can remove support for wext style drivers altogether.
ps3-gelic-wireless and rtl8712 are also still maintained but have
a much smaller user base I assume.

Actually I would prefer to remove ipw2x00 and ps3-gelic-wireless as
well. I have not seen any evidence that there would be users for those
drivers. If we find out that there really are users I can easily add the
drivers back. The faster we get rid of wext the better, it really needs
to go away.

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 :-)

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

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].

I looked at that yesterday, and sadly I _think_ it's not even possible,
there are some corner cases in it like "no WPA2" that don't seem to be
fully covered in cfg80211/nl80211, at least not with the APIs today and
with current versions of wpa_supplicant.

It might still be doable because things like
WPA_DRIVER_CAPA_KEY_MGMT_WPA2_PSK don't really seem to be used much in
wpa_supplicant, but we'd have to carefully test that I guess.

Also, it depends on the PS3 firmware version whether or not that's
supported.

Then again, arguably wifi without WPA2 is pretty much useless these
days?

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?

Hi Arnd,

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.

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, 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.

OpenWRT is clearly not a good metric for laptops, but it's a good
indicator for embedded systems, in particular those with wireless
access points, and it does enable a lot of them
(atheros, broadcom, intel, marvell, ralink, realtek, mt76, wlcore,
rsi ...) depending on the platform.

I can also see that it used to enable airo, p54, hermes, adm8211,
zd1211, ipw2x00 and libertas but stopped this a year ago, see
https://github.com/openwrt/openwrt/commit/a06e023b4e12

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.

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.

Bye Philipp

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.

I do not know about the the others, but rtl8712 is still in use according to the 
flow of questions I see on a GitHub repo that I maintain.

There has been some recent effort to convert rtl8192e to use cfg/nl/mac80211. 
That one is problematic as it has the same PCI_ID as RTL8192SE, but the drivers 
differ. Note the special code in the probe routine of 
drivers/net/wireless/realtek/rtlwifi/rtl8192se to detect if the wrong one has 
triggered the routine. That code should also be in the probe routine for 
RTL8192E with the test negated. I have both devices, but it has been a long time 
since I actually used either of them. I also have an rtl8712 device, thus I 
should be available for testing.

Hi,

__rtl8192e__
this hardware is available on ebay 13 times.
ping statistics:
1191 packets transmitted, 1191 received, 0% packet loss, time 1192169ms
rtt min/avg/max/mdev = 0.633/2.184/74.792/3.157 ms
maximum download 12,5 MByte/s

__rtl8712__
stick packard bell AW-NU120
ping statistics:
678 packets transmitted, 652 received, 3.83481% packet loss, time 678287ms
rtt min/avg/max/mdev = 0.943/4.835/231.435/17.900 ms
maximum download 12,5 MByte/s

I would like to remove the private functions as the "wireless tools" 
package is deprecated. The following functions are available:
kernel@matrix-ESPRIMO-P710:~/Documents/git/kernels/staging$ iwpriv wlan0
wlan0     Available private ioctls :
           read32           (8BE0) : set   1 int   & get   0
           write32          (8BE1) : set   1 int   & get   0
           driver_ext       (8BE2) : set   0       & get   0
           mp_ioctl         (8BE3) : set   0       & get   0
           apinfo           (8BE4) : set   1 int   & get   0
           setpid           (8BE5) : set   1 int   & get   0
           wps_start        (8BE6) : set   1 int   & get   0
           chplan           (8BE7) : set   1 int   & get   0

What do you think about this?

Thanks

Bye Philipp

Larry is the maintainer for rtl8712, so he'd be the one to answer
this. Out of the four drivers that are left using wext after
my current draft removal series, only ks7010 and rtl8712
use the private handlers, so in theory we could remove
the CONFIG_WEXT_PRIV first, but I'm not sure that makes
any difference if the plan is to convert all wext drivers
to cfg80211 anyway.
