Intel wireless driver crashes on connection on WiFi Link 5300

[jjido]

After connecting to my network, the wifi driver crashes. I tested Alpha 4 and the latest nightly (hrev47061).

It is a WPA protected open network. The wireless looks to work in other respects.

The card is an Intel wifi link 5300.

I was able to use the network with FreeBSD 10, so it may just be an issue of updating the iwn driver.

The crash does not occur with the latest driver compiled from the FreeBSD source.

I will attach a patch.

[jjido]

Patched iwn source (using FreeBSD sources)

[korli]

Please provide a git-formatted patch, with information on the FreeBSD tag used (when possible avoid HEAD).

[jjido]

My patch is apparently based on this code:

​http://sources.freebsd.org/RELENG_8/src/sys/dev/iwn/

Mmh. I don't know why I selected that version ???

Which one would be more suitable, I will happily test it with my hardware.

[korli]

Suitable would be version 10.0.0 but the wireless FreeBSD code has too much changed and a simple update doesn't work (or even build) as is. In any case: ​http://svnweb.freebsd.org/base/release/10.0.0/sys/dev/iwn/

[jjido]

The 9.3.0 has been updated 4 weeks ago, as opposed to 6 months for the 10.0.0 branch. I will try getting either to compile and test it on my laptop.

​http://svnweb.freebsd.org/base/release/9.3.0/sys/dev/iwn/

[korli]

We already use the 9.3 release.

[jjido]

Ok, I can see that the code at head is from 9.3 (which fails) and 10.0.0 doe snot compile.

The first error is: /boot/home/dev/haiku/src/add-ons/kernel/drivers/network/wlan/iprowifi4965/dev/iwn/if_iwn.c: In function `iwn_rate_to_plcp': /boot/home/dev/haiku/src/add-ons/kernel/drivers/network/wlan/iprowifi4965/dev/iwn/if_iwn.c:2301: warning: implicit declaration of function `ieee80211_legacy_rate_lookup'

I will see if I can find the missing symbols and add them to src/libs/compat/freebsd_wlan/net80211/ieee80211_var.h

[korli]

It's also very possible that the FreeBSD compat layer isn't up to date with FreeBSD network layer changes. Could you check with FreeBSD 9.3 that your wireless connection works as expected? Maybe related: ​http://bugs.dragonflybsd.org/issues/2675

[jjido]

I managed to compile the FreeBSD 10.0.0 driver, and tested it successfully. Works fine for me.

Attaching patch.

[jjido]

FreeBSD 10.0.0 based patch

[korli]

This patch cannot unfortunately be applied as is. I'll try to come with a release update, but network drivers are sensitive subject, difficult to test extensively.

The 4965 driver has been synced with FreeBSD 11 now.
