  [Impact]

   * bcmwl does not compile on new kernels (or HWE kernels)
   * bcmwl suffers from null reference bug 

  [Test Case]

   * public PPA provided to community and feedback
   * based on patch available to other distros
   * comment #42

  [Regression Potential]

   * for changes on kernel support it may not compile (tested with 3.2, 3.13, 
3.18 and 4.2)
   * for the null reference change -> proved to fix problem for community based 
on feedback

  [Other Info]

  Original bug description:

  The bcmwl package as of now misses one patch for a bug that occurs
  with BCM43142 and possibly other broadcom chipsets that will look like
  random disconnects, poor wifi signal and kernel warnings, See also
  #1379524.

  Adding the patch is a fairly simple process:

  * put the patch file in /usr/src/bcmwl-6.30.223.248+bdcom/patches
  * add the following line to  /usr/src/bcmwl-6.30.223.248+bdcom/dkms.conf
  PATCH[7]="0014-null-pointer-crash.patch"
  * run: /usr/lib/dkms/common.postinst bcmwl 6.30.223.248+bdcom 
/usr/share/bcmwl x86_64 $(uname -r)

  This has fixed the issue for me. Edit: I just wanted to add that I did
  not write the patch; I merely downloaded it from a paste that was
  linked from the respective AUR package.

Newer releases will have this fix though.

  The bcmwl package as of now misses one patch for a bug that occurs
  with BCM43142 and possibly other broadcom chipsets that will look like

  #1379524.

  Adding the patch is a fairly simple process:

  * run: /usr/lib/dkms/common.postinst bcmwl 6.30.223.248+bdcom 
/usr/share/bcmwl x86_64 $(uname -r)

  This has fixed the issue for me. Edit: I just wanted to add that I did
  not write the patch; I merely downloaded it from a paste that was
  linked from the respective AUR package.

[Martin Pitt]

The version of bcmwl in the proposed pocket of Precise that was
purported to fix this bug report has been removed because the bugs that
were to be fixed by the upload were not verified in a timely (105 days)
fashion.

Hi Karen,

The location of the patch directory is as outlined above on 16.04. Please
double-check that you have installed the correct version of the package (this 
should
be 6.30.223.248+bdcom). Otherwise, please post the contents of your /usr/src 
directory to progress
this further.

I found the patch, but I'm using Ubuntu 16.04 LTS and there is no such
directory as specified below (the place where I'm supposed to put this
patch).  What to do?

[Kernel-packages] [Bug 1415880] Re: 14e4:4365 bcmwl-kernel source: fix for null pointer crash

[Karen Corrick]

This is not a simple process for new ubuntu users.  Where do I get the patch 
file?  Where is it?  Every time I click on "choose" by package, I get a 
clickable item, click on it, but then nothing happens.  How do I do the 
following???
Adding the patch is a fairly simple process:
* put the patch file in /usr/src/bcmwl-6.30.223.248+bdcom/patches

  Original bug description:

  The bcmwl package as of now misses one patch for a bug that occurs
  with BCM43142 and possibly other broadcom chipsets that will look like
  random disconnects, poor wifi signal and kernel warnings, See also
  #1379524.

  Adding the patch is a fairly simple process:

  * put the patch file in /usr/src/bcmwl-6.30.223.248+bdcom/patches
  * add the following line to  /usr/src/bcmwl-6.30.223.248+bdcom/dkms.conf

  * run: /usr/lib/dkms/common.postinst bcmwl 6.30.223.248+bdcom 
/usr/share/bcmwl x86_64 $(uname -r)

  This has fixed the issue for me. Edit: I just wanted to add that I did
  not write the patch; I merely downloaded it from a paste that was
  linked from the respective AUR package.

[Kernel-packages] [Bug 1415880] Re: 14e4:4365 bcmwl-kernel source: fix for null pointer crash

[Dmitry Mazur]

Hi, don't know where to post this (and my English is not so good,
sorry), but: i have the same problems with my bcm43142 (HP G4 250
laptop) + (4.4.0-24-generic #43-Ubuntu 16.04 64'bit' GNU/Linux) - it
drops connections per "any random time". Today (after many days of
wifipain) I've seem that ping drop so many packages, BUT not for the
first time - ONLY when u start ping anywhere for the second time after
`modprobe or .. wifi goes on?` ! So i have decided to check if terminal
will always ping ( * my router ip, cause don't be banned by anybody, of
couse) and what i've seen: NO DROPPING while pinging. at all. (also
packets AND wifi connection i mean + wifi signal meters "don't jump").
(64 bytes from 192.168.10.1: icmp_seq=6338 ttl=64 time=0.628 ms). but.
Before this i disabled ipv6 and don't change it back.. Tomorrow will
check with ipv6 and other options.. I know this is not a cure, but it's
working for me. What do next if i can help?

I believe this bug was fixed i Trusty with Bug #1518956

There isn't currently a bcmwl package in trusty-proposed.

http://askubuntu.com/questions/620494/ubuntu-15-04-suspend-doesnt-run-pm-suspend
 (needed for 15.04 or higher)
- in /etc/pm/sleep.d create file with some name (for example 01_wifi_wl) with

One of my clients has a laptop with the BCM43142 running Ubuntu 14.04
(kernel 3.16) with this patch applied. It unfortunately does not solve
the issue. Random disconnects after some time continue.

[Kernel-packages] [Bug 1415880] Re: 14e4:4365 bcmwl-kernel source: fix for null pointer crash

[Arun kumar]

I've this version of the driver 
(https://launchpad.net/ubuntu/wily/amd64/bcmwl-kernel-source/6.30.223.248+bdcom-0ubuntu7)
 installed on dell inspiron 5520 which has same BCM43142 WIFI adapter. I'm 
having the same problem with the latest version of the package installed on 
ubuntun 15.10. 
Followed recommendations to fix wifi adapter to a fixed Access Point but still 
it is roaming and gets disconnected after an interval of time.
Any updates on this ?

  Original bug description:

  The bcmwl package as of now misses one patch for a bug that occurs
  with BCM43142 and possibly other broadcom chipsets that will look like
  random disconnects, poor wifi signal and kernel warnings, See also
  #1379524.

  Adding the patch is a fairly simple process:

  * put the patch file in /usr/src/bcmwl-6.30.223.248+bdcom/patches
  * add the following line to  /usr/src/bcmwl-6.30.223.248+bdcom/dkms.conf
  PATCH[7]="0014-null-pointer-crash.patch"
  * run: /usr/lib/dkms/common.postinst bcmwl 6.30.223.248+bdcom 
/usr/share/bcmwl x86_64 $(uname -r)

  This has fixed the issue for me. Edit: I just wanted to add that I did
  not write the patch; I merely downloaded it from a paste that was
  linked from the respective AUR package.

  Original bug description:

  The bcmwl package as of now misses one patch for a bug that occurs
  with BCM43142 and possibly other broadcom chipsets that will look like
  random disconnects, poor wifi signal and kernel warnings, See also
  #1379524.

  Adding the patch is a fairly simple process:

  * put the patch file in /usr/src/bcmwl-6.30.223.248+bdcom/patches
  * add the following line to  /usr/src/bcmwl-6.30.223.248+bdcom/dkms.conf
  PATCH[7]="0014-null-pointer-crash.patch"
  * run: /usr/lib/dkms/common.postinst bcmwl 6.30.223.248+bdcom 
/usr/share/bcmwl x86_64 $(uname -r)

  This has fixed the issue for me. Edit: I just wanted to add that I did
  not write the patch; I merely downloaded it from a paste that was
  linked from the respective AUR package.

[monochromec]

In case you are running on problems with the NetworkManager (version
1.0.4-ubuntu5) after the official upgrade to Wily (messages "[platform
/nm-linux-platform.c:2782] do_change_link(): platform-linux: do-change-
link: failure changing link 4: No such device (31)" or similar) after
wakeup from a suspend, simply restart the NetworkManager with a suitable
script in /lib/systemd/system-sleep in order to get autoconnect working
again.

[Kernel-packages] [Bug 1415880] Re: 14e4:4365 bcmwl-kernel source: fix for null pointer crash

[ser]

Just a note to confirm that wily's bcmwl-kernel-source_6.30.223.248
+bdcom-0ubuntu4.1_amd64.deb works a treat.  I've been running it for a
few days now, and I've gotten to the point where I trust it enough to
close the lid even when walking to a nearby conference room a couple of
seconds away.  I haven't had a single panic since installing the
package.

Absolutely beautiful.

[Kernel-packages] [Bug 1415880] Re: 14e4:4365 bcmwl-kernel source: fix for null pointer crash

[Rafael David Tinoco]

Daniel,

SRUs are done from Development versions to more stable ones. This way we
can guarantee that LTS versions are good (even more than just relying on
verification process). It might take awhile for Trusty and Vivid to get
sponsored.

Brian,

Thank you very much for the feedback.

  with BCM43142 and possibly other broadcom chipsets that will look like
  random disconnects, poor wifi signal and kernel warnings, See also
  #1379524.

  Adding the patch is a fairly simple process:

  * put the patch file in /usr/src/bcmwl-6.30.223.248+bdcom/patches
  * add the following line to  /usr/src/bcmwl-6.30.223.248+bdcom/dkms.conf

  This has fixed the issue for me. Edit: I just wanted to add that I did
  not write the patch; I merely downloaded it from a paste that was
  linked from the respective AUR package.

[Kernel-packages] [Bug 1415880] Re: 14e4:4365 bcmwl-kernel source: fix for null pointer crash

[Brian Burch]

Just a personal update.

I've been using a manually patched version of the i386 driver for
several months, but I only use up to 0014-null-pointer-crash.patch. I
currently have the trusty 3.13.0.-63.103-lowlatency kernel on a dell
1558 and the BCM4315. I haven't seen another null pointer crash since I
applied the patch, but have suffered random loss of wifi
synchronisation, sometimes after a day or so, but other times every hour
or even less.

I didn't expect to see a difference, but I thought it was worth saying
that I successfully applied the just-released wily package bcmwl-kernel-
source_6.30.223.248+bdcom-0ubuntu4.1_i386.deb to my trusty system. The
build was clean (logged "using CFG80211 API") and the driver loads
without a problem.

I haven't been using it long enough to say whether it is better, but it
is definitely no worse!

[Kernel-packages] [Bug 1415880] Re: 14e4:4365 bcmwl-kernel source: fix for null pointer crash

[Martin Oemus]

For a while I stopped using suspend and it seemed promising, but today I
experienced problems directly after booting.

1)
I'm afraid the log I posted earlier was not very meaningful. I triggered the 
behaviour by closing the lid of my laptop because this was a way to safely 
reproduce the issues. This seems to be a physical problem of my laptop. 
Probably the wifi antenna gets shielded when the lid is closed. In Windows 7 
connection quality drops significantly and bandwidth goes down to 300 KB/s. In 
Linux the connection goes down completely (ping says Network is unreachable), 
produces the messages I posted earlier, including the call traces.
As annyoing as this is, it is probably nothing we can do anything about. The 
driver might not work as efficient as in Windows but that's it.

2) 

This only means that broadcom WL driver tried to warn kernel that it roamed 
from one AP to another and new BSS could not be found (meaning that the card 
could not get all its new BSS - peers, APs, etc).

My network consists only of one BSS (router), but I tried it anyway. I set the 
mac address of my router in the BSSID field in the networkmanager interface. 
This didn't change anything at all, I still got call traces, indicating, 
according to you, failed roaming attempts.

3) 
I attached the syslog from this morning. The problems start at 11:40:16 with 2 
call traces. At 11:40:57 wpa_supplicant gives CTRL-EVENT-ASSOC-REJECT messages. 
Google recommends blacklisting certain modules, but none of them are loaded on 
my system. Another call trace follows and networkmanager says it's 
disconnected. It goes on a bit and finally re-establishes the connection. This 
seems to be more or less stable for already two hours or so.


I really don't know what to make of this. I can't see a distinct pattern. I'm 
not dependent on Wifi, so it's not a big deal. 
Yet I'm still interested in solving this issue. My next step would be to test 
the whole thing without networkmanager and see how things are then because I 
think networkmanager really complicates debugging this. I wanted to explicitely 
set wpa_supplicant to use WPA2-CCMP only because in some setups I experienced 
connection problems when this wasn't explicitely set, but networkmanager 
doesn't offer me a way to do this.

This only means that broadcom WL driver tried to warn kernel that it
roamed from one AP to another and new BSS could not be found (meaning
that the card could not get all its new BSS - peers, APs, etc).

*** Try configuring the wireless adapter to use a SPECIFIC AP *** and
check your wifi env for interferences that might be stepping into
broadcom's driver decisions on whether to roam or not -> This does not
mean a fix for WL is not needed, it only means we would have to wait for
Broadcom to come up with a new driver.

Based on good feedback from Igor I'll suggest fixes for all Ubuntu
versions. Even if upstream BW driver still faces problems with adapters,
we still have to fix this bug's original problem.

I'll attach debdiffs for this bug soon.

Alberto,

I saw you pushed precise into latest version (right now in -proposed),
I'll check if it also needs the fix and provide debdiff. Let me know if
you have any other comments since you've been handling all bcmwl work
and you are more into it than I am.

Thank you

Rafael

  14e4:4365 bcmwl-kernel source: fix for null pointer crash

Status in Dell Sputnik:
  Confirmed
Status in bcmwl package in Ubuntu:
  In Progress

Bug description:
  [Impact]

   * bcmwl does not compile on new kernels (or HWE kernels)
   * bcmwl suffers from null reference bug 

  [Test Case]

   * public PPA provided to community and feedback
   * based on patch available to other distros
   * comment #42

  [Regression Potential]

   * for changes on kernel support it may not compile (tested with 3.2, 3.13, 
3.18 and 4.2)
   * for the null reference change -> proved to fix problem for community based 
on feedback

  [Other Info]

  Original bug description:

  The bcmwl package as of now misses one patch for a bug that occurs
  with BCM43142 and possibly other broadcom chipsets that will look like
  random disconnects, poor wifi signal and kernel warnings, See also
  #1379524.

  Adding the patch is a fairly simple process:

  * put the patch file in /usr/src/bcmwl-6.30.223.248+bdcom/patches
  * add the following line to  /usr/src/bcmwl-6.30.223.248+bdcom/dkms.conf
  PATCH[7]="0014-null-pointer-crash.patch"
  * run: /usr/lib/dkms/common.postinst bcmwl 6.30.223.248+bdcom 
/usr/share/bcmwl x86_64 $(uname -r)

  This has fixed the issue for me. Edit: I just wanted to add that I did
  not write the patch; I merely downloaded it from a paste that was
  linked from the respective AUR package.

[Kernel-packages] [Bug 1415880] Re: 14e4:4365 bcmwl-kernel source: fix for null pointer crash

[Rafael David Tinoco]

Thanks for the feedbacks so far. Resuming results :

*Martin* (BCM43142) - has the adapter working but from time to time it
shows the kernel back traces and start having erratic behaviour. 3.19
is still supported (unfortunately this driver is an external dkms driver
so we are working on a best effort basis here. I'm trying to understand
what is going on and maybe discuss with Broadcom. Thank you for the
kernel back trace, I will check bcmwl code and back trace and provide
feedback.

*Zethan* (BCM4352) - has the adapter working (is this correct ?) and
suspend started working (but card is not operational after suspension).
What about unloading and loading the kernel module right after
suspension, does it fix the issue ?

Please, try to unload these modules and then load wl module again (right
after first boot AND after suspension):

  # rmmod brcmsmac
  # rmmod ssb
  # rmmod bcma
  # rmmod wl

  # insmod wl

*Igor* (BCM???) - hasn't been able to reproduce the original problem
(this bug's description) and everything seems fine.

[Kernel-packages] [Bug 1415880] Re: 14e4:4365 bcmwl-kernel source: fix for null pointer crash

[Rafael David Tinoco]

BTW, I just found out in one of my notebooks I have a :

03:00.0 Network controller: Broadcom Corporation BCM4331 802.11a/b/g/n
(rev 02)

And, just to keep history, I was able to suspend/resume... right after
suspension I got a:

ERROR @wl_cfg80211_scan : WLC_SCAN error (-22)

But right after I was able to re-scan and re-connect to same AP (using
the PPA).

[Kernel-packages] [Bug 1415880] Re: 14e4:4365 bcmwl-kernel source: fix for null pointer crash

[Zethan S]

Rafael. So, my wireless card is bcm4352. When I first installed Ubuntu
15.04, if I suspended the machine by closing it, it would have an
unresponsive black screen and blinking caps key when I opened it again.

After I got the PPA you gave in post #43, the suspend issue was fixed -
it awoke from all kinds of suspend correctly. However, I am no longer
able to use bcm4352 to access the internet.

Hope that clears it up.

[Kernel-packages] [Bug 1415880] Re: 14e4:4365 bcmwl-kernel source: fix for null pointer crash

[Rafael David Tinoco]

Errr, not really.

Can you provide me a sosreport from your system (possibly before and
after that behaviour) ? My e-mail is ina...@ubuntu.com. You can share a
dropbox link or something like it though e-mail, or even here if that is
okay for you.

1)

If what you saying is correct (that this PPA caused that behaviour) than
I expect you to remove the package (apt-get remove --purge bcmwl-kernel-
source) and then remove the ppa (add-apt-repository -r
ppa:inaddy/lp1415880) and then install package from -updates repository
(sudo apt-get update  sudo apt-get install bcmwl-kernel-source).

Having installed the previous version you can run sosreport right after
you reboot your notebook (after suspend caused it to freeze). This way I
can check previous kern logs for something.

2)

Right after that I'd like you to install the PPA and the package again
(sudo add-apt-repository ppa:inaddy/lp1415880  sudo apt-get update 
sudo apt-get install bcmwl-kernel-source) and, right after suspend, run
sosreport again (this time, since the notebook does not freeze,  you
won't need a reboot after suspend).

Tks

-Rafael

[Kernel-packages] [Bug 1415880] Re: 14e4:4365 bcmwl-kernel source: fix for null pointer crash

[Martin Oemus]

@Rafael: thank you for your efforts to fix this issue.

1)
I need more information than this. The PPA I provided works with Trusty, Vivid 
and Wily with 3.13, 3.18 and 4.2 kernels.
-
# TRUSTY (fix for future lts-wily kernel)

Trusty needs a fix for 4.2 lts-wily future kernel:

bcmwl, 6.30.223.248+bdcom, 3.13.0-63-generic, x86_64: installed # trusty
bcmwl, 6.30.223.248+bdcom, 3.19.0-27-generic, x86_64: installed # vivid-lts
bcmwl, 6.30.223.248+bdcom, 4.2.0-4-generic, x86_64: installed # wily-lts 
(fixed)
-
I'm confused - I have Linux martin04 3.19.0-26-generic. Is this ok or not? I 
aquired this kernel by following this: 
https://wiki.ubuntu.com/Kernel/LTSEnablementStack

If my kernel is not supported I will try a different version.

2)
I'm afraid I was not really aware of the suspend problem which means that my 
problems can also be linked to the suspend feature which I use heavily. For 
this reason I never tested how things work with a freshly rebooted system. I'm 
doing this test right now and will get back to you with the results.

3)
I looked for a log and attached it. It starts with the device waking up from 
suspend mode at 12:30. Everything is fine for about 30 minutes. The problems 
start  at 12:57:09.  What is the right term for the crash that is happening? 
It certainly is no kernel panic and the system does not crash or freeze. But 
afterwards I have very long ping times (1000 ms) and sometimes connection 
loss. Sometimes it seemed to get better after disabling/enabling the wifi 
adapter but I couldn't yet determine any particular pattern.

Best regards
Martin

[Kernel-packages] [Bug 1415880] Re: 14e4:4365 bcmwl-kernel source: fix for null pointer crash

[Igor Tarasov]

Testing the package from the PPA on Kubuntu 14.04.3 64bit, kernel
3.19.0-27-generic.

Current status: uptime 23 hours, 12 successful suspend cycles. It was
happening for me not every time, but I've tried really hard to reproduce
(downloading via wi-fi while attempting to suspend and trying other
stuff) and was unable to reproduce kernel panic. Will be monitoring
further.

[Kernel-packages] [Bug 1415880] Re: 14e4:4365 bcmwl-kernel source: fix for null pointer crash

[Rafael David Tinoco]

So,

It looks like there are 2 or 3 bugs together in this case (maybe ?).

I probably solved just the bug where null pointer was being referenced
(based on a a Debian Bug already solved).



Martin,

I need more information than this. The PPA I provided works with Trusty,
Vivid and Wily with 3.13, 3.18 and 4.2 kernels. Can you test other
kernels and provide feedback. Also, about the crash you are facing, can
you attach the crash log ?

Zethan,

Are you using the same model (BCM43142) ?  How come it is fixed
(suspend) and the card does not work ? Please provide better feedback.

Igor,

Are you using the same model (BCM43142) ? Please keep me updated on
status!



Unfortunately to follow bcmwl development is not an easy task since they
only provide .tar.gz sources (without any kind of versioning system).
Hopefully with better feedback (logs ?) I might be able to track fixes
in between released versions.

Thank you

Rafael

I'm using Ubuntu 14.04.3 LTS with kernel 3.19.0-26-generic x86_64 with
BCM43142. Neither the patch that was posted in the first place nor your
PPA seem to completely fix the issues. I still experience random
crashes, very long ping times and connection losses.

[Kernel-packages] [Bug 1415880] Re: 14e4:4365 bcmwl-kernel source: fix for null pointer crash

[Rafael David Tinoco]

Okay, so after reading all the bug I have the following summary:


1. The current trusty repository bcmwl-kernel-source 
6.30.223.141+bdcom-0ubuntu2 is used on my wife's laptop. This system is not 
experiencing null pointer crashes OR Scan_results errors. This evidence 
strongly suggests both problems were introduced with 
6.30.223.248+bdcom-0ubuntu1.


We have a problem introduced in between:

bcmwl-kernel-source | 6.30.223.141+bdcom-0ubuntu2

and

bcmwl-kernel-source | 6.30.223.248+bdcom-0ubuntu0.1
bcmwl-kernel-source | 6.30.223.248+bdcom-0ubuntu2
bcmwl-kernel-source | 6.30.223.248+bdcom-0ubuntu4


2. On checking syslog carefully, the Scan_results errors are often associated 
with the system running slowly and [TTM] Out of kernel memory messages being 
logged.

https://bugs.launchpad.net/ubuntu/+source/bcmwl/+bug/1415880/comments/15

I'm now on vivid (via do-release-upgrade -d), The problem reappears
without the patch. I am now reapplying the patch and see if it works
out. On vivid, with the patch, I still get the warning, but the
connection doesn't drop (at least for now, fingers crossed).

this patch fixes kernel crashes with kernels =3.18 for me on BCM43228.
I'm currently using it on top of vivids bcmwl-kernel-source: 
6.30.223.248+bdcom-0ubuntu2 and the vivid 3.19.0 kernel


It looks like the patch fixes the out of memory problem.


-kernel 3.18.9-031809-generic.
-patch applied.

Much better now. However, crashes still occur:e.g.
-sudo rmmod wl cfg80211
-sudo modprobe wl  results in a crash.

workaround:
-sudo modprobe cfg80211
wait for abount 10 seconds
-sudo modprobe wl


But still there is a minor problem with suspension.


Just to add confirmation that I was seeing the kernel panics on a Dell XPS 13 
Developer Edition after upgrading to 15.04 (BIOS A04), and after applying 
Jesse/PierreF's patch, suspend/resume is now working fine.

The patch from #27 appears to have fixed the kernel panics on suspend for me as 
well on my Dell XPS 13 Developer Edition (2015 edition) with Ubuntu 15.04 and 
BIOS A04. Have not seen a panic in five days while before I could not go more 
than one day without it.


I'll be providing a PPA with the fix and asking for feedback. If the
suspend problems still occur we will continue from there. Expect a PPA
provided here soon. BTW, I'll provide fixes for Trusty  Vivid only
since Utopic is not supported anymore.

Thank you

We have a problem introduced in between:

bcmwl-kernel-source | 6.30.223.141+bdcom-0ubuntu2

and

bcmwl-kernel-source | 6.30.223.248+bdcom-0ubuntu0.1
bcmwl-kernel-source | 6.30.223.248+bdcom-0ubuntu2
bcmwl-kernel-source | 6.30.223.248+bdcom-0ubuntu4


2. On checking syslog carefully, the Scan_results errors are often associated 
with the system running slowly and [TTM] Out of kernel memory messages being 
logged.

https://bugs.launchpad.net/ubuntu/+source/bcmwl/+bug/1415880/comments/15

I'm now on vivid (via do-release-upgrade -d), The problem reappears
without the patch. I am now reapplying the patch and see if it works
out. On vivid, with the patch, I still get the warning, but the
connection doesn't drop (at least for now, fingers crossed).

this patch fixes kernel crashes with kernels =3.18 for me on BCM43228.
I'm currently using it on top of vivids bcmwl-kernel-source: 
6.30.223.248+bdcom-0ubuntu2 and the vivid 3.19.0 kernel


It looks like the patch fixes the out of memory problem.


-kernel 3.18.9-031809-generic.
-patch applied.

Much better now. However, crashes still occur:e.g.
-sudo rmmod wl cfg80211
-sudo modprobe wl  results in a crash.

workaround:
-sudo modprobe cfg80211
wait for abount 10 seconds
-sudo modprobe wl


But still there is a minor problem with suspension.


Just to add confirmation that I was seeing the kernel panics on a Dell XPS 13 
Developer Edition after upgrading to 15.04 (BIOS A04), and after applying 
Jesse/PierreF's patch, suspend/resume is now working fine.

The patch from #27 appears to have fixed the kernel panics on suspend for me as 
well on my Dell XPS 13 Developer Edition (2015 edition) with Ubuntu 15.04 and 
BIOS A04. Have not seen a panic in five days while before I could not go more 
than one day without it.


I'll be providing a PPA with the fix and asking for feedback. If the
suspend problems still occur we will continue from there. Expect a PPA
provided here soon.

Thank you

[Kernel-packages] [Bug 1415880] Re: 14e4:4365 bcmwl-kernel source: fix for null pointer crash

[Rafael David Tinoco]

Okay, so after reading all the bug I have the following summary:


1. The current trusty repository bcmwl-kernel-source 
6.30.223.141+bdcom-0ubuntu2 is used on my wife's laptop. This system is not 
experiencing null pointer crashes OR Scan_results errors. This evidence 
strongly suggests both problems were introduced with 
6.30.223.248+bdcom-0ubuntu1.


We have a problem introduced in between:

bcmwl-kernel-source | 6.30.223.141+bdcom-0ubuntu2

and

bcmwl-kernel-source | 6.30.223.248+bdcom-0ubuntu0.1
bcmwl-kernel-source | 6.30.223.248+bdcom-0ubuntu2
bcmwl-kernel-source | 6.30.223.248+bdcom-0ubuntu4


2. On checking syslog carefully, the Scan_results errors are often associated 
with the system running slowly and [TTM] Out of kernel memory messages being 
logged.

I'm now on vivid (via do-release-upgrade -d), The problem reappears
without the patch. I am now reapplying the patch and see if it works
out. On vivid, with the patch, I still get the warning, but the

is not supported anymore.

[Kernel-packages] [Bug 1415880] Re: 14e4:4365 bcmwl-kernel source: fix for null pointer crash

[monochromec]

Please note that the null pointer crash is only required for kernels =
3.18. I can confirm that the patch is working on both unicorn and vivid
releases.

@Hugo: Just follow the instructions at the beginning of the bug report A
somewhat different approach using dkms is described in a duplicate bug
report I filed some time ago
(https://bugs.launchpad.net/ubuntu/+source/bcmwl/+bug/1451789).

@PierreF: I had similar problems when suspending a MBP (which uses a BCM
4331), albeit the driver would stop working rather then causing a kernel
panic upon wake-up. Removing the driver before suspending and inserting
it once again upon wake-up did the trick for me. The implementation of
this is straight forward: just put a similar script to the following in
/lib/systemd/system-sleep

#!/bin/bash
MA=$(uname -r | awk -F'.' '{ print $1 }')
if [ $MA -ge 4 ] ; then
if [ $1 = pre ] ; then
rmmod wl
else
modprobe wl
fi
fi

Cf. for the systemd power management documentation for the details.

  random disconnects, poor wifi signal and kernel warnings, See also
  #1379524.

  Adding the patch is a fairly simple process:

  * put the patch file in /usr/src/bcmwl-6.30.223.248+bdcom/patches
  * add the following line to  /usr/src/bcmwl-6.30.223.248+bdcom/dkms.conf

  * run: /usr/lib/dkms/common.postinst bcmwl 6.30.223.248+bdcom 
/usr/share/bcmwl x86_64 $(uname -r)

  This has fixed the issue for me. Edit: I just wanted to add that I did
  not write the patch; I merely downloaded it from a paste that was

[Markus W]

The patch from #27 appears to have fixed the kernel panics on suspend
for me as well on my Dell XPS 13 Developer Edition (2015 edition) with
Ubuntu 15.04 and BIOS A04. Have not seen a panic in five days while
before I could not go more than one day without it.

Just to add confirmation that I was seeing the kernel panics on a Dell

applying Jesse/PierreF's patch, suspend/resume is now working fine.

[Kernel-packages] [Bug 1415880] Re: 14e4:4365 bcmwl-kernel source: fix for null pointer crash

[Paweł]

This patch fixed my problems.

System information:

* Hardware : HP EliteBook 2570p
* Ubuntu 14.04 amd64
* Bios 68ISB Ver. F.40
* bcmwl-kernel-source 6.30.223.248+bdcom-0ubuntu2
* lspci : Broadcom Corporation BCM43228 802.11a/b/g/n

There were no problems on driver version: 6.30.223.141+bdcom-0ubuntu2, but this 
I was using with kernel 3.16.
After compiling 3.17 and above I started to use b43 drivers, and there were 
working unless I was more than 2 meters from AP - then connections was started 
to drop every couple minutes.

Now Im using kernek 3.19 with wl module and this patch and its
working.

[Kernel-packages] [Bug 1415880] Re: 14e4:4365 bcmwl-kernel source: fix for null pointer crash

[PierreF]

I have null pointer exception on a XPS 13 (9343) which trigger a kernel
panic when I suspend the laptop. I can reproduce the issue nearly all
times (3 / 4 tries), for this I need to generate network traffic
(looking a video on Internet seem to be enough).

After applying the patch mentioned above, I not longer have such kernel
panic (done 6 tries without any kernel panic). So that patch seems to
solve my kernel panic issue when suspending laptop.

I will attach the debdiff I used to apply the patch.


Without the patch (with bcmwl-kernel-source 6.30.223.248+bdcom-
0ubuntu2), I could product a kernel panic by doing:

* Have network load (watching video on internet, downloading something, ...)
* Suspend the laptop. On my test I did it with systemctl suspend from tty1 to 
capture the Call trace.

System information:

* Hardware : Dell XPS 13 (9343)
* Ubuntu 15.04 amd64
* Bios A03 03/25/2015
* bcmwl-kernel-source 6.30.223.248+bdcom-0ubuntu2  (so wifi is using module wl)
* lspci : 02:00.0 Network controller: Broadcom Corporation BCM4352 802.11ac 
Wireless Network Adapter (rev 03)

I will also attach picture of the screen after a crash + partial
transcript the of kernel panic (see picture for the full information).

This patch worked for me also, but I also had to run update-initramfs.

  The bcmwl package as of now misses one patch for a bug that occurs

  Adding the patch is a fairly simple process:

  * put the patch file in /usr/src/bcmwl-6.30.223.248+bdcom/patches

/usr/share/bcmwl x86_64 $(uname -r)

  This has fixed the issue for me. Edit: I just wanted to add that I did
  not write the patch; I merely downloaded it from a paste that was
  linked from the respective AUR package.

[Sergey Talchuk]

-kernel 3.18.9-031809-generic.
-patch applied.


Much better now.  However, crashes still occur:e.g.
-sudo rmmod wl cfg80211
-sudo modprobe wl   results in a crash.

workaround:
-sudo modprobe cfg80211
wait for abount 10 seconds
-sudo modprobe wl

Looking forward to new patches )

[Kernel-packages] [Bug 1415880] Re: 14e4:4365 bcmwl-kernel source: fix for null pointer crash

[Luis Alvarado]

Confirming this issue with the Lenovo Z510. The wireless works randomly.
All the problems mentioned here actually happen on this model. Between
slow connection, not seeing 5ghz, dropping packets, dropping connection
I actually thought I had problems with the laptop but after checking
another 5 similar models, all had the same behavior.

I am using Vivid 15.04 and the latest 3.19 kernel version as of right
now.

Linux cyrex 3.19.0-9-generic #9-Ubuntu SMP Wed Mar 11 17:50:03 UTC 2015
x86_64 x86_64 x86_64 GNU/Linux


I have not tried the patch yet but will proceed and give feedback.

[Kernel-packages] [Bug 1415880] Re: 14e4:4365 bcmwl-kernel source: fix for null pointer crash

[Martin Oemus]

I had the same issues like #15, the path here didn't help. I'm still
working on trusty. Because the old version worked flawlessly, I
downloaded the package 6.30.223.141+bdcom-0ubuntu2 from
http://www.ubuntuupdates.org/package/core/trusty/restricted/base/bcmwl-
kernel-source and used dpkg to downgrade to this older version. Then I
used

sudo apt-mark hold bcmwl-kernel-source

to prevent any problems in the future.

Title:
  14e4:4365 bcmwl-kernel source: fix for null pointer crash

Status in bcmwl package in Ubuntu:
  Incomplete

Bug description:
  The bcmwl package as of now misses one patch for a bug that occurs
  with BCM43142 and possibly other broadcom chipsets that will look like
  random disconnects, poor wifi signal and kernel warnings, See also
  #1379524.

  Adding the patch is a fairly simple process:

  * put the patch file in /usr/src/bcmwl-6.30.223.248+bdcom/patches
  * add the following line to  /usr/src/bcmwl-6.30.223.248+bdcom/dkms.conf
  PATCH[7]=0014-null-pointer-crash.patch
  * run: /usr/lib/dkms/common.postinst bcmwl 6.30.223.248+bdcom 
/usr/share/bcmwl x86_64 $(uname -r)

  This has fixed the issue for me. Edit: I just wanted to add that I did
  not write the patch; I merely downloaded it from a paste that was
  linked from the respective AUR package.

[Kernel-packages] [Bug 1415880] Re: 14e4:4365 bcmwl-kernel source: fix for null pointer crash

[Andre Bogus]

That's too bad. I'm one step from updating to vivid. One interesting
tidbit I found in dmesg output:

[   11.564768] wlan0: Broadcom BCM4365 802.11 Hybrid Wireless Controller
6.30.223.248 (r487574)

Is BCM4365 an alias? Or what could be the reason for this?

[Andre Bogus]

Sergey, that is very much possible.

I'm now on vivid (via do-release-upgrade -d), The problem reappears
without the patch. I am now reapplying the patch and see if it works
out.

[Andre Bogus]

Christopher M. Penalver, the output is:

8DCN40WW
10/24/2014

Interestingly, the version coincides with the version information on the
Lenovo site (where I downloaded the update), but the date is one day and
one month earlier than the date on the Lenovo site.

Upon further testing, the problem persists with or without the patch
applied. Please note that in the meantime, I did an apt-get upgrade,
which installed the new 3.16.0-30-generic kernel,.

I'm going to try updating to vivid during the next days.

[Kernel-packages] [Bug 1415880] Re: 14e4:4365 bcmwl-kernel source: fix for null pointer crash

[Brian Burch]

Thanks for your helpful comment Christopher.

However, I am inclined to believe the symptoms I've reported here are
not connected to my original bug report
(https://bugs.launchpad.net/ubuntu/+source/bcmwl/+bug/1360783).

I continue to think my symptoms are either related to this current bug,
or represent yet another bug. Given the fact that we are patching a
version of bcmwl-kernel-source that has not yet been officially released
for a production version of ubuntu, I will stay out of this discussion
for the moment. If my symptoms prove to be relevant, then at least they
are documented here (already) for the developers to consider.

As a lower priority task, I will also set up a test vivid system and see
what happens in my particular environment.

[Kernel-packages] [Bug 1415880] Re: 14e4:4365 bcmwl-kernel source: fix for null pointer crash

[Andre Bogus]

Hi again,

this took some time. I had to dig up a Windows 7 Rescue CD from
somewhere, change my BIOS settings to activate legacy support (otherwise
it would not boot), then start the BIOS update utility. Those were some
tense 30 seconds. Afterwards, it rebooted into Windows, which I exited,
rebooting again only to find out that either the Windows or the BIOS
update had somehow mangled my grub partitions. With a vivid USB stick, I
was able to make it boot again.

Long story short, the error reappeared promptly. So, now I'm on 8DCN40WW
(and we can probably remove the BIOS-outdated tag).

I'm going to do some more testing, perhaps upgrading to vivid.

Brian Burch, as you have a different WiFi chipset and underlying
hardware as the original reporter, it would be best for now to comment
in the report you already made.

[Kernel-packages] [Bug 1415880] Re: 14e4:4365 bcmwl-kernel source: fix for null pointer crash

[Brian Burch]

I need advice on whether I should be opening a new bug, or is it OK to
stay with this one?

On further investigation, I have noticed three things:

1. The current trusty repository bcmwl-kernel-source 6.30.223.141+bdcom-
0ubuntu2 is used on my wife's laptop. This system is not experiencing
null pointer crashes OR Scan_results errors. This evidence strongly
suggests both problems were introduced with 6.30.223.248+bdcom-0ubuntu1.

2. On checking syslog carefully, the Scan_results errors are often
associated with the system running slowly and [TTM] Out of kernel
memory messages being logged. The victim is the ATI radeon drm
driver, but I suspect the bcmwl scan errors are causing the driver to
not release kernel memory it has used for its wlan scan. Usually, I have
to reboot the system to restore normal performance. I have attached an
appropriate syslog extract. (note: when searching for these display-
related messages I hit very old bugs that were never explicitly
resolved).

3. I turned wifi off 12 hours ago and have been running the system via
its ethernet adapter (incidentally, also from Broadcom). Syslog doesn't
contain ANY out of kernel memory errors and system performance is back
to normal and stable.


** Attachment added: syslog extract showing kernel memory depletion
