[Bug 414724] Re: wl driver (Broadcom) does not receive ARP packets (broadcasts)
I believe I'm affected by this bug. I'm running Ubuntu 13.04 Raring
Ringtail on a Lenovo S10-3 ideapad (netbook) with a 32-bit processor and
the Broadcom BCM4313 chipset. I have the bcmwl-kernel-source package
installed. For other non-professional users of Ubuntu, to figure out
what wireless chipset you have follow the instructions here:
https://help.ubuntu.com/community/WifiDocs/Driver/bcm43xx , and to find
out what packages are installed go here:
http://askubuntu.com/questions/17823/how-to-list-all-installed-packages
.
My computer ignores broadcast ARP requests, which breaks ping and Samba.
My troubleshooting process is described here:
http://ubuntuforums.org/showthread.php?t=2172373&p=12778960#post12778960
. I'll try the work-around of adding a static ARP entry for all the
other computers on my network. I've been running the current release
versions of Ubuntu since 2010, and ping and Samba worked until I loaded
Ubuntu 13.04 Raring Ringtail. I suppose I got a new version of the
driver with the bug in it when I upgraded from Ubuntu 12.10 Quantum
Quetzal.

Title:
wl driver (Broadcom) does not receive ARP packets (broadcasts)
Status in “bcmwl” package in Ubuntu:
Confirmed
Bug description:
It seems that the wl driver in kernel-2.6.28-14 restricted modules
(x86_64) does not receive ARP broadcast packets (possibly, it does not
receive broadcast packets at all).
Symptom: have two hosts A (your machine with wl and Broadcom) and B on
the same Ethernet network. Boot them up. Do *not* connect or ping B
from A. At this point, the ARP cache on B does not know the MAC
address for A. Try ssh from B to A, it won't find the host. Do a
single ping from A to B (which creates an entry for A in B's ARP
cache). ssh from B to A then works.
The problem can of course be worked around by hardcoding the MAC
address of the Broadcom/wl host in the ARP caches of the other
machines on the network, but this is quite unwieldy.
I suspect the driver does not process Ethernet broadcasts, but I may
be wrong (I haven't checked).
