Title:
BCM4313 ignores ARP broadcast packets
Status in “bcmwl” package in Ubuntu:
Incomplete
Bug description:
I'm running ubuntu server 12.04 on a netbook with a Broadcom BCM4313
wireless chip. I had the wl.ko driver installed by compiling the
bcmwl-kernel-source package, and everything was good in the world.
Then, yesterday, I did a dist-upgrade, and the machine now no longer
responds to ARP broadcast packets. Consider two machines- the affected
netbook A, and my other windows machines B and C. If I try and ping A
from B, I get "destination host unreachable". Wireshark on B shows ARP
broadcast packets going out, but tcpdump on A does not see these
packets.
If I then ping B from A, I see an ARP broadcast from A asking "Who has
B? Tell A", which B responds to. B then sends a "Who has A? Tell B"
message, but directs this specifically to A's MAC address and not the
broadcast MAC. A responds to this message, and the pings succeed.
Because B's ARP table has been filled in this process, pings from B to
A now work too- but pings from C to A still fail.
The inability to do inbound connections seems like a pretty big
showstopper for a server! This is possibly related to this:
