Comment (by anonymous):
I'm not sure if it's the same problem. I found it in such a setup: My AP,
which is MIPS running Linux 2.6.18, continually scan in a complex radio
environment with lots of AP and STA for several days. It seems different
from yours.
A suggestion:
cat /proc/slabinfo. Its output shows malloc'd memory size and counts. You
should get two records before and after you tests. If the count of
"size-32"(or "kmalloc-32") grows huge, this patch may solve your issue.

> I'm also having memleak problems which seem to come from madwifi, I have
them with 0.9.4 from svn or current trunk (madwifi-free) I'm currently
running the machine without madwifi to see if it was really madwifi the
one that was causing the leak and it seems so.

> I'm wondering if this patch could solve my issues with madwifi, I'll try
to describe my setup so that you can tell me if my problem could be the
same as the one you are fixing here.
>
> My server has a madwifi driven card which is setup as a sta (using wpa2)
of another AP and acts itself as an AP for two different networks, one
with wpa2 and the other open. So, it has two APs and a client on the same
card. I'm using Debian Lenny o a Pentium III running 2.6.31.3 with hostapd
for the wpa2 AP and wpasupplicant for the client.

able to get back to the madwifi setup and test your patch for some days.
