Caveat: When I reported this for the first test patchset, I was
informed that I was the only one reporting the issues in question. So
this may not apply to anyone else.
OK; as was the case for each of the test patchsets, after rebuilding the
world & kernel & rebooting the result, I see the following:
* /sbin/ifconfig dumps core.
With each of the test patchsets, I tried building a debug version of
ifconfig(8) (using "-g" as the CFLAGS value), which caused a version
of ifconfig to be installed that no longer dumps core. The following
sequence was sufficient to accomplish this:
* Modify /etc/make.conf to include the line "CFLAGS =3D -g"
* cd /usr/src/sbin/ifconfig
* touch ifieee80211.c
* make
* make install
I had spent a fair amount of time poking at this with the first test
patchset (by littering ifieee80211.c with debugging printf(3) calls).
I will be happy to pursue this further if it is likely to be of use.
* Even after installing a copy of /sbin/ifconfig that doesn't dump core,
the wi(4) NIC (which is the one I use most) does not associate to
either of my 802.11b APs (using WEP). Using the code from the first
test patchset, I was able to get an an(4) NIC to associate.=20
* I had no trouble with wired NICs ussing eh first test patchset; I
don't anticipate problems with them with the committed code.
Here's a short typescript that illustrates some of the above:
