Package: kfreebsd-image-8.1-1-686
Version: 8.1-5
Severity: normal

ifconfig wlan0 create wlandev ath0

fails with

ifconfig: SIOCIFCREATE2: Bad address

on my aspire one laptop. I recompiled freebsd-utils with debugging
symbols and set a breakpoint at ifclone.c just before

if (ioctl(s, SIOCIFCREATE2, &ifr) < 0)

Here gdb shows the ifr as

(gdb) p ifr
$1 = {ifr_name = "wlan0\000\000\000\000\000\000\000\000\000\000", ifr_ifru = {ifru_addr = {sa_len = 0 '\000', sa_family = 0 '\000', sa_data = '\000' <repeats 13 times>}, ifru_dstaddr = {sa_len = 0 '\000', sa_family = 0 '\000', sa_data = '\000' <repeats 13 times>}, ifru_broadaddr = {sa_len = 0 '\000', sa_family = 0 '\000', sa_data = '\000' <repeats 13 times>}, ifru_netmask = {sa_len = 0 '\000', sa_family = 0 '\000', sa_data = '\000' <repeats 13 times>}, ifru_buffer = {length = 0, buffer = 0x0}, ifru_flags = {0, 0}, ifru_index = 0, ifru_jid = 0, ifru_metric = 0, ifru_mtu = 0, ifru_phys = 0, ifru_media = 0, ifru_data = 0x0, ifru_cap = {0, 0}}}

I then recompiled kfreebsd-8 with debugging symbols and DDB/KDB
support (and documented this as
http://wiki.debian.org/Debian_GNU/kFreeBSD_FAQ#Q.HowdoIdebugthekernel.3F
) and saw that copyin() in wlan_clone_create() fails since its third
argument, caddr_t params, contains just 0x10 which can not be a valid
pointer.

"trace" shows that the third argument of ifioctl is 0xc32477e0 so I
dumped its contents with the kernel debugger. Unfortunately I do not
know how to save debugger output to a file so I took a photo of the
screen instead (see the attached 41KB png file).

TBH, I don't really know.  It was marked as fixed and later unmarked
as a result of my control request [1], but it's clearly not what I
intended.

In any case, it was indeed fixed with 8.2+ds1-1.  Sorry about this confusion.
