The buffer size for routing socket is fixed to 2048.
This patch fix it to obtain the size from OS.
This patch worked on x86 platform with NetBSD 5.0.2.
Previously, both NULL and ff:ff:ff:ff:ff:ff addr were used in various
places to indicate default/broadcast keys. Make this more consistent
and useful by defining NULL to mean default key (i.e., used both for
unicast and broadcast) and ff:ff:ff:ff:ff:ff to indicate broadcast
key (i.e., used only with broadcast).
Use NULL instead of (u8 *) "" as the seq value and make sure the
driver wrapper implementations can handle NULL value. This was
previously already done in number of places, but not everywhere.
wpa_supplicant seems to crash from time to time on a NetBSD 4.0 MIPS
platform. The root cause turned out to be a MIPS alignment issue.
In my wpa_supplicant crash case, in function
wpa_driver_bsd_event_receive (from driver_bsd.c), the buf[2048] address
is started from i.e. 0x7fffd546, which is not 4 bytes aligned. Later
when it is casted to (struct if_msghdr *), and rtm->rtm_flags is used.
rtm->rtm_flags is "int" type, but its address is not 4 bytes aligned.
This is because the start address of rtm is not 4 bytes aligned.
Unfortunately in NetBSD MIPS kernel (unlike Linux MIPS kernel emulates
unaligned access in its exception handler), the default behavior is to
generate a memory fault to the application that accesses unaligned
memory address. Thus comes the early mentioned wpa_supplicant crash. An
interesting note is when I'm using the wpa_supplicant version 0.4.9, I
never saw this problem. Maybe the stack layout is different. But I
didn't look into details.
I used below patch to resolve this problem. Now it runs correctly for at
least several hours. But you might have a better fix (maybe we can use
malloc/free so that it is at least cache line aligned?). I'm also not
sure if other drivers should have the same problem.
Previous version driver_bsd.c switches the channel in
wpa_driver_bsd_associate(). This patch changes it to use set_freq().
I have tested this patch on FreeBSD 8.0/NetBSD 5.0.2 with hostapd,
wpa_supplicant(AP) and wpa_supplicant(STA).
On NetBSD 5.0.2, wpa_supplicant build results in messages below.

This patch solves this issue.
This patch allows wpa_supplicant to compile on Debian's kfreebsd
architectures.
Patch by Stefan Lippers-Hollmann based on work done by Petr Salinger
and Emmanuel Bouthenot for 0.6.X (http://bugs.debian.org/480572).
This patch aggregates ioctls.
First is SIOCS80211. The SIOCS80211's arguments has 3 couples.
1-1. i_len, i_data
1-2. i_val
1-3. i_len, i_data, i_val (currently only IEEE80211_IOC_APPIE)
There were 3 routines for each cases. This patch aggregates these to
one.
Second is SIOCG80211. The SIOCG80211 returns 2 type of value.
2-1. i_len
2-2. i_val
There were 2 routines for each cases. This patch aggregates these to
one.
I have tested on both FreeBSD 8.0 and NetBSD 5.0.1 with these cases.
[hostapd]
RSN-PSK(CCMP)/WPA-PSK(TKIP)
[wpa_supplicant(STA)]
RSN-PSK(CCMP)/WPA-PSK(TKIP)
[wpa_supplicant(AP)]
RSN-PSK(CCMP)/WPA-PSK(TKIP)
This patch enables FreeBSD channel control.
I have tested on FreeBSD 7.2 with these cases.
[hostapd]
RSN-PSK(CCMP)/WPA-PSK(TKIP)
[wpa_supplicant(STA)]
RSN-PSK(CCMP)/WPA-PSK(TKIP)
[wpa_supplicant(AP)]
RSN-PSK(CCMP)/WPA-PSK(TKIP)
The attached patch unifies hostapd wpa_driver_bsd_ops and
wpa_supplicant wpa_driver_bsd_ops.
I have tested on NetBSD 5.0.1 with these cases.
[hostapd]
RSN-PSK(CCMP)/WPA-PSK(TKIP)
[wpa_supplicant(STA)]
RSN-PSK(CCMP)/WPA-PSK(TKIP)
[wpa_supplicant(AP)]
RSN-PSK(CCMP)/WPA-PSK(TKIP)
This patch modifies field name of struct bsd_driver_data to use
same name of struct wpa_driver_bsd_data. This is a preparation of
unifying struct bsd_driver_data and struct wpa_driver_bsd_data.
The bsd_send_eapol() adds Ethernet header by itself. This patch changes it
to use l2_packet functionality.
I have tested on NetBSD 5.0.1 with WPA-PSK(TKIP).
On NetBSD, we should configure some parameters manually out of hostapd
like below.
ifconfig ath0 mediaopt hostap
ifconfig ath0 mode 11g
ifconfig ath0 chan 6
This patch does these automatically. Maybe there will be some
objections, like "hardware configuration is not hostapd/wpa_supplican's
work". So I will write the reasons why I made this patch.
1. For usability.
2. The first command fails when previous state is adhoc. This patch is
free from previous state.
3. Some driver wrappers configure these automatically (like nl80211).
4. I have wasted time trying to find out these command were needed :(
On FreeBSD 8.0, driver_bsd.c build fails because of changes from
older versions of FreeBSD. The error messages are below:

This patch solves this issue.
This removes need for including hostapd/sta_flags.h into driver
wrappers and removes any remaining dependencies between driver flags
and internal hostapd flags.
On NetBSD 5.0.1, driver_bsd.c build fails with message below.
../src/drivers/driver_bsd.c: In function 'wpa_driver_bsd_associate':
../src/drivers/driver_bsd.c:1170: warning: implicit declaration of function 'wpa_driver_bsd_set_auth_alg'

gmake: *** [../src/drivers/driver_bsd.o] Error 1
This patch solves this issue.
This makes it clearer which files are including header from src/common.
Some of these cases should probably be cleaned up in the future not to
do that.
In addition, src/common/nl80211_copy.h and wireless_copy.h were moved
into src/drivers since they are only used by driver wrappers and do not
need to live in src/common.
This gets rid of previously deprecated driver_ops handlers set_wpa,
set_drop_unencrypted, set_auth_alg, set_mode. The same functionality
can be achieved by using the init/deinit/associate handlers.
This code was copied from driver_hostap.c where it is used with the
special wlan#ap interface. It was not supposed to be used to change
the MTU for a normal data interface.
