The only configuration change between 0.6.10-2.1 and 0.7.3-4 affecting
kfreebsd is enabling CONFIG_IEEE80211W=y, which shouldn't have any
impact on scanning. However there have been really massive BSD related
changes in wpasupplicant between the 0.6 and 0.7 branches, including
some explicitly referencing compatibility with FreeBSD 8.0[1]. Looking
at their size and impact, just applying them to wpasupplicant 0.6.10
or doing simple backports doesn't appear to be possible or even
acceptable for upcoming squeeze stable releases, so a targetted patch
would be needed.
Unfortunately I'm only running kfreebsd-amd64/ unstable in kvm on a
linux host so far, so beyond build testing on kfreebsd I can't actually
debug kfreebsd's wlan specifics. Therefore I'd need your input for
kFreeBSD specific changes, also considering its configuration and in
particular regarding the newly (in 0.7.3-4) introduced
wpasupplicant-udeb, which should allow to use wlan/ wpa for netinstalls
in d-i (the wlan support code in d-i mostly relies on wpasupplicant
and might not need many changes to work on kFreeBSD as well).
Talking about wlan specifics, which wlan card/ kernel module are you
using to test wpa_supplicant under kFreeBSD (preferably which works
with the kernel in unstable/main and doesn't require a kernel with
unstripped firmwares)?
[ Unrelated to this, I have been playing with the idea of doing a
kFreeBSD-amd64/ unstable installation on real hardware, to allow me
some further wpasupplicant (or lirc) testing, but all of my systems
use lvm2 on top of MSDOS or GPT partition tables spanning the whole
drive (/ on lvm2, no dedicated /boot/). This configuration is
apparently not supported by Debian/ kFreeBSD yet, e.g. d-i/ partman
doesn't offer to use the volume group or existing logical volumes
therein and grub2 can't find the root device, if copied manually.
While I have tested to move kFreeBSD manually to a prepared ufs2
filesystem on top of a LVM2 logical volume, which works fine after
adapting fstab and setting
kfreebsd_module_elf /lib/modules/8.2-1-amd64/geom_linux_lvm.ko
in grub.cfg of an external grub2 install (either on a regular
partition or linux / on lvm2) in kvm, I didn't try to move such
an install to real hardware, yet. ]
