Bug#601803: kfreebsd-image-8.1-1-686: ifconfig wlan0 create wlandev ath0 = SIOCIFCREATE2: Bad address
libbsdxml is just normal expat with different name. Also, libjail and libsbuf seem relatively small. Would it make sense to just package these separately and have freebsd-utils build-depend on them? Note that libsbuf is packaged already (it's in freebsd-libs). As for libbsdxml, perhaps it'd be useful if libexpat provided a compatibility symlink? -- Robert Millan -- To UNSUBSCRIBE, email to debian-bsd-requ...@lists.debian.org with a subject of unsubscribe.

Hi, I think this is caused by the fact that ifieee80211.c is not compiled at all(!). The old build log https://buildd.debian.org/fetch.cgi?pkg=freebsd-utilsver=7.2-9arch=kfreebsd-i386stamp=1256686015file=log shows cc -Wall -g -pipe -fPIC -I. -D_GNU_SOURCE -D#39;__FBSDID(string)=#39; -O2 -Wall -Wmissing-prototypes -Wcast-qual -Wwrite-strings -Wnested-externs -Wall -g -pipe -fPIC -I. -D_GNU_SOURCE -D#39;__FBSDID(string)=#39; -O2 -c ifieee80211.c but https://buildd.debian.org/fetch.cgi?pkg=freebsd-utilsver=8.0-7arch=kfreebsd-i386stamp=1264384567file=log does not show it anymore. -- To UNSUBSCRIBE, email to debian-bsd-requ...@lists.debian.org with a subject of unsubscribe.

where if_iterate (if_fn fn, void *private) does buf = alloca (bufsize); if (__sysctl (request, 6, buf, bufsize, NULL, 0) = 0) Are you still saying that it should pass zero as third argument? No ;-) The code is different on plain FreeBSD and GNU/kFreeBSD. The FreeBSD one 1st passes zero, to get right buffer size, while our code uses doubling of buffer size. Sorry, wrong guess. BTW, for your pet project, the kernel syscall convention on kfreebsd-amd64 is the same as syscall convention on (linux-)amd64: syscall number rax arg 1 rdi arg 2 rsi arg 3 rdx arg 4 r10 arg 5 r8 arg 6 r9 Petr -- To UNSUBSCRIBE, email to debian-bsd-requ...@lists.debian.org with a subject of unsubscribe.

I downloaded ftp://ftp.freebsd.org/pub/FreeBSD/releases/i386/ISO-IMAGES/8.1/FreeBSD-8.1-RELEASE-i386-disc1.iso and combined the base.?? files as http://lindi.iki.fi/lindi/kfreebsd/freebsd-8.1-release-i386-base.tar.bz2 which I extracted to /root/freebsd-8.1-release-i386-base and added /usr/local/bin/freebsd wrapper that contains #!/bin/sh exec chroot /root/freebsd-8.1-release-i386-base $@ and lets me do # freebsd ifconfig wlan0 create wlandev eth0 which does not fail with SIOCIFCREATE2. = this looks like a userland bug in debian. -- To UNSUBSCRIBE, email to debian-bsd-requ...@lists.debian.org with a subject of unsubscribe.

Package: kfreebsd-image-8.1-1-686

[ this is resend #1 since I did not receive any reply in hours

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

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).
