segfault at usbmuxd startup
Reported by Bgs | April 18th, 2010 @ 08:20 PM
I had 1.0.0RC2 working, but haven't used it for a while. Today when started it segfaulted. I upgraded to 1.0.3 but it segfaults as well.
Here is the output:

It's a 64 bit build btw, but it worked like a charm before. The only notable change since last time that I recall is the upgrade to kernel 2.6.33

- Tag cleared.
The formatting was ugly, so here is the relevant debug output again:

I can confirm this bug, i also read this thread:
http://lists.mattcolyer.com/private.cgi/iphone-linux-dev-mattcolyer...
in the mailing list but i checked these option, and they are disabled in my kernel (2.6.33.2)I didn't try either on older kernel or older version of usbmuxd, but i tried the git one...
I'm using Gentoo 64 bit.

I reinstalled the 2.6.32 kernel and I also tried different cables (both from @pple, not cheap cables) but there is the same problem.

Please verify with usbmuxd 1.0.4 which fixes a few issues. If it's still an issue please reopen. Thanks.

Still a problem with me as of usbmuxd 1.0.4. Running Gentoo 64-bit, 2.6.33-r2.

Can you verify on 1.0.4 using "sudo usmbuxd -vvv -f" and perhaps even increase verbosity to get more information after the "Connecting to new device on location ..." line?
Also what does the syslog contain at the time of startup?
Did you compile yourself or use some packages (in that case please post from where)?
Which device model and firmware version?
Did you try a different USB hub/port?

Log of what happens with usbmuxd now. Compiled myself. Using iPod touch 3G, 3.1.3. Different USB port, same results.
It's odd; it only segfaults with -vv or below, not -vvv.

Aha. It seems to segfault right away if the device is attached whilst running usbmuxd, but running usbmuxd then plugging it in results in the above log. Here is some stuff from the syslog:

I'm getting what looks like the same error:

I'm pretty sure this is a kernel/other part of system bug, because I get the same error with a ubuntu binary that works on another machine. I'm running 32-bit gentoo, 2.6.34 on an eeepc 1005ha.

This appears to be a libusb-1.0 issue: http://www.libusb.org/ticket/20
Either try with the patch attached to the ticket or lookout for updated libusb packages (1.0.8) for your distro. Also please try usbmuxd git master which has a fix for the segfault which should not happen even with this issue.
I'll keep this on hold until someone verifies that the patch fixes this issue (resolved) or reopens due to still seeing that bug with the patch applied (open).
Thanks for your reports. :)

Thanks for the quick reply, I have it working perfectly with libusb-1.0.8 (1.0.7 was broken).

Ok, thanks for testing! Marking as resolved unless someone reopens.
