[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] [Xen-devel] segfault bug in xeno-unstable...
The actual version of xeno-unstable (Changeset 1.506) segfaults with some standard commands - at least with my RedHat V8 (I haven't tested RedHat V9 yet) installation. If you enter "vi" or "vim" or "rpm -qa" as root or non-root user, xeno-linux just segfaults with no further comments (the next line of output just shows "Segmentation fault", nothing more). BTW: Especially for production use, it would be nicer if xen could somehow pass up "printk"-output in xen to dom0's kernel logger, so that you don't need to configure and run a second machine for the serial line debug output all the time. While checking the segfault bug, I have not connected a debug machine to the serial line, so I don't know if it would have showed something helpful :-( After a lot of tests with bk pull and bk undo, I was able to find out, that this bug was introduced with Changeset 1.478. Changesets up to 1.477 are working OK, without the segfaults, but starting with CSet 1.478 you get the segfault. I wasn't able and didn't try to find the cause for that, because a lot of sophisticated stuff got checked in with CSet 1.478. Perhaps somebody from the Xen Project team can check it out - and also if they get segfaults too when using the above commands on newer xeno-unstable versions ;-) I am sure there are also other command / programs segfaulting (e.g. "gdm" also did it) so this is not just an issue restricted to vi and rpm ;-) Another thing I realized while compiling and trying to load the HyperSCSI kernel module: When loading the HyperSCSI client kernel module (which was compiled against xeno-linux), it complains about 2 undefined Kernel Symbols: do_hypervisior_callback and HYPERVISOR_shared_info After adding 2 EXPORT_SYMBOL lines for these symbols in ../arch/xeno/kernel/i386_ksyms.c and recompiling the kernel, everything loaded and worked OK. I hope it was not against xen design principles to add the 2 EXPORT_SYMBOL lines ;-) I had not yet the time to check the new vbd patches together with HyperSCSI, because the segfault bug was delaying me; perhaps I'll do it on monday or tuesday. Regards + many thanks to the Xen project team for this nice and professional software :)) Sven -- NEU FÜR ALLE - GMX MediaCenter - für Fotos, Musik, Dateien...
