severity 525144 important
retitle 525144 libfakeroot segfaults when building kernels in parallel
reassign 525144 fakeroot
thanks
Hi,
This is true for kernel-package version 12.009. I am putting in
a work around in kenrel-package 12.010.
Either when DEB_BUILD_OPTIONS=parallel=3, or wehn
CONCURRENCY_LEVEL=3 is set in /etc/kernel-pkg.conf, calling
make-kpkg --rootcmd=fakeroot buildpackage
fails with a seg fault.
| | serial build | parallel build |
|---------------+--------------+----------------|
| fakeroot | Success | *Failure* |
| sudo | Success | Success |
| build as root | Success | Success |
|---------------+--------------+----------------|
It seems pretty clear that there is some interaction with
fakeroot and the buildpackage target.
kernel_image, kernel_headers, and most non-buildpackage targets have
this calling pattern:
make-kpkg -> ./debian/rules <target> -> fakeroot make <some target>
This works no matter what, serial or parallel.
With buildpackage, things get a little more complex.
make-kpkg --> ./debian/rules buildpackage -> dpkg-buildpackage -->
fakeroot ./debian/rules <some target>
This works when we are not building in parallel, fails when we
are.
Now, sudo works just fin in either case, so it is not a make
fault or a kernel-package fault that I can see, though I can just
disable parallel builds when buildpackage is the target.
