Description Sinny Kumari 2016-01-13 16:45:22 UTC

strace fails to build on Fedora rawhide, s390 architecture because of membarrier, userfaultfd, mlock2 and sigreturn tests failure.
Koji build link containing build failure details- http://s390.koji.fedoraproject.org/koji/taskinfo?taskID=2047711

Version-Release number of selected component (if applicable):
strace-4.11-2.fc24

Additional info:
Test membarrier, userfaultfd and mlock2 also fails on s390x architecture.

Comment 1 Sinny Kumari 2016-01-13 16:53:30 UTC

Few observations
---------------
* Building strace-4.11-2 on Fedora 23 causes only sigreturn test failure and tests membarrier, userfaultfd, mlock2 get skipped.
Koji build link - http://s390.koji.fedoraproject.org/koji/taskinfo?taskID=2051484
* Test failures are reproducible easily if built in koji. I couldn't reproduce these tests failures locally using mock.

Decoding of s390 sigreturn on recent kernels was fixed upstream by commit v4.11-149-g8493dcf. strace used to workaround a kernel bug on s390, for kernels containing commit v4.3-rc1-50-g8d4bd0e this workaround has to be reverted.

Decoding of syscalls unrecognized by the kernel on s390/s390x was fixed by upstream commit v4.11-159-g1763fa5.

Comment 4 Sinny Kumari 2016-01-14 09:24:51 UTC

Thanks Dmitry for the quick fix. With this fix, strace builds successfully on F23 and Fedora rawhide.

It will be great to have a new release of strace having these fixes included. Any plan to do a new release soon?

There are several test failures on Debian secondary architectures as well.
I'd like to do a bugfix release once they are fixed.

Could you build an updated package with just the s390 fix for Rawhide? Or I can do the update as a provenpackager if you won't object. strace is used in buildroots for important packages like coreutils and thus is blocking building Rawhide for s390(x).

I've submitted snapshot v4.11-163-g972018f to Rawhide.
