Note: This bug is displayed in read-only format because the product is no longer active in Red Hat Bugzilla.
RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

FAIL ioctl_evdev-success.test (exit status: 1)

These failures occur only in tests-m32/ run, not in tests/. They were also not reproducible in other rhel-7.7 supported arches.

Version-Release number of selected component (if applicable):
devtoolset-9-strace-5.1-1.el7.x86_64
RHEL-7.7-updates-20190813.0

Steps to Reproduce:
1. rpm -ivh devtoolset-9-strace-5.1-1.el7.src.rpm 
2. rpmbuild -bc rpmbuild/SPECS/strace.spec 
3. make -C rpmbuild/BUILD/strace-5.1/ -k check RUNTESTFLAGS="--tool_exec=/opt/rh/devtoolset-9/root/usr/bin/strace"

--- Additional comment from Eugene Syromiatnikov on 2019-08-29 10:02:47 UTC ---

A side note: strace does not use dejagnu framework (to which "--tool_exec" option and RUNTESTFLAGS are specific), but rather generic automake-provided test invocation infrastructure with a standard test driver. It is still, however, possible to override path to the strace binary with STRACE variable (see tests/init.sh file in strace repository): "make -j6 -C rpmbuild/BUILD/strace-5.1/ -k check STRACE=/opt/rh/devtoolset-9/root/usr/bin/strace".

The other thing is that in addition to build dependencies (and devtoolset-9-strace itself), glibc-devel.i686 and libgcc.i686 have to be installed.
Comment 2 Eugene Syromiatnikov 2019-08-29 16:16:02 UTC 
For RHEL 7 strace, there are some additional missing changes:

 * 0002-evdev-fix-decoding-of-EVIOCGBIT-0.patch: tests-m32/ioctl_evdev.c, tests-mx32/ioctl_evdev.c
 * 0023-tests-move-PTRACE_SEIZE-check-to-a-separate-file.patch: tests-mx32/PTRACE_SEIZE.sh
 * 0025-tests-check-tracing-of-looping-threads.patch: tests-m32/looping_threads.test, tests-mx32/looping_threads.test
Comment 4 Edjunior Barbosa Machado 2019-10-16 14:16:36 UTC 
Verified that the aforementioned testcases ran successfully with strace-4.24-4.el7 on RHEL-7.8-20191015.n.0:

PASS: ioctl_evdev-success.test
PASS: ioctl_evdev-success-v.test
