Seems to work fine on all 64 bit arches. If you decide not to fix this on 32 bit, please add ExcludeArch: i686 in the spec file. I mean ExcludeArch: %{ix86}
FEDORA-2023-e2392c8748 has been submitted as an update to Fedora 39. https://bodhi.fedoraproject.org/updates/FEDORA-2023-e2392c8748 FEDORA-2023-e2392c8748 has been pushed to the Fedora 39 stable repository. If problem still persists, please make note of it in this bug report. This bug got associated with the wrong bodhi update ... This bug appears to have been reported against 'rawhide' during the Fedora Linux 39 development cycle. Changing version to 39. I can't reproduce this in mock, so I'm going to go back and see if it still happens inside Koji. In the meantime since it took me so long to work this out, here are the steps for testing with a i686 userspace in mock: (1) Install 'mock', add yourself to the 'mock' group. (2) Install 'fedora-packager' and check out the nbdkit sources: $ fedpkg clone -B -a nbdkit $ cd nbdkit/rawhide (3) Apply this patch to nbdkit to enable libblkio support: diff --git a/nbdkit.spec b/nbdkit.spec index 2e4f8a6..0e638d1 100644 --- a/nbdkit.spec +++ b/nbdkit.spec @@ -23,11 +23,7 @@ # We don't yet have libblkio on RHEL. # libblkio is broken on i686: https://bugzilla.redhat.com/2229372 -%if !0%{?rhel} -%ifnarch %{ix86} %global have_blkio 1 -%endif -%endif (4) Build the SRPM: $ fedpkg srpm (5) Build nbdkit in the 32 bit chroot: $ mock -r fedora-39-i386 --rebuild nbdkit-1.36.0-1.fc40.src.rpm --no-cleanup-after --nocheck (6) Go into the chroot and look around: $ mock -r fedora-39-i386 --shell --no-clean <mock-chroot> sh-5.2# ls build/ <mock-chroot> sh-5.2# uname -a Linux f86cb57f19a1422eb8a946b127c5349e 6.3.7-200.fc38.x86_64 #1 SMP PREEMPT_DYNAMIC Fri Jun 9 15:21:11 UTC 2023 i686 GNU/Linux <mock-chroot> sh-5.2# file /bin/ls /bin/ls: ELF 32-bit LSB pie executable, Intel 80386, version 1 (SYSV), dynamically linked, interpreter /lib/ld-linux.so.2, BuildID[sha1]=fc509e8af5a5160bc060ca9aa545e73f790a32af, for GNU/Linux 3.2.0, stripped (7) Run the program which (should) fail: # cd /builddir/build/BUILD/nbdkit-1.36.0 # truncate -s 1G /var/tmp/disk # ./nbdkit -r blkio io_uring path=/var/tmp/disk --run 'nbdinfo "$uri"' Welp, it has "fixed itself" somehow: PASS: test-blkio.sh |
