Works fine with kernel-4.20.3-200.fc29 failed since kernel-5.x.x, issue reproduced also with kernel-5.0.0-0.rc4.git3.1.fc30 https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=6baca7601bdee2e57f20c45d63eb53b89b33e816 Looks like this was changed to write-only intentionally and the code is opening with read. This is a userspace regression so I can see about getting this reverted but it also sounds like this should be fixed in targetcli as well. This is going to be fixed in kernel 5.0 https://marc.info/?l=target-devel&m=154930519830248&w=2 This report has not received an update in over 90 days.
