[Bug 1583237] Re: lxc-attach strange tty behavior (kills command) when stderr is redirected to a file

[Bug 1583237] Re: lxc-attach strange tty behavior (kills command) when stderr is redirected to a file
** Description changed: On a fresh Ubuntu 16 release, commands started by lxc-attach such as dd are being killed WHEN REDIRECTING stderr (to a file), and lxc-attach return a zero status. Command works fine without the redirection. This scenario is working on Ubuntu 15 with previous lxc release, but not on new LXC 2.0.0 (same issue on 2.0.1 too) sudo apt-get -y install lxc sudo lxc-create -n utest -t ubuntu -- -a amd64 -b $USER sudo lxc-start -d --name utest sudo lxc-attach -n utest -- dd if=/dev/zero of=/tmp/foo bs=1M count=10 2>/tmp/bar sudo lxc-attach -n utest -- ls -lh /tmp/foo -rw-r--r-- 1 root root 0 May 18 05:46 /tmp/foo - Might be related to bug 1553097 + Might be related to bug 1553097 (and/or + https://github.com/lxc/lxc/pull/873) NOTE: Sometimes the "sudo lxc-attach -n utest_bizio_tests -- ls -lh /tmp/foo" ALSO does not return anything (no output) I'm available for any additional info. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1583237 Title: lxc-attach strange tty behavior (kills command) when stderr is redirected to a file To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/autopkgtest/+bug/1583237/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
