Still there in 14.04. Please be advised, this bug breaks the SSH ControlMaster feature, which in turn breaks Android builds.
I am trying to use LXC containers (snapshot clones using overlayfs) to build Android (12.04 container on a 14.04 host). Android's build utility "repo" is a python script that uses SSH with an SSH ControlMaster (shared SSH session using a FIFO socket). It creates a master connection like this: ssh -M -N -p 29422 -o ControlPath=/tmp/ssh-ujjH6W/master-%r@%h:%p my- upstream-android.mirror.com ...and then it reuses that connection to do a git pull (from gerrit) for 100+ git repos (called "projects" in Android lingo). Since pipes don't work, running "./repo sync" results in a bunch of errors like this: Control socket connect(/tmp/ssh-ujjH6W/master-jenkins.fromseat...@my-upstream-android.mirror.com): Connection refused Control socket connect(/tmp/ssh-ujjH6W/master-jenkins.fromseat...@my-upstream-android.mirror.com): Connection refused Control socket connect(/tmp/ssh-ujjH6W/master-jenkins.fromseat...@my-upstream-android.mirror.com): Connection refused ...etc... This error message was hard to diagnose and find. I had to know to look for "LXC Unix Sockets", specifically leaving out the terms Android, repo, ssh, etc. Even then it was the fifth Google result down. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1214500 Title: consistent failure with overlayfs and unix sockets Status in “linux” package in Ubuntu: Confirmed Bug description: Seems like overlayfs and unix sockets are not playing well.
