[Test case] See original bug report. [Fix] While we don't have a final fix the solution for now is to revert the following commits: UBUNTU: SAUCE: overlayfs: fix shitfs special-casing UBUNTU: SAUCE: overlayfs: use shiftfs hacks only with shiftfs as underlay [Regression potential] Low. Reverting these two commits will introduce back the issue reported on bug 1857257, but will fix the other use cases which was broken by the latest release. Original bug report. ----------------------------------- Tested kernels: Focal 5.4.0-31.35 Eoan 5.3.0-53.47 To reproduce: 1) Spin up a cloud image 2) snap install docker 3) auth_folder=/var/snap/docker/common/auth 4) mkdir -p $auth_folder 5) docker run --entrypoint htpasswd registry:2 -Bbn user passwd > $auth_folder/htpasswd 6) docker run -d -p 5000:5000 --restart=always --name registry \ -v $auth_folder:/auth \ -e "REGISTRY_AUTH=htpasswd" \ -e "REGISTRY_AUTH_HTPASSWD_REALM=Registry Realm" \ -e REGISTRY_AUTH_HTPASSWD_PATH=/auth/htpasswd \ registry:2 On a good kernel 'docker ps' shows something like: # docker ps CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES a346b65b4509 registry:2 "/entrypoint.sh /etc…" 14 seconds ago Up 12 seconds 0.0.0.0:5000->5000/tcp registry On a bad kernel: docker ps CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 0322374f1b1d registry:2 "/entrypoint.sh /etc…" 5 seconds ago Restarting (2) 1 second ago registry Note status 'Restarting' on the bad kernel.
