Subject: [PATCH] devicemapper: remove container rootfs mountPath after umount
|
||||
|
||||
libdm currently has a fairly substantial DoS bug that makes certain
|
||||
operations fail on a libdm device if the device has active references
|
||||
through mountpoints. This is a significant problem with the advent of
|
||||
mount namespaces and MS_PRIVATE, and can cause certain --volume mounts
|
||||
to cause libdm to no longer be able to remove containers:
|
||||
|
||||
% docker run -d --name testA busybox top
|
||||
% docker run -d --name testB -v /var/lib/docker:/docker busybox top
|
||||
% docker rm -f testA
|
||||
[fails on libdm with dm_task_run errors.]
|
||||
|
||||
This also solves the problem of unprivileged users being able to DoS
|
||||
docker by using unprivileged mount namespaces to preseve mounts that
|
||||
Docker has dropped.

- Fix a regression in our SUSE secrets patches, which caused the copied files
|
||||
to not carry the correct {uid,gid} mapping when using user namespaces. This
|
||||
would not cause any bugs (SUSEConnect does the right thing anyway) but it's
|
||||
possible some programs would not treat the files correctly. This is
|
||||
tangentially related to bsc#1055676.
