______________________________________________________________________________
An update that solves three vulnerabilities and has four fixes is now
available.
Description:
This is a version update for podman to version 1.4.4 (bsc#1143386).
Additional changes by SUSE on top:
o Remove fuse-overlayfs because it's (currently) an unsatisfied dependency on
SLE (bsc#1143386)
o Update libpod.conf to use correct infra_command
o Update libpod.conf to use better versioned pause container
o Update libpod.conf to use official kubic pause container
o Update libpod.conf to match latest features set: detach_keys, lock_type,
runtime_supports_json
o Add podman-remote varlink client
Version update podman to v1.4.4:
o Features
- - Podman now has greatly improved support for containers using multiple OCI
runtimes. Containers now remember if they were created with a different runtime
using --runtime and will always use that runtime - The cached and delegated
options for volume mounts are now allowed for Docker compatability (#3340) -
The podman diff command now supports the --latest flag
o Bugfixes
- - Fixed a bug where rootless Podman would attempt to use the entire root
configuration if no rootless configuration was present for the user, breaking
rootless Podman for new installations - Fixed a bug where rootless Podman's
pause process would block SIGTERM, preventing graceful system shutdown and
hanging until the system's init send SIGKILL - Fixed a bug where running Podman
as root with sudo -E would not work after running rootless Podman at least once
- - Fixed a bug where options for tmpfs volumes added with the --tmpfs flag were
being ignored - Fixed a bug where images with no layers could not properly be
displayed and removed by Podman - Fixed a bug where locks were not properly
freed on failure to create a container or pod - Fixed a bug where podman cp on
a single file would create a directory at the target and place the file in it
(#3384) - Fixed a bug where podman inspect --format '{{.Mounts}}' would print a
hexadecimal address instead of a container's mounts - Fixed a bug where
rootless Podman would not add an entry to container's /etc/hosts files for
their own hostname (#3405) - Fixed a bug where podman ps --sync would segfault
(#3411) - Fixed a bug where podman generate kube would produce an invalid ports
configuration (#3408)
o Misc
- - Updated containers/storage to v1.12.13 - Podman now performs much better on
systems with heavy I/O load - The --cgroup-manager flag to podman now shows the
correct default setting in help if the default was overridden by libpod.conf -
For backwards compatability, setting --log-driver=json-file in podman run is
now supported as an alias for --log-driver=k8s-file. This is considered
deprecated, and json-file will be moved to a new implementation in the future
([#3363](https://github.com/containers/libpo\ d/issues/3363)) - Podman's
default libpod.conf file now allows the crun OCI runtime to be used if it is
installed
Update podman to v1.4.2:
o Fixed a bug where Podman could not run containers using an older version of
Systemd as init
o Updated vendored Buildah to v1.9.0 to resolve a critical bug with
Dockerfile RUN instructions
o The error message for running podman kill on containers that are not
running has been improved
o Podman remote client can now log to a file if syslog is not available
o The podman exec command now sets its error code differently based on
whether the container does not exist, and the command in the container does
not exist
o The podman inspect command on containers now outputs Mounts JSON that
matches that of docker inspect, only including user-specified volumes and
differentiating bind mounts and named volumes
o The podman inspect command now reports the path to a container's OCI spec
with the OCIConfigPath key (only included when the container is initialized
or running)
o The podman run --mount command now supports the bind-nonrecursive option
for bind mounts
o Fixed a bug where podman play kube would fail to create containers due to
an unspecified log driver
o Fixed a bug where Podman would fail to build with musl libc
o Fixed a bug where rootless Podman using slirp4netns networking in an
environment with no nameservers on the host other than localhost would
result in nonfunctional networking
o Fixed a bug where podman import would not properly set environment
variables, discarding their values and retaining only keys
o Fixed a bug where Podman would fail to run when built with Apparmor support
but run on systems without the Apparmor kernel module loaded
o Remote Podman will now default the username it uses to log in to remote
systems to the username of the current user
o Podman now uses JSON logging with OCI runtimes that support it, allowing
for better error reporting
o Updated vendored containers/image to v2.0
o Update conmon to v0.3.0
o Support OOM Monitor under cgroup V2
o Add config binary and make target for configuring conmon with a go library
for importing values
Updated podman to version 1.4.0 (bsc#1137860) and (bsc#1135460)
o Podman checkpoint and podman restore commands can now be used to migrate
containers between Podman installations on different systems.
o The podman cp now supports pause flag.
o The remote client now supports a configuration file for pre-configuring
connections to remote Podman installations
o CVE-2019-10152: Fixed an iproper dereference of symlinks of the the podman
cp command which introduced in version 1.1.0 (bsc#1136974).
o Fixed a bug where podman commit could improperly set environment variables
that contained = characters
o Fixed a bug where rootless podman would sometimes fail to start containers
with forwarded ports
o Fixed a bug where podman version on the remote client could segfault

instead of the path of the Podman command when printing the command being
executed

o Fixed a bug where specifying a bing mount or tmpfs mount over an image
volume would cause a container to be unable to start
o Fixed a bug where podman generate kube did not work with containers with
named volumes
o Fixed a bug where rootless podman would receive permission denied errors
accessing conmon.pid
o Fixed a bug where podman cp with a folder specified as target would replace
the folder, as opposed to copying into it
o Fixed a bug where rootless Podman commands could double-unlock a lock,
causing a crash

errors when using the Kata containers runtime

libpod.conf) if not overridden in the rootless configuration
o Added fuse-overlayfs dependency to support overlay based rootless image
manipulations
o The podman cp command can now read input redirected to STDIN, and output to
STDOUT instead of a file, using - instead of an argument.
o The podman remote client now displays version information from both the
client and server in podman version
o The podman unshare command has been added, allowing easy entry into the
user namespace set up by rootless Podman (allowing the removal of files
created by rootless podman, among other things)
o Fixed a bug where Podman containers with the --rm flag were removing
created volumes when they were automatically removed
o Fixed a bug where container and pod locks were incorrectly marked as
released after a system reboot, causing errors on container and pod removal
o Fixed a bug where Podman pods could not be removed if any container in the
pod encountered an error during removal
o Fixed a bug where Podman pods run with the cgroupfs CGroup driver would
encounter a race condition during removal, potentially failing to remove
the pod CGroup

restore commands were not visible in the remote client
