* eat signal 23 in signal proxyBrent Baude2020-03-13
| | | | | | | | | | | | | | due to a change in golang-1.14 and it's changes to make go funcs with tight loops preemptive, signals are now getting "through" that never were before. From the golang-1.14 announce: Goroutines are now asynchronously preemptible. As a result, loops without function calls no longer potentially deadlock the scheduler or significantly delay garbage collection. This is supported on all platforms except windows/arm, darwin/arm, js/wasm, and plan9/*. A consequence of the implementation of preemption is that on Unix systems, including Linux and macOS systems, programs built with Go 1.14 will receive more signals than programs built with earlier releases. This means that programs that use packages like syscall or golang.org/x/sys/unix will see more slow system calls fail with EINTR errors. Those programs will have to handle those errors in some way, most likely looping to try the system call again. For more information about this see man 7 signal for Linux systems or similar documentation for other systems. Fixes #5483 Signed-off-by: Brent Baude <bbaude@redhat.com>

| * Add the rmi flag to podman-run to delete container imageBoaz Shuster2020-03-03
| | | | | | | | | | | | | | | | | | | | The --rmi flag will delete the container image after its execution unless that image is already been used by another container(s). This is useful when one wants to execute a container once and remove any resources attached to it. Signed-off-by: Boaz Shuster <boaz.shuster.github@gmail.com>

* network create should use firewall pluginBrent Baude2020-02-27
| | | | | | when creating a network, podman should add the firewall plugin to the config but not specify a backend. this will allow cni to determine whether it should use an iptables|firewalld backend. Signed-off-by: Brent Baude <bbaude@redhat.com>
* Add basic deadlock detection for container start/removeMatthew Heon2020-02-24
| | | | | | | | | | | | | | | We can easily tell if we're going to deadlock by comparing lock IDs before actually taking the lock. Add a few checks for this in common places where deadlocks might occur. This does not yet cover pod operations, where detection is more difficult (and costly) due to the number of locks being involved being higher than 2. Also, add some error wrapping on the Podman side, so we can tell people to use `system renumber` when it occurs. Signed-off-by: Matthew Heon <matthew.heon@pm.me>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add a --new flag to podman-generate-systemd to create a new container via podman-run instead of starting an existing container. Creating a new container presents the challenge to find a reverse mapping from a container to the CLI flags it can be created with. We are doing this via `(Container).Config.CreateCommand` field, which includes a copy of the process' command from procFS at creating time. This field may not be useful when the container was not created via the Podman CLI (e.g., via a Python script). Hence, we do not guarantee the correctness of the generated files.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When doing a checkpoint with --export the root file-system diff was not working as expected. Instead of getting the changes from the running container to the highest storage layer it got the changes from the highest layer to that parent's layer. For a one layer container this could mean that the complete root file-system is part of the checkpoint. With this commit this changes to use the same functionality as 'podman diff'. This actually enables to correctly diff the root file-system including tracking deleted files. This also removes the non-working helper functions from libpod/diff.go.
