* pkg: switch to golang native error wrappingSascha Grunert2022-07-08
| | | | | | | | | We now use the golang error wrapping format specifier `%w` instead of the deprecated github.com/pkg/errors package. [NO NEW TESTS NEEDED] Signed-off-by: Sascha Grunert <sgrunert@redhat.com>
* pkg/specgen: parse default network mode on serverPaul Holzinger2022-06-01
| | | | | | | | | | | | | | | | | | | | | When podman-remote is used we should not resolve the default network mode on the client. Defaults should be set on the server. In this case this is important because we have different defaults for root/rootless. So when the client is rootless and the server is root we must pick the root default. Note that this already worked when --network was set since we did not parsed the flag in this case. To reproduce you need --network=default. Also removed a unused function. [NO NEW TESTS NEEDED] I tested it manually but I am not sure how I can hook a test like this up in CI. The client would need to run as rootless and the server as root or the other way around.

| * replace golint with revive linterPaul Holzinger2022-04-22
| | | | | | | | | | | | | | | | | | | | | | | | golint, scopelint and interfacer are deprecated. golint is replaced by revive. This linter is better because it will also check for our error style: `error strings should not be capitalized or end with punctuation or a newline` scopelint is replaced by exportloopref (already endabled) interfacer has no replacement but I do not think this linter is important.

|/ | | | | | | | | | | From a security point of view, it would be nice to be able to map a rootless usernamespace that does not use your own UID within the container. This would add protection against a hostile process escapping the container and reading content in your homedir. Signed-off-by: Daniel J Walsh <dwalsh@redhat.com>

* support advanced network configuration via cliPaul Holzinger2021-12-14
| | | | | | | | | | | | | | | | | | | | | | | | | | Rework the --network parse logic to support multiple networks with specific network configuration settings. --network can now be set multiple times. For bridge network mode the following options have been added: - **alias=name**: Add network-scoped alias for the container. - **ip=IPv4**: Specify a static ipv4 address for this container. - **ip=IPv6**: Specify a static ipv6 address for this container. - **mac=MAC**: Specify a static mac address address for this container. - **interface_name**: Specify a name for the created network interface inside the container. So now you can set --network bridge:ip=10.88.0.10,mac=44:33:22:11:00:99 for the default bridge network as well as for network names. This is better than using --ip because we can set the ip per network without any confusion which network the ip address should be assigned to. The --ip, --mac-address and --network-alias options are still supported but --ip or --mac-address can only be set when only one network is set. This limitation already existed previously. The ability to specify a custom network interface name is new Fixes #11534 Signed-off-by: Paul Holzinger <pholzing@redhat.com>
* Add new networks format to spegecenPaul Holzinger2021-12-14

| | | | | | | | | | | | | Add the --userns flag to podman pod create and keep track of the userns setting that pod was created with so that all containers created within the pod will inherit that userns setting.

* Add the option of Rootless CNI networking by defaultMatthew Heon2021-05-26
| | | | | | | | | | | | | | | | | | | When the containers.conf field "NetNS" is set to "Bridge" and the "RootlessNetworking" field is set to "cni", Podman will now handle rootless in the same way it does root - all containers will be joined to a default CNI network, instead of exclusively using slirp4netns. If no CNI default network config is present for the user, one will be auto-generated (this also works for root, but it won't be nearly as common there since the package should already ship a config). I eventually hope to remove the "NetNS=Bridge" bit from containers.conf, but let's get something in for Brent to work with. Signed-off-by: Matthew Heon <mheon@redhat.com>

| * Ensure that --net=host/pod/container/none warn with -pMatthew Heon2020-11-04
| | | | | | | | | | | | | | | | | | | | | | | | Setting port mappings only works when CNI is configuring our network (or slirp4netns, in the rootless case). This is not the case with `--net=host`, `--net=container:`, and joining the network namespace of the pod we are part of. Instead of allowing users to do these things and then be confused why they do nothing, let's match Docker and return a warning that your port mappings will do nothing.

* | Allow multiple --network flags for podman run/createPaul Holzinger2020-11-20
|/ | | | | | | | | | | | | | We allow a container to be connected to several cni networks but only if they are listed comma sperated. This is not intuitive for users especially since the flag parsing allows multiple string flags but only would take the last value. see: spf13/pflag#72 Also get rid of the extra parsing logic for pods. The invalid options are already handled by `pkg/specgen`. A test is added to prevent a future regression. Signed-off-by: Paul Holzinger <paul.holzinger@web.de>

* allow switching of port-forward approaches in rootless/using slirp4netnsaleks-mariusz2020-07-15
| | | | | | | | | | | | | | | | | | | | | | | | | | As of podman 1.8.0, because of commit da7595a, the default approach of providing port-forwarding in rootless mode has switched (and been hard-coded) to rootlessport, for the purpose of providing super performance. The side-effect of this switch is source within the container to the port-forwarded service always appears to originate from 127.0.0.1 (see issue #5138). This commit allows a user to specify if they want to revert to the previous approach of leveraging slirp4netns add_hostfwd() api which, although not as stellar performance, restores usefulness of seeing incoming traffic origin IP addresses. The change should be transparent; when not specified, rootlessport will continue to be used, however if specifying --net slirp4netns:slirplisten the old approach will be used. Note: the above may imply the restored port-forwarding via slirp4netns is not as performant as the new rootlessport approach, however the figures shared in the original commit that introduced rootlessport are as follows: slirp4netns: 8.3 Gbps, RootlessKit: 27.3 Gbps, which are more than sufficient for many use cases where the origin of traffic is more important than limits that cannot be reached due to bottlenecks elsewhere.

* move go module to v2Valentin Rothberg2020-07-06
| | | | | | | | | | | | | | | With the advent of Podman 2.0.0 we crossed the magical barrier of go modules. While we were able to continue importing all packages inside of the project, the project could not be vendored anymore from the outside. Move the go module to new major version and change all imports to `github.com/containers/libpod/v2`. The renaming of the imports was done via `gomove` [1].

| | | | | | | | | | | | | | | | This patch allows users to specify the list of capabilities required to run their container image.

If the user or image specified capabilities that are not in the default set, the container will print an error message and will continue to run with the default capabilities.
