| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Use the new logic from c/common to create the hosts file. This will help to better allign the hosts files between buildah and podman. Also this fixes several bugs: - remove host entries when container is stopped and has a netNsCtr - add entries for containers in a pod - do not duplicate entries in the hosts file - use the correct slirp ip when an userns is used Features: - configure host.containers.internal entry in containers.conf - configure base hosts file in containers.conf Fixes #12003 Fixes #13224 Signed-off-by: Paul Holzinger <pholzing@redhat.com>

| | | | | | | | | | | | | | | | | | | | | | 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>
* | system tests: add assert(), and start using itEd Santiago2022-04-20
|/ | | | | | | | | | | | | | | | | | | | | Problem: the system test 'is()' checker was poorly thought out. For example, there is no way to check for inequality or for absence of a substring. Solution, step 1: introduce new assert(), copied almost verbatim from buildah, where it has been successful in addressing the gaps in is(). The logical next step is to search the tests for 'die' and for 'run', looking for negative assertions which we can replace with assert(). There were a lot, and in the process I found a number of ugly bugs in the tests themselves. I've taken the liberty of fixing these. Important note: at this time we have both assert() and is(). Replacing all instances of is() would be impossible to review. Signed-off-by: Ed Santiago <santiago@redhat.com>

* Make error message matching in 030-run.bats less fragileDavid Gibson2022-01-21
| | | | | | | | | | | | | | | | | | | | Amongst other things 030-run.bats checks for sensible error messages when attempting a "podman run" with a non-existent or inaccessible path. It checks for these messages, which come from the low-level runtime, in a lot of detail, including separate versions for runc and crun. This is fragile in several ways: * It's likely to fail if using a runtime other than crun or runc * It relies on detecting whether the runtime is crun vs. runc using the path, which could fail if the binary has been named something unusual * It will break if crun or runc ever alter their error message (even if it's just changing case) This replaces the checked versions with a much more accepting regex which will work for both the runc and crun messages, while still looking for the essential pieces. This isn't guaranteed to work with other runtimes, but it's much more likely to. Signed-off-by: David Gibson <david@gibson.dropbear.id.au>

| | | | | | | | | | | Some containers require certain user account(s) to exist within the container when they are run.

* 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>

| | | | | | | | | | | | | | Found by my find-obsolete-skips script. Let's see which, if any, of these skipped tests can be reenabled.

* Add --unsetenv & --unsetenv-all to remove def environment variablesDaniel J Walsh2021-11-15
| | | | | | | | | | | | | | | | Podman adds a few environment variables by default, and currently there is no way to get rid of them from your container. This option will allow you to specify which defaults you don't want. --unsetenv-all will remove all default environment variables. Default environment variables can come from podman builtin, containers.conf or from the container image.

* libpod: fix race when closing STDINPaul Holzinger2021-10-06
| | | | | | | | | | | | | | | | There is a race where `conn.Close()` was called before `conn.CloseWrite()`. In this case `CloseWrite` will fail and an useless error is printed. To fix this we move the the `CloseWrite()` call to the same goroutine to remove the race. This ensures that `CloseWrite()` is called before `Close()` and never afterwards. Also fixed podman-remote run where the STDIN was never was closed. This is causing flakes in CI testing. [NO TESTS NEEDED] Fixes #11856 Signed-off-by: Paul Holzinger <pholzing@redhat.com>
* System tests: tighten 'is' operatorEd Santiago2021-09-30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Fix day-one sloppiness: when I first wrote this framework it compared strings using 'expr', not '=', to be more forgiving of extra cruft in output. This was a bad decision. It means that warnings or additional text are ignored: is "all is ok, NOT!" "all is ok" <-- this would pass Solution: tighten up the 'is' check. Use '=' (direct compare) first. If it fails, look for wild cards ('*') or character classes ('[') in the expect string. If so, and only then, use 'expr'. And, thanks to a clever suggestion from Luap99, include '(using expr)' in the error message when we do so; this could make it easier for a developer to understand a string mismatch. This change exposes a lot of instances in which we weren't doing proper comparisons. Fix those. Thankfully, there weren't as many as I'd feared. Also, and completely unrelated, add '-T' flag to bats helper, for showing timing results. (I will open this as a separate PR if requested. I too find it offensive to jumble together unrelated commits.) Signed-off-by: Ed Santiago <santiago@redhat.com>

* System tests: add :Z to volume mountsEd Santiago2021-06-01
| | | | | | | | | | | | | | | | | | | | | | | selinux-policy-34.9-1.fc34 breaks a behavior we've relied on since (at least) January 2020: - Revert "Add permission open to files_read_inherited_tmp_files() interface" That's probably the correct thing to do, but it breaks our existing tests. Solution: add ':Z' where needed. Tested on Ed's laptop, which has the offending selinux-policy as of 2021-05-31. Tests pass root and rootless. (I mention this because tests will obviously pass in CI, which has a much older selinux-policy). Also: add a 'podman rmi' for cleanup in one test, to avoid noise in test logs.

* migrate Podman to containers/common/libimageValentin Rothberg2021-05-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Migrate the Podman code base over to `common/libimage` which replaces `libpod/image` and a lot of glue code entirely. Note that I tried to leave bread crumbs for changed tests. Miscellaneous changes: * Some errors yield different messages which required to alter some tests. * I fixed some pre-existing issues in the code. Others were marked as `//TODO`s to prevent the PR from exploding. * The `NamesHistory` of an image is returned as is from the storage. Previously, we did some filtering which I think is undesirable. Instead we should return the data as stored in the storage. * Touched handlers use the ABI interfaces where possible. * Local image resolution: previously Podman would match "foo" on "myfoo". This behaviour has been changed and Podman will now only match on repository boundaries such that "foo" would match "my/foo" but not "myfoo". I consider the old behaviour to be a bug, at the very least an exotic corner case. * Futhermore, "foo:none" does *not* resolve to a local image "foo" without tag anymore. It's a hill I am (almost) willing to die on. * `image prune` prints the IDs of pruned images. Previously, in some cases, the names were printed instead. The API clearly states ID, so we should stick to it. * Compat endpoint image removal with _force_ deletes the entire not only the specified tag. Signed-off-by: Valentin Rothberg <rothberg@redhat.com>

| | | | | | | | | | | | | | | | If you are attempting to run a container in interactive mode, and want a --tty, then there must be a terminal in use. Docker exits right away when a user specifies to use a --interactive and --TTY but the stdin is not a tty. Currently podman will pull the image and then fail much later.

* fix logic when not creating a workdirValentin Rothberg2021-02-05
| | | | | | | | | | | When resolving the workdir of a container, we may need to create unless the user set it explicitly on the command line. Otherwise, we just do a presence check. Unfortunately, there was a missing return that lead us to fall through into attempting to create and chown the workdir. That caused a regression when running on a read-only root fs.

* System test for #9096 (truncated stdout)Ed Santiago2021-02-02
| | | | | | | | | | | This actually tests conmon, not podman; but that's the whole point of system tests in the first place: if a problem exists, we want to fail loudly, no matter whose fault it is.

* workdir presence checksValentin Rothberg2021-01-26
| | | | | | | | | | | | | | | | | | A container's workdir can be specified via the CLI via `--workdir` and via an image config with the CLI having precedence. Since images have a tendency to specify workdirs without necessarily shipping the paths with the root FS, make sure that Podman creates the workdir. When specified via the CLI, do not create the path, but check for its existence and return a human-friendly error. NOTE: `crun` is performing a similar check that would yield exit code 127. With this change, however, Podman performs the check and yields exit code 126. Since this is specific to `crun`, I do not consider it to be a breaking change of Podman.

* RHEL gating tests: more journald exceptionsEd Santiago2020-12-14
| | | | | | | | | | | | | | | | | | | | Followup to #8284, due to my not having noticed #8096. RHEL gating tests are failing again due to rhbz#1895105, the one where we can't run journalctl rootless on RHEL. #8284 fixed this for some RHEL builds of older podman, but I missed #8096 which added yet another logs test. This brings us to three journalctl exceptions, which means it gets complicated because I have to refactor it all. **THIS IS NOT SUSTAINABLE**. We need some way to have a similar setup in CI, with a permission-less rootless login, so we don't add yet another logs test some day and discover, months later, that it doesn't work on RHEL and then have to go into crisis mode.
