* Properly handle podman run --pull commandDaniel J Walsh2020-09-27
| | | | | | | | | | | | | | | | | | Currently the --pull missing|always|never is ignored This PR implements this for local API. For remote we need to default to pullpolicy specified in the containers.conf file. Also fixed an issue when images were matching other images names based on prefix, causing images to always be pulled. I had named an image myfedora and when ever I pulled fedora, the system thought that it there were two images named fedora since it was checking for the name fedora as well as the prefix fedora. I changed it to check for fedora and the prefix /fedora, to prefent failures like I had. Signed-off-by: Daniel J Walsh <dwalsh@redhat.com>
* HTTP Attach: Wait until both STDIN and STDOUT finishMatthew Heon2020-09-24
| | | | | | | | | | | | | | | In the old code, there was a chance that we could return when only one of STDIN or STDOUT had finished - this could lead to us dropping either input to the container, or output from it, in the case that one stream terminated early. To resolve this, use separate channels to return STDOUT and STDIN errors, and track which ones have returned cleanly to ensure that we need bith in order to return from the HTTP attach function and pass control back to the HTTP handler (which would assume we exited cleanly and close the client's attach connection).

| * Preserve groups in exec sessions in ctrs with --userMatthew Heon2020-09-18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Podman wants to guarantee that exec sessions retain the groups of the container they are started in, unless explicitly overridden by the user. This guarantee was broken for containers where the `--user` flag was specified; this patch resolves that. Somewhere in the Exec rewrite for APIv2, I changed the location where the container's User is passed into the exec session (similar to groups, we also want to preserve user unless overridden). The lower-level Exec APIs already handled setting user and group appropriately if not specified when the exec session was created, but I added duplicate code to handle this higher in the stack - and that code only handled setting user, not supplemental groups, breaking support in that specific case. Two things conspired to make this one hard to track down: first, things were only broken if the container explicitly set a user; otherwise, the container user would still appear to be unset to the lower-level code, which would properly set supplemental groups (this tricked our existing test into passing). Also, the `crun` OCI runtime will add the groups without prompting, which further masked the problem there. I debated making `runc` do the same, but in the end it's better to fix this in Podman - it's better to be explicit about what we want done so we will work with all OCI runtimes.

* | image list: return all associated namesValentin Rothberg2020-09-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Always return all associated names / repo tags of an image and fix a bug with malformed repo tags. Previously, Podman returned all names only with `--all` but this flag only instructs to list intermediate images and should not alter associated names. With `--all` Podman queried the repo tags of an image which splits all *tagged* names into repository and tag which is then reassembled to eventually be parsed again in the frontend. Lot's of redundant CPU heat and buggy as the reassembly didn't consider digests which ultimately broke parsing in the frontend. Fixes: #7651 Signed-off-by: Valentin Rothberg <rothberg@redhat.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Basically, we want to force the application in the container to (iff the container was made with a terminal) redraw said terminal immediately after an attach completes, so the fresh Attach session will be able to see what's going on (e.g. will have a shell prompt). Our current attach functions are unfortunately geared more towards `podman run` than `podman attach` and will start forwarding resize events *immediately* instead of waiting until the attach session is alive (much safer for short-lived `podman run` sessions, but broken for the `podman attach` case). To avoid a major rewrite, let's just manually send a SIGWINCH after attach succeeds to force a redraw. Fixes #6253 Signed-off-by: Matthew Heon <matthew.heon@pm.me>

We did not, however, add entries to the group file, and this created problems - our passwd entries included the group the user is in, but said group might not exist. The solution is to mirror our logic for /etc/passwd modifications to also edit /etc/group in the container. Unfortunately, this is not a catch-all solution. Our logic here is only advanced enough to *add* to the group file - so if the group already exists but we add a user not a part of it, we will not modify that existing entry, and things remain inconsistent. We can look into adding this later if we absolutely need to, but it would involve adding significant complexity to this already massively complicated function. While we're here, address an edge case where Podman could add a user or group whose UID overlapped with an existing user or group. Also, let's make users able to log into users we added. Instead of generating user entries with an 'x' in the password field, indicating they have an entry in /etc/shadow, generate a '*' indicating the user has no password but can be logged into by other means e.g. ssh key, su.
