* podman ssh work, using new c/common interfaceCharlie Doern2022-08-09
| | | | | | | | | | | | | | | | | | | implement new ssh interface into podman this completely redesigns the entire functionality of podman image scp, podman system connection add, and podman --remote. All references to golang.org/x/crypto/ssh have been moved to common as have native ssh/scp execs and the new usage of the sftp package. this PR adds a global flag, --ssh to podman which has two valid inputs `golang` and `native` where golang is the default. Users should not notice any difference in their everyday workflows if they continue using the golang option. UNLESS they have been using an improperly verified ssh key, this will now fail. This is because podman was incorrectly using the ssh callback method to IGNORE the ssh known hosts file which is very insecure and golang tells you not yo use this in production. The native paths allows for immense flexibility, with a new containers.conf field `SSH_CONFIG` that specifies a specific ssh config file to be used in all operations. Else the users ~/.ssh/config file will be used. podman --remote currently only uses the golang path, given its deep interconnection with dialing multiple clients and urls. My goal after this PR is to go back and abstract the idea of podman --remote from golang's dialed clients, as it should not be so intrinsically connected. Overall, this is a v1 of a long process of offering native ssh, and one that covers some good ground with podman system connection add and podman image scp.

* podman image scp remote support & podman image scp taggingcdoern2022-06-28
| | | | | | | | | | | | | | | | | | | add support for podman-remote image scp as well as direct access via the API. This entailed a full rework of the layering of image scp functions as well as the usual API plugging and type creation also, implemented podman image scp tagging. which makes the syntax much more readable and allows users t tag the new image they are loading to the local/remote machine: allow users to pass a "new name" for the image they are transferring `podman tag` as implemented creates a new image im `image list` when tagging, so this does the same meaning that when transferring images with tags, podman on the remote machine/user will load two images ex: `podman image scp computer1::alpine computer2::foobar` creates alpine:latest and localhost/foobar on the remote host implementing tags means removal of the flexible syntax. In the currently released podman image scp, the user can either specify `podman image scp source::img dest::` or `podman image scp dest:: source::img`. However, with tags this task becomes really hard to check which is the image (src) and which is the new tag (dst). Removal of that streamlines the arg parsing process Signed-off-by: Charlie Doern <cdoern@redhat.com>
* enable gocritic linterPaul Holzinger2022-04-26
| | | | | | | | | | | | | | | | | | | | | | The linter ensures a common code style. - use switch/case instead of else if - use if instead of switch/case for single case statement - add space between comment and text - detect the use of defer with os.Exit() - use short form var += "..." instead of var = var + "..." - detect problems with append() ``` newSlice := append(orgSlice, val) ``` This could lead to nasty bugs because the orgSlice will be changed in place if it has enough capacity too hold the new elements. Thus we newSlice might not be a copy. Of course most of the changes are just cosmetic and do not cause any logic errors but I think it is a good idea to enforce a common style. This should help maintainability. Signed-off-by: Paul Holzinger <pholzing@redhat.com>
* Remove error stutterDaniel J Walsh2022-03-25
| | | | | | | | | | | | | | | | | When podman gets an error it prints out "Error: " before printing the error string. If the error message starts with error, we end up with Error: error ... This PR Removes all of these stutters. logrus.Error() also prints out that this is an error, so no need for the error stutter. [NO NEW TESTS NEEDED] Signed-off-by: Daniel J Walsh <dwalsh@redhat.com>

|/ | | | | | | | | machinectl does not propogate error messages and adds extra lines in the output, exec.Cmd is able to clear the env besides PATH and TERM, and use the given UID and GID to execute the command properly. machinectl is still used to create a user session.

* podman image scp never enter podman user NScdoern2021-12-23
| | | | | | | | | | | Podman image scp should never enter the Podman UserNS unless it needs to. This allows for a sudo exec.Command to transfer images to and from rootful storage. If this command is run using sudo, the simple sudo podman save/load does not work, machinectl/su is necessary here. This modification allows for both rootful and rootless transfers, and an overall change of scp to be more of a wrapper function for different load and save calls as well as the ssh component Signed-off-by: cdoern <cdoern@redhat.com>
