* golangci-lint: enable nolintlintPaul Holzinger2022-06-14
| | | | | | | | | | The nolintlint linter does not deny the use of `//nolint` Instead it allows us to enforce a common nolint style: - force that a linter name must be specified - do not add a space between `//` and `nolint` - make sure nolint is only used when there is actually a problem Signed-off-by: Paul Holzinger <pholzing@redhat.com>
* test: use `T.TempDir` to create temporary test directoryEng Zer Jun2022-05-05
| | | | | | | | | | | | | | | | | | | This commit replaces `ioutil.TempDir` with `t.TempDir` in tests. The directory created by `t.TempDir` is automatically removed when the test and all its subtests complete. Prior to this commit, temporary directory created using `ioutil.TempDir` needs to be removed manually by calling `os.RemoveAll`, which is omitted in some tests. The error handling boilerplate e.g. defer func() { if err := os.RemoveAll(dir); err != nil { t.Fatal(err) } } is also tedious, but `t.TempDir` handles this for us nicely.

* 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>

* Improved hooks monitoringsamc242019-07-25
| | | | | | | | | | | | | ...to work for specific edge cases with a simpler solution. Re-reads hooks directories after any changes are detected by the watchers. Added monitoring test for adding a different invalid hook to primary directory. Some issues with prior code: - ReadDir would stop when it encounters an invalid hook, rather than registering an error but continuing to read the valid hook. - Wouldn’t account for Rename and Chmod events. - After doing a mv of the hooks file instead of rm, it would still think the hooks file is in the directory, but it has been moved to another location. - If a hook file was renamed, it would register the renamed file as a separate hook and not delete the original, so it would then execute the hook twice - once for the renamed file, and once for the original name which it did not delete.

* Potentially breaking: Make hooks sort order locale-independentMiloslav Trmač2019-04-09
| | | | | | | | | | | | | | | | | | | Don't sort OCI hooks using the locale collation order; it does not make sense for the same system-wide directory to be interpreted differently depending on the user's LC_COLLATE setting, and the language-specific collation order can even change over time. Besides, the current collation order determination code has never worked with the most common LC_COLLATE values like en_US.UTF-8. Ideally, we would like to just order based on Unicode code points to be reliably stable, but the existing implementation is case-insensitive, so we are forced to rely on the unicode case mapping tables at least. (This gives up on canonicalization and width-insensitivity, potentially breaking users who rely on these previously documented properties.) Signed-off-by: Miloslav Trmač <mitr@redhat.com>
* pkg/hooks/exec: Include failed command in hook errorsW. Trevor King2019-01-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For example: $ cat /etc/containers/oci/hooks.d/test.json { "version": "1.0.0", "hook": { "path": "/bin/sh", "args": ["sh", "-c", "echo 'oh, noes!' >&2; exit 1"] }, "when": { "always": true }, "stages": ["precreate"] } $ podman run --rm docker.io/library/alpine echo 'successful container' error setting up OCI Hooks: executing [sh -c echo 'oh, noes!' >&2; exit 1]: exit status 1 The rendered command isn't in in the right syntax for copy/pasting into a shell, but it should be enough for the user to be able to locate the failing hook. They'll need to know their hook directories, but with the previous commits requiring explicit hook directories it's more likely that the caller is aware of them. And if they run at a debug level, they can see the lookups in the logs: $ podman --log-level=debug --hooks-dir=/etc/containers/oci/hooks.d run --rm docker.io/library/alpine echo 'successful container' 2>&1 | grep -i hook time="2018-12-02T22:15:16-08:00" level=debug msg="reading hooks from /etc/containers/oci/hooks.d" time="2018-12-02T22:15:16-08:00" level=debug msg="added hook /etc/containers/oci/hooks.d/test.json" time="2018-12-02T22:15:16-08:00" level=debug msg="hook test.json matched; adding to stages [precreate]" time="2018-12-02T22:15:16-08:00" level=warning msg="container 3695c6ba0cc961918bd3e4a769c52bd08b82afea5cd79e9749e9c7a63b5e7100: precreate hook: executing [sh -c echo 'oh, noes!' >&2; exit 1]: exit status 1" time="2018-12-02T22:15:16-08:00" level=error msg="error setting up OCI Hooks: executing [sh -c echo 'oh, noes!' >&2; exit 1]: exit status 1" Signed-off-by: W.

* hooks: Add pre-create hooks for runtime-config manipulationW. Trevor King2019-01-08
| | | | | | | | | | | | | | | | | | | | | | | There's been a lot of discussion over in [1] about how to support the NVIDIA folks and others who want to be able to create devices (possibly after having loaded kernel modules) and bind userspace libraries into the container. Currently that's happening in the middle of runc's create-time mount handling before the container pivots to its new root directory with runc's incorrectly-timed prestart hook trigger [2]. With this commit, we extend hooks with a 'precreate' stage to allow trusted parties to manipulate the config JSON before calling the runtime's 'create'. I'm recycling the existing Hook schema from pkg/hooks for this, because we'll want Timeout for reliability and When to avoid the expense of fork/exec when a given hook does not need to make config changes [3].

* pkg/hooks/exec: Add a new package for local hook executionW. Trevor King2018-05-31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This wraps os/exec to: * Clear the environment when the hook doesn't set 'env'. The runtime spec has [1]: > * env (array of strings, OPTIONAL) with the same semantics as IEEE > Std 1003.1-2008's environ. And running execle or similar with NULL env results in an empty environment: $ cat test.c #include <unistd.h> int main() { return execle("/usr/bin/env", "env", NULL, NULL); } $ cc -o test test.c $ ./test ...no output... Go's Cmd.Env, on the other hand, has [2]: > If Env is nil, the new process uses the current process's environment. This commit works around that by setting []string{} in those cases to avoid leaking the runtime environment into the hooks. * Roll the 'timeout' value (if set) into the passed context. There's no need for two separate ways to cancel hook execution. * Add a configurable timeout on abandoning a post-kill wait. The waiting goroutine will continue and eventually reap the process, but this avoids blocking the Run() call when that takes inordinately long (for example, if a GPU cleanup hook is stuck in I/O sleep [3]). The 'env' output format is specified in POSIX [4].

| | | | | | | | | | | | | | | | | | | | | | | The process property is optional [1], which this package already handled appropriately, although I've added a new test here to guard against regressions. The process.args entry is required when process is set [2], and it's also required to contain at least one entry [3].

* hooks: Fix monitoring of multiple directoriesW. Trevor King2018-05-17
| | | | | | | | | | | | | | | | | | | | | | | | | | This isn't an issue with podman, which will only ever use one directory. But CRI-O generally uses two directories, and we want to make sure that changes to the fallback directory are not clobbering hooks configured in the override directory. More background in [1]. I've split the handling into a single-directory block and a multiple-directory block so we don't waste time polling the filesystem for single-directory removals. I'm using the single-directory block for the the zero-directory case as well. Managers with zero directories should not be receiving fsnotify events, so I don't think it really matters which block handles them. If we want to handle this case robustly (because we're concerned about something in the hook package adjusted the private .directories property on the fly?), then we'll probably want to add an explicit zero-directory block in future work.

* hooks/docs: Add oci-hooks.5 and per-package man page buildingW. Trevor King2018-05-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This allows us to reference the hooks docs from podman(1) in a way that will survive system installation. The downside is that the GitHub rendered pages become less usable, now that we can no longer embed links as freely as we could before. I've followed the "Sections within a manual page" suggestions from [1]. locale(7) is [2], which is Linux-specific. Even section numbering is platform-dependent [3], so it's unlikely that these external man references are particularly portable. Platform packagers can adjust our local references to match their target system, but that leaves the GitHub rendering in an awkward place. For now, I think a Linux-centric GitHub rendering without clickable links may be the best we can do without moving away from go-md2man. As far as I can tell, there's not a nice way to get go-md2man to wrap the links in SEE ALSO without sometimes hyphenating a URL (which makes it harder for man-page readers to copy/paste those links into their browser). I've also fixed some "extention" -> "extension" typos.
