libostree/sepolicy: get rid of a g_setenv() call
2022-01-12 06:51:14 -05:00
Colin Walters 998154f8ff main: Also support CLI extensions in `/usr/libexec/libostree/ext`
In fixing https://github.com/coreos/rpm-ostree/pull/3323
I felt that it was a bit ugly we're installing `/usr/bin/ostree-container`.

It's kind of an implementation detail.  We want users to use
`ostree container`.

Let's support values outside of $PATH too.

For example, this also ensures that TAB completion for `ost` expands
to `ostree ` with a space.

libostree/sepolicy: get rid of a g_setenv() call
This removes a 'g_setenv()' call, which could potentially be unsafe
in a multi-thread context.
The current libselinux codebase does not seem to check for
`LIBSELINUX_DISABLE_PCRE_PRECOMPILED`, so I think this has no effects
nowadays.
Additionally, I could not find any reference to it in libselinux
git history, so I'm not sure if it ever played any role at all.

My current understanding is that this is coming from version
incompatibilities between an older libselinux in the build environment
and a newer policy (with precompiled regexs) in the target.
But from the ML discussion I found, I think it eventually got
solved in a different way, possibly by avoiding the policy binary
caches.

libotutil: avoid leaking builder memory on error
This swaps the order of a couple of input sanity checks, in order
to fix a minor memory leak due to an early-return on the error
path.
Memory for the result is now allocated only after input has been
sanity-checked.
It fixes a static analysis warning highlighted by Coverity.

main: add support for CLI extensions via external binaries
This adds some logic to detect and dispatch unknown subcommands to
extensions available in `$PATH`. Additional commands can be
implemented by adding relevant `ostree-$verb` binaries to the system.

As an example, if a `/usr/bin/ostree-extcommand` extension is provided,
the execution of `ostree extcommand --help` will be dispatched to that
as `ostree-extcommand extcommand --help`.

Colin Walters 2c39bd88a9 repo: Change locking for summary regeneration to be shared
This is trying to address:
https://pagure.io/fedora-iot/issue/48

Basically we changed rpm-ostree to start doing a shared lock during
commit by default, but this broke because pungi is starting a process
doing a commit for each architecture, and then trying to regenerate
the summary after each one.

This patch is deleting a big comment with a rationale for why
summary regeneration should be exclusive.  Point by point:

> This makes sure the commits and deltas don't get
> deleted while generating the summary.

But prune operations require an exclusive lock, which means that
data still can't be deleted when the summary grabs a shared lock.

> It also means we can be sure refs
> won't be created/updated/deleted during the operation, without having to
> add exclusive locks to those operations which would prevent concurrent
> commits from working.

First: The status quo *has* prevented concurrent commits from working!

There is no real locking solution to this problem. What we really
need to do here is regenerate the summary after each commit *or*
when the caller decides to do it and e.g. include deltas at the same
time.

It's OK if multiple threads race to regenerate the summary;
last-one-wins behavior here is totally fine.

lib: Fix a bad call to g_file_get_child
In Glib, since commit 3a6e8bc8876e149c36b6b14c6a25a718edb581ed,
`g_file_get_child` does not accept absolute path as paramater anymore.

The broken assertion was encountered during `ostree admin deploy`
command for the checkout of subpath `etc`.

Example of error log:
```

prepare-root: make all mount operations silent
This adds a `MS_SILENT` flag to all `mount(2)` calls, reducing the

Those messages do not contain actionable details, and in the "mount

Colin Walters e6a560b407 deploy: Ignore sockets, fifos in /etc during merge
https://bugzilla.redhat.com/show_bug.cgi?id=1945274 is an issue where a privileged
kubernetes daemonset is writing a socket into `/etc`.  This makes ostree upgrades barf.

Now, they should clearly move it to `/run`.  However, one option is for us to
just ignore it instead of erroring out.  Some brief investigation shows that
e.g. `git add somesocket` is a silent no-op, which is an argument in favor of ignoring it.

This is part of `OstreeCommitModifier`, but I'm not using

It just makes more sense as a direct policy API, where it should
have been in the first place.  There's already support for
setting a policy object on a commit modifier, so that's all the
old API needs to do now.
