There is currently a bug in the Xen support for Alpine where /boot/config-lts
is expected to exist but in Alpine /boot/config-VERSION-lts is the only file
available. This change copies the config to /boot/config-lts to fix the build.
The resolv.conf that the stage1 os script generates is fine for actual use,
but our GitHub workflows now uses the Step Security hardened runner action.
This action replaces the nameserver so that all lookups go through that,
but because the chroot calls apk add, it needs to contact the internet.
On the GitHub workflows, the OS build currently fails since the hardened
runner cannot access other nameservers.
Now that we have the kernel build infrastructure at https://github.com/edera-dev/kernels
it makes sense to drop building the kernel and download the kernel images directly.
This change introduces a ./hack/kernel/fetch.sh script which is backed by crates/build
We utilize the OCI infrastructure itself to download the kernel image. The DEV guide
has been updated to include calling the fetch script, and the OS builder now uses this
method instead. Due to the lack of need for the kernel build infra to exist here now,
it has also been removed. This should significantly speed up full builds.
This change will also enable us to turn on os build workflows for all PRs. We should
likely make the OS status checks required once this is merged.
We have a need to ensure great security while also ensuring that dependabot
does not constantly provide multiple PRs. After all, when something becomes
too time consuming it risks not being handled with care. With grouped updates,
version bumps will get grouped together, but security updates will still be
indvidualized. This makes it safer for us to enable grouped dependency updates.
Previously, krata runtime allowed a single permit when performing operations.
This was necessary because the only IP allocation storage was xenstore, and
the commit of xenstore data happens after allocation. This commit introduces
IpVendor, a service which vends IPv4 and IPv6 addresses to guests using a
linear address strategy within an IP network space. The IpVendor table is
initialized from xenstore, and from there on out, the in-memory table
is the source of truth. This implementation is not perfect, but it will allow
us to lift the single permit limit, allowing guests to start concurrently.

Implement IDM snooping, a new feature that lets you snoop on messages between guests and the host. The feature exposes the IDM packets send and receives
to the API, allowing kratactl to now listen for messages and feed them to a user for debugging purposes.

* feat: daemon idm now uses IdmClient
* fix: implement channel destruction propagation
