fa02d04ee9 resolved: update condition for caching full packets
Previously a full packet was cached only if the CD bit was set, but this
no longer corresponds to the cases where bypass is enabled.

Update the cache to retain a full packet in the cases where it might
actually be useful.

36074e0149 resolved: enable CD bit without DO set
This is useful for a validating resolver to indicate to a non-validating
resolver when checking was disabled for the query. This matches the
behavior of the major public resovlers in response to queries with CD bu
tnot DO set.

008f23b7c5 resolved: authenticate bypass queries
Following 13e15dae9f, resolved does not forward the AD bit for bypass
queries, but resolved also didn't do it's own validation, making these
replies appear to never be authentic. We should enable validation for
bypass queries.

Let's disable our own validation when processing a +cd query, and also
ensure that it skips the cache so that we don't accidentally fail to
return inauthentic replies from upstream.

Previously, when we had a bypass transaction without cd, a cached,
authenticated, reply with cd could be served, leaving the cd bit
erroneously set in the reply. Only reply with a CD bit if the client
requested it.

Fixes: 13e15dae9f (resolved: clear the AD bit for bypass packets)

88bbf187a9 TEST-55-OOMD: workaround for kernel regression in 6.12-rcX
This ignore failures when running on kernel-6.12-rcX, which has a
regression in the kernel scheduler that breaks PSI.

From https://github.com/systemd/systemd/issues/32730#issuecomment-2415312260
> There is a known scheduler bug in 6.12 that breaks psi. It leaks
> "running tasks" counts, which matches your symptoms of seeing partial
> pressure only.
>
> Do you see "inconsistent task state" warnings in dmesg | grep psi?
>
> A fix is queued in the scheduler tree, should be sent to Linus shortly:
> https://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git/commit/?id=c6508124193d42bbc3224571eb75bfa4c1821fbb

sysupdate: Introduce optional features
Optional features allow distros to define sets of transfers that can
be enabled or disabled by the system administrator. This is useful for
situations where a distro may want to ship some resources version-locked
to the core OS, but many people have no need for the resource, such as:
development tools/compilers, drivers for specialized hardware, language
packs, etc

We also rename sysupdate.d/*.conf -> sysupdate.d/*.transfer, because
now there are more than one type of definition in sysupdate.d/. For
backwards compat, we still load *.conf files as long as no *.transfer
files are found and the *.conf files don't try to declare themselves
as part of any features

2f6fe4e113 test: customize /etc/os-release instead of /usr/lib/os-release
As per spec image builders can create a local /etc/os-release
with per-image IDs, so modify that one instead of the original
one in /usr/lib. For example we do this when we build debian
unstable images in mkosi.

fafc3c2d5c GREEDY_REALLOC_APPEND: Make more type safe
Previously, GREEDY_REALLOC_APPEND would compile perfectly fine and cause
subtle memory corruption if the caller messes up the type they're passing
in (i.e. by forgetting to pass-by-reference when appending a Type* to an
array of Type*). Now this will lead to compilation failure

63d4c4271c cgroup: Add ManagedOOMMemoryPressureDurationSec= override setting for units
This will allow units (scopes/slices/services) to override the default
systemd-oomd setting DefaultMemoryPressureDurationSec=.

The semantics of ManagedOOMMemoryPressureDurationSec= are:
- If >= 1 second, overrides DefaultMemoryPressureDurationSec= from oomd.conf
- If is empty, uses DefaultMemoryPressureDurationSec= from oomd.conf
- Ignored if ManagedOOMMemoryPressure= is not "kill"
- Disallowed if < 1 second

Note the corresponding dbus property is DefaultMemoryPressureDurationUSec
which is in microseconds. This is consistent with other time-based
dbus properties.

cc2030f928 pid1: add env var to override default mount rate limit interval
Similar to 24a4542c. 24a4542c can only be set 1 in 1s at most,
sometimes we may need to set to something else(such as 1 in 2s).
So it's best to let the user decide.

This also allows users to solve #34690.

ddbddebe0c sysext: Deal with nested mounts properly
Nested mounts should be carried over from host to overlayfs to overlayfs
(and back to host if unmerged). Otherwise you run into hard to debug
issues where merging extensions means you can't unmount those nested mounts
anymore as they are hidden by the overlayfs mount.

To fix this, before unmerging any previous extensions, let's move the nested
mounts from the hierarchy to the workspace, then set up the new hierachy, and
finally, just before moving the hierarchy into place, move the nested mounts
back into place.

Because there might be multiple nested mounts that consists of one or more
mounts stacked on top of each other, we make sure to move all stacked mounts
properly to the overlayfs. The kernel doesn't really provide a nice way to do
this, so we create a stack, pop off each mount onto the stack and then pop from
the stack again to the destination to re-establish the stacked mounts in the same
order in the destination.
