TPM 1.2 is obsolete, and doesn't really provide much security guarantees
given it's build around SHA1 which is not up to today's standards.
The rest of systemd's TPM codebase never supported TPM 1.2 hence let's
drop this partial support in sd-stub too. It has created problems after
all (sd-stub reported the measuements and userspace assumed these were
for TPM2), without bringing any benefits (given that the measurements we
make are not consumed by us anyway, unlike those for TPM 2.0)
let's cut off this old support.
This reverts commit 5e8ff010a1.
This broke all the URLs, we can't have that. (And actually, we probably don't
_want_ to make the change either. It's nicer to have all the pages in one
directory, so one doesn't have to figure out to which collection the page
belongs.)
Add persistent symlinks for media controller ("mediaX") devices, based
on their ID_PATH udev properties.
For example, if the uvcvideo driver creates /dev/media0, a persistent
name may be:
/dev/media/by-path/pci-0000:04:00.3-usb-0:1:1.0-media-controller
Persistent links are a handy tool to make scripts self-documenting
during development or in tests, as well as less error prone in case of
devices changing enumeration order. For media controllers, one can
alternatively scan through all of them and look for a matching bus_info
in their struct media_device_info, but the links are much handier when
drafting something by hand.
A similar pattern already exists for Video4Linux /dev/videoX devices,
see 60-persistent-v4l.rules for those.
This deprecates IPForward= setting, which unconditionally controled
the global setting, even though it is a setting in .network file.
Instead, this introduces new IPv4Forwarding= and IPv6Forwarding=
settings both in .network and networkd.conf.
If these settings are specified in a .network file, then the
per-interface forwarding setting will be configured.
If specified in networkd.conf, then the global IP forwarding setting will
be configured.
Closes#30648.
The flag takes "auto" or "import" or a boolean value.
"auto" causes systemd-sysext to make a decision about mutability of the merged
hierarchy based on existence of the upper directory in
`/var/lib/extensions.mutable/${hierarchy}`.
"import" causes the existing upper dir to be actually used as another lower
dir, which results in read-only merged hierarchy.
True value makes systemd-sysext to create the upper dir if it's missing and to
make the merged hierarchy mutable.
False value makes systemd-sysext to ignore upper dir completely, and create a
read-only merged hierarchy.
The default is false value.
systemd-sysext will check if /var/lib/extensions.mutable/${hierarchy} exists
and use it as an overlayfs upperdir for storing writes. This allows having
mutable hierarchy after merging the extension images.
The implementation is following a proposed update to the Extension Images
specification at https://github.com/uapi-group/specifications/pull/78.
Divide the merge_hierarchy function into code that:
- determines the lower directories for overlayfs
- determination of lower directories was further split into top, middle and
bottom directories:
- bottom - possibly the hierarchy itself
- middle - hierarchies from extensions
- top - metadata directory
- mounts the overlayfs using determined directories
- writes information to the metadata directory
- makes the merged hierarchy read-only
The follow-up commit will refactor some code in systemd-sysext, so add some
tests to make sure that things didn't break. The tests will be later extended
with cases for new features added.
I have a large initrd (built with mkosi-initrd) and the test-ukify takes 30 s.
Let's use the usual approach of skipping the slowests tests.
(pytest has marks, and it would be nicer to mark tests with pytest.mark.slow,
and then use "-m 'not slow'" in the meson test invocation. But markers must be
pre-registered, otherwise pytest emits a warning. There are a few ways to
register markers, but they all require "project configuration", but because of
how we invoke pytest, this is hard to do. So let's just use an environment
variable.)
Allow to set the broadcast queueing threshold
on macvlan devices. This controls which multicast packets will be
processed in a workqueue instead of inline.
