This adds a new concept for handling paths. At appropriate places, if a
path such as /foo/bar/baz.v/ is specified, we'll
automatically enumerate all entries in /foo/bar/baz.v/baz* and then
do a version sort and pick the newest file.
A slightly more complex syntax is available, too:
/foo/bar/baz.v/quux___waldo
if that's used, then we'll look for all files matching
/foo/bar/baz.v/quux*waldo, and split out the middle, and version sort
it, and pick the nwest.
The ___ wildcard indicates both a version string, and if needed an
architecture ID, in case per-arch entries shall be supported.
This is a very simple way to maintain versioned resources in a dir, and
make systemd's components automatically pick the newest. Example:
/srv/myimages.v/foobar_1.32.65_x86-64.raw
/srv/myimages.v/foobar_1.33.45_x86-64.raw
/srv/myimages.v/foobar_1.31.5_x86-64.raw
/srv/myimages.v/foobar_1.31.5_arm64.raw
If now nspawn is invoked like this:
systemd-nspawn --image=/srv/myimages.v/foobar___.raw
Then it will automatically pick
/srv/myimages.v/foobar_1.33.45_x86-64.raw as the version to boot on
x86-64, and /srv/myimages.v/foobar_1.31.5_arm64.raw on arm64.
This commit only adds the basic implementation for picking files from a
dir, but no hook-up anywhere.
Let's get networkd onto Varlink. This only adds the most basic of
operations.
I'd love to see networkd do Varlink for all its basic operations so that
networkctl can use that, and work correctly before D-Bus is up. Right
now, many of networkctls calls simply don't work before D-Bus, and I'd
like to see that improved.
Let's add a new "plymouth-util.c" module with helpers for talking to
plymouth. We so far had three places for this, let's unify the code
doing this a bit.
Let's split out the logic that actually generates the word to measure to
PCRs into a new helper file pcrextend-util.[ch].
This we can later reuse to calculate PCR measurement predictions ahead
of time.
This is primarily supposed to be a 1st step with varlinkifying our
various command line tools, and excercise in how this might look like
across our codebase one day. However, at AllSystemsGo! 2023 it was
requested that we provide an API to do a PCR measurement along with a
matching event log record, and this provides that.
The official org.varlink.service interface definition, as per:
https://varlink.org/Service
And the io.systemd service where we carry some super generic errors our
Varlink implementation generates.
Build targets should have a link dependency on the version scripts they
use. This also uses absolute paths in anticipation for meson 1.3
needlessly deprecating file to string conversions.
By making this a disabler dependency, we can slightly simplify the code
and it als fixes the build for -Dfdisk=disabled as we failed to create a
fallback empty libshared_fdisk variable.
When the credential dir is backed by an fs that supports ACLs we must be
more careful with adjusting the 'x' bit of the directory, as any chmod()
call on the dir will reset the mask entry of the ACL entirely which we
don't want. Hence, do a manual set of ACL changes, that only add/drop
the 'x' bit but otherwise leave the ACL as it is.
This matters if we use tmpfs rather than ramfs to store credentials.
The file long ceased to be exclusively about configuration of the sleep
operation. It contains many many calls for other purposes, hence give it
a more generic name.
This was requested in review:
https://github.com/systemd/systemd/pull/27846#discussion_r1210383265
I kept this as separate commit because the change would impact both of
the previous commits and splitting it up seems like unnecessary work.
The result is unchanged.
v2:
- use universal_newlines=True to keep compat with Python 3.6 on C8S.
No code change, just some splitting out of the relevant code from
udev-util.[ch].
This makes sense on its own, but is also prepartion to move the code
that checks for low battery state into battery-util.[ch], too.
The entries are sorted by speed. Some fields are left empty when there is no
clear value to use. The table is much longer now, but I think it's better to
document the allowed values, even if some are not terribly useful.
Fixes#26256.
We updated this table manually, but the kernel adds new modes periodically
and we forget to do that. So let that happen automatically whenever we import
new kernel headers.

Effectively, this adds:
[ETHTOOL_LINK_MODE_10baseT1L_Full_BIT] = "10baset1l-full",
[ETHTOOL_LINK_MODE_800000baseCR8_Full_BIT] = "800000basecr8-full",
[ETHTOOL_LINK_MODE_800000baseKR8_Full_BIT] = "800000basekr8-full",
[ETHTOOL_LINK_MODE_800000baseDR8_Full_BIT] = "800000basedr8-full",
[ETHTOOL_LINK_MODE_800000baseDR8_2_Full_BIT] = "800000basedr8-2-full",
[ETHTOOL_LINK_MODE_800000baseSR8_Full_BIT] = "800000basesr8-full",
[ETHTOOL_LINK_MODE_800000baseVR8_Full_BIT] = "800000basevr8-full",
N_ADVERTISE needed to be increased because we need more bits.
crypsetup-fido2 always depended on both libfido2 and libcryptsetup, but
0a8e026e82 forgot to make the then
implicit dependency on libcryptsetup explicit when moving it from
cryptsetup/ to shared/. This breaks builds when libfido2 is autodetected
but the system is missing libcryptsetup.
Introduce an explicit check for HAVE_LIBCRYPTSETUP such that
cryptsetup-fido2 is only built when both libraries are available.
Fixes#27374.
This makes the bpf LSM check generic, so that we can use it elsewhere.
it also drops the caching inside it, given that bpf-lsm code in PID1
will cache it a second time a stack frame further up when it checks for
various other bpf functionality.
No functional change, just preparation for later commits.
These can be used in kernel-install later.
Note, unlike the our usual coding style, the arguments for
boot_entry_token_ensure() and parse_boot_entry_token_type() are
referenced, updated, and may freed, hence, always pass initialized
values. That's why they are not named as 'ret_xyz'.
