We have /usr/lib/systemd/libsystemd-{shared,core}-nnn.so. With this
path the 'nnn' part can be changed to something different. The idea
is that during a package build this will be set to the package version.
This way during in-place upgrades with the same major version both
the new and old libraries can cooexit. This should fix the issue
when systemd programs are called during package upgrades and fail
to exec because the expect different symbols in the library they
are linked to.
This should fix https://bugzilla.redhat.com/show_bug.cgi?id=1906010.
The scheme is very similar to libsystemd-shared.so: instead of building a
static library, we build a shared library from the same objects and link the
two users to it. Both systemd and systemd-analyze consist mostly of the fairly
big code in libcore, so we save a bit on the installation:
(-0g, no strip)
-rwxr-xr-x 5238864 Dec 14 12:52 /var/tmp/inst1/usr/lib/systemd/systemd
-rwxr-xr-x 5399600 Dec 14 12:52 /var/tmp/inst1/usr/bin/systemd-analyze
-rwxr-xr-x 244912 Dec 14 13:17 /var/tmp/inst2/usr/lib/systemd/systemd
-rwxr-xr-x 461224 Dec 14 13:17 /var/tmp/inst2/usr/bin/systemd-analyze
-rwxr-xr-x 5271568 Dec 14 13:17 /var/tmp/inst2/usr/lib/systemd/libsystemd-core-250.so
(-0g, strip)
-rwxr-xr-x 2522080 Dec 14 13:19 /var/tmp/inst1/usr/lib/systemd/systemd
-rwxr-xr-x 2604160 Dec 14 13:19 /var/tmp/inst1/usr/bin/systemd-analyze
-rwxr-xr-x 113304 Dec 14 13:19 /var/tmp/inst2/usr/lib/systemd/systemd
-rwxr-xr-x 207656 Dec 14 13:19 /var/tmp/inst2/usr/bin/systemd-analyze
-rwxr-xr-x 2648520 Dec 14 13:19 /var/tmp/inst2/usr/lib/systemd/libsystemd-core-250.so
So for systemd itself we grow a bit (2522080 → 2648520+113304=2761824), but
overall we save. The most is saved on all the test files that link to libcore,
if they are installed, because there's 15 of them:
$ du -s /var/tmp/inst?
220096 /var/tmp/inst1
122960 /var/tmp/inst2
I also considered making systemd-analyze a symlink to /usr/lib/systemd/systemd
and turning systemd into a multicall binary. We did something like this with
udevd and udevadm. But that solution doesn't fit well in this case.
systemd-analyze has a bunch of functionality that is not used in systemd,
so the systemd binary would need to grow quite a bit. And we're likely to
add new types of verification or introspection features in analyze, and this
baggage would only grow. In addition, there are the test binaries which also
benefit from this.
This patch changes busctl capture to generate pcapng format
instead of the legacy pcap format files. It includes basic
meta-data in the file and still uses microsecond time
resolution. In future, more things can be added such as
high resolution timestams, statistics, etc.
PCAP Next Generation capture file format is what tshark uses
and is in process of being standardized in IETF. It is also
readable with libpcap.

Let's assign a specific -Dcryptolib= value to each job to have at least
some coverage for all supported cryptolibs without unnecessarily
multiplying the test matrix.
Should provide coverage for #21880.
Previously, when -Ddns-over-tls=false, libopenssl was missing in the
dependency of resolved.
Also, this drops libgpg_error when it is not necessary.
Replaces #21878.
Fixes#21872.
log_syntax_callback sets 's', a.k.a. '*userdata', to POINTER_MAX to signal allocation failure.
If the error does not cause immediate failure of the program, and log_syntax_callback is called
again, it would try to use 's' as a pointer to a set and fail badly.
This explicitly mentions that comments and empty lines are supported
(and ignored) in /etc/locale.conf. It then adds ownership reference
to the factory default.
LibLocateProtocol will return the protocol for the first device that
supports it. But it may not actually come from the ConIn device that
we want to use here.
This should be the root cause of what was previously considered just
broken firmware. If you ask the wrong device to return some key, of
course it will never provide one.
This changes the way we handle input yet again in light of this new
knowledge and because using the correct TextInputEx with fallback to
ConIn can actually create double input in some cases.
Since we are now confident that we get the right TextInputEx, we can
use that exclusively, only falling back to ConIn if the console input
device does not support the better interface (the spec is pretty clear
that it must support it, though).
Because some firmware is broken, we still need to provide a fallback
to the previously used TextInputEx thats overrides ConIn/ConInEx if
it is functional.
This adds /etc/locale.conf to the set of configuration files
populated by tmpfiles.d factory /etc handling.
In particular, the build-time locale configuration in systemd is
now wired to a /usr factory file, and installed to the system.
On boot, if other locale customization tools did not write
/etc/locale.conf on the system, the factory default file gets
copied to /etc by systemd-tmpfiles.
This is done in order to avoid skews between different system
components when no locale settings are configured. At that point,
systemd can safely act as the fallback owner of /etc/locale.conf.
Also fixes the following:
- IPServiceType= is moved to [DHCPv4] section,
- drop an incorrect sentence in RouteMTUBytes= in [DHCPv4] section.
- drop unnecessary word 'unsigned'.
afl-clang and hufzz-clang try to instrument the code and the
underlying compilers don't like it. It should probably be
fixed in both afl and honggfuzz eventually but until then
let's just use "raw" clang to build bpf-skeletons.
It's a follow-up to https://github.com/systemd/systemd/pull/21607
The user may be busy when auto-rebalancing the user's home device.
