Files which are installed as-is (any .service and other unit files, .conf
files, .policy files, etc), are left as is. My assumption is that SPDX
identifiers are not yet that well known, so it's better to retain the
extended header to avoid any doubt.
I also kept any copyright lines. We can probably remove them, but it'd nice to
obtain explicit acks from all involved authors before doing that.
Follow-up for ba7f4ae617.
By default, we detect if the real root has a separate /usr/sbin directory, but
this can be overrides with -Dsplit-bin=true|false. The check assumes that
/usr/sbin is split if it is not a symlink, so it'll return a false negative
with some more complicated setups. But that's OK, in those cases this should be
configured explicitly.
This will copy the structure of the directories in the root file system to
$DESTDIR. If a directory is a directory in $DESTDIR but a symlink in the root
file system, this script will fail. This means that it's not possible to reuse
a $DESTDIR from between ba7f4ae61 and this patch.
Add a new -Dllvm-fuzz=true option that can be used to build against
libFuzzer and update the oss-fuzz script to work outside of the
oss-fuzz build environment.
The fuzzers will be used by oss-fuzz to automatically and
continuously fuzz systemd.
This commit includes the build tooling necessary to build fuzz
targets, and a fuzzer for the DNS packet parser.
Currently there is no way to prevent tests from building using meson.
This introduces two problems:
1) It adds a extra 381 files to compile.
2) One of these tests explicitly requires libgcrypt to be built even if systemd
is not using it.
3) It adds C++ to the requirements to build systemd.
When cross-compiling, this is uneccessary.
On a typical system running systemd, the telinit in PATH is very likely to be a symlink
to systemctl. Setting TELINIT to this may result in an infinite recursion if telinit is called
and sd_booted() == 0. This may commonly occur in a chroot environment.

[zj:
The path was originally hardcoded as "/lib/upstart/telinit", but was made configurable without
changing the default in 4ad61fd180. Then the default was
changed to `/lib/sysvinit/telinit` in abaaabf40a. Then it
started being autodetected when meson support was added in
5c23128dab. This patch restores the behaviour that was
implemented in configure.ac at the time of its removal.]
To allow better integration with distributions requiring an explicitly
set gid for the `users` group, provide the new `-Dusers-gid` option to
set to a new numeric value.
In the absence of a specified gid, we'll fallback to the default existing
behaviour of `-` as the gid value, to automatically assign the next available
gid on the system.
So far I avoided adding license headers to meson files, but they are pretty
big and important and should carry license headers like everything else.
I added my own copyright, even though other people modified those files too.
But this is mostly symbolic, so I hope that's OK.
- Remove the uaccess tag from /dev/dri/renderD*.
- Change the owning group from video to render.
- Change default mode to 0666.
- Add an option to allow users to set the access mode for these devices at
compile time.
This changes the symbolic name for the default gateway from "gateway" to
"_gateway". A new configuration option -Dcompat-gateway-hostname=true|false
is added. If it is set, the old name is also supported, but the new name
is used as the canonical name in either case. This is intended as a temporary
measure to make the transition easier, and the option should be removed
after a few releases, at which point only the new name will be used.
The old "gateway" name mostly works OK, but hasn't gained widespread acceptance
because of the following (potential) conflicts:
- it is completely legal to have a host called "gateway"
- there is no guarantee that "gateway" will not be registered as a TLD, even
though this currently seems unlikely. (Even then, there would be no
conflict except for the case when the top-level domain itself was being resolved.
The "gateway" or "_gateway" labels have only special meaning when the
whole name consists of a single label, so resolution of any subdomain
of the hypothetical gateway. TLD would still work OK. )
Moving to "_gateway" avoids those issues because underscores are not allowed
in host names (RFC 1123, §2.1) and avoids potential conflicts with local or
global names.
v2:
- simplify the logic to hardcode "_gateway" and allow
-Dcompat-gateway-hostname=true as a temporary measure.
This is just the meson part, no functional change.
Use meson -D slow-tests=yes to set the default,
or SYSTEMD_SLOW_TESTS=yes build/test-foobar for just one test.
Setting the default is more useful for installed tests.
libidn2 2.0.0 supports IDNA2008, in contrast to libidn which supports IDNA2003.
https://bugzilla.redhat.com/show_bug.cgi?id=1449145
From that bug report:
Internationalized domain names exist for quite some time (IDNA2003), although
the protocols describing them have evolved in an incompatible way (IDNA2008).
These incompatibilities will prevent applications written for IDNA2003 to
access certain problematic domain names defined with IDNA2008, e.g., faß.de is
translated to domain xn--fa-hia.de with IDNA2008, while in IDNA2003 it is
translated to fass.de domain. That not only causes incompatibility problems,
but may be used as an attack vector to redirect users to different web sites.
v2:
- keep libidn support
- require libidn2 >= 2.0.0
v3:
- keep dns_name_apply_idna caller dumb, and keep the #ifdefs inside of the
function.
- use both ±IDN and ±IDN2 in the version string
Some distros (openSUSE) don't have group shadow support enabled. This can lead
to the following error:
# systemd-sysusers
Creating group foofoo with gid 478.
# systemd-sysusers
# groupdel foofoo
# systemd-sysusers
Creating group foofoo with gid 478.
Failed to write files: File exists
This patch adds --disable-gshadow option to configure. If used,
systemd-sysvusers won't consider /etc/gshadow.
Also detect libgpg-error. Require both to be present for HAVE_CRYPT,
even though libgpg-error is only used in src/resolve. If one is available,
the other should be too, so it doesn't seem worth the trouble to make two
separate conditions.
This makes the helper binaries significantly bigger (in some cases, the final
size depends on link options and optimization level), and is only useful for
distributions which want to provide the option to install udev without systemd.
As the linking is improved, the difference between the columns might shrink,
but it's unlikely that linking libshared statically could ever be more
efficient.
E.g. with -O0, no -flto:
(static) (shared)
src/udev/ata_id 999176 85696
src/udev/cdrom_id 1024344 111656
src/udev/collect 990344 81280
src/udev/scsi_id 1023592 115656
src/udev/v4l_id 811736 17744
When linked dynamically, install_rpath must be specified, so add that.
This doesn't feel as natural, but is more consistent with the boolean options
which require true/false, and allows setting of options without knowing of
which type the option is.
This is a very straightforward conversion of the rules in Makefile.am.
Generated objects (on arm64) are identical.
The only difference in executed commands is that automake uses ld -m
elf_x86_64, without us specifying the -m option anywhere. I suspect that
using the default for the given linker should be OK, so it's fine to just
skip it.
