mkdir -p is called both when setting up the autofs mount, as well
as after being notified that the real mount unit should be called.
However the first mkdir -p is hardcoded with 0555, while the second
uses the value specified to DirectoryMode in the automount unit; the
second mkdir -p is only needed when called from coldplug, so under
normal operation the dirs are incorrectly created with mode 0555.
This replaces the hardcoded 0555 mode with the value of DirectoryMode.
Closes#13683.
Inside container, writing file returns EACCESS. Moreover, some devices
return ENODEV rather than EACCES. So, let's also ignore these two
error causes.
Closes#13652.
We should never have used an unprefixed environment variable name.
All other systemd-nspawn variables have the "SYSTEMD_NSPAWN_" prefix,
and all other systemd variables have the "SYSTEMD_" prefix.
The new variable name takes precedence, but we fall back to checking the
old one. If only the old one is found, a warning is emitted.
In addition, SYSTEMD_NSPAWN_UNIFIED_HIERARCHY="" is accepted as an override
to avoid looking for the old variable name.
We have a variable with the same name ($UNIFIED_CGROUP_HIERARCHY) in tests,
which governs both systemd-nspawn and qemu behaviour. It is not renamed.
We would parse the environment twice (to re-apply settings after reading
config from disk), but we would not check the return code first time.
This means that for some settings we would ignore invalid values, while
for others, we'd fail at some point.
Let's just consistently fail. Those environment variables define important
aspects of behaviour, and it is better for the user if we ignore invalid
values. (Unknown settings are still ignored, so forward compatibility is
maintained.)
libcryptsetup v2.0.1 introduced new API calls, supporting 64 bit wide
integers for `keyfile_offset`. This change invokes the new function
call, gets rid of the warning that was added in #7689, and removes
redundant #ifdefery and constant definitions.
See https://gitlab.com/cryptsetup/cryptsetup/issues/359.
Fixes#7677.
A later version of the DefaultMemory{Low,Min} patch changed these to
require explicitly setting memory_foo_set, but we only set that in
load-fragment, not dbus-cgroup.
Without these, we may fall back to either DefaultMemoryFoo or
CGROUP_LIMIT_MIN when we really shouldn't.
This is an oversight from https://github.com/systemd/systemd/pull/12332.
Sadly the tests didn't catch it since it requires a real cgroup
hierarchy to see, and it wasn't seen in prod since we're only currently
using DefaultMemoryLow, not DefaultMemoryMin. :-(
Currently systemd will treat smb3 as local filesystem and cause
can't boot failures. Add smb3 to the list of remote filesystems
to fix this issue.

As documented in the man-page, readdir() may return a directory entry with
d_type == DT_UNKNOWN. This must be handled for regular filesystems.
dirent_ensure_type() is available to set d_type if necessary. Use it in
some more places.
Without this systemd will fail to boot correctly with nfsroot and some
other filesystems.
Closes#13609
On one of my test machines, test-path-util was failing because the
find_binary("xxxx-xxxx") was returning -EACCES instead of -ENOENT. This
happens because the PATH entry on that host contains a directory which
the user in question doesn't have access to. Typically applications
ignore permission errors when searching through PATH, for example in
bash:
$ whoami
cdown
$ PATH=/root:/bin type sh
sh is /bin/sh
This behaviour is present on zsh and other shells as well, though. This
patch brings our PATH search behaviour closer to other major Unix tools.
IPServiceType set to CS6 (network control) causes problems on some old
network setups that continue to interpret the field as IP TOS.
Make DHCP work on such networks by allowing this field to be set to
CS4 (Realtime) instead, as this maps to IPTOS_LOWDELAY.

See https://bugzilla.redhat.com/show_bug.cgi?id=1731772:
when autofs4 is disabled in the kernel,
proc-sys-fs-binfmt_misc.automount is not started, so the binfmt_misc module is
never loaded. If we added a dependency on proc-sys-fs-binfmt_misc.mount
to systemd-binfmt.service, things would work even if autofs4 was disabled, but
we would unconditionally pull in the module and mount, which we don't want to do.
(Right now we ony load the module if some binfmt is configured.)
But let's make it easier to handle this case by doing two changes:
1. order systemd-binfmt.service after the .mount unit (so that the .service
can count on the mount if both units are pulled in, even if .automount
is skipped)
2. add [Install] section to the service unit. This way the user can do
'systemctl enable proc-sys-fs-binfmt_misc.mount' to get the appropriate behaviour.
ARPHRD_NETROM was excluded, most likely just because it is protocol No. 0,
and ARPHRD_CISCO was reported under its alias name "HDLC". Let's just
allow defined aliases under the main name.
Our biggest object in libsystemd was a table full of zeros, for the arphdr
names. Let's use a switch (which gcc nicely optimizes for us), instead a
table with a gap between 826 and 65534:

No functional change.
Introduce support for configuring cpus and mems for processes using
cgroup v2 CPUSET controller. This allows users to limit which cpus
and memory NUMA nodes can be used by processes to better utilize
system resources.
The cgroup v2 interfaces to control it are cpuset.cpus and cpuset.mems
where the requested configuration is written. However, it doesn't mean
that the requested configuration will be actually used as parent cgroup
may limit the cpus or mems as well. In order to reflect the real
configuration cgroup v2 provides read-only files cpuset.cpus.effective
and cpuset.mems.effective which are exported to users as well.
