Binaries might not initialize SELinux, e.g. when they normally do not
create files with the SELinux default context.
If they, via an internal libary function, call a _label() function,
mac_selinux_maybe_reload() gets called. Since the SELinux status page
has not been opened, selinux_status_updated() will fail with EINVAL.
This affects particularly test binaries.
Just exit early and avoid confusing debug logs.
Let's make sure we keep a reference to the event source
(Note that this code is currently not used, which is why this was never
used: in all cases we do not add listener fds after the event is
attached, but before. In that case this code is not called.)
We support read-only ptyfwd options, and on those the input event source
won't be allocated. Deal with that and don't invoke a function on it
that will then instantly fail.
So far we kept all defines directly originating from the spec in
sd-bus-protocol.h, do this for this too.
The precise place doesn't matter much API-wise given that sd-bus.h includes
sd-bus-protocol.h, hence let's just clean this up.
This is useful information, I don't know why we forgot to add it there.
gcc doesn't like arithemetic on a pointer to a function or void*, so don't
print signedness info there. It doesn't matter anyway.
C says function pointers can be different... Though I guess our code isn't
prepared for that.
If the directory (/var/lib/private is most likely) has borked permissions, the
test will fail with a cryptic message and EXIT_STATE_DIRECTORY or similar. The
message from the child with more details gets lost somewhere. Let's avoid running
the test in that case and provide a simple error message instead.
E.g. systemd-238-12.git07f8cd5.fc28.ppc64 (which I encountered on a test machine)
has /var/lib/private with 0755.
All backslashes that should be single in shell syntax need to be written as "\\" because
our parser will remove one level of quoting. Also, single quotes were doubly nested, which
cannot work.
Should fix the following message:
test-execute/exec-dynamicuser-statedir.service:16: Ignoring unknown escape sequences: "test $$(find / \( -path /var/tmp -o -path /tmp -o -path /proc -o -path /dev/mqueue -o -path /dev/shm -o -path /sys/fs/bpf -o -path /dev/.lxc \) -prune -o -type d -writable -print 2>/dev/null | sort -u | tr -d \\n) = /var/lib/private/quux/pief/var/lib/private/waldo"
The new methods work as the unflavoured ones, but takes flags as a
single uint64_t DBUS parameters instead of different booleans, so
that it can be extended without breaking backward compatibility.
Add new flag to allow adding/removing symlinks in
[/etc|/run]/systemd/system.attached so that portable services
configuration files can be self-contained in those directories, without
affecting the system services directories.
Use the new methods and flags from portablectl --enable.
Useful in case /etc is read-only, with only the portable services
directories being mounted read-write.
