Let's make it easier to figure out when we see an invalid journal file, why we
consider it invalid, and add some minimal debug logging for it.
This log output is normally not seen (after all, this all is library code),
unless debug logging is exlicitly turned on.
When date is changed in system to future and normal user logs to new journal file, and then date is changed back to present time, the "journalctl --list-boot" command goes to forever loop. This commit tries to fix this problem by checking first the boot id list if the found boot id was already in that list. If it is found, then stopping the boot id find loop.
Like the Inspiron 1520, the Dell Latitude 2110 emits brightness-control
key events both through atkbd and acpi-video. This suppresses them on
the atkbd side.
Lets go further and make /lib/modules/ inaccessible for services that do
not have business with modules, this is a minor improvment but it may
help on setups with custom modules and they are limited... in regard of
kernel auto-load feature.
This change introduce NameSpaceInfo struct which we may embed later
inside ExecContext but for now lets just reduce the argument number to
setup_namespace() and merge ProtectKernelModules feature.
This is useful to turn off explicit module load and unload operations on modular
kernels. This option removes CAP_SYS_MODULE from the capability bounding set for
the unit, and installs a system call filter to block module system calls.
This option will not prevent the kernel from loading modules using the module
auto-load feature which is a system wide operation.
Allowed paths are unified betwen the configuration file parses and the bus
property checker. The biggest change is that the bus code now allows "block-"
and "char-" classes. In addition, path_startswith("/dev") was used in the bus
code, and startswith("/dev") was used in the config file code. It seems
reasonable to use path_startswith() which allows a slightly broader class of
strings.
Fixes#3935.
If `--test` command line option was passed, the systemd set skip_setup
to true during bootup. But after this we check again that arg_action is
test or help and opens pager depends on result.
We should skip setup in a case when `--test` is passed, but it is also
safe to set skip_setup in a case of `--help`. So let's remove first
check and move skip_setup = true to the second check.
This makes it easier to debug failed nspawn invocations:

If stdin is supplied as an fd for transient units (using the
StandardInputFileDescriptor pseudo-property for transient units), then we
should also fix up the TTY ownership, not just when we opened the TTY
ourselves.
This simply drops the explicit is_terminal_input()-based check. Note that
chown_terminal() internally does a much more appropriate isatty()-based check
anyway, hence we can drop this without replacement.

`systemctl isolate initrd-switch-root.target` called by initrd-cleanup.service
kills initrd-cleanup.service itself. Then, initrd-cleanup.service failed and
system goes to emergency shell.
To prevent this problem, this commit adds `Wants=initrd-cleanup.service` to
initrd-switch-root.target.
fixes: #4343.
r was not initialized and would be used if "tcp" was the only option
used for the stub. We should initialize it to 0 to indicate that no
error happened in the udp case.
SIGTERM should be considered a clean exit code for daemons (i.e. long-running
processes, as a daemon without SIGTERM handler may be shut down without issues
via SIGTERM still) while it should not be considered a clean exit code for
commands (i.e. short-running processes).
Let's add two different clean checking modes for this, and use the right one at
the appropriate places.
Fixes: #4275
When we print information about PID 1's crashdump subprocess failing. In this
case we *know* that we do not generate LSB exit codes, as it's basically PID 1
itself that exited there.
Previously we've used free_and_strdup() to fill arg_default_unit with unit
name, If we didn't pass default unit name through a kernel command line or
command line arguments. But we can use just strdup() instead of
free_and_strdup() for this, because we will start fill arg_default_unit
only if it wasn't set before.
Let's get rid of is_clean_exit_lsb(), let's move the logic for the special
handling of the two LSB exit codes into the sysv-generator by writing out
appropriate SuccessExitStatus= lines if the LSB header exists. This is not only
semantically more correct, bug also fixes a bug as the code in service.c that
chose between is_clean_exit_lsb() and is_clean_exit() based this check on
whether a native unit files was available for the unit. However, that check was
bogus since a long time, since the SysV generator was introduced and native
SysV script support was removed from PID 1, as in that case a unit file always
existed.
We are going to add this child as a source to our event loop so we don't
want to block when reading data from it as this will prevent us from
processing other events. Specifically this will block the signalfds
which means if we are waiting for data from curl we won't handle SIGTERM
or SIGINT until we happen to get more data.
