RuntimeDirectory= often used for sharing files or sockets with other
services. So, if creating them under private/ sub-directory, we cannot
set DynamicUser= to service units which want to share something through
RuntimeDirectory=.
This makes the directories given by RuntimeDirectory= are created under
/run/ even if DynamicUser= is set.
Fixes#7260.
When at least one of BindPaths=, BindReadOnlyPaths=, RootImage=,
RuntimeDirectory= or their friends are set, systemd prepares
a namespace under /run/systemd/unit-root. Thus, ReadWritePaths=
or their friends without '+' prefix is completely meaningless.
So, let's assume '+' prefix when one of them are set.
Fixes#7070 and #7080.
The error message corresponds to EILSEQ is "Invalid or incomplete
multibyte or wide character", and is not suitable in this case.
So, let's show a custom error message when the function
dynamic_creds_realize() returns -EILSEQ.
This makes systemd supports the case that DynamicUser=yes and
static user and group exist such that uid and gid of them are different.
We only refuse the operation when user does not exist but the group
with the same name exists.
Fixes#7013.
If sd_bus_open_system() fail, then try to read information about
dynamic users from /run/systemd/dynamic-uid.
This makes services can successfully call getpwuid() or their friends
even if dbus.service is not started yet.
Fixes#6967.
From bce67bbee3, systemd-networkd always shows
```
rtnl: received address with invalid family type 32, ignoring.
```
during boot-up. In the code, there are log_warning() and log_debug() for the
same situation, and the log_debug() is never called. So, let's lower the
log level and remove never called function.
`journalctl -o export | systemd-journal-remote -o /tmp/dir -`
gives the following error messages.
```
Failed to open output journal /tmp/dir: Invalid argument
Failed to get writer for source stdin: Invalid argument
Failed to create source for fd:0 (stdin): Invalid argument
```
And these are hard to understand what is the problem.
This commit makes journal-remote check whether the output file name
ends with .journal suffix or not, and if not, output error message.
The directories are only used by the specific services, and
created before the services are started. So, it is not necessary
to create them by systemd-tmpfiles.
The option MHD_OPTION_STRICT_FOR_CLIENT is provided since libmicrohttpd-0.9.54, and
MHD_USE_PEDANTIC_CHECKS will be deprecated in future.
This makes support both option.
The option MHD_USE_THREAD_PER_CONNECTION requires MHD_USE_POLL_INTERNAL_THREAD
since libmicrohttpd-0.9.53.
If MHD_USE_POLL is used instead of MHD_USE_POLL_INTERNAL_THREAD, then
the library outputs the following warning:
```
Warning: MHD_USE_THREAD_PER_CONNECTION must be used only with
MHD_USE_INTERNAL_POLLING_THREAD. Flag MHD_USE_INTERNAL_POLLING_THREAD was added.
Consider setting MHD_USE_INTERNAL_POLLING_THREAD explicitly.
```
The option MHD_USE_POLL_INTERNAL_THREAD is defined as
`MHD_USE_POLL_INTERNAL_THREAD = MHD_USE_POLL | MHD_USE_INTERNAL_POLLING_THREAD,`
So, let's use MHD_USE_POLL_INTERNAL_THREAD instead of MHD_USE_POLL.
Without this fix:
$ systemctl start <tab>
Display all 135 possibilities? (y or n)
$ __get_startable_units --system | wc -l
224
the number of the suggestions are quite different, as __get_startable_units --system does
not filter already started units. With this fix,
$ systemctl start <tab>
Display all 135 possibilities? (y or n)
$ __get_startable_units --system | wc -l
123
$ __get_template_names --system | wc -l
12
the number of the suggestions matches one the function returns.
For consistency with the other internal functions, it should use the first argument
instead of the global variable $mode.
[zj: add commit message to make it sound like we know what we're doing]
Since 3536f49e8f, manager_new() in
user mode requires XDG_RUNTIME_DIR is set. So, in this commit,
setup_fake_runtime_directory() is added in the beginning of test.
Fixes an issue comment in #6384.
This introduces {State,Cache,Log,Configuration}Directory= those are
similar to RuntimeDirectory=. They create the directories under
/var/lib, /var/cache/, /var/log, or /etc, respectively, with the mode
specified in {State,Cache,Log,Configuration}DirectoryMode=.
This also fixes#6391.
