This path to ping is compatible with both debian-like and usr-merged
distros. This keeps the test simple, and should thus pass everywhere.
Fixes: #7267
- 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.
The linux umount2() systemcall accepts a MNT_FORCE flags
which some filesystems honor, particularly FUSE and various
network filesystems such as NFS.
These filesystems can sometimes wait for an indefinite period
for a response from an external service, and the wait if
sometimes "uninterruptible" meaning that the process cannot be
killed.
Using MNT_FORCE causes any such request that are outstanding to
be aborted. This normally allows the waiting process to
be killed. It will then realease and reference it has to the
filesytem, this allowing the filesystem to be unmounted.
If there remain active references to the filesystem, MNT_FORCE
is *not* forcefull enough to unmount the filesystem anyway.
By the time that umount_all() is run by systemd-shutdown, all
filesystems *should* be unmounted, and sync() will have been
called. Anything that remains cannot be unmounted in a
completely clean manner and just nees to be dealt with as firmly
as possible. So use MNT_FORCE and try to explain why in the
comment.
Also enhance an earlier comment to explain why umount2() is
safe even though mount(MNT_REMOUNT) isn't.
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.
job_finish_and_invalidate() calls job_free() to destroy jobs (and remove
them from the dbus queue). So we don't need to add them to the dbus queue
first.
We only want to add jobs to the dbus queue if they're a restart job, which
we're transmogrifying into a start job and putting back into the system.
During startup of networkd we try to drop the configs. While droping
routes we filling ip route type and because of which message like
```
host: Could not drop route: Invalid argument
host: Could not drop route: Invalid argument
```
are shown.
Closed#6929
_unused_ means "the variable is meant to be possible unused and gcc
will not generate a warning about it", which is exactly what we need here,
since we're only declaring it for the side effect of _cleanup_.
clang warns about a few sites like this:
../src/journal/journal-file.c:1780:48: warning: taking address of packed member 'entry_offset' of class or structure 'DataObject' may result in an unaligned pointer value [-Waddress-of-packed-member]
&o->data.entry_offset,
^~~~~~~~~~~~~~~~~~~~
but DataObject.entry_offset will always be 8-byte aligned as long as
the DataObject structure is aligned. Similarly in other cases, the
field is always aligned. Let's just silence the warning to avoid noise.
gcc does not know -Waddress-of-packed-member, and would warn about an unknown
warning, so we need to conditionalize on __clang__.
../src/network/networkd-link.c:3577:84: warning: format specifies type 'unsigned char' but the argument has type 'uint32_t' (aka 'unsigned int') [-Wformat]
route->dst_prefixlen, route->tos, route->priority, route->table, route->lifetime);
^~~~~~~~~~~~
../src/network/networkd-manager.c:1146:132: warning: format specifies type 'unsigned char' but the argument has type 'uint32_t' (aka 'unsigned int') [-Wformat]
rule->from_prefixlen, space ? " " : "", to_str, rule->to_prefixlen, rule->tos, rule->fwmark, rule->fwmask, rule->table);
^~~~~~~~~~~
Also add some line breaks to make it easier to see which argument is for which
part of the format string.
clang warns:
../src/import/importd.c:254:70: warning: 'break' is bound to current loop, GCC binds it to the enclosing loop [-Wgcc-compat]
while ((e < t->log_message + t->log_message_size) && IN_SET(*e, 0, '\n'))
^
Let's just play it safe and not use IN_SET here.
../src/journal/journald-native.c:341:13: warning: variable 'context' is used uninitialized whenever 'if' condition is false [-Wsometimes-uninitialized]
if (ucred && pid_is_valid(ucred->pid)) {
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
../src/journal/journald-native.c:350:42: note: uninitialized use occurs here
context, ucred, tv, label, label_len);
^~~~~~~
../src/journal/journald-native.c:335:31: note: initialize the variable 'context' to silence this warning
ClientContext *context;

= NULL
Very nice reporting!
Functions that we call can handle context == NULL, so it's enough to simply
initialize the variable.
Failure to spawn ExecStartPost was being handled differently to e.g.
EXIT_FAILURE returned by ExecStartPost. It looks like this was an
oversight. Fix to match documented behaviour.
`man systemd.service`:
> Note that if any of the commands specified in ExecStartPre=, ExecStart=,
> or ExecStartPost= fail (and are not prefixed with "-", see above) or time
> out before the service is fully up, execution continues with commands
> specified in ExecStopPost=, the commands in ExecStop= are skipped.
Update the timeout warnings for remount and unmount. For consistency with
mount, for accuracy, and for consistency with their equivalents in
service.c.
manager_connect_bus() is called *before* manager_coldplug(). As a last
thing in service_coldplug() we set service state to
s->deserialized_state, and thus before we do that all services are
inactive and try_connect always evaluates to false. To fix that we must
look at deserialized state instead of current unit state.
Fixes#7146
