That way we can use it in nspawn.
Also, while we are at it, let's rename the call config_parse_rlimit(),
i.e. insert the "r", to clarify what kind of limit this is about.
Configuration through environment variable is inconvenient with meson, because
they cannot be convieniently changed and/or are not preserved during
reconfiguration (https://github.com/mesonbuild/meson/issues/1503).
This adds -Dvalgrind=true/false, which has the advantage that it can be set
at any time with meson configure -Dvalgrind=... and ninja will rebuild targets
as necessary. Additional minor advantages are better consistency with the
options for hashmap debugging, and typo avoidance with '#if' instead of '#ifdef'.
What the man page said was different than what the code did.
save_external_coredump() will store the core temporarily for backtrace
generation, and will delete if afterwards if it is too large. So to disable
processing, it's necessary to both set
Storage=none/Storage=journal+JournalSizeMax=0/Storage=external+ExternalSizeMax=0
and ProcessSizeMax=0. This updates the man page to reflect the code.
The man pages are extended to describe that Storage=none + ProcessSizeMax=0 is
the simplest way to disable coredump processing. All the storage and processing
options make this quite complicated, so let's add a copy-and-pasteable example
of how to disable coredump. Doing it through coredump.conf has the advantage
that we still log, and the effect is immediate, unlike masking the sysconf
file.
Fixes#8788.
If messages are wrapped, then only the last line is shown in the
dialog, at least polkit gui for Xfce. It may be a bug of polkit or
Xfce. But it is not necessary to wrap the message in the policy
file. So, let's fix them.
LUKS2 header supports to device label and blkid since 2.32 version
already supports this option.
Persistent udev storage rules should create symlink for this label.
For older devices this value is not set so changed rule should be compatible.
Commenting out "WatchdogTimeout=3min" in systemd-logind.service causes
NotifyAccess to go from "main" to "none", breaking support for logind
restart. Let's fix that.
The protocol is that a string is serialized with the nul byte at the end, and
the terminator is included in length. We'd call strndup with offset 0, length
len1-1, and then a second time with offset len1, length len2-1, so in the end
the check was off by one. But let's require the terminating nul too, even if
we don't access it.
CID #1383035.
This is external data, even if trusted. We should not assert on it, but verify
and return proper error instead, which assert_return does. In particular,
write(2) says that a partial write could occur when interupted by a signal.
When compiled with asserts disabled, we could access memory outside of the
allocated buffer.
CID #1237671.
Follow-up for 1a96c8e1cc.
Initializing just some of the values doesn't make sense. We should handle them
all in the same way. In those tests there are no jumps, all steps are covered
with assert_se(), so we know everything will be set if we get to the end of the
function. And _not_ initializing those variables has the advantage that it
allows valgrind to catch potential initalization errors in the function being
tested.
We were inconsitently using them in some cases, but in majority not.
Using assignment in assert_se is very common, not an exception like in
'if', so let's drop the extra parens everywhere.
If completion is attempted on an invalid path, busctl might respond with an error.
This shouldn't be seen, introspection is supposed to just fail silently.
Since StandardOutput=file:path is more similar to StandardInput= than
StandardInputText=, and only StandardInput= is actually documented above
StandardOutput= whereas StandardInputText= is documented below it, I
assume the intention was to refer to the former.
We'd write a sequence that was invalid unicode and this caused the d-bus
connection to be terminated:
$ busctl get-property org.freedesktop.systemd1 /org/freedesktop/systemd1/unit/dbus_2esocket org.freedesktop.systemd1.Unit SubState
s "running"
$ busctl get-property org.freedesktop.systemd1 /org/freedesktop/systemd1/unit/dbus_e2socket org.freedesktop.systemd1.Unit SubState
Remote peer disconnected
$ busctl get-property org.freedesktop.systemd1 /org/freedesktop/systemd1/unit/dbus_e2socket org.freedesktop.systemd1.Unit SubState
(hangs)
Fixes#8978.
When I see "test", I have to think three times what the return value
means. With "below" this is immediately clear. ratelimit_below(&limit)
sounds almost like English and is imho immediately obvious.
(I also considered ratelimit_ok, but this strongly implies that being under the
limit is somehow better. Most of the times this is true, but then we use the
ratelimit to detect triple-c-a-d, and "ok" doesn't fit so well there.)
