^D works in emergency.service too. One needs to log in when in rescue
mode too.

They both use StandardInput=tty-force so they cannot be run
concurrently.

Also make pointer calculations more explicit so they are
easier to understand.

The whole DHCPv6 test message length was incorrectly used as the length
of DHCPv6 options causing the following bad memory access:
$ build/test-dhcp6-client
Assertion 'interface_index >= -1' failed at ../src/libsystemd-network/sd-dhcp6-client.c:129, function sd_dhcp6_client_set_index(). Ignoring.

We can't use LZ4_compress_limitedOutput_continue() because in the
worst-case scenario the compressed output can be slightly bigger than
the input block. This generally affects very few blocks and is no reason
to abort the compression process.
I ran into this when I noticed that Chromium core dumps weren't being
compressed. After switching to LZ4_compress_continue() a ~330MB Chromium
core dump gets compressed to ~17M.

Those symbols were introduced in commit
14cb733684d3c3f50d088a3a370ddf8e8894dfa4 and released in v215.

Since c6a373a2634854, we might encounter unit templates via the
'list-units' verb. These aren't restartable (and we throw errors), so
make sure they're filtered out of the completion options.

NTPv4 servers don't reply with unsynchronized status when they lost
synchronization, they only keep increasing the root dispersion and it's
up to the client to decide at which point they no longer consider it
synchronized.
Ignore replies with root distance over 5 seconds.

The kernel timestamp (recv_time) is made earlier than current time
(now_ts), use the timestamp captured before sending packet directly.

free_and_strdup() does exactly the same as sd_event_source_set_name(), use
it!
|
|
This should help in debugging failing event sources.

Skipping interfaces randomly without the caller specifying it is nasty.
Avoid this and let the caller do that themselves.

The sd_bus_emit_properties_changed() call for x11 keymap changes lacks
commas.. whoops. Fix it! Now localed emits PropertiesChanged signals
again.

removes code duplication
also move switch-root to shared

Similar to container_of(), we now use unique variable names for the bascic
math macros MAX, MIN, CLAMP, LESS_BY. Furthermore, unit tests are added to
verify they work as expected.
For a rationale, see:

shared: make container_of() use unique variable names

We must not access slot->floating after we possible dropped the last
reference to it. Fix all callback-invocations to first check
slot->floating and possible disconnect the slot, then release the last
reference.

Don't leak the device-names during device destruction in sysview. Somehow,
the device-name is "const char*", so make it "char*" first to avoid
warnings when calling free() on it.

Fix leaking the xkb-state during keyboard destruction, leaking lots of xkb
references into the wild.

Use SETLINK when modifying an existing link.

In case 'scan_evdev' and 'scan_drm' are both false, we never set 'r' to
anyhting, thus return an uninitialized error code. Fix this by always
returning 0 as we catch negative codes earlier, anyway. Thanks to Thomas
H.P. Anderson for the report.

If the journal is corrupted, we might return an object that does
not start with the expected field name and/or is shorter than it
should.

Before forking, block all signals, and unblock them afterwards. This way
the child will have them blocked, and we won't lose them.
|
|
This should be moved to man pages, but for now the C code is included directly.
Suggested by Zbyszek.

Like systemd-subterm, this new systemd-evcat tool should only be used to
debug libsystemd-terminal. systemd-evcat attaches to the running session
and pushes all evdev devices attached to the current session into an
idev-session. All events of the created idev-devices are then printed to
stdout for input-event debugging.
