Fix journalctl --dump-catalog, journalctl --list-catalog
|
|
Expose `DefaultLimit*` as properties on dbus
|
|
Make journald audit socket maskable
|
|
man: describe IPv6AcceptRouterAdvertisements= better
|
|
Fixes #1514.
|
|
`journalctl --dump-catalog ID1 ID2 ...` works fine.
|
|
|
|
Adding them to the documentation makes it easier to find
the right man page for people who are trying to understand
where some socket in the filesystem is coming from.
|
|
With the previous description it wasn't clear that the
kernel default is being described.
Add link to kernel docs.

If we were given some sockets through socket activation, and audit
socket is not among them, do not try to open it. This way, if the
socket unit is disabled, we will not receive audit events.

sd-daemon: wipe out memory before using CMSG_NXTHDR()
|
|
CMSG_NXTHDR() checks for cmsg->cmsg_len *after* it increased the pointer.
While this makes sense for parsing received messages, that's a pitfall
for code crafting messages with this macro.
Wipe out the allocated memory to fix this.

nspawn: create /sys/fs/cgroup for unified hierarchy as well
|
|
Otherwise, we might end up trying to isolate it away when starting user
instances.
While we are at it, also prohibit manual start/stop of these two units.
Fixes: #1507
|
|
No change in behaviour, just make the code more obvious.
|
|
We already stop boot if /etc/mtab is not a symlink right now, and most
likely we'll stop referecing it at all in the future, either way there's
no point in keeping it around as taint flag.

systemd-run can launch units with SyslogIdentifier and SyslogLevelPrefix

Make sure the mount units pulled by 'RequiresMountsFor=' are loaded, if they exist

exist)
We should make sure that mount units involved by 'RequiresMountsFor='
directives are really loaded if not required by any others units so
that Requires= dependencies on the mount units are applied and thus
the mount unit dependencies are started.

allow passing in fds for stdin/stdout/stderr for transient services
|
|
Rename struct 'tlv_packet' to 'sd_lldp_packet' and struct
'tlv_section' to 'sd_lldp_section' since the former is referenced in
public header sd-lldp.h.

core: manager: add some missing properties

Before, we'd always reset acquired terminals, which is not really
desired, as we expose a setting TTYReset= which is supposed to control
whether the TTY is reset or not. Previously that setting would only
enable a second resetting of the TTY, which is of course pointless...
Hence, move the implicit resetting out of acquire_terminal() and make
the callers do it if they need it.
|
|
With this change we'll open the shell's tty right from machined and then
pass it to the transient unit we create. This way we make sure the pty
is opened exactly as long as the transient service is around, and no
longer, and vice versa. This way pty forwarders do not have to deal with
EIO problems due to vhangup, as the pty is open all the time from the
point we set things up to the point where the service goes away.
|
|
fixes Coverity #1317207
|
|
When starting a transient service, allow setting stdin/stdout/stderr fds
for it, by passing them in via the bus.
This also simplifies some of the serialization code for units.

Previously, we'd allocate the TTY, spawn a service on it, but
immediately start processing the TTY and forwarding it to whatever the
commnd was started on. This is however problematic, as the TTY might get
actually opened only much later by the service. We'll hence first get
EIOs on the master as the other side is still closed, and hence
considered it hung up and terminated the session.
With this change we add a flag to the pty forwarding logic:
PTY_FORWARD_IGNORE_INITIAL_VHANGUP. If set, we'll ignore all hangups
(i.e. EIOs) on the master PTY until the first byte is successfully read.
From that point on we consider a hangup/EIO a regular connection termination. This
way, we handle the race: when we get EIO initially we'll ignore it,
until the connection is properly set up, at which time we start
honouring it.
|
|
The child process is shortliving, hence always set O_NOCTTY so that the
tty doesn't quickly become controlling TTY and then gives it up again.
Also set O_CLOEXEC, because it's cleaner, and doesn't affect the parent
anyway.

Fix env expansion

The way to escape a literal dollar sign is to write "$$". But this does
not work right if it's at the beginning of the argument. Fix it.

Regardless of whether we're going to spawn a crash shell or not, let the
kernel reap zombies. It's more consistent this way.
|
|
Instead of freezing in PID1 and letting the forked child freeze or
reboot when exec("/bin/sh") fails, just wait for the child's
exit and then do the freeze_or_reboot in PID1 as usual.
This means that when both crash_shell and crash_reboot are enabled, the
system will reboot after the shell exits.

"data" is always NULL (and unused) in config_parse_crash_chvt().
