The time-util.c provides dual_timestamp_get() function for getting
realtime and monotonic timestamps. Let's use it instead of direct
realtime/monotonic calculation.
Instead of discarding duplicate catalog entries, we now combine
them. This allows software or admins to add or override catalog
headers, or add additional text to the catalog message.
Set the MHD_OPTION_CONNECTION_MEMORY_LIMIT to 128KB. The precious value was DATA_SIZE_MAX, which was defined as 1024*1024*768. This caused journal-remote to allocate 756MB for each journal-upload connection, thus exhausting the available memory.
Let's use bitfields for our booleans, and don't try to apply binary OR or addition on them, because that's weird and we
should instead use logical OR only.
We really shouldn't fail silently, but print a log message about these errors. Also make sure to attach error codes to
all log messages where that makes sense.
(While we are at it, add a couple of (void) casts to functions where we knowingly ignore return values.)
This makes sure we never run two control processes at the same time, we cannot keep track off.
This introduces a slight change of behaviour but cleans up the definition of ExecStop= and ExecStopPost=. The former is
now invoked only if the service managed to start-up correctly. The latter is called even if start-up failed half-way.
Thus, ExecStopPost= may be used as clean-up step for both successful and failed start-up attempts, but ExecStop='s
purpose is clearly defined as being responsible for shutting down the service and nothing else.
The precise behaviour of this was not documented yet. This commit adds the necessary docs.
Fixes: #1254
Let's make sure we don't choke if blkid_probe_lookup_value() returns a NULL string.
Also, make sur we propagate the correct error when blkid_probe_lookup_value() fails.
This adds a new switch --as-pid2, which allows running commands as PID 2, while a stub init process is run as PID 1.
This is useful in order to run arbitrary commands in a container, as PID1's semantics are different from all other
processes regarding reaping of unknown children or signal handling.
For use in timesyncd we already defined a compile-time "epoch" value, which is based on the mtime of the NEWS file, and
specifies a point in time we know lies in the past at runtime. timesyncd uses this to filter out nonsensical timestamp
file data, and bump the system clock to a time that is after the build time of systemd. This patch adds similar bumping
code to earliest PID 1 initialization, so that the system never continues operation with a clock that is in the 1970ies
or even 1930s.
systemd-logind uses mkdir_label and label_fix functions without calling
first mac_selinux_init. This makes /run/user/$UID/ directories not
labelled correctly on an Arch Linux system using SELinux.
Fix this by calling mac_selinux_init("/run") early in systemd-logind.
This makes files created in /etc/udev/rules.d and /var/lib/systemd to be
labelled through transitions in the SELinux policy instead of using
setfscreatecon (with mac_selinux_create_file_prepare).
The mount_setup_early() and mount_setup() contain almost the same
pieces of code which calls mount_one() for a certain mount point
from the mount_table. This patch introduces mount_points_setup()
helper to prevent code duplication.
Currently when journalctl is called with path to block device node we
add following match _KERNEL_DEVICE=b$MAJOR:$MINOR.
That is not sufficient to actually obtain logs about the disk because
dev_printk() kernel helper puts to /dev/kmsg information about the
device in following format, +$SUBSYSTEM:$ADDRESS,
e.g. "+pci:pci:0000:00:14.0".
Now we will walk upward the syspath and add match for every device in
format produced by dev_printk() as well as match for its device node if
it exists.
The server might answer to a DHCPREQUEST with a NAK and currently the
client restarts the configuration process immediately. It was
observed that this can easily generate loops in which the network is
flooded with DISCOVER,OFFER,REQUEST,NAK sequences.
RFC 2131 only states that "if the client receives a DHCPNAK message,
the client restarts the configuration process" without further
details.
Add a delay with exponential backoff between retries after NAKs to
limit the number of requests and cap the delay to 30 minutes.
