Implement a maximum limit on number of journal files to keep around.
Enforcing a limit is useful on this since our performance when viewing
pays a heavy penalty for each journal file to interleve. This setting is
turned on now by default, and set to 100.
Also, actully implement what 348ced909724a1331b85d57aede80a102a00e428
promised: use whatever we find on disk at startup as lower bound on how
much disk space we can use. That commit introduced some provisions to
implement this, but actually never did.
This also adds "journalctl --vacuum-files=" to vacuum files on disk by
their number explicitly.

Indicate that we are ignoring errors, when we ignore them, and log that
at LOG_WARNING level.
Use the right error code for the log message.

Let's try to use O_NOATIME if we can when vacuuming old journal files,
if we have the permissions for it, so that vacuuming doesn't count as
proper journal read access.
|
|
|
|
The way it is customary everywhere else in our sources.
|
|
Let's use fd_getcrtime_at(), since that *at() family of calls is how we
read the rest of the file metadata, too.
|
|
That way, we don't ever open the file, thus leave the atime untouched,
and this works even when unprivileged.

An rfkill rework among other things

journald: add syslog fields for driver messages
|
|
|
|
With this rework we introduce systemd-rfkill.service as singleton that
is activated via systemd-rfkill.socket that listens on /dev/rfkill. That
way, we get notified each time a new rfkill device shows up or changes
state, in which case we restore and save its current setting to disk.
This is nicer than the previous logic, as this means we save/restore
state even of rfkill devices that are around only intermittently, and
save/restore the state even if the system is shutdown abruptly instead
of cleanly.
This implements what I suggested in #1019 and obsoletes it.

Writable= is a new boolean setting. If ture, then ListenSpecial= will
open the specified path in O_RDWR mode, rather than just O_RDONLY.
This is useful for implementing services like rfkill, where /dev/rfkill
is more useful when opened in write mode, if we want to not only save
but also restore its state.

There was a bad memory access among other smaller issues.

tree-wide: add missing errno arguments to log_*_errno()

Use %m where previously %s was used together with strerrno().

This commit fixes Coverity #1325228

A few of the recent conversions to log_*_errno() were missing the errno
value arguments.

This makes sure libmicrohttpd won't call shutdown() on our listening
sockets, which make sure socket activation and re-activation will work
cleanly.

In cases where we use for instance. log_debug() with a statement + string
it is better to output (Service-name: N/A) instead of (Service-name: )

Let's clean up our tree a bit, and reduce invocations of the
thread-unsafe strerror() by replacing it with printf()'s %m specifier.
|
|
|
|
Let's unify more code.
Also, rework the macro to accept a trailing semicolon, to make the code
prettier.
|
|
extract_first() already skips trailing whitespace, hence no reason to
explicitly check for it.
|
|
It's pretty untypical for our parsing functions to log on their own.
Clarify in the name that this one does.
|
|
Also, make sure it follows the same scheme as log_syntax() does in its
behaviour.
|

- Rely everywhere that we use abs() on the error code passed in anyway,
thus don't need to explicitly negate what we pass in
- Never attach synthetic error number information to log messages. Only
log about errors we *receive* with the error number we got there,
don't log any synthetic error, that don#t even propagate, but just eat
up.
- Be more careful with attaching exactly the error we get, instead of
errno or unrelated errors randomly.
- Fix one occasion where the error number and line number got swapped.
- Make sure we never tape over OOM issues, or inability to resolve
specifiers

journalctl: add --rotate option

We need to prevent the creation of the gpt automount unit, which will not
get overridden by the fstab mount unit.

mq_getattr returns -1/EBADF for file descriptors which are not mq.
But we should return 0 in this case.
We first check that fd is a valid fd, so we can assume that if
mq_getattr returns EBADF, it is simply a non-mq fd. There is a slight
race, but there doesn't seem to be a nice way to fix it.
