Failed to open /var/log/journal/33f46101703a10c5fc6fa4f451840101/fss.tmp.k2wDDU: No such file or directory
Corrupted empty files are relatively common. I think they are created
when a coredump for a user who never logged anything before is
attempted to be written, but the write does not succeed because the
coredump is too big, but there are probably other ways to create
those, especially if the machine crashes at the right time.
Non-corrupted empty files can also happen, e.g. if a journal file is
opened, but nothing is ever successfully written to it and it is
rotated because of MaxFileSec=. Either way, each "empty" journal file
costs around 3 MB, and there's little point in keeping them around.
Reporting of the free space was bogus, since the remaining space
was compared with the maximum allowed, instead of the current
use being compared with the maximum allowed. Simplify and fix
by reporting limits directly at the point where they are calculated.
Also, assign a UUID to the message.
Sometimes an entry is not successfully written, and we end up with
data items which are "unlinked", not connected to, and not used by any
entry. This will usually happen when we write to write a core dump,
and the initial small data fields are written successfully, but
the huge COREDUMP= field is not written. This situation is hard
to avoid, but the results are mostly harmless. Thus only warn about
unused data items.
Also, be more verbose about why journal files failed verification.
This should help diagnose journal failure modes without resorting
to a hexadecimal editor.

system.journal attached to the bug report).
When journald encounters a message with OBJECT_PID= set
coming from a priviledged process (UID==0), additional fields
will be added to the message:
OBJECT_UID=,
OBJECT_GID=,
OBJECT_COMM=,
OBJECT_EXE=,
OBJECT_CMDLINE=,
OBJECT_AUDIT_SESSION=,
OBJECT_AUDIT_LOGINUID=,
OBJECT_SYSTEMD_CGROUP=,
OBJECT_SYSTEMD_SESSION=,
OBJECT_SYSTEMD_OWNER_UID=,
OBJECT_SYSTEMD_UNIT= or OBJECT_SYSTEMD_USER_UNIT=.
This is for other logging daemons, like setroubleshoot, to be able to
augment their logs with data about the process.

Since the system journal wasn't open yet, available_space() returned 0.
Before:
systemd-journal[22170]: Allowing system journal files to grow to 4.0G.
systemd-journal[22170]: Journal size currently limited to 0B due to SystemKeepFree.
After:
systemd-journal[22178]: Allowing system journal files to grow to 4.0G.
systemd-journal[22178]: Journal size currently limited to 3.0G due to SystemKeepFree.
Also, when failing to write a message, show how much space was needed:
"Failed to write entry (26 items, 260123456 bytes) despite vacuuming, ignoring: ...".
In the following scenario:
server creates system.journal
server creates user-1000.journal
both journals share the same seqnum_id.
Then
server writes to user-1000.journal first,
and server writes to system.journal a bit later,
and everything is fine.
The server then terminates (crash, reboot, rsyslog testing,
whatever), and user-1000.journal has entries which end with
a lower seqnum than system.journal. Now
server is restarted
server opens user-1000.journal and writes entries to it...
BAM! duplicate seqnums for the same seqnum_id.
Now, we usually don't see that happen, because system.journal
is closed last, and opened first. Since usually at least one
message is written during boot and lands in the system.journal,
the seqnum is initialized from it, and is set to a number higher
than than anything found in user journals. Nevertheless, if
system.journal is corrupted and is rotated, it can happen that
an entry is written to the user journal with a seqnum that is
a duplicate with an entry found in the corrupted system.journal~.
When browsing the journal, journalctl can fall into a loop
where it tries to follow the seqnums, and tries to go the
next location by seqnum, and is transported back in time to
to the older duplicate seqnum. There is not way to find
out the maximum seqnum used in a multiple files, without
actually looking at all of them. But we don't want to do
that because it would be slow, and actually it isn't really
possible, because a file might e.g. be temporarily unaccessible.
Fix the problem by using different seqnum series for user
journals. Using the same seqnum series for rotated journals
is still fine, because we know that nothing will write
to the rotated journal anymore.

The order was different in various places, which makes it harder to
read to code. Also consistently use ternany for all direction checks.
Remove one free(NULL).
This allows the caller to explicitly specify which journal files
should be opened. The same functionality could be achieved before
by creating a directory and playing around with symlinks. It
is useful to debug stuff and explore the journal, and has been
requested before.
Waiting is supported, the journal will notice modifications on
the files supplied when opening the journal, but will not add
any new files.
AND term usually don't have many subterms (4 seems to be the maximum
sensible number, e.g. _BOOT_ID && _SYSTEMD_UNIT && _PID && MESSAGE_ID).
Nevertheless, the cost of checking each subterm can be relatively
high, especially when the nested terms are compound, and it
makes sense to minimize the number of checks.
Instead of looping to the end and then again over the whole list once
again after at least one term changed the offset, start the loop at
the term which caused the change. This way ½ terms in the AND match
are not checked unnecessarily again.
--user basically gives messages from your own systemd --user services.
--system basically gives messages from PID 1, kernel, and --system
services. Those two options are not exahustive, because a priviledged
user might be able to see messages from other users, and they will not
be shown with either or both of those flags.
This is the just the library part.
SD_JOURNAL_CURRENT_USER flags is added to sd_j_open(), to open
files from current user.
SD_JOURNAL_SYSTEM_ONLY is renamed to SD_JOURNAL_SYSTEM,
and changed to mean to (also) open system files. This way various
flags can be combined, which gives them nicer semantics, especially
if other ones are added later.
Backwards compatibility is kept, because SD_JOURNAL_SYSTEM_ONLY
is equivalent to SD_JOURNAL_SYSTEM if used alone, and before there
we no other flags.
$ journalctl -o verbose _EXE=/quiet/binary -f

Failed to get realtime timestamp: Cannot assign requested address
JOURNAL_FOREACH_DATA_RETVAL is added, which allows the caller
to get the return value from sd_journal_enumerate_data. I think
we might want to expose this macro like SD_JOURNAL_FOREACH_DATA,
but for now it is in journal-internal.h.
There's a change in behaviour for output_*, not only in
output_verbose, that errors in sd_j_enumerate_data are not silently
ignored anymore.

Also reworded a few debug messages for brevity, and added a log
statement which prints out the filter at debug level:
Journal filter: (((UNIT=sys-module-configfs.device AND _PID=1) OR (COREDUMP_UNIT=sys-module-configfs.device AND MESSAGE_ID=fc2e22bc6ee647b6b90729ab34a250b1) OR _SYSTEMD_UNIT=sys-module-configfs.device) AND _BOOT_ID=4e3c518ab0474c12ac8de7896fe6b154)
Since 11ec7ce, journald isn't setting the ACLs properly anymore if
the files had no ACLs to begin with: acl_set_fd fails with EINVAL.
An ACL with ACL_USER or ACL_GROUP entries but no ACL_MASK entry is
invalid, so make sure a mask exists before trying to set the ACL.
Bump the minimal size of the journal so that we can be sure creating the
journal file will always succeed. Previously the minimum size was
smaller than a empty jounral file...
