Fix endless loops in journalctl --list-boots (closes #617).

non-btrfs file systems (#3117)
Fixes: #2060
(Of course, in the long run, we should probably add a copy-based fall-back. But
given how slow that is, this probably requires some asynchronous forking logic
like the CopyFrom() and CopyTo() method calls already implement.)

The "resources" error is really just the generic error we return when
we hit some kind of error and we have no more appropriate error for the case to
return, for example because of some OS error.
Hence, reword the explanation and don't claim any relation to resource limits.
Admittedly, the "resources" service error is a bit of a misnomer, but I figure
it's kind of API now.
Fixes: #2716

Early in journal_file_set_offline() f->header->state is tested to see if
it's != STATE_ONLINE, and since there's no need to do anything if the
journal isn't online, the function simply returned here.
Since moving part of the offlining process to a separate thread, there
are two problems here:
1. We can't simply check f->header->state, because if there is an
offline thread active it may modify f->header->state.
2. Even if the journal is deemed offline, the thread responsible may
still need joining, so a bare return may leak the thread's resources
like its stack.
To address #1, the helper journal_file_is_offlining() is called prior to
accessing f->header->state.
If journal_file_is_offlining() returns true, f->header->state isn't even
checked, because an offlining journal is obviously online, and we'll
just continue with the normal set offline code path.
If journal_file_is_offlining() returns false, then it's safe to check
f->header->state, because the offline_state is beyond the point of
modifying f->header->state, and there's a memory barrier in the helper.
If we find f->header->state is != STATE_ONLINE, then we call the
idempotent journal_file_set_offline_thread_join() on the way out of the
function, to join a potential lingering offline thread.

When appending to a journal file, journald will:
a) first, append the actual entry to the end of the journal file
b) second, add an offset reference to it to the global entry array stored at
the beginning of the file
c) third, add offset references to it to the per-field entry array stored at
various places of the file
The global entry array, maintained by b) is used when iterating through the
journal without matches applied.
The per-field entry array maintained by c) is used when iterating through the
journal with a match for that specific field applied.
In the wild, there are journal files where a) and b) were completed, but c)
was not before the files were abandoned. This means, that in some cases log
entries are at the end of these files that appear in the global entry array,
but not in the per-field entry array of the _BOOT_ID= field. Now, the
"journalctl --list-boots" command alternatingly uses the global entry array
and the per-field entry array of the _BOOT_ID= field. It seeks to the last
entry of a specific _BOOT_ID=field by having the right match installed, and
then jumps to the next following entry with no match installed anymore, under
the assumption this would bring it to the next boot ID. However, if the
per-field entry wasn't written fully, it might actually turn out that the
global entry array might know one more entry with the same _BOOT_ID, thus
resulting in a indefinite loop around the same _BOOT_ID.
This patch fixes that, by updating the boot search logic to always continue
reading entries until the boot ID actually changed from the previous. Thus, the
per-field entry array is used as quick jump index (i.e. as an optimization),
but not trusted otherwise. Only the global entry array is trusted.
This replaces PR #1904, which is actually very similar to this one. However,
this one actually reads the boot ID directly from the entry header, and doesn't
try to read it at all until the read pointer is actually really located on the
first item to read.
Fixes: #617
Replaces: #1904

Show the various timestamps in hexadecimal too. This is useful for matching the
timestamps included in cursor strings (which are encoded in hex, too), with the
references in the journal header.

* sd-netlink: permit RTM_DELLINK messages with no ifindex
This is useful for removing network interfaces by name.
* nspawn: explicitly remove veth links we created after use
Sometimes the kernel keeps veth links pinned after the namespace they have been
joined to died. Let's hence explicitly remove veth links after use.
Fixes: #2173

Drop the "read_realtime" parameter. Getting the realtime timestamp from an
entry is cheap, as it is a normal header field, hence let's just get this
unconditionally, and simplify our code a bit.
|
|
Let's store the reference as simple sd_id128_t, since we don't actually need a
BootId for it.

systemd-run: fix --slice= in conjunction with --scope
|

source->size < source->filled (#3086)
While the function journal-remote-parse.c:get_line() enforces an assertion that source->filled <= source->size, in function journal-remote-parse.c:process_source() there is a chance that source->size will be decreased to a lower value than source->filled, when source->buf is reallocated. Therefore a check is added that ensures that source->buf is reallocated only when source->filled is smaller than target / 2.

Let's be more careful when setting up the Slice= property of transient units:
let's use manager_load_unit_prepare() instead of manager_load_unit(), so that
the load queue isn't dispatched right away, because our own transient unit is
in it, and we don#t want to have it loaded until we finished initializing it.

This moves the O_TMPFILE handling from the coredumping code into common library
code, and generalizes it as open_tmpfile_linkable() + link_tmpfile(). The
existing open_tmpfile() function (which creates an unlinked temporary file that
cannot be linked into the fs) is renamed to open_tmpfile_unlinkable(), to make
the distinction clear. Thus, code may now choose between:
a) open_tmpfile_linkable() + link_tmpfile()
b) open_tmpfile_unlinkable()
Depending on whether they want a file that may be linked back into the fs later
on or not.
In a later commit we should probably convert fopen_temporary() to make use of
open_tmpfile_linkable().

Before we invoke now(CLOCK_BOOTTIME), let's make sure we actually have that
clock, since now() will otherwise hit an assert.
Specifically, let's refuse CLOCK_BOOTTIME early in sd-event if the kernel
doesn't actually support it.

As discussed here:
https://github.com/systemd/systemd/issues/2619#issuecomment-184670042
Explicitly syncing /etc/machine-id after writing it, is probably a good idea,
since it has a strong "commit" character and is generally a one-time thing.
Fixes #2619.

Previously we'd have generally useful sd-bus utilities in bust-util.h,
intermixed with code that is specifically for writing clients for PID 1,
wrapping job and unit handling. Let's split the latter out and move it into
bus-unit-util.c, to make the sources a bit short and easier to grok.

Make this an output flag instead, so that our function prototypes can lose one

This ports over machinectl and loginctl to also use the new GetProcesses() bus
call to show the process tree of a container or login session. This is similar
to how systemctl already has been ported over in a previous commit.

available in the kernel
|
|
This adds a new GetProcesses() bus call to the Unit object which returns an
array consisting of all PIDs, their process names, as well as their full cgroup
paths. This is then used by "systemctl status" to show the per-unit process
tree.
This has the benefit that the client-side no longer needs to access the
cgroupfs directly to show the process tree of a unit. Instead, it now uses this
new API, which means it also works if -H or -M are used correctly, as the
information from the specific host is used, and not the one from the local
system.

Nicer error message is symlinking chokes on an existing file
|
|
|
|
Before:
$ systemctl preset getty@.service
Failed to preset unit, file /etc/systemd/system/getty.target.wants/getty@tty1.service
already exists and is a symlink to ../../../../usr/lib/systemd/system/getty@.service.
After:
$ systemctl preset getty@.service
Created symlink /etc/systemd/system/getty.target.wants/getty@tty1.service,
pointing to /usr/lib/systemd/system/getty@.service.
We don't really care where the symlink points to. For example, it might point
to /usr/lib or /etc, and systemd will always load the unit from /etc in
preference to /usr/lib. In fact, if we make a symlink like
/etc/systemd/system/multi-user.target.wants/b.service -> ../a.service, pid1
will still start b.service. The name of the symlink is the only thing that
matters, as far as systemd is concerned. For humans it's confusing when the
symlinks points to anything else than the actual unit file. At the very least,
the symlink is supposed to point to a file with the same name in some other
directory. Since we don't care where the symlink points, we can always replace
an existing symlink.
Another option I considered would be to simply leave an existing symlink in
place. That would work too, but replacing the symlink with the expected value
seems more intuitive.
Of course those considerations only apply to .wants and .requires. Symlinks
created with "link" and "alias" are a separate matter.
Fixes #3056.

When "preset" was executed for a unit without install info, we'd warn similarly
as for "enable" and "disable". But "preset" is usually called for all units,
because the preset files are provided by the distribution, and the units are under
control of individual programs, and it's reasonable to call "preset" for all units
rather then try to do it only for the ones that can be installed.
We also don't warn about missing info for "preset-all". Thus it seems reasonable
to silently ignore units w/o install info when presetting.
(In addition, when more than one unit was specified, we'd issue the warning
only if none of them had install info. But this is probably something to fix
for enable/disable too.)

path_kill_slashes was applied to the wrong arg...
|
|
|
|
Fixes #1892.
Previously:
Failed to enable unit: Invalid argument
Now:
Failed to enable unit, file /etc/systemd/system/ssh.service already exists.
It would be nice to include the unit name in the message too. I looked into
this, but it would require major surgery on the whole installation logic,
because we first create a list of things to change, and then try to apply them
in a loop. To transfer the knowledge which unit was the source of each change,
the data structures would have to be extended to carry the unit name over into
the second loop. So I'm skipping this for now.

We enable lingering for anyone who wants this. It is still disabled by
default to avoid keeping long-running processes accidentally.
Admins might want to customize this policy on multi-user sites.
|
|
Instead of KillOnlyUsers being a filter for KillUserProcesses, it can now be
used to specify users to kill, independently of the KillUserProcesses
setting. Having the settings orthogonal seems to make more sense. It also
makes KillOnlyUsers symmetrical to KillExcludeUsers.
