Given that we now have KillMode=mixed where SIGTERM might kill a smaller
set than SIGKILL we need to make sure to always go explicitly throught
the SIGKILL state to get the right end result.

process, but SIGKILL to all daemon processes
This should fix some race with terminating systemd --user, where the
system systemd instance might race against the user systemd instance
when sending SIGTERM.

(The kernel module got fixed, so let's reenable this again)

We'd reqeue the next status update very soon after. Change it so that we wait
for full 5s without any job status changes until we print anything.

This reverts commit 28c758de94bc8ba97b89d9dab3f517cf466978d0
but makes job_coldplug smarter.
In (v1) I changed the job start timestamp to be always set, so the
start time can be reported in the cylon eye message. The bug was that
when deserializing jobs, they would be ignored if their start
timestamp was unset which was synonymous with no timeout. But after
the change, jobs would have a start timestamp set despite having no
timeout. After deserialization they would be considered immediately
expired. Fix this by checking if the timeout is not zero when
considering jobs for expiration.

It is nice to wrap umask handling and return convention,
but glibc's mkostemp is async-signal-safe already.
|
|
Current glibc implementation is safe. Kernel does this atomically,
and write is actually implemented through writev. So if write is
async-signal-safe, than writev pretty much must be too.
|
|
Let's unify our code here, and also always specifiy O_CLOEXEC.
|
|
|
|
On other archs we'll not define it so that open_tmpfile() falls back to
unguessable name + unlink.
|
|
|
|
Make it use dev_urandom() and endswith().
|
|
doesn't fall back to PRNG
|
|
Let's make use of fd_wait_for_event() here, instead of rolling our own.

This reverts commit 2cba2e03524ec0922ddc70f933e8a89b7d23b4ec.
It breaks bootup with dracut, the transition to the real rootfs fails.

When set to auto, status will shown when the first ephemeral message
is shown (a job has been running for five seconds). Then until the
boot or shutdown ends, status messages will be shown.
No indication about the switch is done: I think it should be clear
for the user that first the cylon eye and the ephemeral messages appear,
and afterwards messages are displayed.
The initial arming of the event source was still wrong, but now should
really be fixed.

signal(7) provides a list of functions which may be called from a
signal handler. Other functions, which only call those functions and
don't access global memory and are reentrant are also safe.
sd_j_sendv was mostly OK, but would call mkostemp and writev in a
fallback path, which are unsafe.
Being able to call sd_j_sendv in a async-signal-safe way is important
because it allows it be used in signal handlers.
Safety is achieved by replacing mkostemp with open(O_TMPFILE) and an
open-coded writev replacement which uses write. Unfortunately,
O_TMPFILE is only available on kernels >= 3.11. When O_TMPFILE is
unavailable, an open-coded mkostemp is used.

This will only work on Linux >= 3.11, and probably not on all
filesystems. Fallback code is provided.

sizes and numbers of hash functions
In order to make the bloom filter logic more future proof communicate
bloom filter parameters from the original bus creator to the clients,
and allow them to be variable within certain ranges.
|

Add new calls sd_bus_open() and sd_bus_default() for connecting to the
starter bus a service was invoked for, or -- if the process is not a
bus-activated service -- the appropriate bus for the scope the process
has been started in.

We know that launching a unit will fail if some required directories
haven't been mounted yet. There's no point in starting it just to
have it fail even before it gets a chance to run.
|
|
Just a microopt.

It would fire just once.
Also fix units from sec to usec as appropriate.
Decrease the switching interval to 1/3 s, so that when the time
remaining is displayed with 1s precision, it doesn't jump by 2s every
once in a while. Also, the system is feels noticably faster when the
status changes couple of times per second instead of every few
seconds.

Produces output like:
[ *** ] (1 of 2) A start job is running for slow.service (33s / 1min 30s)
The first nubmer is the time since job start, the second is the job timeout.
|
|
Things will continue when either the job timeout
or the unit timeout is reached. Add functionality to
access that info.

Debian recently introduced the option key-slot to /etc/crypttab to
specify the LUKS key slot to be used for decrypting the device. On
systems where a keyfile is used and the key is not in the first slot,
this can speed up the boot process quite a bit, since cryptsetup does
not need to try all of the slots sequentially. (Unsuccessfully testing
a key slot typically takes up to about 1 second.)
This patch makes systemd aware of this option.

Compat stuff is moved to src/compat-libs/.
Warnings are issued when programs are linked with the deprecated library.
|
|
A compatibility libsystemd-login library is created which uses
.symver and ifunc magic proposed by Lennart to make programs linked
to the old library name continue to work seamlessly.
Unfortunately the bfd linker crashes:
https://sourceware.org/bugzilla/show_bug.cgi?id=16467
This will be fixed in binutils 2.25.
As a work-around, gold can be used:
LDFLAGS=-Wl,-fuse-ld=gold
Unfortunately the switch to pick the linker appeared in gcc 4.8.
This also doesn't work with LLVM:

Fix/add some structured logging messages, and be uniform about when we WARN and ERR.
|
|
|
|
|
|
Also insist on messages being sealed before reading them. In other
words we don't allow interleaving of reading and appending to messages.
