The characters are already checked, so we show that
we don't trust the kernel. Make sure we don't overrun
the buffer too.

Let's do the wake-up logic on NFS internally, making things simpler for
users.

We don't need this right now, but we should keep our options open, in
case we need more than just an fd for waking up.

The password query for a crypto device currently times out after 90s,
which is too short to grab a cup of coffee when a machine boots up.
The resulting decrypted device /dev/mapper/luks-<uuid> might not
be a mountpoint (but part of a LVM PV or raid array)
and therefore the timeout cannot be controlled by the settings
in /etc/fstab. For this reason this device should not carry its own timeout.
Also the encrypted device /dev/disk/by-*/* already has a timeout and
additionally the timeout for the password query is set in /etc/crypttab.
This patch disables the timeout of the resulting decrypted devices by creating
<device-unit>.d/50-job-timeout-sec-0.conf files with "JobTimeoutSec=0".

flags to wait for
We should keep our options open, so that we can watch for POLLOUT later
on if we wish to. CUrrently this call will always return POLLIN however.
|
|
This function should be used when filling in "struct pollfd"'s .events
field for watching the journal. It will always return POLLIN for now,
but we should keep our options open to change this later on.
This mimics libsystemd-bus' sd_bus_get_events() call with the same
purpose.

Make sure to always print out at least one valid component instead of
falling back early to 0.

Instead of outputting "5h 55s 50ms 3us" we'll now output "5h
55.050003s". Also, while outputting the accuracy is configurable.
Basically we now try use "dot notation" for all time values > 1min. For
>= 1s we use 's' as unit, otherwise for >= 1ms we use 'ms' as unit, and
finally 'us'.
This should give reasonably values in most cases.
|
|
We can now parse "0.5s" as the same as "500ms". In fact, we can parse
"3.45years" correctly, too, and any other unit and fraction length.

internet hostname unset the pretty name
If people are unaware or uninterested in the concept of pretty host
names, and simply invoke "hostnamectl set-hostname" for a valid internet
host name, then use this as indication to unset the pretty host name and
only set the static/dynamic one.
This also allows fqdn, hence "hostnamectl set-hostname www.foobar.com"
will just work if people really insist on using fqdns as hostnames.

This will properly escape all weird chars when writing env var files.
With this in place we can now read and write environment files where the
values contain arbitrary weird chars.
This enables hostnamed and suchlike to finally properly save pretty host
names with backlashes or quotes in them.
|
|
Implement this with a proper state machine, so that newlines and
escaped chars can appear in string assignments. This should bring the
parser much closer to shell.
|
|
Internally we store all time values in usec_t, however parse_usec()
actually was used mostly to parse values in seconds (unless explicit
units were specified to define a different unit). Hence, be clear about
this and name the function about what we pass into it, not what we get
out of it.
|
|
You can write much more than just one line with this call (and we
frequently do), so let's correct the naming.

mss-myhostname wasn't working because of underlinking. Instead of
fixing the underlinking, just remove the use of _cleanup_ macros.
It is impolite to use our utility functions in modules designed to be
loaded by others. So cleanup macros which (at some point) call assert
which calls log_assert_failed, should not be used. Revert this part of
commit d73c3269c.

This patch changes local-fs.target and systemd-fsck to not use
"isolate" when going into emergency.
This fixes https://bugzilla.redhat.com/show_bug.cgi?id=810722
The motivation is, that when something wents wrong, we should
keep everything as it is, to let the user fix the problem. When
isolating we stop a lot of services and therefore change the
system heavily so that it gets harder for the user to fix.
An example is a crypted partition. When the fsck in a crypted
partition fails, it previously used "emergency/start/isolate"
which stops cryptsetup. Therefore if the user tries to fsck
e.g. /dev/mapper/luks-356c20ae-c7a2-4f1c-ae1d-1d290a91b691
as printed by the failing fsck, then it will not find this
device (because it got closed).
So please apply this patch to let the user see the failing
situation.
Thanks!
[zj: removed dead isolate param from start_target().]

code in src/shared/macro.h only defined MAX/MIN in case
they were not defined previously. however the MAX/MIN
macros implemented in glibc are not of the "safe" kind but defined
as:
define MIN(a,b) (((a)<(b))?(a):(b))
define MAX(a,b) (((a)>(b))?(a):(b))
Avoid nasty side effects by using our own versions instead.
Also fix the warnings derived from this change.
[zj: - modify MAX3 macro to fix warning about _a shadowing _a,
- do bootchart/svg.c too,
- remove unused MIN3.]

Previously we simply counted how many processes we killed and expected
as many waitpid() calls to succeed. That however is incorrect to do.
As we might kill processes that are not our immediate children, and as
there might be left-over processes in the waitpid() queue from earlier
the we might get more ore less waitpid() events that we expect.
Hence: keep precise track of the processes we kill, remove the ones we
get waitpid() for, and after each time we get SIGCHLD check if all
others still exist. We use getpgid() to check if a PID still exists.
This should fix issues with journald not setting journal files offline
correctly on shutdown, because we'd too quickly proceed from SIGTERM to
SIGKILL because some left-over process was in our waitpid() queue.

This ensures that the keyfile is available during the opening of the encrypted
device.
Also dropped the explicit ordering Before=local-fs.target, as the containers
are ordered implicitly by their content.

When showing an error like 'Socket service not loaded', the
error won't show up in the status for the socket, unless it is
marked as SYSTEMD_UNIT=*.socket. Marking it as SYSTEMD_UNIT=*.service,
when the service is non-existent, is not useful.

As it turns out SCM_CREDENTIALS is not always supported on socketpair(),
so let's also try SO_PEERCRED then.
