Some events take longer than the default 30 seconds. Killing those
events will leave the machine halfway configured.
Add a commandline option '--event-timeout' to handle these cases.

Avoid using msecs in favor of usec_t. This is more consistent with the
other parts of systemd and avoids the confusion between msec and usec. We
always use usecs, end of story.
|
|
Avoid hard-coding "unsigned long" and use the usec_t type defined in
src/shared.

This partially implements RFC3203. Note that we are not fully compliant as we do not
support authentication.

This is necessary in order to listen for FORCERENEW events.

This allows the sockets to be bound to a specific address before it is configured,
also enable SO_REUSEADDR to allow multiple DHCP clients to run at the same time.
|

Keep this internal to the client and simply restart it when NAK is receieved, as
per the RFC.

RAW messages are verified by the BPF in the kernel.

Set SYSLOG_FACILITY field for kernel log messages too. Setting only
SYSLOG_IDENTIFIER="kernel" is not sufficient and tools reading journal
maybe confused by missing SYSLOG_FACILITY field for kernel log messages.

This fixes the issue noted by Zbigniew in most cases.
if a unit's name is enclosed in single quotes completion still
will not happen after the first `\'.

At least
t->ignore = f->ignore;
is missing here. Just copy the full struct to be sure.

Require exact matches in all cases instead of treating strings
starting with 't' ('f') as true (false).
This is required for config_parse_protect_system to parse ProtectSystem=full
correctly: it uses parse_boolean and only tries a more specific parsing
function if that did not return a valid result. Thus "full" was treated as
"false" before.

Single PAM fallback config file to be used in /etc to allow

We can not reliably manage any notion of local time. Every daylight
saving time change or time zone change by traveling will make the
time jump, and the local time might jump backwards which creates
unsolvable problems with file timestamps.
We will no longer tell the kernel our local time zone and leave
everything set to UTC. This will effectively turn FAT timestamps
into UTC timestamps.
If and only if the machine is configured to read the RTC in local
time mode, the kernel's time zone will be configured, but
systemd-timesysnc will disable the kernel's system time to RTC
syncing. In this mode, the RTC will not be managed, and external
tools like Windows bootups are expected to manage the RTC's time.

I think that it is better to return good results slightly more slowly,
than partial quickly. Also reading from disk seems fast enough. Even
the delay on first try with completely cold cache is acceptable.
This is just for bash, 'cause zsh was already doing this.

This makes it easier to debug what is going on.

People might be confused where the file comes from, since the name is not
at all specific.

We will abort anyway.

We need to check if argv[1] is set before compare
|
|
There is a small number of the places in sources where we don't check
asprintf() return code and assume that after error the function
returns NULL pointer via the first argument. That's wrong, after
error the content of pointer is undefined.

Units with literal hex '\xFF' in their names has to be read

Without this, secondary addresses would get deleted when the primary one is. This is not
the desired behavior when one would like to transition from one address to another in the
same subnet (such as when a new IP address is given over DHCP).
In networkd, when given a new IP over DHCP we will add it, without explicitly removing the
old one first (and hence never have a window without an IP address configured). Assuming the
addresses are in the same subnet, that means that the old address is the primary and the new
address is the secondary one. Once the old address expires, the kernel will drop it. With the
old behavior this means that both addresses would be lost, which is clearly not what we want.
With the new behavior, only the old address is lost, and the new one is promoted to primary.

Err can't be bigger then zero. Rest of the code uses negative Exxxx values.

This is necessary for non-ipv4ll hosts to communicate with ipv4ll-only hosts on the same link. Defaults
to being enabled, but can be opted out.

MD instantiates devices at open(). This is incomptible with the
locking logic, as the "change" event emitted when stopping a
device will bring it back.

The timeouts in the networking library (DHCP lease timeouts and similar) should not be affected
by suspend. In the cases where CLOCK_BOOTTIME is not implemented, it is still safe to fallback to
CLOCK_MONOTONIC, as the consumers of the library (i.e., networkd) _should_ renew the leases when
coming out of suspend.
|
|
CLOCK_BOOTTIME is not supported by timerfd on older kernels, so for the time beeing,
use this helper instead which will fallback to CLOCK_MONOTONIC if CLOCK_BOOTTIME is
not supported.
|
|
This requires a very recent kernel (3.15), so care should be taken
when using this functionality.
|
|
This avoids having to distinguish between IPv4 and IPv6, allowing us
to keep their internal orderings. The consumers now has to turn the
strings into addresses.
|
|
networkd will expose both statically configured DNS servers and servers
receieved over DHCP in sd_network_get_dns(), so no need to keep
the distinction in resolved.
|
|
In the state files, do not distinguish where the various entries came from
(static or DHCP), but include them all in the same list.
|
|
|
|
|
|
Probably a left-over from when router solicitations were
requested in the DHCP6 code. But since they are now separate,
this state is no longer needed.
|
|
All routes added by networkd are currently set RTPROT_BOOT, which according
to the kernel means "Route installed during boot" (rtnetlink.h). But this
is not always the case as networkd changes routing after boot too. Since
the kernel gives more detailed protocols, use them.
With this patch, user-configured static routes now use RTPROT_STATIC (which
they are) and DHCP routes use RTPROT_DHCP. There is no define for IPv4LL
yet, so those are installed as RTPROT_STATIC (though perhaps RTPROT_RA is
better?).
