Let's move DUID configuration into the [DHCP] section, since it only makes
sense in a DHCP context, and should be close to the configuration of
ClientIdentifier= and suchlike.
This really shouldn't be a section of its own, we don't have any for any of our
other per-protocol specific identifiers...
Follow-up for #2890 #2943

Various small cleanups in shared code
|
|
Now we are not setting static address, start dhcp6 client and
discovering IPv6 routers after link gained carrier.
This fixes #2912.
|
|
|
|
It make more sense to initalize the node first then
we add to the list.
|
|
We are not able to add multiple properties.
wlp3s0.network:
[Match]
Name=wlp3s0
[Route]
Gateway=10.68.5.26
Metric=10
sudo ./systemd-networkd
Failed to parse file '/usr/lib/systemd/network/wlp3s0.network': File
exists
Could not load configuration files: File exists
This patch fixes it.

If we not marking manager dirty when link is dirty then
the state file is not updated. This is a side effect of
issue 2850
setting CriticalConnection=yes
timesyncd NTP servers given by DHCP server are ignored.

This fixes #2282.

IPv6 protocol requires a minimum MTU of 1280 bytes on the interface.
This fixes #3046.
Introduce helper link_ipv6_enabled() to figure out whether IPV6 is enabled.
Introduce network_has_static_ipv6_addresses() to find out if any static
ipv6 address configured.
If IPv6 is not configured on any interface that is SLAAC, DHCPv6 and static
IPv6 addresses not configured, then IPv6 will be automatically disabled for that
interface, that is we write "1" to /proc/sys/net/ipv6/conf//disable_ipv6.

Fixes: #2889
|
|
We only use it for the Tx code anyway, hence sd-lldp.h shouldn't expose it, as
it only implements Rx.
|
|
Let's properly handle hashmap_put() failing.

Replace if with assert_cc in lldp code and a build-sys tweak
|
|
DHCP DUID parsing fix, logging fix, man-page fix
|
|
LLDP_TX_HOLD or one of the other variables might be changed in the future
resulting in a silent error here if the if was just removed.
Replacement for #2983.
|
|
1. Replace strtol with unhexchar, verified with valid and invalid DUID strings.
2. Fix logging to use log_syntax instead of log_error.
3. On error reading DUID, ignore read and preserve previous state.
4. Fix man-pages to use markup, remove options not yet implemented.
5. Remove spurious header line in new files.
|
|
For #2915.

lldp.h contains definitions of LLDP types, subtypes and capabilities which
should be exposed in public headers. Get rid of the file and move those
definitions to sd-lldp.h with the SD_ prefix.

Enable more tests by default, and even more with `--enable-tests=unsafe`

name is IFNAMSIZ bytes, but we would copy sizeof(info->name) bytes,
which is IFNAMSIZ + 1. In effect we would go outside of the source
buffer and possibly leave a non-null terminated string in info->name.

tree-wide: merge pager_open_if_enabled() to the pager_open()
|
|
Many subsystems define own pager_open_if_enabled() function which
checks '--no-pager' command line argument and open pager depends
on its value. All implementations of pager_open_if_enabled() are
the same. Let's merger this function with pager_open() from the
shared/pager.c and remove pager_open_if_enabled() from all subsytems
to prevent code duplication.

tree-wide: minor formatting inconsistency cleanups

Networkctl prettification

|
|
Throughout the tree there's spurious use of spaces separating ++ and --
operators from their respective operands. Make ++ and -- operator
consistent with the majority of existing uses; discard the spaces.

networkd: tunnel fix tunnel address

See: #2683

Instead of just notifying about the fact that something changed in the
database, actually inform the callback what precisely changed. This is useful,
so that the LLDP tx logic can be put into "fast" mode as soon as a previously
unknown peer appears, as suggested by the LLDP spec.
|
|
|
|
|
|
Let's add some minimalistic LLDP sender support. The idea is that this is
either on or off, and all fields determined automatically rather than
configured explicitly.
|
|
Let's not get confused should we be connected to some bridge that mirrors back
our packets.
|
|
These functions are nowadays used only within networkd-link.c, hence ther's no
point in littering our public namespace with them.
|
|
Being on the link-layer LLDP is nothing we should turn on only when there's a
link beat. Instead, turn it on, whenever the iface is UP regardless if there's
a link beat or not. This closes the race between a link beat being available
and us subscribing to LLDP as a result.
|
|
|
|
After all, if we know that an interface exists but networkd did not store any
info about it, then it's definitely unmanaged by it.
(Note that we add this fix-up to networkctl, and not to sd-network, simply
because a missing file might also be result of the interface not existing.)
