We no longer add these. If you use Emacs, configure it yourself.
Also, due to our "smart-tab" usage the editor anyway does a subpar
job handling our tabs. However, on the upside every user can choose
whatever tab-width he/she prefers. If "smart-tabs" are used properly
(like we do), every tab-width will work.
No manual changes, just ran commands:
F=($(git grep -l -e '-\*-'))
sed '1 { /\/\* *-\*- *[mM]ode.*\*\/$/d }' -i "${F[@]}"
sed '1,4 { /^\(#\|--\|dnl\) *-\*- [mM]ode/d }' -i "${F[@]}"
Check remaining lines with:
git grep -e '-\*-'
The ultimate purpose of this is to cleanup our files and eventually use
SPDX license identifiers. For that, first get rid of the boilerplate lines.
While at it, rename the "addr" field to "l_address". The term "addr" is
used over and over. Instead we should use distinct names that make it
easier to navigate the code.
nmtst_get_rand_int() was originally named that way, because it
calls g_rand_int(). But I think if a function returns an uint32, it
should also be named that way.
Rename.
Maybe DHCP plugins should be configurable per address family and be
re-loadable via SIGHUP. But that just adds complexity.
Nowadays we always have the "internal" DHCP plugin, which is known to
support both IPv4 and IPv6. One day, we should get rid of all plugins
and only use one implementation (that works well). The "internal" plugin
is supposed to be(come) that.
That also means, that we are not going to add more (external) DHCP
plugins and we are not going to invest work in the existing plugins
(except the "internal" plugin).
Some DHCP plugins are known to not support IPv6. If the user selects
"dhcpcd" we should just fallback to the "internal" plugin. What's the
point of letting the activation fail? Probably users shouldn't use
"dhcpcd" plugin anyway, but that's a different story. Doing such fallback
could be a problem with forward compatibility if we ever would add IPv6
support to "dhcpcd". But we won't.
Also, we are going to add "n-dhcp4" as replacement for the systemd based
code. For a time, there will be an experimental plugin "nettools" that
eventually will become the new "internal" plugin. Until that happens,
we want for IPv6 automatically fallback to systemd based "internal"
plugin. This patch will make that simple.

When we set the same JSON config twice in a row, the second time has
indeed no effect and we can just return right away (indicating that
no attributes changed).
However, that is not true, if we are in strict validating mode and
the JSON string just happens to be the same. In this case, we still
want to switch from strict validating mode to relaxed mode. Hence,
we should not return early but continue setting the property.
NM_MODEM_OPERATOR_CODE property is construct-only. Add our common
code comment to the property setter.
Construct-only setters are pretty simple. They run before the object is
constructed, hence their scope is clearer. As such, there is no need to
emit property changed notifications (also because that is already taken
care by the GObject property setter). Don't call _nm_modem_set_operator_code(),
just directly set the property.
Usually we aim to have only one place where we set state (_nm_modem_set_operator_code()).
But a construct-only property setter is trivial enough that we can affort having two
places to modify the property. In particular, because the property setter does not "modify"
the property, it merely initializes it before the object is fully
constructed.
When parsing a NMSettingTeam/NMSettingTeamPort from GVariant, the JSON
"config" is always preferred. If that field is present, all other
attributes are ignored (aside from validating that the individual fields
are as expected).
The idea is that the JSON config anyway must contain everything that artificial
properties could. In this mode, also no validation is performed and the setting is
always accepted (regardless whether libnm thinks the setting verifies).
When a libnm client created the setting via the artificial properties,
only send them via D-Bus and exclude the JSON config. This turns on
strict validation server side.
Now we actually get validation of the settings:
$ nmcli connection add type team team.runner-tx-hash l3
Error: Failed to add 'team' connection: team.runner: runner-tx-hash is only allowed for runners loadbalance,lacp
this is obviously a change in behavior as previously all settings
would have been accepted, regardless whether they made sense.
This is fixed in libnm. Resetting the GObject property clears the list
of watchers and tx-hashes.
Since nmcli requires a libnm version >= itself, this workaround
is no longer necessary.
For each artifical team property we need to track whether it was
explicitly set (i.e., present in JSON/GVariant or set by the user
via NMSettingTeam/NMSettingTeamPort API).
--
As a plus, libnm is now no longer concerned with the underling default values
that teamd uses. For example, the effective default value for "notify_peers.count"
depends on the selected runner. But libnm does not need to care, it only cares
wheher the property is set in JSON or not. This also means that the default (e.g. as
interesting to `nmcli -o con show $PROFILE`) is independent from other properties
(like the runner).
Also change the default value for the GObject properties of
NMSettingTeam and NMSettingTeamPort to indicate the "unset" value.
For most properties, the default value is a special value that is
not a valid configuration itself.
For some properties the default value is itself a valid value, namely,
"runner.active", "runner.fast_rate", "port.sticky" and "port.prio".
As far as NMTeamSetting is concerned, it distinguishes between unset
value and set value (including the default value). That means,
when it parses a JSON or GVariant, it will remember whether the property
was present or not.
When using API of NMSettingTeam/NMSettingTeamPort to set a property to the
default value, it marks the property as unset. For example, setting
NM_SETTING_TEAM_RUNNER_ACTIVE to TRUE (the default), means that the
value will not be serialized to JSON/GVariant. For the above 4
properties (where the default value is itself a valid value) this is a
limitation of libnm API, as it does not allow to explicitly set
'"runner": { "active": true }'. See SET_FIELD_MODE_SET_UNLESS_DEFAULT,
Note that changing the default value for properties of NMSetting is problematic,
because it changes behavior for how settings are parsed from keyfile/GVariant.
For team settings that's not the case, because if a JSON "config" is
present, all other properties are ignore. Also, we serialize properties
to JSON/GVariant depending on whether it's marked as present, and not
whether the value is set to the default (_nm_team_settings_property_to_dbus()).
--
While at it, sticter validate the settings. Note that if a setting is
initialized from JSON, the strict validation is not not performed. That
means, such a setting will always validate, regardless whether the values
in JSON are invalid according to libnm. Only when using the extended
properties, strict validation is turned on.
Note that libnm serializes the properties to GVariant both as JSON "config"
and extended properties. Since when parsing a setting from GVariant will
prefer the "config" (if present), in most cases also validation is
performed.
Likewise, settings plugins (keyfile, ifcfg-rh) only persist the JSON
config to disk. When loading a setting from file, strict validation is
also not performed.
The stricter validation only happens if as last operation one of the
artificial properties was set, or if the setting was created from a
GVariant that has no "config" field.
--
This is a (another) change in behavior.
The order of the fields in the JSON object does not really matter.
Note that with the recent rework the order changed. Before it was
arbitrarily, now it still is arbitrary.
Reorder again, to follow the same order as `man teamd.conf`.
This matters for properties that don't have 0/NULL/FALSE as
default value and when setting an empty property with
$ nmcli connection modify "$PROFILE" setting.property ''
Fixes: 3c82db710f ('cli: reset default value of properties via set_fcn()')
The early boot tooling gets the root-path from our state file due to a
lack of a better way to do that. However, when booting with NFS root,
the root path alone is not sufficient; the server address is communicated
via the next-server option. Save that one in the state file as well.

This warning totally defeats the purpose of why we use the pragma in the

I saw this timeout reached in our gitlab-ci. I think it was due to the machine
being busy and taking more than 2 seconds. Assuming the timeout was just too short,
increase it to 4 seconds.
Clang (3.4.2-9.el7) on CentOS 7.6 fails related to nm_hash_update_vals().

This works around the issue.
clang (3.4.2-9.el7) on CentOS 7.6 fails related to nm_hash_update_vals().
I am not even quoting the error message, it's totally non-understandable.
nm_hash_update_vals() uses typeof(), and in some obscure cases, clang dislikes
when the argument itself is some complex macro. I didn't fully understand why,
but this works around it.
I would prefer to fix nm_hash_update_vals() to not have this limitation.
But I don't know how.
There is probably no downside to have this an inline function instead of
a macro.

This code is now unused.
Also, it does not seem state of the art to me
anymore.
Drop it, it could always be resurrected if need by, but maybe
GFileMonitor could be used instead.
It's deprecated and off by default for a long time.
It is bad to automatically reload connection profiles. For example, ifcfg
files may consist of multiple files, there is no guarantee that we
pick up the connection when it's fully written.
Just don't do this anymore.
Users should use D-Bus API or `nmcli connection reload` or `nmcli
connection load $FILENAME` to reload profiles from disk.
