Internally, the options are tracked in a hash table and of undefined
sort order. However, nm_setting_bond_get_option() always returns a stable
(sorted) order.
Move "mode" as first, because that is usually the most interesting option.
The effect is:
$ nmcli -o connection show "$BOND_PROFILE"
...
-bond.options: arp_interval=5,arp_ip_target=192.168.7.7,arp_validate=active,mode=balance-rr,use_carrier=0
+bond.options: mode=balance-rr,arp_interval=5,arp_ip_target=192.168.7.7,arp_validate=active,use_carrier=0
This doesn't affect keyfile, which sorts the hash keys themself (and
doesn't treat the "mode" special).
This however does affect ifcfg-rh writer how it writes the BONDING_OPTS
variable. I think this change is fine and preferable.
strcmp() is hard to understand visually. Especially when different patterns
are mixed, like:
if ( !strcmp (name, NM_SETTING_BOND_OPTION_MIIMON)
&& strcmp (value, "0") != 0) {
When AddConnection() or Update() terminate, the (unrealized) virtual
device should be already be available, otherwise an activation attempt
of that connection can fail.

This reverts commit c163207b07.
The interface name might come from the command line or from a filename
(like during nm_vpn_wireguard_import()). It's not clear that this
is valid UTF-8. Asserting against that requires the caller to ensure
that the encoding is valid. That is cumbersome, especially since we anyway
check. Just report a regular error.
quoting 'man ovs-vswitchd.conf.db':
"The name must be alphanumeric and must not contain forward or backward
slashes."
OVS actually accepts a wider range of chars (all printable UTF-8 chars),
NetworkManager restricts this to ASCII char as it's a safer option for
now since OVS is not well documented on this matter.

Fixes: e7d72a14f6 ('libnm-core: use different ifname validation function for OVS bridges, ports and interfaces')
When the ovs interface gets deactivated, it is released from the
master port and we call nm_device_update_from_platform_link (dev,
NULL) to ignore any later event for the interface. This is important
especially because it sets a zero ifindex on the interface and so,
later when the link disappears, we don't unmanage the device but
directly remove it.
However, since ovs commands are queued, the link could appear during
the deactivation and we need to ignore such events. Add a new device
method can_update_from_platform_link() for such purpose.
Tracking the deletion of link by ifindex is difficult because the
ifindex of the device is updated through delayed (idle) calls in
NMDevice and so there is the possibility that at a certain time the
device ifindex is not in sync with platform state. It seems simpler to
watch instead the interface name. The ugly thing is that the interface
name can be changed externally, but if users do that on an activating
device they are looking for trouble.
Also change the deactivate code to deal with the scenario where we
already created the interface in the ovsdb but the link didn't show up
yet. To ensure a proper cleanup we must wait that the link appears and
then goes away; however the link may never appear if vswitchd sees
only the last state in ovsdb, and so we must use a ugly timeout to
avoid waiting forever.

The only affected caller is nm_modem_manager_get_modems(), which
is used by NMDeviceBt for DUN connections. This is rather bad.

OVS bridges and ports do not have the length limitation of 15 bytes, the
only requirements are that all chars must be alphanumeric and not be
forward or backward slashes.
For OVS interfaces only 'patch' types do not have the length limit, all
the other types do (according to whether they have a corresponding
kernel link or not).
Add related unit test.

'self' is guaranteed of being not-NULL since we have the
assertion 'g_return_val_if_fail (NM_IS_SETTING_OVS_INTERFACE (self),FALSE);'
at the beginning of the function.
nm_utils_is_valid_iface_name() is a public API of libnm-core, let's use
our internal API.
$ sed -i 's/\<nm_utils_is_valid_iface_name\>/nm_utils_ifname_valid_kernel/g' $(git grep -l nm_utils_is_valid_iface_name)
nmcli should not perform checks on the interface name length,
this kind of operations should only be performed by the NetworkManager
daemon and not be duplicated inside cli applications.
nm_setting_ip6_config_get_ra_timeout() was backported to nm-1-22 branch, and
will be released as 1.22.8. As such, on the stable branch the symbol will be
placed in a separate symbol version ("libnm_1_22_8").
To support the upgrade path from 1.22.8+ to 1.23+, we want this symbol
also present on master.
At that point, we don't need to duplicate the symbol. Just add the same linker
symbol version also to master.
At this point, just move the fields in their respective address-family
specific structure. We don't use it generically yet, but instead always
explicitly select IPv4 or IPv6. But this would allow to access those
fields by address-family in the future.
Often, the code paths for IPv4 and IPv6 are very similar. We should try
to unify those code paths. The main advantage of doing that, is that
we don't unintentionally end up doing different things. And of course,
it removes duplicate code.
In a first step, unify handling of the grace timeout for DHCPv4 and
DHCPv6.
We will add a property NM_NDISC_RA_TIMEOUT for which this name is better
suited. The problem is really that our convention for object properties
and signals defines have no prefix to indicate whether it's a property
or a signal.
Rename.
It is undefined behavior and can lead to crashes or memory corruption.
In practice, this only had an issue on Big Endian systems.
Fixes: fdbf4ae5e6 ('ifcfg-rh: add IPV4_DHCP_TIMEOUT key for ipv4.dhcp-timeout property')
If a function is only called once, it may not help to simplify the code
but make it more complicated. It would only simplify the code, if it
had a clear, distinct purpose. That isn't the case here. Also, the
IPv4 writer doesn't have such a function either. Drop and inline it.
This is C, we have almost no IDE support. And ctags/cscope is much more
helpful if we use unique names.
Don't use the get_dhcp_timeout() name, because that is already used in
"src/devices/nm-device.c" already. Rename.

already LGPL licensed).
