It is redundant. Drop it.
Also, we don't need to cancel and reschedule the idle source in
nm_manager_start(). First of all, it really shouldn't be pending.
Second, contrary to a timer, when an idle source is already pending,
then the pending one will run at the right time.
The _GET_PRIVATE() macros are all implemented based on
_NM_GET_PRIVATE(). That macro tries to be more type safe and uses
_Generic() to do the right thing. Explicitly casting is not only
unnecessary, it defeats these (static) type checks.
Don't do that.
Several macros are used to define function. They had a "_STATIC" variant,
to define the function as static.
I think those macros should not try to abstract entirely what they do.
They should not accept the function scope as argument (or have two
variants per scope). This also because it might make sense to add
additional __attribute__(()) to the function. That only works, if
the macro does not pretend to *not* define a plain function.
Instead, embrace what the function does and let the users place the
function scope as they see fit.
This also follows what is already done with
static NM_CACHED_QUARK_FCN ("autoconnect-root", autoconnect_root_quark)
In all the cases, we don't want to perform locale dependent comparison.
$ sed -i 's/\<strcasecmp\>/g_ascii_\0/g' $(git grep -w -l strcasecmp -- ':(exclude)shared/systemd/' )
We frequently have code that converts a string to number/enum.
Use a preferred implementation via the NM_UTILS_STRING_TABLE_LOOKUP_DEFINE()
macro.
Also, this does binary search, so in most cases it's (slightly) faster.
Defines in our header files should all have an NM specific prefix.
Rename.
Also rename the related defines in the source file. Usually declarations
in a source file should not have an NM prefix. But here they have for
consistency.
We keep adding capabilities. Tracking them individually via boolean (or
ternary) properties is cumbersome.
Instead, use an enum NMSupplCapType and a corresponding bitmask
NMSupplCapMask. The latter can track whether a capability is detected,
detected to be absent or not detected (unknown).
We should handle features/capabilities more generically.
Add an enum type for that. It will be used next.
Also, wpa_supplicant calls this "Capabilities", not features.
Use that name.
Most callers would pass FALSE to nm_utils_error_is_cancelled(). That's
not very useful. Split the two functions and have nm_utils_error_is_cancelled()
and nm_utils_error_is_cancelled_is_disposing().

I think this solution is not right, because "char buf" is not guaranteed
to have the correct alignment. Revert, and solve it differently.
This reverts commit 6345a66153.
When we deactivate a virtual device, we usually schedule the deletion
of the link in an idle handler. That action will be executed at a
later time when the device is already in the disconnected state.
Similarly, for ovs interfaces we send the deletion command to the
ovsdb and then proceed to the disconnected state.
However, in the first case there is the guarantee that the link will
be deleted at some point, while for ovs interfaces it may happen that
ovs decides to reuse the same link if there is an addition
queued. Since reusing the same link confuses NM, let's implement
deactivate_async() for ovs-interfaces and wait that the link actually
goes away before proceeding.

As it is possible to configure an arbitrarily large DHCP timeout, it
should be possible to also set a large timeout for IPv6
autoconfiguration. Currently the timeout can only be changed via
sysctl. Leave the lower bound because the default kernel sysctl value
is 3 * 4 = 12 seconds and so without the lower limit the default
timeout would change from 30 to 12 seconds for every user, which seems
a big change and could possibly break users' setup.

If the current lease expires, we start the grace period in which the
clients starts again from the INIT DHCP state (i.e. sending DISCOVER
messages). If it is able to obtain a new lease, it must be accepted or
otherwise the client will not renew it.
Currently the DHCP client reports the BOUND state not only when the
lease is obtained initially but also when it is renewed. Having a
different state for the renewal will be used by NMDevice in the next
patch to determine whether the lease needs to be accept()ed or not.
Currently the duration of the DHCP grace period (in which we try to
acquire a new lease after expiration) is hardcoded to 480
seconds. That value seems arbitrary and too long for the default
configuration. Since we already have a property that allows the user
to configure how long NM should try to get the lease initially, it
makes sense to use it also for retries after lease expirations.
In particular, setting the ipvx.dhcp-timeout to a high value extends
also the grace period to a very long time, potentially forever.
