1c187b7f54 manager: forbid autoactivation of parent when it is blocked by user request
If a device is being autoactivated and requires a parent that is
blocked due to user request, the autoactivation attempt should fail
because NM shouldn't overrule the user decision.

bd7c768b79 initrd: fix setting VLan ID in reader_parse_vlan()
g_ascii_strtoull() returns a guint64, which is very wrong to directly pass
to the variadic argument list of g_object_set(). We expect a guint there
and need to cast.

While at it, use _nm_utils_ascii_str_to_int64() to parse and validate the input.

0f80291a93 device: fix setting MTU from connection when limited by parent
We try to set only one time the MTU from the connection to not
interfere with manual user changes.

If at some point the parent interface changes temporarily MTU to a
lower value (for example, because the connection was reactivated), the
kernel will also lower the MTU on child interface and we will not
update it ever again.

Add a workaround to this. If we detect that the MTU we want to set
from connection is higher that the allowed one, go into a state where
we follow the parent MTU until it is possible to set again the desired
MTU. This is a bit ugly, but I can't think of any nicer way to do it.

24fae58dd8 macsec: update MTU according to parent's one
A MACsec connection doesn't have an ordering dependency with its
parent connection and so it's possible that the parent gets activated
later and sets a greater MTU than the original one.

It is reasonable and useful to keep the MACsec MTU configured by
default as the maximum allowed by the parent interface, that is the
parent MTU minus the encapsulation overhead (32). The user can of
course override this by setting an explicit value in the
connection. We already do something similar for VLANs.

bbd5802f00 device: introduce generic function to inherit MTU from parent
Introduce a generic function to set a MTU based on parent's one. Also
define a device-specific @mtu_parent_delta value that specifies the
difference from parent MTU that should be set by default. For VLAN it
is zero but other interface types (for example MACsec) require a
positive value due to encapsulation overhead.

57e2f76f57 supplicant: fix memory corruption with wrong argument to NM_SUPPLICANT_INTERFACE_GROUP_FORMATION_FAILURE signal
The signal is unused (and should be removed).

Still, the parameter passed to g_signal_emit() is a C string, not a
GVariant. I think as there are no subscribers, glib wouldn't actually
do anything with the arguments. Though, I am not sure whether glib still
tries to initialize a GValue with a GVariant type, leading to a crash.

dc03a26494 manager: create a virtual device only if the connection can autoconnect
The autoconnection for virtual devices currently works in two
phases. First we detect that there is suitable profile that can
autoconnect and we realize the device. Then, when the device becomes
'disconnected', autoconnect kicks in and starts the activation.

However, if autoconnect is blocked for a device, currently we do step
1 without step 2, leaving a stale interface around. Fix this by also
checking that autoconnect is not blocked during step 1.

50bae00473 device: don't transition assumed devices to FAILED before ACTIVATED
If the activation of an assumed device fails, we first set the device
state to FAILED and then to ACTIVATED. In the FAILED state, the active
connection transitions to DEACTIVATED and clears its device pointer;
hence we end up with an inconsistent state which causes assertion
failures in other parts of the code (for example, get_best_ip_config()
assumes that the device of the best active connection is not NULL).

Don't first transition to FAILED and then to ACTIVATED, just set the
latter.

1ff0ba0fab platform: make nm_platform_kernel_support_get() macro an inline function
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.

07ccf36ed0 platform/tests: rename platform's "test-general.c"
Older versions of meson don't like building multiple artifacts
with the same name (even if they are in different directories). We
have multiple tests called "test-general.c", and it would be natural
to compile a test binary of the same name.

  Meson encountered an error in file src/tests/meson.build, line 14, column 2:
  Tried to create target "test-general", but a target of that name already exists.

It's generally a bad idea to have in our source tree multiple files with the
same name. Rename the test.

0f1900b4f7 build/meson: rename platform tests to use same name as autotools
First of all, all file names in our source-tree should be unique. We should
not have stuff like "libnm-core/tests/test-general.c" and "src/tests/test-general.c".
The problem here are the C source files, and consequently also the test
binaries have duplicate names. We should avoid that in general. However,
our binaries should have a matching name with the C source. If
"test-general.c" is not good enough, that needs renaming. Not building
"platform-test-general" out of it.

On the other hand, all our tests should have a filename "*/tests/test-*", like
they do for autotools.

Rename the meson platform tests.

It's also important because "tools/run-nm-test.sh" relies on the test
name to workaround valgrind warnings.

bug in _nm_ip_config_add_obj(). When an address is added to the tail
of the index and another address with the same id already exists, the
existing object is left at the same place, breaking the order of
addresses.

134ccb4a17 core/lldp: minor cleanup in _lldp_attr_*()
- use nm_g_variant_unref_floating()

- rename _lldp_attr_take_str_ptr() to _lldp_attr_set_str_take().
  The new name has the same "_lldp_attr_set_" prefix as other setters.
  Also, with the previous name it is unclear why it takes a "str-ptr".

- setting the same attribute multiple times, ignores all but the first
  value. Avoid cloning the string in that case, and explicitly choose
  the set or take function.

a1f39b69e0 ovs: don't release slaves on quit
An OVS bridge and its slaves can continue to work even after NM has
quit. Keep the interface enslaved when the @configure argument of
device->release_slave() is FALSE, which happens on quit and in other
circumstances when we don't really want to release the slave from its
master.

f6a90b899a device: fix releasing slaves
Not all masters type have a platform link and so it's wrong to check
for it to decide whether the slave should be really released. Move the
check to master devices that need it (bond, bridge and team).

OVS ports don't need the check because they don't call to platform to
remove a slave.

511ef27d5e device: check platform link compatibility when setting nm-owned flag
We set nm-owned to indicate whether a software device was created by
NM or it was pre-existing. When checking the existence, we must verify
also whether the link type is compatible with the device, otherwise it
is possible to match unrelated interfaces. For example, when checking
for the existence of an ovs-bridge (which is not compatible with any
platform link) we could match a unrelated platform link with the same
name.

a3e51a74aa policy-routing: take ownership of externally configured rules
IP addresses, routes, TC and QDiscs are all tied to a certain interface.
So when NetworkManager manages an interface, it can be confident that
all related entires should be managed, deleted and modified by NetworkManager.

Routing policy rules are global. For that we have NMPRulesManager which
keeps track of whether NetworkManager owns a rule. This allows multiple
connection profiles to specify the same rule, and NMPRulesManager can
consolidate this information to know whether to add or remove the rule.

NMPRulesManager would also support to explicitly block a rule by
tracking it with negative priority. However that is still unused at
the moment. All that devices do is to add rules (track with positive
priority) and remove them (untrack) once the profile gets deactivated.

As rules are not exclusively owned by NetworkManager, NetworkManager
tries not to interfere with rules that it knows nothing about. That
means in particular, when NetworkManager starts it will "weakly track"
all rules that are present. "weakly track" is mostly interesting for two
cases:

  - when NMPRulesManager had the same rule explicitly tracked (added) by a
    device, then deactivating the device will leave the rule in place.

  - when NMPRulesManager had the same rule explicitly blocked (tracked
    with negative priority), then it would restore the rule when that
    block gets removed (as said, currently nobody actually does this).

Note that when restarting NetworkManager, then the device may stay and
the rules kept. However after restart, NetworkManager no longer knows
that it previously added this route, so it would weakly track it and
never remove them again.

That is a problem. Avoid that, by whenever explicitly tracking a rule we
also make sure to no longer weakly track it. Most likely this rule was
indeed previously managed by NetworkManager. If this was really a rule
added by externally, then the user really should choose distinct
rule priorities to avoid such conflicts altogether.

5a565659fa initrd: skip ethernet hwtype in BOOTIF
Dracut documents the BOOTIF argument to be a MAC address and so we
accept one in any of the conventions we recognize. However, the PXE boot
loaders like to prepend a "01-" to denote an ethernet hardware type.
Accept that too.

0d9a62c25e initrd: don't create a default connection if there's already one
Certain arguments (such as "nameserver") don't specify a connection they
apply to and using them would generate a default ethernet connection.
This is probably not the right thing to do.
