- "gsystem-local-alloc.h" and <gio/gio.h> are already included via
"nm-default.h". No need to include them separately.
- include "nm-macros-internal.h" via "nm-default.h" and drop all
explict includes.
- in the modified files, ensure that we always include "config.h"
and "nm-default.h" first. As second, include the header file
for the current source file (if applicable). Then follow external
includes and finally internal nm includes.
- include nm headers inside source code files with quotes
- internal header files don't need to include default headers.
They can savely assume that "nm-default.h" is already included
and with it glib, nm-glib.h, nm-macros-internal.h, etc.
The existing checks assumed that all AP/AdHoc connections would use the
shared IP method. But what we really want to check for here is whether the
connection is AP/AdHoc. Leave the existing 'shared' check for backwards
compatibility.
Also move the check above the timestamp check, since the user shouldn't need
to manually set a timestamp just to get an AP-mode connection to autoconnect.
Since commit 9ff161b2a1 ("device: move have_ip6_address() to
nm_ip6_config_get_address_first_nontentative()") the IP configuration
argument of nm_ip6_config_get_address_first_nontentative() must be
non-NULL. Add checks where needed.
Fixes: 9ff161b2a1
We should not check ip6_config for the link local address because
ip6_config contains the merged settings we want to configure,
not the addresses that are actually configured on the device.
Check ext_ip6_config_captured for that.
Also, reuse nm_ip6_config_get_address_first_nontentative() which
only takes an address after it survived DAD.
It will only be in ext_ip6_config if it was added by the kernel,
which isn't usually the case since NM handles IPv6LL address
generation on new enough kernels.
If the LL address isn't found, IPv6 configuration will never
complete because DHCPv6 was started already but lack of an LL
address bails out early without handling the error.

Calling va_start() (with va_end()) in between seems to work and
is done by systemd and other code occasionally.
However, it's not clear that this really works on every architecture.
So just replace thise one instance with a different implementation
by passing the arguments as an array.
First, cb751012a2 mistakenly converted the
act_stage_context_step() in connect_ready() to connect_context_clear()
instead of connect_context_step(). This would cause the IP Type retry
logic to fail and no further types to be tried. It also throws
away the ctx->first_error and causes all errors that MM returns on the
connect attempt to be dropped on the floor.
Second, not all errors should cause an advance to the next IP Type,
since some errors aren't related to it. Specifically, MM_CORE_ERROR_RETRY
when using Simple.Connect() means that a timeout was reached
in the internal connect logic, not a modem or network error. In
that case, try the connect again with the same IP Type before advancing
to the next type.

When we decide to add a new link, we alredy checked that no such link exists
(ignoring race conditions).
It is wrong to accept a EXITS failure when adding the link. There is no guarantee
that the existing link has all the same properties as the one we intend to add.
More importantly, this link was added externally outside of NetworkManager and it
should not be taken over.
Just treat EXISTS as a failure as any other.
NM_DEVICE_CHECK_CON_AVAILABLE_FOR_USER_REQUEST is a multi-flag value combining all
the hooks that compose a user-request. Add a special value that has no esplicit
meaning except that it ~is~ a user-request.
For update, don't delete first and add it again. Just do it
in one step.
For recheck, don't delete all connections first to add them
all anew. Instead, check what changes and only emit the changed
signal if there are any actual changes.
The rules were added to the list using g_slist_append() and then
applied one at time using "iptables --insert" which puts them at the
beginning of the chain, reversing the initial order.
Instead, list them in the desired order and use g_slist_prepend() to
achieve the same result. This has no functional changes.
nm_supplicant_manager_iface_get() would cache and reuse the supplicant
interface. But no ref-counting was in place so that the first user returning
the interface via nm_supplicant_manager_iface_release() would destroy the
instance for others.
This is broken for a very long time. Which shows that we hardly ever
have a cache-hit and usually create a new instance. So, instead of
letting nm_supplicant_manager_create_interface() check for existing
supplicant interface, always create a new instance. This also makes
sense, because we would expect that per ifname only one instance is
requested at a time. Also add an assertion that we don't return
multiple supplicant interface instances for the same ifname.
Drop nm_supplicant_manager_iface_release() in favor of requiring users
to unref the returned instance.
Also, use a GSList instead of a GHashTable for the cache.
Also, previously callers would pass @is_wireless to nm_supplicant_manager_iface_get(),
but the cache lookup did not consider that value. That doesn't matter
now as we always create a new instance.

Add a new object which implements the logic for announcing IP

The function can now be called on unrealized devices before the
initial unmanaged flags are set and for those devices
nm_device_get_managed() will return TRUE. Since we only accept
states > UNMANAGED, return early when the condition is not met.
Fixes the following failed assertion:
carrier_changed: assertion 'priv->state >= NM_DEVICE_STATE_UNAVAILABLE' failed
https://bugzilla.gnome.org/show_bug.cgi?id=760844
The availability checks are called from places that don't assume the device
will be removed mid-air. Call the removal routine only when we're the very
last thing that's being done.
During nm_device_unrealize(), the connection might still
have some connections that only get removed later. We must
garbage collect unrealized devices when they loose their
available-connections, not during unrealize.
Fixes: 436ec5b8e3
Apply MTU and hop limit when managed or other flag is set as well. This wasn't
the case for the first RA and the previous commit made it slightly worse by
always ignoring it.

With DHCPv6 it might be quite some time (we may even time out) until we get all
the information to finish activation, but we already have the addresses and
routes.
With the final removal the reason of NOW_UNMANAGED causes the cleanup on the
device to be run, which downs the device:
