Set @ppp_watch_id to zero upon pppd termination, otherwise the call to
g_source_remove(priv->ppp_watch_id) in dispose() could trigger a failed
assertion.
Up to now, the "include" directory contained (only) header files that were
used project-wide by libs, core, clients, et al.
Since the directory now also contains a non-header file, the "include"
name is misleading. Instead of adding yet another directory that is
project-wide, with non-header-only content, rename the "include"
directory to "shared".
Instead of reimplementing constructed() just to call
nm_exported_object_export(), use the 'export_on_construction' flag
which does this automatically. This also fixes the following error:
nm_exported_object_export: assertion failed: (priv->_constructed)

The peer-address (IFA_ADDRESS) can also be all-zero (0.0.0.0).
That is distinct from an usual address without explicit peer-address,
which implicitly has the same peer and local address.
Previously, we treated an all-zero peer_address as having peer and
local address equal. This is especially grave, because the peer is part
of the primary key for an IPv4 address. So we not only get a property of
the address wrong, but we wrongly consider two different addresses as
one and the same.
To properly handle these addresses, we always must explicitly set the peer.
For libnm library, "nm-dbus-interface.h" contains defines like the D-Bus
paths of NetworkManager. It is desirable to have this header usable without
having a dependency on "glib.h", for example for a QT application. For that,
commit c0852964a8 removed that dependancy.
For libnm-glib library, the analog to "nm-dbus-interface.h" is
"NetworkManager.h", and the same applies there. Commit
159e827a72 removed that include.
However, that broke build on PackageKit [1] which expected to get the
version macros by including "NetworkManager.h". So at least for libnm-glib,
we need to preserve old behavior so that a user including
"NetworkManager.h" gets the version macros, but not "glib.h".
Extract the version macros to a new header file "nm-version-macros.h".
This header doesn't include "glib.h" and can be included from
"NetworkManager.h". This gives as previous behavior and a glib-free
include.
For libnm we still don't include "nm-version-macros.h" to "nm-dbus-interface.h".
Very few users will actually need the version macros, but not using
libnm.
Users that use libnm, should just include (libnm's) "NetworkManager.h" to
get all headers.
As a special case, a user who doesn't want to use glib/libnm, but still
needs both "nm-dbus-interface.h" and "nm-version-macros.h", can include
them both separately.

Clone the connection upon activation. This makes it safe for the user
to modify the original connection while it is activated.
This involves several changes:
- NMActiveConnection gets @settings_connection and @applied_connection.
To support add-and-activate, we constructing a NMActiveConnection with
no connection set. Previously, we would set the "connection" field to
a temporary NMConnection. Now NMManager piggybacks this temporary
connection as object-data (TAG_ACTIVE_CONNETION_ADD_AND_ACTIVATE).
- get rid of the functions nm_active_connection_get_connection_type()
and nm_active_connection_get_connection_uuid(). From their names
it is unclear whether this returns the settings or applied connection.
The (few) callers should figure that out themselves.
- rename nm_active_connection_get_id() to
nm_active_connection_get_settings_connection_id(). This function
is only used internally for logging.
- dispatcher calls now get two connections as well. The
applied-connection is used for the connection data, while
the settings-connection is used for the connection path.
- needs special handling for properties that apply immediately
when changed (nm_device_reapply_settings_immediately()).

Refactor agent-manager to always invoke the complete function for
nm_agent_manager_get_secrets().
In general, the complete function is always invoked asnychronously
when starting the operation. On the other hand, when cancelling the
operation or disposing the manager with pending operations, we now
(always) synchronously invoke the callback.
This makes it simpler for the user to reliably cancel the request
and perform potential cleanup.
This behavior bubbles up through NMSettingsConnection and NMActRequest,
and other callers that make directly or indicrectly make use of
nm_agent_manager_get_secrets().
Instead of having the call_id of type guint32, make it an (opaque)
pointer type.
This has the advantage of strong typing and avoids the possiblity
of reusing an invalid integer (or overflow of the call-id counter).
OTOH, it has the disadvantage, that after a call_id is disposed,
it might be reused for future invocations (because malloc might
reuse the memory).
In fact, it is always an error to use a call_id that is already
completed. This commit also adds assertions to the cancel() calls
that the provided call_id is a pending call. Hence, such a bug
will be uncovered by assertions (that only might not tigger in
certain unlikely cases where a call-id got reused).
Note that for NMAgentManager, save_secrets() and delete_secrets()
both returned a call_id. But they didn't also provide a callback when
the operation completes. So the user trying to cancel such a call,
cannot know whether the operation is still in process and he cannot
avoid triggering an assertion.
Fix that by not returning a call-id for these operations. No caller
cared about it anyway.
For NMSettingsConnection, also track the internally scheduled requests
for so that we can cancel them on dispose.
This internal header file should be included by our internal source
code files and header files. It includes in one place other headers
that constitute to a minimal set of required headers. Most notably
this is <glib.h> and our "nm-glib.h" header.
Note that public header files and example source code cannot include
this file as "nm-default.h" is internal only.
Our gdbus generated types use the same names as their corresponding
"real" types, but with "NM" changed to "NMDBus".
Unfortunately, that means that introspection/nmdbus-manager.c (the
generated type for src/nm-manager.c) uses the same type name as the
entirely unrelated src/nm-dbus-manager.c.
Fix this by removing the "d" from src/nm-dbus-manager.c. (We could
rename the generated type instead, but then it becomes inconsistent
with all the other generated types, and we're already using it as
"NMDBusManager" in libnm/nm-manager.c.)
Move D-Bus export/unexport handling into NMExportedObject and remove
type-specific export/get_path methods (export paths are now specified
at the class level, and NMExportedObject handles the counters for all
exported types automatically).
Since all exportable objects now use the same get_path() method, we
can also add some helper methods to simplify get_property()
implementations for object-path and object-path-array properties.
Add NMExportedObject, make it the base class of all D-Bus-exported
types, and move the nm-properties-changed-signal logic into it. (Also,
make NMSettings use the same properties-changed code as everything
else, which it was not previously doing, presumably for historical
reasons).
(This is mostly just shuffling code around at this point, but
NMExportedObject will be more important in the gdbus port, since
gdbus-codegen doesn't do a very good job of supporting objects that
export multiple interfaces [as each NMDevice subclass does, for
example], so we will need more glue/helper code in NMExportedObject
then.)
Rather than randomly including one or more of <glib.h>,
<glib-object.h>, and <gio/gio.h> everywhere (and forgetting to include
"nm-glib-compat.h" most of the time), rename nm-glib-compat.h to
nm-glib.h, include <gio/gio.h> from there, and then change all .c
files in NM to include "nm-glib.h" rather than including the glib
headers directly.
(Public headers files still have to include the real glib headers,
since nm-glib.h isn't installed...)
Also, remove glib includes from header files that are already
including a base object header file (which must itself already include
the glib headers).
We don't want error logging for nm_platform_link_add() which
tries to load the bonding module. Later we will run tests as non-root,
where modprobe will fail. Logging an error would break the tests.

In file included from ppp-manager/nm-ppp-manager.c:42:0:

We switched to user-mode PPPoE client to work around a bug in kernel
PPPoE code that caused pppd not to be notified when the connection was
terminated with a PADT before the LCP Termination Request.
The kernel bug has now been fixed upstream with commit 287f3a943fef
"pppoe: Use workqueue to die properly when a PADT is received", queued
for v4.1.
Since the issue affected only very particular scenarios and could
somehow be solved with the right configuration (see bugzilla entry),
we can safely revert the patch and restore the use of kernel mode
PPPoE.
This reverts commit 7955806a02.

Most nm_platform_*() functions operate on the platform
singleton nm_platform_get(). That made sense because the
NMPlatform instance was mainly to hook fake platform for
testing.
While the implicit argument saved some typing, I think explicit is
better. Especially, because NMPlatform could become a more usable
object then just a hook for testing.
With this change, NMPlatform instances can be used individually, not
only as a singleton instance.
Before this change, the constructor of NMLinuxPlatform could not
call any nm_platform_*() functions because the singleton was not
yet initialized. We could only instantiate an incomplete instance,
register it via nm_platform_setup(), and then complete initialization
via singleton->setup().
With this change, we can create and fully initialize NMPlatform instances
before/without setting them up them as singleton.
Also, currently there is no clear distinction between functions
that operate on the NMPlatform instance, and functions that can
be used stand-alone (e.g. nm_platform_ip4_address_to_string()).
The latter can not be mocked for testing. With this change, the
distinction becomes obvious. That is also useful because it becomes
clearer which functions make use of the platform cache and which not.
Inside nm-linux-platform.c, continue the pattern that the
self instance is named @platform. That makes sense because
its type is NMPlatform, and not NMLinuxPlatform what we
would expect from a paramter named @self.
This is a major diff that causes some pain when rebasing. Try
to rebase to the parent commit of this commit as a first step.
Then rebase on top of this commit using merge-strategy "ours".
No functional change, a cosmetic thing for now.
We want it set before any routes are added and ensure routes have a valid
ifindex before we pass it to the platform.
In a future NMRouteManager will need to look up the route for a device in
its cache thus we'll need to make sure routes passed to the it have an
appropriate ifindex set.

Add nm_utils_setpgid() as a g_spawn*() child setup function for
calling setpgid(), and use it where appropriate rather than
reimplementing it every time.
Replace the pthread_sigwait()-based signal handling with
g_unix_signal_add()-based handling, and get rid of all the
now-unnecessary calls to nm_unblock_posix_signals() when spawning
subprocesses.
As a bonus, this also fixes the "^C in gdb kills NM too" bug.
config.h should be included from every .c file, and it should be
included before any other include. Fix that.
(As a side effect of how I did this, this also changes us to
consistently use "config.h" rather than <config.h>. To the extent that
it matters [which is not much], quotes are more correct anyway, since
we're talking about a file in our own build tree, not a system
include.)
Add nm-core-types.h, typedefing all of the GObject types in
libnm-core; this is needed so that nm-setting.h can reference
NMConnection in addition to nm-connection.h referencing NMSetting.
Removing the cross-includes from the various headers causes lots of
fallout elsewhere. (In particular, nm-utils.h used to include
nm-connection.h, which included every setting header, so any file that
included nm-utils.h automatically got most of the rest of libnm-core
without needing to pay attention to specifics.) Fix this up by
including nm-core-internal.h from those files that are now missing
includes.
A number of classes in core had their own error domains that aren't
really necessary.
In the case of NMDcbError, NMDhcpManagerError, NMDnsManagerError,
NMDnsmasqManagerError, NMPppManagerError, and NMSessionMonitorError,
most of the codes they defined weren't even being used, and at any
rate, the errors were always returned into contexts where they would
just have their message extracted and then get thrown away without
anyone ever looking at the domain or code. So all uses of those
domains can just be replaced with NM_MANAGER_ERROR_FAILED without any
loss of information.
NMAuthManagerError only had 1 error code, and it just indicated
"something went wrong", so it can be replaced with
NM_MANAGER_ERROR_FAILED without loss of information.
(nm-auth-manager.c has also been fixed to return
NM_MANAGER_ERROR_FAILED when the CheckAuthorization D-Bus call fails,
rather than returning whatever error domain/code the D-Bus call
returned.)
NMVpnManagerError used 2 of its 4 error codes, and they could actually
end up getting returned across D-Bus in some cases. But there are
NMManagerError codes that are semantically similar enough to make the
NMVpnManagerError ones unnecessary.
Instead of having basically the same code in a bunch of different
place to find helper programs, just have one place do it. Yes, this
does mean that the same sequence of paths is searched for all helpers
(so for example, dnsmasq will no longer be found first in /usr/local)
but I think consistency is the better option here.

Previously, src/nm-ip4-config.h, libnm/nm-ip4-config.h, and
libnm-glib/nm-ip4-config.h all used "NM_IP4_CONFIG_H" as an include
guard, which meant that nm-test-utils.h could not tell which of them
was being included (and so, eg, if you tried to include
nm-ip4-config.h in a libnm test, it would fail to compile because
nm-test-utils.h was referring to symbols in src/nm-ip4-config.h).
Fix this by changing the include guards in the non-API-stable parts of
the tree:
- libnm-glib/nm-ip4-config.h remains NM_IP4_CONFIG_H
- libnm/nm-ip4-config.h now uses __NM_IP4_CONFIG_H__
- src/nm-ip4-config.h now uses __NETWORKMANAGER_IP4_CONFIG_H__
And likewise for all other headers.
The two non-"nm"-prefixed headers, libnm/NetworkManager.h and
src/NetworkManagerUtils.h are now __NETWORKMANAGER_H__ and
__NETWORKMANAGER_UTILS_H__ respectively, which, while not entirely
consistent with the general scheme, do still mostly make sense in
isolation.
Include <linux/if_ether.h> and <linux/if_infiniband.h> from
nm-utils.h, to get ETH_ALEN and INFINIBAND_ALEN, and remove those
includes (as well as <net/ethernet.h> and <netinet/ether.h>, and
various headers that had been included to get the ARPHRD_* constants)
from other files where they're not needed now.
Add NetworkManager.h, which includes all of the other NM header, and
require all external users of libnm to use that rather than the
individual headers.
(An exception is made for nm-dbus-interface.h,
nm-vpn-dbus-interface.h, and nm-version.h, which can be included
separately.)
"NetworkManager.h"'s name (and non-standard capitalization) suggest
that it's some sort of high-level super-important header, but it's
really just low-level D-Bus stuff. Rename it to "nm-dbus-interface.h"
and likewise "NetworkManagerVPN.h" to "nm-vpn-dbus-interface.h"
For some reason, the flags used by o.fd.NM.SecretAgent.GetSecrets were
defined as both NMSecretAgentGetSecretsFlags in
libnm{,-glib}/nm-secret-agent.h, and then separately as
NMSettingsGetSecretsFlags in include/nm-settings-flags.h.
(NMSettingsGetSecretsFlags also had an additional internal-use-only
value, but that was added later after the duplication already
existed.)
Fix this by moving NMSecretAgentGetSecretsFlags from libnm to
nm-dbus-interface.h, adding the internal-use-only value to it as well,
updating the core code to use that, and then removing
nm-settings-flags.h.
GLib/Gtk have mostly settled on the convention that two-letter
acronyms in type names remain all-caps (eg, "IO"), but longer acronyms
become initial-caps-only (eg, "Tcp").
NM was inconsistent, with most long acronyms using initial caps only
(Adsl, Cdma, Dcb, Gsm, Olpc, Vlan), but others using all caps (DHCP,
PPP, PPPOE, VPN). Fix libnm and src/ to use initial-caps only for all
three-or-more-letter-long acronyms (and update nmcli and nmtui for the
libnm changes).
Since the API has not changed at this point, this is mostly just a
matter of updating Makefiles, and changing references to the library
name in comments.
NetworkManager cannot link to libnm due to the duplicated type/symbol
names. So it links to libnm-core.la directly, which means that
NetworkManager gets a separate copy of that code from libnm.so.
Everything else links to libnm.
