We don't always want to immediately write new connections to disk, to
facilitate "runtime" or "temporary" connections where an interface's
runtime config isn't backed by on-disk config. Also, just because
an interface's configuration is changed doesn't necessarily mean
that new configuration should be written to disk either.
Add D-Bus methods for adding new connections and for updating existing
connections that don't immediately save the connection to disk.
Also add infrastructure to indicate to plugins that the new connection
shouldn't be immediately saved if the connection was added with the
new method.
Use the new NMConnection 'changed' signal to mark connections
as dirty/unsaved, and reset that when they get flushed to disk.
Previously, the 'Updated' signal was emitted only when the
connection was changed and flushed to disk, but now we have
more granular needs, and the signal is emitted whenever the
connection actually *is* changed, regardless of whether its
flushed to disk or not.
Although having different parts of NM in different subdirectories
keeps the source tree neat, it has made the build messy, particularly
because of cross-dependencies between the subdirs.
Reorganize to build all of the pieces of the NetworkManager binary
from src/Makefile, and only use recursive make for test programs,
helper binaries, and plugins.
As part of this, get rid of all the per-directory convenience
libraries, and switch to building a single top-level
libNetworkManager.la, containing everything except main.c, which all
of the test programs can then link against.
STP defaults to yes in NetworkManager (and the initscripts), so a missing
STP value in an ifcfg file means yes/on. Calling svSetValue(STP, NULL)
clears that line from the ifcfg, and thus STP gets interpreted as yes.
Explicitly set stp to "no" so that the value actually gets saved.
For settings corresponding to devices that have a :carrier property
(ie bond, bridge, infiniband, vlan, and wired), add a :carrier-detect
property specifying how that affects the connection:
yes: The connection can only be activated when the device
has carrier, and will be deactivated if the device loses
carrier (for more than 4 seconds).
no: The connection ignores carrier on the device; it can be
activated when there is no carrier, and stays activated
when carrier is lost.
on-activate: The connection can only be activated when the
device has carrier, but it will not be deactivated if the
device loses carrier.

GObject creation cannot normally fail, except for types that implement
GInitable and take a GError in their _new() method. Some NM types
override constructor() and return NULL in some cases, but these
generally only happen in the case of programmer error (eg, failing to
set a mandatory property), and so crashing is reasonable (and most
likely inevitable anyway).
So, remove all NULL checks after calls to g_object_new() and its
myriad wrappers.

g_malloc(), etc, never return NULL, by API contract. Likewise, by
extension, no other glib function ever returns NULL due to lack of
memory. So remove lots of unnecessary checks (the vast majority of
which would have immediately crashed had they ever run anyway, since
g_set_error(), g_warning(), and nm_log_*() all need to allocate
memory).

Allows to attach any connection to a bridge using the BRIDGE= key.
IP configuration is optional for bridge components but not
prohibited. Test case included.
This patch makes DHCPv6 support more or less equivalent to that
one of IPv4 DHCP.
(dcbw: fix some formatting, rearrange code so it's less convoluted,
fix up writing hostname to ifcfg files)
Use --enable-doc and --enable-tests instead of --with-docs and
--with-tests. This is consistent with other features and with
--enable-gtk-doc option. Support current variants as fallback.
Don't build tests unless --enable-tests is specified.
When determining the system hostname, /etc/hostname should override
/etc/sysconfig/network, so monitor both files.
When setting the hostname, set it in /etc/hostname, and delete the
/etc/sysconfig/network HOSTNAME entry if present.

We had separate checks for glib-2.0, gobject-2.0, gmodule-2.0, and
gio-unix-2.0. It doesn't make sense to link a binary against all 4
because gio-unix-2.0 depends on glib-2.0 and gobject-2.0. Doing this
actually breaks things in unusual circumstances.
Generally, few bits of NM actually just use glib, and not gio. We
might as well coalesce those requirements together, even if it means
in some cases we "overlink". Additionally, I chose for now to fold
gmodule-2.0 in as well, even though many fewer programs need it. The
cost of overlinking is quite small.
The benefit of this is less repeated junk in Makefile.am, as well as
more centralized control over GLib. A followup patch will allow us to
set -DGLIB_VERSION_MIN_REQUIRED in just one place, rather than having
to replicate it 4 times.
The NM configure is still suboptimal - for example, libpolkit-1
depends on gio-2.0, so really we should determine the compiler flags
all in one pass. But it doesn't matter too much for now.
This functionality is (mostly) obsoleted by the newer
GLIB_VERSION_MIN_REQUIRED and GLIB_VERSION_MAX_ALLOWED defines. With
this, your build doesn't all of a sudden blow up if we deprecate
something in GLib - you have to explicitly opt-in to the newer
version.
G_DISABLE_DEPRECATED does still apply for macros and things that can't
take __attribute__((deprecated)), but it's not really worth the pain
and cargo culting around just for that.
VLAN connections can have "hardware" settings in addition to the
VLAN-specific ones. ifcfg-rh was reading in wired settings for VLANs,
but was not writing them back out.
The ctype macros (eg, isalnum(), tolower()) are locale-dependent. Use
glib's ASCII-only versions instead.
Also, replace isascii() with g_ascii_isprint(), since isascii()
accepts control characters, which isn't what the code wanted in any of
the places where it was using it.
NM was requiring that bond slaves have either no IP config or an
explicit "none"/"disabled" config. But the system scripts just ignore
any IP config that is present on a slave, so change NM to do that too
(but warn about it).

When the last character of the PSK was a backslash and the whole PSK was
enclosed in single quotes, the unquoting/unescaping code mistakenly took
trailing \' as an escaped quote and thus changed \ to '.
See also 79757f10f3 (that introduced the code).
Commit 217c5bf6ac fixed processing of unix
signals: signals are blocked in all threads and a dedicated thread handles the
signals using sigwait().
However, the commit forgot that child processes inherit signal mask as well.
That is why we have to unblock signals for child processes we spawn from NM, so
that they can receive signals.
A vlan DEVICE name must be either $(OTHERDEVICE).$(VLAN_ID) or
vlan$(VLAN_ID). Enforce that. In particular, don't:
(a) crash if the name has no "." and doesn't start with "vlan",
(b) loop forever if the $(VLAN_ID) part is non-numeric, or
(c) silently ignore non-numberic characters after the $(VLAN_ID).
It is currently not possible to create a connection where the
connection-type-specific NMSetting has all default values. This hasn't
been a problem in the past because each type had at least one property
that either had no default value or had a default value that didn't
pass verify(). But NMSettingInfiniband didn't have that property, so
it's impossible to create an InfiniBand connection unless you change
the value of at least InfiniBand-specific setting.
Work around this for now by making the default value of
NMSettingInfiniband:transport-mode be NULL, so it needs to be
overridden.

This allows out-of-the-box connectivity on IPv6-only networks.
Once caveat is that connections where the user currently
expects no IPv4 connectivity to terminate the connection and
retry will no longer do so until IPv6 also times out, and if
that network where IPv4 is expected to fail also has an IPv6
router sending advertisements, the connection will succeed
instead of failing. That can be resolved by setting the
right bit in the connection's config file; and it's expected
that the number of users who expect IPv4 failure on a
network with usable IPv6 connectivity is quite small
compared to the benefit of OOB IPv6 connectivity.
Single quotes ensure we don't break initscripts (bash processing) when the
string contains special characters. Special handling is necessary for single
quotes characters. They have to be escaped and the whole string has to be
prepended with '$' character so that bash is happy.
This change also filters out CR and LF characters as they break WPA_PSK
variable and could pose security issues.
"InfiniBand" has a capital "B". Fix that everywhere it's being used as
a human-readable string.
In particular, the RH initscripts recognize "TYPE=infiniband" and
"TYPE=InfiniBand", but not "TYPE=Infiniband", which is what we were
writing before.
