This worked fine with PPP because PPP terminates, and NM watches
for that and handles it fine. But modems with pseudo-ethernet ports
don't have anything like that, so we have to watch the modem's state
property instead. This works only with MM 0.5.4 and later (including
0.6).
WiMAX failed distcheck if the iwmxsdk devel files were installed but
--enable-wimax=no was used, since the distcheck configure bits found
the iwmxsdk headers, defaulted WiMAX support to 'on', and then proceeded
to use the generated headers from the top srcdir, where of course
wimax was turned off (due to --enable-wimax=no). Instead, everything
should use the headers from the builddir, which reflects the options
that 'make distcheck' actually selects.
At the same time, re-order various includes everywhere to ensure that
the builddir paths come before the srcdir paths to prevent this from
happening in the future.
The disconnect request gets sent just as a precaution, but usually when
the device fails the modem is already gone from ModemManager and the
Disconnect() method will fail. Just don't log the failure.
Kernel ifindexes are always greater than zero (see dev_new_index()
in net/core/dev.c). Also don't bother warning about ifindex
lookup failures for devices we know aren't kernel network interfaces.
Like IPv4, if the connection contains no IPv6 setting, perform
IPv6 addressing. Since may-fail defaults to TRUE for IPv6, failure
should have no consequence.
When using the either DHCP or STATIC IpMethods the modem manager
or device itself negotiates the PPP session so we need to pass
the authentication preferences through to MM.
Notes:
1/ Using a bitfield now that happens to match the Ericsson
in the lower orders so that it's far more tidy.
2/ Devices that wish to utilise this should observe the
following:
If the bitfield doesn't exist in the dict, then MM uses the
modem default, if it does, MM tries to fulfill the request. If the
modem can only accept one value (Qualcomm-type devices accept only
None, PAP or CHAP with AT$QCPDPP) then MM picks the appropriate one
from the dict if only one of PAP or CHAP was given, otherwise we
default to PAP.
(dcbw: make enum a bitfield instead of the bit position)
When NM was registering all of its enum types by hand, it was using
NamesLikeThis rather than the default names-like-this for the "nick"
values. When we switched to using glib-mkenums, this resulted in
dbus-glib using different strings for the D-Bus error names, causing
compatibility problems.
Fix this by using glib-mkenums annotations to manually fix all the
enum values back to what they were before. (This can't be done in a
more automated way, because the old names aren't 100% consistent. Eg,
"UNKNOWN" frequently becomes "UnknownError" rather than just
"Unknown".)
Different modem implementations in ModemManager are now able to specify specific
maximum durations of the IP configuration setup. This is useful when specific
modems need durations greater than the default 20s (for example, for Satellite
network based modems, where delays are pretty high).
Rather than generating enum classes by hand (and complaining in each
file that "this should really be standard"), use glib-mkenums.
Unfortunately, we need a very new version of glib-mkenums in order to
deal with NM's naming conventions and to fix a few other bugs, so just
import that into the source tree temporarily.
Also, to simplify the use of glib-mkenums, import Makefile.glib from
https://bugzilla.gnome.org/654395.
To avoid having to run glib-mkenums for every subdirectory of src/,
add a new "generated" directory, and put the generated enums files
there.
Finally, use Makefile.glib for marshallers too, and generate separate
ones for libnm-glib and NetworkManager.
Modems take a bit of time, and ModemManager may not quite be
ready for immediate connect after sending the PIN since the
modem isn't enabled. The specific issue was that MM is still
closing serial ports, so if we try to enable too soon we'll
get an error about serial ports being closed.
Don't set default values for the properties, which didn't allow users to
switch off sending echo-request packets. Rather set defaults in editor
or while completing connection for modems.
The NM 'iface' isn't always the IP iface (like for modems) so
to avoid a warning, only flush routes and addresses on deactivate
when the iface can actually handle it.
It was somewhat pointless since the IP config is always known when
stage4 gets scheduled, so why not just pass the config to stage5
immediately? Also helps consolidate the v4/v6 failure handling
logic and makes the operational flow clearer where both v4 and
v6 are active and proceeding in parallel.
Once we've sent a method call over DBus requesting that the modem be
disabled, we should assume that the modem is disabled unless we hear
otherwise. Otherwise, code that checks the modem state immediately
after it gets disabled might think that it's enabled when it almost
certainly is not.
While this should never happen while the PPP manager is alive, modems
can switch their IP method while alive, since the net port is sometimes
discovered after the serial ports have been. This happens for some
devices that have separate drivers for the net and serial sides, like
ZTE Icera-based devices (cdc-ether and cdc-acm) and newer Sierra
devices (sierra and sierra-net). Just be paranoid here and ensure
that the PPP manager gets cleaned up.
Partial attempt at fixing lp:752143
These days more and more devices are showing up that support a
number of different access technology families in the same hardware,
like Qualcomm Gobi (CDMA and GSM), Pantech UM190 (CDMA and GSM),
Pantech UML290 (CDMA and LTE), LG VL600 (CDMA and LTE), Sierra
320U (GSM and LTE), etc. The previous scheme of having device
classes based on access technology family simply cannot handle
this hardware and attempting to add LTE to both the CDMA and GSM
device classes would result in a bunch of code duplication that
we don't want. There's a better way...
Instead, combine both CDMA and GSM device classes into a generic
"Modem" device class that provides capabilities indicating what
access technology families a modem supports, and what families
it supports immediately without a firmware reload. (Gobi devices
for example require a firmware reload before they can switch
between GSM and CDMA). This provides the necessary flexibility
to the client and allows us to keep the API stable when the
same consolidation change is made in ModemManager.
The current code doesn't yet allow multi-mode operation internally,
but the API is now what we want it to be and won't need to be
changed.
deactivate_quickly is misnamed these days; it was originally used
for quickly tearing down a device for sleep and such. But these
days it's used for the bulk of device deactivation. Only the wifi
class used the actual deactivate method. So combine the two and
make device implementations less complicated.
It's the thing that owns the secrets anyway, and it simplifies things to
have the secrets handling there instead of half in NMActRequest and
half in NMManager. It also means we can get rid of the ugly signals
that NMSettingsConnection had to emit to get agent's secrets, and
we can consolidate the requests for the persistent secrets that the
NMSettingsConnection owned into NMSettingsConnection itself instead
of also in NMAgentManager.
Since the NMActRequest and the NMVPNConnection classes already tracked
the underlying NMSettingsConnection representing the activation, its
trivial to just have them ask the NMSettingsConnection for secrets
instead of talking to the NMAgentManager. Thus, only the
NMSettingsConnection now has to know about the agent manager, and it
presents a cleaner interface to other objects further up the chain,
instead of having bits of the secrets request splattered around the
activation request, the VPN connection, the NMManager, etc.
When a user makes an explicit request for secrets via GetSecrets
or activates a device, don't ask other users' agents for secrets.
Restrict secrets request to agents owned by the user that made the
initial activate or GetSecrets request.
Automatic activations still request secrets from any available agent.
Given connection details, complete the connection as well as possible
using the given specific object and device, add it to system
settings, and activate it all in one method.
Instead of a bizare mechanism of signals back to the manager
object that used to be required because of the user/system settings
split, let each place that needs secrets request those secrets
itself. This flattens the secrets request process a ton and
the code flow significantly.
Previously the get secrets flow was something like this:
nm_act_request_get_secrets ()
nm_secrets_provider_interface_get_secrets ()
emits manager-get-secrets signal
provider_get_secerts ()
system_get_secrets ()
system_get_secrets_idle_cb ()
nm_sysconfig_connection_get_secrets ()
system_get_secrets_reply_cb ()
nm_secrets_provider_interface_get_secrets_result ()
signal failure or success
now instead we do something like this:
nm_agent_manager_get_secrets ()
nm_agent_manager_get_secrets ()
request_start_secrets ()
nm_sysconfig_connection_get_secrets ()
return failure or success to callback
Use the interfaces kernel index when we can to avoid unecessary
iface->index lookups; and let callers figure out which address
family they really want to flush.
Some stuff we build (the DHCP manager) gets built independently
so that we can use it for unit tests. For that, we need to build
the logging bits separately too, since the independent DHCP
library can't use them if they are embedded in NM.
