[Desktop-packages] [Bug 1571522] Re: Detect captive WiFi hotspots
There can be many ways captive portals work and it is tricky being able to support the different ways of detecting this. I've seen some offer redirects, but others offer different status codes to indicate the captive portal, and not all captive portals act properly once things get returned. I would think this comes from network-manager level and not indicator level. ** Also affects: network-manager (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to network-manager in Ubuntu. https://bugs.launchpad.net/bugs/1571522 Title: Detect captive WiFi hotspots Status in Canonical System Image: Confirmed Status in indicator-network package in Ubuntu: Confirmed Status in network-manager package in Ubuntu: New Bug description: Right now it is very annoying that when you connect to a captive wifi portal, the device does not detect that.

One needs to manually open the browser, type a url and get redirected before being able to log in and start e.g. telegram messaging over the wifi connection.

[Desktop-packages] [Bug 1552424] Re: [FFE] NetworkManager 1.2-beta
awe is currently working on getting the update to 1.2 working. Work is ongoing, and needs a few more improvements and patches ported. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to network-manager in Ubuntu. https://bugs.launchpad.net/bugs/1552424 Title: [FFE] NetworkManager 1.2-beta Status in network-manager package in Ubuntu: New Bug description: We really should update NetworkManager to 1.2 (or some other updated stable release) for the LTS, this will allow us to better deal with any bugs that might come up post-release. This new release will also much improve interop with LXC, which has recently been an issue. Other FFEs will be opened for NM VPN plugins and for NetworkManager- applet. NetworkManager-1.2 Overview of changes since NetworkManager-1.0 This is a new stable release of NetworkManager. Notable changes include: * Added an option to enable use of random MAC addresses for Wi-Fi access point scanning (defaults to disabled). Controlled with 'wifi.mac-address-randomization' property (MAC_ADDRESS_RANDOMIZATION key in ifcfg files). * Wi-Fi scanning now utilizes wpa_supplicant's AP list. * Added support for Wi-Fi powersave, configured with POWERSAVE key in ifcfg files. * Added support for creation of more types of software devices: tun & tap, macvlan, vxlan and ip tunnels (ipip, gre, sit, ip6ip6 and ipip6). * The software devices (bond, bridge, vlan, team, ...) can now be stacked arbitrarily. The nmcli interface for creating master-slave relationships has been significantly improved by the use of 'master' argument to all link types. * RFC7217 stable privacy addressing is now used by default to protect from address-based host tracking. The IPv6 addressing mode is configured with IPV6_ADDR_GEN_MODE key in ifcfg files. * Improved route management code to avoid clashes between conflicting routes in multiple connections. * Refactored platform code resulting in more robust interface to platform, less overhead and reduced memory footprint. * Improved interoperability with other network management tools. The externally created software devices are not managed until they're activated. * The Device instances now exist for all software connections and the platform devices are now only created when the device is activated. This makes it possible for connections with device of same name not to clash unless they're activated concurrently. The links are now not unnecessarily present unless the connection is active, avoiding pollution of the link namespace. * NetworkManager now correctly manages connectivity in namespace-based containers such as LXC and Docker. * Support for configuring ethernet Wake-On-Lan has been added. * Added LLDP listener functionality and related CLI client commands. Enabled via LLDP option in ifcfg files. * CLI secret agent has been extended with support for VPN secrets. * The command line client now utilizes colors for its output. * The command line client now sorts the devices and properties for better clarity. * Numerous improvements to Bash command completion for nmcli. * NetworkManager relies on less external libraries. The use of dbus-glib has been replaced with gio's native D-Bus support and libnl-route is no longer used. * Dependency on avahi-autoipd has been dropped. Native IPv4 link-local addressing configuration based on systemd network library is now used instead. * Hostname is now managed via systemd-hostnamed on systemd-based systems. * Management of resolv.conf management can be changed at runtime, private resolv.conf is always written in /run. * NetworkManager can now write DNS options to resolv.conf. * Updated version of systemd network library used for internal DHCP and IPv4 link-local support. * Support for event logging via audit subsystem has been added. * Support for native logging via systemd-journald has been added taking advantage of its structured logging. * Live reconfiguration of IP configuration after changing the settings without reactivation of the device with "nmcli device reapply" command and via D-Bus API. * The API for VPN plugins now supports multiple simultaneous connections. Most popular VPN plugins have been updated to support this functionality. * The libnm library now provides API to access VPN service definitions. * New DHCP_FQDN key in ifcfg files to configure the full FQDN to be sent to the DHCP servers. * The timeout for DHCP requests can now be modified using the 'ipv4.dhcp-timeout' property. * Added multicast_snooping option to BRIDGING_OPTS ifcfg key. * Added support for detecting

Is there any reason to keep both connections active at the same time? Obviously it needs to be able to connect to mobile data when wifi is connected for HERE/agps, but I think it just needs to download satellite data once (I could be wrong it might need to keep downloading this data) -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to network-manager in Ubuntu. https://bugs.launchpad.net/bugs/1270189 Title: Ubuntu Touch devices are using cellular DNS servers over wifi connection Status in Canonical System Image: Confirmed Status in network-manager package in Ubuntu: Confirmed Status in network-manager package in Ubuntu RTM: New Bug description: On my Nexus 4, build 121 with TMobile, when I am on wifi, I correctly get a 192.168 ip and DNS entries for this network (on wlan0) -- fine. When I am in range of cellular data, I get an ip address from TMobile and am given DNS entries that aren't on the same network as the TMobile ip address (on rmnet_usb0). The problem is, the DNS entries from TMobile are preferred over the ones from the wifi network such that while wlan0 is correctly setup as the default route, DNS queries are being made to the TMobile DNS servers over wlan0 because there are no explicit routes to these servers. This is problematic because the remote DNS server may not respond to queries coming from out of network or site policy may disallow the use of foreign DNS servers-- both of which result in slow (or possibly failing) DNS queries since the cellular DNS is checked first. Also, where it did work, these queries could incur charges when the user is intending to use only wifi. In the case of (at least) TMobile, this could be a security concern because the well-known TMobile DNS servers are on the private '10.' network, which opens the possibility for a rogue DNS server to be on the private wifi network with this ip address. This could be fixed in (at least) four ways: 1) when on wifi, don't merge the DNS servers on cellular networks at all which forces the device to use the ones available on the site (wlan0). This is guaranteed to not incur changes 2) when on wifi, merge the DNS server from the cellular network, but add them after the ones on the wifi network. This will try the site's DNS first and only if they fail, fallback to the cellular DNS. This may incur charges under certain circumstances 3) add an explicit route to the cellular DNS servers through rmnet_usb0. This will bypass the site DNS with all queries going through cellular DNS. This will incur charges and would make the device unable to resolve site-local names. 4) same as '2', but also add explicit routes for the cellular name servers. This should only incur charges if wifi DNS fails I think '3' is out. '2' and '4' seems most intuitive (with '4' perhaps most correct).

[Desktop-packages] [Bug 1480877] Re: Access points' "PropertiesChanged" dbus signals freeze UI on mobile devices
@Tony 1) requestUpdate() should be left in, as the backend needs to tell other parts when the update request has been completed. I have tested this, so it does compile. In further testing, it does not look like any clients are requesting updates, so the increased power consumption is coming from somewhere else. 2) The crash is because of dead code, and included change is just a quick fix. Proper fix is to go through this and remove the rest of the dead and unneeded code. 3) If you want this delta as small as possible, it is safe to remove this from the patch and only include #2. There is more dead code in there now that it only relies on settings and active connections, which I will remove in a different patch. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to network-manager in Ubuntu. https://bugs.launchpad.net/bugs/1480877 Title: Access points' "PropertiesChanged" dbus signals freeze UI on mobile devices Status in Canonical System Image: Fix Committed Status in Unity 8: New Status in dbus-cpp package in Ubuntu: In Progress Status in network-manager package in Ubuntu: Incomplete Status in qtbase-opensource-src package in Ubuntu: Fix Committed Status in dbus-cpp package in Ubuntu RTM: Fix Released Status in location-service package in Ubuntu RTM: Fix Released Status in network-manager package in Ubuntu RTM: Incomplete Bug description: Krillin, rc-proposed, r83 DESCRIPTION: I've been trying to track down the cause of the occasional UI freezes on my Krillin device, and I noticed that whenever the UI freezes for 2-4 seconds, I get a burst of "PropertiesChanged" signals in dbus-monitor Here's a log of what's shown in dbus-monitor: http://pastebin.ubuntu.com/11992322/ I'd guess the problem is in the code that actually catches the signals and acts accordingly.

I agree, since nothing controls the connections through QtBearer (and the platform doesn't want that), and AP lists are not allowed in contained apps, it makes sense to simply remove them. I've fixed up that patch in regards to d'tor disconnects, removed some redundant code. And since it was a small change, I fixed up the defaultConfiguration code that would not correctly detect when the default route changed from mobile to wifi, thus possibly allowing network requests to go through expensive mobile data when wifi is available. ** Patch added: "net-beaerer-nm-disconnect-ap-signals3.patch" https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/1480877/+attachment/4523931/+files/net-beaerer-nm-disconnect-ap-signals3.patch -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to network-manager in Ubuntu. https://bugs.launchpad.net/bugs/1480877 Title: Access points' "PropertiesChanged" dbus signals freeze UI on mobile devices Status in Canonical System Image: Confirmed Status in Unity 8: New Status in dbus-cpp package in Ubuntu: In Progress Status in indicator-network package in Ubuntu: Incomplete Status in network-manager package in Ubuntu: Incomplete Status in qtbase-opensource-src package in Ubuntu: In Progress Status in buteo-syncfw package in Ubuntu RTM: New Status in location-service package in Ubuntu RTM: In Progress Status in maliit-framework package in Ubuntu RTM: New Status in network-manager package in Ubuntu RTM: Incomplete Status in sync-monitor package in Ubuntu RTM: New Bug description: Krillin, rc-proposed, r83 DESCRIPTION: I've been trying to track down the cause of the occasional UI freezes on my Krillin device, and I noticed that whenever the UI freezes for 2-4 seconds, I get a burst of "PropertiesChanged" signals in dbus-monitor Here's a log of what's shown in dbus-monitor: http://pastebin.ubuntu.com/11992322/ I'd guess the problem is in the code that actually catches the signals and acts accordingly.

The generic bearer plugin is brain dead, especially when it comes to knowing when it's actually connected or not. Although connectivity-api also suffers from blocking dbus calls, I feel the connectivity-api backend is the right way to go for bearer & QNAM right now. In the least, it will lessen the stress on dbus, as ideally, there should be only one Qt entity getting network-manager properties through dbus on a system. At least the blocking calls will be off loaded from everybody and their brother that happens to use QNAM knowingly or blindly.

That's right, any time QNAM is used it uses the Qt Bearer backend (unless Qt is configure without bearer). In the case of the network- manager backend, it calls the blocking dbus calls to get list of services, and then for every service to get that services properties.

You might be running into those dbus blocking calls in the network-manager bearer backend. The networkmanager bearer plugin currently is using a few blocking dbus calls to get properties and such. see this abandoned change here: https://codereview.qt-project.org/#/c/98090/ This change was abandoned as QNAM is synchronous in nature, and expects defaultConfiguration to be ready right away.

Start InternetCheckercmd with wifi enabled, with the known wifi router unpowered or out of range, while connected to mobile data. (will not work like this when manually enabling/disabling wifi) It will return something like this: phablet@ubuntu-phablet:~$ InternetCheckercmd/InternetCheckercmd (Checker::Checker:14) - configuration ccmni0 QFlags(0x2|0x4|0x8) (Checker::createGetRequest:30) - Initiate HTTP GET Request (Checker::finishedSlot:35) - configuration ccmni0 QFlags(0x2|0x4|0x8) (Checker::finishedSlot:39) - HTTP GET Reply Code: 0 and Name: Unknown error (reply code 0 means success) With the InternetCheckercmd still running, either walk into range of a known/configured wifi, or power on the wifi router that is known and configured, so the phone will auto connect to it. Wait for the wifi indicator to show there is a wifi connection. Notice that the get request is still going through the mobile data connection, instead of the wifi connection. This means anything keeping a QNAM instance and using it to do random get requests will be using expensive mobile data instead of cheaper wifi, even though wifi is connected. Try this again with the patched QNAM and QtBearer plugin, and it will change the configuration which it uses for the get request. ** Attachment added: QNAM Internet checker https://bugs.launchpad.net/savilerow/+bug/1357321/+attachment/4276051/+files/InternetCheckercmd.tgz -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to network-manager in Ubuntu. https://bugs.launchpad.net/bugs/1357321 Title: QNetworkAccessManager doesn't support roaming on Ubuntu Status in Platform API: Invalid Status in The Savilerow project: New Status in network-manager package in Ubuntu: Invalid Status in ofono package in Ubuntu: Invalid Status in qtbase-opensource-src package in Ubuntu: Fix Released Status in qtbase-opensource-src package in Ubuntu RTM: In Progress Bug description: scope images load fine in wifi, but not on hsdpa even when there is good connectivity and browsing works well.

Has that network-manager fix hit ubuntu-rtm/devel yet? Because without these qtbearer/qnam patches, I'm still seeing images loading issues. The problem is not manually disabling the AP, but when moving (roaming) from one to another, i.e. moving from wlan coverage to 3g coverage, or from 3g to wlan If you set up a Wlan AP, connect the phone to it, and then pull the power plug on it so that AP disappears (or walk outside), the 3g connection will become default, but the old non patched QNAM is still holding on to the now non invalid wlan configuration. Refreshing to scopes will result in nothing being downloaded. The generic plugin does not know when something is actually connected or just the interface is 'up'. It does not generate the needed signals for QNAM to continue functioning without tearing down the QNAM object. Even worse, if you bootup with 3g connected, walk into wlan coverage, the QNAM get() request will be going through the still connected 3g connection.

I did more testing of the generic plugin, and it's not as bad as I thought, in that it does signal when interfaces become the default route. But my comment still stands that without these patches (in the least, the patch to QNAM itself is especially needed) the defaultConfiguration internal to QNAM will not switch, which _will_ cause people to wonder why their mobile data is being used while the indicator shows that they are connected to wifi, and _will_ cause people to use up their expensive mobile data. I question the removal of this from TOPBLOCKER's and rtm.

Ok, I think I see the light now. This is an odd one. There seems to be two connection settings (within networkmanager) for the same connection context (even in mako), one being the nm settings configuration that is actually connected (settings/2), and the other that is not flagged as active (settings/0) (both with different UUID). It is this non-active configuration that SmartScopes is holding on to and trying to connect to, which then causes nm to disconnect the other configuration. I can work around this by faking that the Settings/0 is flagged as Active in QtBearer when there is a connection context somewhere with the same context id that is actually active. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to network-manager in Ubuntu. https://bugs.launchpad.net/bugs/1357321 Title: [TOPBLOCKER] QNetworkAccessManager doesn't support roaming on Ubuntu Status in Platform API: In Progress Status in The Savilerow project: New Status in “network-manager” package in Ubuntu: Incomplete Status in “ofono” package in Ubuntu: Invalid Status in “qtbase-opensource-src” package in Ubuntu: In Progress Bug description: scope images load fine in wifi, but not on hsdpa even when there is good connectivity and browsing works well.

[Desktop-packages] [Bug 1357321] Re: [TOPBLOCKER] QNetworkAccessManager doesn't support roaming on Ubuntu
@kgunn72 I think we certainly have moved on to a different bug. Originally, QNAM was not considering mobile data connection at all, because the QtBearer was only using generic plug (which does not know the difference between mobile data and other network interfaces and is not really usable anyway). The NetworkManager backend was also not working as it should. @mathieu-tl I just noticed in comment #10, you mention roaming (as does the bug subject). Roaming in QConfiguration means 'connection migration' where connections are migrated seamlessly to and from wlan/mobile (kind of like what mobile does moving from tower to tower), i.e. a streaming media would continue uninterrupted moving from wlan to mobile data. I believe it has been supported only on Symbian which did the connection migrations at the platform level . QNAM should now at least switch the configuration it uses when the default route changes to one that is usable, which is about the closest we can get to connection 'roaming' at this point. Previously a client would have to tear down and create a new QNAM. Now, a QNAM get request should succeed regardless when the QNAM was made. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to network-manager in Ubuntu. https://bugs.launchpad.net/bugs/1357321 Title: [TOPBLOCKER] QNetworkAccessManager doesn't support roaming on Ubuntu Status in Platform API: In Progress Status in The Savilerow project: New Status in “network-manager” package in Ubuntu: Incomplete Status in “ofono” package in Ubuntu: New Status in “qtbase-opensource-src” package in Ubuntu: In Progress Bug description: scope images load fine in wifi, but not on hsdpa even when there is good connectivity and browsing works well.

[Desktop-packages] [Bug 1384776] Re: Occasional hang in unity 8 dash on the phone
QNAM uses QtBearer, which means those are handled by the NetworkManager backend, which I am currently trying to fix up. There are two ways of diserning online status with QtNetwork. 1) QNetworkConfigurationManager has isOnline() method, this can be done on the defaultConfiguration(). 2) QNetworkConfigurationManager has allConfigurations which can take an argument of QNetworkConfiguration::Active which will give a list of all active (online) configurations. Both of which are a bit heavy if only being used for discovering online status. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to network-manager in Ubuntu. https://bugs.launchpad.net/bugs/1384776 Title: Occasional hang in unity 8 dash on the phone Status in “network-manager” package in Ubuntu: In Progress Status in “unity8” package in Ubuntu: Triaged Bug description: The dash is sometimes hanging on the phone. See the attached backtrace. The issue is as follows: we are maintaining a client-side tree of all NetworkManager devices. When we see that a new device has been added, we query its properties in order to build our local proxy. Doing this means that we are making QtDBus calls from a signal handler. Due to a bug in QtDBus this is not safe. libdbus-1 has a recursive lock on its DBusConnection. When the signal arrives, the lock is acquired and the sginal handler is run. The signal handler can make DBus calls (which also require the lock) because the lock is recursive. QtDBus also has a lock that is always acquired before the libdbus-1 connection lock is acquired. Unfortuntaely, the QtDBus lock is not acquired in the case of the incoming call from DBus -- only the DBus lock is. If another thread tries to do an unrelated DBus call meanwhile, it will acquire the QtDBus lock first and then the DBus lock (which is held because of the signal that arrived). Once the signal handler gets to the point of wanting to make a DBus call (in order to query the properties of the just-added network device) it will attempt to acquire the QtDBus lock. This is a lock-inversion deadlock. There are at least three bugs here: 1) QtDBus should be fixed in order to avoid this sort of lock inversion problem. Even if we fix this one situation, it seems quite likely that issues like this will arise again. 2) QNetworkManager should avoid the issue in QtDBus until such a time as it is fixed. This could be done by dispatching to a worker thread on receipt of signals so that the queries are done in a fresh call stack (without the libdbus-1 lock held). 3) Apparently the only reason we are using NetworkManager at all is in order to know if we are on a 3G connection or not (in order to avoid too much data charges). This would be much easier to do if NetworkManager provided a property that we could watch directly instead of bringing up an entire tree of objects in order to answer a very simple question. To that end I've filed https://bugzilla.gnome.org/show_bug.cgi?id=739080 which we can hopefully get addressed relatively quickly. I consider 3) to be the real fix as far as we are concerned, but we should probably ensure that the Qt people know about 1) and 2). Either of those could function as a workaround for us in the meantime, but the idea that we are creating this complex object tree to answer a simple question is ridiculous, so we should really fix that directly.
