When they are treated as system battery, it will make the system poweroff/suspend/hibernate when some Bluetooth device has critical low battery. It is a very annoying behavior for the users. Originally, there is no such Bluetooth battery information until Ubuntu 12.04 brings linux-quantal-lts and linux-raring-lts, so those linux kernels also bring this issue. [Test Case] * Pair some Bluetooth devices, such as Apple Wireless Mouse or Apple Wireless Keyboard. * Click the power indicator and you can find Apple Wireless Mouse is listed as system battery, and there is no Apple Wireless Keyboard. If you open gnome-power-statistics, you can find the 'Supply' field of Apple Wireless Mouse is 'Yes' but it should not be. [Regression Potential] * There is no obvious regression as I know. [Other Info] * Most patches are from upstream, modified to fix the conflicts, and made by the same developer (i.e. fourdollars). * We need another patch from https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=d0a934b764c67b4bf626f5b7cf725a6e3066afd2 to make Apple Wireless Keyboard showing. [Original Bug Description] This is a weird one... the system is an HP Pavilion 23 All In One and is powered by a large power supply brick. I currently have an Apple Magic Mouse connected via Bluetooth. As soon as the mouse is connected, the Battery indicator shows up and clicking on that shows that the system is reading my mouse as a battery! See the attached screen shot for what I see in the Power status. Looking at hcitool: ubuntu@201206-11396:~$ hcitool dev Devices: hci0 9C:B7:0D:80:71:DB To make matters even more weird, I actually observed the battery indicator go from full to "Critically Low" and the system suspended itself. Keep in mind, again, that this system has NO battery, it's reading my bluetooth mouse as a battery device. I disconnected the magic mouse and the battery indicator went to Empty Red outline and status showed Battery Disconnected.

[Touch-packages] [Bug 1721223] Re: Networkd fail to set ip address between leases if ip address changes on UbuntuCore
Want a seamless website to transfer money through mobile.

[Test Case] Add a device, and assign two IPv4 addresses. First one, with a short lease time. Second one, with a different ip and a longer lease time. Second one should be treated as secondary ip address, and upon expiry of the first one, should be promoted and become primary ip address. The below scripted instructions simulate this: sudo ip link add name testleases type dummy sudo ip address add 192.0.2.10/27 dev testleases \ valid_lft 5 preferred_lft 5 sudo ip address add 192.0.2.11/27 dev testleases \ valid_lft 11 preferred_lft 11 ip address list dev testleases | \ grep -q 'inet 192.0.2.10/27 scope global dynamic testleases' \ && echo ok || echo not ok ip address list dev testleases | \ grep -q 'inet 192.0.2.11/27 scope global secondary dynamic testleases' \ && echo ok || echo not ok sleep 6 ip address list dev testleases | \ grep -q 'inet 192.0.2.11/27 scope global dynamic testleases' \ && echo ok || echo not ok sudo ip link del dev testleases [Regression Potential] * This changes the default kernel behaviour, previously upon expiry of the primary address, secondary addresses were removed as well. Which is imho silly. * comparing networkd renewal with isc-dhcp renewal the semantics are quite different. Upon acquiring new ip address, isc-dhcp would instantly flush existing ip address, and add a new one. Networkd add the new address as secondary, and waits for old one to expire first before promoting / switching to using the new ip address. IMHO kernel should have an API to promote secondary ip address to a primary one. * This update also applies other safe-looking options, which are currently also already applied via sysctls shipped in other packages # Source route verification net.ipv4.conf.default.rp_filter = 1 net.ipv4.conf.all.rp_filter = 1 # Do not accept source routing net.ipv4.conf.default.accept_source_route = 0 net.ipv4.conf.all.accept_source_route = 0 # Enable hard and soft link protection fs.protected_hardlinks = 1 fs.protected_symlinks = 1 * This update also applies the following upstream/bufferbloat.net recommended setting # Fair Queue CoDel packet scheduler to fight bufferbloat net.core.default_qdisc = fq_codel * [~racb] There are complex network setups out there, such as HA with corosync/pacemaker, OpenStack Neutron, and that kind of thing. If this fix were SRU'd, will all of these things in the wild cope with this sysctl change? [Other Info] * Original bug report Hi there, we found a replicable issue that involves the Ubuntu Core networking and causes complete loss of connectivity. We run a custom board with ubuntu core: the architecure is amrhf. We replicated this issue with an official Ubuntu Core image on a Raspberry Pi: other platform was been tested. It shows that it is a snap core problem which interests networkd: we use the default network stack based on networkd + netplan. Below steps to replicate the issue. 1)Setup a dhcp server for lease of about some minutes (i.e 10 minutes). 2)Boot the board and wait for get an ip from dhcp server 3)Before the lease expires, set a reservation for a different ip address Depending on lease duration before the lease expires( for 10 minute we have 2 minutes before ), networkd configure the new address in addition to the previous one. When the lease expire both ip address ( the prevoius and the new one ) disappear from the interested network interface. Depending on lease duration before the second lease expires ( for 10 minure we have 2 minutes before ) networkd configure only the new ip address on the network interface and the ping toward an outside host work properly. During the test the dhcp server records correctly leases and their duration. We check directly from co
