Consider the following scenario:
1. We send a UDP broadcast
2. We receive a reply from 192.168.0.1 with device ID "foo"
3. We connect to 192.168.0.1, and find that the device's certificate
is actually for a different ID "bar". This could be because the
packet did not actually originate from 192.168.0.1, or this host is
malicious / malfunctioning.
4. We remember that device ID "foo" has certificate with common name "bar".
5. When we finally attempt to connect to the real device ID "foo", we
reject their certificate (common name "foo"). We can now never
successfully connect to "foo".
On some network (mis-)configurations, this completely prevents
kdeconnectd from connecting to any peers, because a reply which is
seen as originating from the local interface address will cause
kdeconnectd to immediately connect to itself and remember its own
certificate.
Address this by using the certificate display name of the peer, which
will match the real device ID.
The key is a sha256 of both devices' certificates. Both should generate the
same key, so hey user can check they are pairing against the right device.
Thanks Matthias Gerstner <mgerstner@suse.de> for reporting this.
The package will arrive eventually, and dataReceived will be emitted.
Otherwise we just end up calling dataReceived to no end.
Thanks Matthias Gerstner <mgerstner@suse.de> for reporting this.
Healthy identity packages shouldn't be that big and we don't want to
allow systems around us to send us ever humongous packages that will
just leave us without any memory.
Thanks Matthias Gerstner <mgerstner@suse.de> for reporting this.
## Summary
LanLinkProviderTest fails on Windows. This patch fixes that.
I believe the root cause is that we are using a shared UDP socket to listen for identity broadcasts both in the LanLinkProvider and in the test. Apparently this works on Linux, but on Windows the LanLinkProvider picks up its own identity packet and pairs with itself.
This patch gives a parameter to LanLinkProvider to allow it to listen and broadcast on different ports, then uses that ability in the test to make the test pass on Windows.
## Test Plan
### Before:
lanlinkprovider test fails, first because it can't bind its UDP listener socket, and then because Windows seems to handle shared sockets differently than Linux, so the UDP broadcasts were not reaching the test's listener.
### After:
lanlinkprovider test seems to pass reliably both in my Windows VM and in the CI
Summary:
As mentioned on telegram, there are some fundamental issues with bluetooth. The only approach I could get working was multiplexing: manually sending multiple streams of data over a single connection.
This is the description of that multiplexing protocol. I have an implementation of this protocol, but I'd first like some feedback to see if this is what we're going to use before finishing up those patches.
See the document itself for more details. I make the protocol forward-compatible, although I don't expect we will need ever that.
Test Plan: None, this is just a description.

Summary:
When android closes the payload socket (cancel share) calling m_socket.close() results
in a recursive call to onError eventually leading to a segmentation violation
Test Plan:
Install D16491, share a large file from desktop to android and cancel the share on Android through
the notification. kdeconnectd crashes almost 100% of the time. (It doesn't crash when it detects
a disconnect in sendNextPacket)

Summary: If the identity packet is split across two packets, then save it until we get a notification that more data is available for reading over the bluetooth link.
Test Plan: Connect a phone and laptop over Bluetooth, and verify that both the phone and laptop are able to see each other, and that either side can start and successfully go through the pairing process.

Summary:
Combine multiple upload jobs for files into a single KCompositeJob so only 1 notification will be shown
Includes changes introduced in D16279
Test Plan:
1. Share of multiple files is performed using 1 composite job
Setup:
- Select multiple (big) files in dolphin and share with an Android device
Result:
- The files will be transferred using 1 CompositeUploadJob and showing only 1 notification
2. Share of file while another share is already running adds job to existing composite job
Setup:
- Select multiple (big) files in dolphin and share with an Android device
- Share an additional file with the same Android device
Result:
- The files are all transferred using 1 CompositeUploadJob and showing only 1 notification
- The notification is updated after adding the last file
3. Other packets are transmitted as usual
Setup:
- Setup sharing desktop notification with device
- Share a big file with an Android device
- Generate a desktop notification (eg. sending or receiving an email)
Result:
- Notification packet is send immediately

Summary:
Main change is to use libkeepalive to wake up the system to ensure connections stay alive
Other minor changes are:
-Log daemon messages for debugging purposes
-Add way to forece refresh of device list
-Minor spec improvements
The keepalive changes certainly seem to help, not sure if it completely solves the problems
The logging changes are temporary, and I could use them locally, but they only affect sailfish users
Im not sure if the refresh method is correct, but seems to force the daemon to check for devices

Port daemon buld system
Require CoreAddons on Sailfish
Port plugins build for sailfish and include the ping plugin for now
Final build changes for sailfish.

Summary:
Change all member variables to the form m_fooBar because it is the preferred form in Qt (it was half and half between this and mFooBar, and a minority didn't have anything).
Place all references and pointers on the side of the type since it is the majority.
Basically:
- mFoo -> m_foo
- foo -> m_foo (if it is a member variable)
- Type &ref -> Type& ref
- Type *ptr -> Type* ptr

We stop using a buffer so it's less memory intensive and allows for larger files to be sent.
With current KIO has CPU usage issues, there's a patch in review that fixes them.
BUGS: 378488
Summary:
QSslSocket is already a QIODevice so just use that.
Should fix the issue of transfering *big* files.
Unfortunately this seems to trigger a bug in KIO and CPU usage goes through the roof, so haven't really been able to test it does actually fix things.

Summary:
There is currently an issue where the device doesn't send the correct IP address for sshfs when a VPN is present.
Instead of asking the device to find and send its address, we can store it from when the device link is created then reuse it.
Test Plan:
All unit tests pass.
In these different situations:
- without a VPN
- with a VPN running
- with a VPN started then stopped (the tun interface might still be there)
Try to remotely browse the device. It should work in all cases.

Summary:
The use of Q_FOREACH is advised against (https://doc.qt.io/qt-5/qtglobal.html#Q_FOREACH) since Qt 5.7 and will eventually be removed from Qt.
I replaced all occurrences with the range-for loop introduced in C++11 (except for the one in daemon.cpp in deviceIdByName which might have a bug / typo in it).
I added const to the container or casted it with qAsConst when appropriate to avoid unnecessary copies.
(This is my first submission. I did all the unit tests, and they all passed but I don't know how to show it here.)
