What hash is used to store the password should ideally be an
implementation detail, so that every user of the GUIConfiguration
object automatically agrees on how to handle it. That is currently
distribututed over the confighandler.go and api_auth.go files, plus
tests.
Add the SetHasedPassword() / CompareHashedPassword() API to keep the
hashing method encapsulated. Add a separate test for it and adjust
other users and tests. Remove all deprecated imports of the bcrypt
package.
LoadOrGenerateCertificate() takes two file path arguments, but then
uses the locations package to determine the actual path. Fix that
with a minimally invasive change, by using the arguments instead.
Factor out GenerateCertificate().
The only caller of this function is cmd/syncthing, which passes the
same values, so this is technically a no-op.
* lib/tlsutil: Make storing generated certificate optional. Avoid
temporary cert and key files in tests, keep cert in memory.
* Trigger connection loop on config device addition (fixes#7600)
* Also check for device address equality
* Move EqualStrings from api_test to utils, and use in connections/service.go
* Make sure CommitConfiguration cannot block due on the deviceAddressesChanged channel
* Update lib/connections/service.go

This makes us use TLS 1.3+ on sync connections by default. A new option
`insecureAllowOldTLSVersions` exists to allow communication with TLS
1.2-only clients (roughly Syncthing 1.2.2 and older). Even with that
option set you get a slightly simplified setup, with the cipher suite
order fixed instead of auto detected.
No longer hide the web UI controls for the new untrusted/encrypted
device feature. Testing hasn't been very widespread, but there has been
some and quite a few bugs have been caught and fixed. I believe its time
to not hide it anymore, and cautiously recommend usage. E.g. mention
that the feature hasn't been widely used yet and anyone using it is an
early adopter, but drop the bit about not using it with production data.
We can maybe stress the need for backups in general and especially
using this.
This adds a couple of dummy asset files protected by the "noassets"
build tag. The purpose is that it should be possible for, for example,
CI tools and static analysis things to compile and analyze the source
tree without our custom asset generation step. Also makes `go test -tags
noassets ./...` work without building assets first.
This loosens the ‘is this localhost?’ check to include *.localhost host
names.
This allows for clearer (hence better) names to be used in browsers,
e.g. when accessing a remote syncthing instance ‘foo’ using a ssh port
forward, one can use foo.localhost to remind oneself which one is which.
💡 Without these changes, Syncthing shows a ‘Host check error’ when
pointing a browser at http://foo.localhost/, and with these changes, the
interface loads as usual.
The .localhost top level domain is a reserved top-level domain (RFC 2606):
> The ".localhost" TLD has traditionally been statically defined in
> host DNS implementations as having an A record pointing to the
> loop back IP address and is reserved for such use. Any other use
> would conflict with widely deployed code which assumes this use.

As Wikipedia puts it:
> This allows the use of these names for either documentation purposes
or in local testing scenarios. – https://en.wikipedia.org/wiki/.localhost
On Linux systems, systemd-resolved resolves *.localhost, on purpose:

This splits the ignore getting to two methods, one that loads from disk
(the old one) and one that just returns whatever is already loaded (the
new one). The folder summary service which is just interested in stats
now uses the latter method. This means that it, and API calls that call
it, does not get blocked by folder I/O.
This adds two new configuration options:
// The number of connections at which we stop trying to connect to more
// devices, zero meaning no limit. Does not affect incoming connections.
ConnectionLimitEnough int
// The maximum number of connections which we will allow in total, zero
// meaning no limit. Affects incoming connections and prevents
// attempting outgoing connections.
ConnectionLimitMax int
These can be used to limit the number of concurrent connections in
various ways.
