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.
> – https://tools.ietf.org/html/rfc2606
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.
Our authentication is based on device ID (certificate fingerprint) but
we also check the certificate name for ... historical extra security
reasons. (I don't think this adds anything but it is what it is.) Since
that check breaks in Go 1.15 this change does two things:
- Adds a manual check for the peer certificate CommonName, and if they
are equal we are happy and don't call the more advanced
VerifyHostname() function. This allows our old style certificates to
still pass the check.
- Adds the cert name "syncthing" as a DNS SAN when generating the
certificate. This is the correct way nowadays and makes VerifyHostname()
happy in Go 1.15 as well, even without the above patch.

This changes the error handling in loading ignores slightly:
- There is a new ParseError type that is returned as the error
(somewhere in the chain) when the problem was not an I/O error loading
the file, but some issue with the contents.
- If the file was read successfully but not parsed successfully we still
return the lines read (in addition to nil patterns and a ParseError).
- In the API, if the error IsParseError then we return a successful
HTTP response with the lines and the actual error included in the JSON
object.
- In the GUI, as long as the HTTP call to load the ignores was
successful we can edit the ignores. If there was an error we show this
as a validation error on the dialog.
Also some cleanup on the Javascript side as it for some reason used
jQuery instead of Angular for this editor...
Group the global list of files by version, instead of having one flat list for all devices. This removes lots of duplicate protocol.Vectors.

Storing assets as []byte requires every compiled-in asset to be copied
into writable memory at program startup. That currently takes up 1.6MB
per syncthing process. Strings stay in the RODATA section and should be
shared between processes running the same binary.
This adds the functionality to run a user search with a filter for LDAP
authentication. The search is done after successful bind, as the binding
user. The typical use case is to limit authentication to users who are
member of a group or under a certain OU. For example, to only match
users in the "Syncthing" group in otherwise default Active Directory
set up for example.com:
<searchBaseDN>CN=Users,DC=example,DC=com</searchBaseDN>
<searchFilter>(&(sAMAccountName=%s)(memberOf=CN=Syncthing,CN=Users,DC=example,DC=com))</searchFilter>
The search filter is an "and" of two criteria (with the ampersand being
XML quoted),
- "(sAMAccountName=%s)" matches the user logging in
- "(memberOf=CN=Syncthing,CN=Users,DC=example,DC=com)" matches members
of the group in question.
Authentication will only proceed if the search filter matches precisely
one user.
- In the few places where we wrap errors, use the new Go 1.13 "%w"
construction instead of %s or %v.
- Where we create errors with constant strings, consistently use
errors.New and not fmt.Errorf.
- Remove capitalization from errors in the few places where we had that.
This adds error returns to model methods called by the protocol layer.
Returning an error will cause the connection to be torn down as the
message couldn't be handled. Using this to signal that a folder isn't
currently available will then cause a reconnection a few moments later,
when it'll hopefully work better.
Tested manually by running with STRECHECKDBEVERY=0 on a nontrivially
sized setup. This panics reliably before this patch, but just causes a
disconnect/reconnect now.
As foretold by the prophecy, "once the database refactor is merged, then
shall appear a request to propagate errors from the store known
throughout the land as the NamedspacedKV, and it shall be good".
* gui, lib/api: Adds support for prefers-color-scheme on default theme (fixes#6115)

The CSS is always loaded if there is no support for `matchMedia`.
This adds a certificate lifetime parameter to our certificate generation
and hard codes it to twenty years in some uninteresting places. In the
main binary there are a couple of constants but it results in twenty
years for the device certificate and 820 days for the HTTPS one. 820 is
less than the 825 maximum Apple allows nowadays.
This also means we must be prepared for certificates to expire, so I add
some handling for that and generate a new certificate when needed. For
self signed certificates we regenerate a month ahead of time. For other
certificates we leave well enough alone.
This adds a field `guiAddressUsed` to the system status response, that
holds the current listening address actually in use. This may be
different from the one stored in the config because it may have been
overridden by environment or command line flag.
The GUI now checks this field to see if we are listening on localhost.
If we are not, the authentication required warning is displayed,
regardless of the *configured* listening address.
This is an experiment in testing, based on the advise to always call
t.Parallel() at the start of every test. Doing so makes tests run in
parallel, which is usually faster, but also exposes package level state
and potential race conditions better.
To support this I had to redesign the CSRF manager to not be package
global, which was indeed an improvement. And tests run five times faster
now.
* lib/api, lib/connections, gui: Show connection error for disconnected devices (fixes#3345)
This adds functionality in the connetions service to track the last
error per address. That is in turn exposed in the /rest/system/status
API method, as that is also where we already show the listener status
from the connection service.
The GUI uses this info where it lists addresses, showing errors (if any)
in red underneath each address.
I also slightly refactored the existing status method on the connection
service to have a better name and return typed information.
