This is the same issue as #2014/#2062. Bootstrap doesn't like having two dialogs
open at once: it marks the body has having no dialogs open when the first dialog
is closed, regardless of whether the second dialog is still open.
This means that scrolling doesn't happen properly, and the user cannot
scroll to the dialog's 'close' button.
Work around this by making sure the first dialog (the settings page) is fully closed
before the second dialog (usage preview) is opened.
This replaces the current 3072 bit RSA certificates with 384 bit ECDSA
certificates. The advantage is these certificates are smaller and
essentially instantaneous to generate. According to RFC4492 (ECC Cipher
Suites for TLS), Table 1: Comparable Key Sizes, ECC has comparable
strength to 3072 bit RSA at 283 bits - so we exceed that.
There is no compatibility issue with existing Syncthing code - this is
verified by the integration test ("h2" instance has the new
certificate).
There are browsers out there that don't understand ECC certificates yet,
although I think they're dying out. In the meantime, I've retained the
RSA code for the HTTPS certificate, but pulled it down to 2048 bits. I
don't think a higher security level there is motivated, is this matches
current industry standard for HTTPS certificates.
- Move to ipinfo.io for geoip, rather than Telize. Telize has been closed
down. ipinfo.io has apparently got decent availability, and allows
1,000 requests per day on the free tier. Since requests are made by the
client, this should be more than enough (and the total across all clients
should still be less than this).
- Fix issue where one nonresponsive relay would cause 'data unavailable'
to be shown for many relays. This was caused by the relay status
promise not being correctly added to the list of things being waited
for before the map was rendered. Any delayed relay status requests
would therefore occur after the map was rendered, which was too late.
